How To Avoid Plasma TV Burn-In
If you are familiar with the technology behind the plasma TV, you know that the gas in each pixel receives a charge from a set of electrodes and produces ultraviolet photons. These light particles hit a phosphor coating on the pixel walls. If the same image stays on screen long enough for phosphors will age and they will produce a less intense light and color. The phosphorus is constant light will also burn the screen itself, leaving a ghost of a picture. This burning of the screen, and the remaining image it creates is called burn-in. Older CRT monitors, as well as ATMs, are prone to burn-in. This was the reason behind the invention of screensavers, during a randomly shifting image displayed when the image was constant for a certain period of time helps to prevent burn-in
Burn-in is done in 2 steps: premature phosphor. aging and screen burning. A still picture will create an unchanging electrical current in each plasma pixel. The resulting continuous stream of photons forces the television phosphor to release the same shade of light, and this when maintaining a sufficiently long period, will damage the phosphors’ ability to produce this color light. They will be conditional and will never stop producing a faint shadow of the same color light even when no tax is being sent through the pixel. This affects other images that require a change in pixel color. Screen searing is faint, ghostly image that literally burned into the glass on the screen. During a still image, the screen is bombarded with a specific spectrum of light from the phosphor. Because it is given no time to rest, the screen develops a shadowy copy of the image was frozen on the screen. We often see this in the ATM, when remnants of the main menu remains on screen throughout your transaction.
Now that you have an idea what burn-in is, you should know some ways to prevent it from occurring. The root cause of burn-in is a static image. Most newer model plasma TVs have added features to automatically prevent burn-in. However, owners of older model plasma televisions to be aware of the danger of burn-in and should follow a few simply tips to prolong the life of their TV. You can avoid static images by turning off your plasma TV when you can not see it. Also, you should steer clear of pausing a movie or a video game for an extended period and leave the TV on.
Burn-in is no longer a serious problem with newer plasma televisions thanks to a technology called pixel orbiter. The pixel orbiter subtly shifts static pictures to continuously keep plasma-screen phosphors work. By never resting, there is little chance of burn-in. Create more work for the screen may seem like a bad decision with respect to lifetime of the device, but keeping the phosphors fresh and changing actually helps plasma screen last longer.
