A study on the spreading characteristics of OCR lamination for flexible OLED

The process of bonding a panel substrate and window cover on a flexible display is a very important technology. In this paper, the degree of optically clear resin (OCR) spread on a substrate was theoretically analyzed using OCR which has many advantages over the conventional optically clear adhesive. To develop this idea, the spread of one drop of resin was interpreted as the effect of vector spreading and applied to an actual situation of resin spread. In addition, we checked the validity of this idea by comparing it with actual experimental results, and through the verification of these results, it was shown that processes using OCR can be easily applied in the future.
