Coating Anti
Is the "anti-glare" coating applied to LCD monitors something that you can wipe off like on a camera lens?
This question is more in reference to care of LCD monitors. If you use cleaners on the glass screen that are too abrasive is it possible to remove the anti-glare coating, or is the anti-glare coating on the underside of the glass?
My question: Is the "anti-glare" coating applied to LCD monitors something that you can wipe off like on a camera lens?
Anti-Glare coating isn't really a coating at all. It's an extremely thin piece of plastic covering your viewing surface, one side smooth, and the other side a matte finish (microscopically bumpy) to diffuse the light that shines against it. There is no chemical coating on typical LCD monitors.
Many camera lenses have anti-reflective and anti-UV coatings which do, unfortunately wipe off if you're not careful, especially when using a solvent.
However, it is important to be careful while cleaning your LCD monitor with a damp, soft cotton cloth (never paper towels or toilet paper, as the thin outer layer of your monitor will scratch easily). Water is all you need. Never use solvents like glass cleaner because it is not safe for the plastic on your monitor.

An Introduction to Optical Coatings
An Introduction to Optical Coatings
By: R.L. Fielding
Optical coatings are used to manipulate the reflectance and transmittance of an optical component. Typical optical coating examples include: Antireflection Coatings which reduce the amount of light reflected at a given wavelength or wavelength range; Narrow Band Filters which allow only a given window of wavelengths to transmit; and High Reflector Coatings, used in the production of mirrors. More specifically, custom optical lens coatings utilize broadband and v-coat anti-reflection coatings to optimize application results. Broadband custom optical lens coatings work over a large spectral range, typically, Ultraviolet, Visible, or Infrared, to reduce reflectance and increase transmittance, while V-coat custom optical lens coatings work best at a specific wavelength.
Coatings are designed for a specific incident angle of light and for a specific polarization of light such as S-polarized, P-polarized, or random polarization. If a coating is designed for light at a zero degree angle of incidence, but is used with light at a forty-five degree angle of incidence, the coating will not perform at the stated transmission/reflection specifications. Similarly, coatings are generally designed for randomly polarized light so using S- or P-polarized light with a coating designed for randomly polarized light will again fail to produce the stated specifications.
Coatings are created by depositing dielectric and metallic materials such as SiO2, TiO2, or Al, in thin layers that are typically equal in thickness to one-quarter the wavelength of the light used in the application. These thin films alternate between layers of high index of refraction, and low index of refraction, thereby inducing the interference effects needed. Most optics have some form of coating Optical companies are also able to design and apply custom coating solutions.
Below are definitions of common terms used in the optical coatings industry:
Crystal Thickness Control:
The oscillating frequency of a quartz crystal declines from 5 MHz as coating materials are deposited on the crystal. Consequently, the thickness of the coating on the crystal can be calculated by measuring the fall of the crystal's oscillation frequency. The crystal is positioned at the center of the coating chamber and the coating thickness on the crystal is used to calculate the coating thickness on the optics.
Dielectric:
Material exhibiting very high transmission (non-absorption) across many wavelengths - from the UV through Visible wavelengths and into the IR.
Optical Monitoring:
Direct measurement of an optic's reflectance, performed by reflecting light off the optic and measuring the intensity of the reflected light. A similar procedure can be applied to measuring transmittance. For certain applications, the Optical Monitoring technique yields greater precision than crystal thickness control.
Spatter:
Material unintentionally ejected in larger particulate form from the coating material chunk. These particles can become embedded in the substrate as surface defects.
Thin Film:
Any film that produces constructive or destructive interference effects when light is transmitted through or reflected from it.
There are a range of techniques used in the application of optical coatings. The three most common coating application techniques are:
IBS: Ion Beam Sputter. Sputter process in which energetic ions are produced by an ion gun.
PVD: Physical Vapor Deposition. A coating material is heated causing evaporation such that evaporate condenses on the optic, leaving a film. Coating material can be heated by a focused beam of electrons or by heat derived through electrical resistance.
Sputter: Energetic molecules of coating material are created by smashing accelerated ions into a target of coating material. The sputtered material then forms a durable, stable deposit on the optic. The accelerated ions are normally produced from a plasma of inert Argon.
