Usage exceeding absolute maximum ratings may permanently impair the LSI. Normal operation should
be conducted under the recommended conditions. Exceeding those conditions may adversely affect the
reliability of the LSI.

Remarks
1
The optimal value depends on the characteristics of the used LCD element. Also, the LCD bias voltage is
biased to 1/3 the supply voltage by the resistor of approximately 20k
in the LSI.
