Abstract
An electroluminescence display is composed of an electroluminescence pixel and a driving circuit. The driving circuit drives the electroluminescence pixel to emit light. The driving circuit provides a first drive current, and then provides a second drive current for the electroluminescence pixel. The first drive current is larger than the second drive current, and increases depending on the second drive current.
