Abstract: A display device includes a driving transistor, an organic light emitting diode (OLED), a first switch, and a second switch. The driving transistor has a first terminal (e.g., a drain terminal) and a second terminal (e.g., a source terminal). The OLED includes a first terminal coupled to the second terminal of the driving transistor. The first switch is configured to couple the first terminal of the driving transistor to a first voltage (e.g., VDD) to turn on the OLED, and to couple the first terminal to an intermediate voltage to turn off the OLED. The second switch is configured to couple a second electrode of the OLED to a second voltage (e.g., VSS) to turn on the OLED, and to couple the second electrode of the OLED to the intermediate voltage to turn off the OLED. The intermediate voltage is in between the first voltage and the second voltage.
