Abstract
An exemplary embodiment of a system comprises an active matrix organic electroluminescent device, having a substrate, and a plurality of scan lines and data lines disposed on the substrate, for defining a plurality of pixel regions. Each pixel structure comprises: a switching thin film transistor, a driving thin film transistor, and a storage capacitor. The switching TFT has a light-shielding layer adapted for preventing the sunlight from being incident into the switching TFT. The driving TFT is a bottom gate thin film transistor and have advantages of precisely controlling the current provided to the organic electroluminescent diode. Further, since the storage capacitor has a multilayer structure and occupies a reduced pixel area, the aperture ratio of the pixel structure can be increased.
