White point coordinate compensation method and device, computer equipment and storage medium

Abstract

The invention provides a white point coordinate compensation method and device, computer equipment and a storage medium, and belongs to the technical field of display. The method comprises the following steps: acquiring target brightness and target white point coordinates of a display module in a black frame insertion mode, wherein the display module comprises a backlight source; respectively determining white point coordinates corresponding to the target brightness to be reached by the backlight source in a black insertion mode and a normally-on mode; and compensating the target white point coordinate by adopting a difference value between the white point coordinate in the normally-on mode and the white point coordinate in the black frame insertion mode.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a white point coordinate compensation method, device, computer equipment and storage medium. Background technique [0002] When the user wears a virtual reality (VR) device with a liquid crystal display and shakes his head, there will be a persistent phenomenon in the picture he sees. , there will be smearing, causing users to feel dizzy. [0003] In the related art, the above-mentioned problem can be solved by adopting a backlight black insertion technology. In the backlight black insertion technology, a screen display cycle of a VR device corresponding to a screen is divided into three parts: data scanning time (ST), liquid crystal response time (RT) and backlight turn-on time (BLUT), and the backlight only needs to be When the BLUT is turned on, a normal picture will be produced at this time, and it will remain closed at other times, and a black picture will ap...

AI Technical Summary

Problems solved by technology

At present, the burning device cannot support the calculation of the white point coordinates of the backlight in the black plug-in mode, but only supports the calculation of the white point coordinates of the backlight in the constant light mode, and directly burns the white point coordinates calculated in the constant light mode to the In the IC of the VR device in the black plug-in mode, the IC of the VR device uses the coordinates of the white point to control the backlight source, which will inevitably cause the coordinates of the white point to not match the display screen, resulting in color deviation of the display screen
