Summary[edit]
DescriptionCharlieplexedArray2.png |
English: The diagrams show 6 (n) conductive elements which cross each other , forming 36 (n^2) intersections. LEDS are shown placed at every intersection . Where a LED joins one conductor to itself ( e.g. where LED D5 joins conductor 2 to itself ) , those 6 (n) LEDS will never light , as a voltage can never develops across them . There is, therefore, no point in putting them in.
Reverse polarity LEDS join every possible combination of conductor pairs . These LEDS are called complementary pairs. This allows all the other ( n^2 - n ) LEDS to be uniquely addressable, and they can all be lit independently . For example, when conductor 3 is positive and conductor 2 is negative, current flows through, and lights up LED D8, but when conductor 3 is negative and conductor 2 is positive, current flows through, and lights up LED D9. This diagram has 15 complementary pairs, allowing 30 LEDS to be lit independently . |
