What''s new in digital displays?

摘要

Flexible displays using plastic film substrates are key devices for ubiquitous and universal services of digital broadcasting because of their mobile characteristics, low-cost productivity, and flexibility of viewing style. Polymer organic light-emitting devices (POLEDs) and ferroelectric liquid crystal (FLC) films composed of FLCs and polymer networks are promising display devices and materials for the reproduction of TV images in which gray-scale and high-speed response characteristics are required. Both prototype flexible displays of POLED and A4-sized FLC have been fabricated using phosphorescence materials. Performances of these displays showed substantial potential for ubiquitous and universal digital broadcasting services.
