qFX
Denes the size of the character eld in the X direction (i.e., size of one character including a
space).
Structure of the character eld
1. Because the S1D13700 processes the display data in 8-bit units, if the character font exceeds 8 bits, the
text screen must congure one character with two or more display memory addresses as normally prac-
ticed. In this case, odd-numbered bits less than a unit of 8 bits are not displayed as shown below. Odd-
numbered bits less than a unit of 8 bits are also not displayed on the back-layered screen as shown below.
2. In graphic display mode, the character eld must normally be 8 bits long. For other character elds, odd-
numbered bits less than a unit of 8 bits are not displayed.
Figure 3-2 Typical relationship between FX/FY and display addresses
In grayscale mode, FX must be xed to ‘00111’ (8 dots).
qWF
Species the AC drive method of the liquid crystal.
WF
0: Line inversion drive method
1: Two-frame AC drive method (method B)
The two-frame AC drive method is an AC drive method in which the half period of the WF
signal constitutes a one-frame interval. Normally, set WF = 1.
The line inversion drive method is a modied AC drive method in which the WF signal has its
waveform inverted every 16 Y lines.
Note: Although the LCD may look better when WF is set to 0, stripes in the X direction
will appear when the LCD drive voltage is high or viewing angle large.
