摘要： PURPOSE:To obtain the aging method of an EL panel having a short processing time and a sufficient effect. CONSTITUTION:In the aging method of an EL panel, the first and second periods are set, and the first and second periods are repeated at the fixed cycle. The first period consists of the first field when the picture elements formed by transparent electrodes 2 and the first metal electrode groups 6A are illuminated by the positive voltage applied to the transparent electrodes 2 and the second field when the picture elements on the first metal electrode groups 6A are illuminated by the negative voltage applied to the transparent electrodes 2. The second period consists of the third field when the picture elements formed by the transparent electrodes 2 and the second metal electrode groups 6B are illuminated by the positive voltage applied to the transparent electrodes 2 and the fourth field when the picture elements on the second metal electrode groups 6B are illuminated by the negative voltage applied to the transparent electrodes 2.

摘要： PURPOSE:To realize a light controlling function extending over a wide range without deteriorating the quality of a display screen by applying a write voltage, and thereafter, applying a light controlling pulse voltage whose polarity is opposite to that of said write voltage to a scanning side electrode. CONSTITUTION:By varying a variable voltage from a variable voltage generating means 7, a third DC voltage VW+VM and a modulation voltage VM are varied, a voltage applied to an EL layer is varied and a light control is executed. Also, a write voltage is applied by a write voltage applying means 5, and thereafter, a light controlling pulse voltage whose polarity is opposite to that of the write voltage is applied by a light controlling pulse applying means 6. The light controlling pulse voltage is a first DC voltage VW or a second DC voltage 1/2 VW, therefore, even if the variable voltage is varied in order to execute a light control, the light controlling pulse voltage is not varied. In such a way, a light controlling level can be varied without deteriorating the quality of a display screen of the EL layer.
