Patent number: 12272322Abstract: The present disclosure relates to a drive method of a display system, a display system and an electronic device. The drive method includes: sending, by a controller, first drive signals to a display panel in sequence and sending, by the controller, second drive signals to a variable phase retarder in sequence, where first drive signals cause liquid crystals of each of the sub-display regions to deflect one by one, and the second drive signals cause sub-phase retarders to change state one by one; sending, by the controller, third drive signals to the display panel in sequence, where the third drive signals cause sub-backlight regions to turn on in sequence, and each of the sub-backlight regions turns on not earlier than the corresponding sub-phase retarder changes state, where the corresponding sub-phase retarder refers to a sub-phase retarder for accepting light emitted by the sub-display region corresponding to the sub-backlight region.Type: GrantFiled: June 14, 2022Date of Patent: April 8, 2025Assignee: BOE Technology Group Co., Ltd.Inventors: Nan Han, Wenhong Tian, Zijiao Xue, Zhiqiang Wang, Shuaishuai Xu
