You might consider the new Hitchi screen as a 4.5-inch Retina Display because it can do 329 pixels per inch. By comparison, the Retina Display on the Apple iPhone 4 does 326 pixels per inch.
The Hitachi Retina Display can also do a 720 x 1280 resolution with an LED backlight. You can also look forward to a 1100:1 contrast ratio and we can look forward to the company starting to make these in October. It will take a while for these to hit the market though, so don’t expect these on retail units until the end of the year at the earliest and probably early 2012 is a more realistic landing zone.
The move comes as screens are becoming a huge way to stand out from the crowd, as Apple is highly touting its screen in commercials. Samsung has its Super AMOLED Plus screens that will be landing with the Galaxy S lineup.
One thing is for sure, we’re heading for a future where our smartphone displays will only get better.
