  • Publication number: 20220351692
    Abstract: A method for dimming is adapted for a display device. The method for dimming includes the steps of: obtaining a plurality of first area peak luminance of a plurality of areas of a panel and a backlight plate of the display device; averaging the plurality of first area peak luminance to obtain an overall peak luminance value; looking the overall peak luminance value up in a lookup table to obtain a luminance adjustment value; and adjusting the plurality of first area peak luminance of the plurality of areas into a plurality of second area peak luminance. The plurality of first area peak luminance are a same with or are different from the plurality of second area peak luminance.

  • Publication number: 20210343251
    Abstract: A display system includes a memory, a timing controller, a backlight module, a backlight controller, and a display array. The memory is configured to store a first look-up table and a second look-up table. The timing controller is configured to determine a target illumination value according to a target duty cycle of a backlight control signal and the first look-up table, and determine an original duty cycle according to the target illumination value and the second look-up table, and output the backlight control signal according to the original duty cycle. The backlight controller is configured to control the backlight module according to the backlight control signal. The display array is configured to cooperate with the backlight module to display an image.
