Our smartphones are mostly made up of screens, at least on the front. That's especially true with today's trend of nearly bezel-less displays. So it's only natural that smartphone makers put a great deal of effort into making and promoting their panels. Take for example the upcoming LG G7 ThinQ and its Super Bright Display, promised to be brighter, denser, but also less power-hungry than its predecessor. And, yes, it's an LCD screen.
