Patent ID: 7808469

Claim:
A liquid crystal display system which enlarges and displays an image represented by video signals, comprising: a control circuit to input the video signals in accordance with input synchronizing signals and to output the video signals in accordance with output synchronizing signals; a display panel to display the image represented by the video signals; and a processing circuit to enlarge the image represented by the video signals a non-integer number of times in accordance with a resolution of the display panel divided by a resolution of the image represented by the video signals; wherein once in every M times the input synchronizing signals are generated and N times the output synchronizing signals are generated, the output synchronizing signals come to correspond to the input synchronizing signals, and wherein the number N is not equal to the number M; the number N divided by the number M is a non-integer number; the number N divided by the number M corresponds to the resolution of the display panel divided by the resolution of the image represented by the video signals; and a generation cycle of the output synchronizing signals is almost constant.
