anti glare coating lcd monitors factory

The biggest challenge to achieving high optical performance in digital TV, advertising and signage is the glare and reflection that occurs when light hits a screen. The solution to this issue is by the incorporation of an AR coating.

The use of an anti reflective coating ensures that advertising displays and television screens are fully visible and digital signage is fully readable in daylight.

This application of an anti reflective coating involves applying a film or coating of a specific thickness to the surface. The film reduces the reflections on the surface by cancelling out a specific wavelength of light as it is reflected back to the consumer.

When a specific wavelength of light passes through the AR coating, some of it is reflected back to the consumer and some of it is reflected at the surface. The thickness of the AR film causes the reflected wavelengths to be reflected so that they cancel each other out.

Using an ITO coating has the additional benefit of protection from damage as they increase resistance to impact damage, protecting the LED screen further.

DIAMOND AR anti reflective coating has similar spectral properties to the DIAMOX + coating and is available on polycarbonate, acrylic and glass substrates. There are a variety of different AR coatings available in the DIAMOND AR range. The most suitable coating can be ascertained to meet our customers needs.

For an uncoated glass component, typically 4% of incident light would be reflected at each surface. When an anti-reflective optical coating is used, reflection can be reduced to less than 0.1%

Resistive touch screens were launched about 20 years ago with a lower cost-benefit and a pressure-sensitive surface to react with various objects such as your finger, glove, pencil or specialist tools. Resistive touch technology remains the popular choice for factory automation. Some drawbacks for resistive touch technology include the need for calibration from time to time, a driver is needed for new installations, and the surface of the resistive touch display has a limited lifetime. The resistive touch technology also suffers from reduced light transmittance in comparison with PCAP, therefore, decreases the sought-after high brightness of the underlying TFT-LCD.

Assured Systems provide 3 different surface coatings for PCAP touch screen computers; Anti-Reflection, Anti-Glare and Anti-Fingerprint. These surface coatings can be utilised in both indoor and outdoor environments by enhancing the optical performance of displays.

A chemical-based surface treatment, otherwise known as a chemical AG process, is applied directly to the glass display surface to form micro asperities and give the glass an anti-glare effect under the likes of sunlight. It does not generate any of the minute flaws or micro-cracks that are characteristic of mechanical AG processes and therefore maintains the high surface strength of the glass.

The other way for AG treatment is manufactured by a controlled acid etching process yielding uniform diffused surfaces for anti-glare. Varying levels of diffusion specified as gloss yield different levels of reduced glare. A lower gloss reading denotes a more diffuse panel. The haze ratio of AG glass used on OGS touch screen products cannot be too high, because high levels of haze would affect LCM transmittance. See below figure to have more understanding of specification categories for anti-glare glass.

An Anti-Reflection (AR) coating is a type of optical coating applied to the surface and other optical elements to reduce reflection by the vacuum evaporation process. In typical imaging systems, this improved efficiency since less light is lost due to reflection. In a complex system such as telescopes and microscopes, the reduction in reflections also improves the contrast of the image by elimination of stray light.

AR produced destructive interference in the beams reflected from the interfaces and constructive interference in the corresponding transmitted beams, which increases the transmittance of glass or transparent substrates, the transmittance of glass is approximately 91%, with single-sided coating the transmittance can increase to 94~95%, if with double-sided coating it can increase transmittance up to 98~99%.

The Anti-Fingerprint coating constructions of the advantages of the preferred embodiments like the user are prevented from being imprinted on the surface, and it remains clean and aesthetically pleasing. AFP coating makes it possible to wipe up smudge on the surface very quickly and also has a tremendous hydrophobic performance and protects AR layers and reduced friction and low surface energy and improves scratch resistance. The hydrophobic performance is evaluated each lot by measuring the contact angle. The AF effect is realized by applying a nano-coating to reduce the optical contrast of fingerprints.

The AFP effect means that fingerprint on the surface cannot be seen at all by the naked eye, or only very slightly. Although the fingerprint is on the surface, it is essentially “invisible.” The colour to be coated under visible and infrared light is transparent. The coating is with characteristics like low coefficient of friction, contact angle >100 degrees. It utilizes a vacuum coating process which is also thinner and more even than spread coating.

Anti-Vandal display protective films work by protecting the glass substrate from damage and can be easily removed and replaced by a new film. This provides a quick on a cost-effective solution for those required to maintain public and private spaces from the damage and visual distortion caused by graffiti and reckless vandalism.

Anti-UV protective films are applied for outdoor Panel PCs which are operating in both outdoor and semi-outdoor applications. Even though that is indirect sunlight for the touch surface, there are still ultraviolet light that can damage the structure of touch and cause OCA film yellowing and aging issues. Anti-UV films also reject up to 97% of infrared light coming from sunlight and insulation up to 60% of the heat keep touch surface and system away from heat issues.

Based off of the RadiForce RX850 and RX650 multi-modality monitors, the new models offer all of the same features, such as a streamlined workflow and exceptional image quality, with the added benefit of anti-reflection (AR) coating, a type of optical coating that greatly reduces the amount of glare caused by ambient lighting.

AR coating offers a more vivid display of images on LCD monitors compared to more commonly used anti-glare (AG) coating. AG coating applies a small, uneven texture to the monitor’s screen that diffuses ambient light in order to reduce glare. However, the light emitted from the monitor’s backlight is also inadvertently affected, causing a loss in image detail and black areas to become washed out.

EIZO’s unique AR coating maintains image sharpness using a method that allows the light originating from the monitor to pass through the screen without being diffused. This method greatly reduces reflections from outside light while ensuring that the monitor continues to display crisp images. AR coating allows medical professionals to see the deeper blacks and subtle details in digital mammography, X-ray, and other high-resolution images with exceptional clarity in multi-modality environments.

Anti-glare or anti-reflective is an additional lens coating designed to improve your clarity of vision. This coating increases the amount of light passing through your lenses by decreasing the light reflecting off their front and rear surfaces.

Due to the way this coating works, anti-glare helps you see more clearly by letting as much as 99% of the light through the lens, rather than it bouncing off.

Yes, anti-glare and anti-reflective are the same thing. You may also hear them being called AG or AR for short. Another industry term for this coating is MAR which is an acronym for Multi-Layered-Anti-Reflective.

No, anti-glare is not the same as a blue light blocking coating. Anti-glare reduces reflections across your lenses whilst blue light blocking diminishes the frequency of light commonly emitted from digital screens; known as HEV (high energy visible) light.

Anti-glare glasses work in several ways. By reducing surface reflections, onlookers can see your eyes more easily improving eye-contact. Anti-glare also lets more light pass through your lenses, thus improving optical clarity, definition and overall performance.

The less light that reflects off your lenses, the easier you can see. This is why uncoated lenses are cheaper and less effective compared to anti-glare equivalents.

Anti-glare takes more time, energy and processes to apply to ophthalmic lenses. But the results provide more premium lenses with greater visual performance.

Anti-glare lens coating often contains hydrophobic and oleophobic properties which repel water and natural oil from your skin. Not only does anti-glare improve visual performance, but it makes your lenses easier to maintain.

Due to their reduced reflections, anti-glare glasses have a habit of highlighting any scratches dirt, oil or grease. Anti-glare glasses are also more costly. Because of this, take extra care of your glasses and clean them more frequently to maintain their cleanliness and performance.

Anti-glare isn’t mandatory, but it vastly improves the performance, experience and aesthetics of your glasses. By reducing lens surface reflections, you can see more clearly and naturally, especially if you require high index (thinned) lenses. Aesthetically, people will also see your eyes more clearly.

If you take pride in your appearance, regularly cleaning your lenses keeps them in good condition and prevents deterioration. With lukewarm water and a microfibre lens cloth, anti-glare coatings make it easier to wipe your lenses clean of any dirt, grime or dust. Better still, this coating makes your glasses look more premium thanks to their purple and green hues.

If you have a strong prescription, you probably require high index lenses. However, these thinner flatter lenses have a habit of creating more reflections. Therefore, investing in anti-reflective or anti-glare coating is a good way to combat this side effect.

If you regularly use a computer or drive at night anti-glare / anti-reflective coating can help alleviate eye strain by reducing distracting reflections. This helps you see more easily using less effort to read your computer screen or focus on the road ahead.

If you use ‘safety’ or mineral glass lenses anti-glare coating mitigates their flatter lens profile. By their nature, polycarbonate, Trivex or glass lenses are more susceptible to surface reflections therefore usually always require AG or AR.

If you take selfies or use social media, AG coating reduces the effects of strong lighting, camera flashes or screens reflecting off your eyeglasses. In photos or videos, people will see your eyes more clearly which improves your social interaction and overall aesthetic.

If you work long hours and wear your glasses full-time, AG coating gives the most natural visual experience and places less strain on your eyes. Compared to uncoated lenses, anti-glare coating lets you see more clearly with minimal visual fatigue.

On average, anti-glare lenses cost 50% more than uncoated equivalents. Opticians charge more for anti-glare as they’re more expensive to manufacture. They do however improve the performance and clarity of your lenses by increasing light transmission.

The best way to clean anti-glare lenses is by immersing your eyeglasses in warm water with a mild concentration of dishwashing detergent. This helps soften stubborn oil or dirt on your lenses which can be wiped clean and dry with a microfibre cloth.

Treated with care, anti-glare coating can last between 2-5. If treated poorly, this coating can quickly wear, get scratched and deteriorate in their performance. To help, additional anti-scratch coatings improve the longevity of your lenses but always try to keep your lenses scratch free.

Anti-glare coating is good for night driving by reducing harsh reflections from car headlights, street lamps and traffic signals across the surface of your spectacle lenses.

For quality and longevity, anti-glare is predominantly applied to lenses prior to purchase. This is because the lens surfaces are in virginal condition, free from scratches and dirt which can impede any post-purchase coatings.

No, anti-glare doesn’t block blue light. Anti-glare is designed to increase the amount of visible light which can pass through your lenses. HEV light (high energy visible) isn’t the same frequency as visible light and will pass through any lens without a blue light protective coating.

The efficacy of blue light protection remains unproven. Our lens lab offers blue light protection as a secondary coating which you may wish to have added to your lenses.

A recognisable indicator of anti-glare coating are blue, purple or green hues on the front-side lens surfaces. If these colours are present, they likely have anti-glare coating. If your lenses reflect the same colour as the light-source, your lenses do not have this coating.

Anti-glare is applied to uncoated lenses in multiple stages of thorough cleaning, rinsing, drying and vacuum deposition technology (VPD). Via electrons, the lenses are coated with thin microscopic layers of various metal oxides, each designed to block different frequencies of light.

Essilor’s range of antiglare lenses are deemed as some of the best on the market. This includes their Crizal Sapphire 360, Crizal Prevencia and Crizal Rock lenses. However, many unbranded anti-glare coatings from local opticians and eye clinics provide comparably sufficient performance.
