Some companies like to keep a lid on leaks about their upcoming stuff, but some companies leak like an old tap. LG falls into the latter, with tonnes of little bits of news leaking out of the company ahead of the official launch of the G4 on the 28th.

This time the leak is about the display, which is has had a major upgrade since the G3. The most exciting thing about the new display is that it sticks with LG's IPS LCD, but adds quantum technology to improve colour and brightness.

In the video, posted to YouTube, LG says that the new QHD display is 25% brighter and has a 20% larger colour range. That's thanks to the new technology.

The LG G3 is easily one of the best phones on the market. If LG can get the G4 right, it will be its best seller yet and could give Samsung and others something to worry about.
