Abstract: Disclosed is an apparatus for inspecting a defect of a display panel. The apparatus for inspecting includes the display panel that displays an image, an input sensor that is disposed on the display panel and senses an input applied from outside, a sensor driving part that drives the input sensor, and an inspection part that is connected with the sensor driving part, sets a frequency of the input sensor to an inspection frequency, and detects the defect of the display panel based on a change in a jitter occurring when the input sensor is driven at the inspection frequency. The inspection frequency includes a harmonic frequency of a driving frequency of the display panel.

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: A display device includes a display panel and an input sensing panel. The input sensing panel includes pluralities of first and second sensing electrodes and electrostatic induction patterns, each of which is connected to a sensing electrode from one of the pluralities of sensing electrodes and overlaps another sensing electrode from the other one of the pluralities of sensing electrodes. The input sensing panel includes a first area where deviations of mutual capacitances between the first and second sensing electrodes are small and a second area where the deviations are large. The electrostatic induction patterns include first electrostatic induction patterns disposed in the first area and second electrostatic induction patterns disposed in the second area, the second electrostatic induction patterns having a different area from the first electrostatic induction patterns, or the number of second electrostatic induction patterns being different from the number of first electrostatic induction patterns.

Abstract: Disclosed is a display device including a display panel, an input sensing layer, a display controller that drives the display panel and outputs a synchronization signal including information about an operating frequency of the display panel, and a sensing controller that receives the synchronization signal and determines an operating frequency of the input sensing layer based on the synchronization signal. A driving frame of the display panel includes a first section during which an image is not displayed and a second section during which an image is displayed. During the driving frame, the display controller transmits a data signal for displaying an image to the display panel. The synchronization signal includes a first pulse corresponding to a timing of the first section, and a second pulse corresponding to a timing of the second section.
