Abstract: A pixel driving circuit, a driving method thereof, and a display panel are disclosed. A second transistor stores a threshold voltage of a first transistor in a first capacitor according to a second scan signal, so as to compensate an influence of the threshold voltage on a driving current. A fifth transistor makes a voltage difference between a first node and a second node irrelevant to a second voltage signal according to a fourth scan signal, so as to improve a current attenuation issue caused by a voltage drop during a signal transmission.

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.
