14. EXPANSION FUNCTIONS
Expansion mode is a function to expand screen. For example, VGA signal has 640×480 pixels. But, if
the display data can expanded to 1.6 times vertically and horizontally, VGA screen image can be
displayed fully on the screen of XGA resolution.
This LCD module has the function that expands vertical direction as shown in 7.9 (1). And expanding
horizontal direction is possible by setting input CLK frequency equivalent to the magnification. It is
necessary to make this CLK outside of this LCD module.
Please adopt this mode after evaluating display quality, because the appearance in expansion mode is
happened to be relatively bad in some cases.
The followings show display magnifications for each mode.
