A protective film of conductive adhesive, a circuit board and a manufacturing method of a display device

Abstract

The invention relates to the field of display technology, and discloses a protective film of conductive adhesive, a circuit board and a manufacturing method of a display device. The protective film of the conductive adhesive includes a photoreleasable adhesive, so that the protective film is pasted on the circuit board through the photoreleasable adhesive and the conductive adhesive, which increases the adhesion between the protective film and the circuit board, and at least the conductive adhesive The surrounding area has photo-releasable adhesive, which can prevent the protective film from falling off from the conductive adhesive and protect the conductive adhesive from contamination. The conductive pattern and the static discharge structure are electrically connected reliably through the conductive adhesive to ensure the export of static electricity and improve the safety of the product. quality. At the same time, when the display device is assembled, the photoreleasable adhesive is irradiated with ultraviolet light, so that the photoreleasable adhesive loses its viscosity, reduces the tearing force of the protective film, and prevents the conductive adhesive from being torn off when the protective film is torn off, so that even if the protection The viscosity between the film and the conductive adhesive is small, which can also ensure that the protective film is not easy to fall off.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a protective film of conductive adhesive, a circuit board and a manufacturing method of a display device. Background technique [0002] In order to reduce the influence of static electricity on the signal characteristics of the display module, exposed copper areas are often left on the flexible circuit board. The exposed copper area is in contact with a certain metal structure of the display module in order to quickly discharge static electricity. In order to stabilize the contact between the above two, it is necessary to use conductive adhesive to connect the two. Due to structural limitations, the area of ​​the exposed copper area is usually very small, and the area of ​​the conductive adhesive and the protective film is also small, so that the conductive adhesive protective film is easy to fall off, resulting in The conductive glue fails before connecting the two.
