  • Publication number: 20240021125
    Abstract: Provided are a light sensing uniformity compensation method, a method for generating a light sensing uniformity compensation table, and a display device. According to each light sensing acquired value, a position of a light sensing module corresponding to each light sensing acquired value, and a relationship between the reference compensation values and the positions of the light sensing modules, a light sensing compensation value corresponding to each to-be-compensated light sense acquired value is determined, to correspondingly compensate for the to-be-compensated light sense acquired value. The plurality of compensated light sensing acquired values are output.

  • Patent number: 11798455
    Abstract: A display device, a display control method, and an electronic equipment are provided. The display device includes a display panel, a driving module, a time schedule controller, a collection circuit, and a control module. The control module obtains initial collection data provided by sensing units, determines crosstalk extent on the initial collection data, and synchronously compensates the initial collection data according to the crosstalk extent. Induced charges corresponding to target collection data are reduced, or interference to data signals is prevented.

  • Patent number: 11341876
    Abstract: A white balance adjusting system for a display device includes a control member including a register storing white balance control commands and a preset white balance lookup table. A built-in self-test module is coupled to the control member and configured to store a test pattern. A first storage element is disposed in the display device. An optical sensor is configured to measure brightness and chroma data of the screen according to the test pattern. An external control device is operated by the control member to execute the white balance control commands so that white balance adjustment is implemented according to the preset white balance lookup table and the brightness and the chroma data of the screen, and a corrected white balance lookup table is produced. The corrected white balance lookup table is stored in the first storage element and provided to update the preset white balance lookup table.

  • Patent number: 11257449
    Abstract: The present invention provides a display device driving method and a display device. The method directly loads compression de-mura data in a compressed state into a memory during booting, which enhances a booting speed. Decoding only performed for current display position when images are displayed, which lowers occupation of the memory. Furthermore, multi-thread parallel decoding of the de-mura data is achieved by identifiers and decoding modules, which drastically increases a decoding speed.
