Array substrate, display panel and display device

Abstract

The invention discloses an array substrate, a display panel and a display device. The array substrate comprises a plurality of data lines arranged at a display area, a multi-path distributor assembly, a test switch assembly, and a plurality of data signal section routing units, wherein the multi-path distributor assembly, the test switch assembly, and the plurality of data signal section routing units are arranged at a non-display area. A signal output terminal of the multi-path distributor assembly is connected with the data lines and an input terminal of the multi-path distributor assembly is connected with output terminals of the data signal section routing units and the test switch assembly. The test switch assembly is arranged at one side, far away from the display area, of the multi-path distributor assembly. According to the invention, the plurality of data signal section routing units and the test switch assembly at the non-display area are changed to be arranged at different layers and thus overlapped areas are formed between the data signal section routing units and the test switch assembly, so that the existing continuous arrangement sequence of elements at the non-display area of the array substrate can be changed. Therefore, the width of the non-display area can be reduced under the circumstance that performances and dimensions of all elements at the original lower frame are kept; and thus the narrow frame effect can be realized while the process requirement is not enhanced and the production yield is not reduced.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] In order to improve the display effect of display devices, more and more people have begun to focus on the narrow frame design of display devices, especially for splicing screens used for large-screen outdoor displays. Narrow frame display devices can effectively reduce The width of the seam significantly improves the overall display effect. [0003] In the prior art, the narrow-frame display is usually manufactured by compressing the element size at the frame, which not only has a limited compression ratio, but also increases process requirements and reduces production yield. At the same time, product performance is also affected to a certain extent. [0004] Therefore, how to compress the width of the lower bezel to achieve the effect of a narrow bezel while maintaining the original perform...
