Abstract
A driving circuit for an electro-luminescence (EL) cell includes an EL cell, and a supply circuit selectively applying current to the EL cell based on a pixel signal from a data line. A control circuit controls current flow from the supplying circuit to the EL cell such that an amount of current for discriminating between gray scale levels is approximately tens of micro-amps.
