Patent number: 11775117Abstract: A method of operating a display includes performing a non-synchronized touch scan pattern on a display with a controller coupled to the display. The non-synchronized touch scan pattern schedules touch scans independent of a refresh rate of the display. Upon the controller detecting a first synchronization pulse from a display controller coupled to the controller and the display, a first pulse-checking timer is started. Upon detecting a second synchronization pulse from the display controller and before the first pulse-checking timer expires, a first display refresh rate for the display is obtained from an interval between the first synchronization pulse and the second synchronization pulse. A synchronized touch scan pattern is performed with the controller, and is scheduled to avoid touch scans coinciding with refreshes of the display performed at the first display refresh rate.Type: GrantFiled: July 7, 2022Date of Patent: October 3, 2023Assignees: STMicroelectronics (Beijing) R&D Co., Ltd., STMicroelectronics Ltd.Inventors: Pengcheng Wen, Yuan Yun Wang
