Abstract
The invention relates to a novel display system for a drug delivery device that reduces power consumption and permits the user of the device to see messages when the device is not in a powered state or when the device has encountered an error condition. By using a bistable display, the medical device is able to maintain messages that can been seen by the user even when the device's power supply is exhausted or when the device has encountered an error that interrupts its normal operation. The use of such a display also improves the battery life by eliminating the need to provide power to the display screen when it is not being updated.
