Abstract
An organic light-emitting diode display panel includes a substrate on which an OLED (organic light-emitting diode) light-emitting element is mounted. The OLED light-emitting element includes an OLED organic layer. A black silicon structure is disposed on the substrate and reveals the OLED organic layer. The black silicon structure absorbs ambient light to reduce the reflectance of the ambient light. By disposing the black silicon structure around the OLED organic layer or by directly forming the OLED organic layer in the black silicon structure, the extremely high light absorbing capability of the black silicon structure is used to significantly reduce the reflectance of the ambient light. A clear display effect in a bright environment can be achieved under smaller luminance, reducing the luminance of the display panel and saving the power consumption. Furthermore, the number of films and the overall thickness of the panel can be reduced.
