    IPC: G09G3/3233

    Abstract: A pixel includes a light emitting element, a driving switching element, an initialization voltage terminal, a data initialization switching element set, and an adjustment switching element. The driving switching element may provide a driving current to the light emitting element. The adjustment switching element is electrically connected to the data initialization switching element in series. At least one of the data initialization switching element set and the adjustment switching element may control an electrical connection between the control electrode of the driving switching element and the initialization voltage terminal. A control electrode of the adjustment switching element is electrically connected to an input electrode of the adjustment switching element.
