What are the common problems of indoor LED display?

  1. Can the indoor LED display be changed to an outdoor one:

  1. Brightness limitation: indoor LED display has low requirements for brightness, mainly using dynamic scanning circuit, but outdoor LED screen has higher requirements for 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 differs by more than ten times, so this also greatly determines that the brightness of the indoor LED display is relatively low, generally between 1600cd/. Suitable for indoor use.

  2. Waterproof restriction: The structure of indoor LED display is basically not waterproof, even if it is waterproof, it is also a simple waterproof treatment. Outdoor LED display has high requirements for waterproofing, because it often encounters wind, rain, thunder and lightning outdoors, so During production, the cables and boxes are waterproofed, 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 P0.8, P1.5, P1.75, 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 outdoor and indoor 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, requires high-definition display effects. 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 indoor LED display is to do advertising and image publicity. Therefore, letting more audiences see the screen is the primary goal of outdoor high-definition indoor LED display. It adopts a large viewing angle design to cover a wide range of viewing angles. .

  3. Low energy consumption, energy saving and emission reduction

  Outdoor indoor 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, etc., and the protection level should be IP65 and above, to extend the service life of the indoor LED display and enhance the reliability.

  5. Lightning protection 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 the sensitivity requirements for anti-interference are getting higher and higher. In order to minimize electromagnetic interference, lightning protection devices should usually be installed on displays and buildings.
