LED research and Innovation ITRI shows the latest display technology

At the 2010 Taipei International Optoelectronics week, to find new "life" / "bright, open" as "watch new world" as the theme, with innovative research results and the most popular LED display technology, with the virtual environment, interesting interactive experience, depicting the future use of new technology situation. The exhibits on display, including the ability to improve the luminous efficiency of 15% of the magnetic energy LED, can bend the AC LED lamp, the color of the electronic paper, the future of the new electronic tools and other items, such as the label of the 48 items of the exhibition, and so on.

This year in the LED application and innovation institute innovation have repeatedly luminous efficiency. Surprisingly, the combination of magnets and LED, innovative use of magnetic field to change the LED current, prompting a significant increase in luminous efficiency of 15% LED. Different from the existing LED technology, only pay attention to the improvement of optical loss and epitaxial crystallization, ITRI to overcome the traditional high brightness LED current uneven dispersion, the luminous efficiency is poor and the problem of uneven brightness LED.

The magnetic energy into the way of the uniform current distribution, current limited to ITRI successfully change the electrode below the light mode, make the regional light the highest efficiency is no longer covered metal electrode, LED can uniformly disperse the light efficiency, reducing the cost of light power. The technology has completed the global patent layout, is expected to add a new weapon for the domestic LED industry, enhance competitive advantage.

Consider flexible lighting is a new trend in the future, in the application of ITRI won the 2008 Best Global Technology Award (R&D Award 100) AC LED technology extension developed original lighting applications: 14 inch flexible AC LED lamp. This product is soft, thin, bendable, and no transformer device LED lighting source, the future can be used in flexible lighting, lighting, lighting, decoration, creative context modeling design, expand the market for LED lighting applications.

Flexible color AMOLED electronic label,

ITRI has developed color flexible AMOLED display, only a thin layer of 100 microns thick, resolution 66dpi, bending radius can reach 5 cm below the curl at the same time, color film animation continues to play a. This soft display, the screen can be repeated after 2500 times, but the animation function is not affected. The future can be applied in the development of e-book, e-book reading, I can enjoy the film animation.

Jia special label is electronic paper display material preliminary extension application, at present only a small area, there is no application in large area appears. Flash electronic label on cholesteric liquid crystal technology research institute collocation segment is driven, can reach A4 size, selling the goods can be marked content, price and promotion information, especially for fast flashing in a particular scene, can attract audience attention, immediate promotion.

And electronic paper labels such as long as through the wireless transmission mode that can be sold information no longer need to replace the artificial replacement product nameplate, is a large store new weapon advertising promotional instant, the future can be used in retail, supermarkets, hypermarkets, station and exhibition field location.

Regional 2D/3D switch, solar power generation energy-saving windows

3D stereo images at the same time, but we do not know the text is a puzzling problem; therefore ITRI newly developed regional 2D/3D switching technology, which can be used in a full screen, select 3D display area location or size, 2D/3D switching function, the same text definition 2D with high resolution screen, at the same time in the 3D display area and can display stereo image vivid. Suitable for the network, games, advertising images and videos, such as the presentation of three-dimensional multimedia images.

In addition ITRI also exhibited a solar power generation energy-saving window, the light diffusion layer specially designed evenly efficiency solar light by the light diffusion layer on light guide layer, a photoconductive layer and the air interface reflection, the sun light can be reflected after collected by solar module around the solar maximum around 50% of the solar energy battery conduction to the window, can provide DC power for use of 3C appliances, energy conversion rate was up to 8%.

Compared to the perspective of silicon thin film solar cell and the perspective of dye-sensitized solar cell, this technology has a high transmittance (20~50%), high stability and high color fidelity. In addition, due to the use of PC diffusion type substrate, so that in addition to the general characteristics of the module with a transparent window, and has good toughness, become a bullet proof glass structure, strengthen the protection of home security. Energy saving power generation and bulletproof safety window, will become the standard of green building.

Energy-saving wisdom shutters, color books, soft pressure sensor

Electrowetting liquid crystal ITRI development (ELectrowetting Display, EWD) green energy-saving wisdom modulation window, because the liquid crystal ink and water immiscible, quick reaction, conversion time is about 12~13 MS, and collocation RGB inkjet process, suitable for use as the window display color transform. In addition, minimal power consumption, only a low driving voltage to 20 volts below, collocation of solar independent power supply, without external power supply, can achieve the effect of energy saving, the future can be used in color and home building windows.

In addition ITRI has developed a flexible 6 inch color AMOLED display, on the screen of 0.2 cm thin bending fold, color film, animation continued playing, bending radius can reach 5 cm below, beyond the other international flexible display bending performance, brightness up to 150nits.
