The present disclosure relates to a display driving method, device and device, an original gray scale data group of the pixel units in the preset display area and of the content to be displayed is acquired; average gray scales of each of the hues in the preset display area are determined according to the original gray scale data group; original light source intensities of the hues in the preset display area and of the content to be displayed are acquired; the original gray scale data group is divided into a first gray scale data group and a second gray scale data group and the driving light source intensities of each of the hues in the preset display area are determined according to the original gray scale data group of the pixel units, the average gray scales of each of the hues, and the original light source intensities; the gray scales of each of the hues of the first gray scale data group are the maximal gray scale in the original gray scale data group; the gray scales of each of the hues of the second gray scale data group are 0 or greater than the minimal gray scale of the original gray scale data group. The brightness difference between the hue of the low gray scale of the side view angle and the hue of the overall pixel unit is reduced, such that the hue of the side view angle is presented close to the hue of the front view angle.
