The display panel includes: a first special-shaped display area, a first non-display area and a second special-shaped display area, the first non-display area is located between the first special-shaped display area and the second special-shaped display area; the normal display area and the second non-display area Areas, the first non-display area, the normal display area and the second non-display area are arranged along the second direction; the test circuit located in the second non-display area; the test circuit includes a first data bus, and the first data bus is electrically connected to the A plurality of first data lines in different-shaped areas; the test circuit also includes a second data bus, which is electrically connected to the plurality of second data lines in different-shaped areas through transistors; the first data bus and the second data bus are disconnected.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a display device and a testing method. Background technique [0002] At present, the design of electronic devices such as mobile phones and tablet computers is developing towards a high screen-to-body ratio. The screen-to-body ratio is used to represent the relative ratio between the screen and the front panel area of ​​the electronic device. Problems to be solved by people. In order to increase the screen-to-body ratio and realize functions such as front cameras at the same time, a special-shaped display panel has appeared. The special-shaped display panel includes a non-display area embedded in the edge or inside of the display area, and the non-display area is at least partially surrounded by the display area. The non-display area is provided with an optical device such as a front camera to realize the front camera function, and at the same time, s...
