Abstract

The invention discloses a circuit board and a display device, and the circuit board comprises a substrate; a first detection contact which is arranged on the base body and is used for being electrically connected with a second detection contact of detection equipment; a first connection contact which is arranged on the base body and used for being electrically connected with a third detection contact of the display panel, wherein the first detection contact is correspondingly and electrically connected with the first connection contact. According to the scheme, due to the fact that the first detection contact and the first connection contact which are correspondingly and electrically connected are arranged, even after the circuit board is connected with the display panel, the display panel can be directly detected through the first detection contact, and therefore, the efficiency and accuracy of detection analysis are guaranteed; in addition, the assembly body of the circuit board and the display panel does not need to be disassembled through a Rework process, so that a series of problems such as no display caused by non-bright points and abnormal display caused by incapability of switching pictures due to adoption of the Rework process do not exist.

Description

technical field [0001] The present invention generally relates to the field of display technology, in particular to a circuit board and a display device. Background technique [0002] In the production process of the display device, multiple inspections are involved, such as inspection of the display panel, inspection of the driving circuit board, inspection of the assembly of the display panel and the driving circuit board, etc., to find out whether the product exists in time. question. [0003] At present, one of the assembly forms of the display panel and the driving circuit board is to bond the driving circuit board to the display panel. board, etc., causing the test contacts on the display panel to be covered, so that the display panel can no longer be directly tested (electrically tested). If it is found that there is a problem with the assembly of the display panel and the driver circuit board during the inspection, in order to determine whether it is a problem with...
