  • Publication number: 20080007664
    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.

  • Publication number: 20080002109
    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 MVA LCD is subdivided into color components, which are further divided into color dots. The polarities of the color dots are arranged so that fringe fields in each 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 MVA LCD. In addition, many display unit include multiple pixel designs to improve color distribution or electrical distribution. Furthermore, many display units interleave the pixels.

  • Publication number: 20080002072
    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 MVA LCD is subdivided into color components, which are further divided into color dots. The drive component areas, i.e. where switching elements and storage capacitors are located, are converted to associated dots by adding an electrode that can be electrically biased. The voltage polarity of the color dots and associated dots are arranged so that fringe fields in each color dot causes multiple liquid crystal domains in each color dot. Specifically, the color dots and associated dots of a pixel are arranged so that associated dots have opposite polarity as compared to neighboring color dots.

  • Publication number: 20070200986
    Abstract: A liquid crystal display includes a liquid crystal layer between a first substrate and a second substrate, at least one first-type optical compensation layer over the liquid crystal layer, and at least one polarizer layer over the first-type optical compensation layer. The liquid crystal layer has a birefringence liquid crystal material. The first-type optical compensation layer includes a negative birefringence material. The optical axis of the first-type optical compensation layer is substantially parallel to a plane of either of the first substrate or the second substrate throughout the the layer. A liquid crystal display is prepared by forming a liquid crystal layer as described above, forming at least one first-type optical compensation layer as described above, and forming at least one polarizer layer over the first-type optical compensation layer.

  • Publication number: 20070202253
    Abstract: A method to form alignment layers on a substrate of an LCD is disclosed. The substrate is placed in a vacuum chamber and undergoes a purging process. The purging process heats the substrates and removes water vapor from the vacuum chamber. Specifically, the vacuum chamber is evacuated to a low pressure and refilled with a preheated inert gas. Evacuation of the vacuum chamber and refilling of the vacuum chamber is repeated several times. The alignment layer is then deposited using vapor deposition. Alternatively, plasma enhanced vapor deposition can be used for depositing the alignment layer. Furthermore, plasma cleaning prior to the deposition of the alignment layer can used clean the substrate.

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.

  • Publication number: 20070013849
    Abstract: A particular multi-domain vertical alignment (MVA) liquid crystal display (LCD) can offer a high contrast ratio and a wide symmetrical viewing angle, without rubbing, protrusion surface, or ITO slit geometry. The viewing angle can be further enlarged by the use of optical compensation films, such as a negative birefringence anisotropic optical film with a vertical optical axis.

  • Publication number: 20050270457
    Abstract: A microdisplay including a light-transmissive active circuit layer, the active circuit layer having an optical birefringence value that contributes to an asymmetrical viewing space and an optical compensator to compensate for the optical bireflingence value of the active circuit layer. The optical compensator can include a retardation film, a c-plate, and/or a passive circuit layer. The passive circuit layer can be fabricated to equivalent specifications of the active circuit layer.
