Display Control
PS1D0:
When PS1D0 = 01, only the upper eight raster-rows (COM1DCOM8) are fixed-displayed in vertical
smooth scrolling, and the other display raster-rows are smooth-scrolled. When PS1D0 = 10, the upper 16
raster-rows (COM1DCOM16) are fixed-displayed. When PS1D0 = 11, the upper 24 raster-rows (COM1D
COM24) are fixed-displayed. For details, see the Partial Smooth Scroll Display Function section.
DHE:
When DHE = 1, the double height between raster-rows specified in the Double-height Display
Position section is displayed. For details, see the Double-height Display section.
GS:
When GS = 0, the grayscale level at a weak-colored display (DB = 01) is 1/3. When GS = 1, the
grayscale level at weak-colored display is 1/2, and at strong-colored display (when DB = 10) it is 2/3.
REV:
Displays all character and graphics display sections with black-and-white reversal when REV = 1.
For details, see the Reversed Display Function section.
D:
Display is on when D = 1 and off when D = 0. When off, the display data remains in the CGRAM, and
can be displayed instantly by setting D = 1. When D is 0, the display is off with the SEG1 to SEG128
outputs and COM1 to COM128 outputs set to the GND level. Because of this, the HD66750/1 can control
the charging current for the LCD with AC driving.
