Abstract
A display device and a display method of the display device are provided. A sub-image generation module generates a plurality of sub-image signals based on a received image signal. A dithering module adjusts a grayscale value of a target adjustment pixel in the sub-image signals based on a blue noise mask and a gray level lookup table. A control unit controls an image displayed by an image unit based on the grayscale value of the target adjustment pixel.
Claims15
A display device, comprising:
- a sub-image generation module, configured to generate a plurality of sub-image signals based on a received image signal;
- a dithering module, coupled to the sub-image generation module, and the dithering module comprising a blue noise mask and a gray level lookup table, wherein the dithering module is configured to adjust a grayscale value of a target adjustment pixel in the sub-image signals based on the blue noise mask and the gray level lookup table;
- and
- a control unit, coupled to the dithering module and an image unit, and the control unit being configured to control an image displayed by the image unit based on the grayscale value of the target adjustment pixel.
