<p>A liquid crystal display device receiving television signals formed in accordance with interlace scanning method for displaying images is disclosed. Numbers 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.</p> |
