preparation example Construction

[0037] The preparation method of the integrated structure of OLED screen body and fiber material comprises the following steps:

[0038] Place the working interface of the OLED screen downwards in the mold, lay fiber material on the upper surface and sides of the OLED screen, pour the adhesive from above the composite fiber material layer through a vacuum infusion process, uniformly penetrate and then cure , so as to obtain an integrated structure of OLED screen body and fiber material, just take it out.

[0039] The fiber material is a mixture of carbon fiber and glass fiber, and the electrode area of ​​the OLED screen is physically insulated from the fiber material.

[0040] As another embodiment, the fiber material includes alternately arranged carbon fiber cloth layers and chopped glass fiber mat layers, and the electrode area of ​​the OLED screen is isolated from the carbon fiber cloth layers by the chopped glass fiber mat layers.

Embodiment 1

[0042] Such as figure 1 As shown, the present invention provides an integrated structure of an OLED screen body and a fiber material, including an OLED screen body and a protective shell covering the non-working interface of the OLED. In the pouring process, the binder is poured into the fiber material, and after curing, the fiber material and the OLED screen body 4 form an integrated structure.

[0043] The fiber material in this embodiment is composed of one layer of carbon fiber cloth layer 1 and one layer of chopped glass fiber mat layer 2, wherein the chopped glass fiber mat layer 2 is arranged on the non-working interface of the OLED screen body 4 and the carbon fiber cloth layer 1 In between, the electrode region 3 of the OLED screen is isolated from the carbon fiber cloth layer 1 by a chopped glass fiber mat layer 2 . Generally, there are two kinds of carbon fiber cloth layers: 0.111 mm and 0.167 mm. The thickness of the carbon fiber cloth layer used in this embodimen...

Embodiment 2

[0052] Such as image 3 As shown, the present invention provides an integrated structure of an OLED screen body and a fiber material, including an OLED screen body and a protective shell covering the non-working interface of the OLED. In the pouring process, the binder is poured into the fiber material, and after curing, the fiber material and the OLED screen body 4 form an integrated structure.

[0053] The fiber material of this embodiment is composed of a carbon fiber cloth layer 1, a chopped glass fiber mat layer 2 and a carbon fiber cloth layer 1 that are superimposed, wherein the carbon fiber cloth layer 1 that is in contact with the OLED screen body 4 is connected to the electrode area of ​​the OLED screen body 4 (4) Cutouts are provided at the corresponding positions, and the electrode area (4) is not in contact with the carbon fiber cloth layer 1 so as to realize insulation. In this embodiment, the cloth layer of fiber material, the felt layer of fiber material, and ...

Abstract

The present invention provides an OLED (organic light emitting device) screen body and fiber material integrated structure and a preparation method thereof. The OLED screen body and fiber material integrated structure comprises an OLED screen body and a protective shell covering an OLED non-working interface; the protective shell is made of a fiber material; and a binder is injected into the fiber material through a vacuum infusion process, after being solidified, the fiber material forms an integrated structure with the OLED screen body. According to the OLED screen body and fiber material integrated structure and the preparation method thereof of the invention, a suitable fiber material is selected according to the temperature of the use environment of an OLED product, and the structure and process of the fiber material are designed, so that the fiber material can be composited and integrated with the OLED screen body; and the OLED product can be thin, and the shape of the OLED product can be designed flexibly, and the OLED screen body can be effectively protected, so that the OLED screen body has little possibility of being damaged.

Description

technical field [0001] The invention relates to the technical field of OLED screen body protection, in particular to an integrated structure of an OLED screen body and a fiber material and a preparation method thereof. Background technique [0002] After nearly 30 years of development, organic electroluminescent devices (English full name Organic Light Emitting Device, referred to as OLED) as the next generation of lighting and display technology, has a wide color gamut, fast response, wide viewing angle, no pollution, high contrast, The advantages of planarization and thinness have been applied to a certain extent in lighting and display. However, the thin and light OLED screen makes it easy to break, and a protective case must be added when it is applied to products. [0003] In general, the protective shell of the OLED screen not only needs to have high strength to ensure that the screen is not damaged due to deformation, but also needs to have high damping to reduce the...
