Question

Outdoor COB LED screen selection. How to choose outdoor COB LED screen?

Answer 1

When choosing an outdoor COB (Chip On Board) LED screen, you need to consider multiple factors to ensure that it meets the special needs of the outdoor environment. The following are some suggestions for outdoor COB LED screen selection:

1. Screen size:

Determine the screen size based on the size of the place of use and the distance of the audience. Large outdoor plazas or stadiums may require larger screens to attract larger audiences, while smaller streets or spaces may need to accommodate smaller screen sizes.

2. Brightness:

Outdoor environments have high requirements on screen brightness because of the need to combat strong sunlight and other ambient light. Choose a COB LED screen with high brightness to ensure clear, bright images during the day and night.

3. Waterproof, dustproof and high temperature resistance:

Outdoor LED screens need to withstand various climatic conditions, including rain, dust and high temperatures. Therefore, when choosing a screen, you should ensure that it has good waterproof, dustproof and high-temperature resistance to ensure its long-term stable operation.

4. Resolution and pixel density:

Choose the appropriate resolution and pixel density based on the needs of the display content. Higher resolutions and pixel densities provide sharper, more detailed images, but also increase cost and power consumption. Make trade-offs based on budget and usage needs.

5. Gray scale:

Choosing the appropriate gray level is very important to improve the layering and detail of the image. The higher the gray level, the better the display effect.

6. Driving mode:

Choose the appropriate driving method according to the expected display effect and budget, including static scanning and dynamic scanning. Static scanning can provide higher brightness and clarity, but consumes more power; dynamic scanning can reduce power consumption while ensuring display effects.

7. Brand and quality:

Choosing a well-known brand and reliable quality COB LED screen can ensure product performance and stability. At the same time, well-known brands usually provide better after-sales service and technical support.

8. Customization requirements:

If you need a special-shaped screen or customized functions, you can communicate with the manufacturer and customize it according to your needs.

9. Budget:

During the selection process, budget factors also need to be considered. Choose the appropriate COB LED screen according to the budget range to avoid unnecessary waste caused by exceeding the budget.

10. On-site inspection and testing:

  Before purchasing, it is recommended to visit the manufacturer or supplier's production base and sample showroom to understand the actual production conditions and display effects of the product. 

At the same time, suppliers can be asked to provide samples for testing to verify the performance and reliability of the product.

To sum up, when choosing an outdoor COB LED screen, you need to consider screen size, brightness, waterproof and dustproof performance, resolution and pixel density, gray scale, driving method, brand and quality, customization needs, budget, on-site inspection and testing, etc. Multiple factors. By comprehensively considering these factors, you can choose the most suitable COB LED screen for outdoor use.

Answer 2

When choosing an outdoor COB LED screen, you need to consider the following key factors to ensure that the selection meets actual needs and environmental conditions:

1. Resolution and pixel density: High resolution and pixel density are key to delivering clear, detailed images. For outdoor displays, it is crucial to choose a screen with sufficient high resolution and pixel density since the viewing distance may be long.

2. Screen size and customizability: Choose the appropriate screen size based on the space requirements of the installation location and the needs of the displayed content. Also, consider whether you need a customizable screen shape to fit a specific layout or space constraints.

3. Brightness: The lighting conditions in outdoor environments are usually strong, so the screen needs to be bright enough to ensure that it can still be clearly seen under direct sunlight. It is usually recommended to choose a screen with a brightness of above 6000 nits.

4. Contrast: High contrast can ensure clear light and dark images and more vivid colors. This is especially important for outdoor displays, where insufficient contrast can cause images to become blurry in bright light.

5. Color reproduction: True and accurate color reproduction is crucial for outdoor displays. Choosing a screen with high color reproduction can ensure that the displayed content is more realistic and vivid.

6. Waterproof level: The outdoor environment is complex and easily affected by rain and moisture. Therefore, choosing a screen with an IP65 or higher waterproof rating ensures that it will still work well in harsh weather conditions.

7. Heat dissipation performance: Since outdoor LED displays need to operate for a long time, good heat dissipation performance is crucial to maintain the stability of the screen and extend its service life. Choosing a screen with good heat dissipation design can ensure normal operation in high temperature environments.

8. Reliability: Outdoor displays need to withstand various complex environmental conditions, so choosing a screen with high reliability and stability can ensure long-term stable operation.

In short, when choosing an outdoor COB LED screen, you need to comprehensively consider factors such as resolution, pixel density, screen size, brightness, contrast, color reproduction, waterproof level, heat dissipation performance and reliability to ensure that the selection meets actual needs and environment condition.
