Contrast and Brightness Enhancement

Improved readability in environments ranging from High Ambient Light Rooms to Full Sunlight Conditions

Dontech designs and produces optical display components to increase the readability of the information on electronic displays such as LCDs and OLEDs. This is accomplished through contrast enhancement, which includes reducing or eliminating unwanted reflections and, in the case of LCDs, brightness enhancements. High ambient lighting contrast enhancement applications range from something as basic as allowing a patient monitor to be readable in a bright operating room environment to the very demanding sunlight readability requirements of a military avionic cockpit display.

Dontech technologies for contrast and brightness enhancements for high ambient/sunlight readability include the following options:


Solutions incorporating contrast enhancement along with EMI/RFI Shielding and/or Transparent Heating design elements are available.
