Title: Driving method for liquid crystal panel
Inventor: HIROTSUNE SATOSHI
IPC: G09G3/36
Filed: 1989-11-20
Abstract: PURPOSE:To make exact gradation display by pulse width modulation by dividing a video display picture element selection period and determining a part thereof as the period to initialize the voltage of video display picture elements to a specified value. CONSTITUTION:The liquid crystal display picture element selection period is divided to two periods and the first period thereof is determined as the period to initialize the voltages of the liquid crystal display picture elements to the specified value, by which the charges of the liquid crystal display picture elements are first initialized at every frame period. The charges of the liquid crystal display picture elements are first initialized to the specified value at every one frame period in this case and, therefore, the desired charge quantity can be impressed to the liquid crystal display picture elements without receiving the influence of the charges previously accumulated in the liquid crystal display picture element. The exact gradation display is executed by the pulse width modulation in this way.

Abstract: PURPOSE:To enable highly-precise measurement of the amount of charge of toner even in an environment of high humidity by providing a heating means for preventing the lowering of resistance of the surface of a support of an electrode plate and by removing a waterdrop sticking on the surface of the support. CONSTITUTION:A developing roller 1 being rotated, a toner 5 charged with electricity is made to be attracted on a PET film 3 and development is conducted. Subsequently, this film 3 is separated from a drum 2 and the opposite surface thereof whereon the toner 5 is loaded is fitted closely on an electrode plate 8. An insulative support 10 supporting the electrode plate 8 has a support heating means 11 incorporated in the hollow-shaped inside so that a resistance conductor applies a voltage to the opposite ends thereof. A charge of the film 3 which has the charge of the same amplitude with that of the toner 5 through the electrode plate 8 is accumulated in a capacitor 6 after the toner 5 is separated from the film 3. When the heating means 11 is not operated in this constitution, the potential of the capacitor 6 lowers rapidly, while the initial potential is maintained without a leak of the charge when it is operated. Accordingly to this constitution, the amount of the charge of the toner can be measured with high precision.
