There are four methods to light up the LED back-light : (Please indicate while ordering.)
(1) Built-in current-limit resistor(R9/R10). Add +5V between Pin15&16. (Default)
(2) Add +4.05V between LED A & K directly.
(3) Short JP2 and add +4.05V between Pin15&16.
(4) Built-in current-limit resistor(R9/R10) and short JP1&JP3. Use the same power (+5V) with
the logic circuit.
