1. A display system, comprising a display module, a signal control module, an image processing module, a backlight control module and backlight source modules;
the signal control module is configured to, upon reception of an image scaling mode signal for an image scaling mode currently selected by a user, acquire an image scaling ratio for each frame of image and a position intended to display a scaled image on the display module, carried in the image scaling mode signal, transmit the image scaling signal and an image composition signal to the image processing module, and transmit a backlight control signal to the backlight control module; the image processing module is configured to scale each frame of image to be output to the display module according to the image scaling ratio, upon reception of the image scaling signal, and synthesize the scaled image and a background image into a frame of composition image upon reception of the image composition signal; the display module is configured to display the composition image upon reception of the composition image; and the backlight control module is configured to, upon reception of the backlight control signal, control only the backlight source modules in a backlight area, corresponding to the position intended to display the scaled image, among the backlight source modules, to be turned on. |
