LES (Light Emitting Sensor) technology

Light Emittin Sensor

It is a Polymer based sensor that emits light when fingerprint is contacted.

It is designed for demanding environments where users are exposed to bright sunlight, dusty, dirty and dry conditions.

There is also a function of fake fingerprint detection technology.

What is light emitting sensor?

It is polymer based sensor that emits light through the ridges of the finger when a live finger is contacted.

What is light emiting sensor

Emitting Theory

  • Electric field is generated when a finger is contacted.
  • Electrons on trap level in the luminescent layer will gain the energy.
  • These electrons repeat movement and it makes lights.
