FIELD: physics.
SUBSTANCE: leads are adapted to connect to a double-wire process control circuit. A power module is connected to multiple leads for receiving electric current from a technological process control circuit. Controller circuits are connected to the power module, and a microencapsulated electrophoretic display is connected to the controller circuits and is configured to display information received from the double-wire technological process control circuit. The controller circuits and the microencapsulated electrophoretic display are powered from the double-wire technological process control circuit.
EFFECT: designing a novel microencapsulated electrophoretic display for process parameters, which consumes less power and provides very high contrast.
