DATA DRIVER CIRCUIT, LCD DEVICE AND DRIVING METHOD
Abstract:
The present disclosure provides a data driver circuit, a liquid crystal display (LCD) device, and a driving method. The data driver circuit for an LCD panel includes a source driver module, a pixel electrode, a common electrode opposite to the pixel electrode, and a gamma calibration module coupled to the source driver module. The source driver module is coupled to the pixel electrode. The data driver circuit further includes a compensation module. The compensation module detects and obtains a changed voltage of the common electrode voltage to generate a compensation voltage, and combines the compensation voltage and the gamma voltage of the gamma calibration module, then sends the combined voltage to the source driver module. The compensation voltage output by the compensation module and the changed voltage of the common electrode voltage can be mutually counteracted.
