Technology  LED Display
 
 
Definition
  • Light Emitting Diode Display defines as a light-emitting semiconductor which converts current signals to optical electrical source in depicting images.
 
 
Principle
  • LED Display is created by light source of two-lead semiconductor with pn-junction diode. When a voltage is applied, electrons release energy in the form of photons from recombination of electron holes.
 
 
Structure
 
Characteristics
  • LED Display depicts colors from light source corresponding to the energy of the photon determined by the band gap of the semiconductor, which enhances the uniformity of light and conveys high response rate with long lifespan.
 
  Applications : Electric Rice Cooker, Set-Top Box, Water Purifier, Air Purifier, Dehumidifier, Bus terminal, and so forth
