Abstract
The present disclosure discloses an OLED panel, including: a substrate and a driving thin film transistor, a switching thin film transistor, a storage capacitor, an organic light emitting device, and a light emitting device formed on the substrate, an external voltage signal is stored in the storage capacitor via the switching thin film transistor, the external voltage signal controls a magnitude of on-current of the driving thin film transistor to control the gray scale of the organic light emitting device. The present disclosure further discloses a manufacturing method of OLED panel. In the present disclosure, the drain of the low temperature polysilicon thin film transistor is in contact with the bottom electrode of the organic light emitting device so that the current supplied to the organic light emitting device is stabilized; metal-oxide-semiconductor thin-film transistor has a low leakage current, so that a better circuit-closing effect can be achieved.
