  • Patent number: 11114028
    Abstract: The present disclosure provides a display device capable of determining the characteristics of the light emitting diode without having to consider various factors dependent upon the manufacturing process. The light emitting diode includes an internal resistor and a parasitic capacitor. The light emitting diode is connected to a sensing circuit including an integrator that has a sensing resistor and a feedback capacitor. Based on a first sensing of a pixel along a first sensing path and a second sensing of the pixel along the second sensing path, the sensing circuit senses a first charge amount from the first sensing path and a second charge amount from the second sensing path. The characteristics of the light emitting diode can be determined by dividing the first charge amount and the second charge amount, which is based on the ratio of the sensing resistor and the internal resistor.
