LEDs, LCDs, OLEDs and 8Ks
How do Foxconn liquid crystal displays compare to newest technology?

WAUKESHA — Foxconn Technology Group has announced it will make liquid crystal displays — LCD — at the proposed southern Wisconsin plant that could come online as soon as 2020. Foxconn officials say the display plant will expand their production of super high-definition 8K LCD screens backlit by LEDs, which sounds extremely advanced technologically. But other technologies are gaining momentum that could offer an even thinner, crisper and more energy-efficient display in the future.

Here’s a side-by-side comparison of LED and OLED and a basic rundown of Foxconn’s display products:
¦ Most LCD screens, monitors and televisions on the market are backlit with a light panel made up of clusters of LED lights.
¦ LED (light-emitting diode) screens cannot go fully black and have longstanding problems producing a dark black that allows for higher contrast and a more realistic image on screen.
¦ LEDs are widely manufactured and therefore have a much lower price point than OLED televisions and screens.
¦ Though LEDs are cheaper for consumers, they do draw more power and are less energy-efficient than OLED screens because the LED light clusters don’t have the capability to go completely black.
¦ Also known as organic light-emitting diode, OLED screens are made of organic compounds that illuminate with electricity.
¦ Instead of using a thicker LED light panel, OLEDs can be made incredibly small and thin; so small that they can be used as individual pixels that are illuminated by their own, separate light.
¦ OLED pixels have the ability to light up and go completely black or shut off. Therefore the OLED displays produce a deep black, which greatly adds to overall picture quality.
¦ OLED displays are more energy-efficient because of their ability to have individual pixels essentially turn off when they go black. However, when watching bright video like a football game or Olympic games, more power will be used.
¦ Due to picture quality and energy efficiencies, many tech writers have scored OLED screens and televisions as the superior technology, only detracted by things like cost and size of LEDs.

¦ 8K resolution has four times more pixels than 4K resolution, which is currently widely available in the U.S.
¦ Compared to other screens with a height of 1,080 pixels or 3,840 pixels in 4K screens, 8K has a whopping 7,680 pixels — creating the clearest image imaginable.
¦ 8K televisions are expected to be widely sold in the U.S. between 2018 and 2020.
¦ The clear images produced on 8K screens are already starting to aid the aviation, medical and automotive industries worldwide.
¦ 8K video storage and editing requires higher computing power. Foxconn expects to use ultra-fast 5G wireless internet to accommodate the higher resolution images.
Facts at a glance:
¦ Foxconn will build 8K LCD displays backlit by LED lights
¦ Some say 8K technology will be widely available in one to three years
¦ 8K displays are currently only built and available in Japan
¦ 8K video storage and editing requires massive computers and computing power, which consume additional power and bandwidth.
