Low-frequency low-power-consumption array substrate and manufacturing method thereof

Abstract

The invention discloses a low-frequency low-power-consumption array substrate which comprises a pixel area; the pixel area comprises a first electrode layer, a first insulating layer, a second electrode layer, a second insulating layer and a third electrode layer which are stacked up and down, the first electrode layer comprises a first electrode, and the second electrode layer comprises a secondelectrode; the third electrode layer comprises a third electrode; the first electrode and the second electrode are at least partially overlapped up and down, so that a first storage capacitor is formed by the upper and lower overlapped parts of the first electrode and the second electrode; and the second electrode and the third electrode are at least partially overlapped up and down, so that a second storage capacitor is formed by the upper and lower overlapped parts of the second electrode and the third electrode. According to the low-frequency low-power-consumption array substrate, the voltage maintaining time of the pixel electrode can be prolonged under the condition that the resolution is not reduced, so that the pixel electrode still has sufficient voltage maintaining time in a low-frequency and low-power-consumption working state. The invention further discloses a manufacturing method of the low-frequency low-power-consumption array substrate.

Description

technical field [0001] The invention relates to display technology, in particular to a low-frequency and low-power consumption array substrate and a manufacturing method thereof. Background technique [0002] With the development of the panel display industry, the resolution requirements of the liquid crystal panel are getting higher and higher, and the power consumption of the liquid crystal panel is also increasing accordingly. In order to reduce power consumption without lowering the resolution, it is often used to reduce the refresh frequency of the liquid crystal panel to achieve the purpose of reducing power consumption. [0003] In the prior art, a common electrode layer VCOM is provided on the TFT substrate of the liquid crystal panel, and the common electrode in the common electrode layer VCOM will insulate and overlap with the pixel electrodes to form a storage capacitor. The liquid crystal panel relies on the The storage capacitor is used so that the pixel electr...

AI Technical Summary

Problems solved by technology

After the refresh frequency is reduced, in order not to affect the display effect of the liquid crystal panel, the voltage sustaining time of the pixel electrode needs to be increased, that is to say, the area of ​​the storage capacitor needs to be increased to store more charge each time, but the The increase in the area of ​​the storage capacitor will occupy the space of the pixel electrode, so that the pixel density will be reduced, and the resolution of the liquid crystal panel will be reduced.
