What is the Difference Between Mini LED and Standard LED?

5 views admin 2025-08-01

  • I. Technical Principles
 
  • 1. Standard LED (Traditional LED Backlight):
 
  • • Uses larger LED beads (typically larger than 200-300 microns) as the backlight source for liquid crystal displays (LCDs).
 
  • • The number of backlight zones is small (typically dozens to hundreds), and brightness is controlled through global dimming or local dimming (such as edge-lit or direct-lit).
 
  • • Disadvantages: Fewer zones result in limited contrast, and "halo" or light leakage may occur during dark scenes.
  • 2. Mini LED:
 
  • • Uses smaller LED beads (approximately 100-200 microns), allowing for denser arrangement of more beads within the same display area (tens or even hundreds of times the number of traditional LEDs).
 
  • • The number of backlight zones is significantly increased (up to thousands), enabling finer local dimming (e.g., over 1,000 zones), approaching "pixel-level" light control.
 
  • • Advantages: Higher contrast and brightness, clearer dark details, and significantly reduced light leakage.
 
  • II. Display Comparison
 
  • Regular LED: Low contrast (relies on global dimming)
 
  • Mini LED: Extremely high contrast (zoned dimming improves dark scene performance)
 
  • Regular LED: Peak brightness typically ≤ 1000 nits
 
  • Mini LED: Can reach over 2000 nits (supports HDR)
 
  • Regular LED: Black scene performance may appear grayish and exhibit light leakage
 
  • Mini LED: Nearly pure black with rich detail
 
  • Regular LED: Higher energy consumption (requires full-screen backlighting)
 
  • Mini LED: Lower power consumption (zoned dimming for power saving)
 
  • Regular LED: Longer contrast and lifespan, but with light decay
 
  • Mini LED: Longer (smaller LEDs disperse heat)
 
  • III. Application Scenarios • Regular LED: ◦ Mid- and low-end LCD TVs, monitors, laptops, etc. ◦ Suitable for everyday use on a budget and without extreme image
 
  • quality requirements. • Mini LED: ◦ High-end TVs (such as the Apple Pro Display XDR and Konka A8 Mini AI LED), professional monitors, and gaming monitors. Suitable for movie/game users who pursue HDR effects and high contrast, or professional design fields that require precise colors.
