rollable display screens pricelist

Foldable and flexible displays have been making the rounds in recent years. Numerous phones, monitors, and other devices have been making headlines for incorporating this new and innovative spin on electronic displays.

Manufacturers are also pouring tons of money into research and development, with an apparent belief that they’ll be the next big advancement in display technology. But are they?

Flexible screens are an exciting take on the traditional flat-screen display. And in a sense, they seem like the logical next step in display technology. But this seemingly newfound concept is actually a lot older than you might think. Enter: Xerox PARC.

Xerox PARC, the company that pioneered many of today’s technologies, such as the laser printer and Ethernet standard, also developed the concept of a flexible electronic display way back in 1974. The concept was developed into an “electronic paper” called Gyricon.

Since then, there have been many big changes in the development of display technology behind the scenes. But possibly the biggest one that makes modern flexible screens possible is OLED technology.

Due to the nature of OLED screens, which don’t need separate backlighting to function, it’s now possible to create displays thin enough to bend and flex. Combined with advancements in screen and glass technologies, you have the modern form of bendable and flexible screens and displays.

Modern problems require modern solutions. And while flexible displays are anything but new, novel twists using the technology can showcase how it can be viable going forward and why we could be on the cusp of the next big thing.

Samsung is a manufacturer pushing boundaries with their flexible and foldable phones, but they are not focused solely on the mobile market. Samsung’s Odyssey Ark is a 55-inch curved display able to rotate, pivot, and tilt with Samsung’s proprietary Height Adjustable Stand (HAS). Combined with the curved, densely packed mini LED arrangement, the Odyssey Ark provides unique viewing that fills viewers’ peripheral vision to create a more immersive experience. The Odyssey Ark also gives users full customization by vertically or horizontally orienting the display. One of the Odyssey Ark’s features, Flex Move, allows users to adjust the screen size and ratios to tailor their viewing experience further.

If you’ve watched videos or played games on a mobile device, you know that having a bigger screen can be much easier on the eyes. And this is one space where flexible and foldable displays are looking to revolutionize the tech industry.

Folding phones can also allow us to have larger screens without making them unwieldy. The Galaxy Z Fold 4 boasts an impressive 7.6-inch display but folds down to a mere 6.2-inch phone-sized device that packs a tablet-sized wallop. And as companies continue to work out the kinks in foldable and flip phone designs, we could see phones that fold multiple times to allow for even bigger screens.

But folding and flipping phones aren’t the only ways to shrink our ever-growing desire for larger portable screens. The rollable phone is perhaps the most innovative and smoothest iteration of the big-phone-in-a-small-package.

We don’t have any rollable phones rolling into the market quite yet. But it’s certainly tech that’s in the works. Samsung has filed multiple patents for rollable and scrollable phone designs, while other companies such as Oppo, TCL, and LG have showcased prototypes of this phone style.

It’s uncertain if and when we’ll actually see rollable phones hit the market, but there’s clearly an interest in the tech from major manufacturers looking to push the envelope.

Smartphones seem to be leading the revolution of flexible screens, with folding phones first making their debut in 2018. But laptops would soon join the fold with the release of the Lenovo ThinkPad X1 Fold in 2020.

Being the first laptop with a foldable screen, it – and its successor, the Lenovo 16.3-inch ThinkPad X1 Fold – is here to prove that folding screens aren’t solely limited to smartphones.

Curved monitors are nothing new in the PC space and have made it to the mainstream. With the push for larger displays, having a curved screen allows for better immersion and utilization of the extra screen real estate. And so, unsurprisingly, flexible display technology is also making its way into the home as well.

This makes it ideal if you want a multipurpose monitor where you can choose between a flat or curved panel based on what you’re doing. For productivity-oriented tasks, a flat display might suit you more, while when gaming, having a curved display can create a more immersive environment.

However, while it’s a first in the PC display space, large flexible screens aren’t entirely new. In fact, they date back to at least 2014, when Samsung and LG unveiled a couple of massive flexible TVs during that year’s CES.

Curved and flexible TVs have been a much harder sell than their smaller computer monitor brethren, likely because they don’t work so well in the living room context. But what about rollable TVs?

Much like rollable smartphones, rollable TVs are probably the most interesting use of flexible display tech so far, allowing you to have a monstrous screen that can completely hide away with a simple push of a button.

Yet, unlike the rollable smartphones that companies have showcased in the past, where they’ve been little more than a tech demo of what’s to possibly come, rollable TVs are a product you can actually buy. Or, at least, there’s one.

The 64.5-inch LG OLED R debuted in 2021 and is the world’s first commercially available rollable TV. Of course, it’s not something you or anyone is likely to actually purchase, thanks to its eye-watering $100,000 price tag. Nevertheless, it’s an intriguing take on where flexible screens can possibly lead us to in the future of televisions.

Flexible screens present a number of advantages to their rigid counterparts that could reshape how we think of smartphones, computers, and televisions in the future. But right now, we’re in the awkward early stages where there are still plenty of kinks to work out.

Nevertheless, flexible display devices costing thousands make it a hard sell for most consumers. Comparable, non-flexible alternatives are available for much less, making them even less compelling.

Durability is another important factor for adoption. Display tech over the last 20 years has been rather frail, and consumers are keenly aware of this. Plastic and ultra-thin glass screens are highly susceptible to damage, and the addition of mechanical action – another potential point of failure – to primarily electronic devices makes for a justifiable concern, further hampering adoption.

DSCC has released its latest OLED market forecast, and the company forecasts a 8% CAGR revenue growth, with the market reaching $64 billion in revenue in 2026. The growth will be fueled by high demand for laptop, monitor and tablet displays. The smartphone and OLED TV market will also continue to grow.

DSCC sees a 31% CAGR shipment growth for laptop displays, to reach around $2.4 billion in 2026, and a 95% CAGR unit growth for monitor OLED displays, which will reach $1.3 billion in 2026 (up from $200 million in 2022). This is fast growth for monitor OLED displays, but slower than DSCC previously estimated, due to competition for miniLEDs, rigid OLED capacity that will be used for laptops and tablets and lower demand to mirroring display monitors.

flexible display price (Liquid crystal display) are made of liquid crystals that form digital images made visible through ambient light or through LED backlight. LCDs are used in the place of other displays that are less efficient such as cathode ray tubes (CRTs) and have become the most popular display type on the market.

LG’s futuristic rollable OLED 4K TV is coming to the US for an eye-popping price of $100,000. First introduced as a stunning prototype at CES 2018 (and then turned into a real product the next year), the 65-inch set can roll itself up and then back down to fully disappear into its housing unit. That cabinet also contains a front-firing, 100-watt Dolby Atmos sound system.

The OLED R has a middle mode between being fully unfurled and rolled down. LG calls this Line View, and you can use it to display a clock, photos, music controls, and so on.

From a picture quality perspective, the OLED R has technically already been surpassed by newer LG models; the more traditional G1 series introduced earlier this year can get brighter than any of the company’s prior OLEDs, including the rollable. But the OLED R’s panel still checks all of the boxes you’d want from a modern TV: it’s got Dolby Vision, 120Hz 4K gaming, variable refresh rate, auto low latency mode, and more. And as I’d damn well hope for $100,000, all four of its HDMI ports are HDMI 2.1.

During Intel’s Innovation 2022 event, Samsung had an exciting announcement — a 17-inch rollable screen, the first ever of its type. Moving from folding phones, foldable laptops have been a trend in 2022 with machines like the Asus Zenbook 17 Fold, but Samsung is going with a different design. Instead of folding, you’ll roll the screen out to expand it.

Samsung showed a quick demo on stage with Intel’s CEO Pat Gelsinger. The screen is the same size as 17-inch foldable laptops like the Lenovo X1 Fold Gen 2, but you simply push on one side to roll the screen back into the body. Samsung didn’t announce when the display will show up, or in what machines, but it will likely be soon.

Foldable display tech is being applied in other areas, as well. For example, Corsair recently showed off the Xeneon Flex. It’s a 45-inch 21:9 ultrawide monitor fit with an OLED panel, but that’s not what’s interesting about it. You can grab the sides and bend the monitor in for a more aggressive curve while you game. This form factor is sure to show up in other displays going into the next year.

Although Intel’s announcements at Innovation 2022 were mostly expected — like the launch of its 13th-gen Raptor Lake processors — Samsung’s rollable screen was a welcome surprise. Intel also had a surprise with the release date of its Arc Alchemist GPUs, stating that gamers “should be frustrated” about high GPU prices right now.

We don’t know when Samsung’s rollable screen will arrive, but hopefully, it will be soon. Intel showed off a demo with the panel using the new Intel Unison tech, suggesting that the display shown on stage is functional and could show up in devices soon.

We"ve seen rollable device concepts from companies like Oppo and TCL, and LG was even working on a commercial rollable smartphone until it quit making mobile devices last year. Now, Lenovo is showing off a laptop with a rollout display, while its mobile division Motorola has a roll-out smartphone — and they look like some of the more practical efforts yet.

Lenovo also showed off a rollable laptop that starts with a typical landscape display and then rolls up to a square shape, making it better for documents or vertical TikTok style videos. Lenovo VP of design Brian Leonard explained in the video that it"s part of Lenovo"s research into novel form factors that started with the ThinkPad 360P laptop/tablet. "It can expand into a much larger screen real estate as the content dynamically adjusts to the screen, offering people an unprecedented way of hyper-tasking for productivity, browsing, and more," he explained.

Motorola already makes a folding device, the Razr, that"s unfortunately only available in China, but rollable devices are even more complex. People seem to love them, though — for instance, LG"s rollable OLED TVwas a popular item at CES 2019. And in some ways, a rolling screen is more elegant than a folding one, as there"s no hinge or crease to worry about. While it remains squarely in the concept realm for now, we"d love to see Lenovo take a shot at commercializing it.

The LG Rollable has been shown off for the very first time! https://t.co/9efT3nK49Bpic.twitter.com/BzlyOFQAHq— PhoneArena (@PhoneArena) January 11, 2021

Although we"ve never had official information on how much the LG Rollable might cost, we"ve come to expect high prices of smartphones that introduce new technology to the market. Those, such as the Galaxy Z Fold 2, Motorola Razr 2020 and Microsoft Surface Duo range anywhere between $1,400 and $2,000. The LG Rollable/Slide could have easily cost between $1,400 and $2,000.

We don"t have official images of the phone, but we do have concept renders (shown above, courtesy of LetsGoDigital), in addition to recent LG Rollable patent images (shown below).

The LG Rollable phone will feature a flexible OLED display, which as the phone"s name suggests, will be able to roll inside the housing of the phone when the user needs a normal-sized, pocketable phone experience. When the user needs it to become a tablet, the LG Rollable"s display will automatically roll out (via a motorized mechanism), turning the smartphone into about a 7.4-inch tablet.

Thanks to the fact that this is a sliding-display phone and not a foldable, there will be no crease in the middle of its screen, like we"ve come to expect from folding phones. The LG Rollable phone"s display does not just have one single bending point.

In addition, below is possibly an alternative LG Rollable design, sporting a smaller outer display. This image comes from yet another LG patent that surfaced on February 12th.

On April 6th, 2021, the following Tweet appeared to show what the LG Rollable would"ve looked like, suggesting that the phone was in either fully or nearly completed state.

The phone will run Android 10 or possibly 11, with its interface smoothly adapting to the display"s rolled-out and rolled-in states and adjusting to how the user holds the phone in terms of orientation. When the display is rolled into the body of the phone, the LG Rollable will function just as a normal-sized Android smartphone. And when the display is rolled out, the phone is likely going to allow for a seamless multi-tasking experience with multiple open apps, if the user needs it. If not, the phone will simply display a single app or video or game on a larger scale.

Here is a demonstration of how the Android operating system will adapt to rollable smartphones like the LG Rollable, in both their "standard" and rolled out display modes:

As suggested by its most recent patent, the LG Rollable may not have physical volume buttons, but will rely on software touch controls. The more recent patent of an LG rollable phone also shows a vertical camera module holding three cameras, at least one of which will likely be wide-angle.

Folding screens have become a common sight in recent years, thanks in large part to Samsung’s two lines of foldable phones, the Z Flip and Z Fold. As other manufacturers join in, foldable device prices are quickly going down, promising a new age of personal computing. But how do folding screens actually work?

Whether you’ve always been curious about how folding screens work or have yet to consider it, we’ll give you a crash course in foldable displays and the cool tech that makes them possible.

Simply put, millions of specks of color combine to form the images we see on screen. There are different ways to achieve this, resulting in the various displays you see out there, including LCD, OLED, and, more recently, micro-LED and mini-LED.

Then over the last decade, display manufacturers produced display substrates made of flexible plastic that can bend without breaking. Plastic-based displays made possible the creation of the first phones with curved displays, like the Galaxy Note Edge of 2014.

As technology advanced, display makers figured out ways to increase the amount of flex they could safely build into a screen. Crucially, they also solved the problem of durability, allowing screens to bend thousands of times without breaking. Eventually, this path led us to today’s folding screens, which can fold almost like a sheet of paper.

Manufacturers have been teasing folding screens for over a decade, but the first folding phones only came out in 2019. There’s a reason folding screens needed so much time to mature — or more accurately, there are many reasons for this.

The flexible substrate is only part of the equation. Scientists and engineers had to solve ridiculously hard problems like manufacturing substrates that are light and flexible but can withstand years of mechanical stress; ensuring that all the bending and folding doesn’t affect image quality over time; creating an equally flexible protective layer for the screen; and making sure that all the other tech that goes into the display still works. When all this was done, other smart people had to devise ways to incorporate the flexible displays into folding phones while maintaining the insanely high standards we expect from our electronics. A very tough job indeed.

Before we look at the individual components of a foldable screen, it’s important to note that all folding screens you see on the market today are of the OLED variety. OLED screens do not have a backlight like LCDs — instead, the pixels themselves emit light when power is applied to them. Because of this, OLEDs can be made about 30% thinner and lighter than LCDs. Coupled with other benefits over LCD, OLED is the first choice for flexible screens, but flexible LCD displays do exist.

To understand how foldable OLED displays function, it’s helpful to visualize the display as a very thin (and probably not very tasty) layer cake. Each layer of this high-tech cake has a specific role. These layers are laminated together in a very thin package that’s fractions of a millimeter thick. Let’s go through them.

Substrate layer — Also called the board, this is the very base of the screen, which supports all the other layers. On a flexible display, the substrate is made of plastic or, less commonly, metal. Most flexible screen devices today use a substrate made of a polymer plastic called polyimide (PI). In addition to being flexible and insulating, polyimide features high mechanical strength and thermal stability.

TFT layer — Applied on top of the flexible substrate, the TFT (thin-film transistor) layer controls power delivery to each pixel. Think of it as a “power grid” that connects all the pixels in the display. On an OLED screen, unlike on LCD, each pixel can be controlled individually, allowing for high contrast rates and lower power consumption.

OLED layer — The light-emitting layer is made up of individual pixels, each of which comprises red, green, and blue subpixels. Each pixel can hit a certain color and luminosity by varying the amount of power its subpixels receive. In turn, pixels combine to form the image we see on the display. The OLED layer is made of several sub-layers, including a cathode, an anode, and a layer of organic light-emitting material sandwiched between them.

Cover layer — Also called the encapsulation layer, this is the layer that seals and protects the other layers. It’s also the layer users touch when they interact with folding screens. In terms of materials, the cheaper option is polyimide (same as the substrate), while more recently, we’ve seen manufacturers adopt ultra-thin glass (UTG). UTG is tougher than plastic and feels more like regular glass, while still being able to bend. UTG is what Samsung has been using on the latest Z Flip and Z Fold.

Folding screens can be of the in-folding or out-folding variety. On an in-folding display like the Galaxy Z Flip series, the display is hidden inside the device when folded, which helps with durability, but it does tend to create a slight crease on the screen. On an out-folding display (like the HUAWEI Mate XS 2), the display bends around the outside of the device when folded. That leaves it exposed to scratches, but it provides a crease-free aspect.

Not all flexible display devices fold. We’ve seen devices with rollable displays that roll up and disappear inside the device’s body. Examples include the OPPO X rollable phone or LG’s crazy OLED R rollable TV.

The display is a key aspect of how folding screens work, but it’s not the only one. The hinge may be just as important to the user experience. Manufacturers have poured a lot of resources into ensuring that hinges in their foldable products work smoothly and consistently, have the right amount of “snap,” and provide a smooth surface for the display to sit on.

Another key factor is durability. By definition, foldable screens feature moving parts, which opens up the possibility of water, dust, and other contaminants entering the device. Indeed, we’ve seen issues with debris getting lodged below the screen on some devices, which ruins the user experience and can damage the screen.

Numerous manufacturers have already released or at least teased foldable screen products, including phones, laptops, and even TVs. It’s easy to envision a future where tablets, wearables, gaming consoles, and even home appliances feature screens that bend. Innovation will also come from stretchable, wearable, and even skin-embeddable displays. In the meantime, as more resources are invested in the technology, folding screens will only get better.

It’s been a slow rollout for smartphones that transform into larger-screened tablets using a flexible OLED display, but LG is hoping it can help accelerate the adoption of these adaptable devices, and maybe knock a few bucks off its own steep price tags, with a

Given how delicate the current crop of OLED displays can be, Samsung’s approach seems to be better suited for consumer devices, as there’s less risk of a protected folding screen getting damaged when closed and banging around inside a user’s pocket. The drawback to that approach is that, in order to make devices like the Galaxy Fold 3 useable as a smartphone when folded, a second screen has to be added to the outside. This, undoubtedly, contributes to high prices, as the Fold 3 costs $1,800.

Any flexible OLED screen can be folded in both directions—it’s a neat tech demo we’ve seen since the technology was first introduced decades ago—but the displays, their added protective layers, and even the mechanical hinges on devices, are all optimized to increase durability for folding motions in one specific direction only. It doesn’t have to be that way, though, as LG has demonstrated at the 2022 Society for Information Display (SID) show currently taking place in San Jose, California. There, the

Despite the added flexibility, LG claims the new OLED panel (which boasts a resolution of 2,480 x 2,200 pixels, or 413 pixels per inch) can still be folded over 200,000 times without severely damaging the screen or “compromising its performance,” which is the same durability claims Samsung makes for the Galaxy Fold 3. But unlike the Galaxy Fold 3, a device using LG’s new panel could go from a larger tablet to a more compact smartphone form without the need for an additional screen when folded outward, while still allowing a user to then completely fold it the other way around to ensure the display is protected when slipped into a pocket or a bag. Unfortunately, there’s no timeline on when new devices might adopt LG’s new screen tech, but as companies are desperate for gimmicks to help justify the cost of folding smartphones, it’s safe to assume LG won’t have trouble convincing companies to take advantage of it.

Recently, researchers have created a small flexible OLED display entirely made using 3D printed processes. What challenges do flexible OLED displays present, what did the researchers demonstrate, and how could it help reduce prices in the future?

Display technology has come unbelievably far since the invention of the first CRT screen. What used to require hundreds of watts of power and many kilograms of supporting equipment has been shrunk down into displays measuring a few grams with higher resolutions, improved brightness, and increased refresh rates.

Despite the many incredible achievements made in display technologies, consumers continue to demand more from their products, and one area of growing interest is flexible displays. Flexible displays are already integrated into consumer electronics, such as smartphones, and can expand in size of the product. For example, a smartphone with a flexible display can start off at the same size as a typical smartphone but then open up like a book and effectively double the screen size.

But creating flexible displays comes with a range of challenges, and these challenges make them extraordinarily expensive. The first challenge is finding materials with semiconductive properties that can flex, and traditional semiconductors cannot do this as they are crystalline in structure, so organic semiconductors are used. Even then, every display component has to be flexible, including contacts, wires, and the substrate.

The second challenge is developing manufacturing processes that can create flexible displays reliably. Unlike traditional parts, which are made up of discrete solid objects that can easily be placed and manipulated, flexible parts can present difficulty as they can be structurally unstable. This means that parts may flex and move around during the manufacturing process. Many organic semiconductors are produced using thin films and chemical deposition stages which are not cheap to do.

The third challenge is longevity and reliability. For a flexible display to be practical, it must withstand many flex cycles without losing performance. This was one of the biggest challenges faced by researchers in the early days of flexible display technologies, as most early displays would fail after being folded a few times. It is clear that researchers have found solutions, but this has come at a substantial monetary cost to the final display.

Recently, researchers from the University of Minnesota have successfully demonstrated a small flexible OLED display produced entirely using a single 3D printer. The new display is built up in layers, and the use of an XY gantry system allows for the placement of material exactly where it is needed.

All parts of the printed display were done at room temperature, including the light-emitting layer, and all layers of the display were done using the same machine. The printed layers include the electrodes, the interconnects, insulation, and encapsulation which produces a completely functional device with no additional steps needed.

The final display has a resolution of 8 x 8 pixels with a total pixel count of 64. While this may be trivial compared to modern displays, it must be appreciated that the entire display was created using a 3D printer with no additional manufacturing steps, all at room temperature. Furthermore, the display was demonstrated to be fully operational, and the display was able to produce a consistent display even after 2,000 bending cycles.

While the ability to create a 3D printed display sounds promising, it must be understood that 3D printers are extremely slow in operation, and trying to get one to print a 1080 display would take an enormous amount of time (assuming that the printing head delivers individual drops). The significance of the development is not so much that it uses a 3D printer as it is that the process was completed in a typical lab at room temperature.

Modern, flexible OLEDs have to be produced in state-of-the-art facilities that often cost hundreds of millions to build (depending on the size and nature of fabricated parts). The use of such facilities increases the final price of flexible OLED displays, and eliminating this would allow displays to be made in standard factories with controlled environments.

But if this technology could be transferred into an inkjet printing system, the ability to create large displays at speed may be possible. If created, an inkjet display fabricator would dramatically help bring the price of flexible OLED displays down while simultaneously demonstrating new uses for inkjet technologies.

Among the various improvements that smartphones and tablets have received over the last decade, flexible displays are undoubtedly one of the most interesting propositions and one with a huge potential to change the market. The technology is still relatively new, despite several companies exploring the tech for more than a decade.

After seeing several new devices successfully integrate flexible displays with varying levels of success, it"s clear that this tech is here to stay. The only question right now is how long it will take for flexible displays to become commonplace. Let"s take a look at how modern flexible displays work and future considerations for this corner of the market.

Smartphone displays are traditionally rigid due to the glass layer used in their production. However, modern OLED-based designs have successfully removed the need for that, instead implementing the screen in a very thin layer, to the point where it becomes flexible. The screen is then covered with a thin plastic layer, which is unfortunately susceptible to scratches.

In some cases, flexible displays are just an illusion. Some devices feature two or more displays lined up next to each other, with special emphasis placed on removing the border between them. These devices are usually more versatile in terms of the kinds of upper layers they support, in some cases including a full glass cover.

Flexible displays have been around for a decade now. Initial designs were rather underwhelming—but some of them ended up being repurposed into other devices. For example, the Galaxy Note Edge"s curved screen actually started as a prototype for a flexible display device.

The Galaxy Z Flip 3 is a notable example of a device that incorporates a flexible display, and some claimed that it should set some new trends on the market. Unfortunately, other manufacturers haven"t tried to follow the trend, so it remains to be seen whether the idea has any true potential. The device sold well enough, which is a good sign.

And in some cases, flexible displays were used to achieve a different effect. The iPhone X, which started the trend of screens with curved corners, actually used a flexible display to accomplish that without sacrificing any real estate around the bezels.

Flexible displays remain relatively expensive compared to their regular counterparts and often sacrifice visual quality. This is especially noticeable when the screen is folded at a particular angle. At the same time, flexible screens tend to have a more limited lifetime compared to traditional ones.

For most user"s needs, current designs should be able to last a very long time. But this is still a point that needs to be addressed by most manufacturers, especially in the context of the higher prices attached to flexible display devices.

It"s also important to note that flexible displays have huge potential outside of the smartphone market. Other devices can utilize them to improve their usability. Furthermore, with wearable gadgets increasing in popularity, new gadgets coming out in the future are likely going to take advantage of this technology.

Smartwatches are a good candidate for flexible display technology. Their designers already go to great lengths to make their displays as compact as possible, and flexible displays offer some direct advantages in this regard. They tend to be thinner than traditional displays, which makes them a good fit for devices of this kind.

Then there are medical devices and other specialized use cases. Even if flexible displays don"t immediately take off, they will find a place in other areas. It will be interesting to see what kinds of changes they facilitate in other markets.

Gaming is also shaping up to be a field where these devices could have a viable place. Between virtual reality and the new features being introduced in modern consoles and their controllers, we might see some approaches that integrate flexible displays.

With all that said, the main question remains—will this eventually become a common trend on the market as a whole? As we mentioned above, there are specialized cases where bendable or flexible displays have potential.

But at the same time, it"s questionable how fast this tech will be adopted in general, depending on price, application, and other availability factors. New developments in the field have made the production process more affordable, but it will probably take a while until foldable displays establish a permanent presence on the market and become commonplace.

Also known by the name roll-up display, a flexible roll-up LED screen is one which is easy to bend, can be rolled-up, scrunched, and is typically manipulated in ways that are not possible through the conventional display. You can roll up the display such as newspaper, making flexible screens simple to move around, or it can be stored in little spaces when these don"t get used.

Viewing on the flexible LED is possible because of the benefits in organic light-emitting diode(OLED) technology, which would be a step ahead of the light-emitting diode (LED)from where light occurs from the back panel. While removing the requirement for the back panel, it is possible to display can bend.

A rollable or a flexible display would mean an electronic type visual flexible display, rather than the conventional flat-screen displays nowadays seen in a lot of electronic devices. In the past years, there has been an uplifting interest from various consumer electronics manufacturers for applying display technology in mobile phones, e-readers, and other types of consumer electronics. These screens are possible to roll like scroll without image text getting distorted. The technologies can involve building rollable displays that include Gycricon, electronic ink, OLED, Organic LCD.

The thing that separates your conventional LCD televisions from video projector screens is that you can"t roll up the TV when you won"t view it. Until now, the roll-up TV, (also known as the rollable TV) arrived. Let"s know what this would mean for the customers.

The underlying technology required for using a roll-up TV is the OLED (Organic Light Emitting Diode). The OLED TVs use an organic structure meant to form pixels to form images, without the requirement for additional backlighting. This also makes the OLED TVs different compared to the QLED TVs or the LCD/LED TVs. The OLED screens can be made so when they"ll bend curve, fold, and also roll while depending on the application (like the displays of the in-car instrument and foldable smartphones).

The thin OLED TV display panel would be combined in little interlocking segments with the folding brace on the screen back for securing it to the rolling motorized mechanisms. The screen panels would wrap around the cylinder within the storage housing. The total roll-down and roll-up time would be around 10 seconds (can be different from the screen sizes).

The screen panels that you see in the roll-up TV were developed and made through the LG Company. (Not the LG Electronics). The LG electronics company is the first brand ideal for adopting the rollable LG OLED technology for consumer TV.

They"re generally available in 65-inch size screens. The rolling screen is available for viewing in three positions: The Line View, Zero View, and Full View.

The OLED technology also doesn"t support any resolution like the 1080p (FHD), the 4K (UHD), and the 8K. However, the LG Display selected the 4K that can be implemented on the first generation rolling OLED TVs. Also, manufacturers add video processing features like HDR and upscaling.

With different manufacturers, you can include more base features for housing screens. The LG-R series base also contains a rollable sound system of the TV (you can think of this as a huge soundbar). The sound system also features a 5.1 channel speaker configuration backed through 100 watts amplification. No firing or height speakers are there but audio processing algorithms make a height effect for the source of Dolby Atmos. Additionally to the sound system, the base also provides many input connections (such as HDMI, etc...) with a tuner.

When craving the best and latest and you"ve got spare cash, then it would be best to have it. However, it would be best to wait for some time to ensure the reliability of the concept. You can wait till the concept grasps some market demand (just like the Curved screens and 3D), prices can be down and there are many more available screen sizes as well.

The foldable display qualities provide adequate compactness when it is not being used. Rollable OLED screens also offer great performance features that are not possible with the current day LCDs. Also for their lighting use, the rolling OLED can provide various benefits over fluorescent and incandescent lighting. OLED benefits also include:

* Light and Thin Weight- The rolling OLEDs are built on thin metal or plastic foil. The rolling OLEDs are thin and light compared to the backlit LCDs along with other displays nowadays available in the market. So the portable computers, cell phones, and other display products can also be small and light. Also, the FOLED technology facilitates easy] wall-mounted televisions along with the installation of the white OLED lighting tiles in settings, and make novel architecture uses not possible with the current day incandescent and fluorescent lights.

* These are safer, more durable, and impact-resistant - Breaking glass is a major issue for display-containing products and is a safety concern in the lighting field. The metal and plastic-based OLEDs can essentially eliminate such issues while also making obvious benefits in both lighting and displays.

Nowadays flexible screens are total HD and provide resolution for more than 1,200 and 810 pixels. The current prototypes are around 18 inches, but the innovators also include the LG expect for pushing flexible screens to 55-inch size. The LG display provided a look at the 180inch prototype screen at Consumer Electronics Show in January 2016. It is possible to manually operate the TV lifts, but these are often motorized to make it convenient.

A flexible display or rollable display is an electronic visual display which is flexible in nature, as opposed to the traditional flat screen displays used in most electronic devices.e-readers, mobile phones and other consumer electronics. Such screens can be rolled up like a scroll without the image or text being distorted.electronic ink, Gyricon, Organic LCD, and OLED.

Electronic paper displays which can be rolled up have been developed by E Ink. At CES 2006, Philips showed a rollable display prototype, with a screen capable of retaining an image for several months without electricity.pixel rollable display based on E Ink’s electrophoretic technology.flexible organic light-emitting diode displays have been demonstrated.electronic paper wristwatch. A rollable display is an important part of the development of the roll-away computer.

With the flat panel display having already been widely used more than 40 years, there have been many desired changes in the display technology, focusing on developing a lighter, thinner product that was easier to carry and store. Through the development of rollable displays in recent years, scientists and engineers agree that flexible flat panel display technology has huge market potential in the future.

Flexible electronic paper (e-paper) based displays were the first flexible displays conceptualized and prototyped. Though this form of flexible displays has a long history and were attempted by many companies, it is only recently that this technology began to see commercial implementations slated for mass production to be used in consumer electronic devices.

The concept of developing a flexible display was first put forth by Xerox PARC (Palo Alto Research Company). In 1974, Nicholas K. Sheridon, a PARC employee, made a major breakthrough in flexible display technology and produced the first flexible e-paper display. Dubbed Gyricon, this new display technology was designed to mimic the properties of paper, but married with the capacity to display dynamic digital images. Sheridon envisioned the advent of paperless offices and sought commercial applications for Gyricon.

In 2005, Arizona State University opened a 250,000 square foot facility dedicated to flexible display research named the ASU Flexible Display Center (FDC). ASU received $43.7 million from the U.S. Army Research Laboratory (ARL) towards the development of this research facility in February 2004.demonstration later that year.Hewlett Packard demonstrated a prototype flexible e-paper from the Flexible Display Center at the university.

Between 2004–2008, ASU developed its first small-scale flexible displays.U.S. Army funds ASU’s development of the flexible display, the center’s focus is on commercial applications.

This company develops and manufactures monochrome plastic flexible displays in various sizes based on its proprietary organic thin film transistor (OTFT) technology. They have also demonstrated their ability to produce colour displays with this technology, however they are currently not capable of manufacturing them on a large scale.Dresden, Germany, which was the first factory of its kind to be built – dedicated to the high volume manufacture of organic electronics.plastic and do not contain glass. They are also lighter and thinner than glass-based displays and low-power. Applications of this flexible display technology include signage,wristwatches and wearable devices

In 2004, a team led by Prof. Roel Vertegaal at Queen"s University"s Human Media Lab in Canada developed PaperWindows,Organic User Interface. Since full-colour, US Letter-sized displays were not available at the time, PaperWindows deployed a form of active projection mapping of computer windows on real paper documents that worked together as one computer through 3D tracking. At a lecture to the Gyricon and Human-Computer Interaction teams at Xerox PARC on 4 May 2007, Prof. Vertegaal publicly introduced the term Organic User Interface (OUI) as a means of describing the implications of non-flat display technologies on user interfaces of the future: paper computers, flexible form factors for computing devices, but also encompassing rigid display objects of any shape, with wrap-around, skin-like displays. The lecture was published a year later as part of a special issue on Organic User InterfacesCommunications of the ACM. In May 2010, the Human Media Lab partnered with ASU"s Flexible Display Center to produce PaperPhone,MorePhone

Research and development into flexible OLED displays largely began in the late 2000s with the main intentions of implementing this technology in mobile devices. However, this technology has recently made an appearance, to a moderate extent, in consumer television displays as well.

Nokia first conceptualized the application of flexible OLED displays in mobile phone with the Nokia Morph concept mobile phone. Released to the press in February 2008, the Morph concept was project Nokia had co-developed with the University of Cambridge.nanotechnology, it pioneered the concept of utilizing a flexible video display in a consumer electronics device.London, alongside Nokia’s new range of Windows Phone 7 devices.

Sony Electronics expressed interest for research and development towards a flexible display video display since 2005.RIKEN (the Institute of Physical and Chemical Research), Sony promised to commercialize this technology in TVs and cellphones sometime around 2010.TFT-driven OLED display.

In January 2013, Samsung exposed its brand new, unnamed product during the company"s keynote address at CES in Las Vegas. Brian Berkeley, the senior vice president of Samsung"s display lab in San Jose, California had announced the development of flexible displays. He said "the technology will let the company"s partners make bendable, rollable, and foldable displays," and he demonstrated how the new phone can be rollable and flexible during his speech.

During Samsung"s CES 2013 keynote presentation, two prototype mobile devices codenamed "Youm" that incorporated the flexible AMOLED display technology were shown to the public.OLED screen giving this phone deeper blacks and a higher overall contrast ratio with better power efficiency than traditional LCD displays.LCD displays. Samsung stated that "Youm" panels will be seen in the market in a short time and production will commence in 2013.

The Flexible Display Center (FDC) at Arizona State University announced a continued effort in forwarding flexible displays in 2012.Army Research Lab scientists, ASU announced that it has successfully manufactured the world"s largest flexible OLED display using thin-film transistor (TFTs) technology.

In January 2019, Chinese manufacturer Xiaomi showed a foldable smartphone prototype.Xiaomi demoed the device in a video on the Weibo social network. The device features a large foldable display that curves 180 degrees inwards on two sides. The tablet turns into a smartphone, with a screen diagonal of 4,5 inch, adjusting the user interface on the fly.

Flexible displays have many advantages over glass: better durability, lighter weight, thinner as plastic, and can be perfectly curved and used in many devices.glass and rollable display is that the display area of a rollable display can be bigger than the device itself; If a flexible device measuring, for example, 5 inches in diagonal and a roll of 7.5mm, it can be stored in a device smaller than the screen itself and close to 15mm in thickness.

Flexible screens can open the doors to novel and alternative authentication schemes by emphasizing the interaction between the user and the touch screen. In “Bend Passwords: Using Gestures to Authenticate on Flexible Devices,” the authors introduce a new method called Bend Passwords where users perform bending gestures and deform the touch screen to unlock the phone. Their work and research points to Bend Passwords possibly becoming a new way to keep smartphones secure alongside the popularization of flexible displays.

Flexible displays using electronic paper technology commonly use Electrophoretic or Electrowetting technologies. However, each type of flexible electronic paper vary in specification due to different implementation techniques by different companies.

The flexible electronic paper display technology co-developed by Arizona State University and HP employs a manufacturing process developed by HP Labs called Self-Aligned Imprint Lithography (SAIL).

The flexible electronic paper display announced by AUO is unique as it is the only solar powered variant. A separate rechargeable battery is also attached when solar charging is unavailable.

Many of the e-paper based flexible displays are based on OLED technology and its variants. Though this technology is relatively new in comparison with e-paper based flexible displays, implementation of OLED flexible displays saw considerable growth in the last few years.

In May 2011, Human Media Lab at Queen"s University in Canada introduced PaperPhone, the first flexible smartphone, in partnership with the Arizona State University Flexible Display Center.

At CES 2013, Samsung showcased the two handsets which incorporates AMOLED flexible display technology during its keynote presentation, the Youm and an unnamed Windows Phone 8 prototype device.Galaxy Note Edge,Samsung Galaxy S series devices.

LG Electronics and Samsung Electronics both introduced curved OLED televisions with a curved display at CES 2013 hours apart from each other.The Verge noted the subtle curve on 55" Samsung OLED TV allowed it to have a "more panoramic, more immersive viewing experience, and actually improves viewing angles from the side."
