Description

Optical coordination optical film

The invention belongs to a film structure, in particular to a photo-coordinating optical film, which mainly utilizes the photocatalytic property of the nano-core shell particles, so that the nano-core shell particles are irradiated by visible light, and then each nano-core shell particle is obtained. Because of the generation of electron hole pairs, the surface has the same electrical charge, so that the molecules can be evenly matrixed in the organic glue, and then the magnetic field is applied to control the distance between the nano-core particles, and finally The glue is cured by light or heat, and the nano core shell particles are fixed in the coating layer to form a photo-alignment as an optical film.

The Flat Panel Display (FPD) display itself does not actively emit light, so a backlight is required to provide the light source, so the optical film plays an important role in the current FPD display industry.

The lens technology is BEF (Brightness Enhancement Film), which is mainly coated with UV resin on the Polyester optical film, and then transferred by the roller of the microstructure. It has the following disadvantages: 1. Due to the lenticular lens structure, it is easy to form a moire. 2. When viewing from a positive angle of view, it is brightened. In fact, the side angle is changed to a dark area without a brightening effect.

3M has developed a reflective brightness enhancement film DBEF (Dual Brightness Enhancement Film), which uses multi-layer film technology, which consists of nearly one thousand layers with special birefrigence characteristics, so that most of the original should be absorbed and lost. The S-polarized light (the linearly polarized light whose direction of the electric field is perpendicular to the incident surface) is mostly converted into usable effective P-polarized light (the direction of the electric field is parallel to the incident plane), which improves the brightness of the screen. The shortcomings: the thousand layers have a special birefringence stacking and extension, the processing cost is high; the stacking adhesion and the expansion coefficient are different, the popcorn effect is formed during construction or in use, the middle layer is separated; the rainbow interference color, the color effect Uniformity.

In addition, Japan Nitto Denko Co., Ltd. uses Cholesteric LC with a quarter wave film to divide the light pattern into two, and then repeat the cycle to obtain a similar brightening effect. The above-mentioned cholesteric liquid crystal has the disadvantages of: 1. forming an elliptically polarized light pattern, so it must be further trimmed into a linearly polarized light pattern by using a retardation film before being used by the liquid crystal; 2. The 1/4 wavelength film control direction At the same time, it has an effect on R, G, and B. Therefore, the technical application of such a cholesteric liquid crystal is difficult, and thus has a high cost. 3. Since the composition is cholesteric liquid crystal, it has a large influence on temperature.

There is also a method of increasing the brightness enhancement effect of an optical film by using "microlens diffusion technology". The disadvantage is that: one of the microstructures and the microstructures, such that the light leakage region can be formed not uniformly diffused to form a diffusion unevenness. 2. The ability of light to diffuse is related to the radius of curvature. It cannot be made large in relation to thickness and has low diffusion ability.

There is also a method for manufacturing an optical film by using "nano-added diffusion" technology, and the disadvantages thereof are as follows: 1. Particles of different sizes form uneven reflection and refraction for optical thickness (1/4λ), and light dispersion is formed. 2. Raw materials with small difference in high and low refractive index make the diffusion ability low. 3. No light channel design, light larger than the critical angle will have a large loss of total reflected light, so it is easy to form a low-penetration optical film.

The following is a comparison table of the advantages and disadvantages of the above several optical films:

As can be seen from the above, each of the conventional optical films has its disadvantages, such as poor light diffusion effect, complicated structure, or the need to use several optical films together, and the cost is too high.

And whether it is reflected or penetrating light, it contains part of P and S-polarized light, and the path of light is constantly changing direction, thus enabling light to diffuse.

Another object of the present invention is that when light is diffracted into light, the phase of the light is reversed by 180 degrees, the phase of the transmitted light is unchanged, and the reflected light is reflected again as the same phase, and the same phase is passed. The gap channel, the light from the same phase of different regions, and the brightness of the light is increased by the superposition of light.

Another object of the present invention is that after a plurality of light refractions and reflections, part of the P-polarized light and the S-polarized light are converted into P-polarized light, so that most of the S-polarized light that should be absorbed and lost is converted into liquid crystal. Utilize the effective use of P-polarized light.

The electric field and the magnetic field are perpendicular to each other and are in the same phase. They can transcend the physical bondage and transmit freely in the form of waves. In the magnetic field, electromagnetic force is working, thus changing the core-shell particles in the fluid. In the working state, when the surface of the particles are all of the same polarity, another magnetic field is generated between the particles to cancel the change of the magnetic field (the 定理 theorem), and the magnetic pressure is formed between the magnetic fields to move the particles in the opposite direction. This stress tensor belongs to the second order. (r = 2) tensor, so the core-shell particles will become a matrix distribution. The particles can be arranged in a uniform matrix in a UV organic gel, and finally the UV light is irradiated to solidify the particles in the organic gel to form a photo-coordinating optical film.

The following is a detailed description of the application principle of the visible light irradiation device, that is, the optical coordination theory: when the nano-core particle (100) is irradiated with light, the electricity is equal, positive and negative opposite charge electron hole pairs, when the magnetic field is applied, Hall effect electrons and holes are concentrated in different directions by Lorentz forces in different directions. An electric field is generated between the collected electrons and the holes. In quantum electrodynamics, according to Maxwell's equations (Maxwell's) Equations), an electric field that changes with time produces a magnetic field and vice versa. Therefore, an electric field in an oscillation generates an oscillating magnetic field, and an oscillating magnetic field generates an oscillating electric field. Thus, these continuously in-phase oscillating electric and magnetic fields together form an electromagnetic wave that can transcend material constraints and freedom. Pass in the wave. When the surface of the particles all have the same polarity, another magnetic field (the 定理 theorem) is generated between the particles to cancel the change of the magnetic field. The magnetic pressure is formed between the magnetic fields to move the particles in the opposite direction. This stress tensor (Stress Tensor) belongs to the first The second order (r = 2) tensor, so at a certain point in time, the core-shell particles will become a uniform matrix distribution.

When the nano-core shell particles (100) irradiated with visible light are arranged in the above matrix, a gap (X) is left between the matrix-arranged nano-core shell particles (100) to allow light to pass, such as the fourth The figure shows. When the nano-core shell particle (100) particles are larger than the optical thickness of the full wavelength of visible light, the reflected light in the visible light region is once again reflected through the gap (X), and the reflected light and the refracted light are also changed in the direction of the path. The path of light is constantly changing, thus allowing light to spread. When the reflected light is reflected again by the light into the light, the phase of the light is changed by 180 degrees, and the light that is in phase with the refracted light is reflected again, and the light passing through the gap (X) channel increases. When the incident angle of light is greater than the critical angle, the total reflection of light will change the path length of the optical path, and there will be loss of light passage. Due to the gap (X) channel design, the refractive index between materials will be different. The critical angle will also be different, and there is a function similar to the expansion of the critical angle, which reduces the loss of light passing through the total reflection, and increases the brightness of the light due to the superposition of light.

Among the nano-core shell particles (100) arranged in the above matrix, when the nano-core shell particle (100) particles are smaller than the optical thickness of the full wavelength of visible light, when the light is diffracted by a circular obstacle smaller than the wavelength particle diameter A bright spot (Poisson highlight) is formed behind the circular obstacle. The light from different zones is enhanced by the same phase, which greatly increases the illumination of the light, and its effect is similar to the focusing of the positive lens, thus having a light correction function. When the circular obstacle has an optical thickness of less than 400 nm, it does not reflect visible light, and the other meaning that no reflection occurs, and there is variation of the light component when there is reflection, for example, partial reflection of P light becomes S light, When the P light passes, it will not be decomposed into P and S light, so the polarization component of the light does not change, making it the best choice for upper diffusion.

By the above technical means, the optical coordination optical film (1) (1a) (1b) having the nano core-shell particle layer (11) (11a) has penetration, diffusion, brightness enhancement, light direction correction, and light. Efficient use of more than six functions such as function (polarization) and antistatic. Since the optical coordination optical film (1) (1a) (1b) can complete the finished product only through a simple light irradiation processing and optical positioning process, the processing cost is low, the yield is high, and thus the low cost and high market competition force. In addition, the optical coordination optical film of the invention has the following effects: 1. antistatic function; 2. increased penetration function; 3. high diffusion and high penetration function; 4. light-phase phase superimposed brightness enhancement function. 5. Reduce the light passing loss function due to total reflection. 6. The polarization component of the light passing through the Poisson bright spot does not change.
