Abstract
An electroluminescent display device and a method of compensating for electrical characteristics of the electroluminescent display device are disclosed. The electroluminescent display includes a storage memory storing an average current-voltage expression of a display panel and a current value for each pixel, a parameter calculation unit calculating an offset and a gain for each pixel for causing current characteristics for each pixel based on the current value for each pixel to coincide with average current characteristics based on the average current-voltage expression, and a data correction unit correcting input image data to be written to each pixel based on the offset and the gain for each pixel. The average current-voltage expression and the current value for each pixel are obtained through a camera-based sensing process.
