Abstract

The invention discloses a dual-gate-line TFT (thin film transistor) array substrate and a display panel as well as a display device both comprising the same. Multiple transmission lines are adopted, each transmission line is arranged between two adjacent pixel columns and arranged between adjacent data lines, and the transmission lines and multiple gate lines are electrically connected correspondingly. Due to the designing mode of the transmission lines, frame area, occupied by peripheral line arranging, of the panel can be reduced, and typesetting rate can be increased.

Description

technical field [0001] The present invention relates to the field of Active Matrix Array, in particular to a Dual Gate Line TFT (Thin Film Transistor) array substrate, a display panel and a display device including the Dual Gate Line TFT array substrate. Background technique [0002] TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Transistor-Liquid Crystal Display) uses the change of the electric field intensity sandwiched on the liquid crystal layer to change the orientation of liquid crystal molecules, thereby controlling the intensity of light transmission to display images. Generally speaking, a complete liquid crystal display panel must have a backlight module, a polarizer, a TFT array substrate, a color filter (CF, Color Filter) substrate, and a liquid crystal molecule layer filled in a box composed of these two substrates. There are a large number of pixel electrodes on the TFT array substrate, and the on-off and magnitude of the voltage on the pixel e...
