As an example, a SXGA resolution LCD panel has 1280 pixels horizontally by 1024 pixels vertically.
Input video is also represented by the same terms. SXGA input video has a format of 1280 pixels
horizontally by 1024 pixels vertically. When the input pixels contained in the video input format
match the native resolution of the panel, there is a one to one correspondence of mapping of input
video pixels to LCD pixels. As an example, the pixel in column 45 and row 26 of the input video is
in column 45 and row 26 of the LCD. For the case when the input video is at a lower resolution
than the native resolution of the LCD, the direct correspondence between the video pixels and the
LCD pixels is lost. The LCD controller can compute the correspondence between video pixels and
LCD pixels using algorithms contained on its controller. The accuracy of the algorithms determines
the fidelity of conversion of video pixels to LCD pixels. Poor fidelity conversion can result in
artifacts in the LCD displayed image such as varying width characters.
