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:

LED/LCD

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.
 

OLED

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

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.
