Problems solved by technology

However, this pocket-type technology requires another layer (Metal Canister) or glass (Glass) on the substrate, which will have the following negative effects: (1) increase the thickness of the display panel; (2) paste the substrate The adhesive (Sealant) applied during the process with the metal cap (Capsule) may release some active gases, thereby shortening the life of the accessories; (3) components such as oxygen and moisture in the air can penetrate through the adhesive (Sealant) ), shorten the life of the accessories; (4) The application quality of the adhesive (Sealant) may cause the aging of the accessories; (5) The inside of the metal cap (Capsule) is injected with a hygroscopic agent to absorb the moisture inside the metal cap (Capsule), The raw material cost of the product is increased; (6) The sealing process of the substrate and the metal cap (Capsule) takes a long time and requires careful management, so the investment in equipment is increased; (7) The display panel accessories with a relatively large plane area, It is difficult to keep the metal cap (Capsule) (Metal Can) flat during the process
Due to the existence of these problems, the production efficiency of prior art is relatively low

Embodiment 1

[0024] Such as Figure 4 Shown, the manufacturing process of parylene dimethyl (Parylene) film: heating dimer (Dimer) parylene dimethyl (Di-para-xylylene) to 150 degrees Celsius under the pressure of 1.0 torr , decomposed into monomer (Monomer) polyparaxylylene dimethyl Paraxylylene, and then sprayed into the reaction chamber (Chamber) at a pressure of 0.5 Torr not higher than 680 degrees Celsius, and at a pressure of 0.1 Torr at 25 degrees Celsius The formation of polymer (Polymer) poly-p-phenylene dimethyl Poly (para-xylylene), that is, the formation of a film.

Embodiment 2

[0026] Such as Figure 5 As shown, the silicone resin refers to a polymer (Polymer) containing an organic group connected by a Si-O-Si combination of silicon and oxygen. Therefore, it has both organic and inorganic properties. That is, analyzing the molecular structure of silicone resin, due to the combination of Si-O-Si, it has inorganic properties such as heat resistance, chemical stability, wear resistance, and high gloss; at the same time, because of the organic properties of its side chains, it has Excellent reactivity, solubility, productivity, etc. According to the different forms of silicone resin, it is divided into oil (oil), rubber (Rubber), resin (resin) and other types. The higher the degree of cross-linking of silicon (Silicon Resin), the lower the activity and stretchability of the molecule, and the higher the hardness. The product with extremely high cross-linking density is silicone resin (Silicone Resin).

Embodiment 3

[0028] Such as Figure 6 As shown, the chemical basic unit of epoxy resin must contain epoxy (Epoxy) structure, which is usually produced by neutralizing epichlorohydrin and bisphenol A. Epoxy resins are difficult to use alone and require the addition of a hardener. Therefore, epoxy resins in the strict sense are intermediate products. Because bisphenol A epoxide is produced by the reaction of 2,2-bis-p-hydroxyphenylpropane BPA (Bisphenol A) and chloromethoxycyclopropane ECH (ie Epichlorohybrine), it belongs to the benzene ring nucleus (Bisphenol A), so it is difficult to rotate freely . Therefore, its chemical resistance, adhesive force, toughness, high temperature resistance and other properties are outstanding. Moreover, the ether (Ether) group inside its molecule can improve drug resistance and plasticity. Hydrophilic hydroxyl groups and hydrophobic hydrocarbon groups are regularly arranged, so its adhesive force is excellent.

Abstract

A process for preparing the organic electroluminescent display screen covered by protecting membranes is characterized by that the carrier substrate of the display screen is sequentially covered witha film able to absorb water and oxygen, an inorganic protecting film for preventing and stopping air, and a high-molecular film able to prevent penetration of external water and oxygen. Its advantages are thin thickness, low cost and high productivity.

Description

technical field [0001] The invention relates to a method for manufacturing an organic electroluminescent display panel in a FPD (liquid crystal display), in particular to a method for manufacturing an organic electroluminescent display panel covered with a protective film. Background technique [0002] Conventionally, in order to protect the organic matter of the organic display panel components, a skin (Can) or glass is generally pasted on the substrate on which the display panel components have been formed. However, this will increase the thickness and production cost of the display panel, and make the manufacturing process of the display panel overly complicated, which will directly lead to problems such as excessive equipment investment and reduced production efficiency. [0003] The structure of the organic electroluminescent display panel in the prior art includes a positive electrode (ITO or IXO) that supplies positive charges to the plate, a positive charge injection...
