long term stability)
- Pulse should be short, to avoid flicker
- Long enough for the black-black transition
White pixel (black-white transition)
- Starts at the beginning. Looks like a black pulse is not required.
- White low level must stop before the black pixel are finished
Black pixel (black-black and white-black)
- Black (high level) is extended. If the black level is applied longer, the contrast
gets better.
- There must be no white pixel write otherwise contrast will be bad: Writing
black is put at the end and starts in the middle
