  • Patent number: 9285598
    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.

  • Patent number: 9081225
    Abstract: Provided is a liquid crystal display device which is capable of eliminating a non-display region at a peripheral edge of a display screen, and displaying an image on the entire surface thereof. A backlight unit (22) emits parallel rays. The liquid crystal panel (24) transmits the parallel ray as a unit parallel ray in pixel unit, thereby forming an original image. An image enlarging panel (26) is an optical element having a flat-plate shape. The image enlarging panel (26) causes the unit parallel ray of each pixel to obliquely travel by refraction to shift a position of the unit parallel ray in a flat-plate plane, to thereby forms a display image enlarged the original image. A viewing angle enlarging panel (28) expands an angular distribution of the entering unit parallel ray from the image enlarging panel (26), thereby enlarging a viewing angle of the display image.
