  • Patent number: 9640590
    Abstract: An organic light-emitting diode (OLED) display and fabrication method thereof are provided. The OLED display includes an organic light-emitting layer comprising a plurality of primary color regions and a plurality of mixed color regions, wherein the primary color regions and the mixed color regions have the same light emitting direction. A color shift prevention layer is disposed above or under the organic light-emitting layer, the color shift prevention layer comprising a plurality of opaque patterns disposed on the light emitting direction of the corresponding mixed color regions. The color shift prevention layer incorporated in the OLED display is able to block the mixed light emitted from the mixed color regions of the organic light-emitting layer. Therefore, the color shift problem can be solved.

  • Publication number: 20150069364
    Abstract: An organic light-emitting diode display and method of manufacturing the same are provided in the present invention. The organic light-emitting diode display includes an anode layer and a cathode layer opposite to and spaced apart from each other, an organic light-emitting layer disposed between the anode layer and the cathode layer, wherein the organic light-emitting layer includes primary color regions and mixed color regions, and a color deviation protective layer disposed between the anode layer and the organic light-emitting layer or between the organic light-emitting layer and the cathode layer, and the color deviation protective layer is provided with insulating patterns corresponding to the mixed color regions to prevent light generation from the mixed color regions. The manufacturing method features the step of disposing a color deviation protective layer to prevent light generation from the mixed color regions of the organic light-emitting layer and solve conventional color deviation issue.
