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. This technology prolongs the lifetime of all AG Neovo monitors and displays to secure the user’s investment.
LCD Burn-In, known as image sticking, image retention, image persistence 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 screen.
Burn-in on LCD screen occurs because pixels permanently cannot return to their relaxed state after a static image displayed on the screen over a long period of time. When a screen keeps displaying a single image, the crystals at those pixels will get a permanent memory, and thus the image on the screen 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 monitors with Anti-Burn-in, can help prevent LCD computer monitor 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 "stuck" on the screen even if the content changes, but reversible by taking particular measures. Burn-in on the LCD screen 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.
Burn-in on the screen is technically hard to fix. Instead, here are some tips on how to remove image persistence on LCD screens and prevent permanent effect:
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.
