摘要： The present invention proposes a low temperature poly-silicon thin-film transistor having a dual-gate structure and a method for forming the low temperature poly-silicon thin-film transistor. The low temperature poly-silicon thin-film transistor includes: a substrate, one or more patterned amorphous silicon (a-Si) layers, disposed in a barrier layer on the substrate, for forming a bottom gate, an NMOS disposed on the barrier layer, and a PMOS disposed on the barrier layer. The NMOS comprises a patterned gate electrode (GE) layer as a top gate, and the patterned GE layer and the bottom gate formed by the one or more patterned a-Si layers form a dual-gate structure.

The GOA circuit can be driven in 2D and 3D driving modes to prolong charging time of each pixel. Each two GOA circuit units share a set of Nth stage start pulse signals, Nth stage gate pulse signals and eight clock pulse signals. Because the charging time of each pixel is prolonged, the display device can show images with better display quality.
