Display You need to choose the display that best suits your need and fits into your budget. A display is considered to be a user's main point of interaction to get things done. And if it doesn't satisfy you, you'll be left sulking. Apple (Retina Display), Sony (BRAVIA), Samsung (Super AMOLED Plus), Nokia (Clear Black) and Microsoft (Clear Type) all use their own display technologies to enhance the viewing experience.
The most prominent tech terminology of 2013 was full-HD displays and everyone, including domestic handset makers, jumped onto the bandwagon to launch their own full-HD phones. A Full High Definition 1920x1080 display has the same pixel resolution as your living room HDTV, but with a 5 inch screen size – that is very impressive!
So how many megapixels do you really need? A megapixel rating tells you how many pixels there are in a photo. If it measures 4,000 by 2,000 pixels, multiply the two numbers to get 8 million, so it's an 8-megapixel photo.
Also, the most megapixels you're likely to need to show your photos at their best on today's electronic displays is 3MP. If you want them to look even greater, you might want to shoot them at 8MP.
For printing, 300 pixels per inch (ppi) is widely accepted to be as sharp as the eye can see for photo prints.
