    摘要: An improved drive apparatus for a LC display screen is provided. The inventioned drive apparatus includes a programmable time setting means for changing drive currents in accordance with the size of the LC display screen. Depending upon the size of the LC display screen, it is necessary to change the drive current for charging up the display as promptly as possible at an initial stage of operation. The inventioned drive apparatus includes at least one time setting register means for programmably pre-setting a time according to the size of the display screen and a circuit selection means for providing a low resistor selection signal and a high resistor selection signal in accordance with the pre-set time of the time setting means.
