Abstract

The invention relates to a display screen brightness and chrominance correction method and device based on a mobile terminal. The correction method comprises the following steps: controlling a to-be-corrected area of a display screen connected with the mobile terminal to display a preset picture through the mobile terminal; collecting a first correction image when the preset picture is displayed in the to-be-corrected area through the mobile terminal; acquiring reference brightness and chrominance data; obtaining a brightness and chrominance correction coefficient of the to-be-corrected area according to the first correction image and the reference brightness and chrominance data; and sending the brightness and chrominance correction coefficient to the display screen to correct the area to be corrected. According to the invention, the brightness and chrominance difference of the display screen is eliminated based on the adjustment of the mobile terminal, so that the brightness and chrominance of the display screen are highly consistent, and the correction efficiency and the correction effect are improved.

Description

technical field

[0001] The invention relates to the technical field of LED display correction, in particular to a mobile terminal-based display screen brightness and chromaticity correction method and a mobile terminal-based display screen brightness and chromaticity correction device. Background technique

[0002] Displays such as LED displays have been widely used in city squares, commercial centers and other places due to their bright colors, high visibility, low power consumption, environmental protection and energy saving. There is a problem of inconsistency in human vision. The root cause of this inconsistency in brightness and chromaticity is the LED itself. For example, LED lamps in the same production batch may have a 50% change in brightness and a 15-20nm change in wavelength (chromaticity). These differences are very important to the human eye. Visually it is very noticeable. Therefore, the problem of LED displays of the same grade in different batches is more p...
