Abstract

The invention provides an array substrate. The array substrate comprises a display region and a binding region, wherein the binding region is arranged at one end of the display region and comprises signal conversion lines and connection terminals, the signal conversion lines and the connection terminals are correspondingly connected, the signal conversion lines extend along a first direction and are connected with two connection terminals adjacent to the signal conversion line, the projections of the signal conversion lines on a reference surface along a second direction are not coincided, thus, the distance between adjacent connection terminals can be expanded by design that adjacent connection terminals are arranged in a staggered way, and the problems that the distance between the connection terminals of an existing array substrate is excessively small and short circuit is easily generated during binding to cause unfavorable binding are solved.

Description

technical field [0001] The present invention relates to the display field, in particular to an array substrate. Background technique [0002] Formed with drive circuits, such as TFT circuit array substrate (also known as TFT substrate), is an integral part of the display device, which includes a display area, a binding area arranged at one end of the display area, including a signal conversion area and connection terminals The signal conversion area is provided with signal conversion lines, and the connection terminal area is provided with connection terminals. The signal conversion lines are correspondingly connected to the connection terminals, and the binding between the array substrate and the driver chip is realized based on the connection terminals. [0003] Among them, the design of the signal conversion lines and connection terminals in the binding area will directly affect the yield rate of the binding. The higher the resolution of the product, the denser the connec...
