The iPhone 4 has what Apple is calling "Retina Display". What they mean is that the human eye can only see around 300 pixels per inch and they have built the iPhone 4 with 326 pixels per inch. This has the effect of making text and images look smoother and more similar to a high quality printed version.
The retina is the sensitive surface of the eye that acts like the film in a camera. It contains specialized cells called photoreceptors that convert light into electrical signals, which are then transmitted to the brain for visual processing.

Retina display is used by Apple to illustrate the density of the pixels hence the calrity of the screen. Amoled is having different pixel densities and is used mainly by Samsung.
