A display apparatus and a method for controlling the same are provided. The method for controlling the display apparatus according to the present disclosure includes receiving an image; distinguishing the image into a plurality of blocks to detect a maximum pixel value each of the plurality of blocks; determining a target diffuser value usable for compensating for a duty of a backlight based on the detected maximum pixel value for each block; and driving the backlight for each of the plurality of blocks based on a backlight duty value compensated based on the target diffuser value. Therefore, the display apparatus according to the present disclosure may address a problem that gradation overcompensation occurs in a region of a certain block, when the backlight is driven in a unit of the plurality of blocks, using a local dimming mode.

Display apparatus and method for driving a backlight to prevent or reduce gradation overcompensation

A display apparatus which outputs a stereoscopic image and a control method thereof, the display apparatus includes: an image input part which receives left and right eye image frames; an image processor which generates a left eye image interpolation frame by using a gradation difference of areas between a previous right eye image frame of the left eye image frame and the left eye image frame and generates a right eye image interpolation frame by using a gradation difference of areas between a previous left eye image frame of the right eye image frame and the right eye image frame; a display which displays the left eye image interpolation frame, the left eye image frame, the right eye image interpolation frame, and the right eye image frame sequentially according to a preset order; and a controller which controls the image processor to generate the left and right eye image interpolation frames.
