ABSTRACT:
A drive system is provided for a thin-film EL display panel which includes and EL thin layer sandwiched between a pair of dielectric layers, a plurality of scanning line electrodes formed on one of the dielectric layers, and a plurality of data line electrodes formed on the other of the dielectric layers. The scanning line electrodes and the data line electrodes, in combination, define a matrix pattern. Scanning pulses are sequentially applied to the scanning line electrodes, and a data sugnal is applied to the data line electrode which includes a selected picture point where the data line electrode crosses the scanning line electrode which is receiving the scanning pulse. Scanning line electrodes which are not receiving the scanning pulse are connected to receive a voltage signal of which a level is below the threshold level of the light emission.
