Abstract:
Related to is the field of light-emitting panel manufacture, and a light-emitting panel and a method for manufacturing the same are provided, which aim to improve uniformity of light emission of an Organic Light-Emitting Diode (OLED) manufactured by Inkjet Printing (IJP). The light-emitting panel sequentially comprises an ITO substrate, a light-emitting layer, a light-shielding layer, and a cover glass. The method comprises forming a multilayer structure sequentially including an ITO substrate, a light-emitting layer, a light-shielding layer, and a cover glass. According to a size of an edge warp of a light-emitting area of the OLED, a light-shielding layer is designed at a corresponding position of the light-emitting area on the cover glass, and a position of a non-uniform edge is subjected to light-shielding processing, so that the problem of non-uniform light emission caused by the edge warp of the organic light-emitting layer is solved. A display part can thus be uniformly showed, thereby effectively improving the uniformity of light emission of the OLED manufactured by IJP.
