Title:
PIXEL CIRCUIT, MANUFACTURING METHOD THEREOF, AND DISPLAY DEVICE.
Document Type and Number:
WIPO Patent Application WO/2019/024760
Kind Code:
A1
Abstract:
A pixel circuit (10), comprising a substrate (100), a first thin film transistor (11) provided thereon, and a second thin film transistor (12), wherein the first thin film transistor (11) has a top gate structure and the second thin film transistor (12) has a bottom gate structure. A first electrode (211) of the first thin film transistor (11) and a gate electrode (212) of the second thin film transistor (12) are electrically connected with each other and disposed on the same layer of the substrate (100). The pixel circuit (10) has high switching speed and a large driving current. A manufacturing method therefor is easily executed with minimal production costs.
