When choosing a small-pitch LED display, several key factors need to be considered:
1. Pixel Pitch:
Pixel pitch refers to the distance between adjacent LED pixels, usually measured in millimeters (mm). A smaller pixel pitch results in higher screen resolution, suitable for close-up viewing. The choice of pixel pitch should be based on the usage scenario and viewing distance.
2. Brightness:
The brightness of small-pitch LED displays should be moderate. Excessive brightness may cause eye fatigue, while insufficient brightness can affect display quality. Generally, the brightness of indoor displays is suitable between 800-1200 cd/m².
3. Refresh Rate:
Refresh rate is the number of times the screen updates the image per second, measured in Hertz (Hz). A higher refresh rate reduces screen flicker and improves display stability. This is particularly important in live broadcasts and studio settings where high-speed cameras are used.
4. Gray Level:
Gray level refers to the screen’s ability to display color gradations and subtle details. A higher gray level results in richer colors and more lifelike images. A gray level of 14 bits or higher is generally recommended.
5. Contrast Ratio:
Contrast ratio measures the difference between the darkest and brightest parts of the screen. A higher contrast ratio enhances image depth and clarity, especially important for displaying static images or videos.
6. Viewing Angle:
Viewing angle refers to the effectiveness of the screen when viewed from different angles. Small-pitch LED displays should have a wide viewing angle to ensure consistent brightness and color from various perspectives.
7. Heat Dissipation:
The operating temperature of small-pitch LED displays significantly impacts their lifespan and display quality. Good heat dissipation design effectively reduces temperature, extending the screen’s lifespan.
8. Installation and Maintenance:
Consider the ease of installation and maintenance of the screen. Modular design and front/back maintenance options can affect the user experience and maintenance costs.
9. Signal Transmission:
Ensure the screen supports stable signal transmission, reducing signal delay and loss, and ensuring real-time image synchronization.
10. Brand and Service:
Choosing reputable brands with excellent after-sales service ensures product quality and timely technical support, reducing concerns during use.
By comprehensively considering these factors and selecting the appropriate small-pitch LED display based on actual needs, you can achieve the best display effect and user experience.
