Problems solved by technology

However, the reaction of ammonia, silane and nitrogen needs to be carried out in a low temperature environment, and a large amount of ammonium ions will be generated; after the thin film encapsulation layer is formed, some ammonium ions will remain in the thin film encapsulation layer
[0004] When the packaged display panel is in a high temperature and high humidity state or an environmental state, the ammonium ions remaining in the thin film encapsulation layer will overflow in the form of ammonia gas and react with the dyed substance in the polarizer of the display screen. Cause the polarizer to fade and affect the display effect of the entire display

Abstract

The invention provides a display panel packaging method, a display panel and a terminal. The method comprises the following steps: forming a thin film packaging layer on a display panel to obtain a packaged display panel; spraying acid gas to the packaged display panel, completing aftertreatment of the packaged display panel, and using the acid gas for absorbing ammonia gas diffused out of the thin film packaging layer. Therefore, the risk that the ammonia gas diffused from the thin film packaging layer reacts with the dyeing substance of the polaroid of the display screen is reduced, the riskthat the polaroid fades is further reduced, and the display effect of the display screen is improved.

Description

Technical field[0001]The embodiments of the present disclosure relate to the technical field of terminal preparation, and in particular, to a packaging method of a display panel, a display panel, and a terminal.Background technique[0002]A flexible OLED (Organic Light-Emitting Diode) display panel includes a base substrate, and OLED devices (including anode, cathode, light-emitting devices, etc.) arranged on the base substrate. Due to the flexibility of the flexible OLED display panel, the traditional rigid cover cannot be used for packaging, and thin film packaging technology is introduced.[0003]The thin-film packaging technology is to form a thin-film packaging layer covering the OLED device on a substrate to prevent the OLED device from being damaged by moisture and oxygen. The process of forming a thin film encapsulation layer includes: using ammonia gas (NH3), silane (SiH4) And nitrogen (N2) And other mixed gases are used as reaction gases to deposit on the substrate to form sil...
