ABSTRACT:
A common voltage adjusting circuit (200) includes a delta adder (21), a sigma adder (22), a sigma latch (23), and a quantization circuit (24). The delta adder includes a first input terminal configured for receiving a binary signal, a second input terminal, and an output terminal. The sigma adder includes a first input terminal connected to the output terminal of the delta adder, a second input terminal, and an output terminal. The sigma latch includes a first input terminal connected to the output terminal of the sigma adder, and an output terminal connected to the second input terminal of the delta adder and the second input terminal of the sigma adder. The quantization circuit includes a first input terminal connected to the output of the sigma latch, and an output terminal connected to a common electrode of a TFT-LCD.
