menic pro LCD

[Snail Instruments]

>Zkuste mi nekdo prosim poradit co nejmensi a co nejlevnejsi (rozsah 1xIO,
>nebo 3 tranzistory - pokud mozno) menic 5VDC/-10VDC pro LCDisplay.

Otazka je, jestli bude opravdu potrebovat zapornejsi napeti, nezli -5V.
Kdyby nahodou nepotreboval, staci 7660, menic +5V -> -5V, jinak 7661(?),
+5V -> -10V.
