large display

A large screen is an electronic display with a relatively large or very large screen diagonal. In the 1990s, screens with a diagonal of 19" were among the large screens.

Today, large displays for highest resolution video are manufactured in the 4K and 8K standards with diagonals of over 85". This corresponds to a metric size of 2.14 m. At 8K resolution, 7,680 x 4,320 pixels are displayed, and the resolution and color representation comply with the ITU-T recommendation BT.2020 for Ultra-HDTV (UHDTV). The HDR technology used, High Dynamic Range (HDR10), has a dynamic range of 10 bits and can display 1,024 brightness levels.

Large screens can be multi-touchscreens on which several people work at the same time. Depending on the application, they can be equipped with different user interfaces, such as a graphical user interface (GUI), a voice-controlled or gesture-controlled user interface (NUI). Display technologies can be OLED displays or QLED displays.

If the TVs have large screens, they are usually equipped with a triple tuner for the reception of DVB-C, DVB-S and DVB-T or DVB-T2. They also have an Internet connection via which they can receive Internet television (IPTV) and live streaming. In addition to the above-mentioned signal sources, there are USB interfaces for flash players, Blu-Ray players and DVD drives as well as HDMI interfaces or wireless HDMI for laptops, game consoles or modern players and the DVI interface.
