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: A display device includes a display panel, an input sensor having a plurality of first sensing electrodes and a plurality of second sensing electrodes, and a readout circuit that includes a noise filter electrically connected to the plurality of first sensing electrodes and the plurality of second sensing electrodes to remove noise of a receiving signal received from the plurality of first sensing electrodes and the plurality of second sensing electrodes. The readout circuit determines which of the first sensing electrodes are influenced by a touch based on the receiving signal as influenced electrodes, during a first sensing mode. The readout circuit adjusts a passband of the noise filter based on the number of influenced electrode and transmits a transmitting signal to the influenced electrodes, during a second sensing mode.
