Title: OPTICAL TOUCH CONTROL APPARATUS AND MANUFACTURING METHOD THEREFOR, DISPLAY AND ELECTRONIC DEVICE
Abstract:
Disclosed are an optical touch control apparatus and a manufacturing method thereof, a display and an electronic device. The optical touch control apparatus comprises: a pixel array (11), wherein the pixel array (11) comprises a plurality of pixel sub-circuits (101), wherein each of the pixel sub-circuits (101) comprises M first pixels (1011) and N second pixels (1012), a detection light ray with a pre-set frequency is transmitted by means of the second pixels (1012), and M and N are both positive integers; a light-receiving array (12), wherein the light-receiving array (12) comprises a plurality of light receivers (121), and wherein the plurality of light receivers (121) correspond to the plurality of pixel sub-circuits (101), and each of the light receivers (121) generates an inductive signal by receiving a reflective light ray of the detection light ray transmitted by corresponding second pixels (1012); and a detection circuit (13), wherein the detection circuit (13) is connected to the plurality of light receivers (121), and the detection circuit (13) performs the touch control positioning according to the inductive signal generated by each of the light receivers (121), so that the integration of display and optical touch control can be realized and a higher integration degree thereof is obtained.
