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.

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: An application method of demura data having a uniform format includes: in step S12, it is determined whether demura data having a first format is stored in a first memory; if yes, step S13 is performed; if no, step S16 is performed; in step S13, it is checked whether the demura data having the first format is consistent with demura data having a second format and stored in a second memory; if yes, step S14 is performed; if no, step S16 is performed; in step S14, the demura data having the first format in the first memory is read; in step S15, a demura data compensation is activated; and in step S16, demura data having the first format is generated, according to the demura data having the second format and stored in the second memory, and stored; step S15 is performed.

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.
