ORGANIC LIGHT EMITTING DIODE DISPLAY AND DRIVING METHOD THEREOF |
摘要 |
An organic light emitting diode (OLED) display and a method of driving the same are provided. The OLED display includes: a plurality of pixels arrayed in a matrix, each of which includes a switching transistor and a driving transistor; a plurality of data lines connected to the switching transistors, which transmit a data voltage to the pixels; a plurality of driving voltage lines that transmit a driving voltage to the driving transistors; a voltage generator that applies the driving voltage to the driving voltage lines; a current sensing unit that senses a driving current that flows from the voltage generator to the driving voltage lines; a gray voltage generator that generates a gray voltage depending on a change in the driving current; and a data driver that converts an input image signal into the data voltage on the basis of the gray voltage and applies the data voltage to the data lines. |
