Nokia 5110 LCD sleep mode.

Hello i was wondering if there was a way to put the Nokia 5110 LCD to sleep some kind of turn off to save power if not in use? and have it wake up it any button is pressed?

you can switch off its power supply .... controlled through a digital pin a resistor and transistor ...

i try to disconnect the vcc pin and the backlight stayed on dim then i try to disconnect the backlight pin and the lcd stayed oni can see the text.

maybe you should disconnect both of them with a transistor…

this is how i have it pined out

D6 - RST
D7 - CE
D5 - DC
D4 - DIN
D3 - CLK
3.3v - VCC
GND - Back LIGHT
GND - GND

i have seen some pinout images with resistors I'm not sure why mine i do not have them.
