Check out how the HTC One fares against Google's fourth generation Nexus branded smartphone, Nexus 4.

HTC One vs Nexus 4: Display

HTC One features a 4.7in full HD display with resolution measuring 1080 x 1920 pixels giving it a pixel density of 468 pixels per inch (ppi). This is remarkably higher than the pixel density of the high resolution Retina display of Apple's latest iPhone 5 (at 326ppi).

HTC One is wrapped in what is termed as a 'zero-gap aluminium unibody,' which means there are no seams on the phone. The 4.7in screen of HTC One is similar to that of the Galaxy S3 and feels comfortable to use with one hand.

The Nexus 4, like the HTC One, has a 4.7in True HD IPS Plus display with screen resolution and pixel density less than the HTC One, at 768 x 1280 pixels and 320ppi.

The True HD IPS display of Nexus 4 is supported by 'Zerogap Touch technology,' which is designed to deliver clear viewing experience. The Zerogap Touch has an ITO sensor film which is printed on the glass directly while removing the air gap trapped between two elements. The technology reportedly reduces the thickness of the display while offering slim design and sharp viewing experience.
