| Video Projector |
A video projector takes a video signal and projects the corresponding image on a projection screen using a lens system. All video projectors use a very bright light to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings. Video projectors are widely used for conference room presentations, classroom training, and home theatre applications. A video projector may also be built into a cabinet with a rear-projection screen (rear-projection TV, or RPTV) to form a single unified display device, now popular for “home theater” applications.
The video projector has long been used as a presentation tool in business and commercial entertainment, as well as in some very high-end home theater systems. However, video projectors are becoming more available and affordable for the average consumer. While most video projectors use either DLP or LCD technology, other technologies are also in use. One example is Sony's VPL-VW100 video projector that employs a variant of LCD, known as SXRD. The VPL-VW100 offers a stunning image at full 1080p (1920x1080) native pixel resolution via 3 SXRD Chips, as well as a maximum contrast ratio of 15,000:1. The HD72 provides true 720p HD performance via its Texas Instruments Dark Chip2. |
