  • Active matrix for liquid crystal displays in which a data bus consists of two data subbuses and each data subbus is separated from an adjacent data bus by one display electrode
    Patent number: 5715025
    Abstract: An active matrix for liquid crystal displays having a plurality of picture elements, a plurality of address buses, and a plurality of data buses orthogonal to the address buses. Each address bus includes a pair of address subbuses spaced from one another, and each data bus includes a pair of data subbuses spaced from one another. Each picture element includes a pair of display electrodes, and each data subbus is separated from the other by at least one display electrode. Each picture element of an active matrix liquid crystal display includes a pair of display electrodes wherein the position of the pair of display electrodes representing a color on one row of the picture elements is laterally shifted by at least one display electrode with respect to the position of the pair of display electrodes representing a different color on an adjacent row to form a triangular structure representing the color picture element between the adjacent rows.

  • Active matrix for liquid crystal displays having two switching means and discharging means per pixel
    Patent number: 5479280
    Abstract: An active matrix for liquid crystal displays having a plurality of picture elements, a plurality of address buses to which an address signal having a high signal level and a low steady state signal level is applied, and a plurality of data buses orthogonal to the address buses. Each picture element includes at least one display electrode device; a first switching device coupled between the display electrode device and a first respective one of the address buses and a respective one of the data buses; and a second switching device coupled between the display electrode device and a second respective one of the address buses and the respective data bus. The second switching device includes a device for preventing the display electrode from discharging whereby a substantially same voltage is maintained at the display electrode during the time when the address signal changes from the high level to the low level.

  • Active matrix liquid crystal displays having diodes connected between second transistors and second data buses
    Patent number: 5473451
    Abstract: An active matrix for liquid crystal displays having a plurality of picture elements, a plurality of address buses, and a plurality of data buses orthogonal to the address buses. Each picture element includes at least one display electrode; a first switching device coupled between the display electrode and a first respective one of the address buses and a first respective one of the data buses; and a second switching device coupled between the display electrode and a second respective one of the address buses and a second respective one of the data buses, the second switching device including a device for preventing the display electrode from discharging whenever the second respective data bus becomes defective.
