    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 projection image display device includes, a light source, an image display panel having a number of pixels and a vertical scanning function, an optical system for dividing light from the light source into a plurality of lights of different wave ranges and directing and overlapping the divided plural lights onto an area from different directions, a light-collector for collecting each of the plural divided lights directed onto the area by the optical system into apertures of pixels of the image display panel corresponding to the wave range of the light, a projector for projecting an image displayed on the image display panel, and a color-changer for mutually changing, at every vertical scanning of the image display panel, the directions in which the optical system directs the plural divided lights of the different wave ranges, so as to mutually change the wave ranges of light directed to the pixels of the image display panel sequentially. The image display panel displays an image with each of the pixels displaying a color of the wave range of light directed to the pixel at every change by the color-changer.
