- W2023508615 abstract "We explore the calibration of a high luminance range, dual-layer, liquid crystal display (LCD) prototype. The operation of the prototype is done by splitting a high luminance resolution image (graylevel > 2<sup>8</sup>) into two 8-bit depth components and sending these images to the two liquid crystal panels stacked over the backlight module. By interpolation of a small set of luminance data gathered using a specialized luminance probe, the look-up table of graylevel pairs of front/back layer LCD and the corresponding luminance values can be generated. To display images, we fit an extended DICOM model to the interpolated luminance table which is adjustable for graylevel and luminance depth. A dynamic look up table is generated in which for each luminance there are several graylevel pair candidates. We show results for one possible calibration strategy involving the pair selection criterion. By selecting the pair that maximizes back-layer smoothness, the images with arbitrary graylevel and luminance depth can be then displayed with equal perceptual distance between luminance levels, while minimizing parallax effects. Other possible strategies that minimize glare and noise are also described. The results can be used for high luminance range display performance characterization and for the evaluation of its clinical significance." @default.
