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 con-
tained 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 or higher 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 pix-
els 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. P oor
fidelity conversion can result in artifacts in the LCD displayed image such as varying
width characters.
