Sharp представляет новые дисплеи типа MEMS04.10.2013 |

Компания Sharp представила на выставке CEATEC 2013 прототипы цветных дисплеев на основе ячеек типа MEMS, которые используются вместо привычных ЖК (жидкокристаллических) ячеек. В отличие от обычных жидкокристаллических панелей, новые дисплеи устраняют потребность в поляризационной пластине, которая вдвое снижает коэффициент пропускания света и цветовой фильтр, который уменьшает его на 1/3. В результате, появляется возможность уменьшить энергопотребление панели до 1/6 части от показателя обычной ЖК панели. ![]() Для управления ячейками MEMS Sharp использовала технологию IGZO, оксидные полупроводники которой имеют более подвижные носители, чем у аморфного кремния, обычно используемого для управления в ЖК панелях. Когда отображается изображение с меньшим количеством уровней градации или черно-белое, MEMS ячейки открываются и закрываются реже, улучшая эффективность использования подсветки и дальнейшее снижение энергопотребления. На выставке Sharp показала три 7-дюймовых MEMS дисплея, с разрешением 800 х 1280 и плотностью около 220 ppi. Sharp разработала эти три дисплея в сотрудничестве с американской Qualcomm, которая заинтересована в промышленном выпуске подобных дисплеев и выступила спонсором разработки промышленного процесса на основе передовых технологий Sharp.
