iPhone 4: IPS “Retina Display” Offers Better Experience than OLED Technology
Steve Jobs kicked off WWDC this week by announcing the iPhone 4 with FaceTime video calling capabilities. The phone offers a number of improvements over its predecessors, including the highest resolution screen on a smartphone, IPS display technology for wide viewing angles, and sharp graphics and text. All this adds up to what Jobs called “retina display.” Jobs says that 300 pixels per inch–the standard used in print publishing–offers smooth lines for text and images. With over 300 PPI on the iPhone, images, graphics, and texts will be smooth without any pixelation.
Moreover, Apple went with the “retina display” solution over solutions such as OLED and AMOLED displays because it offers the most crisp display. Coupled with IPS technology, the iPhone can render fonts perfectly, have bright colors that pop, and show details beautifully, which comes in handy with the 5-megapixel camera and HD video recording capabilities of iPhone 4.
