Abstract
In a bistable display device having a driver circuit, the driver circuit has multiple electrical ports for electrically connecting to external circuits. The electric potential difference between any two neighboring ports is less than 10 volts so that electrical punch-through caused by great electric potential difference and short distance between the electrical ports is substantially avoided.
