摘要： An organic electroluminescent display device employing a demultiplexer to reduce the number of output lines of a data driver. The display device uses the demultiplexer to store a data voltage in a data line, and supplies the stored data voltage to a pixel when a scan signal is applied, thereby displaying an image. Here, the data voltage supplied to the pixel is lowered because an electric charge is shared between a data line capacitor and a storage capacitor in the pixel. To compensate for the lowered data voltage, an auxiliary capacitor is provided for generating a compensation voltage. Here, the auxiliary capacitor increases the data voltage according to a level change of the scan signal. Therefore, a decrease in level of the voltage applied to the pixel is reduced or prevented so that DC/DC efficiency is enhanced without lowering a power supply voltage and a reference voltage.

摘要： In an organic electroluminescent (EL) display device, a main display panel and a sub display panel share a data line and a power supply voltage line. The organic EL display device has a top emission type main display panel and a bottom emission type sub display panel in a single display panel. The main display panel is composed of main pixels, each having a compensation circuit for compensating a threshold voltage, and the sub pixel display is composed of basic sub pixels without any compensation circuit. Each of the sub pixels has a boost capacitor which increases a data voltage, and which is disposed between a scan line and a storage capacitor so as to use the same voltage and power supply voltage as the main pixels. The sub pixels having the boost capacitor are disposed in the sub display panel, so that the main and sub display panels share the data line and the power supply voltage line.
