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.
