METHOD OF DRIVING LIGHT SOURCE MODULE AND DISPLAY DEVICE USING THE METHOD

摘要

A display device includes: a light source module which includes a plurality of light-emitting blocks; a display panel which includes a plurality of pixels and is divided into a plurality of image blocks corresponding to the light-emitting blocks; a light source module control unit which divides an image signal into the image blocks, generates a color dimming signal corresponding to a first image block among the image blocks, obtains pixel distortion values and pixel improvement values corresponding to each pixel of the first image block by analyzing the first image block, determines whether to perform color dimming or not on a driving signal of a first light-emitting block corresponding to the first image block based on the pixel distortion values and the pixel improvement values, and drives the first light-emitting block based on the determination result.

1. A method of driving a light source module, which provides light to a display panel having a plurality of pixels and comprises a plurality of light-emitting blocks, on a light-emitting block-by-light-emitting block-basis, the method comprising:
dividing an image signal into a plurality of image blocks corresponding to the light-emitting blocks by analyzing the image signal; generating a color dimming signal which corresponds to a first image block among the image blocks; obtaining a pixel distortion value and a pixel improvement value corresponding to each pixel by analyzing the first image block; determining whether to perform color dimming on a first light-emitting block, which corresponds to the first image block, based on the pixel distortion value and the pixel improvement value; and driving the first light-emitting block based on the determination result.
