Expressly designed and tested for security and surveillance environments, AG Neovo's patented Anti-Burn-in™ technology tackles LCD monitor burn-in effect, otherwise known as a ghost image on the screen. Burn-in images result in the polarisation of the liquid crystal material contained within the TFT LCD panel. The Anti-Burn-in technology prolongs the lifetime of all AG Neovo monitors and displays featuring this technology to secure user’s investment.
What is LCD Burn In?
LCD Burn In, known as image sticking, image retention, or ghost images, is the phenomenon where images displayed for extended periods (fixed screen images) cause the polarisation of the liquid crystal material contained within the TFT LCD panel. The polarisation of the liquid crystal material causes the image to be “burnt” on display.
Is LCD burn in permanent?
LCD burn in occurs because pixels permanently cannot return to their relaxed state after a static image displayed on the screen over a prolonged period. When a screen keeps displaying a single image, the crystals at those pixels will get a permanent memory, and thus the image will be imprinted onto them permanently. Once it causes screen burn in, there is no recovery in most cases. Because of this, choosing a display or monitor allowing for pixel shift, like AG Neovo’s displays with Anti-Burn-in, can help prevent LCD monitor burn in.
Image Retention vs. LCD Burn In
"Image retention" and “Burn-in” are sometimes used interchangeably, but they are not precisely the same thing. Image retention, in most cases, is temporary and fixable. It appears when an image temporarily "stick" on the screen even if the content changes, but reversible by taking particular measures. Burn-in is a form of image retention but is permanent and virtually impossible to fix. The prolonged use of static images would cause screen burn-in.
How to fix screen burn in?
LCD burn-in is technically hard to fix. Instead, here are some tips on how to remove image persistence on LCD screens and prevent permanent LCD burn in effect:
4 Tips on How to Fix and Prevent LCD Screen Burn In
- Enable “Pixel Shifting” function on your monitor or display. Most of AG Neovo monitors have a built-in Anti-Burn-in, which allows varying pixel usage by activating the pixel to move at regular intervals. If not enabled automatically, you can manually turn it on and try to alleviate any image retention problems.
- Reduce screen contrast and brightness. Lower contrast allows even lighting level across the LCD screen and thus has less strain on a specific area of the screen. Then, try to watch some different contents, and the burn-in effect might go away on its own.
- Turn on white static for approximately as long as the persistent image was displayed; this is to use a completely white screen to overwrite the burn-in image. Or, create a screensaver that alternates between black and white images. The continuous changing of white/black across your screen can help alleviate the ghost image from the screen. The solid colour background might reset the image burn but is more likely to deal with image retention than image burn-in.
- Try playing a colourful video in full-screen mode for a few minutes to half an hour or restart your monitor several times may help.
AG Neovo patented Anti-Burn-in Technology
Anti-Burn-in technology is to activate the pixels to move by the designed time interval and protect panels from being seen the vaguely visible “residual image” under the static charge conditions so as to help prolong the lifetime of TFT LCD panels.
The patent on the Anti-Burn-in technology shows that AG Neovo places importance on its display quality to prevent image burn in. To best fit the requirement of the security environment, Anti-Burn-in Technology is invented with high-level flexibility and effectiveness. There are three types of mode:
Execute faster than the Line and Dot Intervals. Frame Movement is to move the entire video frame horizontally and vertically (right/left/up/down) for a preset time interval.
Slower but more precise than the Frame Movement. Line Movement is to scan the screen starting from top to bottom and left to right with horizontal and vertical moving lines for a preset time interval.
The slowest but the most precise Anti-Burn-in mode. Dot Movement is to scan the screen with a set of “black & white” dots or pixels in left-to-right and top-to-bottom directions.
