Brightness compensation method, brightness compensation device and electronic equipment

Abstract

The invention relates to a brightness compensation method and device. The method comprises the steps of receiving an instruction for lighting up a screen; lighting up pixel units in the screen; before lighting up the pixel units in the screen, or in the process of lighting up the pixel units in the screen, or after lighting up the pixel units in the screen, reading brightness compensation data; performing brightness compensation on the lighted-up pixel units according to the brightness compensation data. According to the technical scheme provided by the invention, the pixel units are firstly lighted up; then, the pixel units are subjected to brightness compensation according to the brightness compensation data; a user is enabled to immediately see that the screen is lighted up after the instruction input; further, the brightness compensation can be performed on the pixel unit according to the brightness compensation data after the screen lighting up, the brightness compensation on the screen can be completed in the process that the eyes of people adapt to the lighting-up screen watching, so that the experience of the user in the process of watching the screen from the closing time to the lighting-up time can be integrally improved.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a brightness compensation method, a brightness compensation device and an electronic device. Background technique [0002] As the size and resolution of current display devices increase, the number of pixel units in the screen increases, which leads to an increase in the length of wires connecting pixel units in the same row or column. Since the wire has a certain resistance, when the current signal is transmitted, the longer the wire, the greater the voltage drop. Therefore, when the driver chip transmits the driving signal from one side of the screen to the pixel unit on the other side through the wire, the driver The voltage of the signal will drop significantly, resulting in lower brightness of the pixel units farther away from the driver chip, and then causing the screen to appear uneven in brightness as a whole, that is, there is mura on the screen. In addit...

AI Technical Summary

Problems solved by technology

For the above data, it takes a lot of time to read the screen every time it is turned on, and to generate a compensation signal based on the data, and other data may be loaded during the screen lighting process. It may take more than 1s, which will lead to poor user experience
