Pixel of a display device, and display device

An electronic device comprising:

• a processor configured to provide input image data;
• and
• a display device configured to receive the input image data from the processor, and to display an image based on the input image data, the display device including a pixel, the pixel comprising:
• a first transistor including a gate coupled to a first node, a drain coupled to a first power supply voltage line, and a source coupled to a second node;
• a first capacitor coupled between the first node and the second node;
• a second transistor including a gate, which receives a first signal, a first terminal coupled to a data line, and a second terminal coupled to the first node;
• a third transistor including a gate, which receives a second signal, a first terminal, which receives a reference voltage, and a second terminal coupled to the first node;
• a light emitting element including an anode, and a cathode coupled to a second power supply voltage line;
• a fifth transistor including a gate, which receives a fourth signal, a drain coupled to the second node, and a source coupled to the anode;
• and
• a sixth transistor including a gate, which receives a third signal, a first terminal coupled to the anode, and a second terminal, which receives an initialization voltage,
• wherein, in a threshold voltage compensation period, a power supply voltage is applied to the drain of the first transistor through the first power supply voltage line, the reference voltage is applied to the gate of the first transistor through the third transistor, the third transistor transfers the reference voltage to the first node, and the first transistor changes a voltage of the second node to a voltage corresponding to a threshold voltage of the first transistor subtracted from the reference voltage, and
• wherein during the threshold voltage compensation period, the third transistor is turned on, and the second and fifth transistors are turned off.
