Session: Switchable Privacy Displays for Automotive Application

Switchable Privacy Displays with Liquid Crystals and Collimated Backlight: Techniques and Measurements

Invited

Description:

Switchable Privacy Displays (SPD) enhance a wide range of applications, including codriver displays in automobiles. In "private" mode, the driver must not be distracted. SPDs base mainly on liquid crystals and collimated backlights. Angle measurements of different SPDs were performed to extract relevant parameters such as luminance and uniformity. Evaluations with 20 subjects recommend a luminance of <0.1 cd/m² for the driver in private mode at night to avoid distraction.
