64‐3: Patterned Glass Diffuser for MiniLED Count Reduction

Abstract

We report our progress on a monitor‐sized, dimensionally and thermally stable mini‐LED backlight enabled by a patterned glass diffuser (PGD). Our backlight uses 5,000+ fewer mini‐LEDs per monitor — 4/9 times that in a reference mini‐LED backlight relying on a thicker diffuser plate, while it is thinner and achieves similar uniformity and luminance compared to the reference mini‐LED backlight.

P‐55: Patterned Glass Diffuser (PGD) for Luminance Increase and with Glass Circuit Board (GCB) in a Mini‐LED Backlight

“…The PGD is also able to reduce the number of the LEDs if the total thickness is fixed or reduced to a less degree, resulting in cost savings associated with the LED cost, LED driving circuit, and the yield of the light board [18].…”

“…We reported the use of a patterned glass diffuser (PGD) in a mini-LED backlight to reduce the total thickness [17] or to reduce the LED count [18] while maintaining the luminance and uniformity. In this paper, we report the use of the PGD to increase the luminance, while reducing the total thickness; and we also report the use of all-in-one (AIO) PGD along with a glass circuit board (GCB) in a mini-LED backlight.…”
