  • Patent number: 7724332
    Abstract: Transflective liquid crystal display devices and fabrication methods thereof. A single cell gap transflective liquid crystal display device includes a first substrate with a reflective region and a transmissive region. A second substrate opposes the first substrate. A liquid crystal layer is disposed between the first and second substrates. A reflective structure is disposed on the first substrate, thereby forming a recess at the transmissive region. A first alignment layer is conformably formed on the first substrate covering the reflective structure, thereby forming a second recess at the reflective region. The second recess is filled with a second alignment, wherein the first and second alignment layers provide different orientations and pre-tilt angles for the liquid crystal layer.

  • Publication number: 20060285056
    Abstract: A wide viewing angle liquid crystal display is provided. It changes the contents of spacers to produce non-homogeneous and symmetric electrical field by embedding conducting particles in the spacers. The liquid crystal display device includes a first substrate, a second substrate, optical films, electrodes, alignment layers and a liquid crystal layer sandwiched by the first and the second substrates. The space between the two substrates further includes plural spacers, where conducting particles are embedded in the spacers. The conducting particles can be embedded directly inside the commercial spacers. The spacers with embedded conducting particles can also be formed by adding a certain ratio of conducting particles in the spacer material during manufacture process. Properly allocating the spacers can optimize the wide viewing angle effect.

  • Publication number: 20060103784
    Abstract: A chromatic flexible display with a wide viewing angle and a method for manufacturing the same are proposed. The present invention provides a wide-angle structure for a chromatic flexible display and a corresponding manufacturing method. Due to the arrangement of the microstructures of the upper plastic base plate and the lower plastic base plate, the colorization is improved and the viewing angle is widened and has multiple divisions. In this way, the chromatic flexible display provided in the present invention is convenient for mass production and displays a high-quality image with a wide viewing angle.

  • Publication number: 20060044494
    Abstract: A transflective liquid crystal display device and, manufacturing method for the same are described. Two kinds of liquid crystals with different ?n values are injected into a reflective region and a transmissive region in a transflective liquid crystal display respectively. If the value ?n of the transflective region is double that of the reflective region, the present, invention provides its optimal optical design in a signal cell gap of the transflective liquid crystal display.
