    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.

    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: An electronic apparatus includes an electronic panel including a plurality of sensing groups spaced apart from each other, and an electronic module overlapping with the electronic panel in a plan view. Each of the sensing groups includes a first sensing electrode extending in a second direction, and second sensing electrodes spaced apart from each other in the second direction, located on the same layer as the first sensing electrode, and face the first sensing electrode in a first direction. An opening overlapping with the electronic module and penetrating a first sensing group of the sensing groups is defined in the electronic panel, and at least one selected from the first sensing electrode and the second sensing electrodes of the first sensing group extends along an edge of the opening.

    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.
