Hitachi intros 720p Retina Display style phone LCD
Hitachi today rolled out a display that it compared closely to Apple's Retina Display on the iPhone. The 4.5-inch LCD produces an extremely dense 1280x720 (720p) resolution which, at 329 pixels per inch, is exactly as sharp as Apple's 960x640, 3.5-inch screen. At these resolutions, it's close to the limit of what the human eye can see in pixels, Hitachi said.
Also like its Apple counterpart, the screen uses an IPS (in-plane switching) LCD panel that produces much better color and wider viewing angles than many mobile screens, at about 70 percent of the NTSC color gamut and a 160-degree viewing angle from any direction. The screen is about as bright as Apple's at about 500cd/m2 but produces a relatively high 1,100:1 contrast ratio.
The company didn't name clients for the display and won't necessarily make panels for Apple, but it recently said it was in talks with Foxconn, Apple's primary device manufacturer, to expand its business. Hitachi also said it planned to expand its smartphone LCD range and cater to the "small and medium" sizes that include phones and tablets.
