10Area of validityAll values have to be fulfilled with Cover glass, Touchpanel, LCF - if required - and after white calibration.
Warm-Up Time before measurement: 30 min
Ambient Temp. (if not specified): +25°C
Backlight (if not specified): 100% PWM
All values will be measured perpendicular if there is no viewing angle (area) specified
After lifetime, mentioned in ID 120, all values should fulfill the tolerances given in corresponding IDs 33, 14, 17a
Viewing angle areas for specific applications
Sphericalcoordinates(Θ,φ),horizontalandverticalviewingangles(H,V)accordingtoIDMSv1.03,Section
3.6Viewing angle specific requirements are to be verified by measuring in 5° steps in H and V.Curved borders are transformations of straight borders in ( H, V ) coordinates18aViewing angle areasDisplay Specification for Automotive Application V5.1
