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.
Abstract:
The present invention relates to a method and apparatus for generating gray scale adjustment voltages and a panel driver circuit using the same. With the method provided in the invention, said apparatus for generating gray scale adjustment voltages generates a plurality of gray-scale reference voltage groups at a given time interval T0, and provides them for, such as a data driver circuit for adjusting gray scale of pictures by means of the reference gray-scale voltages, wherein values of the gray-scale reference voltages in each gray-scale reference voltage group are different from one another, and the time interval T0 need to be less or equal to a quotient from the displaying time in each frame divided by the product of the number of pixels in the vertical direction of a display screen and the number of gray-scale reference voltage groups. The present invention can improve the rate for outputting the gray scale voltages by said gray scale adjustment voltages generation apparatus without modifying the original data driver circuit in the liquid crystal display, such that a displaying effect of higher-order is obtained and improvement in picture quality is accomplished. The present invention may be widely used in various image display devices.
