EXPANSION FUNCTION
HOW TO USE EXPANSION MODE
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 of expanding vertical direction as shown in Table 1. And expanding horizontal
direction is possible by setting input CLK frequency which is equivalent to the magnification. It is necessary to make
this CLK outside of this LCD module.
The below image is display example, when DE function is default and HD and VD is set to most suitable frequency.
And when DE function is used, HD and VD become default. Adjustment the display to the best position by DE signal.
Please adopt this mode after evaluating display quality, because the appearance of expansion mode is happened
to become bad some cases.
Notes 1. See more detail on Color control function and graph image.
