My LCD had build-on negative invertor (-16V)

Is that your LCD ?

So you got all dark display or nothing at all ?

Maybe if you presented all your connections here we could check if there was anything that might be wrong.

nothing at all

I'm check my connctions, but it don't wrong ....

LPT LCD
1 5(WR)
2 11(DB0)
3 12(DB1)
4 13(DB2)
5 14(DB3)
6 15(DB4)
7 16(DB5)
8 17(DB6)
9 18(DB7)
14 7(C\E)
16 8(C\D)
17 6(RD)

+5V 3(Vdd),19(FS),10(RESET)
GND 2(GND)
--------- 9(Vee)

10K <------4(Vo)

-------- GND

If you can't even adjust contrast you might not have enough contrast voltage. You could try connecting the other end of the contrast potentiometer to +5V instead of GND.

How about the REVERSE pin ? Try connecting it to +5V or GND.

Now I can adjust contast !!! I'm connect 20pin(REVERSE) to +5V and it work !!! But I'm see garbage on my screen ( i mean my LCD connecting wrong ? )
maybe connect LCD like this :

LPT -> LCD
1-----7(C\E)
2-----11(DB0)
3-----12(DB1)
4-----13(DB2)
5-----14(DB3)
6-----15(DB4)
7-----16(DB5)
8-----17(DB6)
9-----18(DB7)
14-----6(RD)
16-----5(WR)
17-----8(C\D)

+5V------3(Vdd),10(RESET),19(FS),20(REVERSE)
GND-----2(GND),1(FG)
