ORGANIC LIGHT EMITTING DISPLAY DEVICE

摘要

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.

1. An organic light emitting display device comprising:
a display panel including a pixel; a scan driver which provides a scan signal to the pixel; a data driver which provides a data signal to the pixel; a power supply which provides a first voltage to a first power terminal of the pixel and to selectively provide the first voltage or a second voltage of which a voltage level is lower than a voltage level of the first 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 and controls the scan driver, the data driver, and the power supply corresponding to the panel driving mode, wherein 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.
