1. What is an LED display, and how does it difference from an LCD Screen?
2. What are the key differences between SMD, COB, and MicroLED technologies?
3. What is the difference between “Brightness” and “Nits” in LED displays?
Brightness refers to the human perception of light intensity and is inherently subjective, as it depends on viewing conditions and individual visual sensitivity.
Nits, measured in candela per square meter (cd/m²), provide an objective and standardized measurement of luminance.
In practical applications, outdoor LED displays typically require 5,000–10,000 nits to remain clearly visible under direct sunlight, while indoor retail and corporate displays generally operate within the 600–1,500 nits range to ensure comfortable viewing without visual fatigue.
4. What is pixel pitch, and how do you delect the appropriate pixel pitch?
Pixel pitch refers to the distance (in millimeters) between the centers of two adjacent pixels on an LED display and directly affects resolution. A smaller pixel pitch means higher pixel density and better image clarity. We typically determine the appropriate pixel pitch (dot spacing) based on the optimal viewing distance or the height from the ground. Simply put, for longer viewing distances, a larger pixel pitch display is selected; conversely, for closer viewing distances, a high-definition, smaller pixel pitch display is required. This is why the pixel pitch of outdoor LED displays is generally larger than that of indoor LED screens.
5. What is the difference between refresh rate and resolution?
Resolution - Resolution is the total number of pixels an LED display can show, determining image clarity and detail. It is expressed as horizontal × vertical pixels (e.g., 1920 × 1080).
6. What is LED binning, and why is it important for LED screen quality?
7. How do I choose between indoor and outdoor LED displays?
8. What factors influence the price of an LED display?
9. Which quality factors determine a high-performance LED display?
10. What is the future development direction of LED displays, and qhat emerging applications can be expected?
As LED display manufacturing technology continues to advance, the market is seeing the emergence of clearer fine-pitch LED displays, a greater variety of customized/irregular LED screens, and display systems featuring 3D, 4D, and even XR (Extended Reality) virtual functions. Simultaneously, we can anticipate that with the rapid development of Artificial Intelligence (AI), LED displays incorporating features such as immersive sensing, AI interaction, and even robotic companionship will also become a reality.
