Abstract: An organic light emitting display device includes a display panel, a scan driver, a data driver, a power supply which provides a first voltage to a first power terminal of the pixel and selectively provides the first voltage or a second voltage to a second power terminal of the pixel, and a controller which selects one of a normal driving mode and a power saving mode as a panel driving mode where the power supply provides the second voltage to the second power terminal of the pixel in a first period of one frame period and provides the first voltage to the second power terminal of the pixel in a second period of one frame period when the panel driving mode is the power saving mode.

Abstract: A display device includes a display panel, a power supply, and a driving circuit. The display panel includes a plurality of pixels. The power supply is configured to supply a first power voltage and a second power voltage to the display panel. The driving circuit is configured to determine, based on a viewing angle information signal, whether to operate the display device in a general mode or a low power mode. If the display device is operated in the low power mode, the driving circuit is further configured to deactivate the power supply, and supply a first subsidiary power voltage and a second subsidiary power voltage to the display panel.
