  • Patent number: 11881171
    Abstract: An electronic device including a substrate and a pixel circuit is provided. The substrate includes an active area and a peripheral area. The peripheral area is adjacent to the active area. The pixel circuit is disposed in the active area on the substrate. The pixel circuit includes an amplifier circuit and a tunable element. The amplifier circuit includes a non-inverting input terminal, an inverting input terminal, and an output terminal. The output terminal is electrically connected to the inverting input terminal, so that the amplifier circuit is a negative feedback circuit. The tunable element is electrically connected to the output terminal of the amplifier circuit.

  • Patent number: 11842676
    Abstract: An electronic device is provided. The electronic device includes a detection circuit. The detection circuit includes a programming detection circuit, a light-emitting detection circuit and a determining circuit. The programming detection circuit receives a scan signal, a reset signal and a light-emitting enable signal for a driving circuit of a pixel unit, and provides a first detection signal in a first stage according to the scan signal, the reset signal and the light-emitting enable signal. The light-emitting detection circuit receives the scan signal, the reset signal and the light-emitting enable signal, and provides a second detection signal in a second stage according to the scan signal, the reset signal and the light-emitting enable signal. The determining circuit determines whether to output the light-emitting enable signal to the driving circuit according to the first detection signal and the second detection signal.
