Protective film of conductive adhesive, circuit board and manufacturing method of display device

Abstract

The invention relates to the technical field of display, and discloses a protective film of a conductive adhesive, a manufacturing method of a circuit board and a display device. The protective film of the conductive adhesive comprises a photodetachable adhesive, such that the protective film is adhered to the circuit board through a photodetachable adhesive and a conductive adhesive, The adhesiveforce between the protective film and the circuit board is increased, and at least the peripheral area of the conductive adhesive is provided with a photodetachable adhesive, so that the protective film can be prevented from falling off from the conductive adhesive, the conductive adhesive is protected from being contaminated, and the conductive pattern and the static electricity releasing structure are reliably electrically connected through the conductive adhesive, thereby ensuring the static electricity derivation and improving the quality of the product. At that same time, when the display device is assemble, the photodetachable adhesive is irradiated with ultraviolet light, so that the photodetachable adhesive lose adhesion, the tearing force of the protective film is reduced, and the conductive adhesive is prevented from tearing off when the protective film is tear off, so that even if the adhesion between the protective film and the conductive adhesive is small, the protectivefilm 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.
