Abstract
An OLED driver for driving at least one organic electroluminescence element, lighting apparatus equipped with the driver and an adjustment method of the apparatus. The driver has a square-wave voltage source and a controller. The source generates square-wave voltage and applies the voltage to the element. The controller controls the source so as to change the frequency of the voltage to change and adjust light output of the element.
