Abstract
A display device includes a display panel in which a plurality of sub pixels is defined; a first light emitting diode which is disposed in each of the plurality of sub pixels; a second light emitting diode which is connected to the first light emitting diode in series; a first control transistor which is connected to the first light emitting diode in parallel and is turned on by a first control signal; and a second control transistor which is connected to the second light emitting diode in parallel and is turned on by a second control signal. Accordingly, the first light emitting diode and the second light emitting diode may be independently controlled using the first control transistor and the second control transistor.
Claims11
A display device, comprising:
- a display panel including a plurality of sub pixels;
- a first light emitting diode in each of the plurality of sub pixels;
- a second light emitting diode that is connected to the first light emitting diode in series;
- a first control transistor that is connected to the first light emitting diode in parallel, the first control transistor turned on by a first control signal;
- a second control transistor that is connected to the second light emitting diode in parallel, the second control transistor turned on by a second control signal;
- and
- a gate driver that is electrically connected to the display panel, the gate driver configured to output a first scan signal, the first control signal, and the second control signal to the plurality of sub pixels,
- wherein the gate driver includes:
- a plurality of first stages that generate the first scan signal;
- and
- a plurality of control signal generating circuits each of which is connected to an output terminal of a corresponding one of the plurality of first stages and generates the first control signal and the second control signal to output the first control signal and the second control signal to a first control line and a second control line, and
- wherein the first light emitting diode and the second light emitting diode emit light of a same color.
