Abstract:
A liquid crystal display device, including a display panel including data lines and gate lines intersecting the data lines, a gate driver configured to sequentially apply a scan signal to the gate lines, a data driver configured to apply data voltages corresponding to each gate lines to the data lines, a timing controller configured to control the gate driver and the data driver, a power source supply circuit configured to supply a positive power source and a negative power source, a common voltage feedback circuit configured to receive the positive power source and the negative power source from the power source supply circuit, receive a reference voltage and a common voltage from the display panel, and output an amplified feedback signal corresponding to a voltage level difference between the reference voltage and the common voltage.
