Planar ERO-LCD

Improved contrast. Faster perception.

Planar® ERO-LCD™ (Extended Ruggedness and Optics™) technology utilizes a protective glass that is bonded to the front surface of the display using a proprietary process that creates a highly durable display surface that can withstand rigors of high-traffic environments.

This added durability can make any display ideal for usage in interactive applications. Planar ERO-LCD also improves perceived contrast by more than 300 percent, giving viewers the highest quality visual experience, and making content more readable and impactful even in bright public venues.


Improve the Clarity and Durability of Your LCDs

Planar ERO-LCD technology is achieved by optical bonding, which is the process of laminating cover glass or touchscreens to the LCD cell. A bonding agent is inserted between the cover glass and LCD to completely fill the air gap. The assembly is cured in a process that affixes the panels together while solidifying the gel.

Why would someone need ERO?

Protection - LCDs have plastic surfaces that are not vandal or weatherproof. To protect your display investment most LCD installations require a cover glass or polycarbonate lens to protect the LCD.

Clarity & Viewability - Optical bonding eliminates the internal reflection between the LCD and the cover glass or touchscreen because the bonding process creates a single index of refraction. Reducing internally reflected light loss increases display contrast and viewability. Improved display contrast enables displays to be more readily seen in bright ambient conditions, without increasing backlight brightness and the associated unwanted higher power and higher operating temperatures. Shake & Shock Optical bonding is an effective means of improving resistance to shake and shock. This benefit is especially useful for military and transportation applications.

Dust & Moisture - Filling the gap between the protective glass and LCD keeps out dust and moisture. Condensation or dust can make a display unreadable.

Less Parallax Error -
Due to the closeness of the LCD to the glass surface with Planar ERO-LCD, the parallax error is significantly less than that of a display with just glass in front of it.

Modular Protective Touch Surface - Traditionally, other implementations of touch systems for LCD video walls have required a large piece of glass in front of the LCD to protect and provide a touchable surface. This glass can make installation, transport and servicing of large video walls cumbersome. The modular design of the Clarity® Matrix® G3 LCD video wall with Planar ERO-LCD provides a near seamless touch surface while ensuring ease of installation and serviceability.
