Display Specification for Automotive Application V5.1

1Preamble This specification reflects the common intention of the Automotive OEM Working Group as a standard to ensure
optimum customer experience and maximum compliance.It is not regarded as a request for quotation.It is
intended to be obtainable for every interested party from the homepage of the German Flat Panel Display Forum
(https://www.displayforum.de) free of charge.

9 2 Optical requirements
9a 2.1 General
10Area of validity All 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
Spherical coordinates(Θ,φ),horizontal and vertical viewing angles(H,V)according to IDMS v1.03,Section
3.6
Viewing 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 ) coordinates

Display brightness at full white picture calibrated to min. 150cd/m² no additional filters allowed. Inspection after switch to black picture (0,0,0) = no visible bright dot allowed.Dark room conditions, see ID 43.
Viewing distance: 40 cm.

Wrong color not allowed 57
Less brightness not allowed 58
No backlight not allowed 59Broken glass not allowed
60Inhomogeneous color of the background inside viewing area ("rainbow coloring")not allowed
61Yellow Border (variation of film thickness from bonding)not allowed
white picture, 1h heat up at +85°C, no visible yellow border - The maximum quantity of
combined minor defects is 8. A minor defect either is a defect that is not likely to reduce materially the usability of the product in the vehicle or is a departure from an established ideal situation but which has little learing on the effective use or operation of
the product. The judgement shall be done at a viewing distance of 40cm and a viewing time of 45s.- The minimum distance between any two minor defects is 5mm.Defects which are not inside the specified limits or dimensions
will be handled as major defects.
