Или OLED LCD?
The vast majority of TVs on the market – models with LCD display, which is illuminated by LEDs. These devices are commonly called LED-s, though this LCD – TVs with LED backlight.
In addition to the LCD, on the market are becoming more popular OLED – TVs, but their range is limited, так как это молодая, but promising technology. To date, OLED-panels manufactured by LG and Samsung, TVs that you can buy y.ua on site.
Despite the very limited choice of OLED-TVs have a number of unique advantages. Their main advantage is a very deep blacks and, essentially, infinite contrast, that surpasses even the best plasma TVs – до недавнего времени не рассматривался в качестве стандарта с точки зрения качества черного цвета. Технологическая особенность ЖК-подсветки неравномерна, that is, there are more or less lit areas of the screen, they are especially visible in the dark. В OLED-телевизоров такая функция не применяется. Хоть и некоторые ЖК-телевизоры с передовыми светодиодами заглушками могут похвастаться очень высоким контрастом, Yet most LCD models are black and the contrast is much lower, than the OLED-TV.
TV Ultra HD or Full HD?
In the most popular and purchased resolution televisions is 1920 x 1080 pixels, call them FullHD. They are excellent for watching videos, pictures, playback of graphics console or PC? The recommended minimum resolution is only 1920 × 1080.
ultra HD, better known as 4K TVs, have a screen resolution twice as high as compared to Full HD. Respectively, Ultra HD TV can display the image 3840 pixels, a TV with Full HD – 1920, which is two times less. The situation is identical in height, так и по горизонтали. Удвоение разрешения вертикальной и горизонтальной дает очевидные преимущества в виде более резкого и четкого изображения, Ultra HD TV can display 4 screen size with Full HD, the image has a 4-fold more pixels D. See well-made pictures on the big screen with a resolution of UHD can be truly unique experience.
Another advantage of 4K / UHD comes to 3D technology, that is, three-dimensional images. Currently on the market of 3D-TV we have two technology: active (instantaneous) and passive (polarization). To greatly simplify the system provides active (in theory) complete resolution of Full HD, but its main disadvantage is flickering (in practice there are TVs with active 3D with the 3D image resolution below, чем Full HD). In turn, passive system technology provides stable and flickering 3D-image, at the expense of vertical resolution being halved (1920×540 pixels). Luckily, TV 4K / UHD, using a passive method for creating three-dimensional images are able to display a complete Full HD in 3D-mode, by doubling the vertical screen resolution.
