  • Publication number: 20140347411
    Abstract: There is provided a driving method for a display, which includes a display unit and a phase modulation unit. The display unit includes a plurality of pixel rows and generates image signals having a polarization direction. The phase modulation unit includes two oppositely disposed electrodes and an LC layer sandwiched between the two electrodes. The driving method changes a potential difference provided on the two electrodes of the phase modulation unit to control the twist of the LC layer thereby changing the polarization direction of the image signals generated by the display unit and passing through the phase modulation unit.

  • Publication number: 20140333860
    Abstract: A three-dimensional (3D) display installation is disclosed. The installation comprises a display, a phase-modulation device and at least a pair of polarized glasses. The phase-modulation device is set in one side of the display panel. The driving frequency of the display panel and the phase-modulation are above 120 Hz and synchronous with each other. The modulated polarized light contains left eye and right eye signals in sequence, which can be filtered by polarized glasses alternatively, and then the 3D visual effect is achieved. The 3D installation is suitable for multiple viewers at the same time, and the resolution of the screen is also unchanged under the 3D display mode.

  • Publication number: 20120086707
    Abstract: A phase switch component driven synchronously is configured at a light emitting side of a display panel of a display. A plurality of parallel electrodes is disposed on a conductive film of the phase switch component, each corresponding to one of a plurality of rows of display pixel driven by gate drivers of the display panel. When the display panel sequentially drives the pixel electrodes of each row of display pixel, by line scanning way, to output frames of 3-dimension images, the phase switch component is synchronously driven to switch the phase of liquid crystals by each parallel electrodes and alters the frames to be polarized lights capable of being received by a left part and a right part of 3D glasses respectively.

  • Publication number: 20120081639
    Abstract: A liquid crystal display device includes a first polarization plate, a first birefringent film atop the first polarization plate, an optically compensated bend mode (OCB-mode) cell atop the first birefringent film, a refractive film atop the OCB-mode cell, a second birefringent film atop the refractive film, and a second polarization plate atop the second birefringent film. With this structure, any phase retardation of polarized light occurred during the propagation of the polarized light from the first polarization plate to the second polarization plate is compensated by the first birefringent film, the refractive film, and the second birefringent film and a substantially cross-shaped radiation pattern of full viewing angle is obtained in an actual measurement at the light outgoing surface of the liquid crystal display device, proving the liquid crystal display device has effectively improved the problem of restricted viewing angle and provides good optical performance.
