A driving system and method for electroluminescence displays having a
matrix of electroluminescence elements arrayed in rows and columns with a
control circuit for discharging each anode line to a column equalization
bus (CEB), includes connecting the charged anode line to the CEB at the
end of activation of each anode line. Discharging and subsequent
de-activation of the anode line are allowed by charge-sharing with
un-activated anode lines that are to be activated for the next row. This
is accomplished by connecting the charged anode line to the CEB. In
displaying images, anode lines are activated for a number of time periods
according to gray scale or color data. Anode lines are consequently
de-activated accordingly at different times during a lighting phase for
each row display time. When anode lines are discharged through charge
sharing on the CEB, a control circuit maintains the voltage on the CEB
below a level that may cause inadvertent activation of the de-activated
elements.
