Abstract: A display device includes: a touch panel including a touch area including first touch electrodes and second touch electrodes; and a touch panel driver for providing touch driving signals to the first touch electrodes. The touch panel driver provides the touch driving signals to the first touch electrodes in a first touch sensing period of a first mode, operates in a second mode when the first touch is detected, and provides the touch driving signals to the first touch electrodes disposed in a first row area of the touch area in which the first touch is detected in a second touch sensing period of the second mode.

Abstract: A sensor device includes sensing areas, first sensor electrodes and second sensor electrodes forming capacitors at intersections of the first and second sensor electrodes, and a sensor driver time-divisionally senses each of the sensing areas once during a first sensing frame period, time-divisionally senses each of the sensing areas once during a second sensing frame period, and sets an initial sensing area to be sensed during an initial second sensing period of the second sensing frame period to be different from a last sensing area sensed during a last first sensing period of the first sensing frame period.

Abstract: A display device includes a display panel having a display portion. A window is disposed above the display portion. The window includes a display area, on which a screen is displayed by the display portion, and a non-display area, disposed around the display area. The non-display area of the window includes a sensing portion and a non-sensing portion. The non-display area of the window includes a first light shielding member. The sensing portion includes a first conductive layer and a second conductive layer stacked on the first conductive layer with the first light shielding member interposed therebetween.

Abstract: A display device includes a display panel; a pressure sensor disposed on the display panel; and a lower bracket. The pressure sensor is disposed between the display panel and the lower bracket and is disposed on the lower bracket. The pressure sensor includes a first substrate, a first pressure sensing layer disposed between the first substrate and the lower bracket, a first driving electrode disposed between the first pressure sensing layer and the lower bracket, and a first sensing electrode spaced apart from the first driving electrode. A gap is present between the first pressure sensing layer, and the first driving electrode and the first sensing electrode.

Abstract: A display device includes a display panel configured to display an image. A window laces the display panel and includes a transparent display area configured to transmit the image displayed on the display panel therethrough. A non-display area at least partially surrounds the display area. A light-blocking pattern layer is disposed on the non-display area of the window. A touch member is disposed between the display panel and the window and includes a voltage line. A pressure sensing wiring is disposed between the touch member and the window and at least partially overlaps the voltage line. The voltage line and the pressure sensing wiring overlap the light-blocking pattern layer.
