employing polymers
driven with passive-matrix (such as PMOLED)
each row (and line) in the display is controlled sequentially, one by one
driven with active-matrix (such as AMOLED)
thin-film transistor backplane to directly access and switch each individual pixel on or off
higher resolution and larger display sizes
