Abstract: A backlight module and a display panel are provided. The display panel includes a main body and a backlight module. The backlight module includes a light source and a light guide plate. By accommodating a light-emitting chip of the light source into a groove of the light guide plate, misalignment of the light source and the light guide plate is prevented so that a relative positional relationship between the light source and the light guide plate is always consistent, thereby improving the consistency and stability of the light effect of a lamp port of the backlight module.

Abstract: A gate driving circuit and a display panel are disclosed. A pull-up control module and a pull-down module of each stage gate driving unit are connected to a first node. A thin film transistor in the pull-up control module and/or pull-down module that is connected to the first node is an oxide thin film transistor, such that a leakage current of the first node is reduced due to the advantage of the small off-state leakage current of the oxide thin film transistor. Therefore, the voltage level of the first node can remain stable during a pull-up stage and a touch suspension stage.
