Problems solved by technology

Because the common voltage generator 15 produces a fixed common voltage, the highest voltage of the pixel electrode 17 needs to reach more than twice the voltage of the common electrode 18, and the voltage of the pixel electrode 17 is provided from the data driver 14, so the data driver 14 provides The operating voltage range is more than twice that of the public voltage. This method undoubtedly requires a high voltage range for the data driver 14, and the complexity of the manufacturing process and the circuit is relatively increased, and the cost will also be increased accordingly.

Abstract

The invention provides a liquid crystal display device. In the liquid crystal display device, a first public voltage and a second public voltage which are constantly changed are used, public electrodes of different pixel units at the same row are respectively connected with the first public voltage and the second public voltage, thus a data driver dose not need to provide twice public voltage, thereby relatively reducing the production process and circuit complexity of the driving circuit of the liquid crystal display device so as to reduce cost.

Description

technical field [0001] The invention relates to a liquid crystal display device. Background technique [0002] Liquid crystal displays are widely used because of their low radiation, light, thin and small size, and low power consumption. With the maturity and innovation of related technologies, there are more and more types. [0003] see figure 1 , the liquid crystal display 10 in the prior art includes a liquid crystal panel 11 , a timing controller 12 , a scan driver 13 , a data driver 14 and a common voltage generator 15 . The scan driver 13 and the data driver 14 are used to drive the liquid crystal panel 11 , the timing controller 12 is used to drive the scan driver 13 and the data driver 14 , and the common voltage generator 15 is used to provide a common voltage for the liquid crystal panel 11 . [0004] The liquid crystal panel 11 includes a plurality of parallel scan lines 131, a plurality of parallel and intersecting data lines 141 perpendicular to the scan lines...
