Problems solved by technology

[0003] In the prior art, when measuring the value of a display screen, it is necessary to keep the measuring instrument at a certain distance from the display screen, and the measuring lens must be kept parallel to the plane of the display screen, and the position of the display screen must be adjusted so that The imaging of the display screen in the lens is a standard or approximate rectangle, so that the measurement values ​​of the relevant points of the display screen can be read well, but in the mass production measurement, it is necessary to customize the corresponding fixtures to align the display screen and the measurement equipment. For positioning, but because the size of the display screen is various, each size needs a corresponding manufacturing tool, which is quite time-consuming and laborious for production, and the cost is high, so how to quickly locate the corresponding point of the display screen Coordinates without being affected by placement have become a key problem in solving production and measurement

Abstract

The invention discloses a display screen plane luminance measurement method, device, computer equipment and storage medium, wherein the method includes: obtaining the two-dimensional coordinate data stream lattice of the display screen, and then extracting and displaying from the two-dimensional coordinate data stream lattice The four vertex coordinates of the screen, and then calculate the point coordinates of other points in the display screen according to the four vertex coordinates, and finally select some point coordinates or all point coordinates in the display screen for gray scale measurement. The invention solves the requirement that the position of the display screen should be fixed and that the display screen should be placed parallel to the lens of the measuring instrument in the measurement, and also avoids the problem that a corresponding manufacturing tool is required for each size of the display screen, reducing the Human, material and financial resources improve the efficiency and accuracy of measurement.

Description

technical field [0001] The invention relates to display screen plane brightness measurement, more specifically a display screen plane brightness measurement method, device, computer equipment and storage medium. Background technique [0002] With the development of the display field, people have higher and higher requirements for the brightness of the display screen, but because most of the backlight of the display screen is passive, and it is a surface light source composed of point light sources, due to the inconsistency of the LED lights, even The same batch of LED lamps cannot have a complete voltage and brightness output relationship, which makes the brightness tested in different places on the display surface of the display screen may be very different, and the increasing quality requirements, for the display screen The brightness requirement has shifted from the center of the display to the surface of the display. Only by ensuring the uniform brightness of the entire ...
