Abstract
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.
