Example Embodiment
[0063] Example 1
[0064] This embodiment provides a method for manufacturing an ultra-thin liquid crystal display, which specifically includes the following steps (see figure 1 ):
[0065] (1) Treat the surface of the ultra-thin glass with a silane coupling agent, the method is as follows: Prepare a 95% ethanol solution of the silane coupling agent (isobutyltriethoxysilane), put the solution into the liquid supply tank and After it is heated to 80-90°C, it is maintained for more than 2 hours, and then it is evenly coated on the surface of the ultra-thin glass by spin coating to obtain the ultra-thin glass 1 after surface treatment with a silane coupling agent;
[0066] (2) An ITO layer 3 is formed on the carrier glass 4, and an OC resin layer 2 capable of forming a chemical bond with the silane coupling agent is further formed on the ITO layer 3;
[0067] (3) Laminating the carrier glass 4 to the surface of the ultra-thin glass treated by the silane coupling agent through the OC resi...
Example Embodiment
[0068] Example 2
[0069] This embodiment provides a method for manufacturing an ultra-thin liquid crystal display, which specifically includes the following steps (see figure 2 ):
[0070] (1) Treat the surface of the ultra-thin glass with a silane coupling agent, prepare an aqueous solution of the silane coupling agent (isobutyltriethoxysilane), put the solution into the liquid supply tank and heat it to 80-90°C After that, it is maintained for more than 2 hours, and then it is evenly coated on the surface of the ultra-thin glass by spraying to obtain the ultra-thin glass 1 after surface treatment with a silane coupling agent;
[0071] (2) A polyimide layer 5 is formed on the carrier glass 4;
[0072] (3) Under heating conditions, the carrier glass 4 forming the polyimide layer 5 is attached to the surface of the ultra-thin glass 1 treated by the silane coupling agent under the action of the initiator and the accelerator to form a self From top to bottom is a multilayer composite ...
Example Embodiment
[0073] Example 3
[0074] Compared with embodiment 2, the difference between this embodiment and embodiment 2 is only that in this embodiment, the method of forming the polyimide layer is as follows:
[0075] (a) After mixing hexafluorodianhydride, norbornenic anhydride, 4,4'-diamino-2,2'-bistrifluoromethyl biphenyl, dissolve in N-methyl pyrrolidone and mix uniformly to obtain Polyamic acid solution; wherein the mass ratio of monomer to solvent is 15 / 85;
[0076] (b) After chemical imidization of the polyamic acid solution, a polyimide with a norbornene group at its end is obtained;
[0077] (c) The polyimide solution obtained by dissolving the polyimide in dimethylacetamide and coating it on the carrier glass. The temperature is raised to 180°C for 2 hours, and the solvent is removed to obtain a surface of the carrier glass. Layer of polyimide.
