Abstract: A touch screen scanning method, a device, and a system are provided. Only a display scan or one touch scan is performed in each period of each frame scanning cycle, and then the display scan and/or at least one touch scan is completed in each frame scanning cycle. The display scan and the at least one touch scan do not interfere with each other during each process, thereby ensuring accuracy of a scan result and display performance of a touch screen.
