• Boosted output voltage should not exceed the maximum value (13 V) of the LCD driving voltage.
Especially, a voltage of over 4.3V should not be input to the reference voltage (Vci) when boosting three
times.
• A voltage of over 5.5V should not be input to the reference voltage (Vci) when boosting twice.
• The value of resistance, according to the number of lines, duty ratio and the bias, is shown below.
