Abstract
Disclosed is a touch display device that detects multiple touches in a touch sensing scheme of sensing change in capacitance of a surface of a touch electrode. The touch display device includes a display panel including a touch electrode; a switch circuit connected to each of measurement positions of the touch electrode; and a touch driving circuit connected to each of the measurement positions of the touch electrode via the switch circuit, wherein the touch driving circuit is configured to apply a touch driving signal to the touch electrode, receive sensed values from the measurement positions based on an operation of the switch circuit, and calculate coordinates of multi-touch points on the touch electrode, based on the sensed values.
