Abstract: A display device includes a display unit, an external device interface unit configured to receive video having a second frequency from a set-top box converting an original video having a first frequency into the video having the second frequency, and a control unit configured to: determine whether an abnormal output state is detected, based on the video having the second frequency; when the abnormal output state is detected, determine the number of interpolation frames to be generated so as to output the original video having the first frequency as final video having a third frequency through the display unit; and generate interpolation frames as many as the determined number of interpolation frames.

Abstract: A liquid crystal display and a method for driving the same are disclosed. The liquid crystal display includes a display panel which is virtually divided into a plurality of blocks, a backlight unit including a plurality of light sources irradiating light onto the display panel, a backlight dimming controller which analyzes digital video data, calculates a dimming value of each of the blocks, and adjusts a global dimming value based on the dimming values of the blocks so as to increase brightness of the plurality of light sources within previously determined power consumption, and a light source driver which outputs light source driving signals for driving the plurality of light sources based on the dimming values of the blocks and the global dimming value.
