Abstract:
Embodiments of the present disclosure discloses a touch generator, an optical touch system, and a touch method. A force condition of a forced member is detected by a pressure detecting unit. When the forced member touches a display panel, the pressure detecting unit detects the force condition of the forced member and sends a control signal, a light-emitting unit receives the control signal and generates light, and the light emits to the display panel from the forced member, which can prevent false touch, simplify operation, and decrease a difficulty of using the touch generator.
