A rear-projection television set in which two different dynamic focusing waveforms are used. The first dynamic focusing waveform is used only to focus an electron beam in a CRT generating the blue component of the picture being displayed. The second dynamic focusing waveform is used to focus the electron beam in the CRTs generating the red and green components of the picture being displayed. In this way, the resulting picture is better focused without flare or blue edging and displays better color uniformity over the entirety of the television screen.

Method and apparatus for correcting color component focusing in a rear-projection television set

A method and apparatus for displaying a video signal is described. A video signal is received representing an image having a first aspect ratio, with the image having a top and bottom edge. An edge modification signal is generated. The image is displayed on a display having a second aspect ratio with the top and bottom edge modified in accordance with the edge modification signal. Accordingly, burn lines are minimized through use of the edge modification signal to reduce brightness levels at the top and bottom edge of the image.

Method and apparatus to minimize burn lines on a display

A method and apparatus for displaying a video signal is described. A first video signal is received representing a first image having a first aspect ratio. The first image is displayed on a display having a second aspect ratio and a display area, with the first image having a smaller area than the display area forming a border area. A second video signal is received representing a second image having the second aspect ratio. A border modification signal is generated. The second image is displayed on the display with the border area modified in accordance with the border modification signal.
