Driving circuit for full-color organic light-emitting diode pixel and driving method of the driving circuit
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.
