Semi-Transparent Mirror Coatings

LCD MIRRORS ● HOSPITALITY ● SURVEILLANCE ● SECURITY

An emerging trend in hotel, restaurant, and retail displays is the use of aesthetically pleasing high performance Semi-Transparent Mirrors to create a hidden smart display mirror combination. The display unit is located behind the mirror, hidden from view until powered on; projecting a clear and sharp image on command.

The semi-transparent mirror coating is available on low iron soda lime glass for low absorption and on grey glass when a more opaque look is needed; as when hiding TVs, security, and surveillance equipment.

All of the Semi-Transparent Mirrors supplied by Abrisa Technologies have an elegant “silver” reflection that remains stable under wide viewing angles. The optical coating has superior color neutral performance across the visible spectrum, to help maintain the original color of the LCD display image.

Large and small format Semi-Transparent Mirrors from Abrisa Technologies can be screen printed, have any one of many high quality edge treatments applied, be machined to any shape as well as have a host of other feature options applied to fit each unique application requirement.

Selecting Your Semi-Transparent Mirror

Application specific factors determine the right product choice. These include ambient lighting levels relative to display brightness, the need to temper the glass for safety purposes, whether the mirror is to be bonded to a display surface and whether the images to be displayed are highly pixelated or not.

Selection Guidance:

Use 35/65 (R/T) for high ambient lighting; 50/50 (R/T) for medium and 65/35 (R/T) for low ambient lighting
2-sided grey glass (50/20) offers superior ambient light blocking, ideal for when display is in the “off” state to hide the mechanics of the display/equipment that may otherwise be partially visible through the glass.
1-sided coating recommended when optically bonding or laminating, to help reduce ghost imaging.

Spectral Performance

All Semi-Transparent Mirrors supplied by Abrisa Technologies have an elegant “silver” reflection that remains stable under wide viewing angles. With superior color neutral performance across the visible spectrum, the optical coating has limited effect on the true color of the display image.
