Abstract :
In this paper, new plus- and minus-voltage generators for TFT-LCD panels utilizing charge pump circuits are proposed. The plus- and minus-voltage generators can generate voltages with any amplitude by simply changing the number of stages of the charge pump circuit. It is demonstrated that the proposed generators can provide enough plus or minus bias-voltage for TFT-LCD panels by using the circuit analysis program HSPICE
