Patent ID: 7460092

Claim:
An organic electroluminescent display, comprising: a panel including a plurality of data lines, a plurality of scan lines crossing the data lines, and a plurality of pixel circuits that are located at areas approximately corresponding to places where the data lines and scan lines cross and that have organic electroluminescent elements; a scan driver for applying scan signals to the scan lines; a data driver for applying data voltages corresponding to gray data to the data lines; a temperature sensor for sensing the temperature of the panel; and a power supply voltage generator for generating a power supply voltage corresponding to the temperature sensed by the temperature sensor, and supplying it to the pixel circuit of the panel, wherein the power supply voltage generator comprises: a DC/DC converter for receiving a DC power supply voltage, converting it into a first power supply voltage for driving the pixel circuit, and outputting the first power supply voltage; a voltage controller for receiving the first power supply voltage output by the DC/DC converter, and converting it into a second power supply voltage to be supplied to the pixel circuit; and a controller for controlling the voltage controller to output the second power supply voltage according to the temperature of the panel.
