Abstract: An OLED driving circuit is disclosed. The OLED driving circuit includes at least two types of pixel driving circuits for driving each pixel of an OLED display panel. The at least two types of the pixel driving circuits have different types and/or amounts of elements so a different pixel driving circuit is designed for each pixel. In comparison with a current display panel using the same driving circuit, a part of the pixel driving circuit is simplified to simplify a structure and to reduce a space occupied by the OLED driving circuit on an effective area of the display panel.

Abstract: A pixel circuit, driving method for the same and an organic light-emitting display are provided. The pixel circuit includes: a resetting module transmitting a reset voltage to a compensation module under the control of the first control signal; the compensation module compensating a threshold voltage under the control of the second control signal; a writing module transmitting a data signal to the compensation module under the control of the third control signal; and a light-emitting module emitting light under the control of a light-emitting control signal. The present invention can eliminate a bad display problem caused by the drift of the threshold voltage of a driving TFT.
