As we all know, with the development of society and the improvement of economic level, people pay more and more attention to advertising, and outdoor full-color LED display, as a large screen with high brightness and high-definition display outdoors, can provide people with Commercial advertisements and commercial propaganda media are simple, convenient and more efficient, so full-color LED display screens will inevitably encounter problems of this kind or that in the process of using them. Today, let's take a look at which ones?
Outdoor full color led display
1. Can the indoor LED display be changed to an outdoor one:
1. Brightness limitation: The indoor LED display has low requirements for brightness. The dynamic scanning circuit is mainly used. However, the outdoor LED screen has higher requirements for the brightness because it is a static scanning circuit. The hardware difference between the two is relatively large. Dynamic scanning is mainly to save the hardware cost of the display. The number of driver chips used is more than ten times different, so this also greatly determines the brightness of the indoor screen is relatively low, generally between 1600cd/㎡, which is only suitable for indoors. use.
2. Waterproof restriction: The indoor LED screen structure is basically non-waterproof, even if it is waterproof, it is also a simple waterproof treatment. Outdoor LED screens have high requirements for waterproofing. Because they often encounter wind, rain, thunder and lightning outdoors, Waterproof treatment is done on cables and boxes during production, and the requirements on the box structure itself will be different.
3. Viewing distance limitation: The indoor LED display requires a short viewing distance. The models are generally between P0.9, P1.5, P1.667, P2, P3 and P4, and the area is relatively small and common It is within 100 square meters, and the outdoor LED display requires a longer viewing distance. The model is generally between P8 and P20. Because the outdoor screen is usually larger in area, it generally exceeds 40 square meters.
2. What elements should an outdoor full-color LED display have?
1. High-definition display effect, better presentation of advertising pictures
Outdoor high-definition full-color LED display, as the main carrier of video advertising, needs to have a high-definition display effect. This includes high resolution, high brightness, high contrast, etc. High resolution ensures that high-quality advertising pictures can be presented well; high brightness ensures that the picture can be clearly displayed under direct sunlight; high contrast is the color of the picture. Strong guarantee of uniformity and fine image.
2. Large viewing angle, wide geographical coverage
The main task of outdoor full-color LED display is to do advertising and image promotion. Therefore, letting more audiences see the screen is the primary goal of outdoor high-definition full-color LED display. It adopts a large viewing angle design and covers a large area. Viewing angle.
3. Low energy consumption, energy saving and emission reduction
Outdoor full-color LED displays must respond to government calls, and energy conservation and emission reduction must be implemented as an important standard in manufacturing, including product power consumption, product scattering performance, and the amount of steel required for product installation.

4. High protection level
Generally, outdoor LED display screens have a large installation area and are mostly installed in densely populated places. Therefore, special attention should be paid to the protection level of the display screen, especially in the southeast coastal areas where typhoons are frequently registered. Its design should consider many factors such as the solid foundation of the steel structure, wind load, waterproof, dustproof, moisture-proof and so on. The protection level should be IP65 and above to extend the service life of the display and enhance the reliability.
5. Lightning protection and grounding to prevent leakage accidents
For lightning protection, the LED main body and shell should have good grounding measures, and the grounding form should be considered separately according to whether the display screen is installed independently or attached to the outer wall of the building.
At the same time, the integration of electronic components in outdoor full-color LED displays is high, and its sensitivity to interference is also getting higher and higher. In order to minimize electromagnetic interference, lightning protection devices should usually be installed on displays and buildings.
3. Water treatment plan for outdoor full-color LED display in summer:
1. Use a cloth or towel to absorb a large amount of moisture at a fast speed, and then dry it in the next step, paying attention to the need for power-off operation.
2. After drying the screen, continue to power on and age, the specific operation steps are as follows:
Staged operation: the screen is fully white with 10% brightness, and the power-on aging time is 8-12 hours.
(1) Full white brightness is 30%, time is 12 hours
(2) Full white brightness is 60%, time is 12-24 hours
(3) Full white brightness is 80%, time is 12-24 hours
(4) The full white brightness is..., the time is 8-12 hours
3. There is basically no problem after completing the above steps, but you need to pay attention to the following points during the operation:
(1) Corresponding measures should be taken in time when the screen body enters water, and do not delay.
(2) Quickly dry the water-inflowing screen.
(3) Do not put the flooded screen into the air box, it may cause damage to the LED lamp beads.
