Abstract:
1. An electronic circuit for interfacing with an OLED device, the OLED device comprising an OLED means including electrodes and an organic light emitting material for generating light, two or more conductive elements for conducting current, and a substrate for mounting the OLED means and the two or more conductive elements, the electronic circuit comprising: a voltage bias means for providing the OLED means with a voltage bias; a radio frequency (RF) voltage means for providing one or more of the conductive elements with an RF voltage; a gain amplifier configured to apply an other voltage bias to one of said electrodes, wherein said other voltage bias reduces a voltage across at least one capacitor formed between the OLED means and at least the one or more of the conductive elements; a current measuring means for measuring a current flow through each of the one or more of the conductive elements; and a signal generating means for generating a signal, wherein the signal depends upon the current flow through the one or more of the conductive elements.
