Common outdoor full-color LED display size proportion
Outdoor full-color LED display, how do you determine the size, the size of the common ratio is how much?
This powerful giant color graphic screen gives the following advice: according to content to display;
Video screens: general for 4:3 or close to 4:3;
The ideal ratio of 16:9.
According to the site to do size and beautiful degree, if it is the location of the metope you metope and stairs size proportion, as far as possible to do big, even to a low resolution do try to choose the area is large.
According to the technical point of view to consider, curtain wall led display in the domestic basic it is square, a bit stereotypical, personal advice can do some creative attractive shape.
For example, the cylindrical line, angular, surprisingly design will attract more people's eyes!
The size of the outdoor LED display design factors should be considered: (
The needs of the display content;
The space site condition;
Display unit template size (
Or pixel size (
Outdoor screen design and installation should consider factors: (
Screens installed outdoors, and often, the wind dust cover, poor working conditions.
Electronic equipment is wet or seriously be affected with damp be affected with damp will cause a short circuit or even fire, fault and even fire, loss;
The display may be limited by lightning caused heavy current strong magnetic attack;
The environment temperature changes greatly.
Display itself will generate a certain amount of heat at work, if the environment temperature and heat dissipation, integrated circuit may not work properly, and even destroyed, so that the display system cannot work normally;
At a wide, line-of-sight requirement, vision requires far and wide;
Change of ambient light, and in particular may be direct sunlight.
Special requirements for the above, the outdoor screen: (must do
Screen and screen and building the junction must be strictly waterproof leakage protection;
Screen should have good drainage measures, in the event of water discharge smoothly;
In the lightning protection devices are installed on the screen and buildings.
Display the main body and the shell good grounding, grounding resistance is less than 3 ohm, lightning causes a large current discharge in a timely manner;
Install ventilation cooling equipment, makes the screen body internal temperature in -
Range of 10 ℃ to 40 ℃.
Behind the screen above installed axial flow fan, exhaust heat;
Choose working temperature in -
Between 40 ℃ ~ 80 ℃ industrial-grade integrated circuit chips, prevent winter low temperature display cannot start.
In order to ensure that under the condition of the ambient light strong visual over a long distance, must choose high brightness leds;
Display medium choose new wide-field tube, a broad perspective, color pure, consistent coordinate, life over 100000 hours.
