| 摘要 |
The invention concerns a light display panel with a matrix of pixels (5) comprising each three monochrome electroluminescent diodes (6, 7, 8) of three colours. The diodes are controlled by a control circuit (9) delivering electrical power P to each diode, said electrical power being expressed in the form P=k.Pr, wherein Pr is a reference electrical power particular to the diodes of each colour and k is a coefficient selected according to the display to be presented. In course of time the reference electrical power is subjected to different variations depending on the colours, to compensate for the ageing of the diodes.
