Oppo Find 5 review: Oppo-lent screen

Display

Oppo is using a 5" IPS LCD screen for the Find 5, protected by Gorilla Glass 2. The defining feature is the 441ppi pixel density, which is the highest we've seen on a mobile device yet (by some distance too). To achieve this density, the screen has 1080p resolution - 1920 x 1080. Yes that's the same number of pixels most HDTVs have, except this time they fit on a surface about 100 times smaller in size.

Oppo Find 5 has a 5" 1080p screen with 441ppi pixel density

The image on the screen appears very close to the glass, which always looks good and combined with the very high pixel density it gives the impression of high-quality print rather than a screen. Individual pixels meld together and even very tiny text remains smooth. Here's what the screen looks like under a microscope (just about the only way to see pixels).

The difference between the 441ppi screen and a 300+ ppi screens can be seen, though it's not nearly as big as when phones broke the 300ppi barrier.

The IPS tech does its intended job well and gives the screen excellent viewing angles - there's color shift only at extreme angles and contrast loss is only observed when looking from the side and from a 45 degree angle - the IPS screens' typical Achilles heel. Since no one is going to look at their screen from that angle though, the viewing angles are perfect for all purposes practical. The screen has vibrant colors too and very good contrast, with pretty good levels of black.

The screen has fairly low reflectivity, which helps the sunlight legibility.

One last thing - we got a unit from the first batch of Find 5's to be shipped and the screen had a dead pixel. It's almost too small to see, but if you know where to look you'll see a tiny black speck. There are reports of other Find 5's with dead pixels, so we thought a warning is due.
