German scientists launched the world's first OLED touch screen

Researchers at the Fraunhofer Institute in Germany (Fraunhofer) invented the world's first touch screen using a OLED flat light source, which will be shown at this year's 2008 plastic electronics show in.

It is reported that, OLED lighting is a promising future lighting solutions, and the creation of a history of lighting, to overcome the shortcomings of point light sources, such as light bulbs, LED, etc..

In addition to the advantages of flat lighting, OLED lighting and color variable, transparent and flexible advantages. Since OLED is a cold light source, touch control is safe.

"Touch screen technology gives people a new feeling, just like magic, the finger can only be a little light can be turned on, the Institute of organic materials and systems business director J RG AmELung said.

The new breakthrough is that the touch screen does not require additional hardware, OLED itself can read the touch signal. Turn on the light and adjust the brightness can be easily controlled by hand to overcome the shortcomings of the traditional controller. In general, to achieve the touch function needs to be on the top of the device with the additional aluminum foil.

According to the Institute, this OLED touch function can reduce costs without compromising OLED efficiency.
