Claim 0:
1. A mobile terminal, comprising:
a power management module, an application processor, a display driver chip and a display panel, wherein,
the power management module is used to output a power supply voltage to the application processor, the display driver chip, and the display panel;
the application processor includes: a graphics processor, a graphics random access memory, and a display serial interface, wherein the graphics random access memory is communicably connected with a codec overlay hardware of the graphics processor, and is used to receive and store an image frame outputted by the graphics processor; the graphics random access memory is further communicably connected with the display serial interface, and is used to output a stored image frame to the display driver chip through the display serial interface;
the display driver chip controls the display panel to display the received image frame,
wherein the mobile terminal further comprises:
a graphics compression circuit and a graphics decompression circuit both the graphics compression circuit and the graphics decompression circuit are arranged in the application processor, wherein,
the graphics compression circuit is connected in series between the codec overlay hardware of the graphics processor and the graphics random access memory, and is used to compress the image frame outputted by the graphics processor and output the compressed image frame to the graphics random access memory;
the graphics decompression circuit is connected in series between the display serial interface and the graphics random access memory, and is used to decompress an image frame stored in the graphics random access memory and output the decompressed image frame to the display serial interface.
