Dontech Introduces IMO-bond™ Optical Bonding
For LCD Enhancement In Extreme Environments
 Dontech, Inc. has developed IMO-bond™, a proprietary process of applying rigid optical filters (e.g., contrast enhancing, EMI/RFI shielding, or Therma Klear™ transparent heaters) to electronic displays via a refractive index matched optical (IMO) bonding process. IMO-bond™ 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™ 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™ 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.
