Low Power LED Backlight for 0216K1Z
Hi,
The K1Z series of the 2x16 characters LCD use a low power side LED backlight. However, there is a 100R resistor between A+ and K-, so we have to use a higher voltage that we have to do if we can choose the resistor or the current regulator circuit.

Have you plan to set this internal resistor to 0R in future ?
Thanks

The resistor on the PCB is in place to currently limit the backlight. If you wish to use higher voltage, you may either replace this resistor with a larger value, or use an external series resistor on the line going to pin 15.
We do not have plans to come out with a version with a 0 ohm resistor there, however, if you are interested in purchasing these displays with a 0 ohm resistor we do offer custom displays and value add services. To investigate this option further, please email us nhtech@newhavendisplay.com
