LCD pin names

We have this LCD and we are trying to connect it to the Arduino. We are having problems with the pin names. Here's what we have so far:

Vss - ground

Vcc - voltage (+)

VLc / Vee - we believe this one is for contrast - confirmed

RS : register select

R/W :read / write


D0-D7 : data pins

VB+ : LED positive

VB- : LED negative

R/W = read write it tells the lcd which mode to be in (read or write )

E = enable, either high or low to turn the lcd on, it depends on the lcd
