Abstract:
1. An amplifying circuit for a liquid crystal display including a plurality of pixels, the amplifying unit comprising: an input unit, coupled between a first power source for supplying a first voltage and a second power source for supplying a second voltage, receiving a first input signal and a second input signal, and being controllable by the first and second input signals; a bias unit receiving a bias voltage for operating the input unit, and including a first node and a second node controlled by the input unit; and an output unit for applying an output voltage to a selected pixel by using a first output transistor being turned on/off according to a signal applied to the first node and a second output transistor being turned on/off according to a signal applied to the second node, the second output transistor being different from the first output transistor, wherein the input unit includes: wherein the bias unit includes: wherein the output voltage is applied to the input unit, such that one of the first and second input signals is equivalent to the output voltage.
