Digital Fabrication for OLED Display

抄録

OLED attracts attention as next-generation display technologies, and products manufactured by the vacuum deposition method are already penetrating the market. Digital fabrication, which manufactures this OLED display using inkjet, is a key technology that significantly reduces manufacturing costs.

In this paper, the structure of the OLED display is explained, and the features of the technology and products are stated. The features of several manufacturing methods of OLED display are explained.

Striped light emission unevenness due to variation in ink amount which was a problem of the inkjet method was solved by new techniques. As a result, OLED displays manufactured by the inkjet method have become available. An ink jet apparatus capable of massively manufacturing a large-sized OLED display at a low cost is nearing practical use. It is expected that the spread of OLED display will accelerate.
