As an example, a SVGA resolution LCD panel has 800 pixels horizontally by
600 pixels vertically. Input video is also represented by the same terms. XGA
input video has a format of 1024 pixels horizontally by 768 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.
