Organic electroluminescence display
First Claim
1. A display unit including a screen on which plural pixels each having an OLED device are arranged in a matrix, which measures a property of the OLED device at a predetermined time interval to reflect a change in the property of the OLED device in an image signal,wherein the change in the property of the OLED device of a subject one of the plural pixels is obtained by comparing between the property of the OLED device of the subject pixel and the property of the OLED device of another pixel, which exist on a same scanning line.

Abstract
The voltage-current property of the specific pixel is measured to store the data on a single line in a line memory. The property data of adjacent pixels are compared. A failure determination unit detects whether or not the pixel to be compared is faulty. If it is determined as being faulty, the faulty pixel is removed from the pixel group to be compared. The burn-in determination unit performs the comparison using normal pixels only to provide the correct burn-in data. The calculation unit reflects the burn-in data in the image data from the host.
