The team focused on two key innovations for achieving highly flexible designs. The first is the recent development of optically rewritable LCDs. Like conventional LCD displays, the display is structured like a sandwich, with a liquid crystal filling between two plates. Unlike conventional liquid crystals where electrical connections on the plates create the fields required to switch individual pixels from light to dark, optically rewritable LCDs coat the plates with special molecules that realign in the presence of polarized light and switch the pixels. This removes the need for traditional electrodes, reduces the structure"s bulk and allows more choices in the type and thickness of plates. Consequently, optically rewritable LCDs are thinner than traditional LCDs, at less than half a millimeter thick, can be made from flexible plastic, and weigh only a few grams. "It"s only a little thicker than paper," said Jiatong Sun, a co-author from Donghua University in China.

Optically rewritable LCDs are durable and cheap to manufacture because of their simple structure. Moreover, like an electronic paper screen in an e-book, energy is only required to switch display images or text. Therefore, running costs are low because these new LCDs don"t need power to sustain an image once it is written on the screen.

The second innovation involves the spacers that create the separation of the plastic or glass plates. "We put spacers between glass layers to keep the liquid crystal layer uniform," Sun said. Spacers are used in all LCDs to determine the thickness of the liquid crystal. A constant thickness is necessary for good contrast ratio, response time and viewing angle. However, when plates bend, it forces the liquid crystal away from the impact site and leaves sections of the screen blank and so alterations in spacer design are critical to prevent liquid crystal in flexible LCDs from moving excessively. Developing a flexible design that overcomes this barrier has proven challenging.

The researchers tried three different spacer designs and found that a meshlike spacer prevented liquid crystal from flowing when their LCD was bent or hit. This innovation enabled them to create the first flexible optically rewritable LCD.

An additional innovation involved improved color rendering. The scientists report that until this study, optically rewritable LCDs had only been able to display two colors at a time. Now, their optically rewritable LCD simultaneously displays the three primary colors. They achieved this by placing a special type of liquid crystal behind the LCD, which reflected red, blue and green. To make this into a commercial product, Sun wants to improve the resolution of the flexible optically rewritable LCD.

FlexEnable’s glass-free organic LCD (OLCD) delivers high-brightness, long lifetime flexible displays that are low cost and scalable to large areas, while also being thin, lightweight and shatterproof.

OLCD is a plastic display technology with full colour and video-rate capability. It enables product companies to create striking designs and realise novel use cases by merging the display into the product design rather than accommodating it by the design.

Unlike flexible OLED displays, which are predominantly adopted in flagship smartphones and smartwatches, OLCD opens up the use of flexible displays to a wider range of mass-market applications. It has several attributes that make it better suited than flexible OLED to applications across large-area consumer electronics, smart home appliances, automotive, notebooks and tablets, and digital signage.

OLCD can be conformed and wrapped around surfaces and cut into non-rectangular shapes during the production process. Holes can be also added to fit around the functional design of the system – for example around knobs and switches.

As with glass-based LCD, the lifetime of OLCD is independent of the display brightness, because it is achieved through transmission of a separate light source (the backlight), rather than emission of its own light. For example OLCD can be made ultra-bright for viewing in daylight conditions without affecting the display lifetime – an important requirement for vehicle surface-integrated displays.

OLCD is the lowest cost flexible display technology – it is three to four times lower cost that flexible OLED today. This is because it makes use of existing display factories and supply chain and deploys a low temperature process that results in low manufacturing costs and high yield.

Unlike other flexible display approaches, OLCD is naturally scalable to large sizes. It can be made as small or as large as the manufacturing equipment used for flat panel displays allows.

The flexibility of OLCD allows an ultra-narrow bezel to be implemented by folding down the borders behind the display. This brings huge value in applications like notebooks and tablets where borderless means bigger displays for the same sized device. The bezel size allowed by OLCD is independent of the display size or resolution. In addition, OLCD can make a notebook up to 100g lighter and 0.5mm thinner.

OLCD is the key to the fabrication of ultra-high contrast dual cell displays with true pixel level dimming, offering OLED-like performance at a fraction of the cost. The extremely thin OLCD substrate brings advantages in cost, viewing angle and module thickness compared to glass displays. At the same time OLCD retains the flexibility required for applications such as surface-integrated automotive displays.

Due to its unique properties, OLCD has the potential to transform how and where displays are used in products. The videos below give a glimpse into this innovative technology.

OLCD brings the benefits of being thin, light, shatterproof and conformable, while offering the same quality and performance as traditional glass LCDs. The mechanical advantages of plastic OLCD over glass LCD are further enhanced by the technology’s excellent optical performance, much of which originates from the extreme thinness of plastic TAC substrates compared to glass.

If you’ve ever begun searching for a new computer screen, chances are you’ve probably come across the term IPS. It’s at this point that you may be asking yourself, what is an IPS monitor? And how do I know if an IPS monitor is right for me?

Below we’ll take a look at how IPS, TN, and VA monitors affect screen performance and do some handy summaries of strengths, weaknesses, and best-case uses for each type of panel technology.

With regard to gaming, some criticisms IPS monitors include more visible motion blur coming as a result of slower response times, however the impact of motion blur will vary from user to user. In fact, mixed opinions about the “drawbacks” of IPS monitor for gaming can be found all across the web. Take this excerpt from one gaming technology writer for example: “As for pixel response, opinions vary. I personally think IPS panels are quick enough for almost all gaming. If your gaming life is absolutely and exclusively about hair-trigger shooters, OK, you’ll want the fastest response, lowest latency LCD monitor. And that means TN. For the rest of us, and certainly for those who place even a modicum of importance on the visual spectacle of games, I reckon IPS is clearly the best panel technology.” Read the full article here.

TN monitors, or “Twisted Nematic” monitors, are the oldest LCD panel types around. TN panels cost less than their IPS and VA counterparts and are a popular mainstream display technology for desktop and laptop displays.

Despite their lower perceived value, TN-based displays are the panel type preferred by competitive gamers. The reason for this is because TN panels can achieve a rapid response time and the fastest refresh rates on the market (like this 240Hz eSports monitor). To this effect, TN monitors are able to reduce blurring and screen tearing in fast-paced games when compared to an IPS or VA panel.

In fact, TN monitor can sometimes be easily identified by the color distortion and contrast shifting that’s visible at the edges of the screen. As screen sizes increase, this issue becomes even more apparent as reduced color performance can even begin to be seen when viewing the screen from a dead-center position.

These high-end VA-type monitors rival IPS monitors as the best panel technology for professional-level color-critical applications. One of the standout features of VA technology is that it is particularly good at blocking light from the backlight when it’s not needed. This enables VA panels to display deeper blacks and static contrast ratios of up to several times higher than the other LCD technologies. The benefit of this is that VA monitors with high contrast ratios can deliver intense blacks and richer colors.

There is another type of panel technology that differs from the monitor types discussed above and that is OLED or “Organic Light Emitting Diode” technology. OLEDs differ from LCDs because they use positively/negatively charged ions to light up every pixel individually, while LCDs use a backlight, which can create an unwanted glow. OLEDs avoid screen glow (and create darker blacks) by not using a backlight. One of the drawbacks of OLED technology is that it is usually pricier than any of the other types of technology explained.

When it comes to choosing the right LCD panel technology, there is no single right answer. Each of the three primary technologies offers distinct strengths and weaknesses. Looking at different features and specs helps you identify which monitor best fits your needs.

LCD or “Liquid Crystal Display” is a type of monitor panel that embraces thin layers of liquid crystals sandwiched between two layers of filters and electrodes.

While CRT monitors used to fire electrons against glass surfaces, LCD monitors operate using backlights and liquid crystals. The LCD panel is a flat sheet of material that contains layers of filters, glass, electrodes, liquid crystals, and a backlight. Polarized light (meaning only half of it shines through) is directed towards a rectangular grid of liquid crystals and beamed through.

Note: When searching for monitors you can be sure to come across the term “LED Panel” at some point or another. An LED panel is an LCD screen with an LED – (Light Emitting Diode) – backlight. LEDs provide a brighter light source while using much less energy. They also have the ability to produce white color, in addition to traditional RGB color, and are the panel type used in HDR monitors.

Early LCD panels used passive-matrix technology and were criticized for blurry imagery. The reason for this is because quick image changes require liquid crystals to change phase quickly and passive matrix technology was limited in terms of how quickly liquid crystals could change phase.

Thanks to active-matrix technology, LCD monitor panels were able to change images very quickly and the technology began being used by newer LCD panels.

When an LCD panel is subjected to pure bending, for example during strength measurement or proof testing, the question arises “does it behave as a monolith of twice the substrate thickness?" or "does it behave as two independent substrates?”. Both theory and experiment suggest that the panel behavior depends on how its edges are held together (i.e. well bonded or loosely held together). Indeed, the former renders the panel nearly twice as strong and four fold as stiff as the latter. This paper will provide the analysis of the bending behavior of a two-layer laminate using St. Venant flexure theory. Experimental data, using strain gages, will demonstrate that an LCD panel can behave either as a monolith of twice the substrate thickness or two independent substrates depending on how its four edges are held together in the support structure including the bezel. The paper derives appropriate equations for computing panel strength when it is bent to constant curvature or when its specimens are flexed in 4-point bending for bothi) well bonded edges and ii) loosely held edges.

This paper provides general guidelines and watch outs while conducting strength testing on LCD glass. Importance of failure modes, large deflections, membrane stresses, failure locations, device design, fatigue, fractography and strain gauging are discussed in this paper. It also gives an example on why panels cannot be treated as monolithic glass when calculating the strength

The feasibility of using Corning’s edge strength measurement system (ESMS) for ultra-thin LCD panels has been demonstrated. Panels were used to validate the load-to-stress correlation: digital image correlation, finite element analysis and mirror radius measurement all showed good agreement, supporting the robustness of the strength measurement. The edge strength of panels was measured by both static and dynamic ESMS. Test results revealed that dynamic ESMS is advantaged over static in better capturing the relevant flaw population owing to its larger test area. Accurate edge strength measurement via ESMS coupled with selective fracture analysis on the weakest flaws will assist in improving the edge strength of ultra-thin LCD panels.

The four-point bend test is used extensively to measure the edge (and surface) strength of AMLCD displays both in panel form and single substrate. The subtleties of four-point bend test for AMLCD panel applications and how one might use additional techniques, such as strain gage, finite element modeling and failure mode analysis, to better understand the data generated, are investigated. This paper attempts to show the following: i) the standard four-point bend equation (FIgure 1) is not applicable to thin AMLCD panels, ii) the edges and surface experience dfiferent stress, iii) stresses can be quantified by knowing break location and the appropriate strain level and iv) failure mode analysis can support the strain analysis and provide valuable information to the experimenter.

Traditional testing methodologies (four point bend and three point bend) have limited effectiveness as panel thicknesses decrease due to a variety of interconnected factors. This limited effectiveness impacts the ability to make reliability predictions based on edge strength measurements. This paper provides an improved methodology for testing the edge strength of ultra-thin panels for reliability predictions through a system of rollers strategically placed only at the edge of the glass panel.

The biaxial strength using ring-on-ring (ROR) test and uniaxial strength using 4-point bend test (4PB) were measured for 13.3” panels with substrate thicknesses ranging from 0.25 mm to 0.5 mm. The effect of the thinning process was quantified by this data, along with identifying break sources using fractography. Strain gages were used to convert failure load to strength.

As display technology improves, our ability to create thinner, higher-resolution displays increases. Five years ago you would have been hard-pressed to find any displays less than 5mm thick, but now ultra-thin displays appear more frequently in consumer markets.

We"ve compiled this list of our thinnest displays available. You will find some amazingly thin OLED displays, the thinnest ePaper modules as well as a couple of slim OLEDs and even a TFT LCD that"s less than 2mm thick.

ePaper in general is one of the thinnest display technologies. Most of our ePaper display modules are less than 2mm! Click to see all of our ePaper display modules. The absolute thinnest ePaper we have is an amazing 0.3mm thick!!

OLED displays have been getting thinner over time, with many under 5mm. Our thinnest OLED display is as thin as our thinnest ePaper at an amazing 0.3mm!! For reference graphite in a mechanical pencil is often 0.7mm - more than twice as thick!

Finding standard LCDs or TFTs that are smaller than 2mm remains difficult. We have a few thin LCDs and they"re very popular! Probably not just because they"re thin. Maybe it"s because they are beautiful as well?

Finally, a user-friendly paperless device. Digital documents are right there in portrait mode for quick cross-referencing and editing is made easy with copy-paste functionality across different screens.

Many e-readers, devices meant to replace traditional books, utilize electronic paper for their displays in order to further resemble paper books; one such example is the Kindle series by Amazon.

Electronic paper, also sometimes electronic ink, e-ink or electrophoretic display, are display devices that mimic the appearance of ordinary ink on paper.flat panel displays that emit light, an electronic paper display reflects ambient light like paper. This may make them more comfortable to read, and provide a wider viewing angle than most light-emitting displays. The contrast ratio in electronic displays available as of 2008 approaches newspaper, and newly (2008) developed displays are slightly better.

Many electronic paper technologies hold static text and images indefinitely without electricity. Flexible electronic paper uses plastic substrates and plastic electronics for the display backplane. Applications of electronic visual displays include electronic shelf labels and digital signage,smartphone displays, and e-readers able to display digital versions of books and magazines.

Electronic paper was first developed in the 1970s by Nick Sheridon at Xerox"s Palo Alto Research Center.Gyricon, consisted of polyethylene spheres between 75 and 106 micrometers across. Each sphere is a Janus particle composed of negatively charged black plastic on one side and positively charged white plastic on the other (each bead is thus a dipole).polyvinylidene fluoride (PVDF) as the material for the spheres, dramatically improving the video speed and decreasing the control voltage needed.

An electrophoretic display - also known as an EPD - are typically addressed using MOSFET-based thin-film transistor (TFT) technology. TFTs are requiredactive matrix displays used in the Amazon Kindle, Barnes & Noble Nook, Sony Reader, Kobo eReader, and iRex iLiad e-readers. These displays are constructed from an electrophoretic imaging film manufactured by E Ink Corporation. A mobile phone that used the technology is the Motorola Fone.

Electrophoretic displays can be manufactured using the Electronics on Plastic by Laser Release (EPLaR) process developed by Philips Research to enable existing AM-LCD manufacturing plants to create flexible plastic displays.

In the 1990s another type of electronic ink based on a microencapsulated electrophoretic display was conceived and prototyped by a team of undergraduates at MITBarrett Comiskey, Joseph Jacobson, Jeremy Rubin and Russ Wilcox co-founded E Ink Corporation in 1997 to commercialize the technology. E ink subsequently formed a partnership with Philips Components two years later to develop and market the technology. In 2005, Philips sold the electronic paper business as well as its related patents to Prime View International."It has for many years been an ambition of researchers in display media to create a flexible low-cost system that is the electronic analog of paper. In this context, microparticle-based displays have long intrigued researchers. Switchable contrast in such displays is achieved by the electromigration of highly scattering or absorbing microparticles (in the size range 0.1–5 μm), quite distinct from the molecular-scale properties that govern the behavior of the more familiar liquid-crystal displays. Micro-particle-based displays possess intrinsic bistability, exhibit extremely low power d.c. field addressing and have demonstrated high contrast and reflectivity. These features, combined with a near-lambertian viewing characteristic, result in an "ink on paper" look. But such displays have to date suffered from short lifetimes and difficulty in manufacture. Here we report the synthesis of an electrophoretic ink based on the microencapsulation of an electrophoretic dispersion. The use of a microencapsulated electrophoretic medium solves the lifetime issues and permits the fabrication of a bistable electronic display solely by means of printing. This system may satisfy the practical requirements of electronic paper."

One early version of the electronic paper consists of a sheet of very small transparent capsules, each about 40 micrometers across. Each capsule contains an oily solution containing black dye (the electronic ink), with numerous white titanium dioxide particles suspended within. The particles are slightly negatively charged, and each one is naturally white.liquid polymer, sandwiched between two arrays of electrodes, the upper of which is transparent. The two arrays are aligned to divide the sheet into pixels, and each pixel corresponds to a pair of electrodes situated on either side of the sheet. The sheet is laminated with transparent plastic for protection, resulting in an overall thickness of 80 micrometers, or twice that of ordinary paper.

The colors are cyan, magenta, and yellow, which is a subtractive system, comparable to the principle used in inkjet printing. Compared to LCD, brightness is gained because no polarisers are required.

The technology used in electronic visual displays that can create various colors via interference of reflected light. The color is selected with an electrically switched light modulator comprising a microscopic cavity that is switched on and off using driver integrated circuits similar to those used to address liquid-crystal displays (LCD).

Other research efforts into e-paper have involved using organic transistors embedded into flexible substrates,triads, typically consisting of the standard cyan, magenta and yellow, in the same way as CRT monitors (although using subtractive primary colors as opposed to additive primary colors). The display is then controlled like any other electronic color display.

Several companies are simultaneously developing electronic paper and ink. While the technologies used by each company provide many of the same features, each has its own distinct technological advantages. All electronic paper technologies face the following general challenges:

Electronic ink can be applied to flexible or rigid materials. For flexible displays, the base requires a thin, flexible material tough enough to withstand considerable wear, such as extremely thin plastic. The method of how the inks are encapsulated and then applied to the substrate is what distinguishes each company from others. These processes are complex and are carefully guarded industry secrets. Nevertheless, making electronic paper is less complex and costly than LCDs.

There are many approaches to electronic paper, with many companies developing technology in this area. Other technologies being applied to electronic paper include modifications of liquid-crystal displays, electrochromic displays, and the electronic equivalent of an Etch A Sketch at Kyushu University. Advantages of electronic paper include low power usage (power is only drawn when the display is updated), flexibility and better readability than most displays. Electronic ink can be printed on any surface, including walls, billboards, product labels and T-shirts. The ink"s flexibility would also make it possible to develop rollable displays for electronic devices.

In December 2005, Seiko released the first electronic ink based watch called the Spectrum SVRD001 wristwatch, which has a flexible electrophoretic displayPebble smart watch (2013) uses a low-power memory LCD manufactured by Sharp for its e-paper display.

In 2004, Sony released the Librié in Japan, the first e-book reader with an electronic paper E Ink display.Sony Reader e-book reader in the USA. On October 2, 2007, Sony announced the PRS-505, an updated version of the Reader. In November 2008, Sony released the PRS-700BC, which incorporated a backlight and a touchscreen.

In late 2007, Amazon began producing and marketing the Amazon Kindle, an e-book reader with an e-paper display. In February 2009, Amazon released the Kindle 2 and in May 2009 the larger Kindle DX was announced. In July 2010 the third-generation Kindle was announced, with notable design changes.

In 2020, Onyx released the first frontlit 13.3 inch electronic paper Android tablet, the Boox Max Lumi. At the end of the same year, Bigme released the first 10.3 inch color electronic paper Android tablet, the Bigme B1 Pro. This was also the first large electronic paper tablet to support 4g cellular data.

Flexible display cards enable financial payment cardholders to generate a one-time password to reduce online banking and transaction fraud. Electronic paper offers a flat and thin alternative to existing key fob tokens for data security. The world"s first ISO compliant smart card with an embedded display was developed by Innovative Card Technologies and nCryptone in 2005. The cards were manufactured by Nagra ID.

On December 12, 2012, Yota Devices announced the first "YotaPhone" prototype and was later released in December 2013, a unique double-display smartphone. It has a 4.3-inch, HD LCD on the front and an electronic ink display on the back.

E-paper based electronic shelf labels (ESL) are used to digitally display the prices of goods at retail stores. Electronic-paper-based labels are updated via two-way infrared or radio technology.

E-paper displays at bus or trams stops can be remotely updated. Compared to LED or liquid-crystal displays (LCDs), they consume lower energy and the text or graphics stays visible during a power failure. Compared to LCDs, it is well visible also under full sunshine.

Typically, e-paper electronic Tags integrate e-ink technology with wireless interfaces like NFC or UHF. They are most commonly used as employees" ID cards or as production labels to track manufacturing changes and status. E-Paper Tags are also increasingly being used as shipping labels, especially in the case of reusable boxes.

An interesting feature provided by some e-paper Tags manufacturers is batteryless design. This means that the power needed for a display"s content update is provided wirelessly and the module itself doesn"t contain any battery.
