Abstract:
A transflective pixel structure suitably formed on a substrate, the pixel structure comprising:a scan line formed on the substrate; a gate dielectric layer formed on the substrate to cover the scan line; a data line formed on the gate dielectric layer and extending with a direction different from that of the scan line; a protection layer formed on a part of the gate dielectric layer to cover the data line; a transparent pixel electrode formed on the protection layer; a reflective pixel electrode formed on the exposed gate dielectric layer; and a double-drain thin-film transistor formed on a center of the pixel structure, further comprising a gate, a source region electrically connected to the data line, two drain regions electrically connected to the transparent pixel electrode and the reflective pixel electrode, respectively, a channel layer located on the gate dielectric layer over the gate, wherein the source and drain regions are formed on the channel layer, and the gate is electrically connected to the scan line.
