Los Angeles - Casio America made its first appearance at this week's E3 2010 by demonstrating its mercury-free Green Slim video projector as a tool for game players looking to get the biggest bang for their buck in big-screen video game play.

The projector was on display in the official gaming lounge at EA Sports/Strikeforce's MMA 2010 Fight at the Nokia Theater.

Casio also used the E3 opportunity to play up its watch line, awarding G-Shock watches to lucky winners throughout the show at the booth.

Casio's Green Slim projector uses a laser and LED hybrid light source, capable of high-brightness projection for use in next-generation projectors.

Developed under the company's "clean and green" concept, the new projectors eliminate the need for mercury bulbs with the production of a long-lasting light source.

Casio's Green Slim projectors weigh 5 pounds, and measure 1.7 inches thin for easy transportability. They target a wide range of applications, from home-theater viewing to digital signage, to interactive game play.
