Active matrix organic light emitting diode display panel circuit |
摘要 |
An active matrix organic light emitting diode display panel circuit capable of reducing current and brightness nonuniformities between pixels by including a threshold voltage compensation circuit block between a data line and the pixels is provided. The threshold voltage of a video signal loaded in a data line is compensated for while the video signal passes through the threshold voltage compensation circuit block and then provided to a driving transistor of the pixels. One threshold voltage compensation circuit block is connected commonly to a plurality of pixels, rather than be connected to every pixel, so that threshold voltage compensation can be achieved for high-quality, large-sized displays, without increasing the number of transistors for the pixels.
