Patent number: 8928824Abstract: A polarizer film is used for converting polarized light from a backlight module into light along a first direction. Multiple electrodes are disposed on a transparent substrate. Each electrode extends along a second direction different from the first direction. An alignment of liquid crystal molecules varies according to voltage applied on the electrodes. A retard unit is disposed between the transparent substrate and the polarizer film and used for converting the polarized light into light along a third direction different from the first and second direction. A polarization direction of the emitted light is perpendicular to an alignment of an electrode layer. In this way, an optical axis of the liquid crystal molecules matches the polarization direction of the light from the retard unit when voltage is not applied. So, the maximal lens power is attained with decreasing the cost resulted from the decreased thickness of the liquid crystal layer.Type: GrantFiled: November 16, 2012Date of Patent: January 6, 2015Assignee: Shenzhen China Star Optoelectronics Technology Co., Ltd.Inventors: Chih-Wen Chen, Chia-Chiang Hsiao

Patent number: 8928823Abstract: The present invention discloses a 3D display device adopting a half-source driving structure. The 3D display device includes a liquid crystal display panel. Gate lines and data lines of the liquid crystal panel are crossed with each other and define multiple pixel regions. Each gate line is bent to have a plurality of arched portions that each arched portion corresponds in position to one pixel region and forms an accommodating area. A switching element in each one of the pixel regions is mounted in the corresponding accommodating area and connected to a pixel electrode. Because the accommodating areas formed by the gate lines can accommodate switching elements, light-exiting positions of the pixel electrodes in adjacent pixel regions can be in line with each other to avoid a color washout problem when the phase retarder film is mounted with a positional error.Type: GrantFiled: May 7, 2012Date of Patent: January 6, 2015Assignee: Shenzhen China Star Optoelectronics Technology Co.
