As soon as the backlight is switched off, the reflective black-and-white part uses the ambient light e.g. from a lamp or the sun which enters the display and is reflected by a mirror behind a large part of each pixel. On its way back the brightness of each subpixel is controlled by the liquid crystal similar to the colour mode. In order to reduce loss of brightness, the colour filters are dropped in this area. Therefore each subpixel becomes visible to the user as a black-and-white pixel with 64 grey-scales and the horizontal resolution is tripled.

To get the most out of your 4K TV, you need 4K content. Fortunately, there's 4K content everywhere. Most of the major streaming services, like Netflix, Amazon, iTunes and Vudu all have 4K available. There are also Ultra HD Blu-ray players and gaming consoles , like the PS5 and Xbox Series X. If you have a PC, many video cards from the last few years can render games at 4K, with varying degrees of success.

This shows the relative number of pixels in each of the major resolution formats. Not actual size of course; this is a chart not a visual representation (though it is to scale if you click on it).

Pixel Qi Corporation, the world’s only non-captive LCD screen designer, has pioneered a new class of screens combining an e-paper look with color and video. These screens offer dramatically lower power consumption, full sunlight readability, and stunning text rendering for reading. The screens use standard LCD manufacturing equipment and materials with a full suite of new inventions to give users real benefits they can see. Pixel Qi, with offices in Silicon Valley, California and Taipei, Taiwan, is a spin-off of One Laptop per Child (OLPC) and was founded by OLPC‘s former CTO Mary Lou Jepsen. Pixel Qi believes that the future of computing is all about the screen and is dedicated to continuously delivering innovative screen technologies rapidly into high volume mass production. Why Pixel QI Displays?

This is another source of confusion, since decades of TV discussions have talked about vertical resolutions, and then all of a sudden we're talking about "4K TVs," which refers to the horizontal resolution. Don't blame me, it wasn't my idea.

Resolution, in terms of TV hardware, refers to the number of pixels that compose the picture on the TV. A single pixel, or discrete picture element, consists of a tiny dot on the screen.

There are numerous resolutions found on flat-panel TVs. Older TVs, and many 32-inch models sold today, have a million or so pixels (720p). More recent and slightly larger TVs (typically 49 inches and smaller) have a little over 2 million pixels (1080p). Even newer and bigger TVs (typically 50 inches and above, although numerous smaller sizes too) have 8 million (for 4K Ultra HD). And the newest, largest and most ridiculously expensive TVs have over 33 million pixels (8K). You'll have to look very closely, or whip out a magnifying glass, to discern each one.

In the computer world they use an incomprehensible and shockingly un-user-friendly jumble of letters to describe resolution. Well, not "shockingly" since these are computers.

Look, I'm a computer guy, building my own PCs since the early '90s, and even I can't tell you what half these letters mean. I can understand that initially they were implemented to make things easier, but we've got so many resolutions and combinations that now they're just annoying.

In the future, resolution might become irrelevant. Technologies like MicroLED separate size and resolution, so your future 50-inch bedroom TV will have a radically different resolution than the 100-inch living room TV, as opposed to now where they'd both be 4K with different size pixels. Thanks to advancements in video processing, though, this won't matter. They'll all look sharp and detailed.

3Qi is a combination of a standard transmissive colour LCD and a very low power, high-resolution black-and-white display with 64 grey scales.

Here's where I remind you that more pixels doesn't necessarily mean a better picture. There are other aspects of picture quality, such as contrast and color, that are far more important than resolution.

The transmissive colour part of a 3Qi display is designed as known from an ordinary colour LCD.  individual pixel is divided into three cells, or subpixels with red, green and blue colour filter. A backlight  either CCFL or LED placed behind shines through the layer of liquid crystal and the colour filters whereas the orientation of the crystals controls the brightness of each colour.

4K, 8K, 1080p, HD and UHD. If you're shopping for a new TV, you've likely noticed these letter-number combos listed beside the word "resolution." But what's the difference between these resolution types? Is it worth paying more for an 8K TV versus a 4K TV? Does resolution even matter that much? Resolution may not be the most important factor when buying a new TV, but it's still something you should consider. Although it can get confusing, knowing what all the numbers really mean can help you feel more confident in your choice of TV.

Which is why 1080p is not "1K." If anything, as mentioned above, it's "2K" by the same logic that UHD TVs are 4K. That said, most people don't call 1080p 2K; they call it 1080p or Full HD.

Basically, for simple office monitors you'll mainly see FHD (1,920x1,080) and WUXGA (1,920x1,200), but you might also see a resolution of FHD Plus, which is typically 2,220x1,080 pixels. But as you go up in price and size, you'll find more variations in resolution. It's best not to get too hung up in the marketing terms and just focus on the numbers and if the resolution is high enough to meet your needs. For more details, you can dive into and print yourself a cheat sheet from this.

From largest to smallest: 8K (tangerine), 4K Cinema in 1.78:1 aspect ratio (black); Ultra HD (white); 2K Cinema in 1.78:1 aspect ratio (green); Full HD 1080p (red); 720p (blue).

When it comes to TVs, 4K and Ultra HD (or UHD) are referring to the same resolution. Those TVs, along with Ultra HD Blu-ray, and nearly all UHD streaming content from Netflix, Amazon and others, is 3,840x2,160 resolution.

Remember how we talked about digital cinema resolutions only specifying the horizontal resolution? Well TVs, on the other hand, have historically used the vertical to describe resolution (going back to the glass tube days). So 1080p is the vertical resolution. Nearly all HDTVs have an aspect ratio of 1.78:1 (16:9, aka widescreen), so that means a horizontal resolution of 1,920 pixels (1,920x1,080).

When you boil it all down, here's the takeaway: Older and smaller TVs are HD, 1080p. Nearly all new TVs are 4K Ultra HD, which have four times as many pixels as 1080p. Someday you might have an 8K or even 10K TV, but that's a l-o-o-o-o-ng way away.

By the way, 1080i is the same resolution as 1080p, but no modern TV is 1080i. However, most HDTV broadcasts, including those from CBS and NBC, are still 1080i.

Resolution is one of the most common specifications used to sell TVs, partly because "4K" and "8K" sound really high-tech and impressive. However, resolution is not the most important ingredient in picture quality. Just because a TV has higher resolution than another, doesn't always mean it looks better. It might, but not always, and for reasons that have little to do with resolution. A TV with better high dynamic range (HDR) performance, a better overall contrast ratio or better color will look better than one that just has more pixels.

We're starting to see the rollout of ATSC 3.0, now known as NextGen TV. With a NextGen TV tuner, or a TV with one built in, you'll theoretically be able to watch free 4K TV over the air. Just like the initial roll-out of HDTV at the turn of the century, it's going to be a while before 4K programming is common over the air.

One potential source of confusion is that 4K means something different whether you're talking about a TV in your home, or a projector in a theater. Technically, "4K" means a horizontal resolution of 4,096 pixels. This is the resolution set forth by the Digital Cinema Initiatives. Because movies vary in aspect ratio, which refers to the exact shape of the rectangle of screen, no vertical resolution is specified.

That said, it's still worth understanding the various resolutions used by TV makers and others. Here's a bit more, ahem, detail.

8K follows the same logic. If you're talking about TVs, it's twice the horizontal and vertical resolution of 4K TVs: 7,680x4,320. This isn't a cinema resolution yet, at least not outside of the experimental stage. There are a handful of 8K TVs on the market, but it's going to be many years before this resolution is common.

Roughly half the number of pixels of 1080p. It's rare to find a new TV that's 720p anymore. However, all ABC, Fox, ESPN, and their affiliated/sister channels broadcast at 720p. This goes back to the initial HD transition at the turn of the century. (And if you're wondering why your TV doesn't say "720p" on those channels, check this out.) It's also why this resolution is referred to as HD, while 1080p is Full HD or FHD for short.

So Ultra HD TVs aren't technically "4K" by the specifications of DCI, but common parlance has usurped the term so "4K" TVs are 4K TVs even though their resolution is 3,840x2,160. Most companies just say both: Ultra HD 4K.

Before "4K" became common, you'd almost never see "2K." It was pretty much just a cinema resolution, which is why you'll sometimes see 2K used to refer to a "master format." Most digital cinema projectors used in theaters are 2K resolution (some are less). It's 2,048 pixels wide, and again, no vertical resolution is specified by the DCI.
