PURPOSE:To reduce to half the number of driving wires connecting driving circuits and LEDs and also reduce the number of connectors by a method wherein a first light-emitting diode end and a second light emitting diode end are opposite to each other in polarity and are connected to an output terminal used commonly by a first driving circuit and a second driving circuit. CONSTITUTION:An end of a first light-emitting diode 1 is opposite in polarity to an end of a second light-emitting diode 2. The two ends are connected to an output terminal 10 commonly used by a first driving circuit 3 and a second driving circuit 4. A control signal 20 turns on the first driving circuit 3 for the activation of the first diode 1 or the second driving circuit 4 for the activation of the second diode 2. In this design, only one wire is required for the activation of two LEDs, which reduces the numbers of driving wires and connectors. This design reduces the dimensions of a device. |
