LCD DRIVE CONTROL CIRCUIT
The 7560 group has the Liquid Crystal Display (LCD) drive control
circuit consisting of the following.
LCD display RAM
Segment output enable register
LCD mode register
Voltage multiplier
Selector
Timing controller
Common driver
Segment driver
Bias control circuit
A maximum of 40 segment output pins and 4 common output pins
can be used.
Up to 160 pixels can be controlled for LCD display. When the LCD
Fig. 46 Structure of segment output enable register and LCD mode register
enable bit is set to
“
1
”
(LCD ON) after data is set in the LCD mode
register, the segment output enable register and the LCD display
RAM, the LCD drive control circuit starts reading the display data
automatically, performs the bias control and the duty ratio control,
and displays the data on the LCD panel.
