Abstract

The invention discloses a display panel and a display device. The display panel includes a first base and a second base that are oppositely arranged, and a side of the first base close to the second base is provided with a plurality of sub-pixel units, and a side of the second base close to the first base A plurality of photodetection units are arranged on one side, and the photodetection units are arranged correspondingly to the sub-pixel units; The signal is converted into an electrical signal. The display panel and the display device provided by the present invention can detect the light intensity change of the sub-pixel in real time, and compensate the sub-pixel in real time, so as to achieve the purpose of improving the display state of the display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] In the manufacture of organic light-emitting diode (OLED) display devices, especially oxide organic light-emitting diode (OxideOLED) display devices, in addition to designing the compensation circuit inside the pixel, it is usually necessary to use charge-coupled The device (CCD) performs a precise optical calibration at the pixel (pixel) level, performs external electrical compensation of the pixel circuit, and compensates for the offset of the threshold voltage (Vth). However, this compensation method cannot detect the light intensity change of each sub-pixel in real time, so that the OLED display device cannot reach an optimal display state. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems in the above-mentioned prior art, and provides a ...
