QLED can refer to the quantum dot tech when used with LEDs. Quantum dot tech is an extra film that uses quantum dots which are inorganic reactive dyes that produce better color when hit by a pure white/blue backlight- better than traditional LEDs which have to use a yellowish light source to activate the pixels. OLED is not "new" just a different form of LED- where the organic diodes can adjust brightness on a per pixel level. LEDs have to use backlight for adjustment, which is why they use full array local dimming (FALD) to increase the number of backlights and decrease the size of the zones to improve control. But it isn't at the pixel level yet- that is farther off.
OLED vs LED vs projectors all have tradeoffs- OLED is better viewing angle, but dimmer overall, especially with HDR content as the TVs specifically adjust the activity of the organic pixels to make sure they don't experience burn in. Since it is organic, one set can be different than the other in terms of its susceptibility to burn in. But they try to mitigate it with active adjustment. HDR content is supposed to get really bright.
LED can get really bright, often brighter than OLEDs, but usually doesn't reach the darkness or viewing angles that OLEDs have. "Wide viewing tech" is a film to disperse the light coming off the TV to improve the angles, and it supposedly works well for the Sony 950G and Samsung Q80 and Q90rs. Q dots are newish tech with LEDs to improve the quality of the color and viewing angles. LG LCDs are generally inferior to the good Sony and Samsung (and TCL) sets because they use IPS panels which cannot get black at all. Current Samsung Q80 and Q90Rs are accepted as being really good, like the Sony x950g. TCLs are also great bang for the buck TVs.
Projectors are different again as they really are shooting for big screen sizes. There are short throw and long throw projectors- you should also check to see if you see rainbows with some projectors (I see it when I move my eyes). Not everyone sees it. Projectors aren't suited for daytime viewing- that is more for movie room viewing. That and sheer size, as you should prepare the room to make it darker, etc. TVs can hit 75 and 85 inches, so consider what room you are filling. If you are going for that size, it is likely just overall easier to do a TV rather than screen and projector and such. If you go bigger, well then you have to go projector.
All the tech now is still a balance between brightness, clarity, darkness, and purpose. I'll get a qdot LED TV likely by TCL because
1) its for a bright-ish TV room- I need some brightness (current TV I think is 540 nits on average).
2) LED TVs fit my budget. OLEDs are too expensive for me in 65 inches.
3) My room isn't big enough to merit a projector
4) I do think about burn in- LG and Sony can mitigate it, but that reduces the overall brightness, and I don't want to be so active with my TV watching. Especially with gaming and sports/baseball and soccer watching.
5) the source of your content is just as important as the TV to display it. Discs are great, 4k streaming is also really good. Don't expect SDR to be fantastic with it- it won't be. Some providers suck at their video quality (the satellite providers /dish and direct TV for example).
