Abstract: PURPOSE:To improve operability and to facilitate the handling of an electronic blackboard by electrifying and forming the latent image of original information inputted to the dielectric membrane of a blackboard sheet, attracting toner to the image and developing image by semi-fixing or fixing with heat. CONSTITUTION:An electrostatic head 4 has a writing-in electrode 4a and a control electrode 4b, electrifies the blackboard sheet 1 by means of the writing-in electrode 4a according to writing-in information from a control part 5 to form the latent image. The electrostatic head 4, a developing roll 8 constituting the developing means 6 and a fixing lamp 9 are arranged in a region where the blackboard sheet 1 at the bottom of a device is guided by a direction inverting guide 10 in order from the side of a lower roller 3. The development of the latent image is executed by the attraction of the toner attracted by the magnetism to the developing roll 8 and the toner is softened by the fixing lamp 9 to fix the toner. Thus operability is improved to facilitate the handling.

SOLUTION: In the active matrix system liquid crystal display device, which uses a time division driving method, while noticing that each shift register 31 of drivers IC 12-1 to 12-k has a function to act as a memory with a capacity equivalent to one line. Thus, R data among inputted display data, for example, are directly supplied to the driver IC 12-1 by bypassing a memory 36 by switching switches 37 and stored in each shift register 31 of the drivers IC 12-1 to 12-k.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device having a high video display quality and capable of suppressing the disturbance of video display caused when a video signal is interrupted and supplied again. SOLUTION: A master clock being the standard of a timing signal driving a liquid crystal display device is generated. As for the voltage to be impressed on a voltage controlled oscillator 3 in a master clock oscillator 20 whose phase is synchronized with the video signal, the voltage impressed on the voltage controlled oscillator 3 just before the impression is stored by the charge of a capacitor 10 and the stored voltage is impressed on the oscillator 3 when the video signal is interrupted by operations of switches 8 and 9. Thus, a previous oscillation frequency is maintained and the disturbance of video display at the time of supplying the video signal again is suppressed.

Abstract: PROBLEM TO BE SOLVED: To efficiently manufacture a liquid crystal display device capable of automatically outputting the liquid crystal driving signal matched with the driving mode of a liquid crystal display panel from a timing generator without changing the peripheral circuit of the generator and the program of a CPU. SOLUTION: This liquid crystal display device is constituted by the combination of a timing generator 1 and a liquid crystal display panel 2. The timing generator 1 has a circuit for judging that a liquid crystal driving signal is outputted at either mode of two modes, for example, by receiving a driving mode setting signal transmitted from the liquid crystal display panel 2. The panel 2 has either one of two driving modes of the generator 1 and outputs the driving mode and also displays a picture by the liquid crystal driving signal matched with the present driving mode from the generator 1.
