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.
1/ 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 display is applied to each light-emitting diode, characterized by the fact that it includes the following steps:
2/ Process according to claim 1, in which the light-emitting diodes have multiple anodes, with each individual anode being dedicated for the emission of a separate color, and to which a common setting for illumination in a single color is applied to the light-emitting diodes of a subassembly (2).
3/ Process according to claim 1, in which the light-emitting diodes have multiple anodes, with each individual anode being dedicated for the emission of a separate color, and in which a common setting for simultaneous illumination of all colors is applied to the light-emitting diodes of a subassembly (2).
4/ Process according to claim 1, in which the light-emitting diodes have multiple anodes, with each anode being dedicated for the emission of a separate color, and to which a common setting for simultaneous illumination of no color is applied to the light-emitting diodes of a subassembly (2).
5/ Process according to claim 2, 3 or 4, in which the steps of illumination of the light-emitting diodes of a subassembly and of measurement of the current consumed are sequenced in succession.
6/ Process according to claim 1, in which the alerts are relayed to a central station for the verification of operation of multiple display panels.
7/ Display panel incorporating multiple light-emitting diodes, and equipped with hardware and/or software designed to implement the process in accordance with one of claims 1 to 6.
8/ Display panel in accordance with claim 7, in which the light-emitting diodes are grouped within arrays (2) in which the light-emitting diodes are arranged in a matrix, with the said arrays themselves being arranged in matrix form within blocks (5), and with the said blocks themselves being arranged in matrix form within the panel's framework.
