Embodiment Construction
[0029]FIG. 1A is a schematic circuit drawing of an active matrix organic light-emitting diode (AMOLED) pixel structure. Referring to FIG. 1A, an AMOLED is disposed on a transparent substrate and the pixel structure thereof includes an OLED, a data line Yn, a scan line Xn, a switch TFT T1, a driving TFT T2 and a storage capacitor Cst. The gate of the switch TFT T1 is coupled to the scan line Xn, while the source thereof is coupled to the data line Yn and the drain thereof is coupled to the gate of the driving TFT T2 and the storage capacitor Cst. The drain of the driving TFT T2 is coupled to the OLED, while the source thereof is coupled to a power line Vdd. The storage capacitor Cst is formed by two transparent electrodes and a dielectric layer between the two electrodes. The lower electrode of the storage capacitor Cst is electrically connected to the drain of the switch TFT T1 and the gate of the driving TFT T2 and is a transparent semiconductor layer. The material of the transpare...
