Usage environment:

Consider the temperature range of the working environment, which should generally be between -20℃ and 50℃.

Pay attention to the humidity, dust and other conditions of the environment to ensure that the display can operate stably in a specific environment.

Display effect:

Choose the appropriate dot pitch and fill factor according to the viewing distance to ensure the clarity and fineness of the image.

Consider factors such as the color reproduction, brightness uniformity and viewing angle of the screen to obtain the best visual experience.

Brand and quality:

Give priority to well-known brands and products with a good reputation, which usually have more reliable quality and after-sales service.

Check the certification of the product, such as whether it has passed the relevant quality certification standards.

Functional requirements:

Choose appropriate functions according to the actual application scenario, such as whether it needs to support touch, interactive operation, etc.

Consider whether additional interfaces or extended functions are needed to meet specific usage requirements.

Price and budget:

On the premise of meeting functional requirements, compare the prices of different brands and models and choose products with high cost performance.

Be careful not to pursue low prices while ignoring product quality and after-sales service.

After-sales service:

Understand the manufacturer's after-sales service policy, including warranty period, maintenance service, etc.

Ensure timely and effective technical support and maintenance services when needed.

In summary, when choosing an LED display, you need to consider multiple factors such as the use environment, display effect, brand and quality, functional requirements, price and budget, and after-sales service. By carefully comparing and weighing these factors, you can choose the LED display product that best suits your needs.
