Problems solved by technology

OLED and QLED display devices mostly use thin-film packaging, but to achieve a good water and oxygen barrier effect, it takes a long time to prepare thin films using thin-film packaging, and as the number of packaging layers increases, the time will be longer. This method not only consumes time, but also consumes energy

Embodiment 1

[0043] A flexible device packaging method, comprising the following steps:

[0044] (1) Attachment of drying sheet

[0045] Clean the 3cm×2cm tinfoil paper (metal sheet) ultrasonically for 10 minutes with acetone, absolute ethanol and deionized water respectively, put the cleaned tinfoil paper into a glove box containing high-purity nitrogen, and use a heating platform for no more than Dry the metal sheet at a temperature of 60°C, and then stop heating. When the metal sheet dissipates the heat of drying and the water and oxygen content of the glove box is within the normal value, in the glove box, store the sealed bottle in the glove box Take out the commercial drying sheet inside, take out a piece of drying sheet, and stick this drying sheet in the middle of the metal sheet, the cross-sectional view is as follows figure 1 shown.

[0046] (2) Preparation of PDMS film layer

[0047] Place a piece of clean glass substrate in a petri dish, drop 2-3 drops of trimethylchlorosila...

Abstract

The invention belongs to the field of photoelectric device packaging, and in particular relates to a flexible device packaging method. A breathable insulating layer, a highly water-absorbing and oxygen-absorbing layer (dry sheet) and a flexible metal sheet with high water and oxygen barrier properties are arranged in sequence above the flexible device. The encapsulation method specifically includes: sequentially adhering a desiccant sheet and a breathable insulating layer material adsorbed with high-purity inert gas on one side of a clean and dry flexible metal sheet, and then encapsulating the flexible device through UV resin with high water and oxygen barrier properties. The invention has simple process, low package cost and can be used for the package of large-area devices.

Description

technical field [0001] The invention belongs to the field of device packaging, and in particular relates to a method for packaging flexible devices. Background technique [0002] The present invention relates to the fields of Organic Light Emitting Display (OLED for short) and Quantum Dots Light Emitting Diode Display (QLED for short), in particular to a packaging method for OLED and QLED devices. [0003] Due to their own series of advantages, OLED and QLED have become extremely competitive display devices with development prospects. Studies have shown that components such as water vapor and oxygen in the air have a great impact on the life of OLED and QLED devices. Therefore, effectively encapsulating the device and isolating the device from water and oxygen in the atmosphere can greatly prolong the service life of the device, thereby prolonging the life of the device including OLED and QLED. [0004] At present, the commonly used packaging methods are (1) the traditiona...
