PIXEL OF AN ORGANIC LIGHT EMITTING DISPLAY DEVICE AND ORGANIC LIGHT EMITTING DISPLAY DEVICE

摘要

A pixel of an organic light emitting display device includes a first capacitor, second capacitor, and a number of transistors. The first capacitor stores an emission data voltage from a data line. The second capacitor stores a scan data voltage from the data line. A switching transistor is selectively turned on or off in response to the scan data voltage stored in the second capacitor. When the switching transistor and the driving transistor are turned on, an organic light emitting diode is driven to display an image.

主权项

1. A pixel of an organic light emitting display device, the pixel comprising:
a first switching transistor configured to be turned on in response to a switching signal; a first storage capacitor configured to store an emission data voltage applied through a data line while the first switching transistor is turned on; a driving transistor configured to be turned on in response to the emission data voltage stored in the first storage capacitor; a second switching transistor configured to be turned on in response to a scan signal; a second storage capacitor configured to store a scan data voltage applied through the data line while the second switching transistor is turned on; a third switching transistor coupled in series to the driving transistor and configured to be selectively turned on or off in response to the scan data voltage stored in the second storage capacitor; and an organic light emitting diode configured to be driven by the turned-on driving transistor when the third switching transistor is turned on.
