a) connection example of power supply
Be cautious of using as following description when LCD panel is connected with master/slave structure.
1) Display timing is controlled by master chip. The CL, FLM, FR, CLK signals are stopped when master
chip is display OFF. When you are going to OFF the display, please OFF the display of slave chip first
before master chip display is OFF.
2) Boosting circuit and voltage converting circuit is OFF after execution HALT command at master chip,
then LCD driving output is V
SS
level and so display is OFF. And Voltage common is stopped. Because
the voltage common of slave chip is stopped, please run slave chip display OFF first and then run master
chip HALT command.
3) The electric volume setting is valid at master chip only(at upper structure).
4) To protect that V
OUT
is being floated, please connect V
OUT
with V
LCD
voltage level.
5) Please use under condition that OSC
1
and OSC
2
port of slave chip is OFF.
