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.
