  • Patent number: 5365284
    Abstract: In a liquid crystal display device for receiving television signals by an interlace scanning method, number of the rows of pixels and of scan signal lines on a liquid crystal panel is increased to be the same as the number of valid scan lines of 1 frame of television signals. The original video signals to be inputted to the device are compressed to 1/2, and interpolating signals are added to every line of the compressed signals to form pseudo video signals. Shift register operation of a scan driver and the segment driver are done twice as fast as that in the conventional device, and start timing of the shift register operation of the segment driver is controlled to be shifted by 1/2 horizontal scanning period between the even field and odd field, while the pseudo video signals are applied to the segment driver.

  • Patent number: 5057928
    Abstract: The invention relates to a drive apparatus for a liquid crystal display device. The voltage, to be applied to longitudinally and latitudinally arranged liquid crystal cells of the liquid crystal display device, is altered in polarity from field to field and from frame to frame, whereby the occurrence of flicker is prevented. The field discriminating device counts the numbers of lines in first and second fields by synchronizing a vertical synchronizing signal at a leading point of a field time. Thereafter the difference in the number of lines between the first and second fields is detected, the field times being thereby discriminated. When a video signal is erroneous, the field discriminating device provides a field discriminating signal, the level of which is changed alternately from field time to field time.

  • Patent number: 4365242
    Abstract: A new driving technique is disclosed for a liquid crystal display panel for displaying at least two rows of characters and a cursor line while scanning scanning lines of the panel, which technique can decrease the number of scanning lines and increases the above defined voltage margin by scanning the scanning lines each two rows at a time in a line sequential scanning fashion and skipping the scanning of a cursor line electrode in a row where a display of the cursor line is unrequired, thus ensuring good contrast and viewing angle characteristics of the panels.

  • Patent number: 4338598
    Abstract: A thin-film EL display panel has a plurality of scanning side electrodes and a plurality of data side electrodes. The thin-film EL display panel is excited to emit light through a pre-charge mode, a discharge modulation mode and a write mode. A voltage lower than a modulation voltage is supplied from the data side electrodes to the thin-film EL display panel as a first pre-charge voltage. Thereafter, a difference voltage between the first pre-charge voltage and the modulation voltage is supplied from the scanning side electrodes to the panel as a second pre-charge voltage, thus reducing power consumption to a minimum during the pre-charge mode.
