Embodiment 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) process the surface of ultra-thin glass with silane coupling agent, method is as follows: the ethanol solution of the silane coupling agent (isobutyltriethoxysilane) 95% of preparation, this solution is put into 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 ultra-thin glass by spin coating to obtain ultra-thin glass 1 after surface treatment with a silane coupling agent;

[0066] (2) Form an ITO layer 3 on the carrier glass 4, and further form an OC resin layer 2 capable of forming a chemical bond with the silane coupling agent on the ITO layer 3;

[0067] (3) Bond the carrier glass 4 to the surface treated with the silane coupling agent of the ultra-thin glass through the OC resin layer 2: after cleaning the s...

Embodiment 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 Finally, keep it for more than 2 hours, and then spray it evenly on the surface of ultra-thin glass to obtain ultra-thin glass 1 after surface treatment with silane coupling agent;

[0071] (2) form polyimide layer 5 on carrier glass 4;

[0072] (3) Under heating condition, under the effect of initiator and accelerator, the carrier glass 4 that has formed polyimide layer 5 is pasted on the surface that is processed by silane coupling agent of ultra-thin glass 1, forms self- From top to bottom is a multi-layer composite structure of carrier glass 4, polyimide layer 5 and ultra-thin g...

Embodiment 3

[0074] Compared with embodiment 2, the present embodiment differs only in that in the present embodiment, the formation method of the polyimide layer is as follows:

[0075] (a) After mixing hexafluorodianhydride, norbornene dianhydride, and 4,4'-diamino-2,2'-bistrifluoromethylbiphenyl, they are dissolved in N-methyl pyrrolidone and mixed uniformly to obtain Polyamic acid solution; Wherein, the mass ratio of monomer and solvent is 15 / 85;

[0076] (b) After the polyamic acid solution is chemically imidized, a polyimide having a norbornene group at the end is obtained;

[0077] (c) The polyimide solution obtained by dissolving polyimide in dimethylacetamide is coated on the carrier glass, heated to 180°C for 2 hours, and the solvent is removed to obtain the polyimide solution attached to the surface of the carrier glass. polyimide layer.

Abstract

The invention relates to the field of semiconductor, and in particular discloses an ultra-thin liquid crystal display and a production method thereof. The production method comprises the steps that the surface of ultra-thin glass is processed by a silane coupling agent, and a polymer layer capable of forming a chemical bond combination with the silane coupling agent is formed in carrier glass; the carrier glass is fitted with the surface, processed by the silane coupling agent, of the ultra-thin glass through the polymer layer. In addition, the production method further comprises the process that the carrier glass is stripped from the ultra-thin glass after the ultra-thin glass and the carrier glass are fitted well and a liquid crystal cell is produced. Stripping is achieved through an LLO technology or alkaline stripper soaking. According to the ultra-thin liquid crystal display and the production method thereof, through the improvement on fitting of the ultra-thin glass and the carrier glass and a stripping mode, the ultimate purpose that the problem of ultra-thin liquid crystal display volume production implementation (fitting and stripping) can be solved by utilizing existing equipment, technology and mode is achieved; the technology is simple, the cost is low, high rate of good product can be guaranteed, and wide market prospect is possessed.
