Range of 10 ℃ to 40 ℃.
Behind the screen installed above the axial flow fan exhaust heat;

Increase the contrast.
At a wide, line-of-sight requirement, vision requires far and wide;
Change of ambient light, and in particular may be direct sunlight.
Display medium broad new wide-field tube Angle, color pure, consistent coordinate, life over 100000 hours display medium outside packaging is the most popular belt along the square cylinder, silicone seal, no metal cosmetic;
Its appearance delicate and beautiful, durable, resistant to direct sunlight, dustproof, waterproof, anti high temperature, prevent short circuit five characteristics.
Small make up warm reminder, outdoor LED display installation considerations involved products after use and safety, must be strictly treated seriously.
When installing the outdoor electronic display must be above will be ready at six.
