Patent ID: 8553052

Claim:
A display device, said display device further comprising: a plurality of display elements arranged in the shape of a bar, and wherein each one of said plurality of display elements can represent at least one first display state and one second display state; a value being shown by said display device can be indicated by said second display state utilizing at least one display element assigned to said value, and an intermediate value between said value being displayed and a succeeding or a preceding value can be represented by activating a corresponding preceding or a corresponding succeeding display element; an actuation circuit; wherein said actuation circuit allows: a first current strength actuates said first state; a second current strength actuates said second state; and a third current strength actuates said third state; while said third current strength lies between said first current strength and said second current strength; said actuation circuit comprising: a microprocessor having one output each for actuating each display element, said microprocessor further comprising: a first output state; a second output state; and a third output state; and an input circuit for each of said display elements, said input circuit further comprising a transistor, whose base is connected to the output of said microprocessor and across a first resistor to a power supply voltage, whose collector is connected across a second resistor to said power supply voltage, while an emitter is connected to ground across a series circuit of a third resistor and a light emitting diode as said display element.
