Question 1

What is the Samsung Panel Lottery?

Accepted Answer

Samsung sources OLED panels from two manufacturers for the same model: their own QD-OLED panels and LG Display's WOLED panels. Since Samsung doesn't disclose which panel type is in each unit, buyers essentially enter a lottery.

Question 2

What's the difference between QD-OLED and WOLED?

Accepted Answer

QD-OLED uses blue OLED with quantum dots for higher color volume and brightness. WOLED uses white OLED with color filters, which may have lower color saturation in HDR highlights.

Question 3

Which Samsung sizes are guaranteed WOLED?

Accepted Answer

Samsung Display does not manufacture QD-OLED panels in 42 inch, 48 inch, or 83 inch sizes. Any S90D in these sizes is 100% guaranteed to have an LG Display WOLED panel.

Question 4

How do I check my Samsung S90D panel type?

Accepted Answer

You can check your panel type by: 1) Entering your model suffix (FXZA for QD-OLED in North America), 2) Accessing the service menu and checking Ana Peak values (512/588/682 indicate QD-OLED), or 3) Using macro photography to examine sub-pixel structure (triangular = QD-OLED, stripe = WOLED).
