Example of fan installation
- If the temperature is too high
Electronic component’s
life time will be shortened or break down.
-If the temperature on LCD surface is too high
Monitors will break down or uniformity issue will occur

of video and colored still image, uniformity can’t be
identified.)and view angle under low temperature(around 0℃).
So the note in catalog is as the followings.
“Under 10 ℃, you may see the uniformity issue partially on the
edge of the display depending on the view angle . But this
phenomenon is not breakdown which affects the performance
of this product.”
