QD vs phosphors
I had expected QD to be the driver for WCG in future displays. However, it seems FPS phosphors are winning most of the design wins. With white LEDs based on FPS phosphors in the BLU, no QDEF is needed to achieve a WCG, saving money.
QD market penetration remains limited to the very high end. The much, much higher volume consumer displays are using FPS phosphors. SS uses QD in their QLED series but not in their MU series. Sony "Trilumious" WCG technology is based on FPS phosphors.
SS KS8000 (QD) 96% DCI, 74% REC 2020
Sony 900E (FPS) 96% DCI, 72% REC 2020
TCL P series plans to use FPS. When I first learned this I was disappointed. However, seeing that Sony using FPS achieves the same performance as SS with QD, I am encouraged.
