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.

Abstract: A timing controller is provided. A data enable signal in a timing control module is regenerated by a signal regenerating module. A number of vertical valid display rows is regenerated as a vertical valid display period. A total charge time of all rows of pixels in each frame can be increased effectively. A horizontal blanking period is changed sequentially in a row-by-row manner, thereby compensating charge effects of rows of pixels accurately.

Abstract: The present application provides a backlight module and a display device. The present application converts a display image into control information through a driver board, and can precisely control a mini-LED backlight. The driver board is provided with multiple interfaces for transmitting control signals based on different transmission protocols, so the compatibility of the entire display device is improved. In addition, the driver board can be continuously updated by using programmable devices to meet the needs of users.
