The invention provides a driving circuit and a liquid crystal display panel. The driving circuit comprises the components of a plurality of data signal sources; m control signal sources; and a plurality of switch modules, wherein each switch module comprises an input end, m control ends and n output ends. The input end is connected with a corresponding data signal source; the control ends are connected with the corresponding control signal sources; and the output ends are connected with corresponding subpixels. Each control signal source is connected with n output ends, wherein m is an integer which is larger than 0, n is larger than m and furthermore n is smaller than 2^m-1. According to the driving circuit and the liquid crystal display panel, through connecting each control signal source with all subpixels and making all subpixels perform charging by one control signaal source, the number of control signals is reduced. Furthermore an adverse influence on thickness and cost of the liquid crystal display panel is prevented.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a driving circuit and a liquid crystal display panel. Background technique [0002] With the development of liquid crystal display panels, people have higher and higher requirements for liquid crystal display panels, such as resolution, thinness and cost. However, the pursuit of high-resolution liquid crystal display panels requires more and more data lines, which adversely affects the thinness and cost of the panels. In the prior art, in order to reduce the number of data lines, one data line is used to correspond to multiple sub-pixels, and the control signals provided by multiple control signal sources are used to charge the sub-pixels connected to the data line one by one, thereby saving corresponding A certain cost, and it is helpful to the thinning of the panel. [0003] However, using the above method to charge the sub-pixels increases the number of contro...
