Abstract
3D is coming to the home, and there are several ways it can be viewed. For direct view flatscreen TV displays, there are two competing technologies available (LCD and plasma), with a third (OLEDs) waiting in the wings. Each of these display technologies has its strengths and weaknesses when showing 3D images. — LCD technology, which is widely used for consumer TV designs, provides bright pictures under normal room lighting, but has difficulties with fast motion and 3D crosstalk. Optimum viewing angles are restricted for 3D LCD TVs. TV manufacturers are moving away from traditional CCFL backlighting to light-emitting diodes to provide local area dimming, higher contrast, and faster switching speeds. — Plasma displays are well-suited to 3D because of their inherently wide viewing angles, high contrast, and deep black levels. They are largely immune to crosstalk. However, 3D plasma TVs must use different phosphor formulations for active shutter 3D viewing. Plasma technology also uses more power than same-size LCD TVs. — Organic light emitting diodes have been in development since 1987, and may be best suited for 3D TV applications. However, there are still issues with brightness and color uniformity and organic color material lifetime that will be challenging to overcome if OLED TVs are to come to market.
