AR glass, full name Anti-reflection glass (Anti-reflection glass), also known as transmission-enhancing glass or reflection-reducing glass, is a kind of glass with the surface of the glass specially treated. The following is a detailed introduction of AR glass:
The principle of AR glass is to process the high quality glass on one or both sides, and utilize the interference effect produced by the film layers of different optical materials to eliminate the incident light and reflected light, so as to improve the transmittance rate. Specifically, when light hits the surface of glass or other transparent media, part of the light will be reflected back, causing glare. AR coating, on the other hand, is a special film coated on the surface of the medium, where the light interferes, reducing the reflected light and increasing the transmitted light, thus achieving the effect of anti-glare and increased transmittance. The key lies in the thickness and refractive index of the film. By precisely controlling the thickness and refractive index of the film, it allows phase cancellation interference, that is, the reflected light waves cancel each other out, thus minimizing the intensity of the reflected light. At the same time, the refractive index of the film is also designed so that the transmitted light can pass through the medium more efficiently, increasing the intensity of the transmitted light.
High transmittance: The visible light transmittance of AR glass is very high, with a peak of 99%. In contrast, ordinary glass in the visible light range, its unilateral reflectivity of about 4%, the total spectral reflectivity of about 8%, and AR glass can make the light reflectivity reduced to less than 1%.
Low reflectivity: AR glass has a very low reflectivity, which reduces the effects of glare and stray light, making it clearer to view objects through the glass.
Unchanged angle of view: the angle of view will not become smaller after AR glass is installed.
Beautiful appearance: AR glass surface flatness is far better than coated acrylic, and the larger the size, the more obvious the difference. At the same time, AR glass has a glazed feeling and a more beautiful appearance.
Touch screen with anti-reflection combines anti-reflection technology and touch screen technology, aiming to reduce screen reflection, improve image clarity and visibility, while providing convenient touch operation. The following are some of the main application scenarios of touch screen with anti-reflection:
1. Outdoor electronic devices
In outdoor environments with strong light, such as direct sunlight, traditional touchscreens tend to have reflective problems, resulting in images that are hard to see and difficult to operate. Touch screens with anti-reflective can effectively reduce reflections and improve the visibility of the screen under strong light, making it easy for users to view and operate the device even in the outdoors. These devices are widely used:
Smartphones: Users can clearly view messages, make calls, send text messages, etc. outdoors.
Tablet PCs: provide a smooth multimedia experience in outdoor environments, such as watching videos and browsing the web.
Car navigation device: reduce reflective interference and improve the clarity of navigation information during driving to ensure driving safety.
2. Public Information Inquiry System
In airports, railway stations, hospitals, shopping centers and other public places, touch screen query system with anti-reflective can provide clearer information display, so that users can easily access the required information. For example:
Flight dynamics query: passengers can clearly view flight departure and landing times, gates and other information.
Train timetable query: passengers can easily check the arrival and departure time of the train.
Hospital registration information query: patients can clearly view the registration department, doctor information, queuing and so on.
3. Educational equipment
In the field of education, touch screen with anti-reflective can provide clearer and more vivid image display to improve the teaching effect. For example:
Electronic blackboard: Teachers can write, draw and other operations through the touch screen to achieve a more interactive teaching methods.
Multimedia teaching equipment: display teaching videos, pictures and other multimedia materials to improve students' learning interest and participation.
4. Medical equipment
In medical equipment, touch screen with anti-reflective can provide clearer and more accurate image display, which is convenient for medical personnel to diagnose and monitor. For example:
Monitor: Display patient's vital signs data, such as heart rate, blood pressure, etc.
Ultrasound diagnostic instrument: displays the patient's ultrasound image to help doctors diagnose diseases.
5. Industrial control equipment
In the field of industrial control, touch screen with anti-reflective can provide flexible operation interface, convenient for engineers to control and monitor the equipment. For example:
Automation control system: set parameters, monitor equipment status, etc. through the touch screen.
Human-machine interface: displaying equipment operation status, alarm information, etc., which is convenient for engineers to carry out troubleshooting and diagnosis.
The scene of AR treatment on glass surface mainly depends on the demand of the product and the usage environment. The following are some common scenarios that require AR processing:
High requirements on transmittance: If the end product requires more than 93% transmittance of the glass cover, it basically needs to be plated with AR film in order to meet the requirements.
Presence of strong or direct light: If there is strong or direct light within the environment where the product is used, for example, outdoors, the use of AR glass can reduce the impact of glare and reflected light and improve the observation effect.
Need to improve visual effect: In some products that need to improve visual effect, such as high-end monitors and camera lenses, the use of AR glass can improve the clarity and color saturation of the image.
In summary, AR glass is a kind of glass material with excellent optical performance, widely used in a variety of occasions that need to improve transmittance and reduce reflectivity. When doing AR treatment on the glass surface, it is necessary to choose the appropriate treatment method and parameters according to the needs of the product and the use environment.
