  • Patent number: 7177002
    Abstract: Pixel regions are formed on a liquid-crystal-side surface of one substrate out of respective substrates which are arranged to face each other in an opposed manner with liquid crystal therebetween, wherein each pixel region includes pixel electrodes having bent portions and counter electrodes which are arranged at positions where the pixel electrodes are shifted in parallel, the pixel electrode and the counter electrode are respectively constituted of two electrodes which are overlapped to each other as an upper layer and a lower layer by way of an insulation film, and to the lower-layer side electrode of at least one electrode out of the pixel electrode and the counter electrode, projections which further project from crests of convex-portion sides of the bent portions and extend toward another electrode side are provided.

  • Patent number: 6542141
    Abstract: A liquid crystal halftone display system including a tone generator which, for pixels having P tones of K tones (1≦P≦K), alternately outputs first N-bit tone display data and second N-bit tone display data in successive frames at one of a first phase and a second phase. Within a block of pixels, the tone generator alternately inverts the phase of the N-bit tone display data at successive first pixels having different ones of the P tones within the block of pixels beginning at a left side of the block of pixels, and alternately inverts the phase of the N-bit tone display data at successive pixels having a same one of the P tones within the block of pixels beginning at the left side of the block of pixels.

  • Patent number: 6072451
    Abstract: A liquid-crystal display system includes a data driver, a scan driver, a liquid-crystal panel, a line memory (204 in FIG. 2) in which input display data (101) for representing any of display-ON, display-OFF and halftone every pixel are stored for, at least, one line, and a halftone pattern generator (200) by which liquid-crystal display data (106) to be applied to the data driver are generated using the contents of the line memory and the input display data.

  • Patent number: 5109500
    Abstract: A disk control unit for writing data on or reading the same from a disk in a disk apparatus in response to an instruction from a host computer. The disk control unit has a plurality of command buffers for storing a group of operation information and operation length information corresponding to individual fields in the disk format of the disk apparatus. Prior to processing the length information is set in a counter and then is counted decrementally with progress of the processing steps, whereby an operation end signal is produced to control an address generator for the command buffers. The disk control unit also has a pointer register for storing a jump point address in response to indication of the operation information and outputting the stored address in response to indication of the other operation information to change the address of the address generator.
