 Luminance |
Brightness of the luminescent phosphors (the best strongpoint in VFD)
500~1500cd/§³(for home),1500~3500cd/§³(for vehicles)
10,000~30,000cd/§³(for Head Up display)

 |
| Luminous Efficiency |
Ratio of the consumed electrical energy is converted into light energy
In case of Green as the main color for VFD, it has the highest level of efficiency (20 lm/W or higher)
|
|
| Contrast |
Brightness ratio of the luminous (display)/ non-luminous part
Directly related to readability
As for VFD day time readability: relatively high, night time readability: the highest
|
|
| Cd-free |
Phosphors between Yellow~ Red are ZnCdS series type of phosphors containing Cadmium which is environmentally restricted material. Cd-free product applies phosphors (new substance) without containing environmentally regulated (Cd).

|
| CIG |
IC (Driver, for instance) for VFD operation is installed inside the vacuum tube of VFD: convenience for customers and high brightness as a strong point of VFD can be easily realized
