Question

What should you pay attention to when choosing an American COB LED display screen?

Answer 1

When choosing an American COB (Chip on Board) LED display, you need to pay attention to the following key things:

1. Quality and brand:

    - Choose well-known brands and reputable suppliers to ensure product quality and after-sales service.

    - Understand the product's manufacturing standards and quality control processes to ensure the reliability and stability of the display.

2. Technical specifications:

    - Resolution and pixel density: Choose the appropriate resolution and pixel density according to application needs to obtain clear image effects.

    - Screen size and customizability: Choose the appropriate screen size based on the installation space and usage scenarios, and consider whether you need a customizable screen shape.

    - Brightness and Contrast: Ensure the display has sufficient brightness and contrast to adapt to different viewing environments and light conditions.

    - Refresh rate: A high refresh rate ensures smooth images and reduces motion blur and smearing.

3. Durability and environmental adaptability:

    - Waterproof and dustproof: The display should have good waterproof and dustproof properties to cope with harsh outdoor environments.

    - High and low temperature resistance: Ensure that the display can work properly under extreme temperature conditions.

    - Lightning protection and anti-static: In areas where lightning is frequent, the display screen should be equipped with a lightning protection device; at the same time, the display screen should have good anti-static properties to prevent static electricity damage.

4. Installation and maintenance:

    - Installation method: Choose the appropriate installation method (such as wall hanging, ceiling mounting, etc.) according to the usage scenario, and ensure that the installation is firm and reliable.

    - Maintenance cost: Understand the maintenance cost of the display screen, the replacement cycle and price of wearing parts, etc., so that you can budget and plan for subsequent use.

    - After-sales service: Choose a supplier that provides comprehensive after-sales service to ensure that problems can be solved promptly and effectively when they arise.

5. Compatibility and scalability:

    - Compatibility: Ensure that the display screen has good compatibility with control systems, playback software and other equipment to achieve seamless docking and efficient operation.

    - Scalability: Consider possible future demand changes and technology upgrades, and choose display products with scalability so that they can be upgraded and expanded when needed.

6. Cost and performance-price ratio:

    - On the premise of meeting the needs of use, comprehensively consider the price, performance, quality and other factors of the product to select cost-effective COB LED display products.

7. Viewing distance and viewing angle:

    - Select the appropriate point spacing (P value) and viewing angle according to the actual viewing distance and viewing angle to obtain the best visual experience.

8. Energy saving and environmental protection:

    - Pay attention to the energy efficiency level and environmental certification of products, and choose energy-saving and environmentally friendly display products to reduce energy consumption and environmental pollution.

In short, when choosing an American COB LED display, you need to consider multiple factors to ensure that you purchase products that meet your needs, have reliable quality, and are cost-effective.
