A circuit board, a display module, and a display device are provided. The circuit board includes: a base substrate including a first surface and a second surface opposite to each other; bonding pads on the first surface; test pads electrically connected to the bonding pads and disposed on the second surface; a test auxiliary structure on the second surface; and a metal layer on the second surface. The test auxiliary structure overlaps with the test pads along a first direction which is a direction perpendicular to the first surface and the second surface of the base substrate; and the metal layer includes a metal structure for transmitting a first signal and the test auxiliary structure is insulated from the metal structure.

Circuit board, display module, and display device

The present disclosure relates to the field of circuit testing technologies and discloses a flexible circuit board and a test fixture. The flexible circuit board comprises: a flexible body which has a first crimping portion and an extension portion, the first crimping portion being used to be laminated with a second crimping portion of a substrate to be tested; a first electrically connected structure which is located on a first side of the flexible body, arranged on the first crimping portion, and used to be laminated with a second electrically connected structure on the second crimping portion; a support structure which is located on the first side of the flexible body and includes a first support portion and a second support portion; the first support portion is arranged on the extension portion and configured to support the extension portion in the laminating state.

Flexible circuit board and test fixture

The present disclosure provides a flexible circuit board. The flexible circuit board includes a substrate; a conductive layer, disposed on the substrate; and a cover layer, disposed on a side of the conductive layer facing away from the substrate. The flexible circuit board is provided with a through hole penetrating through the flexible circuit board in the thickness direction. The cover layer includes a hollowed-out region located at least at an edge of one side of the through hole. The conductive layer includes an electrostatic discharge section exposed in the hollowed-out region.
