It's easy to visualize the operation of a CRT projector: three tubes, each operating much as the picture tube in the TV on your kitchen counter, flashing overlapping red, green, and blue analog images onto the screen. If you have a good model in top operating condition, and if you or your installer have slaved over its setup, you'll see an incredible picture—one that, on a home-size screen (not so large as to accentuate a CRT's main limitation of light output), is still as good as home video gets.

Sharp has a long history in the home theater projector business. It began with a successful run of LCD models. But the company soon shifted its projectors to Texas Instruments’ DLP technology, which appeared to be ready to dominate the projection business for a time.

However, with the development of new and vastly improved LCD chips and designs in the recent past, all that has changed. LCD (and its second cousin, LCOS—a variation on liquid crystal technology) now dominates the projection market. Sharp is sticking to DLP, and its new XV-Z15000 is one of the first DLP designs to sport a new 0.65-inch digital micromirror device (DMD) from Texas Instruments. The DMD is the imaging chip at the heart of the DLP system.

When 1080p home theater projectors were introduced a year or so ago, a funny thing happened on the way to the party.

Sharp showed off every size and model of its current line.
