ON-SCREEN-DISPLAY MODULE, DISPLAY DEVICE, AND ELECTRONIC DEVICE USING THE SAME

摘要

An on-screen-display module includes an optical signal processing unit and a control unit. The optical signal processing unit receives an optical signal sensed by an image sensor and outputs a touch signal. The control unit is electrically connected to the optical signal processing unit, and adjusts a display panel to execute a corresponding display effect according to the touch signal. By applying the on-screen-display module to a display device or an electronic device, the display effect of the display panel can be directly modulated through the control unit when the host is not powered on, and advantages of further saving system energy and being convenient for a user are achieved.
