Sony has unveiled an OLED display that can be repeatedly wrapped around a pencil and still produce moving images. The electronics giant revealed its Organic Thin-Film Transistor (OTFT) driven display at the Society for Information Display’s event held last week in Seattle, USA. Sony claims the 80 micrometre thick display has shown no degradation after being rolled and stretched 1,000 times.
Development of flexible organic displays is a priority for Sony, which says it expects
the application of its research to yield thin, lightweight, durable and mobile devices.
In order
to enhance flexibility of the display, Sony has developed organic insulators for all the insulators
in the OTFT and OLED integration circuit. These organic insulators can be formed with the
solution process in the atmosphere which is requires fewer steps, and consumes materials and
energy more efficiently - thus has a smaller environmental footprint - compared to the conventional
high temperature vacuum semiconductor process which use inorganic/silicon materials.
The SID International Symposium, Seminar and
Exhibition brings together scientists, engineers, manufacturers, and users in the electronic-display industry. This year it
was held from May 23 – May 28, 2010 at the Washington State Convention Center, Seattle, USA.
