65‐4: Patterned Glass Diffusers (PGDs) for Automotive White LED Backlights

Patterned glass diffusers (PGDs) have been demonstrated to reduce backlight thickness and LED count, and increase luminance when used with an optimal film stack in blue mini‐LED backlights. However, they encounter challenges when used in automotive white LED backlights. We report our PGD solution to...

Description
Summary:Patterned glass diffusers (PGDs) have been demonstrated to reduce backlight thickness and LED count, and increase luminance when used with an optimal film stack in blue mini‐LED backlights. However, they encounter challenges when used in automotive white LED backlights. We report our PGD solution to dimensionally and thermally stable automotive white LED backlight that has an LED pitch of 13 mm.
