Abstract
A display apparatus including a first substrate, a second substrate opposite to the first substrate, a pixel array disposed between the first substrate and the second substrate and a photoelectric conversion array disposed between the pixel array and the second substrate is provided. The pixel array includes sub-pixel units. An initial light from each of the sub-pixel units is converted into an electrical energy and a display light by the photoelectric conversion array. The electrical energy is stored and the display light passes through the second substrate to display an image. Display lights presented by two adjacent sub-pixel units have different wavelengths. The photoelectric conversion array includes photoelectric conversion cells. An area of each of the photoelectric conversion cells covers the two adjacent sub-pixel units and partially overlaps an area of another photoelectric conversion cell. Different photoelectric conversion cells covering the same sub-pixel unit have different absorption wavelengths.
