  • Publication number: 20100014039
    Abstract: The invention is directed to an improved flat panel liquid crystal display (LCD). In one embodiment the improved LCD includes a liquid crystal layer that completely fills a gap formed between a color filter array and a thin film transistor (TFT) array. The TFT array includes a substrate that includes one or more pixel areas. Each pixel area may be divided into at least two pixel sub-areas. Each pixel sub-area is configured to have a different electric field than its counterparts, such that mutual compensation in the sub-areas decreases distortion of a gamma curve and improves lateral visibility of the flat panel display. In one embodiment, a first pixel electrode is formed in a first of the at least two pixel sub-areas; and a second pixel electrode is formed in a second of the at least two pixel sub-areas.

    Abstract: An array substrate includes first and second gate lines, a data line, a pixel electrode, a domain electrode, first, second and third switching elements, and a voltage-changing part. The domain-dividing electrode divides the first and second pixel parts into a plurality of areas. The first, second and third switching elements are controlled by a first gate signal applied from the first gate line. The first, second and third switching elements apply a data signal received from the data line to the first and second pixel parts and the domain-dividing electrode, respectively. The voltage-changing part is controlled by a second gate signal applied from the second gate line. The voltage-changing part increases a voltage level of the domain-dividing electrode and decreases a voltage level of the second pixel part.
