Abstract

An embodiment of the disclosed technology provides a driving device for a thin film transistor liquid crystal display (TFT-LCD) and a method for manufacturing the same. The driving device comprises at least one first TFT and at least one second TFT formed a base substrate, wherein load of the first TFT is larger than load of the second TFT, the first TFT is of a top-gate configuration, and the second TFT is of a bottom-gate configuration.

Description

technical field [0001] The present invention relates to the technical field of flat panel displays, in particular to a Thin Film Transistor Liquid Crystal Display (TFT-LCD for short), a driving device and a manufacturing method thereof. Background technique [0002] Most of the driving devices in the TFT-LCD are implemented by a silicon integrated circuit (Silicon Integrated Circuit, IC for short). In recent years, with the continuous improvement of the thin film transistor technology, the technology of integrating the thin film transistor on the array substrate of the TFT-LCD to form the driving device has gradually appeared. For example, a gate line driving device, a data line driving device and the like made of amorphous silicon thin film transistors can be formed on the array substrate. [0003] When amorphous silicon thin film transistors are used to form driving devices, some thin film transistors need to have strong driving capabilities. In order to achieve a strong...
