DuPont™ Direct Bonding technology is ideal for use in display applications that require outdoor viewability and operational functionality in challenging conditions. DuPont™ Direct Bonded displays have demonstrated the ability to withstand impact, vibration, extreme temperatures and humidity without compromising performance.
Traditional coverplates often are not treated with anti-reflective coatings and there is an air-gap between the display and coverplate. This results in multiple surfaces with high reflectivity – as much as 13.5% reflectance.
By bonding the front substrate directly to the display, DuPont™ Direct Bonding eliminates the air gap and increases display contrast ratio by 400% for optimum outdoor viewing.
Ruggedization In addition to improving outdoor readability, DuPont™ Direct Bonding provides significant ruggedization benefits, including:
- 300% increase in impact resistance
- 300% increase in resistance to mechanical shock and vibration
- 300% increase in resistance to scratches, gouges, fluids stains and dirt
- Stable performance and reliability in extreme temperatures
Impact Performance Testing DuPont™ Direct Bonding dramatically improved impact resistance over non-bonded displays in steel ball drop tests on notebook PCs. In fact, a 3.0mm bonded glass increased impact resistance as much as 300%. »More
Vibration Testing Large displacements of the display glass can occur when notebook and tablet PCs are subjected to vibrations, such as those experienced in a car trunk or airplane overhead storage. Maximum displacements – where the rear of the LCD glass comes in contact with the backlight unit – can result in film damage and mura defects.
DuPont™ Direct Bonded coverplates significantly reduced input vibrations over non-bonded coverplates in our vibration testing, which evaluated displacement as the center of display and deflection resulting from Z-axis input accelerations . »More
