Abstract: A driving method is applied to a driving switch having a first terminal, a second terminal coupled to a first light emitting diode (LED), and a control terminal. First, supply a reset voltage to the control terminal. When the second terminal electrically connects with the control terminal and the first terminal receives a precompensation voltage, the difference between the voltage at the control terminal and the preset voltage is equal to the threshold voltage of the driving switch. When the second terminal electrically connects with the control terminal and the first terminal receives a data voltage, the difference between the voltage at the control terminal and the data voltage is equal to the threshold voltage of the driving switch. When the first terminal receives a power voltage, a driving current is generated according to the voltage at the control terminal and the power voltage to drive the LED.

Abstract: A touch display device includes a controller, a source driver, several multiplexers, and several touch sensors. The source driver is configured to output several data signals. The multiplexers are coupled to the controller and the source driver, and are configured to transmit the plurality of data signals to an active area according to at least one enable period of a multiplexing signal. The touch sensors are coupled to the controller, and are configured to receive a touch signal outputted from the controller. The touch signal includes a touch pulse. A touch pulse starting-time interval and a touch pulse ending-time interval of the touch pulse are located in at least one disable period of the multiplexing signal, and the touch pulse and the at least one enable period partially overlap in time sequence.

Abstract: A method for driving a display device is provided. The display device includes a first driving circuit and a pixel array. The driving method includes the following step. In a first mode, by using the first driving circuit, a first light emission start signal is received to drive the pixel array. The first light emission start signal includes a plurality of first pulses, and duration of each of the first pulses is respectively overlapped with at least a part of a period of each of a first frame and at least one second frame. In a second mode, by using the first driving circuit, a second light emission start signal is received to drive the pixel array. The second light emission start signal includes a second pulse. Duration of the second pulse is overlapped with at least a part of a period of the first frame, and the second light emission start signal remains at a first level in a period of the at least one second frame.
