LCD DRIVER |
摘要 |
PURPOSE: A liquid crystal display driver is provided to assign the common reference voltage to each channel by identically distributing a digital input code in MSB and LBS by using DAC decoder. CONSTITUTION: A first DAC circuit(402) comprises a plurality of first input nodes connected to each output terminal of the first DAC. The first DAC circuit outputs the first output signal having the first voltage level is outputted. The second DAC circuit(404) comprises a plurality of second input shifts connected to each output terminal of the second DAC. The second DAC circuit outputs the second output signal having the second voltage level corresponding to a voltage level. A buffer(406) receives an output signal from the first DAC circuit and the second DAC circuit.
