Convert Smartphone into Laptop and Projector Using LightPad

qp-logoQP Optoelectronics announced its novel LightPad product at the CES 2012 exhibition in Las Vegas.

The patent pending LightPad technology is an ideal companion device to extend the functionality and user interface of smartphones, providing the user with expanded utility via built-in 11” high contrast rear projection screen, up to 60” screen in front projection mode, and a full-size keyboard.

Connected with a smartphone, The LightPad provides virtually all functions of a notebook computer for an individual. This is mainly thanks to a rebirth of rear projection using a pico-projector. The high gain and high contrast rear projection screen provides for a high quality display. Advantages of using a pico-projector for the display is power efficiency (over 500 nits for under 2.5 Watts), thin form factor and light weight – key factors for a portable accessory device.

[advt]Notebook sized displays are not sufficient for many applications including small group meetings where PowerPoint presentations are common. LightPad can produce up to 60 inch display in front projection mode with its super short focal length projection lens. It can be used as a big screen display/projector for meeting presentations, video/TV viewing, and big screen gaming.

Connectivity to all smartphone platforms with HDMI or MHL output (iOS, Android, Win, Blackberry) are supported.
