A display device includes a display panel and a driving connector connected to the display panel and from which driving signals are provided to the display panel, the driving connector including a driving integrated circuit, a gate pad through which a first driving signal is output from the driving connector to the display panel, a first input pad through which the first driving signal is input to the driving connector from outside thereof, and a gate driver which connects the gate pad to the first input pad and includes a first substrate and a transistor on the first substrate and including a source electrode connected to the first input pad and a drain electrode connected to the gate pad. Within the driving connector, the transistor and the driving integrated circuit are in order from the first substrate.

Driving connector and display device including the same

A display device including: a display panel including a plurality of pixels; an input sensor disposed on the display panel and including detection electrodes; a data driving circuit configured to output data signals or detection driving signals; and a selection circuit configured to provide the data signals to the plurality of pixels in response to a first enable signal and provide the detection driving signals to the detection electrodes in response to a second enable signal.

Display device

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.
