Abstract: An electronic device includes a display layer configured to display an image, a sensor layer disposed on the display layer and including a plurality of first electrodes and a plurality of second electrodes, and a sensor driver configured to drive the sensor layer and selectively operate in a first mode or a second mode different from the first mode. When operating in the second mode, the sensor driver is configured to selectively operate in a first driving mode to simultaneously output a plurality of first transmission signals to the plurality of first electrodes or in a second driving mode to simultaneously output a plurality of second transmission signals different from the plurality of first transmission signals to the plurality of first electrodes.

Abstract: An electronic device includes a display layer that displays an image during a plurality of frame periods, a sensor layer, a sensor driving unit, and a main driving unit. When a user makes a call, the sensor driving unit switches from a first mode to a second mode and drives the sensor layer. When the sensor layer senses a large-area conductor in the second mode, the sensor driving unit switches from the second mode to a third mode and drives the sensor layer. When the main driving unit determines a proximity state in the third mode, the sensor driving unit switches from the third mode to the second mode and drives the sensor layer. When the sensor layer senses a touch in the second mode, the sensor driving unit switches from the second mode to a fourth mode and drives the sensor layer.

Abstract: An electronic device includes a display layer including a pixel within an active region and a sensor, a sensor layer, a display driving circuit, a sensor driving circuit, and a main driving circuit to operate in a first mode. In the first mode, the display driving circuit emits a first light through a light emitting element of the pixel disposed in a first region of the active region, the display driving circuit receives a second light reflected based on the first light, through a sensing element of the sensor disposed in the first region and a second region surrounding the first region, and the main driving circuit determines whether the display layer and the sensor layer are placed in a pocket of a user, based on an amount of the second light.

Abstract: An apparatus for generating a gray scale voltage in an organic light emitting display device is disclosed. In one aspect, the apparatus includes a gamma reference voltage generator, a gray scale voltage output unit and a gray scale voltage selector. The gamma reference voltage generator outputs a gamma reference voltage. The gray scale voltage output unit outputs N first gray scale voltages, based on the gamma reference voltage. The gray scale voltage selector has a lookup table in which voltage values respectively corresponding M reference gray scales are previously set, and outputs second gray scale voltages by selecting M of the N first gray scale voltages.
