Abstract: A display device includes a display layer disposed on a substrate. The display layer includes a light emitting elements. A sensor is disposed on the display layer. Sensing lines of the sensor are disposed outside touch electrodes of the sensor and are electrically connected to the touch electrodes. A gesture sensor electrode of the sensor is disposed outside the sensing lines. In a plan view, the gesture sensor electrode does not overlap a conductor which provide a constant voltage to the light emitting elements.

Abstract: A display device includes: a substrate; a display layer on the substrate; and a touch layer on the display layer, and including: a touch area; first sensor electrodes located along a first direction, and electrically connected to each other; second sensor electrodes located along a second direction crossing the first direction, and electrically connected to each other; and third sensor electrodes located along the first direction, and electrically insulated from the first and second sensor electrodes. In a first mode, the touch layer is to sense amounts of change in first capacitances between the first sensor electrodes and the second sensor electrodes, and in a second mode, the touch layer is to sense amounts of change in second capacitances between the first sensor electrodes and some of the second sensor electrodes, and amounts of change in third capacitances between the first sensor electrodes and the third sensor electrodes.

Abstract: A display device includes a light sensing array layer (LSAL), a substrate, a selective light transmission layer (SLTL), a pixel circuit layer (PCL), a display element layer (DEL), and pixels. The LSAL includes an optical sensor to sense incident light. The substrate is on the LSAL and includes a display area (DA) including pixel areas (PAs), and a non-DA adjacent to the DA. The SLTL is disposed on the substrate and includes through-holes to form a path of light onto the optical sensor, and a light-blocking conductive pattern (LBCP) between the through-holes. The PCL is disposed on the SLTL and includes a conductive layer and an insulation layer. The DEL is disposed on the PCL and emits light. Each pixel includes a pixel circuit disposed on the PCL, and a light emitting element on the DEL in a corresponding pixel area. The LBCP is electrically connected to the conductive layer.

Abstract: An operating method of a touch sensor includes sensing first touch intensities in a first touch-sensing area by using first touch cells, sensing second touch intensities in a second touch-sensing area that is adjacent to the first touch-sensing area by using second touch cells each having an area that is smaller than that of each of the first touch cells, grouping some second touch cells among the second touch cells as a touch-sensing group having a same area as one of the first touch cells, calculating a representative touch intensity of the touch-sensing group by using the second touch intensities sensed by second touch cells in the touch-sensing group, and detecting a touch position by using the first touch intensities and the representative touch intensity.
