摘要： An OLED driver possesses a square-wave voltage source, a controller and a detector. In accordance with first control, the source generates square-wave voltage and applies the voltage across at least one organic electroluminescence element to drive the element. The controller controls the source in accordance with the first control. The detector detects equivalent capacitance inherent in the element. The controller also judges whether or not the element is normal based on the equivalent capacitance. If the element is normal, the controller operates in accordance with the first control. If the element is not normal, the controller operates in accordance with predetermined second control for the element which is not normal.
