CHALLENGES FOR FLEXIBLE DISPLAY
Flexible Display: every single layer needs to be flexible!
TFT (electrodes, channel, dielectric, passivation…)
Backlight (LCD display only)
Frontplane (LC cells, polarizers, color filter substrate…)
Encapsulation (OLED only)
Touch sensor (glass, electrodes..)
Cover Lens and coatings (AR, anti fingerprint…)
• In addition to the requirement on each individual layer, delamination and creasing of the stacked layers
must be eliminated.
• The total number of layers and the total thickness must be minimized to reduce the stress experienced by
the layers.
• Ideally, the structure must be designed so that the most fragile and critical layer can be moved to the
neutral plane (experiencing the least stress) in the stack.

(b) gate-insulator deposition, (c) channel layer
deposition (d) source/drain (S/D) definition, (e)

• In “Bottom Emission” display structures, the light generated by the pixel is emitted toward the
TFT. In this configurations, the TFT array therefore blocks some of the light or reduces the active
surface of the pixel. It is therefore important to minimize the size of the TFT circuitry to increase
display brightness.

2016 TFT GEOGRAPHIC BREAKDOWN
• Korea still dominates with close to 35% of worldwide capacity, followed by Taiwan with 30%.
• China currently represents 27% of the total capacity but is expected to become #1 by 2018 and capture 38% of the
total

DISPLAY MARKET: PANEL CONSUMPTION THROUGH 2022
• We estimate that the demand for TFT
display panels will reach XXX Millions
of m2 in 2016 and increase to XXXM
of m2 by 2022.
• Demand is strongly dominated by
large displays: television and
computer monitors. Smartphones
come third despite their smaller area
thanks to very high volumes. Together,
those 3 segments represent > XX%
of the total.
• Wearables (represented by the
categories “smartwatches” and “other
wearable”) as well as embedded
displays (automotive etc…) are
expect to experience fast growth but
remain a small fraction of about XX%
of the total TFT market.
• Note that “other wearable” category
is a catch all category to account for
wearable devices that are not
smartwatches. Those include
wristband, fitness trackers etc… and
possibly new applications.

OTFT PERFORMANCE: HYPEVERSUS REALITY.
• Communication of OTFT performance
is often focused on mobility. But other
parameters such as homogeneity,
reliability, manufacturability, cost of
ownership etc.. are equally important.
• State of the art molecular engineering
allows to deliver on all those criteria: all
the building blocks are ready in the lab.
But bringing it all together is another
challenge.
• Ultimately, the best OSC for mass
production of devices might not be the
one with the highest electrical
performance but rather, one designed
for the application that offers the best
compromise on those requirements.
• Material suppliers and OTFT
manufacturers will eventually develop
increasingly versatile process and
material toolboxes allowing them to
adjust the materials and the TFT
process to each application.

SMALL MOLECULES VS POLYMERS
• While mobility is a critical parameter, reproducibility and processability
are equally important.
• Small molecules tend to be ahead in term of performance but
crystallization is difficult to control. This creates homogeneity and
reproducibility issues.
• Amorphous and polymer materials have a wider process window but
lag in term of performance.
Small
molecule and
polymer each
have their
pros and cons.
But materials
and processes
have improved
dramatically
for both over
the last few
years.

PIXEL DENSITY AND CHANNEL LENGTH
• As the resolution of mobile displays increases, the available surface for the TFT circuit decreases. In the last 2 generations of
Samsung’s Galaxy S6 and S7 phones (discussed below), we estimate that the 5 transistors + 2 capacitor + data lines required to
drive each subpixel must fit in a ~ XX x XX µm2 box (Samsung uses a top emission structure so the circuit can occupy the
entire pixel area). This estimate was confirmed by our sister company “System+ Consulting” which conducted a tear down
analysis of the Galaxy S6 (next pages)
XX µm
The human eye is most sensitive to green, especially for high resolution luminance
information. The Galaxy displays exploit this feature and use a pentile diamond
subpixel arrangement in which green pixels are interleaved with red and blue pixels:
• The green subpixels are mapped to input pixels on a one to one basis, reconstructing
the luminance signal to the display resolution (1440 x 2560). The red and blue
subpixels are subsampled, reconstructing the chromatic signal at a lower resolution.
• The Red, Green, and Blue sub-pixels have different sizes. The blue ones are the
largest because of the low material efficiency and human eye response sensitivity.

BILL OF MATERIAL
• The level of complexity in the molecular engineering and manufacturing process of the OSC is not too different from that of
OLED materials such as the ETL, HTL etc... As volume increase, the cost of the OSC material could decrease toward similar
levels (<$XX/g)
• The cost per gram of the gate dielectric is lower than that of the OSC but offers less opportunity for cost reduction. Long
term cost will depend on the chemistry and the level of functionalities put into them (crosslinked, photo-patternable etc…).
• The binder material used in the ink formulation is not highly engineered and generally low cost, to the exception of
companies that use a low performance polymer semiconductor.
• We estimate that the BOM for OTFT could drop by 40 to 50% over the next 3-5 years and a factor of 2.5 to 3x if adoption
rate enable high volumes and economies of scale. Ultimately, transition to an additive manufacturing process (inkjet or other
printing technology) could further reduce the cost.

OSC AND OGI REVENUE FORECAST THROUGH 2022
• The base scenario shows that under the current
technology roadmap and status of the industry,
OTFT will remain a niche market. The market for
OSC materials remains small and can’t support
more than a couple of companies able to capture
the most value by selling all materials in the stack.
• Under this scenario, it is not clear if the industry
will reach a critical mass to allow a massive take
off. Will material suppliers and panel makers
continue to invest to enable a larger market?
• Our “breakthrough” scenarios illustrate how
further technology advancements could enable a
much larger market. The underlying assumption
for those scenario are:
• The “Printing scenario” accelerates
penetration of AMOLED TVs versus LCD by
reducing manufacturing cost. It provides incentive
for panel makers to accelerate development of
printable TFTs. This enables OTFT penetration in
TVs
• The “Vertical TFT scenario” accelerates OTFT
performance and increases OSC consumption per
unit surface.
To create a
significant
market, a
technology
breakthrough, or
an acceleration
of the current
OTFT roadmap
is required.

SMARTKEM (1)
• SmartKem was founded in 2009 and is based in Manchester (UK). The company sells or licenses its semiconductor inks and has the ability to
deliver test kits including full TFT arrays[1] . As of Q4-2015, the company had 35 employees, rising to 40 by the end of 2016. The team includes
former employees of Samsung, Merck, Kodak, Liquivista, CDT,Avecia, ICI, Philips and Qualcomm.
• SmartKem has announced 4 joint-development agreement (JDA) and 2 Letters of intent (LOI) with various partners including some major
Asian display manufacturers. The intention of these agreements is to transfer SmartKem OSC technology into existing production lines at
those display manufacturers once process feasibility has been established.
• SmartKem also has a JDA with BASF and in August 2014, the company raised €3 million in a series A funding including €1 million from BASF
ventures and other investors. BASF stated that “The technologies and portfolios of both SmartKem and BASF have complementary aspects; moreover,
BASF has a long experience on bringing technologies from an early stage to commercialization, leading to collaboration to help speed up the market
penetration of flexible organic electronics. In this case, BASF VC has been supporting the company in their prioritization of the infrastructure needed to
commercialize their products, drawing on experience from BASF’s core chemical business”.
• SmartKem technology platform marketed under the trademark truFLEX™ consists of high mobility organic semiconductor molecules and

When trying to build a flexible display panel, the
Thin Film Transistor (TFT) matrix is one of the
most challenging and fragile functional layers.
Interest in OTFT emerged in the mid-2000s when
mobility reached values similar to amorphous
silicon (a-Si), the dominant display backplane
technology. This triggered a flurry of activity at
leading display manufacturers, and prototypes
rapidly emerged. Besides fast-improving electrical
performance, OTFT’s intrinsic flexibility made
the technology ideal for the realization of flexible
displays. In 2007, the first ever flexible AMOLED
panel was demonstrated by Sony and featured an
organic TFT.
However, interest waned as performance and
homogeneity issues persisted, and other TFT
technologies like LTPS and metal oxide emerged.
Nevertheless, organic semiconductor companies
kept perfecting their molecules and ink
formulations, gaining a better understanding of the
interaction between the materials, the transistor
structure, and the manufacturing process.
Consequently, performance in the lab improved
by another order of magnitude. Combined with
the explosive growth of flexible displays and
the promise of a cost-efficient, solution-based
manufacturing process, interest in OTFT has
renewed.
Panel makers remain cautious, but a handful in
Taiwan and China are currently attempting to
retrofit older Gen 2.5 - 4.5 fabs with OTFT. These
first attempts to move OTFT into mass production
will be critical for the technology’s future. Failure in
these initial industrialization attempts could be fatal
for the OTFT industry, or, at the very least, set it
back many years. However, if OTFT proves that it
can be mass produced and enables panel makers
to revive those obsolete fabs with high-margin
flexible displays, there are no fundamental barriers
prohibiting the technology from being quickly scaled
up to fabs Gen 8 or above, and possibly challenge
the vast market for traditional a-Si based panels like
LCD TV, monitors, etc. In the long-term, because
they are inherently solution-processable, OTFTs
are also an ideal backplane candidate for additive
manufacturing and fully printed displays.
This report presents a detailed review of flexible
displays, including an analysis of technical challenges
(frontplane, backplane, substrates), manufacturing
status, key players, and technologies.
This report also provides a complete review of
established TFT backplane technologies.

ORGANIC SEMICONDUCTOR (OSC) SUPPLIERS HAVE MORPHED INTO FULL
SOLUTION PROVIDERS
The display panel industry tends to require high
capex in order to generate fairly low margins.
Companies are therefore relatively conservative
when it comes to switching to new TFT. They look
for technologies that:
• Are highly compatible with existing process and
equipment.
• Generate higher margins than the incumbent
technology by allowing higher added-value
products (OLED, flexible displays) and/or reduced
manufacturing costs.
ORGANIC THIN FILM TRANSISTOR (OTFT) 2016: FLEXIBLE DISPLAYS AND OTHER APPLICATIONS
ORGANIC TFTs ARE SEARCHING FOR THEIR FIRST KILLER APPLICATION
OTFT mobility in the lab now exceeds 10 cm2
/vs,
with record values up to 40 cm2
/vs, theoretically
good enough to drive all display types and compete
with all TFT technologies. But while these results are
a good indication of the progress made with organic
semiconductors, they have been obtained in conditions
far from practical in actual fabs and commercial devices.
Current realistic fab-level performance stands in the
range of 1 - 2 cm2
/vs, with a credible path toward 3 - 5
cm2
/vs over the next 18 months - 3 years, and possibly
10 cm2
/vs and above within 5 - 10 years.
At the current level, OTFTs are already superior to
the dominant a-Si platform and enable a whole new
range of very cost-effective, flexible electrophoretic
and LCD displays with a bending radius as low as 30
mm. Not exactly “foldable”, but flexible enough to
conform to curved surfaces in all application types,
such as embedded displays in automotive, consumer
appliances, and digital signage. These displays also
feature reduced weight and thickness and improved
ruggedness from their plastic-based construction.
The aforementioned applications could become a
stepping stone for OTFT, allowing panel makers
to validate and optimize the technology in their
Gen 2.5 - 4.5 fabs and prepare to scale up to larger
substrates while material suppliers fine-tune their
molecules to reach performance sufficient to drive
mid-pixel density OLEDs. This would unlock a whole
new range of applications by enabling cost-effective
manufacturing of low power consumption, fully
flexible displays for wearable and mobile applications.
From there, it remains to be seen if performance
will further improve in order to serve the high-end
OLED market, or if OTFT can deliver on its cost-
effectiveness promises. If so, OTFT could become
a credible alternative to a-Si in the manufacture of
large LCD panels, enabling higher resolution and
higher brightness - features that are critical to the
UHD TV market’s emergence.
This report focuses on OTFT display applications and
the associated market volume for the period 2016 –
2022, broken down in 13 segments. Moreover, this
report provides an analysis of market volume and revenue
for organic semiconductors (OSC) and gate insulators (i.e.:
OGI). Our forecasts have been developed on the basis of
different scenarios, taking into account potential future
technology breakthroughs (i.e. printing process, vertical
transistors).

Organic semiconductor suppliers have realized that
success means offering turnkey solutions comprising
the full material stack, and processes as compatible as
possible with old a-Si equipment. This means photo-
patternable, cross-linkable materials that can be
processed with existing broadband lithography tools
already present in the fab, and which can withstand
traditional patterning and etching techniques.
In the short-term, this puts significant stress on
companies that started as small teams of organic
materials experts. These companies now must access
additional capital and set up partnerships in order
to access fab equipment and develop a full process
toolbox.
However, in the long-term this will permit surviving
companies to capture more added-value than by
simply supplying the channel material.
This report presents a detailed analysis of OTFT, including
benefits, challenges, performance status, and roadmaps.
Additionally, this report provides an analysis of OTFT
manufacturing (technologies, structure, etc.), cost of
ownership, and competitive landscape (i.e. supply chain,
OSC suppliers). Company profiles for key players are also
included.

  • 14. 14 MAJOR TYPES OF FLEXIBLE SUBSTRATES Flexible Glass (Corning “Willow”, Schott…) Metal foils (Stainless steel…) High Temperature Polymer optical Films (PI, PES, PEEK…) Common optical polymer films (PET, PEN, PC,TAC, PMMA…) • Mechanical and thermal characteristics well suited forTFT manufacturing process. • Good oxygen and moisture barriers (no need for back encapsulation layer). • Fairly low cost • Not transparent. • Poor surface roughness (require planarization layer or chemical-mechanical polishing) • Must be isolated to avoid parasitic capacitance with theTFT circuits. • Can’t restored to original shape once bent at a low radius. • Excellent optical properties • Process ready surface • Good oxygen and moisture barrier. • Low CTE • Can’t be bent to small radius (2016 best in class: 9 mm). • Break easily, challenging to handle in manufacturing. • Excellent optical transparency. • Low cost. • Tend to birefringent: not suitable for LCD. • High CTE • Poor surface roughness (require planarization layer) • Low glass transition temperatureTg: unsuitable for traditionalTFT processes (a-Si, LTPS or oxides). • PI: Strong absorption in the visible spectra  unsuitable for bottom emission and transparent displays. • High CTE (PES) • High cost (>glass for display- grade PI) • Compatible with some or all TFT process temperatures (with some adjustments) • Low CTE (PI) Pros Cons ©2016 | www.yole.fr | Organic TFT
  • 15. 15 TFT AND OLED PIXEL STRUCTURES • There are variousTFT architectures: Example of TFTs fabrication steps: (a) gate definition, (b) gate-insulator deposition, (c) channel layer deposition (d) source/drain (S/D) definition, (e) passivation (source: Transparent Oxide Semiconductors for Advanced Display Applications, Arokia Nathan, Information Display, Jan 2013) Gate Substrate Gate Insulator ChannelSource Drain Gate Insulator Substrate Gate Insulator DrainChannelSource Gate Top Gate TFT Bottom Gate TFT • In “Bottom Emission” display structures, the light generated by the pixel is emitted toward the TFT. In this configurations, the TFT array therefore blocks some of the light or reduces the active surface of the pixel. It is therefore important to minimize the size of the TFT circuitry to increase display brightness.

  • 17. 17 DISPLAY MARKET: PANEL CONSUMPTION THROUGH 2022 • We estimate that the demand for TFT display panels will reach XXX Millions of m2 in 2016 and increase to XXXM of m2 by 2022. • Demand is strongly dominated by large displays: television and computer monitors. Smartphones come third despite their smaller area thanks to very high volumes. Together, those 3 segments represent > XX% of the total. • Wearables (represented by the categories “smartwatches” and “other wearable”) as well as embedded displays (automotive etc…) are expect to experience fast growth but remain a small fraction of about XX% of the total TFT market. • Note that “other wearable” category is a catch all category to account for wearable devices that are not smartwatches. Those include wristband, fitness trackers etc… and possibly new applications. ©2016 | www.yole.fr | Organic TFT

  • 19. 19 OTFT PERFORMANCE: HYPEVERSUS REALITY. • Communication of OTFT performance is often focused on mobility. But other parameters such as homogeneity, reliability, manufacturability, cost of ownership etc.. are equally important. • State of the art molecular engineering allows to deliver on all those criteria: all the building blocks are ready in the lab. But bringing it all together is another challenge. • Ultimately, the best OSC for mass production of devices might not be the one with the highest electrical performance but rather, one designed for the application that offers the best compromise on those requirements. • Material suppliers and OTFT manufacturers will eventually develop increasingly versatile process and material toolboxes allowing them to adjust the materials and the TFT process to each application.

  • 20. 20 SMALL MOLECULES VS POLYMERS • While mobility is a critical parameter, reproducibility and processability are equally important. • Small molecules tend to be ahead in term of performance but crystallization is difficult to control. This creates homogeneity and reproducibility issues. • Amorphous and polymer materials have a wider process window but lag in term of performance. Small molecule and polymer each have their pros and cons. But materials and processes have improved dramatically for both over the last few years.

  • 21. 21 PIXEL DENSITY AND CHANNEL LENGTH • As the resolution of mobile displays increases, the available surface for the TFT circuit decreases. In the last 2 generations of Samsung’s Galaxy S6 and S7 phones (discussed below), we estimate that the 5 transistors + 2 capacitor + data lines required to drive each subpixel must fit in a ~ XX x XX µm2 box (Samsung uses a top emission structure so the circuit can occupy the entire pixel area). This estimate was confirmed by our sister company “System+ Consulting” which conducted a tear down analysis of the Galaxy S6 (next pages) XX µm The human eye is most sensitive to green, especially for high resolution luminance information. The Galaxy displays exploit this feature and use a pentile diamond subpixel arrangement in which green pixels are interleaved with red and blue pixels: • The green subpixels are mapped to input pixels on a one to one basis, reconstructing the luminance signal to the display resolution (1440 x 2560). The red and blue subpixels are subsampled, reconstructing the chromatic signal at a lower resolution. • The Red, Green, and Blue sub-pixels have different sizes. The blue ones are the largest because of the low material efficiency and human eye response sensitivity.

  • 23. 23 BILL OF MATERIAL • The level of complexity in the molecular engineering and manufacturing process of the OSC is not too different from that of OLED materials such as the ETL, HTL etc... As volume increase, the cost of the OSC material could decrease toward similar levels (<$XX/g) • The cost per gram of the gate dielectric is lower than that of the OSC but offers less opportunity for cost reduction. Long term cost will depend on the chemistry and the level of functionalities put into them (crosslinked, photo-patternable etc…). • The binder material used in the ink formulation is not highly engineered and generally low cost, to the exception of companies that use a low performance polymer semiconductor. • We estimate that the BOM for OTFT could drop by 40 to 50% over the next 3-5 years and a factor of 2.5 to 3x if adoption rate enable high volumes and economies of scale. Ultimately, transition to an additive manufacturing process (inkjet or other printing technology) could further reduce the cost.

  • 24. 24 OSC AND OGI REVENUE FORECAST THROUGH 2022 • The base scenario shows that under the current technology roadmap and status of the industry, OTFT will remain a niche market. The market for OSC materials remains small and can’t support more than a couple of companies able to capture the most value by selling all materials in the stack. • Under this scenario, it is not clear if the industry will reach a critical mass to allow a massive take off. Will material suppliers and panel makers continue to invest to enable a larger market? • Our “breakthrough” scenarios illustrate how further technology advancements could enable a much larger market. The underlying assumption for those scenario are: • The “Printing scenario” accelerates penetration of AMOLED TVs versus LCD by reducing manufacturing cost. It provides incentive for panel makers to accelerate development of printable TFTs. This enables OTFT penetration in TVs • The “Vertical TFT scenario” accelerates OTFT performance and increases OSC consumption per unit surface. To create a significant market, a technology breakthrough, or an acceleration of the current OTFT roadmap is required. ©2016 | www.yole.fr | Organic TFT

  • 43. When trying to build a flexible display panel, the Thin Film Transistor (TFT) matrix is one of the most challenging and fragile functional layers. Interest in OTFT emerged in the mid-2000s when mobility reached values similar to amorphous silicon (a-Si), the dominant display backplane technology. This triggered a flurry of activity at leading display manufacturers, and prototypes rapidly emerged. Besides fast-improving electrical performance, OTFT’s intrinsic flexibility made the technology ideal for the realization of flexible displays. In 2007, the first ever flexible AMOLED panel was demonstrated by Sony and featured an organic TFT. However, interest waned as performance and homogeneity issues persisted, and other TFT technologies like LTPS and metal oxide emerged. Nevertheless, organic semiconductor companies kept perfecting their molecules and ink formulations, gaining a better understanding of the interaction between the materials, the transistor structure, and the manufacturing process. Consequently, performance in the lab improved by another order of magnitude. Combined with the explosive growth of flexible displays and the promise of a cost-efficient, solution-based manufacturing process, interest in OTFT has renewed. Panel makers remain cautious, but a handful in Taiwan and China are currently attempting to retrofit older Gen 2.5 - 4.5 fabs with OTFT. These first attempts to move OTFT into mass production will be critical for the technology’s future. Failure in these initial industrialization attempts could be fatal for the OTFT industry, or, at the very least, set it back many years. However, if OTFT proves that it can be mass produced and enables panel makers to revive those obsolete fabs with high-margin flexible displays, there are no fundamental barriers prohibiting the technology from being quickly scaled up to fabs Gen 8 or above, and possibly challenge the vast market for traditional a-Si based panels like LCD TV, monitors, etc. In the long-term, because they are inherently solution-processable, OTFTs are also an ideal backplane candidate for additive manufacturing and fully printed displays. This report presents a detailed review of flexible displays, including an analysis of technical challenges (frontplane, backplane, substrates), manufacturing status, key players, and technologies. This report also provides a complete review of established TFT backplane technologies. ORGANIC THIN FILM TRANSISTOR (OTFT) 2016: FLEXIBLE DISPLAYS AND OTHER APPLICATIONS Market & Technology report - October 2016 ORGANIC TFTs ARE ENTERING THE FAB BY THE BACK DOOR Are OTFTs ready to disrupt the display industry and enable fully-flexible devices? KEY FEATURES OF THE REPORT Get the sample of the report on www.i-Micronews.com • Flexible displays: benefits, challenges, roadmap, technologies (frontplanes, backplanes and substrates) • Backplanes for flexible displays: a-Si, LTPS, metal-oxide, OTFT • OTFT performance roadmap, challenges, cost of ownership, progress toward the fab, SWOT analysis • OTFT application roadmaps: detailed segment analysis (wearable, mobile, laptops tablets, TV monitors, automotive embedded displays, digital signage, e-readers) • OTFT materials volume and revenue forecast through 2022 OBJECTIVES OF THE REPORT This report provides a full analysis of the status and prospects for organic thin film transistors (OTFT) for displays and other applications: • Main challenges for producing flexible displays • TFT backplanes: technology review, capacity analysis, potential for flexible displays • OTFTs: technology roadmap, SWOT analysis, manufacturing challenges, OTFT in the fab • Application: pros and cons of OTFT for each segment, application roadmap, penetration forecast • 2017 - 2022 forecast: total OTFT surface (m2 ), channel and gate dielectric volumes (kg) and revenue (US$M), ASP forecast (Yole Développement, October 2016) TFT performance and flexibility Mobility (cm2/vs) Bending radius (mm) 1 0.1 10 100 0.1110100 True flexibilityCurved Bendable / Conformable Foldable / Rollable Medical sensors X-Ray Imager 0.01 EPD Mid-resolution Wearable displays (300 ppi) Metal Oxide LTPS OTFT 2016 lab result / Mid term fab goal (5 years) OTFT 2016 “Fab-level” performance a-Si Possible extension of oxide flexibility? ORGANIC SEMICONDUCTOR (OSC) SUPPLIERS HAVE MORPHED INTO FULL SOLUTION PROVIDERS The display panel industry tends to require high capex in order to generate fairly low margins. Companies are therefore relatively conservative when it comes to switching to new TFT. They look for technologies that: • Are highly compatible with existing process and equipment. • Generate higher margins than the incumbent technology by allowing higher added-value products (OLED, flexible displays) and/or reduced manufacturing costs.
  • 44. ORGANIC THIN FILM TRANSISTOR (OTFT) 2016: FLEXIBLE DISPLAYS AND OTHER APPLICATIONS ORGANIC TFTs ARE SEARCHING FOR THEIR FIRST KILLER APPLICATION OTFT mobility in the lab now exceeds 10 cm2 /vs, with record values up to 40 cm2 /vs, theoretically good enough to drive all display types and compete with all TFT technologies. But while these results are a good indication of the progress made with organic semiconductors, they have been obtained in conditions far from practical in actual fabs and commercial devices. Current realistic fab-level performance stands in the range of 1 - 2 cm2 /vs, with a credible path toward 3 - 5 cm2 /vs over the next 18 months - 3 years, and possibly 10 cm2 /vs and above within 5 - 10 years. At the current level, OTFTs are already superior to the dominant a-Si platform and enable a whole new range of very cost-effective, flexible electrophoretic and LCD displays with a bending radius as low as 30 mm. Not exactly “foldable”, but flexible enough to conform to curved surfaces in all application types, such as embedded displays in automotive, consumer appliances, and digital signage. These displays also feature reduced weight and thickness and improved ruggedness from their plastic-based construction. The aforementioned applications could become a stepping stone for OTFT, allowing panel makers to validate and optimize the technology in their Gen 2.5 - 4.5 fabs and prepare to scale up to larger substrates while material suppliers fine-tune their molecules to reach performance sufficient to drive mid-pixel density OLEDs. This would unlock a whole new range of applications by enabling cost-effective manufacturing of low power consumption, fully flexible displays for wearable and mobile applications. From there, it remains to be seen if performance will further improve in order to serve the high-end OLED market, or if OTFT can deliver on its cost- effectiveness promises. If so, OTFT could become a credible alternative to a-Si in the manufacture of large LCD panels, enabling higher resolution and higher brightness - features that are critical to the UHD TV market’s emergence. This report focuses on OTFT display applications and the associated market volume for the period 2016 – 2022, broken down in 13 segments. Moreover, this report provides an analysis of market volume and revenue for organic semiconductors (OSC) and gate insulators (i.e.: OGI). Our forecasts have been developed on the basis of different scenarios, taking into account potential future technology breakthroughs (i.e. printing process, vertical transistors).

Conformable OLCD in wearable embeddable OLED TV FHD to UHD Mobile LCD FHD to UHD Organic semiconductor suppliers have realized that success means offering turnkey solutions comprising the full material stack, and processes as compatible as possible with old a-Si equipment. This means photo- patternable, cross-linkable materials that can be processed with existing broadband lithography tools already present in the fab, and which can withstand traditional patterning and etching techniques. In the short-term, this puts significant stress on companies that started as small teams of organic materials experts. These companies now must access additional capital and set up partnerships in order to access fab equipment and develop a full process toolbox. However, in the long-term this will permit surviving companies to capture more added-value than by simply supplying the channel material. This report presents a detailed analysis of OTFT, including benefits, challenges, performance status, and roadmaps. Additionally, this report provides an analysis of OTFT manufacturing (technologies, structure, etc.), cost of ownership, and competitive landscape (i.e. supply chain, OSC suppliers). Company profiles for key players are also included.
