    摘要： A display LED drive circuit is configured as follows. For example, a constant current circuit, a green display LED circuit, and a red display LED circuit are connected in series and a resistor circuit having a resistor causing a potential difference identical to each of the display LED is connected in parallel to each of the LED circuits. A corresponding switching element of the display LED circuit and a corresponding switching element of the resistor circuit connected in parallel are controlled to be opened and closed in opposite ways. Another route connected to a source circuit in parallel is connected to a constant current circuit, a blue display LED circuit, and a constant voltage diode in series. The blue display LED circuit is connected in parallel to a resistor circuit as has been described above. A predetermined voltage is taken out from the output terminal by the constant voltage diode and supplied to a control circuit. Thus, it is possible to reduce the number of constant current circuits, current consumption, and the cost, thereby improving the power source use efficiency.

    摘要： A display LED drive circuit configured in such a manner that, for example, a constant current circuit, a green display LED circuit, and a red display LED circuit are connected in series and a resistor circuit having a resistor that generates a potential difference identical to the respective display LEDs is connected in parallel to the respective LED circuits, a corresponding switching element of the display LED circuit and a corresponding switching element of the resistor circuit connected in parallel are controlled to be opened and closed in opposite ways, another route connected to a source circuit in parallel is connected to the constant current circuit, a blue display LED circuit connected in parallel to the resistor circuit as described above, and a constant voltage diode in series, and a predetermined voltage is derived from an output terminal by the constant voltage diode and supplied to a control circuit. In this arrangement, the number of constant current circuits can be reduced, and hence reduction of current consumption and cost, and improvement of the power source usage efficiency are achieved.

    摘要： A voltage controlled display is described. The voltage controlled display is a low voltage display and has a display element having a pair of electrodes and a voltage divider having a terminal coupled to a first one of the pair of electrodes of the voltage controlled display. A metal-insulator-metal diode having a switching voltage less than about 10 volts coupled to the voltage divider. In a preferred embodiment, the display element further includes a second metal-insulator-metal device and wherein the voltage divider includes a resistor coupled in series with the second metal-insulator-metal diode.
