Abstract

An embodiment of the present invention provides a display control method, a display controller, and a spliced ​​display system, wherein the display control method is applicable to a spliced ​​display screen including a plurality of display units, and the method includes: determining brightness attenuation from the plurality of display units The largest display unit; adjust the white balance parameter of the display unit with the largest brightness attenuation to the preset white balance parameter; determine the first brightness attenuation parameter of the display unit with the largest brightness attenuation after adjustment; adjust the white balance parameters of other display units The parameters are balanced so that the difference between the adjusted second brightness attenuation parameter of the other display unit and the first brightness attenuation parameter is within a preset range. The invention can effectively reduce the display difference among the display units in the spliced ​​display screen and improve the display effect.

Description

Technical field[0001]The present invention relates to the field of display, 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 techniques can be used, and multiple relatively independent display units can be spliced ​​to get large-sized splicing display to apply in scenarios such as large indoor and outdoor display and monitoring.[0003]That is, the splicing display can include a plurality of identical display units. When the hardware and hardware configuration of each block display unit, the display effect of each display unit should be consistent, and its brightness and chrominance can be maintained. During use, over time, the brightness and chromation of the display unit usually attenuate.[0004]However, due to the difference in the individual difference between the display unit, the decay of the brightness and chromaticity of the display unit...
