Thanks for contacting us!
We would like to know if when you refer to the RGB LCD doesn’t turn off when use lcd.noDisplay, is because after using this function, the RGB backlight continues on. Please help us to clarify this.
We have made a test and when we used the function lcd.noDisplay the LCD turn off, but the RGB backlight continues on, so, in order to turn it off we have set the RGB to 0:
const int colorR = 0; const int colorG = 0; const int colorB = 0; lcd.setRGB(colorR, colorG, colorB);
Hope this information helps, and we’ll be waiting for your reply in order to know if this is what you are looking for.
