Abstract: A display device includes a display panel including pixels, a touch panel including electrodes, a proximity sensor which is adjacent to the touch panel and detects proximity with respect to an object based on a capacitance variation, a display driver which drives the display panel and a touch controller which drives the touch panel and the proximity sensor. Here, the touch controller provides a negative voltage to the proximity sensor when the proximity sensor detects that the object approaches the proximity sensor such that a shortest distance from the object to the proximity sensor is equal to or less than a first reference distance.

Abstract: Provided is an inspection device for inspecting a touch-sensing device including a plurality of touch sensors, the inspection device including a data receiver configured to receive raw data from a touch integrated circuit (IC) that is configured to supply a signal for inspection to the touch-sensing device, and that is configured to measure a value output from the touch-sensing device, and a data processor configured to determine operability of the touch-sensing device by using the raw data, and configured to remove noise from the raw data by using first data measured when the touch-sensing device is not electrically connected to the touch IC.
