Abstract

The invention provides a display control method, a display controller and a splicing display system. The display control method is suitable for a splicing display screen comprising a plurality of display units, and comprises the following steps of: determining the display unit with the highest luminance attenuation from the plurality of display units; adjusting the white balance parameter of the display unit with the highest luminance attenuation to a preset white balance parameter; determining a first luminance attenuation parameter of the display unit with the highest luminance attenuation; and adjusting the white luminance parameters of the other display units, and allowing the difference between second luminance attenuation parameters of the other display units adjusted and the first luminance attenuation parameter to be within a preset range. The display difference between the display units in the splicing display screen can be effectively reduced and the display effect is improved by the display control method, the display controller and the splicing display system provided by the invention.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display control method, a display controller and a splicing display system. Background technique [0002] With the rapid development of science and technology, screen splicing technology can be used to splice multiple relatively independent display units to obtain a large-scale spliced ​​display screen, which can be used in large-scale indoor and outdoor display and monitoring scenarios. [0003] That is to say, the spliced ​​display screen may include: a plurality of identical display units. When the hardware and software configuration of each display unit is the same, the display effect of each display unit should be the same, and its brightness and chromaticity can be kept consistent. During use, the brightness and chromaticity of a display unit usually decay over time. [0004] However, due to the individual differences among the display units, it is difficult fo...
