Problems solved by technology

In the production process of the display screen, it is necessary to cut a large piece of glass substrate into several small pieces. Affected by the current cutting process, the edge of the small piece of glass substrate is very easy to produce tiny cracks. Although some small cracks can be removed through the edging process, but Deeper cracks cannot be removed, and the thickness of the glass substrate after the edging process is thinned, and new cracks are easy to add in the subsequent process. These cracks will expand to the inside of the display after the electronic product has been used for a period of time, damaging the circuit. , leading to abnormal display on the display screen, and at the same time, external water vapor, dust and other impurities are also easy to enter the display screen from the cracks, making the reliability of the display screen low

Abstract

The invention discloses a display panel and a display device. The display panel comprises a hollow part, a first non-display area, a display area and a second non-display area; the first non-display are is arranged around the hollow part, the display area is arranged around the first non-display area, and the second non-display area is arranged around the display area; the first non-display area comprises a conducting part and a crack detection line, the conducting part and the crack detection device are arranged at different layers, and vertical to a direction of a plane located by the display panel; the positive projection of the conducting part and the positive projection of the crack detection line are at least partially overlapped; the display area comprises at least one first conductor; and one end of the first conductor is electrically connected with the crack detection line. Compared with the prior art, the crack detection efficiency can be effectively improved, the signal linearrangement is simplified, and the display quality is ensured.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] In recent years, with the rapid development of mobile display technology, electronic products with display functions such as mobile phones, computers, and televisions have played an increasingly important role, and have gradually become necessities for people's life and work. Among these products, display The quality of the screen directly affects the quality of the picture display. [0003] Due to its unique high transparency, certain mechanical hardness and easy processing, the glass substrate has become one of the indispensable structures of the display screen. It is mainly used to protect the main light-emitting monomer of the display screen, the space required to form pixels, Support other structures of the display screen and so on. In the production process of the display screen, it is n...
