摘要： The present disclosure relates to a method for driving a display device, a driving apparatus, a display device and a computer-readable medium. The method includes: determining backlight signal values of backlight partitions in a backlight module according to input grayscale values of pixels; adjusting the backlight signal values of the backlight partitions by performing peak stretching processing on the backlight partitions in the condition that a total power consumption of the adjusted backlight module is less than a power threshold of the backlight module; determining backlight signal values of the pixels; determining output grayscale values of the pixels according to the backlight signal values of the pixels and the input grayscale values of the pixels; driving a display panel to display an image according to the output grayscale values of the pixels; and driving the backlight module according to the adjusted backlight signal values of the backlight partitions.

摘要： An image display processing method and an image display processing apparatus (100) for a display apparatus (300), the display apparatus (300), and a storage medium (400). The display apparatus (300) comprises a backlight unit (303), and the backlight unit (303) comprises a plurality of backlight partitions and is driven in a local dimming manner. The image display processing method comprises: according to display data, transmitted in the current frame of image, of pixels corresponding to N rows of backlight partitions, acquiring backlight values of the N rows of backlight partitions; and based on the display data of the pixels corresponding to the N rows of backlight partitions and the acquired backlight values of the N rows of backlight partitions, acquiring compensated display data, in the current frame of image, of the pixels corresponding to the N rows of backlight partitions, wherein the current frame of image corresponds to L rows of backlight partitions, and N is an integer greater than or equal to 1 and less than L. The image display processing method can save on the storage space needed for a display panel, improve the display image contrast and the display effect of a picture, and reduce the power consumption of the display panel.
