Title: Liquid crystal display device, its driving method and driving circuit
Inventor: KAI TSUTOMU
IPC: G09G3/36
Filed: 1994-03-18
Abstract: PURPOSE:To expand the horizontal or vertical direction or both directions of a display area even by a nonintegral multiple value according to the size of a display screen in a liquid crystal display device. CONSTITUTION:In a case where the number of pixels in a horizontal direction is larger than that of video pixels in horizontal direction on one screen, a clock signal for speeding up a timing for each constant period is outputted as that for a data driver DD to fetch a video signal. For instance, when a display area in a horizontal direction is expanded by n/m times (m and n are integers and n>m) and 2L<-1n/m<=2<t> (t is a natural number), with a clock signal having a speed 2<t-1> times as fast as original as a base clock a clock signal actuated at a speed doubling the original at a rate of n-2<t-1>.m times in 2<t-1>.m times is outputted. In a case where the number of scanning lines in a vertical direction is larger than that of video scanning lines on one screen, enabling is applied to a scanning signal outputted from a gate driver DG to a scanning line LG and a nondriven scanning line is set for each specified number of scanning lines.

Abstract: PURPOSE:To obtain stable electrostatic charging potential by limiting a high voltage electric power source for electrostatic charging in such a way that the potential charged to a photoreceptor is made the same as that of the reference potential pattern formed on the non-image parts of the photoreceptor. CONSTITUTION:The potential of the reference pattern 10 formed on the non- image parts of a photoreceptor 1 is first measured with a surface electrometer probe 5 and a surface electrometer 6, and the voltage thereof is held with a sampling and holding circuit 6a. Thereafter, the photoreceptor 1 is charged with an electrostatic charger 8, and the surface potential of the charged photoreceptor 1 is measured with the probe 5 and the electrometer 6. This is compared with the above-described voltage in a differential amplifier circuit 6b. As a result, the output voltage X of the circuit 6b assumes + potential when the charged potential is high and - potential when low. If an arithmetic circuit 6c and a high voltage electric power source 7 for electrostatic charging are controlled in such a way that said output voltage X is made zero volts, the potential charged to the image part of the photoreceptor 1 is kept always equal to the reference potential pattern 10 formed in the non-image parts, and the stable image is obtained.
