no. 1 example

[0053] see figure 1 , the first embodiment of the present invention discloses a display unit calibration method. For example, the display unit calibration method can be applied to low-gray uniformity correction, or the display unit calibration method can be applied to uniformity calibration when the brightness of the display unit is lower than the first threshold or lower than the first gray scale. Such as figure 1 As shown, the display unit calibration method includes, for example:

[0054] S11: Acquire first display data when the first display unit applies the first correction coefficient to display;

[0055] Optionally, the display unit herein may be a light panel, a box, a module or other units that can be used for display.

[0056] For example, the display unit may be a light panel, a box, or a unit spliced ​​by at least one light panel or a unit spliced ​​by at least one box.

[0057] S13: Obtain second display data when the first display unit applies the second corr...

Abstract

The embodiment of the invention discloses a display unit correction method and device and a computer readable storage medium. The display unit correction method comprises the following steps: acquiring first display data when a first display unit performs display by applying a first correction coefficient; acquiring second display data when the first display unit uses a second correction coefficient to display; determining a change relationship between the correction coefficient and the display data, the change relationship being used for obtaining a target correction coefficient of the first display unit, or the change relationship being used for obtaining a target correction coefficient of a display unit of the same type as the first display unit; wherein the change relation is obtained based on the variable quantity between the first correction coefficient and the second correction coefficient, the first display data and the second display data, or the change relation is obtained based on the first correction coefficient, the second correction coefficient, the first display data and the second display data. According to the display unit correction method disclosed by the embodiment of the invention, the low-gray correction efficiency of the display unit can be improved.

Description

technical field [0001] The present invention relates to the field of display screen correction, in particular to a display unit correction method, a display unit correction device and a computer-readable storage medium. Background technique [0002] With the development of LED display, customers have put forward higher requirements for the display effect of the display, such as: low power consumption, low graying brightness (the brightness when the display starts to light up), low refresh rate (the display shows low Brightness refresh rate) high demand. At present, manufacturers of display driver chips are trying to meet customers' needs for the display effect of the display. They have developed a method for controlling the brightness of the display lamps by the display driver chip, so that the display has lower graying brightness and lower power consumption. , low brightness and high refresh rate, etc., but this type of display driver chip needs to solve the unevenness of ...
