  • Patent number: 10665161
    Abstract: A transistor circuit outputs a drive current in accordance with a data signal. An OLED that is connected to the transistor circuit emits light with luminance corresponding to the drive current. A discharge transistor, when the OLED does not emit the light, is turned on to connect a discharge feeder line to a node at which the transistor circuit is connected to the OLED. An absolute value of a threshold voltage of the discharge transistor is lower than an absolute value of a threshold voltage of a drive transistor in the transistor circuit. When the data signal indicates zero, the discharge transistor can cause a flow of the drive current from the transistor circuit to bypass the OLED.
