Hitachi Announces Industry's First HD Screen for Mobile Devices
[09/29/2011 11:12 AM]Hitachi Displays this week quietly introduced a 4.5" display for mobile devices that supports 720p (1280*720) resolution amid 329ppi pixel density that approaches the limits of the human eye and which Apple calls Retina screen on its iPhone 4. The new screen will power next-generation smartphones and/or other devices with high-definition displays and with more powerful multimedia capabilities.

The Hitachi 720p 4.5" in-plane switching (IPS) display uses a number of newly developed technologies for high aperture ratio pixels and improved backlight efficiency in LCD displays to prevent the reduced brightness that occurs when designing high-definition displays with superior color reproduction. The panel itself is based on amorphous silicon, whereas earlier high-resolution small displays were based on polycrystalline silicon TFTs that are more expensive and which are harder to produce. Thanks to 329 pixel per inch (ppi) density (0.0257*0.0771mm pixel pitch), the quality of the displayed images will be even a little bit higher than that on the Apple iPhone 4, which has a 3.5" screen with 960*640 resolution with 326ppi density. It is unknown whether the new 4.5" LCD from Hitachi will power a next-generation iPhone, but it is clearly a possibility provided that Hitachi can make a lot of such screens on its production capacities. |
The Hitachi 720p 4.5" IPS LCD display has 16:9 aspect ratio, 55.51mm x 98.69mm display area, 160° viewing angle horizontally and vertically, 500cd/m2 brightness and 1000:1 contrast ratio.
The new HD LCD for smartphones will be exhibited at FPD International 2011 that will be held at the Pacifico Yokohama from October 26 to 28, 2011.
