i have a battery driven circuit.

there are a 2 * 16 lcd and buttons on it.

if it is not using , i use the sleep mode for low power consumption.

until new data comes , pic is in sleep mode.

there is no problem about the pics' entering sleep mode or wake up

the problem is ; i have turn off the lcd for power consumption if pic is in sleep mode.

i have tried to enable and disable the supply of lcd.but the current of the lcd does not decrease.

i have to turn off the lcd in order to turn the circuit into low power consuption

i use 18f1320 in intrc osc 4MHZ , lcd is in 4 bits - bus mode


i will be glad to hear your ideas about this problem
