A display device includes a display panel including a plurality of pixels and a drive circuit which displays an image, which corresponds to input data received from outside, on the display panel in a normal operation mode, and displays an image, which corresponds to an analog clock representing a current time, on the display panel based on end point coordinates of clock hands that are internally stored in the drive circuit in a standby mode.

Display device, mobile device including the same, and method of operating display device

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.

Organic light emitting display device

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.
