Organic electroluminescence display device manufacturing method and organic electroluminescence display device
摘要:
A method of manufacturing an organic electroluminescence display includes preparing a substrate including pixels. The pixels each include a drive transistor and a capacitor. The capacitor of a subject pixel is caused to hold a voltage which corresponds to a threshold voltage of the drive transistor, and the voltage is read. A first signal voltage is obtained by adding a first correction parameter of the subject pixel to a second signal voltage corresponding to a single gradation level belonging to an intermediate gradation region or a high gradation region of representative voltage-luminance characteristics. The first signal voltage is applied to the driver of the subject pixel, and a luminance emitted by the subject pixel is measured. A second correction parameter with which the luminance emitted by the subject pixel becomes a standard luminance is calculated.
