Display module driving circuit, driving method and liquid crystal television

Abstract

The embodiment of the invention provides a display module driving circuit, a liquid crystal television and a display module driving method, relates to the field of electronic technology, and solves the technical problem in the prior art that a video processing chip is debugged with a heavy workload. The display module driving circuit comprises a data processing module, a GAMMA voltage generating module and a driving module, wherein the data processing module is used for processing an image displaying signal into a line synchronization signal, a field synchronization signal, a data driving signal and a scanning driving signal; the GAMMA voltage generating module is used for transmitting a GAMMA voltage corresponding to the GAMMA voltage value which is corrected according to a preset GAMMA curve to the driving module after receiving the line synchronization signal; and the driving module is used for generating a driving voltage by using the GAMMA voltage as the reference voltage according to the line synchronization signal, the field synchronization signal, the data driving signal and the scanning driving signal, and loading the driving voltage on pixels on a liquid crystal display module and corresponding to the line synchronization signal, the field synchronization signal and the scanning driving signal. The display module driving circuit, the liquid crystal television and the display module driving method are applied to improvement of the display effect of the liquid crystal television.
