摘要： A display device may include a display panel including a plurality of pixels, a data driver which applies data signals to the display panel, a scan driver including scan stages, which sequentially applies scan signals to the display panel, an emission driver including an emission stage which sequentially applies emission signals to the display panel, and a power supply voltage generator which generates a power supply voltage including high voltages and low voltages, and provides the high voltages having different voltage levels from each other or the low voltages having different voltage levels from each other to at least one selected from the scan stages and the emission stage. The power supply voltage generator generates a first high voltage, a first low voltage, a second high voltage lower than the first high voltage, and a second low voltage higher than the first low voltage based on an input voltage.

摘要： An organic light emitting display apparatus includes first and second pixels on a display region, first and second scan lines connected to the first and second pixels respectively, and a gate driver to output a first scan signal and a second scan signal to the first and second scan lines respectively. The first pixel includes a first pixel circuit and a first organic light emitting diode (OLED). The second pixel includes a second pixel circuit and a second OLED. Each of the first and second pixel circuits includes a driving transistor to output driving current to the anode of a respective one of the first and second OLEDs. The anode of the second OLED at least partially overlaps the gate of a driving transistor of the first pixel circuit.
