Patent attributes
A method for driving an electro-optic display having a front electrode, a backplane and a display medium positioned between the front electrode and the backplane, the method comprising of applying a first driving phase to the display medium, the first driving phase having a first signal and a second signal, the first signal having a first polarity, a first amplitude as a function of time, and a first duration, the second signal succeeding the first signal and having a second polarity opposite to the first polarity, a second amplitude as a function of time, and a second duration, such that the sum of the first amplitude as a function of time integrated over the first duration and the second amplitude as a function of time integrated over the second duration produces a first impulse offset. The method further comprising applying a second driving phase to the display medium, the second driving phase produces a second impulse offset, wherein the sum of the first and second impulse offset is substantially zero.
