Hitachi reveals 720p screen for smartphones

Posted on Thursday, September 29 2011 @ 23:23:00 CEST by


X-bit Labs reports Hitachi has crafted a 4.5" IPS screen with a resolution of 1280 x 720 pixels!
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.
