It is always annoying when you discover a dead pixel on your prized LCD or plasma television, once you know it’s there you can’t avoid noticing it every time you watch TV. Even if the television is under warranty some manufacturers will not supply a replacement unless more than a specific number of pixels are faulty.
PixelProtector™ Software to fix a stuck pixel
This software called PixelProtector™ claims to fix stuck pixels, reduce screen burn-in and improve the quality of images displayed on a screen. This is achieved by subjecting the stuck pixels to rapid and repetitive changes in brightness from full on to completely off. The manufacturers claim that “most stuck pixels are repaired within 20 minutes”
There are also a range of videos that rapidly switch pixels on and off these are suitable for use on all popular video formats. There are also versions available for the Apple Ipod a range of mobile phones and a version that can be burnt to DVD that will play on loop in a DVD player.
Some screens come with a leaflet stating how many dead pixels they are allowed to have before you can send them back to the manufacturer. Dead pixels may tend to occur in clusters; in most cases displays with such a problem can be sent back to the manufacturer.” Wikipedia
A stuck pixel will usually be most visible against a black background, where it will appear red, green, blue, cyan, magenta, or yellow, although stuck red, green, or blue pixels are most common. Each pixel on an LCD monitor is composed of three sub-pixels (one red, one green, and one blue) which produce the visible colour of the pixel by their relative brightness. A stuck pixel results from a manufacturing defect, which leaves one or more of these sub-pixels permanently turned on or off. wikipedia
Stuck versus dead pixels
Stuck pixels are often incorrectly referred to as dead pixels, which have a similar appearance. In a dead pixel, all three sub-pixels are permanently off, producing a permanently black pixel. Dead pixels can result from similar manufacturing anomalies as stuck pixels, but may also occur from a non-functioning transistor resulting in complete lack of power to the pixel. Dead pixels are much less likely to correct themselves over time or be repaired through any of several popular methods. wikipedia
