preparation example Construction

[0073]The preparation method of the polymerization composition provided by the present invention can be obtained directly by mixing each component in the composition. In preferably, in order to shorten the mixing time, mixing is preferably at 40 ° C-80 ° C.

[0074] The invention also provides a backlight module, which includes a brightening film, which is a brightening film formed by the cingering of polymerization combinations as described above.It can be coated with a polymerized pair of polytinate (PET) to form a coating with prism patterns by applying a polytarbinic acid ethyl (PET), which can be obtained.The brightening film formed by the aggregate composition.Then, the backlight module is made by combining with conventional components including lamps, light guide boards, and other known optical membranes.According to the embodiments of the present invention, the thickness of the brighter membrane is 15-25 microns, preferably, and the thickness of the bright film is 20 micro...

Embodiment 1-4

[0078] The raw materials used in Example 1-4 are as follows:

[0079] (A): Type I 1 The monomer compounds shown:

[0080] Will Heated to the nitrogen protection in the DMF to the reaction of nitrogen protection to 80 ° C for 5 hours, and then add the production product, and then add acrylic acid to a toluene to the 75 ° C to return to the return reaction for 2 hours to obtain the compound shown in the type I1;

[0081] (B): Light Treaster I173 (purchased from Steam Performance Company);

[0082] (C): The cross -linked agent SR294 (purchased from Sartomer);

[0083] (D): diluent PBA-001 (purchased from Shanghai to Germany chemistry);

[0084] Prepare the raw materials in Table 1, mix the above raw materials together, and heat it at 50 ° C until it forms a uniform and transparent colloidal polymer.Apply the above -mentioned preparation of glue polymer to the polypenic acid ethyl (PET) substrate (PET) substrate (PET).The thickness of 20 microns is brightened.

In addition, the invention also provides a preparation method of the monomer compound in the polymerizable composition, and a backlight module and a liquid crystal display with the brightness enhancement film.

Description

Technical field [0001] The invention involves the field of LCD display, which specializes in a backlight module and LCD monitor prepared by UV monomer and its preparation methods, polymerization compositions, and the use of the ultraviolet polymerization composition. Background technique [0002] The advantages of LIQUID CRYSTAL DISPLAY (LCD) have gradually replaced the traditional cathode ray tube display with the advantages of light, thin, short, small, low calories, low power consumption, and no radiation.Upper computer, text processor, desktop monitor, TV, camera, etc.Generally speaking, the liquid crystal display is mainly composed of two parts: panel and backlight module. The panels include conductive glass, LCD, matching film, color filter, polarizing tablets, driver integrated circuits, etc. The panel itself is not glowing, so it is used as the brightnessThe backlight module of the source is an important component of the LCD display function. The backlight module includes...
