Abstract: A driving circuit for a full-color OLED pixel and a driving method of the driving circuit. The full-color OLED pixel comprises at least two color thin film layers stacked (Color1, Color2, Color3) and insulating layers (Ins1, Ins2) arranged between any two adjacent thin film layers. The driving circuit comprises at least two driving sub-circuits, the at least two driving sub-circuits share a data line (DATA) and a light-emitting control terminal (EM), and each of the driving sub-circuits is connected to a scanning control terminal corresponding thereto (SCAN1, SCAN2, SCAN3) and is configured to drive the color thin film layer corresponding thereto. The at least two driving sub-circuits read data signals on the data line in sequence under the control of the respective scanning control terminals, and drive the respective color thin film layers to emit light concurrently under the control of the light-emitting control terminal. Full-color display of the full-color OLED pixel is achieved by reading in sequence corresponding data signals for the at least two color thin film layers stacked and controlling the at least two color thin film layers to emit light concurrently.

Abstract: A pixel structure, a driving method thereof and a display device are provided. The pixel structure includes a plurality of closely arranged repeating groups, and each of the repeating groups includes linearly arranged square pixel units of different colors. Each of the square pixel units in each of the repeating groups is formed by two sub-pixels with a same color and a same shape; and two sub-pixels in adjacent square pixel units have different arrangement modes. The repeating groups disposed on two adjacent parallel straight lines are staggered by a distance of one and a half square pixel units. With such a pixel structure, input information is subjected to brightness redistribution and intensively outputted to the actual physical positions, the optional switching of the sub-pixels can be applied on the premise of not reducing the pixel size, and hence the resolution of the display image can be improved.
