Abstract

The embodiment of the invention provides a driving method of a DEMUX liquid crystal display panel. The method comprises the steps that when a kth clock signal is triggered, the status of the kth set of DEMUX switching tubes is obtained, and the status of the (k+1)th set of DEMUX switching tubes is obtained, wherein 1<=k<m; if the kth set of DEMUX switching tubes is turned on and the (k+1)th set of DEMUX switching tubes is turned off, and when (k+1) clock signals are triggered, the (k+1)th set of DEMUX switching tubes are driven to be turned on. In addition, the embodiment of the invention further provides the DEMUX liquid crystal display panel. The diving method of the DEMUX liquid crystal display panel can reduce system resources needed when DEMUX drive signals are generated, and reduce the influence of signal delay on a DEMUX switching circuit.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a DEMUX liquid crystal display panel and a driving method thereof. Background technique [0002] At present, in the design process of the liquid crystal display panel, in order to reduce the number of output channels of the driving chip, a DEMUX switching circuit is added to the driving circuit of the liquid crystal display panel, thereby reducing the output channels of the driving chip by multiples. With the improvement of the integration of liquid crystal display panels and the development of cost control, a 1 to 6 DEMUX liquid crystal display panel has been proposed, such as figure 1 shown. The DEMUX liquid crystal display panel can provide the data voltage output by one channel to the corresponding six data lines in time division. However, the DEMUX liquid crystal display panel requires the driver chip to generate 6 DEMUX driving signals during each scan line, such as ...
