Title:
DISPLAY DEVICE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/163441
Kind Code:
A1
Abstract:
A display device is disclosed. The display device comprises: a display including a plurality of pixels; a memory for storing a first cross-talk weight based on pixels included in a pixel line to which a target pixel belongs, and a second cross-talk weight based on pixels included in another pixel line scanned simultaneously with the pixel line to which the target pixel belongs; and a processor for simultaneously applying image signals to the plurality of pixel lines spaced apart by regular intervals. The processor can: acquire a grayscale value of each of the pixels included in the plurality of pixel lines from among the plurality of pixels; acquire, on the basis of the acquired grayscale value, first histogram information indicating, by grayscale period, the number of pixels included in another pixel line that is simultaneously scanned with the pixel line to which the target pixel belongs and second histogram information indicating, by grayscale period, the number of pixels included in the pixel line to which the target pixel belongs; identify a first cross-talk amount on the basis of the first histogram information and the first cross-talk weight; identify a second cross-talk amount on the basis of the second histogram information and the second cross-talk weight; acquire grayscale correction data of the target pixel on the basis of the first cross-talk amount and the second cross-talk amount; and acquire a corrected grayscale value of the target pixel on the basis of the acquired grayscale correction data.
