Problems solved by technology

In the existing methods for compensating organic light-emitting diodes in pixel driving circuits, although the compensation for organic light-emitting diodes is realized, the brightness of organic light-emitting diodes usually cannot be guaranteed to remain unchanged, so that the display effect of organic light-emitting display panels after compensation remains the same. not ideal

Abstract

The application discloses an organic light-emitting display panel, an organic light-emitting display device and a pixel compensation method; according to a specific embodiment, the organic light-emitting display panel comprises a plurality of data wire sets; a pixel array; a plurality of pixel drive circuits; a pixel compensation circuit for providing bias current, collecting anode voltage of organic light-emitting diodes and generating compensated data voltage based on the bias current and the anode voltage; a power module for providing bias current to the data wire set and transmitting the bias current to the organic light-emitting diodes through the data wire set; a sampling module for collecting anode voltage of the organic light-emitting diodes through the data wire set; a data voltage generating module for transmitting the compensated data voltage to the pixel drive circuit through the data wire set based on the anode voltage and bias current. The embodiment ensures that the brightness of organic light-emitting diodes is unchanged while compensating the organic light-emitting diodes, so that the organic light-emitting diodes can be compensated more precisely.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to an organic light emitting display panel, an organic light emitting display device and a pixel compensation method. Background technique [0002] Organic Light-Emitting Diode (OLED) is a thin-film light-emitting device made of organic semiconductor materials and driven by DC voltage. It is made of very thin organic material coating and glass substrate, without backlight. These organic materials emit light when an electric current is passed through them. [0003] Generally, the brightness of each pixel varies due to various reasons, such as the difference in the electrical characteristics of each driving transistor, the difference in the high-potential driving voltage depending on the display position, and the difference in the deterioration of the OLED, so that the brightness of the OLED display is different. uneven. When this difference becomes severe, image stic...
