Paper Abstract

We report on the characterization of two novel probes for measuring display color without contamination from other screen areas or off-normal emissions. The probes are characterized with a scanning slit method and a moving laser and LED arrangement. The tails of the scans indicate the spread in signal due to light from areas outside the intended measuring spot. A dual-laser setup suggests that color purity of the reading can be maintained up to a few tens of millimeters outside of the measurement spot, and a dual-LED setup shows the effects of secondary light emissions in the readings. The first design, color probe A, is then used to quantify display color, maximum color difference, luminance uniformity, graylevel tracking, and angular color shifts of medical liquid crystal displays and mobile displays.
