Sumitomo Chemical has worked on developing a technological lead on smartphone touch displays recently introducing their bendable touchscreens as they prepare to manufacturer over 100 million annually. Static electricity stimulates the organic light-emitting diode (OLED) built inside smartphones display screens. If you want to learn how organic light-emitting diode, a brief video is posted below that explains the technology that the Japanese have excelled in developing. Organic material means any compound that is carbon-based. It is probably from the petrochemical industry where the compounds are extracted to create the raw ingredients that go into the OLED displays. It’s just too bad Japan-based Sumitomo employees won’t be able to benefit much from this manufacturing. After reading the article readers will find out why.

Sumitomo Chemical to triple capacity for bendable touchscreens
Growing adoption of OLED displays in smartphones emboldens Japanese company
TOKYO — Sumitomo Chemical intends to triple its manufacturing capacity for flexible touchscreens used in next-generation smartphone displays to over 100 million annually by the start of 2018.
The Japanese company already dominates touchscreens for organic light-emitting diode displays in smartphones, supplying 60-70% of global demand.
The touch-detection circuitry for the bendable screens is fabricated on plastic films instead of glass substrates. Being lighter than glass, these plastic touchscreens are easier to handle in the production process. Being bendable, they give smartphone makers greater design flexibility.
Sumitomo Chemical plans to invest roughly 15 billion yen ($132 million) to boost output by re-purposing a production line at its liquid crystal display materials factory in Pyeongtaek, South Korea.
