Abstract:
A display device may include a display panel, a sensor unit, and a touch driver. The sensor unit is provided on the display panel and may output a sensing signal corresponding to a touch input. The sensor unit may include a first electrode and may include a conductive layer provided between the display panel and the first electrode and spaced from the first electrode. The touch driver may include a signal receiver. The signal receiver may include a first input terminal electrically coupled to the first electrode, may include a second input terminal electrically coupled to the conductive layer, may receive the sensing signal, and may output a signal corresponding to a voltage difference the first input terminal and the second input terminal.
