Abstract

The invention discloses an adhesive-type barrier film graphical treatment method, a display panel and a display device, so as to solve the problem that in the prior art complete separation of an adhesive-type barrier film which is to be removed in the graphical treatment process and a bottom substrate and no damage to other components of the bottom substrate cannot be guaranteed during graphical treatment of the adhesive-type barrier film. The adhesive-type barrier film graphical treatment method comprises: attaching an adhesive-type barrier film on a base substrate; precutting the adhesive-type barrier film, according to the trajectory of separation of the adhesive-type barrier film, which should be kept during graphical treatment, and the adhesive-type barrier film which should be removed during graphical treatment; carrying out fixed-point heating of the adhesive-type barrier film to be removed, so as to reduce the adhesion of the part of the adhesive-type barrier film; removing the adhesive-type barrier film at the fixed-point heating position, thereby completing the graphical treatment.

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...
