Precautions
The data for electrical characteristics, reliability and lifetime expectancy has been based on typical driving conditions. When designing circuitry, apply the typical rate of driving voltage or, if the voltages fluctuate, the minimum and the maximum values of the driving voltage should be set within specified ratings.
Exceeding any of the maximum ratings may cause damage to the display, or driving below minimum ratings may cause insufficient brightness. Displays used under anything other than specified conditions will be defined as out of warranty.
