Abstract
A display device with a signal controller is disclosed. The display device includes a display panel, a scan driver, a data driver, a touch screen including a touch controller, a graphics controller and a signal controller. The signal controller generates a multiple control signal for controlling the timing of recording of an image signal and the timing of driving of the touch screen panel. The signal controller transmits the multiple control signal to the graphics controller and the touch controller.

15. A driving method of a display device including a touch screen panel, the method comprising:
-
generating a multiple control signal in a waveform switched between a high level voltage and a low level voltage in a frame during which a data signal is applied to a plurality of pixels, the multiple control signal for controlling timing of recording of an image signal and timing of driving of the touch screen panel; generating the multiple control signal at the high level voltage in a porch period between a plurality of frames; performing a first recording of the image signal when the porch period starts; and driving the touch screen panel for a duration after a second recording of the image signal when the multiple control signal switches to the high level voltage in the frame. - View Dependent Claims (16, 17, 18, 19, 20)
