<p>The present invention relates to the technical field of displays, and specifically relates to a pixel driving unit, a driving method therefor, and a pixel circuit comprising the pixel driving unit. The pixel driving unit comprises a driving subcircuit and a control subcircuit. The control subcircuit is connected to a data line. The driving subcircuit is connected to the control subcircuit. The pixel driving unit of the present invention allows for effective elimination, in a process of driving a light-emitting component, of non-uniformity for a driving transistor caused by a threshold voltage thereof and of the phenomenon of image persistence caused by threshold voltage drifting. This prevents the problem found in an active-matrix light-emitting organic electroluminescent display transistor of uneven brightness of the active-matrix light-emitting organic electroluminescent display tube caused by a difference in transistor-driving threshold voltages among light-emitting components of different pixel driving units. This increases the driving effect of the pixel driving unit with respect to the light-emitting components, and further increases the quality of the active-matrix light-emitting organic electroluminescent display transistor.</p> |
