Working Group “Switchable Privacy” SP(D)

Definition of a specification (that can be used as a guideline) for the topic “Switchable Privacy Display” SP(D) to ensure driver safety. The SP(D) should fulfil in “public mode” the “usual” image quality requirements of the OEM and should maintain this image quality for the co-driver in “private mode”. In “private mode” the driver should not been disrupted or disturbed by the Co-driver display.

The main goal of the described procedures is to define a combination of measurement setup and to characterize relevant measurement values that ensures the reproducibility of the measurements.

Working Group “Full Array Local Dimming” FALD

Definition of a specification (that can be used as a guideline) for the topic “Full Array Local Dimming” (FALD) that provides techniques to characterize different luminance related quality criteria of Full Array Local Dimming Liquid Crystal Displays (LCDs) also called Device under test (DUT) using luminance cameras. This specification covers the following FALD related measurement items.

• Light spread function
• Peak white luminance
• Static halation (Halo mura)
• Local white uniformity
• White uniformity / grid mura

The main goal of the described procedures is to define a combination of measurement setup and evaluation that ensures the reproducibility of the measurements.
