I have to concede your point. I misread the PR. Reading it again right now, it clearly indicates that it's a technology for displays and is ready to move to commercialization with partners, not in ready product.
"Leading American cadmium-free quantum dot and nanomaterials manufacturer Quantum Materials Corp, (OTCQB: QTMM) announced today that it has produced and is demonstrating to select customers a 100% cadmium-free 55 inch QDX™ quantum dot display technology that achieves an industry-leading 95% Rec. 2020 color gamut coverage."
If you are outright questioning the PR because of a picture that's your decision.
I will believe what was actually PR'd and take the more likely scenario that QMC is bound to a NDA with OEMs and therefore is unable to show the display publicly.
