Patent attributes
A display device includes a pixel circuit that supplies current to a light emitting diode (LED) and a driver circuit. The pixel circuit includes a constant current circuit including a first transistor and a capacitor connected to a gate terminal of the first transistor, and a switch circuit including a second transistor. The driver circuit controls the pixel circuit such that the LED emits light by connecting the anode of the LED diode and the first power line under a non-light emission state of the LED, connecting the gate terminal of the first transistor and the anode after the anode is disconnected from the first power line, setting the gate terminal of the first transistor to a voltage corresponding to an amount of a supply current from the first power line, and after setting the gate terminal, switching a state of the LED into a light emission state.
