Display panel, array substrate and manufacturing method thereof

Abstract

A display panel, an array substrate and a manufacturing method therefor. The array substrate comprises a plurality of pixel units; each pixel unit comprises a gate line (11) and a common line (12), wherein the gate line (11) comprises a first segment of line (11a) and a second segment of line (11b) which are arranged to be disconnected; an electrical connection structure is arranged at a disconnection opening of the first segment of line (11a) and the second segment of line (11b); the first segment of line (11a) and the second segment of line (11b) are electrically connected via the electrical connection structure; and the common line (12) passes through the disconnection opening in a direction perpendicular to the gate line (11), and is in insulated contact with the first segment of line (11a) and the second segment of line (11b) respectively. The uniformity of an optimum common voltage can be increased, thereby improving the quality of products.

Description

Technical field [0001] The present invention relates to the field of liquid crystal display technology, in particular to a display panel, an array substrate and a manufacturing method thereof. Background technique [0002] With the development of the information society, people's demand for display devices has increased, which has also promoted the rapid development of the LCD panel industry. As the output of liquid crystal display panels continues to increase, people have higher requirements for product quality and yield. Therefore, improving product quality, reducing defect rates, and saving costs have become major issues in this field. [0003] At present, in the design of the array substrate, the common line is usually arranged in the same layer as the gate line and parallel to the gate line, and all the common lines are shorted together outside the effective display area. During display, the peripheral circuit applies a common voltage from one or both ends of the common line....

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventors of the present invention have found that the prior art has at least the following technical defects: in the above-mentioned design, due to the continuous increase of the size of the TFT-LCD, the length of the common line is also getting longer and longer. Therefore, the voltage drop of the common line leads to inconsistent optimal common voltages at different positions on the common line. For example, the common voltage at the end of the common line is greater than the common voltage at the middle of the common line, which makes the uniformity of the common voltage poor, and image retention is prone to occur ( ImageSticking) phenomenon
