Solar Aging Performance
E3 Displays has developed numerous adhesives that out-perform commercial grade urethane acrylates, epoxies, and silicones in UV aging tests. In an independent side-by-side solar aging test, E3’s proprietary optical adhesive out-performed all other bonding agents regarding color shift and adhesive degradation.
Improved Heat Dissipation
Heat dissipation is the key to measuring display performance. The heat generated by the operation of the display is dissipated through optical material and is not blocked by insulating air layers. By filling the insulating air gap between the components, heat can be transferred to the outside environment.
Shock and Vibration Resistance
Optical Bonding is an effective means of improving resistance to shake and shock environments – a benefit especially useful in harsh military and transportation environments.
Accurate Touch Experience
For optical bonding touch screen monitors, the panel thickness influences touch accuracy and can affect usability with both touch pens and bare hands. An optical bonding touch screen monitor maintains consistently accurate touch response making it easy to use and reliable.
Professional Commercial Grade Options
E3 displays will enhance the best display solution that can withstand the toughest requirements so you can focus on what you do best, providing high quality customer service.
Sunlight Readability
Not only is the glass and bonding adhesive completely transparent to avoid obstructing view-ability and readability of on screen content, but it can also be utilized in all kinds of weather conditions at any time of the day or night. Optical bonding services enables the user to see sharp, clear text and images even with bright sunlight directly on the screen.
Liquid Optical Clear Adhesive
LOCA is used in an optical bonding process where the air gap between the touch display and cover lens is filled. This adhesive is cured using UV light instead of heat. This edge-to-edge bonding process allows for increased viewability, touch sensitivity, and sunlight readability. It increases display durability and prevents moisture from building up between the touch panel and cover lens.
Optically Clear Adhesive
OCA is applied using a process similar to film lamination. Unlike LOCA, OCA is an adhesive sheet that is placed between the touch panel and the cover lens. This adhesive is cured using pressure and heat inside of an autoclave. This method allows for thinner bond lines and is ideal for thinner, more compact applications.
Air Bonding
The process of applying adhesive tape to the edges of a touch panel that allows the cover lens to be bonded to the display. This process leaves an air gap between the touch panel and display cover lens. This process increases glare and reflections while also leaving the display susceptible to moisture and impact damage.
Hybrid bonding
A combination of LOCA and OCA optical bonding. The liquid optically clear adhesive is dispensed to a touch sensor, next to the touch sensor and display are sealed together in a vacuum chamber, then the entire display is cured under UV light. This method of optical bonding provides the same benefits but is used with only certain display applications.
Not “One-size Fits All”
Display models offer a variety of product offerings including transflective displays, super-narrow bezels, to completely bezel-less TFT cells. The market has demanded a wide array of displays, why would you only use one type of adhesive? After careful evaluation of numerous commercial materials (silicones, epoxies, urethane acrylates), E3 Displays determined that while UV curable urethane acrylates offered distinct mechanical and process advantages over silicones and epoxies, these commercially available adhesives did not meet the technical performance criteria essential for use in the harsh environments of avionics and military products. This being the case, E3 displays chose to develop a family of custom adhesive formulations whose overall performance exceeds that of competing materials and are tailored to meet varied product requirements. After thousands of hours of development and testing, E3 Displays has created unparalleled adhesives in optical bonding services which are application (and display) specific.
Value-Added Display Solutions
The E3 Displays adhesives are designed using a low stress, low energy cure cycle which allows great flexibility in designing components and processes to maximize performance in optical bond LCD modules – especially using substrates such as touch screens, ITO, retarder films, and PMMA. Optical materials and components are compatibility tested to assure minimal negative interaction with the adhesive, cure cycle, and display constituents. Customer tests have repeatedly and overwhelmingly verified that the E3 Displays adhesives meet/exceed their specific environmental and optical requirements all while outperforming competitive optical bonding products. Simply put, E3 develops unique, technical solutions that our competitors are just unable to deliver to the same degree. E3 Displays is confident that our optical bonding technology will generate the best value to our customers and ensure the longest possible product reliability. Our clean room manufacturing, ISO 9001 Quality Systems, MIL-spec FDA-level standards, optical and performance testing and small to large scale manufacturing are what separates us from our competitors and why you choose to work with us for your display needs.
