1. Specifications and Models: The smaller the pixel pitch, the clearer the image, but the higher the price. Factors such as installation location, area, and viewing distance should be considered to ensure the best viewing experience.

2. Resolution: Higher resolution results in clearer display quality, but also a higher price. This is because high-resolution screens require more LED bulbs and finer circuit designs, which increase manufacturing costs. Therefore, when choosing an LED display, it's essential to balance resolution and price according to actual needs and usage scenarios.

3. Brightness and Color: Displays with higher brightness and richer colors can attract more attention and enhance promotional effectiveness, but they also come with a higher price. Achieving high brightness and vibrant colors requires higher quality LED bulbs and more advanced driving technology. Thus, when selecting an LED display, it's important to choose the appropriate brightness and color performance based on the environment and promotional needs.

4. Screen Size: The size of the display directly affects the price. Generally, the larger the size, the higher the cost. This is because larger displays require more LED modules, structural materials, and more complex manufacturing processes, along with higher transportation and installation costs. Therefore, the appropriate size should be chosen based on actual needs and site conditions.

5. LED Module Type: Different types of LED modules (such as DIP, SMD, COB, GOB, etc.) have varying costs and performance. Some modules may offer higher brightness and contrast but could be more expensive.

6. Protection Level: The protection level affects the display's adaptability to external environments, such as waterproofing, dustproofing, and sun protection. Outdoor LED displays with higher protection levels typically come with a higher cost.

7. Display Technology: Different display technologies, such as DIP (dual-color), SMD (tri-color), and full-color, impact costs. Full-color technology is usually more expensive but provides richer colors.

8. Screen Type: The price of LED displays varies significantly based on the type. For instance, new display technologies like Micro LED, Mini LED, transparent LED displays, flexible LED displays, and 3D LED displays are more expensive due to their higher complexity in production.

9. Refresh Rate: A higher refresh rate can improve image quality and reduce flickering, but it also increases the cost. Higher refresh rates are necessary in certain scenarios (e.g., video playback, fast-moving images).

10. Supporting Systems: The supporting systems for an LED display, including system components, playback systems, editing systems, and monitoring systems, also influence the overall price of the LED display.

11. Raw Materials: The quality and cost of raw materials also affect the price of an LED display. High-quality components like LED chips, driver ICs, PCBs, and power supplies are more expensive but offer better performance and longer lifespan.

12. Brand and Manufacturer: Well-known brands and reputable manufacturers typically provide higher quality products, but at a higher price. These brands offer advantages in product quality, technical support, and after-sales service, and their brand reputation directly impacts the price.

13. Delivery Time and Customization Requirements: Custom sizes, shapes, or other special requirements may affect delivery time and price. It's recommended to communicate with suppliers to confirm delivery time and costs, balancing customization needs with costs.
