Abstract
The present application relates to the field of display technologies, and provides a display panel including a base substrate; a plurality of pixel structures arranged in an array on the base substrate including a main light-emitting portion and an auxiliary light-emitting portion independently driven and having a same light-emitting color, as well as a microstructure covering the main light-emitting portion and the auxiliary light-emitting portion, light emitted by the main light-emitting portion and the auxiliary light-emitting portion of the same organic light-emitting sub-pixel is emitted through the microstructure; and wherein the initial brightness of the organic light-emitting sub-pixel is the initial brightness of the main light-emitting portion; and a control structure configured to control brightness of the auxiliary light-emitting portion according to brightness of the main light-emitting portion to compensate the brightness of the main light-emitting portion, so that brightness of the organic light-emitting sub-pixel remains consistent with its initial brightness.
