Display device and method for driving the same, driving apparatus, and computer-readable medium

A driving apparatus, comprising:

• a memory configured to store instructions;
• at least one processor which executes the instructions stored in the memory to:
• determine backlight signal values of a plurality of backlight partitions in the backlight module according to input grayscale values of pixels in an image to be displayed;
• adjust the backlight signal values of the plurality of backlight partitions by performing peak stretching processing on at least one of the plurality of backlight partitions having a backlight signal value greater than a peak stretching threshold, so that a total power consumption of the plurality of backlight partitions in the backlight module is less than a power threshold of the backlight module;
• determine backlight signal values of the pixels in the image to be displayed according to the adjusted backlight signal values of the plurality of backlight partitions;
• determine output grayscale values of the pixels according to the backlight signal values of the pixels and the input grayscale values of the pixels;
• drive the display panel using the determined output grayscale values of the pixels;
• and
• drive the backlight module using the adjusted backlight signal values of the plurality of backlight partitions.
