Problems solved by technology

, however, the charging rate of the pixel cell whose polarity is reversed during charging is low, and the charging rate of the pixel cell that is not polarized during charging is high
The difference in charging rate will cause dark lines and bright lines on the display panel, which will reduce the display effect and affect the user experience

Abstract

The invention discloses a liquid crystal display panel and a gate drive circuit. The liquid crystal display panel includes: a plurality of pixel units arranged in a matrix; a plurality of scan lines, each two of the scan lines corresponding to the same row of pixel units and alternately connected to the pixel units in the same row of pixel units; a gate driving circuit a plurality of data lines, each of which is respectively connected with two adjacent columns of pixel units; a data drive circuit; wherein, the gate drive signals on the two scan lines corresponding to the same row of pixel units have different drive capabilities. In the above manner, the present invention can reduce the brightness difference on the display panel and improve the display effect.

Description

technical field [0001] The invention relates to the field of display panels, in particular to a liquid crystal display panel and a grid driving circuit. Background technique [0002] Liquid crystal display panels are widely used in various electronic products due to their high display quality, low price, and easy portability. With the continuous development of liquid crystal display technology, new driving methods are needed to cope with the gradually decreasing panel costs. The number of signals, and the gate side uses GOA (Gate driver on Array) technology to achieve. In a liquid crystal display panel, if the liquid crystal molecules are always driven with a positive or negative voltage, it is easy to cause damage to the liquid crystal molecules. Therefore, in order to protect the liquid crystal molecules from being damaged by the driving voltage, the liquid crystal molecules must be driven by alternating positive and negative voltages. Currently common polarity inversion...
