Abstract

The invention discloses a pixel compensation device, a driving method thereof and display equipment, relates to the technical field of display, and is used for simplifying the pixel compensation device and reducing the power consumption of a chip end power supply. The pixel compensation device comprises a switching circuit, a storage circuit, a first reset circuit, a driving transistor, a reference circuit and a data input circuit, wherein the reference circuit and the data input circuit are electrically connected with the storage circuit. And the switching circuit and the storage circuit are electrically connected with a power supply end. A control electrode of the driving transistor is electrically connected with the storage circuit, a first electrode of the driving transistor is electrically connected with the switching circuit, and a second electrode of the driving transistor is electrically connected with the light-emitting circuit. The first reset circuit, the reference circuit and the data input circuit are all controlled by the same control signal. The pixel compensation driving method provided by the invention is applied to the pixel compensation device. The display equipment provided by the invention comprises the pixel compensation device.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a pixel compensation device, a driving method thereof, and a display device. Background technique [0002] In recent years, low-power high-resolution displays and displays with adjustable refresh rates have attracted more and more attention. The traditional low temperature polysilicon (English full name: Low Temperature Poly-Silicon, English abbreviation: LTPS) thin film transistor display technology has the advantage of high mobility and can be applied to high refresh rate and high resolution displays; amorphous indium gallium zinc oxide ( a-IGZO) thin film transistor display technology has extremely low leakage current, which is conducive to low power consumption and low refresh rate display. Therefore, the combination of the two in the same pixel circuit is of great significance to promote the development of high-performance displays. As a result, LTPO (full nam...
