Quantitative numerical values of LE (cd/W)
| LCD TV (SHARP) 60″ | FSC LCD | |
|---|---|---|
| [A] Luminance (cd/m2) | 450 | 1,050 |
| [B] Power (W/m2) | 230/1.00 (=230) | 1.92/0.0094 (=204) |
| [A]/[B] LE (cd/W) | 1.95 | 5.13 |
According to the Energy Star Program (ESP) version 5.3, the power consumption of LCD TV with 50 inches in the diagonal must be 108W or less. The ESP gives luminance efficiency (LE) = 3.8 (cd/W).
