Array substrate and micro total analysis device

Abstract

The invention discloses an array substrate and a micro total analysis device. The array substrate includes a substrate, a plurality of pixel regions which are arranged on the substrate and limited bycrossing of a data line and a grid line, and driving transistors in the pixel regions, wherein each driving transistor includes an active layer graph, and a first preset angle is displayed between theextending direction of the active layer graph and the grid line, and the active layer graph strides the pixel region in an inclined manner in the first preset angle direction; and the source and drain electrodes of each driving transistor are connected to the active layer graph in the first preset angle direction. By setting the first preset angle between the extending direction of active layer graph and the grid line, compared with a conventional device which sets the extending direction of the active layer to be parallel with the grid line, the array substrate can increase the length of theactive layer graph in the extending direction, thus increasing the length breadth ratio of the active layer graph while not increasing the area of the occupied pixel area, so as to improve the conductivity of the driving transistors while realizing high pixel design.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to an array substrate and a micro-total analysis device. Background technique [0002] The conduction capability of the transistors on the array substrate directly affects the accuracy of data transmission. Especially as the driving voltage increases, the stability of the transistor will be greatly affected. That is, as the voltage increases, the threshold voltage and characteristics of the transistor will become poor, thereby affecting the conduction characteristics of the transistor. [0003] In related technologies, by increasing the aspect ratio of the active layer pattern of the transistor, the stability of the transistor can be improved, and the conduction characteristics of the transistor can also be guaranteed to be unaffected when the driving voltage is increased, but increasing the active layer of the transistor The aspect ratio of the graphics will occupy a larger are...
