Wuhan Tianma Micro-Electronics Co., Ltd

Chunming Jin

A display panel and a display device are provided. In an embodiment, the display panel includes a substrate; an isolating pillar; and a light-emitting functional layer. In an embodiment, the display panel has a display region, a first non-display region and a through-hole region. In an embodiment, the isolating pillar includes at least one isolating group, each of which includes a first sub-portion, and a second sub-portion. In an embodiment, the first sub-portion includes a middle portion and two end portions. In an embodiment, a cushion layer structure is disposed between the end portion and the second sub-portion, and an edge of the end portions extends beyond the cushion layer structure in the first direction to form a respective step.

Display panel and display device

A display panel, a detection method of a display panel, and a display device are provided. The display panel includes a display region and a non-display region surrounding the display region. The display region includes a plurality of sub-pixels and at least one first detection line. At least one sub-pixel of the plurality of sub-pixels includes at least one to-be-tested device, and the at least one to-be-tested device is electrically connected to the at least one first detection line. The non-display region includes at least one detection pad, and a detection pad of the at least one detection pad is electrically connected to a first detection line of the at least one first detection line.

Display panel, detection method and display device

A display panel, an electronic device and a crack detection method are provided. The display panel includes: a substrate and a detection signal line located on a side of the substrate, where the detection signal line is located in the non-display area, and includes a first detection signal line and a second detection signal line arranged in sequence in a first direction, and when detecting cracks, the first detection signal line and the second detection signal line may be used to detect cracks in different manners or in the same manner, to improve the reliability of crack detection. In addition, one of the first detection signal line and the second detection signal line may be selected for crack detection according to the actual situation, to improve the efficiency of crack detection.
