A display system and method for the same is provided. A display includes a plurality of pixels, each having a light emitting device and a driving transistor for driving the light emitting device, the driving transistor and the light emitting device being coupled i n series between a first power supply and a second power supply. The method includes: at a firs t frame, programming a pixel with a first programming voltage different from a programming voltage for a valid image, and charging at least one of the first power supply and t he second power supply so that at least one of the driving transistor and the light emitting device is under a negative bias. The pixel circuit includes: a light emitting device; a drivin g transistor for driving the light emitting device, the driving transistor having a gate terminal, a first terminal coupled to the light emitting device, and a second terminal; a storage capacitor; a first switch transistor coupled to a data line for providing a programming data and the gate termina l of the driving transistor; and a second switch transistor for reducing a threshold voltage shift of the driving transistor, the storage capacitor and the second switch transistor being coupled in parallel to the gate terminal of the driving transistor and the first terminal ofthe driving transistor. The method includes: at a first cycle, implementing an image display operation having programming the pixel circuit for a valid image and driving the light emitting device; a nd at a second cycle, implementing a relaxation operation for reducing a stress on the pixel circuit, including: selecting a relaxation switch transistor coupled to the storage capacitor in parallel. |
