Patent number: 10429567Abstract: A multi-view pixel directional backlight module and a naked-eye 3D display device are provided. The multi-view pixel directional backlight module includes at least two rectangular light guide plates closely stacked together. A light-emerging surface of the rectangular light guide plate is provided with multiple pixel arrays. Light emitted by pixels in a same pixel array is pointed to a same viewing angle, and different pixel arrays have different viewing angles.

Publication number: 20140233126Abstract: A reflective color filter comprises a medium grating layer (220), a metal layer (230), and a first medium layer (240). The metal layer is provided on the ridge portion, at least one side portion, and a part of the groove portion of the medium grating layer. The first medium layer reflecting outside light is provided on the medium grating layer and the metal layer. Because a part of the medium grating layer is exposed through an opening of the metal layer on the groove portion, the angular sensitivity of the resonance output is reduced, and the influence of the incident angle on the resonance condition is diminished. Therefore, a reflection filtering can be realized in a wide angular area.Type: ApplicationFiled: May 31, 2011Publication date: August 21, 2014Applicants: SUZHOU UNIVERSITY, SVG OPTRONICS, CO.
