Abstract:
An array substrate includes a pixel circuit and a light-emitting diode. The pixel circuit includes a driving transistor including a first active medium made of polysilicon, and a switching transistor including a second active medium made of polysilicon. The first active medium has a first grain size. The second active medium has a second grain size larger than the first grain size. The light-emitting diode is coupled to the pixel circuit.
