Flexible display further super bend OLED appeared

Taiwan in the development of flexible display further, Taiwan 18 issued a variety of flexible display technology, the active organic motor 1 4.1 inch display (AM OLED), the plastic substrate, the thickness of only 0.2 cm, the bending radius of less than 1.5 cm, ITRI display center director Cheng Zhanglin said that the application of the development of the future have the opportunity to roll and full color, scroll type display screen makes the dream come true.

Caption: ITRI launched 10.4 inch single color cholesteric liquid crystal display. 18, ITRI in 2008 green display technology exchange ", published a variety of new flexible display technology, in addition to the ultra curved active OLED latest panel, in addition to the scroll bar type (Roll to Roll) the production of cholesterol liquid crystal, 10.4 inch full-color single color cholesteric liquid crystal display, and 6 inches. The active color electrowetting display (ELectrowetting Display; EWD).

Cheng Zhanglin said that the display application trend and development direction, the global panel manufacturers to develop a new generation of technology, nothing more than a large area and continuous rolling strip production, lower cost, consistent with the requirements of environmental protection, energy saving and non-toxic and light is not easy to damage, and the flexible display technology just meets all the above trend is more consistent with the all kinds of products in the future life of the demand situation.

Among them, in the active OLED products can be highly curved, the Institute launched a 4.1 inch panel, the main focus of development lies in the realization of OLED materials can be produced on a plastic substrate, and OLED soft panel in bending at the same time, still can display the animation image. Cheng Zhanglin said, this technology panel factory just now in the production process technology and equipment, although the test is single product, but in the end the future panel factory can use color collocation materials, soft substrate manufacturing technology research institute, is expected to achieve the soft OLED and the scroll bar display further into production stage.

In the aspect of Cheng Zhanglin said that the cholesteric liquid crystal, cholesteric liquid crystal technology from Kodak Research Institute (Kodak), in this regard, the patent technology, product diversification, it is first in the world, in which roll to roll continuous production process, the width of breakthrough in the global record of 3.5 inches, ITRI has production width of 9.6 inches (about 24cm) products, using dual color display, its applications include digital signage, large stores situated wall and so on, Cheng Zhanglin said, this is the introduction of technology, the most mature, most have the opportunity to quickly guide production technology, at present also is in talks with a number of manufacturers in the production license.

In addition a cholesteric liquid crystal is aimed at the market topic of product e-book application Cheng Zhanglin said, relative to the market of electronic products, such as Sony, Amazon (Amazon) products are introduced by electrophoresis (EP) technology, Cheng Lin Zhang said, electrophoresis technology such as E-ink the current bottleneck is colored, recently Samsung Electronics (including Samsung Electronics) also announced that the choice of cholesteric liquid crystal for the production of color books, in this regard, ITRI has been leading a few steps to launch 10.4 inch monolayer color cholesteric liquid crystal display, in addition to the bending, folding, light and other flexible display characteristics, brightness is greatly improved, the reflectivity is increased from 16% to 30%, resolution QVGA, the future will further increase to SVGA.
