Net Energy/Full Cost Accounting: A Framework for Evaluating Energy Options and Climate Change Strategies

In one embodiment of the present invention, a first diode is connected between two elements of a seven-segment display character. A second diode is also connected between two elements of the seven-segment display character. With the diodes so connected, the seven-segment display character can display the characters "1" through "9", and can do so with only six of the seven segments coupled to display driver circuitry. Electronic resources are thus saved in the control of the seven-segment display character.
