可弯曲显示器将于2017年上市

LG Display近日展示一款可弯曲的大尺寸(18吋)显示器原型，它可以被卷成一个直径3公分的滚动条，而无损任何显示功能。此外，还可以把这款透明的显示器打开来挂在墙上、平放在桌上，或是当成一幅画裱在传统画框中。虽然目前只展示了原型产品，但LG预期，一款具有更高透光率的60吋版本将在2017年以前上市。

“LG 持续展示在软性基板上生产显示器的能力，致力于导入商用化更是该公司的重点计划，”NPD DisplaySearch总裁Paul Semenza表示，”再过几年，我们就能看到小尺寸的可弯曲显示器出现，例如应用在智能手表屏幕上，但这些都只是在弯曲玻璃上盖后面安装一层软性基板， 至于想真正实现在任何时间可弯曲成任何形状的话，还需要一段时间。” OLED 显示器不需要背光，而且采用在透明基板上沈积的方式生产，可悬浮空中显示原理图和其他图形。LG展示其悬浮显示技术，以证实该公司已掌握了任何尺寸的可卷 曲透明显示器所需要的基本技术。然而，目前在实现商用化之路仍存在明显障碍，特别是无法保护 OLED 免于可能损坏显示器的湿度与空气。

“预 计在2020年以前，主动式OLED的营收可望超过230亿美元，其中大部分都来自于具有固定弯曲角度的智能手表与手机，”Semenza表示，“主要的原因在于生产上的挑战。或许目前已到把固定弯曲某个角度的显示器封装在玻璃或金属中，以保护其免于环境的损坏，但还没有一款背板够灵活且可靠，足以避免对 OLED造成损害。” 软性显示器可以为观众创造出一个身临其境的环绕体验──类似于 IMAX 电影院的体验。屏幕弯曲技术还可以让移动设备变得更易于携带，而且还可以提供像蓝图般易于运送的次屏幕。 这 款18吋的可卷曲显示器原型采用1200x800的配置以及30R的曲率半径，提供不到1百万像素的分辨率，能够整个卷曲起来放进一个直径约1.2吋的 滚动条中，而仍正常显示而无损于任何功能。LG表示，未来还将致力于将屏幕尺寸增加到60吋、曲率半径提高到50R，实现更大尺寸的可卷曲显示器。

相较于LCD约10%的典型透光率，LG的可弯曲显示器可实现高达30%的透光率。

LG显示器的透明背板还能实现悬浮应用──在透明的聚酰亚胺(PI)背板上显示战略性的数据，大幅减少显示器的厚度，而使其更具有可挠性。除了像科幻小说中用于显示战情以外，其他商业应用还包括可在冰箱门上看到里面冰着哪些食物，以及有关冰箱内温度或甚至是广告等信息。 根据LG表示，透过使用特殊的电路组件与薄膜组件，该公司开发的显示器可实现30%的透光率(LCD透光率为10%)以及降低2%的雾化度。 本文授权编译自EE Times，版权所有，谢绝转载 编译：Susan Hong 参考英文原文：Flexible Displays Going Commercial，by R. Colin Johnson

{pagination} Flexible Displays Going Commercial R. Colin Johnson PORTLAND, Ore. -- LG is first out of the gate with a completely flexible large-scale (18-inch) display that can be rolled up for transport into a three-centimeter (1.2-inch) scroll. The transparent display could be unfurled and hung on the wall, laid on a tabletop, or mounted in a conventional frame. Though it is only a demonstration prototype, LG predicted that it will have a 60-inch version with even higher transmittance on the market by 2017. The 18-inch flexible OLED display can be rolled up for storage or transport. (Source: LG) "LG has demonstrated the ability to produce displays on flexible substrates for some time, working on getting that to commercialization is quite a project," Paul Semenza, president of NPD DisplaySearch, told EE Times. "We will start seeing smaller flexible displays over the next couple of years, such as those in a smart watch, but they will just be flexible one time when put behind a curved glass cover, but to have them flexible in any shape at any time is some time off." The organic light emitting diode (OLED) display needs no backlight and, being deposited on a transparent substrate, could display schematics and other graphics in mid-air. LG demonstrated its mid-air display in order to prove that it had mastered the basic technologies needed for rollable transparent displays of any size, but there are still significant hurdles to commercialization -- mainly the inability to protect the OLED from moisture and oxygen, both of which destroy the display. A working 18-inch flexible OLED display can be flexed into a three-centimeter (1.2-inch) scroll. (Source: LG) "We believe that, by 2020, active OLED revenue could be just over $23 billion, most of which will come from smartwatches and mobile phones that are flexed and fixed," Semenza told us. "And the reason for that is the production challenge. You can encapsulate a curved and fixed display in glass and metal to protect it from the environment, but no backplanes yet exist that are flexible yet reliably prevent damage to OLEDs." Flexible displays can create a wraparound immersive experience for the viewer -- similar to the Imax theater experience. Curved screen technology can also make mobile devices easier to carry, and it could provide auxiliary screens that are as easy to transport as a blueprint. The prototype 18-inch display had just short of 1 million pixels in a 1,200-by-800 configuration with a curvature radius of 30R, allowing it to be rolled into about a scroll a little over an inch without damage and while still working. For the future, LG is trying to increase the screen size to 60 inches while increasing its curvature radius to 50R or a scroll a little less than two inches. Unlike LCDs, whose typical transmittance is around 10%, LG's device offers a transmittance of 30%. (Source: LG) The transparent backplane for LG's display will allow mid-air applications -- for displaying tactical data on its transparent polyimide backplane, which minimizes the thickness of the display and makes it more flexible. Commercial applications, besides sci-fi like tactical displays, could be for refrigerator doors, where you could see the food inside, along with information such as temperature or even advertisements. LG says that, by using special circuit devices and film components, it achieved 30% transmittance (compared with 10% for LCDs) and lowered haze to 2%.
