The main technical parameters of LED all-in-one machines revolve around display performance, applicable scenarios, and visual experience. Among these, pixel pitch, brightness, and resolution directly affect image clarity and environmental adaptability.
1. Image Clarity Related
Pixel Pitch: Such as P1.25 or P1.56 specifications. The smaller the pitch, the clearer the image at close range, suitable for scenarios such as conference rooms and shopping malls.
Resolution: For example, 1920×1080. The number of pixels determines the ability to render details. High resolution can display more complex images and text content.
2. Environmental Adaptability Parameters
Brightness: Indoor equipment brightness ranges from 1000-2500 nits, while outdoor brightness requires above 5000 nits to meet visibility in strong light.
Contrast Ratio: A ratio range of 1000:1 to 5000:1. High contrast ratio devices produce more distinct color levels in images with strong contrast between light and dark.
Viewing Angle: Wide viewing angles of 140°-180° horizontally and 120°-160° vertically, ensuring consistent color display for multiple viewers from various angles.
3. Dynamic Display Performance Indicators
Refresh Rate: Generally higher than 1920Hz. High refresh rates reduce ghosting during fast video transitions, suitable for sports events, games, and other scenarios.
Grayscale Level: 8-16bit precision, directly affecting the smoothness of color gradations; higher values result in more natural transitions.
