New breath with OLED

OLED has brought a very different and significant impact in the new communication technology through its unique characteristic in mobile industry. We can tak apple iphone for the closest example on how oled works, the only tricks in Iphone is that they use capacitive touch screen.

The different is that, a top-emitting OLED display having a transparent touch panel includes a substrate, an upper cover plate, an OLED display device, a capacitive touch device and a sealant layer. The OLED device is stacked on the substrate, the capacitive touch device is stacked on the upper cover plate, and the sealant layer combines the substrate and the upper cover plate such that the OLED device and the capacitive touch device are enclosed between the substrate and the upper cover plate. The capacitive touch device includes a first transparent conductive layer, an isolating layer, a second transparent conductive layer and an electromagnetic shielding layer sequentially formed on the upper cover plate. The electromagnetic shielding layer can effectively reduce the electromagnetic interfering between the OLED device and the capacitive touch device. Means that, the OLED is having more transparent touch screen than capacitive or resistive touch screen.
