METHOD FOR VERIFYING THE OPERATION OF A BILLBOARD HAVING LIGHT-EMITTING DIODES |
| 摘要 |
Process for verifying the operation of a display panel (1) incorporating multiple light-emitting diodes arranged in multiple subassemblies (2), in which a current of an amperage corresponding to a set level for commanding the desired illumination is applied to each light-emitting diode, characterized by the fact that it includes the following 10 steps:
apply a pre-determined common setting to each light-emitting diode subassembly (2);measure the current consumed by each light-emitting diode subassembly (2);determine an average value of the currents consumed by all the subassemblies (2);trigger a malfunction alert for a subassembly (2) when the deviation in absolute value between the current consumed by the said subassembly (2) and the said average value exceeds a previously-determined threshold. |
