Description of the Invention: [Technical Field] The present invention relates to an optical glue mixture for a bubble elimination process, particularly for an optical glue mixture containing photocurable glue and solid support particles. [Prior Art] Optical components are one of the indispensable parts of many electronic devices, and their quality directly affects the display quality of electronic devices. In general, in the manufacturing process of optical components, a process of bonding or bonding an optical substrate is often involved, for example, bonding a glass substrate to a glass substrate or a glass substrate to a non-glass (eg, polymerization). The process of substrate bonding. Hard-to-hard optic glass bonding, yield is a key factor in profitability. Generally speaking, in the bonding process, the generation of bubbles in the optical colloid is unavoidable due to the limitation of the bonding equipment. Therefore, in order to solve this problem, both the self-made process and the material property are required to be started; The specific solution is to wait for the process. The process waits for the optical substrate to be bonded after the initial bonding, 'not pre-cured, and waits until the curing, waiting for the work to be left in the optical glue. The bubbles have enough time to automatically cancel, and the 'waiting time' is positively related to the volume of the bubble. In addition, the right is on the optical substrate used in the bonding process, and there is a further printed and printed circuit for the logo of the company (Google), if it is UV-cured, The problem of overflowing or delamination of the uncured optical colloid is often caused during the waiting process of the process. SUMMARY OF THE INVENTION The present invention discloses a novel optical in view of the above-mentioned shortcomings of the prior art. Glue mixture to solve the problem of the above-mentioned local point pre-cure treatment process time and the problem of optical colloid overflow or adhesive layer peeling. Reaching the subject matter of the subject "To achieve the above purpose, the present invention provides a combination of two dollars. An optical glue mixture comprising a photocurable adhesive and a solid '% branch particle' wherein the photocurable adhesive may comprise a colloid of multiple curing routes such as uv curing, heat curing or anaerobic curing, and Preferably, the solid support particles are uniformly distributed in the photocurable adhesive by adding a certain amount of solid support particles to the photocurable adhesive. Applying the optical glue mixture to a piece of optical substrate, using the solid support particles therein to maintain a constant height, while maintaining the other optical substrate with a uniform gap height to cover the optical glue mixture, and the final direction of the glue layer The degree control can be adjusted by another process. ^ ', the above description is different from the traditional process of using only liquid uv glue. This optical glue mixture can use the shed state to hold the gift particles to maintain the optical base. The gap height between the two reduces the dependence on the fixing mechanism, and avoids the occurrence of the gelation during the waiting process in the bubble elimination process, and reduces the time required for the process waiting; at the same time, if the heat curing is further combined with the optical solid 201243009, etc. The multiple curing route can avoid the colloid overflow, or less, and the optical glue mixture and the method thereof can greatly improve the yield of the traditional process. [Embodiment] ^充=明本The object, features and effects of the invention are such that those of ordinary skill in the art of the invention can understand the content of the invention and can The specific ##, the detailed description of this (4) line is as follows.

In addition, in the present invention, the value is understood to be covered under the premise that the number of knives can be solved to have the digital effective position. From 35 〇 to 4 牛牛列's 'number 40 should cover the formula from (4) to (10), then it should be understood that the preparation of the mixture of two kinds of hairpins. One of the examples of the optical glue mixture mainly includes the following two types. 77. Photocurable adhesive and solid support particles.: The medium light 111 resin uses various commercially available glues that can be cured by light, and may include, but is not limited to, polychlorite, An optical grade sputum of propyl ketone, methacrylic acid or epoxy. For example, in the present invention, a photocurable adhesive which can be used is a liquid of Sony Chemicd, and its product model is srv_i32i. In addition, the type of optical filler can also be a single-dose or two-dose (ie, containing a main agent and a hardener), and the curing method can be multiple curing methods such as heat curing, optical curing or anaerobic curing, but Except for this, the optional optical fillers include polyoxin, epoxy, etc. In the present invention - the 'optical filler' is the product SE-mo of Qiao Yue Industrial Co., Ltd. Since the characteristics, composition and use of the photocurable adhesive are known to those of ordinary skill in the art, it is described herein. 6 201243009 In the present invention, the type of solid support particles that can be used is generally It is not particularly limited as long as the optical glue mixture formed can conform to the optical requirements/specification of the final product. For example, the solid support particles can be inorganic materials such as glass, or organic materials such as organic polymers. The size of the solid support particles is mainly related to the target gap height between the two optical substrates, and the size range can be larger than 〇 micron and not large. Between the target gap height 110%; more preferably, the target gap height is greater than 90% and the target gap height is 110%, for example, the target gap height is 100 microns, then the size More preferably, the range may be greater than 90 microns and no greater than 110 microns. In a specific embodiment, the solid support particles comprise a polymer. Further, the polymer is preferably selected from a hardness not greater than that to be bonded. At least one of the optical substrates' and preferably has a high light transmittance, such as greater than about 95%. In a specific embodiment, the refractive index of the solid support particles and the refractive index of the photocurable adhesive The same or similar, such as between 95% and 105% of the refractive index of the photocurable adhesive. In one embodiment, the solid support particles are composed of a polymer such as PC, PMMA or PET. Since the solid particles of these materials are commercially available, they will not be described here. To prepare the optical glue mixture of the present invention, the solid support particles can be processed first, for example, according to the desired target gap height and optical properties, to obtain the particle size according to the specific mesh standard, 7 after 201243009 The particles having the same particle size are added to the photocurable gel and the mixture is evenly mixed. Generally, the number of solid support particles added per unit volume of the photocurable adhesive is not particularly limited, but it is preferred that the formed optical glue mixture contains at least 50 solid support particles in 1 ml, more preferably The optical glue mixture contains at least 2 Torr to 1 固态 of solid support particles in 1 ml of the best system to contain at least 2 (9) to 5 固态 solid support particles in 1 ml of the optical glue mixture. Accordingly, the present invention allows a unit volume of glue to have a certain height and structural strength by adding solid particles in a liquid glue, and at the same time, by using the forged particles as a support, two pieces of optics can be used. A certain height is maintained between the substrates, thereby overcoming the problem of the silicone produced by simply using the glue containing only the liquid component. In the case of the opening method, the choice of * σ ..... is also the choice of the optical characteristics, for example, I = meet the specific transmittance or refractive index. To avoid the penetration of light, the solid support particles can be selected == preemptive, for example, the transmittance is greater than about % η. In addition, in order to avoid the light ^, the Japanese people have a handle larger than about the support of the chest, the light-refractive light curable adhesive and the solid-state made the second good effect of the solid-state support 2 === the same or similar refractive index. , and the first curable adhesive is Μ (air is D, then ^ if the refractive index material of the photocurable adhesive is used as the phase cut, the M ratio is between 1.3 and 1.5 or the refractive index is selected to be photocurable. Win 8 201243009 = Refractive index is between 98% of the photocurable adhesive to the material of the brain as a solid support particle. The material can be turned into a specific hardness as a solid support particle. For example, a material of an optical substrate that does not conform to the hardness may be selected as a solid support particle, such as U 'there is no need to worry about the fact that the solid support particles will be scraped during the bonding process' and may increase The process can be re-read. For example: two pieces of stickers, " the substrate is glass, then you can choose materials that meet specific optical requirements (such as = refractive index, light transmittance, etc.) and hardness is not greater than glass: solid '€ Domain particles. The domain is doubtful, (4) the material of the cutting particles to The materials of the substrate are the same or similar, and may be different or not in some embodiments. The optical glue mixture may include other components in addition to the supportable particles, only = the knife does not apply to the optical glue The adhesive properties or optical properties of the mixture may have a good effect. + In addition, it should be noted that the optical glue mixture of the present invention is understood to include a liquid form optical glue mixture before curing, and also a solid form optical glue. Mixture. Use of Mixture To apply the optical glue mixture of the present invention to an optical substrate, two optical substrates (hereinafter referred to as "first optical substrate" and "^" optical substrate") may be provided. In general, the choice of optical substrate type is not special: 9 201243009, and includes specific optical properties (such as light transmittance, refractive index, etc.), such as lenses, films, etc. In addition, two optical bases The materials of the materials may be the same or different. In one embodiment, the optical substrate selected may be any one of PC, PMMA and glass. The process steps disclose a specific embodiment for eliminating the bubble process: (1) providing an optical glue mixture for bonding on a surface of a first optical substrate, the composition of which is as described above, and mainly comprises a a photocurable glue and a solid support particle, wherein the application amount of the optical glue mixture may depend on the gap height between the optical substrates, but in one embodiment, the optical glue mixture at any application point The photocurable adhesive and the solid support particles are simultaneously contained. Further, in another specific embodiment, the optical adhesive mixture may be applied in an amount of between 0.01 ml and 0.1 ml. (2) The optical adhesive mixture After the application, a second optical substrate can be covered onto the optical glue mixture, wherein the optical glue mixture contains a solid component, thereby maintaining a certain gap height between the two optical substrates and supporting The second optical substrate is such that it does not contact the first optical substrate. (3) Thereafter, since the size of the solid support particles in the optical glue mixture may not coincide with the target gap height, a uniform external force may be applied to bring the two optical substrates to the target gap height. In addition, in another embodiment, the liquid photocurable adhesive can be pre-cured in a localized manner by illumination to provide a certain adhesive force between the two optical substrates. 201243009 (4) Wait for the bubble generated in the Μ curing gel to be automatically dissipated. In addition, in another embodiment, an antifoaming agent may be added to the mixture of the material to accelerate the elimination of the bubbles, wherein the ratio of the defoaming agent to the optical gel is 2GG ppm to 5GG ppm. The antifoaming agent can be a commercially known product for the elimination of photocurable colloidal bubbles. Among them, since the solid component in the optical glue mixture can provide a certain mechanical strength, the phenomenon of gelation of the photocurable colloid between the two optical substrates can be avoided. (5) Finally, the photocurable adhesive is cured to bond the two optical substrates. In one embodiment, the photocurable adhesive can be cured by multiple curing routes such as heat curing, optical curing or anaerobic curing. The invention has been described herein in terms of the preferred embodiments of the invention, and it should be understood by those of ordinary skill in the art that the present invention is not intended to limit the scope of the invention. It should be noted that variations and permutations equivalent to the embodiments are considered to be within the scope of the invention. Therefore, the scope of the invention is defined by the scope of the following claims. [Simple description of the schema] Benefits. Chuan, [Main component symbol description] None.
