Abstract
An AMOLED display panel comprises a display area and a non-display area. The display area has a plurality of pixel electrodes and the neighboring pixel electrodes are spaced apart from each other. The non-display area surrounds the display area and comprises a virtual pixel area and a boundary area. The virtual pixel area is close to the display area and has a plurality of virtual electrodes. At least part of the virtual electrodes are disposed close to the pixel electrodes at a boundary of the display area. The virtual electrodes and the pixel electrodes are formed by the same manufacturing process. The boundary area is close to the virtual pixel area or both the virtual pixel area and the display area. The virtual pixel area is located between the display area and the boundary area. The present invention may improve display uniformity of the AMOLED display panel.
