Can the TFT display turn organic?

Smart phones, televisions, notebooks, and computer monitors are the three big markets for TFT displays. Market researcher Yole estimates the global demand for TFT display panels across all technologies will reach 188 million of m2 in 2016 and increase to 238 million of m2 by 2022. Is there a chance for organic TFT LCD displays replacing the present TFT LCD display panels.

Organic TFT transistor based displays are made only in prototypes, they are not really made in commercial volumes or successful to make in commercial volumes.

The market researcher yole development has done a latest study on this product and its come out with its latest market analysis findings; below are the findings yole has shared in its latest release:

Multiple panel makers are currently attempting to unroll OTFT into older fabs. If successful, this would boost the credibility of the technology and the willingness of panel makers to invest and scale up. On the other hand, failure in the current attempts could be a fatal blow for the industry or at least, push back adoption by another 5 years. Indeed panel makers would temporarily pull the plug on their industrialization effort and send OTFT back to the lab until all the technology bricks are ready for true flexibility or other, non-display applications emerge.

OSC suppliers and OTFT makers have made significant advances in term of molecule performance, ink formulations and accompanying materials. Progresses have also been made in TFT design, processes and manufacturing technologies. This has led to improved OTFT performance and manufacturability and compatibility with existing equipment. Plastic Logic was the first to enter mass production of flexible EPD based on OTFT backplanes in 2009.

A wide variety of OTFT-based devices have been demonstrated: AMOLED , EPD, LCD displays as well as X-Ray imagers, fingerprint readers, and various types of sensors have been fabricated. In addition, multiple bricks of technology have been demonstrated for various types of electronics: inverters, ring oscillators, gate arrays, NANDs Moreover most of the leading display makers are working on OTFT: LG, Sony, BOE, AUO, Chunghwa Picture Tube, etc. Many display makers have demonstrated a wide range of prototypes but none have released any commercial, mass produced products. The only notable exception is Plastic Logic, but the commercial success of its flexible EPD displays has so far remained fairly limited.

In order to enable this market, OSC/OTFT makers business model and marketing efforts have evolved from focusing on the commercialization of OSC molecules to offering full material packages and complete, fab-ready technology and process toolboxes. Full toolkits are now available that include all essential materials and processes to enable OTFT manufacturing with existing equipment.

Dr Eric Virey, Senior Technology & Market Analyst at Yole said,"Indeed the market demand is strongly dominated by large displays such as television and computer monitors. Smartphones come third despite their smaller area thanks to very high volumes. Together, those 3 segments represent more than 90% of the total comments." Dr Eric Virey.

Wearables mostly represented by categories and they are: smartwatches and other wearable as well as embedded displays automotive and more, are expected to experience fast growth but remain a small fraction of about 1% of the total TFT market in term of surface.

OTFT first commercial products could emerge in the following applications:
E-papers (e-readers and other applications such as signage, smart tags, etc.) Embedded displays: automotive, industrial, etc

Yole's analysts developed two scenarios based on OTFT adoption rates in each of the major display segments. Under Yole's base scenario, there is limited to no adoption in larger displays such as laptops, monitors and TV. Because those large display applications are strongly dominating the market in term of total TFT area, the global OTFT adoption rate across all applications comes to slightly above 1.3% in term of total TFT backplane surface.

In an aggressive scenario enabled by various OTFT technology breakthroughs detailed in the report, TV would become the single largest OTFT backplane segment as organic semiconductors would compete efficiently against a-Si.

Due to the sheer size of the TV market, even a low OTFT penetration rate would significantly increase the size of the OSC and OGI markets.

"Our aggressive scenario illustrates how commitment from both panel makers and materials suppliers could unlock the full potential of the technology analyzes Dr Eric Virey."
