摘要： An apparatus and method for generating bias voltages for an LCD driver. A voltage divider including serially connected resistors of a first resistance is arranged to form a DC current path having nodes. The voltage of each node serves as a bias voltage to the LCD driver for actuating the LCD driver to generate LCD driving signals. A signal generator is used to generate a switching signal in synchronism with the LCD driving signals. A switching circuit including switches is arranged so that when the switches are closed, the resistance between two adjacent nodes has a small value, so as to provide large driving currents to the LCD driver, and when the switches are open, the resistance has a large value, so as to reduce the amount of leakage current through the DC current path.

摘要： An apparatus and method is provided for generating a set of bias voltages for a liquid crystal display (LCD) driver to drive an LCD panel. This apparatus and method are directed to solving the problems of excessive use of I/O pads and power consumption in conventional LCD drivers and also the problems of the non-matching between externally connected resistors and the internal resistance in conventional LCD drivers. Further, externally connected capacitors for increasing bias current in conventional LCD drivers are not needed. The apparatus and method is capable of switching a bias current to a top level which causes a voltage divider to provide adequate bias voltages to the LCD driver at each instant when the LCD waveforms are being switched from one state to another, and to a bottom level when the LCD waveforms are at steady states so as to reduce power consumption to save energy.
