Description
Technical field
The present invention relates to quantum dot films, and self-isolation may be implemented with the edge of caudacoria more particularly to being cut in process
A kind of self-enclosed quantum dot film in edge.
Background technology
Quantum dot film has been applied to liquid crystal display, make the colour gamut of liquid crystal display be increased to 100%NTSC with
On, hence it is evident that improve the accuracy and colour vividness that color is shown.According to existing production technology, quantum dot film is using volume
The mode of volume is manufactured, before quantum dot film to be installed to display equipment, needs to be wanted according to the size of distinct device
It asks and quantum dot film is cut.After quantum dot film is cut off, (China can be exposed in the quantum dot of quantum dot film edge
104937729 A of patent CN), it will produce two harmful effects in this way：(1) quantum dot of film edge may fall off and cause
Environmental pollution；(2) quantum dot of film edge is directly exposed in the environment containing vapor and oxygen, and fluorescence is more prone to
Quenching, keeps the fluorescence of film edge dimmed.
To solve the above-mentioned problems, people attempt to change the production procedure of quantum dot film, such as by the company of quantum dot glue
Continuous coating is changed to intermittent coating (104848168 A of Chinese patent CN), and quantum dot glue-coating is being surrounded by edge sealing adhesive
In region, finally cut in edge sealing adhesive region.Compared with prior art, it is the shortcomings that this method：(1) painting is needed replacing
Cloth equipment；(2) uniformity that intermittent coating is not coated with continuously is good；(3) technique for increasing coating edge sealing adhesive, reduces life
Produce efficiency；(4) dispensing area of quantum dot glue needs to precisely align with the region that edge sealing adhesive surrounds, and increases technical difficulty,
Reduce product qualification rate；(5) a kind of quantum dot film of size can only correspond to a kind of cutter size, the size adaptability of product
Difference；(6) in order to ensure quantum dot layer in the centre of film, quantum dot film needs are precisely aligned with cutting mould, increase skill
Art difficulty, reduces product qualification rate；(7) location hole needs to make in edge sealing adhesive region so that and edge sealing adhesive peak width is larger,
It increases the width of display device bezel and influences beauty.
In addition, people attempt to cover quantum in the length of quantum dot film edge coating binder or extension water oxygen barrier layer
Point film edge (104501043 A of Chinese patent CN), compared with prior art, in lacking for quantum dot film edge coating binder
Putting is：(1) production technology is increased in quantum dot film edge coating binder, reduces production efficiency；(2) in hundreds of microns of thickness
Film edge be coated relatively difficult, and corresponding machinery equipment needs to customize；(3) for diaphragm upper Positioning holes one kind
Film internal edge and complex outline edge are difficult to be coated.Compared with prior art, extend the length of water oxygen barrier layer to cover
The shortcomings that lid quantum dot film edge is：(1) it needs, in quantum dot layer upper and lower surface sticking water oxygen barrier layer, to increase a laminating adhesive
Technique, reduce production efficiency；(2) a kind of quantum dot film of size can only correspond to a kind of cutter size, and the size of product is suitable
Answering property is poor；(3) in order to ensure quantum dot layer in the centre of film, quantum dot film needs are precisely aligned with cutting mould, are increased
Technical difficulty, reduces product qualification rate；(4) location hole needs to make in extended water oxygen barrier layer region so that extends
Water oxygen barrier layer peak width it is larger, increase display device bezel width and influence beauty.
Invention content
In order to solve the above-mentioned problems of the prior art, overcome existing method there are the shortcomings that, the purpose of the present invention exists
In a kind of self-enclosed quantum dot film in edge of offer.
The present invention is equipped with quantum dot layer, is equipped with water oxygen barrier layer in the upper and lower surface of quantum dot layer, quantum dot layer is by liquid
Body microcapsules, quantum dot, diffusion particle, matrix resin and coalescents composition, liquid microcapsule are evenly distributed on quantum dot layer
In, the liquid microcapsule is equipped with liquid capsule-core, and solid-like cyst wall is equipped with outside liquid capsule-core.
Described matrix resin can be selected from organic siliconresin, polyacrylate, isocyanates, epoxy resin, polyurethane, polyene
At least one of hydrocarbon resin, light-cured resin etc..
The diffusion particle can be selected from least one of organic filler, inorganic particulate etc., preferably poly-methyl methacrylate
Ester particle and organic silicon particle.
The coalescents can be selected from least one in levelling agent, substrate wetting agents, crosslinking accelerator, organic solvent etc.
Kind.
The liquid capsule-core can be selected from polyester polyol, isocyanates, epoxy resin, polymercaptan, anhydride compound,
One in aminated compounds, liquid low-molecular polyamide, light-cured resin, hydrogeneous silicones, vinyl polysiloxane etc.
Kind.
The solid-like cyst wall can be selected from polyurethane, polyacrylate, vistanex, ethylene-vinyl acetate copolymerization
One kind in object, amino resins etc..
The grain size of the liquid microcapsule can be 0.1~20 μm, preferably 1~10 μm.
At least one liquid capsule-core can be used in the liquid capsule-core.
After the present invention is cut off, the liquid microcapsule in incision can be cut off, the film forming in liquid microcapsule
Liquid, which can ooze out, to be come and mutually merges, liquid under the action of surface tension to film edge carry out homogeneous immersion, then room temperature,
Liquid meeting film-forming, plays the role of the edge of quantum dot film closed under the conditions of heating or ultraviolet light.The closing
Process is not limited by film edge profile, and envelope can be also played to the film internal edge of complicated film edge profile or location hole one kind
The effect closed.Production equipment and the technological process for manufacturing the self-enclosed quantum dot film in the edge are same as the prior art, are not necessarily to volume
Outer equipment investment will not reduce production efficiency.
