Lcds, Leds, Oleds, And Epds Light The Way

摘要

Display technologies continue to march forward, with LCDs, LED displays, organic LEDs (OLEDs), and electrophoretic displays (EPDs) leading the charge. LEDs and OLEDs may even overtake LCDs for some applications, while EPDs carve out a niche in electronic-ink displays for portable and flexible electronic products. Nonetheless, LCD applications are flourishing and becoming more diverse, requiring equally diverse design challenges to meet different performance requirements. NEC Electronics America foresees important industrial and medical applications that require innovative approaches to satisfy various demands. Topping the list are the needs for portability, low power consumption, ruggedness, energy efficiency, environmental friendliness, and the ability to operate in variable lighting conditions both indoors and outdoors. LCDs are still used in all kinds of products, large and small, despite a downward revision of market size as price erosions affect profits. For example, LCD 14-, 15.4-, 7-, 19-, 22-, 32-, and 42-in. panels are reportedly being sold at cost and sometimes at a loss. Despite this, LCD TV shipments are expected to rise 20% this year, up from 18.9% last year.
