Measuring the optical characteristics of a microdisplay produces challenges to traditional display metrology. When using light-measuring devices to measure scenes having high contrasts or wide color variations, the instruments suffer the effects of veiling glare or lens flare, thereby inaccurately measuring the luminance or color, especially for darker luminances. Projection display systems, an application of microdisplays, can be subject to ambient and reflected light contributions as well. Adequately characterizing the reflection properties of a raw microdisplay can also prove difficult due to the presence of the haze component. Several tools, diagnostics, and methodologies under investigation at NIST will be presented and discussed.
