  • Patent number: 6246399
    Abstract: An active matrix liquid crystal display consuming only a small amount of electric power. The liquid crystal display has two driver circuits which drive two sets of signal lines, respectively, One set of signal lines creates the upper half of a frame of image displayed on the viewing screen, while the other set of signal lines creates the lower half of the image. An image signal for creating the frame of image is supplied to the two driver circuits alternately so that when one of the driver circuits is operating, the other is halted or put on standby.

  • Patent number: 5654733
    Abstract: An active matrix liquid crystal electrooptical device consuming only a small amount of electric power without producing flicker. The electrooptical device comprises a plurality of pixels arranged in rows and columns. Each pixel has a switching element. Scanning lines for turning on and off the switching elements and signal lines to which display signals are produced are connected with the pixels. The device further includes plural signal line driver circuits. Each driver circuit produces a display signal to the corresponding signal line. Each display signal exhibits one polarity during one frame period. The polarity of the display signal produced by at least one of the driver circuits is different from the polarity of the display signal produced by the other driver circuit. The polarity is inverted every frame. The signal lines connected with any one of the driver circuits are connected with the pixels which are, in turn, connected with one of the scanning lines.
