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 inversion driving method. The array substrate includes a test line area and a display area, the test line area includes at least one reference voltage line, each data line in the display area is connected to the reference voltage line through a switch, and the switch A node is formed between the data line and the node is used for connecting with the source driving circuit. The present invention utilizes the existing structure of the test line area on the array substrate, and before the source drive circuit outputs the gray scale voltage, the data line of each pixel is connected to the reference voltage line to realize the charge sharing among the pixels, so that the driving voltage The swing range is reduced, which reduces the power consumption of the circuit.

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 ...
