Abstract
An optical touch control system is disclosed, includes a display panel, first and second optical sensors, first and second light-emitting devices, and a controller. The first and second optical sensors are respectively disposed at opposite corners of the display panel. The first and second light-emitting devices are disposed on the first and second optical sensors, respectively. The controller turns off the first and second light-emitting devices and turns on the first optical sensor to obtain a first frame, only turns on the second light-emitting device and the first optical sensor to obtain a second frame, turns off the first and second light-emitting devices and turns on the second optical sensor to obtain a third frame, only turns on the first light-emitting device and the second optical sensor to obtain a fourth frame, and determines a gesture according to the first through the fourth frames.
