Abstract

The invention discloses a point-by-point correction method for an LED display screen, and belongs to the field of LED display screen correction, and the method comprises the steps: S100, obtaining thebrightness value of each LED single lamp on an LED display screen; S200, calculating to obtain a standard brightness value of each LED single lamp based on a gradient descent method according to thebrightness values of all the LED single lamps; S300, calculating a correction coefficient of each LED single lamp according to the brightness value of each LED single lamp and the standard brightnessvalue; and S400, correcting the LED display screen according to the correction coefficient of each LED single lamp. According to the invention, the brightness difference between the LED single lamps can be well eliminated, the uniformity of the LED display screen is remarkably improved, and the display quality is improved.

Description

Technical field

[0001] The invention relates to the field of LED display screen calibration, in particular to a point-by-point calibration method for LED display screens.Background technique

[0002] The LED display is a display device composed of small LED modules to display various information such as text, images, video, and video signals. Such asfigure 1 As shown, the LED display screen 100 is generally composed of an LED box 200, an LED module 300, and an LED light (or single lamp) 400. The LED module 300 is composed of LED single lamps 400; the LED cabinet 200 can be composed of LED modules 300 or directly composed of LED single lamps 400; the LED display 100 can be composed of LED cabinet 200 or LED module 300 or LED single The lamp 400 is composed.

[0003] The reason why the LED display screen has been widely valued and developed rapidly is inseparable from its own advantages. These advantages can be summed up as: high brightness, low working voltage, low power consumption, large siz...
