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.

Abstract: Provided is a display device. The display device includes a base layer including an active area partitioned to display images and an inactive area adjacent to the active area, an opening located in a part of the active area and passing through the base layer and functional layers thereabove, and a cut structure located in the vicinity of the opening and provided to cut the connection of an organic light emitting layer between the opening and a light emitting unit. A camera may be provided in a position corresponding to the opening.
