A method for obtaining a backlight intensity may improving data processing speed of a display device. The method includes: dividing image data into N sets of data; calculating a backlight intensity of each backlight block according to a corresponding set of data; for each group of pixels, calculating a backlight intensity corresponding to a first pixel according to a backlight intensity of each effective backlight block corresponding to the first pixel and a backlight diffusion weight of the effective backlight block corresponding to the first pixel; calculating backlight intensities corresponding to second to Mth pixels in the Tth group of pixels according to the backlight intensities corresponding to first pixels in the Tth group of pixels and a (T+1)th group of pixels; and for a Nth group of pixels, setting the backlight intensity corresponding to the first pixel as backlight intensities corresponding to second to Mth pixels.
