  • Patent number: 11482172
    Abstract: A display device and an operating method of the display device are provided. The display device includes a first light emitting diode (LED), a first switch, a second switch, a second LED, a third switch, and a first controller.

  • Patent number: 10977985
    Abstract: A display device and a driving method thereof are provided. The display device includes a first light-emitting diode, a first controller, a second light-emitting diode, and a second controller. The first controller has a first current source. The second controller has a second current source, wherein the first current source is coupled to a coupling point of the second light-emitting diode and the second current source. When the first light-emitting diode is normal, the first current source provides a first driving current to drive the first light-emitting diode. When the first light-emitting diode is open, the first current source stops providing the first driving current, and the second current source provides a second driving current to drive the second light-emitting diode.

  • Patent number: 10861382
    Abstract: A pixel circuit includes a first lighting circuit, a second lighting circuit, and a compensation circuit. A first light emitting element of the first lighting circuit receives a first driving current when the first transistor switch of the first lighting circuit is turned on. The second light emitting element of the second light emitting circuit receives a second driving current when the second transistor switch of the second light emitting circuit is turned on. When the first light emitting element and the second light emitting element are driven by the first driving current and the second driving current, the compensation circuit provides a compensation current to the first light emitting element or the second light emitting element according to a difference in impedance between the first light emitting circuit and the second light emitting circuit.
