Beschreibung
Zusammenfassung:	The invention relates to an electric device comprising at least one organic diode, wherein said electric device comprises driving means for driving said organic diode in at least a light sensing state and pre-pulse means for applying one or more electrical pulses to said organic diode prior to driving said organic diode in said light sensing state. A positive electric pre-pulse has been observed to improve the light sensitivity of the organic diode, whereas a negative pre-pulse was found to decrease the time that the organic diode is in the light sensing state for accurately measuring or sensing incident light. L'invention concerne un dispositif électrique comportant au moins une diode organique. Ce dispositif électrique comprend des moyens de commande permettant de faire passer ladite diode organique à au moins un état photosensible, et des moyens pré-impulsionnels permettant d'appliquer une ou plusieurs impulsions électriques à ladite diode organique avant de la faire passer audit état photosensible. On a observé qu'une pré-impulsion électrique positive améliorait la photosensibilité de la diode organique et qu'une pré-impulsion négative diminuait le temps pendant lequel la diode organique se trouve à l'état photosensible pour mesurer ou détecter avec précision la lumière incidente.
