ea dogs102-6 page 3 electronic assembly reserves the right to change specifications without prior notice. printing and typographical errors reserved. led-backlight 3 different variants are available for individual backlighting: white, amber and a duo-color green/red version. there are 2 separate led paths available for each monochrome backlight that can be switched in parallel or in series to suit the system voltage. this means that most backlights can be run at either 3.3 v or a higher voltage. to operate the backlight, we recommend a current source (e.g. cat4238td) or an external series resistor to limit the current. this can be calculated from r=u/i; you can find the values in the table on the right. to prolong the life of the backlights, we recommend that you use a current source. the operating life of the amber and green/red backlights is 100,000 hours. the life of the white backlight is considerably shorter. we recommend that you dim these or switch 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. if you see black and white pictures on this page but you want to see the colors of the displays, you can download a full- colored version of this document at http://www .lcd-module.de/eng/pdf/grafik/dogs102-6e.pdf ea led39x41-a amber ea led39x41-gr green/red ea led39x41-w white amber ea led39x41-a forward voltage current max. limiting resistor @ 3,3 v @ 5 v connected in parallel 2,2 v 80 ma 15 ohm 36 ohm connected in series 4,4 v 40 ma cat4238 15 ohm white ea led39x41-w forward voltage current max. limiting resistor @ 3,3 v @ 5 v connected in parallel 3,3 v 60 ma 0 ohm 28 ohm connected in series 6,6 v 30 ma use cat4238 green/red ea led39x41-gr forward voltage current max. limiting resistor @ 3,3 v @ 5 v red path (arg/cr) 1,9 v 60 ma 24 ohm 51 ohm green path (arg/cg) 2,0 v 80 ma 18 ohm 39 ohm
