Solaris" PMMA Contrast Filters

Double FiltrationA displays output is greatly affected by ambient light reflections. Contrast filters improve the signal to noise ratios of a display by suppressing internal reflections, creating a display that is easier to read. Contrast filters attenuate the ambient light internal reflections or background luminance by the square of the filters transmittance because the ambient light must pass through the filter twice. Contrast enhancement is thus created by suppressing ambient light reflections more than the displays output that passes the filter once, yielding a darker background. Contrast filters can also modify a displays reflectance curves by eliminating various sections of the emitted spectrum, thus creating a better system and viewing environment compatibility. The filtering process also means that the amount of reflected light from the surface of the display is limited, so that the mechanical components and electronics that lie behind the filter are partly or fully hidden.
