The data sheet does not say much about the contrast voltage; there are a few (mostly older, I think) displays that need a negative contrast voltage. the circuit described above would not produce the rectangular blocks shown on those displays. there is a data sheet for the qp-5515 here http://www.jaycar.com.au/products_uploaded/QP-5515.pdf
