    摘要: Method of driving a matrix-addressed electroluminescent device without deteriorating it. A display data driving voltage is applied to the column electrodes. A line scanning driving voltage is applied to the row electrodes successively. Before the display data driving voltage ceases, the line scanning driving voltage applied to the row electrode acting as a common electrode for all electroluminescent cells in one column is turned off. Thus, these cells are deactivated almost simultaneously. Electric charges remaining on the electro-luminescent cells in this row do not induce spike voltages on other electroluminescent cells. Therefore, deterioration of the electroluminescent cells is prevented. Electric charges produced when the row electrode-driving voltage is turned off flow directly into a power supply for the row electrodes. This power supply is designed to absorb the flowing charges. The potential is prevented from exceeding the power voltage. This protects the row electrode-driving power supply against destruction.

    摘要: An EL display includes first and second EL elements each having an EL photoemissive layer and a pair of electrodes provided on opposite surfaces of the EL photoemissive layer. The EL photoemissive layer of each of the first and second EL elements is enabled to emit light when a voltage applied between the electrodes of the EL element is equal to or greater than a given threshold value. A voltage feed circuit serves to apply a first ac voltage between the electrodes of the first EL element. The first ac voltage has a value being equal to or greater than the threshold value. The voltage feed circuit also serves to apply a second ac voltage between the electrodes of the second EL element in cases where photoemission of the second EL element is required. The second ac voltage has a value equal to or greater than the threshold value. The second ac voltage has a phase different from a phase of the first ac voltage. Furthermore, the voltage feed circuit serves to apply a third ac voltage between the electrodes of the second EL element in cases where photoemission of the second EL element is not required. The third ac voltage has a value smaller than the threshold value. The third ac voltage has a phase different from the phase of the first ac voltage.
