Reduce Lens Flare on RPTVs

Lens flare can dramatically decrease the black levels on an RPTV. Learn what lens flare is, and how to knock it out of the equation on your RPTV.

Although one expects CRT-based rear projection televisions to deliver good black levels, there is a factor that compromises black level performance in these displays. This factor is something called lens flare. Lens flare is most commonly seen in photographs. It usually occurs when the photographer is shooting in the general direction of the sun. Bright sunlight enters the lens at an angle and bounces around inside the lens body. As it reflects off of the interior parts of the lens, some of it ends up getting on the film, usually in the form of bright circles or shapes, smears of light, or lines.
