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.
