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 using 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. The 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.
