Flexible AMOLED / Ch
Flexible AMOLED, Color of Ch-LCD production soon, is bound to cause electrophoresis of existing mainstream is not a small impact on the face of soft color AMOLED with the rise of Ch-LCD, flat-panel makers support the development of electrophoresis of soft OTFT as if ready to fly, can be expected in the next three electronic-paper technology to the mainstream of the struggle intensified.
As the panel maker Samsung (Samsung), LG Display (LGD), ITRI and other domestic painstaking hard work, the flexible active matrix organic light emitting diode (AMOLED) rapid technological progress, will be the cholesteric (Ch -LCD) and micro-electromechanical systems (MEMS) display technology, the star of another electronic paper technology, the current dominance of the electrophoretic display (EPD) technology formed no small threat. Which, EPD support how to manufacturers of soft AMOLED with Ch-LCD, MEMS pincer e-paper market to stand, much industry attention.
Back to help were sped up the commercialization of flexible AMOLED
Flexible AMOLED technology advances, has become the electrophoresis, Ch-LCD and MEMS rival not to be underestimated. To advance the commercialization schedule, PVI, AU Optronics, LG and other flat-panel makers have plans to mass production in 2010 in the second half of soft thin film transistor (TFT) backplane, which is to begin the commercialization of soft AMOLED paving.
ITRI center panel image display technology integration technology mere lists revealed long-Jane Lee, ITRI has domestic PVI, such as panel makers AUO and technical cooperation, the second half of 2010 will be the beginning of soft TFT backplane capacity production, which is essential for development of flexible AMOLED key components of electronic paper is a major technical challenge lies 80% of the initial yield will be watching the other, the board continued to improve the reliability of soft under the OLED can also be hope to accelerate the pace of commercialization of flexible AMOLED. It is reported that, in order to step up card digital market, the new Chi Mei and AU Optronics has acquired a large number of AMOLED patented technology.
Taiwan panel makers not to be ahead of us, South Korea's Samsung and LG Display has also begun development of flexible TFT backplane, which LG Display will display the backplane for electrophoresis by the Korean panel makers has always been a strong view of style the future will be Taiwan's flat panel industry rivals can not be ignored.
The ultimate goal of the next soft AMOLED is flexible polyimide (PI) plastic coating on the glass substrate directly, and then on PI substrate made of soft plastic TFT, and in the manufacture of OLED and TFT top of EPD, in order to achieve continuous Roll (R2R) process, to reduce manufacturing costs to achieve the purpose. Li Zheng pointed out, TFT Flexible process to reach a temperature below 350 ? process, and a breakthrough soft PI substrate the stress problem, it is best to design a temperature of up to 300 ? soft PI substrates to meet the requirements.
Compared with conventional TFT LCD, AMOLED is self-luminous body, even in the sun can still be read without backlight and can achieve high color saturation of the advantages; and electrophoresis, Ch-LCD display technology, compared with MEMS, the reaction speed, with color saturation, dynamic images can be realized, however, not soft comfort AMOLED read as electrophoresis, Ch-LCD, and the like paper, electronic paper technology, market participants questioned the market to enter the e-book reader competitiveness may be limited, in addition, life expectancy and costs also need to overcome technical bottlenecks.
Li Zheng of the view that the end consumer in the future use of electronic paper watch digital content for a long time, but watching video of the time may be too much to read, so electrophoresis and AMOLED manufacturers will have their own support.
Although electrophoresis in black and white e-book reader market is achieving first mover advantage, but AMOLED, Ch-LCD technology such as the rise of, the oppression of their living space is bound to be expected that future AMOLED and other electronic paper technology area will be separated, but Jane Lee in the forecast, AMOLED broader scope, the market is expected to become the largest electronic paper display technology.
Optimistic about the potential of soft AMOLED, plus panel industry will trend towards the bigger the evolution of some segments with competitors, various manufacturers will certainly committed to enhancing product differentiation. Domestic HannStar Display, PVI, CPT, AU Optronics, Chi Mei h ave rushing new soft AMOLED technology research and development, in addition to accelerating the commercialization of flexible AMOLED reached, will help to expand the flexible AMOLED market.
Li Zheng stressed that domestic and foreign investment with flexible AMOLED technology is the growing number of firms, flexible AMOLED mass production of time than generally expected five years much faster.
The other hand, Fujitsu (Fujitsu), Samsung, Kent Display, etc. painstaking research and development industry, the color of Ch-LCD has reached commercialization, in order to prevent foreign monopoly market opportunities, Taiwan panel makers are catching up quickly, and gradually overcoming AM TFT backplane and on board display technology combined with stifling media, mass production expected in 2011.
