Abstract

The present invention provides an array substrate. By arranging a second metal layer into a grid structure, the grid structure and a constant voltage signal wiring disposed on a third metal layer areconnected in parallel, and a storage capacitor is used as a connection point of the grid structure, and the grid structure is used for reducing the voltage drop while ensuring the high-pixel density design so as to improve the uniformity of brightness. In the preparation process, the grid structure can be prepared in the manufacturing process of the second metal layer with no need for newly additional manufacturing processes so as to save the cost.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate. Background technique [0002] Organic light-emitting diodes (Organic Light-Emitting Diode, OLED) due to its light weight, self-illumination, wide viewing angle, low driving voltage, high luminous efficiency, low power consumption, fast response, etc., are widely used, especially in flexible display devices. With the characteristics of being bendable and easy to carry, it has become the main field of research and development in the field of display technology. [0003] At present, high-end mobile phones have high requirements on brightness uniformity. How to improve the brightness uniformity of the screen is the key direction of the development of major manufacturers. In the prior art, the Apple mobile phone adds a metal layer above the source and drain electrodes, and designs the VDD wiring (main power supply, powerline) in a grid pattern to reduce t...
