Patent ID: 8330687

Claim:
A liquid crystal display comprising: a system board for identifying a driving frequency of video data and supplying the video data and control signals at a first driving frequency or second driving frequency as a result of the identification; a timing control board including a timing controller for processing the video data and control signals from the system board, the timing control board supplying the processed video data and control signals at the first or second driving frequency; and a liquid crystal panel for displaying an image based on the video data and control signals supplied from the timing control board, wherein the system board comprises a video processor for processing the video data and control signals externally input thereto at the first or second driving frequency as the identification result, wherein the video processor modulates the inputted video data and control signals at the first or second driving frequency at which they are to be outputted and transfers the modulated video data and control signals to the first interface, wherein the system board identifies the driving frequency of the video data received by the system board from outside or the driving frequency of the video data to be outputted to the timing control board.
