Abstract

The invention discloses a method for patterning an adhesive barrier film, a display panel, and a display device, which are used to solve the problem that the prior art cannot guarantee the bonding that needs to be removed during the patterning process when the adhesive barrier film is patterned. The problem of complete separation of the type barrier film from the underlying substrate and without damaging other components of the underlying substrate. The patterning method of the adhesive barrier film includes: attaching the adhesive barrier film on the base substrate; according to the dividing track of the adhesive barrier film that needs to be retained and the adhesive barrier film that needs to be removed during patterning, the The adhesive barrier film is pre-cut; the adhesive barrier film to be removed is heated at a fixed point, so that the adhesion of the adhesive barrier film in this part is reduced; the adhesive barrier film at the fixed-point heating position is peeled off , to complete the graphics.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a patterning method of an adhesive barrier film, a display panel, and a display device. Background technique [0002] Flexible organic light emitting diode (Organic Light Emitting Diode, OLED) display panels are becoming a technical hotspot for next-generation display panels due to the rise of wearable display devices and their portability. One of the important technical difficulties of flexible OLEDs is how to ensure good packaging and airtight characteristics to block the intrusion of external water and oxygen. Usually, flexible OLEDs are encapsulated by multi-layer thin film deposition, that is, multiple layers of films that block water and oxygen are sequentially deposited on the OLED light-emitting device to protect the OLED device. Since the film deposition process is easy to cause the film layer to break due to foreign matter, it is necessary to attach a water and oxygen...
