Abstract
An electroluminescence display and a method of managing defective pixels thereon are provided. Defective pixels are detected from the pixels, based on sensing results on the electrical characteristics of a driving element, and defect candidates are selected from among the pixels within a compensation range in which the electrical characteristics of the driving element can be compensated by a compensation value obtained based on the sensing results on the electrical characteristics of the driving element.
