    Abstract: A display device may include a sensor layer, a substrate, a pixel layer, and a black matrix. The sensor layer may include photo sensors. The substrate may be positioned on the sensor layer. The pixel layer may be positioned on the substrate and may include pixels. The substrate may be positioned between the sensor layer and the pixel layer. The pixels may include pixel electrodes. The black matrix may be positioned on the pixel layer, may include first-set openings respectively overlapping with the pixel electrodes, and may include second-set openings not overlapping with any pixel electrodes of the display device in a direction perpendicular to the substrate. The pixel layer may be positioned between the substrate and the black matrix.

    Abstract: A method for driving an optical modulation device is provided. The optical modulation device includes first and second portions. Each of the first and second portions includes a first plate, a second plate opposite to the first plate, and a liquid crystal layer disposed between the first and second plates. The method includes forming a forward phase gradient in the first portion by applying a first driving signal to first and second electrodes in the first plate of the first portion and a third electrode in the second plate of the first portion. The method further includes forming a reverse phase gradient in the second portion by applying a second driving signal differing from the first driving signal to fourth and fifth electrodes in the first plate of the second portion and a sixth electrode in the second plate of the second portion.
