Abstract
A display device includes an in-cell touch display panel, a flexible printed circuit board, and a source driver. The in-cell touch display panel includes touch sensing electrodes, touch sensing pins, pixel electrodes, and source pins. The touch sensing pins are electrically connected to the touch sensing electrodes. The source pins are electrically connected to the pixel electrodes. The flexible circuit board includes dummy pads, touch sensing leads, input pads, output pads, and output signal leads. The touch sensing leads are electrically connected to the dummy pads and the touch sensing pins. The output signal leads are electrically connected to the output pads and the source pins. The source driver includes input terminals and output terminals. The input terminals are electrically connected to the input pads. The output terminals are electrically connected to the output pads. The source driver does not include a touch sensing terminal.
