Abstract: A method for driving an electroluminescent lamp to emit light at a brightness set level includes providing a variable bias voltage to the electroluminescent lamp. The variable bias voltage is increased with the duration of the on-time of the electroluminescent lamp. To stabilize the electroluminescent lamp at the brightness set level against aging, a closed loop control of the brightness of the electroluminescent lamp is applied, which is subject to said duration of the on-time the electroluminescent lamp.

Abstract: An electro-optical display includes a graphics controller and an illuminating device for illuminating a display field of the electro-optical display. A plurality of sensors record actual operating data which are delivered to a control unit and compared with setpoint operating data. If the actual operating data deviate from the setpoint operating data, the control unit performs corrective action on the display. Corrective action is performed by regulating the drive current of the illuminating device, and changing the pulse-width modulation of the illuminating device, or by modifying color values in the graphics memory of the graphics controller of the electro-optical display.
