Graphic screen: according to the content of the display to determine; video screen: generally 4:3 or close to 4:3; the ideal ratio of 16:9. according to the size of the site and aesthetics to do, if it is a wall depends on the location of your wall and staircase size ratio, try to go to do big, even if the resolution to do a little lower try to choose the area of big.

According to the technical point of view to consider, the curtain wall led display in the country are basically square, a little uniform, I recommend to do some creative can attract people's shape. For example, the cylindrical rows, folded corners (such as Shijiazhuang Wanxiang Tiancheng led display), the surprising design will attract more people's attention!

Outdoor LED display size design factors to consider:

(1) The need for display content;

(2) Site space conditions;

(3) Display unit template size (indoor screen) or pixel size (outdoor screen).

Outdoor screen design and installation should be considered factors:

(1) The display screen is installed outdoors, often sun and rain, wind and dust cover, the working environment is harsh. Wet electronic equipment or serious moisture will cause short-circuit or even fire, triggering malfunction or even fire, resulting in losses;

(2) The display may be attacked by strong electricity and magnetism caused by lightning;

(3) The ambient temperature varies greatly. Display work itself to produce a certain amount of heat, if the ambient temperature is too high and poor heat dissipation, integrated circuits may not work properly, or even burned, so that the display system can not work properly;

(4) The audience is wide, the sight distance requirement is far, the field of view requirement is wide; The ambient light changes greatly, especially may be subjected to direct sunlight.

For the above special requirements, the outdoor display screen must do:

(1) The screen and the combination of the screen and the building must be strictly waterproof and leak-proof; the screen should have good drainage measures so that water can be discharged smoothly in case of accumulation;

(2) Install lightning protection devices on the display and the building. The main body and shell of the display screen to maintain good grounding, grounding resistance of less than 3 ohms, so that lightning caused by large currents in a timely manner;

(3) Install ventilation equipment to cool down the internal temperature of the screen body between -10 ℃ and 40 ℃. Installation of axial fans behind the screen above, discharging heat;

(4) Select industrial-grade integrated circuit chips with operating temperatures between -40℃ and 80℃ to prevent the display from not starting up due to low temperatures in winter.

(5) In order to ensure that the ambient light is strong in the case of long-distance visualization, it is necessary to use ultra-high brightness light-emitting diodes;

(6) The display medium uses a new type of wide-viewing angle tube, with a wide viewing angle, pure color, consistent and coordinated, and a life span of more than 100,000 hours.
