Current AMLCD flat panels for military applications require intense backlighting to permit readability in full sunlit situations. This intense backlighting consumes a great deal of power, which limits their applications, reduces their reliability, and often necessitates cooling. One major factor aggravating this need for intense backlighting is the poor efficiency of the color filters. Not only have these filters low transmittance, they are not spectrally poor which also results in poor color gamut. Smiths Industries suggests a new version of AMLCDs which does not have these lossy filters, but instead, utilizes a layer of green, red and blue phosphor embedded within the AMLCD. These phosphors are energized by an ultraviolet backlight. This new technology could reduce the power consumption by a factor of four, while maintaining the same display luminance and contrast.
