The principle and application of polarizer?? Uses of polarizers

The full name of the polarizer should be polarized light sheet, those who have studied physics should know what polarized light is, the imaging of liquid crystal display must rely on polarized light, all liquid crystals have two polarized light sheets before and after are closely attached to the liquid crystal glass, forming a liquid crystal sheet with a total thickness of about 1mm. If any polarizer is missing, the LCD will not be able to display the image.

Polarizer The polarizer is replaced because the polarizer facing the eye of a normal LCD monitor is frosted to dissipate surface reflections and scatter light to increase the viewing angle of the LCD. For the projector, any scattering will cause a loss of light, and the ideal state of the LCD used in the projector should be a 0-degree viewing angle, that is, if you look at the LCD in the vertical direction, there will be no light. Of course, this is impossible to achieve, but the closer to the 0 degree viewing angle, the higher the utilization rate of light, so after replacing the frosted polarizer with a flat polarizer, the brightness of the projector to the wall will be greatly improved, in my personal estimate, it can be increased by about 50-80%, which is why the polarizer should be replaced.

Polarized lens standard.

Polarized lenses are globally recognized as the most suitable lenses for driving. When light is reflected from the surface of an object, it is partially polarized to produce glare. The opposite effect of glare - enhance brightness and reduce color saturation; The outline of the object becomes blurred, and the glasses are tired and uncomfortable.

The polarizer is made according to the principle of polarization of light, which has the special function of effectively eliminating glare, allowing the driver to improve vision and increase driving pleasure.

Resources.

The function of the polarizer is to absorb the light from other directions of natural light, and only retain the light in one direction that needs to pass through, resulting in polarized light.

At present, polarizers are used in liquid crystal displays and 3D eye lenses.

LCD, OLED and other industriesPolarizersThe main application fields, non-main application fields include polarization photography, infrared polarizers, ultraviolet polarizers, polarizer photoelastic effect testing, etc.

The full name of polarizer is polarized light.

Film, the imaging of the liquid crystal display must rely on polarized light, all liquid crystals have two polarized light sheets in front and back close to the liquid crystal glass, forming a total thickness of about 1mm liquid crystal sheet.

Polarized lenses are globally recognized as the most suitable lenses for driving. When light is reflected from the surface of an object, it is partially polarized to produce glare.

The opposite effect of glare - enhance brightness and reduce color saturation; Blurring the outline of objects, making eyes tired and uncomfortable. The polarizer is made according to the principle of polarization of light, which has the special function of effectively eliminating glare, allowing the driver to improve vision and increase the pleasure of driving.

The basic structure of the polarizer consists of the middle PVA (polyvinyl alcohol, two layers of TAC (cellulose triacetate), PSAFILM (pressure sensitive adhesive), releasefilm (release film) and ProtectiveFilm (protective film).

Polarizer is a kind of lens that can make the light vibrate in a specific direction pass through, and can not make the light in other vibration directions pass through (or the pass rate is very small), the single polarizer looks no different from the general glass lens, all are transparent, but when the two polarizers are stacked perpendicular to each other according to their polarization direction, it will be found that it becomes opaque, and the polarizer can be mainly used for liquid crystal screen imaging.

Transverse waves are allowed to pass through directionally, and there is basically no effect on longitudinal waves. The inner and outer membranes of liquid crystal screens and calculator screens are polarizers.

Countless non-coincident straight lines can be made at one point on the paper, which is a schematic diagram of the vibration direction of ordinary light waves. Polarizers are generally very thin slits that allow only light that is parallel to it in the direction of polarization to pass through. The polarizer filters out light in other polarization directions, resulting in the desired single polarization direction.

It's just filtering some light, it's simple enough.

The display principle of the partial digging reed sheet:

The principle of polarizer is that the display screen of thousands of liquid crystal spheres can convert natural light into linear polarization components, and use the light points in each light point group above to independently be responsible for the display of the selected color and the brightness of the light, in which the function of the performance is to separate the incident linear light with the component of polarization, one part of which is to make it pass, and the other part is to absorb, reflect, scatter and other effects to make it hidden, so that the color separation decompression control image caution effect.

Applications of polarizers:

Polarized lenses are recognized worldwide as the most suitable lenses for driving, with a special function to effectively eliminate glare, allowing drivers to improve their vision and increase driving pleasure. It is also used in liquid crystal displays and 3D spectacle lenses.

Light waves can be selectively transmitted or blocked in specific directions. They change the properties of light by adjusting the direction of its vibration. Polarizers are commonly used in devices such as sunglasses, photographic filters, and liquid crystal displays.

The main functions of polarizers are:

Reduces reflections and flashes: Polarizers filter out light from parallel directions, reducing reflections and flashes and improving the clarity of the field of view.

Reduces eye strain: In strong sunlight, polarizers can reduce the sensitivity of the eyes to harsh light rays, making vision more comfortable and reducing eye fatigue.

Improved contrast: Polarizers can eliminate or reduce light from a specific direction, enhancing contrast and making the contours of objects sharper.

In summary, polarizers can improve visual performance, improve comfort, and provide a better visual experience during outdoor activities and high-light environments.

The display principle of the polarizer: the principle of the polarizer is that the display screen of thousands of liquid crystal spheres can convert the natural light into a linear polarization element, and use the light points in each light point group above to independently be responsible for the display of the selected color and the brightness of the light, in which the function of the performance is to separate the incident linear light with the components of polarization, one part of which is to make it pass, and the other part is to absorb, reflect, scatter and other functions to make it hidden, so that the color separation decompression control image effect. The polarizer display screen must have filters, polarizers, glass, cold cathode fluorescent lamps, and its brightness must be controlled by the IC and component signals in the circuit before it can be displayed.

If the picture does not have the absorption, reflection and scattering effect of the polarizer, then the picture cannot be displayed.

The polarizer is made according to the principle of polarization of light, and the main function of polarization is to effectively eliminate and filter out the scattered light in the beam, so that the light can be put into the glasses visual stimulation pants image on the correct transmittance axis, so that the field of vision is clear and natural, and the non-polarizer is easy to puncture the glasses because of the light in summer.

Generally, sunglasses only use the effect of light reduction, because the general lens can not filter light, so it can only reduce the intensity of glare, ultraviolet light, etc., and cannot completely block these harmful rays, so its function is only to reduce the damage to the eyes.

Because polarized sunglasses have the function of polarizing light, they can block all harmful rays without affecting the transmission of visible light, which can truly protect the eyes. In addition to the basic anti-ultraviolet function, polarized sunglasses also have anti-glare, road reflection light, water surface scale light, etc., suitable for driving, fishing, traveling, and daily wear.

The polarizer can effectively filter out glare, scattered light, and refracted light, and only absorb the reflected ante skate light of the object itself, so as to truly present what is seen. It can improve people's vision, reduce eye fatigue, and make the vision clearer, so as to play the role of eye care and eye protection. In addition, the polarizer can also block all ultraviolet rays, so that the eyes are protected from stuffy ultraviolet rays.

Polarizer application: 1. When driving, you will no longer be troubled by many reflections from the sun and the vehicle in front; 2. When fishing, the water waves shine in the sun, but you will not feel uncomfortable at all, but feel comfortable and leisurely; 3. When skiing, you don't have to worry about reflection and ultraviolet rays, you can glide to your heart's content; 4. When it rains, the rain-soaked road traffic signs are clearly presented in front of your eyes; 5. When you are on vacation, let you enjoy the sun, sand and leisure time to the fullest.
