Optical Bonding promotes LCD clarity in bright environments.

Press Release Summary:




IMO-bond(TM), optical coupling of contrast enhancing cover glass to front polarizer of display, eliminates reflections from rear surface of optical filter and front surface of display system. Process of applying rigid optical filters to electronic displays via refractive index matched optical (IMO) bonding process includes index-matched adhesives that optically couple cover glass or touch screens to display to eliminate reflection and enhances sunlight readability by greater than 90%.

Dontech Introduces IMO-bond(TM) Optical Bonding for LCD Enhancement in Extreme Environments



Doylestown, PA - June 1, 2009 - Dontech, Inc. has developed IMO-bond(TM), a proprietary process of applying rigid optical filters (e.g., contrast enhancing, EMI/RFI shielding, or Therma Klear(TM) transparent heaters) to electronic displays via a refractive index matched optical (IMO) bonding process. IMO-bond(TM) includes a family of durable, index-matched adhesives that optically couple a cover glass or touch screens to the display to eliminate reflection losses.

Most commercial off-the-shelf (COTS) displays are not designed for direct viewing in bright, outdoor conditions. Dontech developed the IMO-bond(TM) process specifically for the enhancement of such displays operating in high ambient light conditions when the amount of light reflected by a display is close to or exceeds the amount of light emitted by the display. At this point, the contrast loss can be close to 100% and will cause "washout" as the display's luminance is exceeded. Employing IMO-bond(TM) optical coupling of a contrast enhancing cover glass to the front polarizer of the display virtually eliminates reflections from the rear surface of the optical filter and the front surface of the display system.

Benefits of IMO-bond(TM) optical coupling include:
  • Enhanced sunlight readability of > 90%
  • Improved display thermal management in high and low temperature environments
  • Greater versatility allowing for over-frame, under-frame, in-frame and rear-surface bonding applications
  • Better impact resistance as well as increased shock and vibration performance
  • Front surface fluid ingress protection
  • Improved display optics used with EMI/RFI shielding filters, touch screens and vandal shields

    Dontech's IMO-bond(TM) process is ideal for enhancing electronic displays that are commonly used in outdoor and high ambient light applications such as GPS and instrumentation systems used in marine, avionic, military, medical, and industrial environments. For pricing details, contact Dontech.
