Display system and method

The invention provides a display system and a method. The display device includes a plurality of pixel circuits and a controller. Each pixel circuit includes at least one sub-pixel circuit having a plurality of components, the plurality of components include at least one driving transistor, at least one storage element, and at least one light emitting element. Each sub-pixel circuit includes at least two dedicated sub-pixel portions, each dedicated sub-pixel portion including at least one dedicated component of the same type and for the same function, and operating differently from each otherfor at least one operating range. The controller is configured to: control an operation of the at least two dedicated sub-pixel portions based on the operating range; select and drive at least one sub-pixel circuit while a first one of the at least two dedicated sub-pixel portions is active for the first operating range and a second one of the at least two dedicated sub-pixel portions is deactivated; select and drive at l
