Abstract: The invention more particularly relates to a method and device for controlling a segmented electrophoretic display. Such displays, preferably covered by the invention, comprise a layer (or a film) of microcapsules containing colored particles suspended in a fluid or a gas, the same layer being sandwiched between two electrodes: at least one first electrode having the shape of the segment to be displayed a second transparent electrode made by a conductive layer of indium tin oxide (ITO) for example. Alternative electrodes based on a thin film of carbon nanostructures, silver or copper wires can also be used.

Abstract: Method for producing an electrophoretic display device comprising a low-voltage microcontroller. The invention relates to a method for producing a segmented electrophoretic display device comprising a bistable display operating at predetermined opposing voltages and an electronic circuit with microcontroller for controlling the display according to a control program. The method includes the following steps: supplying the controller, which is different from a specific display controller for a bistable display and configured to deliver voltages, lower in absolute value to the predetermined voltages, and compensating the voltages with at least one compensation voltage to at least reach the predetermined opposing voltages. The invention also relates to the corresponding device.

Abstract: This invention relates to a method to compensate by a server a clock deviation of a card i by maintaining a time base Tbase (i) synchronized with card i, the method comprising the steps of: receiving at a time TS a dynamic card verification dCVV code value generated by card i; providing a set of at least two dCVV code corresponding to two successive dCVV time periods; if the dCVV code received from card i corresponds to one of the dCVV codes of the provided set but is different from the reference dCVV code, determine the minimum possible timing drift Min_td between the time base maintained by the server for the card and the time base Tbase(i) of the card; updating time base Tbase(i) by addition of a time drift correction equal to the minimum possible time drift Min_td.
