Abstract

The invention provides a back plate. The backboard comprises a substrate and pixel structures which are arranged on the substrate and are distributed in an array mode. The pixel structure comprises a power line, grid lines and data lines which are staggered in rows and columns, an anode of the back plate positioned on the substrate, a driving transistor electrically connected with the anode, and a switching transistor electrically connected with the driving transistor; the width direction of a channel in an active layer pattern of the driving transistor is the row direction, and the channel extends from a data line located on one side of the pixel structure to a power line located on the other side of the pixel structure in the row direction. According to the pixel structure provided by the invention, the area of the pixel structure can be reduced, and the width-to-length ratio of a TFT (Thin Film Transistor) is improved, so that the driving capability of a driving transistor is improved, and the resolution of a back plate is improved.

Description

technical field [0001] The present invention relates to the field of display technology or the field of 3D printing technology, in particular to a backplane. Background technique [0002] In the prior art, when making the backplane, when the size of the pixel area occupied by the pixel structure in the backplane is small, the driving transistors and switching transistors in the pixel structure cannot be rationally arranged, resulting in the inability to increase the aspect ratio of the driving transistors , the driving capability of the driving transistor cannot be improved. Contents of the invention [0003] The main purpose of the present invention is to provide a backplane to solve the problem in the prior art that the aspect ratio of the driving transistor cannot be increased when the size of the pixel area occupied by the pixel structure in the backplane is small when making the backplane. [0004] In order to achieve the above object, the present invention provides ...
