Can the iPhone 4 really offer the perfect display? V.J. | , 10:39 a.m. June 11, 2010 2010-06-11

Apple has unveiled on Monday the new iPhone 4, a new smartphone both in design and features with 78% display size of the recently introduced iPad. Apple's new version of the iPhone comes with a brand new design and a series of innovation in technological advancements.

Among these innovations is the highly acclaimed retina display, meaning that it boast the highest resolution ever incorporated into a smartphone. Other features include a 5 megapixel camera with LED flash, HD video recording, Apple's A4 processor, and a prolonged battery life by 40%.

The retina display availability is under serious debate as specialists claim that the upcoming iPhone 4 does not have that capability while acknowledging that the display is indeed remarkable. Steve Jobs said that the iPhone 4 has a resolution even higher than the retina, a claim that Dr. Raymond Soneria, president of DisplayMate Technology, says it is „just another example of spec exaggeration”.

Dr. Soneria explained why in an email to PC World. Here is what he said:

„1. The resolution of the retina is in angular measure - it's 50 Cycles Per Degree. A cycle is a line pair, which is two pixels, so the angular resolution of the eye is 0.6 arc minutes per pixel.

„2. So if you hold an iPhone at the typical 12 inches from your eyes, that works out to 477 pixels per inch. At 8 inches it's 716 ppi. You have to hold it out 18 inches before it falls to 318 ppi.

„So the iPhone has significantly lower resolution than the retina. It actually needs a resolution significantly higher than the retina in order to deliver an image that appears perfect to the retina.”

Another claim by Steve Jobs was that the display's glass is engineered and was made from the same material used on helicopters and high-speed trains. You might think this is unbreakable. iFix Your i has put the display to the test with a simple experiment.

The smartphone was dropped form a height of 3.5 feet. The third time it break. Not so tough, isn't it?

The iPhone 4 will be available for retail in the US on June 24 and it will be introduced in the UK, Germany, Japan and 18 more countries in July. Apple's marketing campaign was tremendously successful with the introduction of the first iPhone or, more recently, with the iPad. After all, controversy is part of marketing, but will people trust the brand? Will you?
