How to understand the concept of video pixels of LED displays

Understanding the Concept of Video Pixels for LED Displays

1. 1.Physical pixels of LED screenThey are hardware light-emitting units composed of RGB lamp beads on LED modules and cabinets, which are fixed hardware parameters of the display itself.
2. 2.Video pixelsVideo pixels refer to the resolution pixels of video/image signals transmitted to the LED screen from controllers, computers or media players.For instance, if an LED screen has 2000×1000 physical pixels, playing a 1920×1080 video means 1920×1080 is its video pixel size.
3. 3.Matching relationship between two types of pixels

• When video pixel resolution is smaller than screen physical pixels: the picture shrinks with black borders around.
• When video pixel resolution is larger than screen physical pixels: partial image edges will be cut off.
• Identical resolution between video pixels and physical pixels delivers complete, sharp image without stretching or blank edges.
