Patent ID: 8797370

Claim:
A liquid crystal display comprising: a liquid crystal display panel configured to selectively display a 2D image and a 3D image in response to a mode signal; a backlight unit including a plurality of light sources divided into a plurality of predetermined blocks that light the liquid crystal display panel; a backlight driving circuit configured to individually drive the plurality of predetermined blocks based on a dimming value of each block in an Nth frame; and a local dimming control circuit configured to when the mode signal is a 2D mode signal, calculate a pixel gain value in an (N+1)th frame based on the dimming value of each block in the Nth frame, and apply the pixel gain value to the (N+1)th frame, and when the mode signal is a 3D mode signal, calculate a pixel gain value in an (N+4)th frame based on the dimming value of each block in the Nth frame, and apply the pixel gain value to the (N+4)th frame, wherein N is a positive integer.
