Abstract
The disclosure relates to driving methods for bistable displays, in particular, driving methods comprising interleaving driving waveforms.
Claims20
A driving method for driving a first group of pixels from a first color state to a second color state and a second group of pixels from the second color state to the first color state in a display device, which method comprises applying interleaving uni-polar driving waveforms.
A driving method comprising a soft drive phase, a full drive phase and interrupting driving signals, which method comprises applying said interrupting driving signals between the soft drive phase and the full drive phase or during the full drive phase.
A driving method for driving pixels to a state between a first color state and a second color state, which method comprises applying interleaving uni-polar driving waveforms.
A method implemented in an electrophoretic display device, comprising:
- a display device applying, to each pixel of the display device of a first group of pixels that are in a white color state, a first positive voltage at a common electrode and a first no voltage at each of a plurality of pixel electrodes coupled to pixels of the first group, during a first time period;
- the display device applying, to each pixel of the display device of a second group of pixels that are in a dark color state, the second no voltage at the common electrode and a second positive voltage at the pixel electrodes coupled to pixels of the second group, during a second time period after the first time period.
