Electrowetting display device control method

摘要

A method of controlling an electrowetting display device with display elements arranged in a matrix with n rows. In examples each display element is addressable with a voltage pulse having a pulse duration longer than Tf/n, where Tf is a pre-determined frame period for addressing the n rows. In examples the pulse duration may be longer than ReCe, with Re being an electrical resistance of an electrically conductive fluid of a display element and Ce being an electrical capacitance of a capacitor of the display element.

1. A method of controlling an electrowetting display device comprising display elements arranged in a matrix having n rows, n being larger than one, each display element of the display elements having a corresponding switching element, the method comprising:
determining a value for a first pulse duration corresponding to a voltage pulse to be applied to the corresponding switching elements of each display element of the display elements in at least one of the n rows, the first pulse duration being longer than Tf/n, Tf being a pre-determined frame period for addressing the n rows; generating the voltage pulse having the first pulse duration; transmitting the voltage pulse to the corresponding switching element of each display element of the display elements in the at least one of the n rows; and applying substantially simultaneously with the voltage pulse at least one reset voltage to the display elements in the at least one of the n rows to reset the display elements in the at least one of the n rows to reduce backflow, backflow being a tendency of a first fluid and a second fluid of each display element of the display elements in the at least one of the n rows, during application of a voltage to the display elements in the at least one of the n rows, to flow back to a configuration of the first fluid and the second fluid where no voltage is applied.
