Problems solved by technology

However, this prior art also has its disadvantages. If the positive and negative pixel voltages on adjacent data lines are asymmetrical with respect to the common electrode voltage (Vcom voltage), the neutralization potential during charge sharing will not reach the Vcom potential. V in the formula will not reach the minimum value
In addition, the existing technology integrates the charge sharing module into the driver chip, which increases the structural complexity of the driver chip

Abstract

The invention discloses an array substrate, a display panel and a polarity reversal driving method. The array substrate comprises a test line area and a display area, wherein the test line area comprises at least one reference voltage line; each data line in the display area is connected with the reference voltage line through a switch; a node is formed between the switch and the data line; the node is connected with a source driving circuit. Through adoption of an existing structure of the test line area on the array substrate, the data line of each pixel is communicated with the reference voltage line before the source driving circuit outputs gray-scale voltage, so that charge sharing between the pixels is realized, the fluctuation range of driving voltage is reduced, and thus the power consumption of the circuit is reduced.

Description

technical field [0001] The present invention relates to the technical field of display driving, in particular to an array substrate, a display panel including the array substrate, and a polarity inversion driving method based on the array substrate. Background technique [0002] 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 methods include frame inversion, row inversion, column inversion and dot inversion. Among them, the way of dot inversion can achieve the best picture effect, so it is widely used. [0003] In the source driver, for the same signal line, the driving voltage output on it is positive and negative ...
