Array substrate, driving method thereof, display panel and display device

Abstract

The invention discloses an array substrate, a driving method thereof, a display panel and a display device. By the array substrate, power consumption on a source driving integrated circuit is reduced when point overturning is realized. All gate driving sub-circuits which are connected with odd-numbered rows of gate lines in the array substrate are connected to one another in a cascading manner to form a first gate driving circuit; all gate driving sub-circuits connected with even-numbered rows of gate lines are connected to one another in a cascading manner to form a second gate driving circuit; in a half displaying period displayed by a frame of an image, the odd-numbered rows of gate lines receive gate driving signals outputted by the first gate driving circuit, and the data lines receive first source driving signals outputted by the source driving integrated circuit; in the other half displaying period displayed by the frame of the image, the even-numbered rows of gate lines receive gate driving signals outputted by the second gate driving circuit, and the data lines receive second source driving signals outputted by the source driving integrated circuit; and the polarity of the first source driving signals is opposite to that of the second source driving signals.

Description

technical field [0001] The present invention relates to the technical field of displays, in particular to an array substrate and a driving method thereof, a display panel, and a display device. Background technique [0002] The prior art liquid crystal display (Liquid Crystal Display, LCD) includes an array substrate on which a plurality of thin film transistors (Thin Film Transistor, TFT) are distributed, and the drain of a TFT on the array substrate is connected to a pixel (pixel) electrode correspondingly, and the TFT The source of the TFT is correspondingly connected to a data (Data) line, and the gate of the TFT is correspondingly connected to a gate (Gate) line. The gate driver on array (GOA) technology is to integrate the thin film transistor as the gate switch circuit on the array substrate, thereby saving the gate driver integrated circuit part. In the array substrate, each row of Gate lines is correspondingly connected to a GOA circuit. Under the control of the ti...

Problems solved by technology

Since this structure needs to manufacture TFTs on both sides of a row of pixel electrodes, the manufacturing cost is relatively large and the process is relatively complicated in the actual manufacturing process.

[0005] For the double-gate structure, in order to reduce the power consumption of the source drive integrated circuit, that is, the positive and negative polarity of the signal input by the Data line does not change, adopt image 3 The pixel structure shown, when the Gate line is used figure 1 and figure 2 In the progressive scanning method, the polarities of two adjacent pixel units in the same row are the same, that is, the pixels in the dot flip realized in this case are flipped by two adjacent pixel points, which cannot be realized as figure 1 and figure 2 dot flip in

[0006] To sum up, in the prior art, when the signal input through the Data line is continuously switched between positive and negative polarities to achieve point inversion, it will cause excessive power consumption of the source driver integrated circuit, resulting in an increase in the temperature of the internal integrated circuit. ; When dot flipping is realized through the structure of the new array substrate, the production cost is higher and the process is more complicated
