Array substrate and display driving method thereof and display device

Abstract

The invention provides an array substrate and a display driving method thereof and a display device. The array substrate comprises a common voltage wire, multiple pixel electrodes arranged in rows and lines and at least one first transistor arranged between two adjacent pixel electrodes. The grids of the first transistors are connected with the common voltage wire, and the first pole and the second pole of each first transistor are connected with the two corresponding adjacent pixel electrodes respectively. In addition, the display driving method of the array substrate includes the steps that voltage is applied to the common voltage wire between adjacent display frames, and all the first transistors with the grids connected with the common voltage wire work in a linear region or a saturation region. On the basis, polarity neutralization of gray-scale voltage between adjacent pixels can be achieved on the premise that the aperture ratio of the pixels is not lowered, power consumption is greatly reduced on the premise that the display effect is not affected, and the minimum power consumption of an existing display device is broken through.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display driving method thereof, and a display device. Background technique [0002] In a specific type of polarity inversion working mode, the polarities of the grayscale voltages of adjacent pixels in a liquid crystal display (Liquid Crystal Display, LCD) at the same time may be reversed. Based on this, the prior art proposes a technical solution of neutralizing positive and negative voltages on adjacent data lines before a frame is started to reduce power consumption. However, in practice, the parasitic capacitance of the data line is small in value, and the power consumption thereof is negligible compared with the power consumption consumed by charging and discharging the capacitance inside the pixel. Therefore, it is obviously more effective for reducing power consumption if the polarity neutralization of gray scale voltages between adjacent pi...

AI Technical Summary

Problems solved by technology

The main reason is that the polarity neutralization of the gray-scale voltage between adjacent pixels often requires an additional control signal line to control the timing of the polarity neutralization of the gray-scale voltage, and this additional control signal line The setting of will inevitably occupy part of the area of ​​the pixel opening, resulting in a serious loss in the pixel opening ratio
