发明名称 Pixel, display device and driving method thereof
摘要 A pixel, a display device using the pixel and a method of driving the display device are provided. The pixel may include an organic light emitting diode, a driving circuit for generating and transmitting driving current depending on data signals to the organic light emitting diode, and at least one switch connected between a power wire for applying a first voltage to the organic light emitting diode and a data line for transmitting the data signals. The at least one switch may include a compensating circuit for electronically connecting the power wire to the data line for a predetermined period to transmit the first voltage through the data line.
