DRIVER DI CORRENTE PER UN ARRAY DI DIODI LED. |
摘要 |
An array of LED diodes includes N channels each having LEDs coupled in series with a switch. A current driver for the array includes a processing circuit configured to detect N currents flowing respectively through the N channels of the array. The detected currents are converted by a single analog to digital converter, one at a time, into a digital word. The circuit further includes N comparator devices configured to control the N switches as result of a comparison between the digital words and respective target digital words. A memory is provided for storing the digital words received from the analog to digital converter. |
