[0075] Preparation of Glue A

[0076] 60 g of EM210  (2-phenoxyethyl acrylate, sold by Eternal Company) and 60 grams of 624-100  (epoxy acrylate, sold by Eternal Company) mixes, then adds 5 grams of Chivacure  BP was used as a photoinitiator (benzophenone, provided by Double Bond Chemicals) and stirred at 50° C. and a rotation speed of 1,000 rpm to form a glue A.

[0077] Preparation of Glue B

[0078] Solvent (40 g toluene), acrylate monomer (10 g dipentaerythritol hexaacrylate, 2 g trimethylolpropane triacrylate, 14 g pentaerythritol triacrylate), oligomer (28 g aliphatic amine Formic acid ester hexaacrylate [Etercure6145-100, Eternal company]) and photoinitiator (6 grams of 1-hydroxycyclohexyl phenyl ketone) are mixed, high-speed stirring, make about 60% of solid content and total weight about 100 grams Resin Formulation B'.

[0079] Solvent (27 grams of toluene, 13.5 grams of methyl ethyl ketone), 0.5 grams of acrylic microparticles [SSX-108, Sekisui Chemical Co., ...

Embodiment 1

[0088] The microstructure of the optical film prepared by the above method includes a repeating structure composed of a first region and a second region, wherein the first region contains a multi-peak columnar structure composed of two arc-shaped columnar structures, and the multi-peak arc In the shape columnar structure, the height of the valley line connecting two columnar structures is about 58% of the height of the lower height of the two adjacent columnar structures; and wherein the second region contains two single-peak prism columnar structures. Various characteristic tests were carried out, and the test results are shown in Tables 1, 2, 3 and 4.

Abstract

The invention discloses an integrated optical film, which belongs to the field of optical film. The optical film comprises a substrate and a microstructure layer positioned on one surface of the substrate, wherein the microstructure layer includes one or more first regions, each including at least one multi-peak columnar structure consisting of at least two columnar structures overlapping each other to form a joint structure and an arc-shaped columnar structure formed at the maximal height position; and the microstructure layer optionally includes one or more second regions, each including at least one single-peak prism columnar structure. The optical film of the invention can suppress the optical interference and can prevent scratch of the optical film due to contacting with other optical films or panels, thus obviating the cost of an upper diffusion film or a protection film and achieving good scratch resistance and high brightness gain.

Description

technical field [0001] The invention relates to an optical film, in particular to an integrated optical film applied to a liquid crystal display. Background technique [0002] The liquid crystal panel itself does not emit light, so the backlight module as a source of brightness is an important component of the LCD display function, and is very important for improving the brightness of the liquid crystal display. Currently, various optical films are used in the backlight module to provide an application that can increase the brightness of the LCD panel to make the light source most efficient without changing any component design or consuming additional energy. The most economical and simple solution. FIG. 1 is a simple schematic diagram of various optical films contained in a backlight module. As shown in Figure 1, the optical film contained in the general backlight module includes a reflective film (1) arranged below the light guide (2); and other optical films arranged ab...
