Abstract

The invention discloses a driving system for an LCD. The driving system comprises a sequential control circuit (600) for storing data converted into gamma voltage and generating data converted into pixel gray-scale referential voltage, and a data drive circuit (500) which receives the data converted into gamma voltage and the data converted into pixel gray-scale referential voltage from the sequential control circuit (600), converts the data converted into gamma voltage and the data converted into pixel gray-scale referential voltage into gamma voltage and pixel gray-scale referential voltage respectively, and conducts gamma correction on the converted pixel gray-scale referential voltage through the converted gamma voltage to obtain the pixel gray-scale voltage. The invention further discloses a driving method for the LCD and the LCD. The LCD can conduct gamma correction while eliminating P-Gamma circuit, thereby substantially lowering the cost and sharpening the market competitive edge.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and in particular relates to a driving system and a driving method of a liquid crystal display, and a liquid crystal display. Background technique [0002] With the evolution of optoelectronics and semiconductor technology, it has also led to the vigorous development of flat panel displays (FlatPanelDisplay). Among many flat panel displays, liquid crystal displays (LiquidCrystalDisplay, LCD) have Electromagnetic interference and many other superior characteristics have been applied to all aspects of production and life. [0003] Existing LCD driving systems usually include a programmable gamma (P-Gamma) circuit. The P-Gamma circuit generates a Gamma voltage, and the Gamma voltage can be provided to the data driving circuit to perform gamma correction on the pixel gray-scale reference voltage generated by the data driving circuit to obtain the pixel gray-scale voltage. The pixel g...
