Top-emitting OLED display having transparent touch panel
First Claim
1. A top-emitting organic light emitting diode (OLED) display having a transparent touch panel, comprising:
- a substrate;
an upper cover plate;
an OLED device stacked on the substrate;
a capacitive touch device stacked on a surface of the upper cover plate; and
a sealant layer surrounding the OLED device;
wherein the OLED device is enclosed sealed by the substrate, the sealant layer, and the upper cover plate, and the upper cover plate is attached to the substrate by the sealant layer; and
wherein the capacitive touch device comprises a first transparent conductive layer, an isolating layer and a second transparent conductive layer sequentially formed on a lower surface of the upper cover plate, and the first transparent conductive layer and the second transparent conductive layer form a capacitor,wherein the capacitive touch device further comprises an electromagnetic shielding layer stacked on the second transparent conductive layer, said electromagnetic shielding layer effectively reduces the electromagnetic interfering between the OLED display and the capacitive touch device; and
wherein the electromagnetic shielding layer comprises a polymer insulating layer and a transparent conductive layer.

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.
