How to turn of the tft display.

Hi. i use a IM120419006 tft here i would like turn off the display with code or if its not possible i would like use the blacklight. i use utft library and i write lcdoff comand but it dont work.

I try to put the tft pins to high o low but not work. How i can turn off the tft? thanks

Usually the backlight is not handled by the TFT controller. So you have to do both: Power down the controller and turn off the backlight with an external MOSFET (e.g. IRLU120).


ok thank you very much oliver. i try to remove the shield. thanks
