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

Embodiment Construction

[0048] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the implementation manners of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.

[0049] figure 1 It is a flow chart of a white point coordinate compensation method provided by an embodiment of the present disclosure. see figure 1 , the method includes:

[0050] Step 101: Obtain the target luminance and target white point coordinates of the display module in the black insertion mode, and the display module includes a backlight source.

[0051] In a display module, a backlight and a display panel are assembled together to form a display module.

[0052]The color coordinate is the coordinate of the color, and the commonly used color coordinate is x on the horizontal axis and y on the vertical axis. The whitest point of the display, that is, the point when the display shows 255, 255, and 255 white is called the...

Abstract

The disclosure provides a white point coordinate compensation method, device, computer equipment and storage medium, belonging to the field of display technology. The method includes: obtaining the target brightness and the target white point coordinates of the display module in the black insertion mode, the display module including a backlight; To achieve the white point coordinates corresponding to the target brightness; use the difference between the white point coordinates in the constant light mode and the white point coordinates in the black insertion mode to compensate the target white point coordinates.

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...
