A method of optimizing lifetime of an OLED display element and an OLED display element with optimized lifetime for possible use in a tiled display, while maintaining light output are described. It compensates an OLED operating parameter such as supply voltage and/or on-time of the operating current based on at least one environmental factor which affects aging and on at least one operating factor which is indicative of aging, e.g. by determining the brightness of an OLED display element. To optimize the light output, pre-charge of the aged OLED display elements can be optimized. The knowledge of the working temperature of OLED tiles may be used to regulate the cooling and thus the working temperature, thus improving the lifetime of the display. Furthermore the intensity and contrast of the display illumination may be set within predefined limits to reduce the aging.
