  • Patent number: 9443483
    Abstract: A multi-domain liquid crystal display is disclosed. The display includes embedded fringe field amplifiers behind the color dots of the display. Specifically, the embedded fringe field amplifiers have a polarity that is different from the polarity of the color dot, that is located in front of the embedded fringe field amplifier. This difference in polarity enhances the fringe fields of the color dot or in some situations may create additional fringe fields. The enhanced fringe fields or additional fringe fiends enhances the performance of the display.

  • Publication number: 20160195779
    Abstract: A vertically aligned liquid crystal display is disclosed. The liquid crystal display, which has a first substrate and a second substrate, uses pixels having vertical riser above the first substrate, a pixel electrode having a large gap region on the first substrate and a sidewall region over a sidewall of the vertical riser, a common electrode below the second substrate, liquid crystals between the pixel electrode and the common electrode, and a switching element coupled to the pixel electrode. A large gap distance between the large gap region of the pixel electrode and the common electrode is at least one and a fifth times as long as a sidewall gap distance between the sidewall region of the pixel electrode and the common electrode. The elevation of the sidewall region of the pixel electrode amplifies an intrinsic fringe field around the pixel electrode. The amplified intrinsic fringe field interacts with the pixel electrode electric field and causes the liquid crystals to tilt in the same direction.

    Abstract: A vertically aligned liquid crystal display is disclosed. The liquid crystal display, which has a first substrate and a second substrate, uses pixels having a pixel electrode on the first substrate, a common electrode under the second substrate, liquid crystals between the pixel electrode and the common electrode, a switching element coupled to the pixel electrode, a control electrode above the first substrate on a first side of the pixel electrode. When the pixel is in an ON state, the control electrode is at an active control voltage, which is greater than the output voltage of the first switching element. The difference in voltage in the control electrode and the pixel electrode amplifies an intrinsic fringe field around the pixel electrode. The amplified intrinsic fringe field interacts with the pixel electrode electric field and causes the liquid crystals to tilt in the same direction.

  • Patent number: 8830430
    Abstract: A multi-domain vertical alignment liquid crystal display using fringe field amplification is disclosed. Each pixel is subdivided into color dots. Further more each pixel contains extra-planar fringe field amplifiers that separate the color dots of a pixel. The voltage polarity of the color dots and extra-planar fringe field amplifiers are arranged so that fringe fields in each color dot causes multiple liquid crystal domains in each color dot. Specifically, the color dots and the extra-planar fringe field amplifiers are arranged so that neighboring polarized elements have opposite polarities. The performance of the display is further enhanced by using a sliced common electrode having common electrode slices over the color dots.

  • Patent number: 8605239
    Abstract: A display unit with interleaved pixels is disclosed. A first pixel of the display unit includes a first first-pixel electrode that is adjacent to multiple color dots of a second pixel. By driving the polarity of the first first-pixel electrode to a first polarity and the color dots of the second pixel to a second polarity, the fringe fields of the color dots of the second pixel are enhanced.

  • Patent number: 8471971
    Abstract: A multi-domain liquid crystal display is disclosed. The display includes embedded polarity regions within the color dots of the display. Specifically, the embedded polarity regions have a polarity that is different from the polarity of the color dot containing the embedded polarity region. This difference in polarity enhances the fringe fields of the color dot or in some situations may create additional fringe fields. The enhanced fringe fields or additional fringe fiends can more quickly restore liquid crystals to their proper position.

  • Patent number: 8467019
    Abstract: Displays using a low cost method to implement switching element point inversion driving schemes while using integrated circuits that are designed to implement switching element row inversion or switching element column driving schemes are described. In one display, a first color dot is on a first side of a control line and a second color dot is on a second side of the control line. A first switching element is coupled to the first control line and the first color dot and a second switching element is coupled to the second color dot and the control line. Thus the control line controls color dots on two different rows or two different columns.

  • Patent number: 8319918
    Abstract: A multi-domain vertical alignment liquid crystal display that does not require physical features on the substrate (such as protrusions and ITO slits) is disclosed. Each pixel of the MVALCD is subdivided into color components, which are further divided into color dots. The polarity of the color dots are arranged so that fringe fields from adjacent color dots causes multiple liquid crystal domains in each color dot. Specifically, the color dots of a pixel are arranged so that each color dot of a first polarity has four neighboring pixels of a second polarity. Thus, a checkerboard pattern of polarities is formed. Furthermore, the checkerboard pattern is extended across multiple pixels in the MVALCD. In addition, many display unit include multiple pixel designs to improve color distribution or electrical distribution.
