Инновационные телевизоры с технологией QD-OLED: перспективы развития

На выставке CES 2022 в центре внимания оказался телевизор Bravia XR A95K от компании Sony. В нем применена передовая гибридная технология с квантовыми органическими светодиодами. QD-OLED обеспечивает более яркое и контрастное изображение, чем существующие на рынке устройства. За качество картинки отвечает также мощный процессор Cognitive Process XR с возможностью анализа данных о восприятии пользователем изображения и автоматического увеличения яркости цветов в светлых участках и насыщенности черного – в темных. Разберемся, в чем преимущество представленного телевизора и будут ли другие производители использовать новую технологию.

Типы матриц в дисплеях

В мониторах применяются разные способы создания изображений. Современные линейки бытовой техники оснащены такими видами дисплеев:

  1. LED: применяется панель LCD и светодиодная подсветка. Между двумя параллельно расположенными поляризованными слоями находится прослойка из жидкокристаллических кристаллов с интегрированными в нее пикселями RGB. Стеклянная панель с прозрачными электродами регулирует интенсивность света. К недостаткам такой техники относят низкую контрастность и недостаточную цветопередачу.
  2. OLED: используются органические светодиоды, которые не требуют дополнительного источника освещения. Каждый пиксель испускает свет. Белая, черная или цветные ячейки не влияют друг на друга. Свет от ярко освещенной точки не проникает к рядом расположенной частице. Благодаря этому картинка стала максимально контрастной и четкой. Черный цвет стал насыщенным и глубоким. Увеличился угол просмотра. Внедрить эту матрицу во все телевизоры не позволяет высокая стоимость.

 

  1. QLED: применяются светодиоды на квантовых точках. Каждый пиксель также излучает свет, но не самостоятельно, а от дополнительного источника, как в ЖК-панелях. По яркости и реалистичности цветопередачи превосходят OLED-мониторы, но уступают им в четкости.

Особенности мониторов с новой технологией

Многие производители в премиальные модели устанавливают OLED-экраны. Компания Samsung же считает перспективной развитие технологии на основе квантовых точек и работает над ее модернизацией. Целью инновационной QD-OLED – достичь свечения и окрашивания в разные цвета нанокристаллов при прохождении через них электрического тока.

Разработаны новые дисплеи, в которых совмещены OLED-панели и квантовые точки, представляющие собой нанометровые полупроводниковые частицы. В этом суть перспективной гибридной технологии. Она совмещает достоинства OLED и QLED-дисплеев. В экранах используют синие органические светодиоды. Каждый пиксель светится самостоятельно.

 

Преимущества и перспективы техники с QD-OLED-экранами

Приверженцы домашних кинотеатров, по заверениям производителя, должны оценить реалистичность и красочность видео на новых дисплеях. К достоинствам экранов QD-OLED относятся:

  • высокая яркость;
  • широкий угол обзора;
  • небывалая контрастность;
  • отличный уровень черного цвета;
  • живая и реалистичная картинка.

Компания Samsung заявляет, что на ее панелях изображение будет более детализированным. Чтобы понять, так ли это, нужно оценить технику в работе. Дата выпуска новинок неизвестна. Так что пока можно наслаждаться просмотром видео на отличных контрастных и четких экранах с испытанной технологией OLED.
