1. A driving circuit for a full-color OLED pixel comprising at least two color thin film layers stacked and insulating layers arranged between any two adjacent thin film layers, comprising:

  • at least two driving sub-circuits which share a data line and a light-emitting control terminal, each of the driving sub-circuits connected to a scanning control terminal corresponding thereto and configured to drive the color thin film layer corresponding thereto,wherein 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,wherein the at least two color thin film layers comprise a first color thin film layer, a second color thin film layer and a third color thin film layer, andthe at least two driving sub-circuits comprise;

    a first driving sub-circuit connected to a first scanning control terminal, the data line and the light-emitting control terminal and configured to drive the first color thin film layer;

    a second driving sub-circuit connected to a second scanning control terminal, the data line and the light-emitting control terminal and configured to drive the second color thin film layer; and

    a third driving sub-circuit connected to a third scanning control terminal, the data line and the light-emitting control terminal and configured to drive the third color thin film layer,wherein the first driving sub-circuit, the second driving sub-circuit and the third driving sub-circuit read the data signals on the data line in sequence under the control of the first scanning control terminal, the second scanning control terminal and the third scanning control terminal; and

    the first driving sub-circuit, the second driving sub-circuit and the third driving sub-circuit drive the first color thin film layer, the second color thin film layer and the third color thin film layer respectively to emit light concurrently under the control of the light-emitting control terminal.
