Every time LG comes out with another of these models we get this discussion. This is an IPS LCD screen, not a quantum dot display. Unlike Samsung, LG does not make small form factor OLEDs so they are forced to use these screens. They have been using the term quantum display since at least 2014 for cell phones and some large televisions. It's a marketing gimmick, and no deeper meaning should be inferred.

From a review of this spring's G5:

"LG equipped last year’s G4 with an all new 5.5-inch QHD display. Its IPS Quantum Display moniker was a bit misleading, however, because the panel did not use quantum dot technology or bring about a quantum leap in performance."
