    • A pixel includes a light emitting diode, and a switching circuit that is coupled to a data line, and includes a transistor including a control terminal, a first main terminal coupled to a power source line, and a second main terminal coupled to the light emitting diode. The switching circuit generates a control signal based on at least a voltage of a data signal transmitted through the data line and a voltage drop of the light emitting diode, and applies the control signal to the control terminal of the first transistor to control a current flowing in the light emitting diode so that the current varies in accordance with the voltage of the data signal and is independent of variations in the voltage drop of the light emitting diode.
    • 像素包括发光二极管和耦合到数据线的开关电路,并且包括晶体管,其包括控制端子,耦合到电源线的第一主端子和耦合到发光二极管的第二主端子 二极管。 开关电路至少基于通过数据线传输的数据信号的电压和发光二极管的电压降产生控制信号,并将控制信号施加到第一晶体管的控制端,以控制电流流动 在发光二极管中使得电流根据数据信号的电压而变化,并且与发光二极管的电压降的变化无关。
