Abstract

The invention discloses a display panel and a compensation method of the display panel, wherein the display panel comprises at least one pixel compensation circuit and a plurality of pixel driving circuits; the pixel compensation circuit comprises a voltage adjusting module, a conversion module, a first storage module and a comparison module; each pixel driving circuit comprises a data writing module, a driving module, a second storage module, a sensing module and a light emitting element; and the pixel compensation circuit is used for compensating the threshold drift of the driving modules. According to the invention, the threshold drift of the driving modules in the display panel is compensated, and the problem of uneven displaying caused by the threshold drift of an organic light emitting display is solved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a compensation method for the display panel. Background technique [0002] Organic Light Emitting Diode (OLED) display devices are considered to be the next generation of display devices due to their characteristics of fast response, thinness, and power saving. [0003] A pixel constituting an OLED display device generally includes an OLED and a pixel driving circuit. The pixel drive circuit includes a drive module for driving the OLED. The drive module usually uses a drive transistor. By applying different electrical signals to the gate of the drive transistor to control the drive current output by the drive transistor to the OLED, the OLED responds to the drive current. glow. [0004] However, due to process, aging and other reasons, the threshold Vth of the driving transistor will drift and the mobility will attenuate. The char...
