As Apple notes, typical LCDs boast a contrast ratio of 1,000 to 1, meaning a well implemented dual-layer LCD would theoretically yield a contrast ratio of up to 1,000,000 to 1.

The whole point of layering two LCD panels was to block light, but the added layer of tracing paper also reduced the intensity of the light so much that it was difficult to produce an actual image.

That's because QD-OLED panels use a different design. Whereas QLED panels put a quantum dot layer atop an LCD light source, QD-OLED TVs use a blue OLED light source with two red and green conversion ...

There are all sorts of acronyms and buzz words on new TVs today, and it can get incredibly confusing, but OLED may be the only acronym you need to know.

Older LCD TVs used cold cathode fluorescent lamps (CCFLs) to provide lighting, whereas modern LED LCD TVs use an array of smaller, more efficient light-emitting diodes (LEDs) to illuminate the screen.

Layers of an LCD screen, including polarizers, transparent electrodes, backlight, etc. If the display is touch-sensitive, there's another bunch of layers that go on top of this as well.
