Abstract
A display apparatus is disclosed which comprises a plurality of layers arranged in a light emitting direction of a light source, wherein a diaphragm layer configured to enhance an emitting brightness of the display apparatus is arranged on one of the plurality of layers. With such diaphragm layer in the display apparatus, the brightness of the display apparatus can be enhanced by the Fresnel diffraction effects of the diaphragm layer. In the 2D display, for a same brightness, the power consumption in the display apparatus may be reduced. In the 3D display, the brightness of the display apparatus may be improved and the crosstalk may be reduced.
