Теперь они почти сравнялись с красными источниками. Срок эксплуатации до достижения 50% яркости (от первоначальной) составляет 33 000 и 44 000 часов, соответственно, тогда как зеленый может проработать 500 000 часов. Непонятно, правда, каким образом был рассчитан этот показатель, т.к. реально проверить его они не могли. Реальной проблемой становится и поддержание баланса цвета при таком разбросе срока службы.<br /><br />Более эффективны (колонка Efficiency cd/A), с точки зрения отдаваемой яркости на единицу потребления энергии, вновь разрабатываемые материалы, но каков будет их срок службы пока непонятно, т.к. представлены были данные лишь о 95% снижении яркости. <br /><br />Все данные относятся к материалам, наносимым точечным методом (аналог струйной печати). Ожидаемые на рынке OLED телевизоры LG и Samsung изготавливаются более трудоемким и дорогостоящим способом с использованием высокотемпературной технологии и вакуумного испарения. Предполагается, что подобные панели менее эффективны в плане светоотдача/энергопотребление, но должны обладать большим сроком службы.   <br />
