ABSTRACT:
In a liquid crystal driving circuit according to the present invention, a variable resistor is provided between each of power lines and an output terminal to control the driving ability of this circuit. The resistivity of this resistor can be changed in analog or in digital. In the digital case, the variable resistor can be formed with a constant resistor and a by-pass switch. In order to increase the variable stages of the liquid crystal driving ability of the circuit, a plurality of combinations, each of which is comprised of said constant resistor and said by-pass switch, are provided between each of power lines and the output terminal.
