Abstract:
1. A liquid crystal display control circuit, comprising: an edge-detecting circuit for detecting image edges in a current frame of an image data, to divide data of the current frame into an edge data and a non-edge data; a memory coupled to the edge-detecting circuit, for saving an edge data of a previous frame of the image data without saving a non-edge data of the previous frame; a driving-decision circuit coupled to the edge-detecting circuit and the memory, for generating a driving voltage setting according to the non-edge data of the current frame outputted by the edge-detecting circuit, and generating an overdriving voltage setting according to the edge data of the previous frame and the edge data of the current frame outputted by the edge detecting circuit, and the driving-decision circuit comprises: an output device coupled to the driving decision circuit, for outputting the driving voltage setting and the overdriving voltage setting; wherein the output device is a multiplexer.
