Display
The iPhone 4 CDMA is equipped with a 3.5-inch IPS LCD, which may seem modest by contemporary standards, but offers impressive clarity and brightness owing to its 640 x 960 pixel resolution at about 330 ppi density. This remarkable pixel density, referred to as the Retina Display, set new benchmarks at the time of its release by providing sharp text and vibrant images. This screen size, optimized for the iOS interface, delivers a smooth user experience, from reading emails to watching videos.
