Notably, LCD and OLED transparent displays do not qualify for this market.

Available at retailers: in-stock and purchasable by consumers (B2B-only doesn't qualify). For online purchases, must reportedly be actively shipping.

I'll be pretty permissive about what style of display it is. Could be a full-sized TV, standalone desktop monitor, pre-installed into laptops, used in novelty drinking glasses, or what have you. Notably it needs to actually be a working screen so keep those light up Disneyland mugs in your attic, thanks.
