With the amber backlight, there are 3 separate LED paths containig 5 parallel LEDs, that can be switched in parallel or in series to suit the systems voltage. With the white backlight, there are 3 separate LED paths containig 3 LEDs in series. To operate the backlight, we recommend a current source (e.g. CAT4238TD). The duo-color backlight has common anode and two terminals for driving the red and / or the green color. The operating life of the amber and green/red backlights is 100,000 hours. The LEDs of the white backlight are high qualitiy NICHIA LEDs. To achieve the life-time of 100k hours, we recommend dimming or switching them off whenever possible. Important: Do never connect the backlight LEDs directly to a 5 V/3.3 V supply as this will immediately destroy the LEDs. Always use a current source. Please note that derating applies at temperatures exceeding +25C.
