Abstract
An organic light-emitting display panel, a driving method and an organic light-emitting display device are provided. The organic light-emitting display panel includes a first pixel driving circuit, and a second pixel driving circuit disposed adjacent to the first pixel driving circuit along a row direction of a pixel matrix. The first pixel driving circuit is connected to a first scanning signal line, and the second pixel driving circuit is connected to a second scanning signal line. The first and the second pixel driving circuits share a same data line. The same data line is configured to time-sharingly provide an initialization signal to the first and the second pixel driving circuits, time-sharingly detect threshold voltages of driving transistors in the first and the second pixel driving circuits, and time-sharingly provide a compensated data signal to the first and the second pixel driving circuits.
