Abstract

Provided is a display panel. The display panel includes a driver circuit, at least one to-be-detected line, and at least one conductive line in one-to-one correspondence with the at least one to-be-detected line. Any to-be-detected line in the at least one to-be-detected line includes a first sub-line and a second sub-line arranged separating from each other, and another end of the second sub-line is exposed out of an edge of the display panel. The second sub-line is configured to be electrically connected to a detection unit outside the display panel prior to cutting of a display panel motherboard including the display panel.

Dependent claims

A display panel, comprising a driver circuit, at least one to-be-detected line, and at least one conductive line in one-to-one correspondence with the at least one to-be-detected line;

wherein
each of the at least one to-be comprises a first sub-line and a second sub-line arranged separating from each other, wherein the first sub-line is electrically connected to the driver circuit and a conductive line corresponding to the to-be-detected line respectively, one end of the second sub-line is electrically connected to the conductive line corresponding to the to-be-detected line, and another end of the second sub-line is exposed out of an edge of the display panel;
and
wherein the second sub-line is configured to be electrically connected to a detection unit outside the display panel prior to cutting of a display panel motherboard comprising the display panel.

1 more element

A display panel motherboard, comprising at least one display panel and a to-be-cut plate disposed outside the display panel;

wherein
the display panel comprises a driver circuit, at least one to-be-detected line, and at least one conductive line in one-to-one correspondence with the at least one to-be-detected line;
each of the at least one to-be-detected line comprises a first sub-line and a second sub-line arranged separating from each other, wherein the first sub-line is electrically connected to the driver circuit and a conductive line corresponding to the to-be-detected line respectively, and one end of the second sub-line is electrically connected to the conductive line corresponding to the to-be-detected line;
and
the to-be-cut plate is provided with a detection unit and at least one detection line electrically connected to the detection unit, wherein the at least one detection line is in one-to-one correspondence with the at least one to-be-detected line, and another end of the second sub-line is electrically connected to a detection line corresponding to the to-be-detected line.
