[Parameter P2]
Structure of the character field
1. Because the S1D13700 processes the display data in 8-bit units, if the character font exceeds 8 bits, the

In grayscale mode, FX must be fixed to ‘00111’ (8 dots).

text screen must configure 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.

Defines the size of the character field in the X direction (i.e., size of one character including a
space).
Specifies the AC drive method of the liquid crystal.
WF
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 modified 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
