Rear-projection televisions are large-screen units often found in home theater systems. Last year, about 5 million rear-projection televisions were sold worldwide, the vast majority of them CRT-based, iSuppli said. Sales of microdisplay-based rear-projection televisions are expected to rise to 3.3 million units by 2006, compared with 2.9 million sets that use CRT technology, according to iSuppli.
