3 Measurements and evaluations DMS 201 MEASUREMENTS AND EVALUATIONS EOC: variation of luminance, contrast and chromaticity with electrical driving for evaluation of EOTF-characteristics (e. g. threshold-, saturation-voltage, gamma). Transients: luminance versus time for e.g. response time evaluation. Reflectance characteristics under diffuse and directional illumination. Area scan (optional): scanning of display surface area for lateral uniformity evaluation. Customer specific measurements defined with DCS scripting sequences. SOFTWARE DMScontrol for definition and management of single measurements (e. g. angular scan, area scan, electro-optical transfer function (EOTF), cross talk, temporal response, etc.) and measurement sequences, for administration, evaluation and graphical representation of the results. VIPER Visual Performance Evaluation provides a range of versatile evaluation functions, graphical representations of results, and data export capabilities. DCS Device Control System for integration of third party electronic devices e.g. video test-pattern generators into the DMScontrol software. 3
