LED Backlight

Standard display EA DIPS082-HN is reflective, non-backlighted version. Module with part number

EA DIPS082-HNLED comes with yellow/green LED backlight. Power consumption for backlight is 50mA

typ. and 80mA max. Backlight is permanent switched on.

For individual use LED backlight can be switched on and off after doing the following modification:

Remove series resistor R5 and change resistor from R6 to R7. Now a positive voltage at pin 7 (D0)

powers Anode of backlight direct. To limit LED-current an external series resistor is required (R
