摘要： 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. Consequently, to the rows of pixels to which original video signals are applied in the even field and to the rows of pixels to which interpolating signals are applied in the even field, interpolating signals and original video signals are applied in the odd field, respectively. Consequently, display can be carried out seemingly in accordance with the interlace scanning method.

摘要： A circuit for driving a liquid crystal panel using a plurality of source drivers includes a separate line memory circuit for transmitting color signals to the even and odd line source drivers, respectively. Each line memory circuit includes digital color signal train forming circuits arranged according to a color order of the corresponding source lines upon receipt of analog color signals of the three colors in parallel, memories for successively storing the digital color signal train, circuits for alternately reading a first and second half memory area and circuits for latching and converting the read digital color signals in a prescribed order, to analog color signals of the three signals in parallel and transmitting the analog color signals to the corresponding source drivers.
