Patent ID: 6979944

Claim:
A display device comprising: a convergence and dynamic focus corrector and operation processor which corrects a convergence to adjust a first color image and a second color image to an image of a third color using horizontal and vertical sync signals and controls a focus to converge focuses of portions of a displayed image displayed on central and peripheral portions of a screen using the horizontal and vertical sync signals; a first digital-to-analog converter which converts corrected horizontal signals of the first color, the second color and the third color and a dynamic focus control signal sequentially output from the convergence and dynamic focus corrector and operation processor into analog signals; a second digital-to-analog converter which converts corrected vertical signals of the first color, the second color and the third color sequentially output from the convergence and dynamic focus corrector and operation processor into analog signals; and a multiplexer which selectively switches and outputs the analog signals output from the first and second digital-to-analog converters in response to a selection control signal output from the convergence and dynamic focus corrector and operation processor.
