Abstract: Structures and methods for improving image quality of organic light emitting diode integrated with color filters, the structures and methods mainly utilize a planarization layer to be coated on the color filter or to substitute for a passivation layer, or utilize a planarization layer to be coated on the color filter and utilize another planarization layer to substitute for a passivation layer to effectively reduce surface roughness of pixel electrode, therefore manufacturing yield and image quality of the organic light emitting diode are improved.

Abstract: A thin-film transistor (TFT) and a method for manufacturing the thin-film transistor using a color filter as a dielectric layer so as to drive an organic light-emitting diode. The thin-film transistor comprises: a substrate; a first poly-silicon mesa formed on the substrate; an insulating layer formed on the substrate and covering the first poly-silicon mesa; a gate metal layer formed on the insulating layer; a color-filtering dielectric layer formed on the insulating layer and covering the gate metal layer, the dielectric layer being provided with a plurality of contact holes penetrating through the dielectric layer and the insulating layer; and a conductive layer formed on the dielectric layer and coupled to the first poly-silicon mesa through the contact holes.
