The invention provides a liquid crystal display device, which includes a source driver and a display panel, the display panel includes criss-cross data lines and scan lines, and a demultiplexing circuit connecting the source driver and the data lines, one of the source drivers The gate signal inputs n data signals to the demultiplexing circuit, and the demultiplexing circuit outputs n data signals to n data lines in the form of 1:n, and the demultiplexing circuit is equipped with The TFT switch and the clock signal for controlling the opening and closing of the TFT switch; within one scan time of the gate, the duration of the first n-1 data signals input to the demultiplexing circuit by the source driver is less than the duration of the last data signal. The liquid crystal display device of the present invention, aiming at the timing matching of the data signal input by the source driver (Soure IC) to the demultiplexing circuit and the corresponding CK / Gm, can significantly improve a certain path in the liquid crystal display device using the demultiplexing circuit technology. Or the problem of insufficient charging or uneven charging rate of several channels of pixels.
Description
technical field [0001] The invention relates to the technical field of liquid crystal panels, in particular to a liquid crystal display device. Background technique [0002] Demultiplexing circuit technology (DeMUX, hereinafter referred to as MUX) is being widely used in liquid crystal display panels, which can convert the strobe signal S output by the source driver (Source IC) to 1:n, such as 1:2, 1:3 etc. in the form of time-division transmission to the data line D of n columns of pixels. Taking 1:2 as an example, two sets of TFT switches are controlled by two clock signals CK1 and CK2, so that the strobe signal output by one source driver is output to the data line D of two columns of pixels in time division, so that the data output by the source driver The line can be reduced by at least half, and the number of source drivers can also be reduced, so the cost of the panel design can be reduced, and by saving the drawing space of the panel design, the width of the lower b...
