  • Patent number: 7605884
    Abstract: A TFT array panel on which both pixel electrodes and common electrodes are formed and a color filter panel is disposed opposing the array panel, and liquid crystals are interposed therebetween. The liquid crystals are aligned parallel to the two panels and driven by parallel electric field formed between the pixel electrodes and reference electrodes. Polarization films are arranged outsides the two panels, and a quasi-A plate compensation film is arranged between the color filter panel and the polarization film.

  • Publication number: 20070195410
    Abstract: In a stereoscopic image conversion panel for enhancing display quality and a stereoscopic image display apparatus having the panel, the stereoscopic display panel includes lower and upper transparent substrates, lower and upper transparent electrodes, and a liquid crystal lens layer. The lower and upper transparent substrates face each other. The lower transparent electrodes are disposed on the lower transparent substrate, formed along a first direction, and formed substantially in parallel with each other along a second direction. The upper transparent electrodes are disposed on the upper transparent substrate, formed along the second direction, and formed substantially in parallel with each other along the first direction. The liquid crystal lens layer is disposed between the upper and lower transparent substrates, and a longitudinal arrangement direction of liquid crystal molecules of the liquid crystal lens layer is changed by an electric field to have a predetermined refractive index.

  • Publication number: 20070024781
    Abstract: A display panel assembly includes a display panel, a first polarizing plate disposed over the display panel, a second polarizing plate disposed under the display panel, and a polarization compensation film disposed over the first polarizing plate. The polarization compensation film includes a polarization prism film and a phase difference film. The polarization prism film divides a natural light wave into an ordinary wave with a first polarization state, and an extraordinary wave with a second polarization state. The phase difference film changes the second polarization state of the extraordinary wave into the first polarization state.
