Q. What is going on with the backlight on this?
Data is via the standard 14 pin connector, there are no pins for the backlight.
There is one, I now have it lit, but I had to wire it up directly onto the LED with a current limiting resistor. There are a lot of unpopulated components around the backlight section. Not sure what the plan was, but it's not ideal having to bodge power to the backlight .
A. Hi Dave. Thank you for your question. The backlight is powered directly onto the led via a resistor. The manufacturer states exactly that the same board is used for their OLED screens and the missing components are fitted only on the OLED versions. See the data sheet for backlight information.

Simple to use, great value display

These displays use a Hitachi HD44780 compatible on-board driver and have standard pin-out, making connection to a microcontroller really simple. There's loads of information and coded examples for using displays of this type. The display gives a high quality output, the white text on blue is particularly striking. Contrast is adjustable and viewing angles are respectable, though, as usual with LCD, don't expect fast response times (the Winstar OLED version of this display will be a good choice if very fast updates are needed). Overall, this display is simple to use and great value for money.
