Patent ID: 8593493

Claim:
A display device comprising: a liquid crystal panel including a plurality of regions, wherein each of the plurality of regions includes a plurality of liquid crystal pixels; a plurality of data driving units; and a plurality of timing controllers, wherein the plurality of data driving units is in a one-to-one correspondence with the plurality of regions, wherein each of the plurality of data driving units controls transmittance of light of the plurality of liquid crystal pixels in a corresponding region thereof, wherein the plurality of timing controllers is in a one-to-one correspondence with the plurality of data driving units, wherein each of the plurality of timing controllers acquires data of a partial image to be displayed at the corresponding region of a corresponding data driving unit thereof, generates control data for controlling the transmittance of light of the plurality of liquid crystal pixels in the corresponding region of the corresponding data driving unit thereof, and outputs the control data to the corresponding data driving unit thereof, wherein each of the plurality of timing controllers comprises: a luminance distribution extracting unit which extracts luminance distribution information of the partial image, wherein each of the plurality of timing controllers is one of a master timing controller and a slave timing controller, and wherein the master timing controller sends a request on the luminance distribution information to the slave timing controller.
