PRODUCT INFORMATION (Image Retention Free) What is Image Retention ? Image retention may not occur when a LCD panel is operated under normal conditions. Normal conditions are defined as continuously changing video patterns. When the LCD panel is operated for a long time with a fixed pattern (over 12 hours), there may be slight difference in voltage between electrodes that work the liquid crystal (LC) in a pixel. The voltage difference between electrodes increases with time, forcing the liquid crystal to lean. When this occurs, the previous image may be seen when the pattern is changed. To prevent this, the accumulated voltage difference must be decreased. Power Off, Screen Saver, or Power Save Mode z Turn the power off for 4 hours after 20 hours in use z Turn the power off for 2 hours after 12 hours in use z Set the Monitor to power off with the PC Display Properties Power Scheme. z Use a Screen saver if possible - Screen saver in one color or a moving image is recommended. Change the Color Information periodically Use Two different colors Rotate the Color Information with 2 different colors every 30 minutes. z Avoid using a combination of characters and background color with large difference in luminance. Avoid using Grey colors, which can cause Image retention easily. Avoid: Colors with big difference in luminance (Black & White, Grey) Change the characters color periodically

PRODUCT INFORMATION (Image Retention Free)
What is Image Retention ?
Image retention may not occur when a LCD panel is operated under normal conditions.
Normal conditions are defined as continuously changing video patterns. When the LCD panel is operated
for a long time with a fixed pattern (over 12 hours), there may be slight difference in voltage between
electrodes that work the liquid crystal (LC) in a pixel. The voltage difference between electrodes
increases with time, forcing the liquid crystal to lean. When this occurs,
the previous image may be seen when the pattern is changed. To prevent this, the accumulated voltage
difference must be decreased.
Power Off, Screen Saver, or Power Save Mode
Turn the power off for 4 hours after 20 hours in use
Turn the power off for 2 hours after 12 hours in use
Set the Monitor to power off with the PC Display Properties Power Scheme.
Use a Screen saver if possible
- Screen saver in one color or a moving image is recommended.
Change the Color Information periodically
Use Two different colors
Rotate the Color Information with 2 different colors every 30 minutes.
Avoid using a combination of characters and background color with large difference in luminance.
Avoid using Grey colors, which can cause Image retention easily.
Avoid: Colors with big difference in luminance (Black & White, Grey)
Change the characters color periodically
