Abstract

The invention provides a method, a system and a device for determining ambient light influence of an LED display screen, and electronic equipment. Respectively acquiring a first color measurement parameter, a second color measurement parameter and a third color measurement parameter when the pixel is displayed on the display screen at the first gray scale, the second gray scale and the third gray scale; wherein the first color measurement parameter corresponds to the first gray scale, the second color measurement parameter corresponds to the second gray scale, and the third color measurement parameter corresponds to the third gray scale; according to the first color measurement parameter and the second color measurement parameter of each pixel, determining a color deviation parameter corresponding to the pixel; and according to the third color measurement parameter and the color deviation parameter of each pixel, determining an ambient light influence parameter corresponding to the pixel. According to the scheme, the ambient light influence parameter of each pixel of the LED display screen under the influence of the ambient light can be determined.

Description

technical field [0001] The present application relates to the technical field of calibration, and in particular, to a method, system, device, electronic device, and computer-readable storage medium for determining the influence of ambient light on an LED display screen. Background technique [0002] One pixel of an LED (Light-Emitting Diode, light-emitting diode) display screen encapsulates three light-emitting materials. Due to defects in the material process and the process of generating packaged lamp beads, there will be inconsistent attenuation of the entire screen during the use of the LED display. Therefore, before the LED screen is delivered, pixel-by-pixel correction of the LED display is required. In this process, the image of the turned-on LED display screen can be collected by a CCD (Charge Coupled Device Camera) camera, and then the color description matrix of each pixel of the display screen can be determined according to the image, and each pixel can be correc...
