DISPLAY DEVICE AND DRIVING DEVICE THEREOF

摘要

The present invention relates to a display device. A data driving unit of the display device includes switch devices supplying data voltage of an input image to data lines during a period of driving the display device, and supplying an alternating current signal having the same phase as that of a touch driving signal to output channels with the output channels of a driving circuit being connected during a period of driving a touch sensor, thereby minimizing parasitic capacitance connected to the touch sensors during a period of driving the touch sensor and reducing a chip size of a data drive IC.
