Outline
This system captures images using a CCD camera to measure and analyze the characteristics of LED and brightness distribution in contrast to a conventional luminance meter, which measures only a single point. |

 |
| Characteristics |
 |
Brightness distribution measurement and pass-fail judgment of R, G, B, and IR at each of 30 mA and 0.5 mA |
 |
Measurement and pass-fail judgment of reverse current of the R, G, B, and IR |
 |
Measurement and pass-fail judgment of the R, G, B, and IR |
