Abstract

Embodiments of the present invention relate to a double thin film transistor, a method for fabricating the same, and a display panel. The double thin film transistor includes a first thin film transistor, a second thin film transistor, and a substrate; The first thin film transistor is located on the first surface of the substrate; the second thin film transistor is located on the second surface of the substrate; the drain of the first thin film transistor is electrically connected to the drain of the second thin film transistor through the hole The connection is so that the potentials are equal, so as to realize the double output of the leakage current and improve the refresh efficiency of the display panel.

Description

technical field [0001] The invention relates to the field of semiconductor devices, in particular to a double thin film transistor, a preparation method thereof, and a display panel. Background technique [0002] In the current flat panel display, thin film transistors are widely used as the basis of active drive display in order to achieve high resolution, so as to obtain high-speed image conversion and higher-resolution display effects. Among them, thin film transistors are an important part of active driving, and the current mainstream driving devices are amorphous silicon, polysilicon and oxide thin film transistors. Among them, as a mature driving manufacturing technology, amorphous silicon thin film transistor (TFT) device has the characteristics of low cost, less process and high yield, which makes this driving scheme widely used in low resolution high-rate TV panels as well as low-end flat-panel displays. For most high-end mobile phones on the market, Active-Matrix...
