Systems and methods of managing metameric effects in narrowband primary display systems

摘要

Several embodiments of display systems that use narrowband emitters are disclosed herein. In one embodiment, a display system comprises, for at least one primary color, a plurality of narrowband emitters distributed around the primary color point. The plurality of narrowband emitters provides a more regular power vs. spectral distribution in a desired band of frequencies.

主权项

1. A method for driving a display system, said display system comprising at least one plurality of narrowband emitters, said at least one plurality of narrowband emitters emitting lights selected in frequency substantially near a first primary color such that said at least one plurality of narrowband emitters emit a substantially even power distribution in a desired band when said at least plurality of narrowband emitters are turned on, the steps of said method for driving a display system comprising:
inputting image data; calculating input image data color saturation values; calculating input image luminance values; and selectively determining which narrowband emitters to turn on, depending upon the calculated saturation and luminance values of the input image data; wherein said step of selectively determining which narrowband emitters to turn on further comprises: selecting an initial set of narrowband emitters to turn on to an initial luminance value, depending upon the color saturation of the input image data; comparing the luminance of said initial set of narrowband emitters to the luminance value of the input image data; driving the initial set of narrowband emitters to a luminance value higher than the initial luminance value, if the sum of the initial luminance value of the initial set of narrowband emitters is lower than the luminance value of the input image data.
