The device also includes at least one dummy pixel having a dummy OLED diode having a cathode to receive the cathode voltage, and an anode, and a dummy control circuit coupled to the anode of the OLED diode and having a power supply terminal. The dummy OLED diode and the dummy control circuit are substantially similar to the OLED diode and the control circuit. First regulation circuitry is configured to deliver a reference current to the power supply terminal to thereby generate a voltage, and second regulation circuitry is configured to regulate the cathode voltage so as to maintain the voltage at the power supply terminal at a given level."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Device with OLED matrix of active pixels with cathode voltage regulation, and corresponding method","description":"A device includes a matrix of active pixels, with each active pixel having an OLED diode having a cathode to receive a cathode voltage, and a control circuit coupled to an anode of the OLED diode.
