Abstract
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.
Claims10
Electric device (1) comprising at least one organic diode (3), wherein said electric device comprises:
- driving means (8) for driving said organic diode in at least a light sensing state (S), and
- pre-pulse means (10) for applying one or more electric pulses (Vpre) to said organic diode prior to driving said organic diode in said light sensing state.
Method for driving an organic diode (3) in a light sensing state (S) comprising the steps of:
- applying one or more electric pulses (Vpre) to said organic diode to prepare said diode for a light sensing state (S);
- driving said organic diode in said light sensing state (S).
