Problems solved by technology
During the evaporation process, the organic material will remain on the mask plate near the opening, and the residual organic material has weight. Over time, the mask plate will be deformed, resulting in a change in the shape of the opening of the mask plate, which in turn will make the mask plate The openings cannot be precisely aligned, resulting in a mixed color area on the organic material layer, that is, overlapping of different colors in a certain pixel area, resulting in color deviation

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.
Description
technical field [0001] The present invention relates to a display, in particular to an organic light-emitting diode display (organic light-emitting diode, OLED display) display and a manufacturing method thereof. Background technique [0002] Organic light-emitting diode (OLED) display has always been considered by the industry as one of the most competitive next-generation display technologies. Its advantages include self-illumination without a backlight module and fast response , Low operating voltage. [0003] A standard OLED display has the characteristic of self-luminescence, and adopts an organic material layer composed of organic materials. When an electric current passes through the organic material layer, the organic material in the organic material layer will emit light. With different organic materials, OLED displays can emit light of different colors to meet the needs of colorful or full-color displays. [0004] At present, in the organic material layer process...
