Problems solved by technology

[0004] Among them, the narrowing design of the non-display area on the periphery of the display area, that is, the frame area, especially the lower frame area near the driver chip end, has always been an important research topic. The technical difficulty of narrowing the frame is getting higher and higher

Abstract

The embodiment of the invention provides a display panel, a test method for a display panel, and a display device. A partially multiplexed conventional test pad and a partially initialized test pad are used in a low frame region approaching a drive chip end in a non-display region of a display panel, so that the area, occupied by the partially initialized test pad, in the lower frame region is reduced. Therefore, the area of the lower frame area is reduced substantially and the jaw region of the display screen is narrowed down, so that the screen-to-body ratio of the whole display region is improved.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a display panel, a testing method for the display panel and a display device. 【Background technique】 [0002] As panel displays become more and more widely used, full-screen technology has become an important technical item. At the same time, the narrow bezel design of display panels is becoming more and more important in full-screen technology. Advanced electronic products, especially hand-held electronic products, tend to have a screen-to-body ratio of more than 90%. [0003] In order to increase the screen-to-body ratio of electronic products, the non-display area on the display panel is compressed smaller and smaller. For example, in the display screen of a mobile phone, in order to compress the non-display area as much as possible, an opening has been set at the top of the display area. A technology in which devices such as cameras and earpieces are placed in openings. ...
