Abstract: A circuit board includes a base substrate, and a connection structure disposed on the base substrate, and connected to the base substrate by an accessing part. The connection structure includes a first connection electrode, a second connection electrode disposed in a same layer as the first connection electrode, a third connection electrode connected to the first connection electrode on the first connection electrode, and a fourth connection electrode connected to the second connection electrode on the second connection electrode, and disposed in a same layer as the third connection electrode.

Abstract: A display device includes a display panel that displays an image, an input sensing layer disposed on the display panel and that senses an input applied thereto from outside of the display device, a display driver that receives an image signal and drives the display panel at a first driving frequency or a second driving frequency lower than the first driving frequency, and a sensing driver that drives the input sensing layer. The display panel displays the image in a plurality of frames, each including a first period and/or a second period. The sensing driver drives the input sensing layer in the first period of each of the frames when the display panel is driven at the first driving frequency, and drives the input sensing layer in the second period of each of the frames when the display panel is driven at the second driving frequency.

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.
