Liquid crystal panel and liquid crystal display with same

Abstract

The invention discloses a liquid crystal panel and a liquid crystal display with the same. The liquid crystal display panel comprises a plurality of pixels configured in an array. The array is formed by a plurality of data lines and a plurality scanning lines which are in orthogonal collocation. The scanning lines include at least two scanning lines corresponding to each line of pixels, each scanning line is connected to the line of pixels in a staggered manner, the scanning time of each line of pixels is divided into a plurality of time periods, when pixel drive signals are input to the pixels connected with one of the scanning lines through the data lines in each time period, the sum of the input signal change and pixel drive signal change of the data lines corresponding to the pixels connected with other scanning lines is 0, and the voltage of a common electrode is allowed not to deviate from preset voltage. By the arrangement, deviation, generated due to the fact that the common electrode is coupled by the data lines, of the voltage of the common electrode is weakened to a large extent, and horizontal crosstalk caused due to the fact that the voltage of the common electrode is coupled in the prior art is reduced.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a liquid crystal display panel and a liquid crystal display equipped with the same. Background technique [0002] In the field of thin film transistor-liquid crystal display (TFT-LCD), in order to overcome the DC blocking effect of the alignment film and enable the liquid crystal to be directional polarized, it is necessary to use a polarity inversion driving method to drive the liquid crystal, and the column inversion is more It saves power and has a better charging rate. Large-size panels often use this driving method. [0003] In the column inversion driving mode, the positive and negative polarities of the sub-pixels corresponding to the adjacent data lines are reversed in units of columns. This driving method makes there is a π phase difference between the flicker waveforms of two adjacent columns, which plays a role in suppressing flicker to a certain exten...

Problems solved by technology

Although this design can weaken the coupling effect of the data line to the common electrode to a certain extent, due to certain design requirements in this low color difference design and the influence of the feed through voltage, it will also be in the To a certain extent, the coupling effect of the data line to the common electrode is generated, so that the common electrode voltage Vcom deviates

Therefore, the 1G2D architecture still produces horizontal crosstalk caused by common electrodes being coupled
