Power consumption(measured with random texts)
2.5V
20(typical)
50mW
3.0V
45(typical)
63mW
Note:1.When random texts pattern is running,averagely,at any instance,about 1/4 of pixels will be
on.
2.If VBT is not operated within 2V and 3V,non-uniformity display may occur.
3.You have to use the saving mode by VBT 2.5V in order to make long life.
