A mobile terminal and an application processor are provided. The mobile terminal includes a power management module, an application processor, a display driver chip, and a display panel. The power management module is used to output a power supply voltage to the application processor, the display driver chip, and display panel. The application processor includes a graphics processor, a graphics random access memory and a display serial interface, where the graphics random access memory is communicably connected with a codec overlay hardware of the graphic processor, and is used to receive and store an image frame outputted by the graphic processor. The graphic random access memory is communicably connected to the display serial interface to output a stored image frame to the display driver chip through a display serial interface. The display driver chip controls the display panel to display the received image frame.
