Abstract

The invention provides a thin film transistor device, a backlight module and a display panel. The thin film transistor device comprises a source electrode part, an active layer located on the source electrode part, a drain electrode part separated from the source electrode part, and a conductor part located on the active layer and extending to the drain electrode part, according to the invention, the active layer is arranged on the source electrode part, and the drain electrode part and the active layer are electrically connected through the conductor part, so that the current can be transmitted to the active layer from the drain electrode part through the conductor part, and further, the current is transmitted to the source electrode part along the thickness direction of the active layer, thereby shortening the transmission path of the current, increasing the driving current of the thin film transistor device, and improving the backlight intensity of the backlight module and the luminous intensity of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a thin film transistor device, a backlight module and a display panel. Background technique [0002] Compared with the traditional LED (Light-Emitting Diode, light-emitting diode) backlight, the Mini LED (Mini Light-Emitting Diode, light-emitting diode) backlight can achieve a million-level contrast ratio to improve display quality. [0003] At present, the Mini LED backplane is driven by current, but the thin-film transistor device used to drive the Mini LED is limited by mobility, stability, or process accuracy. The final output current of the thin-film transistor device is low, which makes it impossible for the Mini LED to obtain a large enough The drive current reduces the backlight intensity of the Mini LED backplane. [0004] Therefore, it is necessary to provide a thin film transistor device, a backlight module and a display panel that can increase the driving current of...
