By increasing the aperture ratio of the three 1.3" polysilicon active matrix TFT panels and by upgrading the UHB lamp to 250W, Hitachi has achieved high brightness of 3, 500 ANSI Lumens. As a result, the CP-X990 will project images that are clear and easy to see, even in a bright room. It also uses a new filter that increases contrast to 600: 1 for sharply detailed images. And because Hitachi's proprietary optical design provides superior brightness uniformity, images are bright right to their edges. Even with this high performance, the projector is very light at only 6.5 kg (14 lbs. 5 oz.) and easily portable.
