Flexible circuit board and display panel

Abstract

The embodiment of the invention discloses a flexible circuit board and a display panel. The flexible circuit board comprises a main body part and an aided testing part connected with the main body part; multiple golden fingers are arranged on the main body part; each golden finger extends to a partition part at the connecting part of the main body part and the aided testing part; the partition part is used for separating the aided testing part from the flexible circuit board; each golden finger comprises at least a pair of testing bonding pads, one end of one testing bonding pad far away from the aided testing part is insulated from the one end of another testing bonding pad far away from the aided testing part; at least a pair of testing points are arranged on the aided testing part, and each testing point is electrically connected with the corresponding testing bonding pad. The flexible circuit board disclosed by the embodiment of the invention reduces the thickness of the display panel, and saves the internal space of the display panel; and the coupling impedance between the main flexible circuit board and the aided flexible circuit board or between the integrated circuit wafers can be precisely detected.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a flexible circuit board and a display panel. Background technique [0002] Usually, after the display device is manufactured, a series of testing procedures are performed to confirm whether the display quality of the display device meets the standard. Among them, the quality of bonding between the main flexible circuit board and the auxiliary flexible circuit board or integrated circuit chip is related to the quality of the entire process and affects the reliability of the product. Therefore, the detection of the bonding impedance is extremely important. [0003] At present, for the detection of the bonding impedance between the main flexible circuit board and the auxiliary flexible circuit board or integrated circuit chip in the display panel, an additional test pad or test board is provided in the display panel. However, these test pads or test boards are only...

Problems solved by technology

However, these test pads or test boards are only used for internal testing when the product is produced, and are useless after the product leaves the factory. However, the useless test pads or test boards still occupy the internal space of the product, which increases the thickness of the product. Meet the design requirements of thinner and lighter display devices
