Problems solved by technology

Depend on Figure 3 to Figure 6 It can be seen that in the existing ADS mode liquid crystal display, in order to avoid the overlapping of the polyimide coating area and the frame sealant coating area, it is necessary to design different APR versions for different sizes of liquid crystal display products, and the design of the APR version is more complicated. LCD production costs are high

Embodiment 1

[0072] Example 1: Preparation of frame sealant 1

[0073] Put the epoxy resin shown in 100g formula (2) and 0.05g polymerization inhibitor p-hydroxyanisole into 500ml four-necked flask, wherein four are respectively connected with stirrer, condenser tube, thermometer and dropping funnel, put 53g The acrylic acid represented by formula (3) and 1.5 g of catalyst tetraethylammonium bromide were put into the dropping funnel, and the four-necked flask and the dropping funnel were fixed on the iron stand, and the preheating temperature was 70°C. Stir the solution in the four-necked flask, slowly drop the mixed solution of tetraethylammonium bromide and acrylic acid at a rate of 1 drop / second, after the dropwise addition, raise the temperature to 100°C, react for 8 hours, and cool to obtain the sealing frame of the present invention Glue 1.

Embodiment 2

[0074] Example 2: Preparation of frame sealant 2

[0075] Put the epoxy resin shown in 100g formula (2) and 0.05g polymerization inhibitor p-hydroxyanisole into 500ml four-necked flask, wherein four are respectively connected with stirrer, condenser tube, thermometer and dropping funnel, put 53g The acrylic acid represented by formula (3) and 1.5 g of catalyst tetraethylammonium bromide were put into the dropping funnel, and the four-necked flask and the dropping funnel were fixed on the iron stand, and the preheating temperature was 70°C. Stir the solution in the four-necked flask, slowly drop the mixed solution of tetraethylammonium bromide and acrylic acid at a rate of 1 drop / second, after the dropwise addition, raise the temperature to 100°C, react for 8 hours, and cool to obtain the sealing frame of the present invention glue2.

Embodiment 3

[0076] Embodiment 3: Preparation of frame sealant 3

[0077] Put the epoxy resin shown in 100g formula (2) and 0.05g polymerization inhibitor p-hydroxyanisole into 500ml four-necked flask, wherein four are respectively connected with stirrer, condenser tube, thermometer and dropping funnel, put 53g The acrylic acid represented by formula (3) and 1.5 g of catalyst tetraethylammonium bromide were put into the dropping funnel, and the four-necked flask and the dropping funnel were fixed on the iron stand, and the preheating temperature was 70°C. Stir the solution in the four-necked flask, slowly drop the mixed solution of tetraethylammonium bromide and acrylic acid at a rate of 1 drop / second, after the dropwise addition, raise the temperature to 100°C, react for 8 hours, and cool to obtain the sealing frame of the present invention glue3.

Abstract

The invention provides a frame sealing adhesive for a multi-dimensional electric field mode liquid crystal display panel, a manufacture method of the frame sealing adhesive, a transfer print version, a coating method of a polyimide alignment layer, a liquid crystal display panel and a display device. The frame sealing adhesive is an epoxy acrylate prepolymer as shown in a formula (1), wherein R<1>, R<2>, R<3> and R<4> are independently xenyl, naphthalene group or para-alkyl aryl substituent group, wherein the para-alkyl aryl substituent group contains 1 to 2 benzene rings, and alkyl in a para position relative to aryl contains 1 to 7 carbon atoms; and R<5> is H or hydrocarbyl. By adopting the frame sealing adhesive, the control to the boundary range of polyimide in the traditional polyimide alignment layer coating process can be removed; ADS (Advanced Design System) mode liquid crystal display products of different dimensions can use the same APR (Apache Portable Run-time libraries) version; the design and manufacture of the APR version are simplified; the coating process of the polyimide alignment layer is optimized; and the production cost of a liquid crystal display can be decreased.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a frame sealant for a multi-dimensional electric field mode liquid crystal panel and a manufacturing method thereof, a transfer plate for a liquid crystal display, and a polyimide alignment film for inducing liquid crystal alignment in a liquid crystal display Coating method, liquid crystal display panel and display device. Background technique [0002] Advanced Super Dimension Switch technology (ADvanced Super Dimension Switch, AD-SDS, referred to as ADS), its core technical characteristics are described as: the electric field generated by the edge of the slit electrode in the same plane and the gap between the slit electrode layer and the plate electrode layer The generated electric field forms a multi-dimensional electric field, so that all oriented liquid crystal molecules between the slit electrodes in the liquid crystal cell and directly above the electrodes can be rotat...
