Abstract

This paper presents precise measurement system for the lifetime of OLED. The proposed system collects the data for using voltage drop across the OLED Panels, and then the computer program makes an analysis of the data. In this process of measurement, the current across OLED material must be amplified because the current is very small. However, amplifying the current causes the amplification of noise. Therefore, the proposed system measures the current using an algorithm which minimizes the noise.
