Home Theater Rear Projection TV

Sony Home theater RPTV

Home Theater Rear Projection TVs have been around for years. Before the advent of newer lightweight DLP and LCD projectors they were Sports Bar staples and were soon incorporated into early Home Theaters. You may want to consider a Home Theater Rear Projection TV for your Home Theater. Depending on the model an RPTV's size and weight may limit its room placement due to the physical footprint of the unit. However their rear projection traits enable them to be placed in rooms with normal lighting conditions. They come in many varieties, shapes and sizes - conventional CRT, DLP, LCD and the newest SXRD models.



CRT Rear Projection TVs - Classic Technology
CRT tube models were the earliest models of big-screen TVs. Sports Bars were among the first venues to use the large units to display the Big Game to their patrons. Sony med Rear projection TV The earliest Home Theater enthusiasts soon found they were ideal to get a bigger picture for their Home Theater. The early units were large and extremely heavy. Also - they often needed calibration in order to keep a decent picture. Modern models are now lighter in weight but still require a couple of moderately strong individuals to relocate. Also - due to the size of their internal three-tube projection device - they are still physically the largest of the Home Theater rear projection TV varieties.

Today's CRT units are much more reliable with regards to image stability due to improved convergence circuitry. Nowadays electronic image alignment can easily be done by most home users if and when it's needed. Also the contrast levels of a CRT are unmatched by any other type of RPTV - although DLPs contrast specifications are approaching those of CRTs. Good used RPTVs are available in the 4x3 format - however most newer models are in the widescreen 16x9 format. Combined with more stable imagery, CRT units have become relatively trouble-free and if you have the required available space, one just may be right for your Home Theater.

LCD Home Theater Rear Projection TVs - Lighter and Brighter
LCD powered RPTVs are lighter and brighter that their CRT predecessors. Due to the smaller size of the LCD panels which produce and project the image - their physical footprint is also considerably less than CRT models. Many LCD units are less than 20" in depth.

LCD RPTV image quality is impressive and has quite true color reproduction. Contrast ratios are somewhat less than CRT and DLP models with blacks not quite equal to that of DLPs but still very acceptable.

Nearly all currently manufactured LCD models are in the wide-screen HDTV format aspect ratio. Therefore if you should choose an LCD equipped Home Theater Rear Projection TV you should also be prepared to invest in HDTV programming sources.

DLP Home Theater Rear Projection TVs - The Best RPTV Solution
As with front firing Video Projectors - DLP technology powered RPTVs are the best in my humble opinion. DLP RPTVs are nearly identical in size and weight to their LCD cousins. The DLP advantage arises from the increased contrast levels and greater fill ratio characteristics of the DLP optical engine. RCA Scenium LCD RPTV I recall seeing my first DLP RPTV - an RCA Scenium model - at a local electronics showroom. Barely 15" deep - it was VERY slim and the image was absolutely astounding. The color depth and detail levels were amazing . I recall looking behind the set several times wondering where the rest of the electronics were - it was that slim. As you can tell I was extremely impressed by the DLP unit and continue to be wowed when I see one. If you can - go to a local electronics retailer to see one. Believe me - you will be impressed.

As with LCD powered Home Theater Rear Projection TVs - DLP RPTVs are mostly tailored to the HDTV format. Therefore if you choose a DLP model you should be prepared with HDTV or widescreen programming. An added advantage of DLP technology is that if you do decide to view SD or 4x3 aspect ratio programming - you can do so without fear of burn-in on your screen. Since the image from a DLP RPTV is produced with mirrors rather than an LCD panel or CRT tube - burn in is a physical impossibility.

Sony's SXRD technology for rear projection TVs was great for a while... until they discontinued it. There is an archived section dedicated to SXRDs near the bottom of the Video Displays page of HTSA. Please refer to this page for information on Sony's formerly ground-breaking technology.

Summing up - a relatively lightweight, small physical footprint, excellent contrast and color reproduction and no fear of image burn-in while viewing standard definition 4x3 programming make a DLP the logical choice of RPTVs.
