Abstract

The invention discloses a display panel and a cutting panel, and relates to the technical field of display. The display panel comprises a non-display area, the non-display area comprises at least one crack detection circuit, the crack detection circuit comprises a crack detection signal line, a crack detection unit and at least one built-in electrostatic protection element, and the built-in electrostatic protection element is electrically connected with the crack detection signal line; the built-in electrostatic protection element comprises an electrostatic protection capacitor module; the crack detection unit is arranged in a first sub-non-display area, and at least part of the electrostatic protection capacitor module is arranged in a second sub-non-display area and/or a third sub-non-display area. The first sub non-display area and the second sub non-display area are oppositely arranged. According to the invention, the plurality of electrostatic protection capacitor modules are arranged outside the first sub-non-display area, so that a component for releasing static electricity is prevented from being arranged in the first sub-non-display area with a smaller space, and the crack detection signal line is electrically connected with more electrostatic protection capacitor modules, thereby being beneficial to improving the electrostatic discharge capacity of the crack detection signal line.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel and a cutting panel. Background technique [0002] In the prior art, due to the design of the display panel, structural components such as driver chips and drive circuits are often installed in the lower frame area, but at present, components for discharging static electricity are still placed in the lower frame area. Before the line enters the crack detection unit, the components used to discharge static electricity will be concentrated in the lower frame area, and a sufficient number of electrostatic discharge components cannot be placed to make the crack detection signal line exist. The static electricity is sufficiently dissipated, so there is no guarantee that the problem of electrostatic breakdown of the crack detection unit can be avoided. Therefore, it is urgent to provide a display panel that can be provided with more electrostatic disc...
