In early March we conducted a 10 day trip to Seoul, to attend the OLED Korea 2019 conference (and a visit to some local display companies). One thing that we noticed during our trip is the adoption of E Ink shelf labels in stores.

We have seen E Ink ESL displays in Samsung retail stores (used to detail the new Galaxy S10 flexible OLED smartphone family), and in supermarkets across town. The ESL displays were used to display price and information (unfortunatly always in Korean) - and were nicely placed.

I have always been a strong believer in e-paper dipslays - these displays offer great looking images coupled with extremely lower power consumption - and the flexibility in usage available only for nonvolatile displays. These solutions can be economical, beautiful and also very environementally friendly.

E Ink Holdings recently said that its ESL sales are growing - and it was great to witness this trend first hand in Seoul. In a recent trip to Switzerland I have also seen similar solutions in grocery stores and I hope this will become more and more popular in the coming years all over the world.
