Abstract

A method for adjusting chromatic aberration of a display device comprises the following steps: defining a chromatic aberration tolerance range; determining the color difference change range of the display device according to the color differences of the plurality of display screens; defining a plurality of color difference adjustment grades according to the color difference tolerance range and the color difference change range; setting a color compensation value corresponding to each color difference adjustment level; and selecting a corresponding color difference adjustment level for each display screen based on one of the plurality of display screens, and inputting a color compensation value corresponding to the selected color difference adjustment level.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a method for adjusting the color difference of the display device. Background technique [0002] figure 1 It is a schematic diagram of an existing display device. Such as figure 1 As shown, the display device 1 includes a plurality of spliced ​​display screens 10 . For the existing display device 1, there is a color difference between the display screens 10, which makes the displayed images uncoordinated. In order to coordinate the display screens, it is necessary to manually adjust the set values ​​of the three primary colors of red, blue and green of each display screen 10 , that is, the color difference of each display screen 10 is reduced through white balance adjustment. The above method is not only time-consuming, but also requires professionals to complete. At the same time, if one of the display screens 10 needs to be replaced due to aging, the ...
