Abstract: A display apparatus includes an integral integrated circuit and a display panel. The integral integrated circuit includes a gate channel which outputs a gate primitive signal and a data channel which outputs a data voltage. The display panel includes a level shifter which amplifies the gate primitive signal to generate a gate signal. The display panel is configured to display an image based on the gate signal and the data voltage. The display panel includes a first gate line extending in a first direction and a second gate line extending in a second direction. The second direction is different from the first direction. The second gate line is connected to the first gate line. The level shifter is connected to the second gate line.

Abstract: The present disclosure relates to a display device. The display device includes a display module and a sensing circuit board including a plurality of sensing dots disposed on the display module and generating a magnetic field. Each of the sensing dots includes continuous first and second periods. Additionally or alternatively, the sensing dots includes a transmitter, a driver, a charger, and an outputter. The transmitter transmits a reference alternating current signal. The driver is connected to the transmitter and a sensing node and outputs a node current signal. The charger is connected to the sensing node and generates a magnetic field. The outputter is electrically connected to an output terminal and outputs a sensing signal.

Abstract: A touch panel includes a first touch electrode disposed on a base substrate and a second touch electrode disposed on an insulating layer, which is disposed over the first touch electrode. The first touch electrode includes a first linear pattern disposed along a first direction and a first protrusion pattern extending from the first linear pattern. The second touch electrode includes a second linear pattern disposed along a second direction crossing the first direction and a second protrusion pattern extending from the second linear pattern. Wires connect the first touch electrode and the second touch electrode to a driving circuit. The second protrusion pattern partially overlaps the first protrusion pattern.
