CRT rear projection.
WHAT IT IS. The most popular choice for giant screens. These are single piece,
self-contained televisions. They typically use three small CRTs—one each for red,
green and blue. The resulting light is projected through a lens and mirror system
behind the screen.
BENEFITS. As in direct view, rear projection CRTs offer superior performance and
moderate cost. With the clever packaging of today's rear projection systems, CRT
rear projectors are not much larger than rear projection systems using LCDs. And
there are no altitude limits.
LIMITATIONS. Can't quite match the viewing angle of direct-view CRT. Requires
periodic convergence adjustment to ensure CRTs remain in alignment and provide a
clear, sharp picture. To make convergence easy, Sony's Flash Focus™ system
performs this alignment in seconds. CRT rear projection can be affected by image
retention and "burn in." Care needs to be taken when selecting aspect ratio and using
videogames to avoid the possibility of image retention due to uneven aging of the
CRTs. And your speakers need to be magnetically shielded, so as not to interfere
with the CRT electron guns.
