flexible lcd displays factory

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.

A flexible display has longevity, which allows it to be used in many ways. For example, a flexible LED display can be used in indoor and outdoor, as well as other indoor and outdoor displays.

Since OLEDs are self-emissive displays, they don"t require backlight units like LCD displays. OLEDs have many outstanding characteristics such as thin and flexible form factor, lightweight, high image quality.

In particular, flexible OLED displays, which use flexible substrates such as polyimide instead of glass, are foldable or rollable, so demand is increasing mainly for mobile devices.

A backplane consisting of TFTs (thin film transistor circuit) and banks (partition wall for an organic light emitting layer) is formed on a flexible substrate.

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.

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.

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.

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.

Electronics on Plastic by Laser Release (EPLaR) is a method for manufacturing flexible electrophoretic displays using conventional AM-LCD manufacturing equipment, avoiding the need to build new factories. The technology can also be used to manufacture flexible OLED displays using standard OLED fabrication facilities.

The technology was developed by Philips Research and uses standard display glass as used in TFT-LCD processing plants. It is coated with a layer of polyimide using a standard spin-coating procedure used in the production of AM-LCD displays. This polyimide coating can now have a regular TFT matrix formed on top of it in a standard TFT processing plant to form the plastic display, which can then be removed using a laser to finish the display and the glass reused, thus lowering the total cost of manufacture.

The EPLaR process is licensed by Philips for use by Taiwan"s Prime View International in its TFT manufacturing plants for manufacture of flexible plastic displays.

The present disclosure relates to liquid crystal display technology, and more particularly to a manufacturing method of flexible display panels, a flexible glass substrate, and a flexible display panel.

Flexible display devices are also called as roll-up displays, which are display devices that may be arbitrarily bent and deformed and are made by flexible materials. The flexible displays may include e-paper, flexible liquid crystal devices, and Organic Light-Emitting Diode (OLED) displays, and are characterized by attributes such as light, small, thin, portable, anti-high and low temperature, anti-vibration, and may be well adapted to environment.

The OLED devices include the attributes such as self-luminescent, high brightness, wide viewing angle, high brightness, flexible and low power consumption, and are widely adopted by panels of cellular phones, computer, and televisions. The OLED display technology adopts very thin organic material emitting layer and flexible substrate. When current passes by, the organic material may emit lights. However, as the organic material may react with water and oxygen, water vapors and oxygen may damage the organic materials and the luminescent performance may be affected. Thus, flexible OLED displays are demanded to include good flexible and barrier property subject to the water and the oxygen.

Currently, the manufacturing method of flexible OLED devices may adopt the plastic substrate of polymer to form an organic film on the plastic substrate and to form a TFT and OLED device layer. In the end, the organic/inorganic materials are stacked to form a thin film package. However, most of the plastic substrate of polymer material are fragile to the high-temperature process. In addition, the requirement of forming the inorganic thin film having enough water-blocking capability increases the difficulty of the manufacturing process. Another solution is to adopt the flexible glass substrate. The flexible glass substrate owns a better surface characteristics and has excellent high temperature performance. In addition, the water-blocking capability of the flexible glass substrate is good, and thus the inorganic thin film is not needed, which simplifies the manufacturing process. However, the flexible glass substrate is fragile. Not only the quality of the product is affected, but also the yield rate and the application of the products are limited. SUMMARY

The object of the invention is to provide a manufacturing method of flexible display panels, a flexible glass substrate, and a flexible display panel to avoid the performance issue caused by the fragile flexible glass substrate.

In one aspect, a manufacturing method of flexible display panels includes: forming a TFT layer at one side of a flexible glass substrate; forming a polymer enhanced layer at the other side of the flexible glass substrate; curing the polymer enhanced layer; forming a display layer on the TFT layer; and forming an encapsulation layer on the side of the flexible glass substrate where the TFT layer is located.

In another aspect, a flexible display panel includes: a TFT layer, a display layer, an encapsulation layer and a flexible glass substrate; and wherein a polymer enhanced layer is formed at one side of the flexible glass substrate, and the TFT layer is arranged at the other side of the flexible glass substrate opposite to the polymer enhanced layer, the display layer is arranged on the TFT layer, and an encapsulation layer is arranged on the side of the flexible glass substrate where the TFT layer is located.

In view of the above, the polymer enhanced layer at one side of the flexible glass substrate. As the polymer material owns the attributes such as strong flexibility, high compressive resistance, and high mechanical strength, these prevent the stress from being centralized so as to overcome the fragile issue of flexible glass substrate. In addition, the compressive strength of the flexible glass substrate is enhanced. As such, the attributes of the flexible glass including anti-high-temperature, good surface characteristics, and good water blocking capability are achieved. At the same time, the flexibility and high pressure resistance are obtained. Further, the encapsulation efficiency and the display performance of the flexible display panel are enhanced. Also, by configuring the polymer enhanced layer at one side of the flexible glass substrate, there are a variety of methods may be selected in the subsequent process. BRIEF DESCRIPTION OF THE DRAWINGS

FIGS. 1 and 2 illustrate the manufacturing method of the flexible display panel in accordance with one embodiment. The method includes the following steps.

The flexible glass substrate 10 may be a thin and transparent glass, which may be bent easily by human. The thin film transistor (TFTs) are configured for driving liquid crystal pixels on the panel.

The glass is a typical brittle material. Although the flexible glass may be bent, but the compression strength of the flexible glass is still low. Defects exist in the surface and the internal of the flexible glass, and crack may expand when being subject to external forces and environmental media.

Thus, by forming the polymer enhanced layer 12 at one side of the flexible glass substrate 10, the polymer enhanced layer 12 may be adhered to the 10 may be adhered to the flexible glass substrate 10. In this way, the flexibility of the polymer may enhance the performance of the flexible glass by increasing the anti-pressure capability.

In the present disclosure, the TFT layer 11 is formed at one side of the flexible glass substrate 10, and the polymer enhanced layer 12 is formed at the other side of the flexible glass substrate 10. This prevents the polymer enhanced layer 12 from being damaged by the TFT high-temperature manufacturing process. In addition, as no high-temperature manufacturing process is needed in the following process, the glass substrate and the polymer layer are prevented from being detached from each other due to different coefficients of expansion.

For instance, the polymer enhanced layer 12 may be PET, PI, or epoxy resin. For instance, PET may be polyethylene terephthalate, which owns attributes such as great mechanical property, high impact strength, good folding resistance, anti-high and low temperature, and low penetration rate with respect to gas and vapors. That is, the PET owns great performance with respect to oxygen, water, oil, and smell. In addition, the transparency of PET is high, which may block ultraviolet rays. Thus, by adopting the PET to be the polymer enhanced layer 12, not only the anti-pressure capability of the flexible glass may be enhanced, but also the performance of the flexible glass substrate 10 subject to water, high and low temperature may also be enhanced. In addition, the transparency and gloss of the flexible glass are not affected. Polyimide (PI) owns the attributes such as anti-abrasion, anti-high-temperature, and high impact resistance. Epoxy resin owns good physical and chemical performance. For instance, epoxy resin owns great bonding strength toward metal or nonmetal. In addition, epoxy resin owns good flexibility. It can be understood that the polymer enhanced layer 12 may be other polymer materials having good flexibility, high adhesivity, and high compressive resistance.

The polymer enhanced layer 12 may be cured by, such as, backing or by radiation via UV rays. In the embodiment, the polymer enhanced layer 12 may be PET on the flexible glass substrate 10, and is cured by UV rays

In the embodiment, the display layer 13 is the OLED layer. In particular, the OLED layer may include an anode metal layer, an organic layer and a cathode metal layer. OLED may be formed by ink-jet printing or vacuum evaporation, and the OLED layer is formed on the TFT layer 11 by film formation. The ink-jet printer may include system controller, inkjet controller, spray nozzle, and driving mechanism of print substrate. The organic objects are ejected out, when being controlled by the inkjet controller, and then are printed on the print substrate. It can be understood the display layer 13 may be the corresponding display panel for the flexible display e-paper or flexible display panel.

In block S104, an encapsulation layer 14 is formed at one side of the flexible glass substrate 10 where the TFT layer 11 is located. As the blocking capability of the flexible glass substrate 10 subject to the water and oxygen is relatively low when being compared with the rigid glass substrate, the flexible glass substrate 10 has to be effectively encapsulated. In particular, the encapsulation layer 14 may be formed by surface encapsulation or thin-film encapsulation, wherein the thin-film encapsulation may include stacking the inorganic or organic materials. The packing material may be SiNx/SiOC/SiNx. The method is accomplished by depositing the thin film having the blocking capability with respect to water and oxygen when the temperature is low. Regarding the surface encapsulation, solid glue having high water-blocking capability is adhered to the encapsulation cover, and then is bonded with the substrate to accomplish the encapsulation.

In view of the above, the polymer enhanced layer at one side of the flexible glass substrate. As the polymer material owns the attributes such as strong flexibility, high compressive resistance, and high mechanical strength, these prevent the stress from being centralized so as to overcome the fragile issue of flexible glass substrate. In addition, the compressive strength of the flexible glass substrate is enhanced. As such, the attributes of the flexible glass including anti-high-temperature, good surface characteristics, and good water blocking capability are achieved. At the same time, the flexibility and high pressure resistance are obtained. Further, the encapsulation efficiency and the display performance of the flexible display panel are enhanced. Also, by configuring the polymer enhanced layer at one side of the flexible glass substrate, there are a variety of methods may be selected in the subsequent process.

FIGS. 2 and 3 are flowcharts illustrating the manufacturing method of the flexible display panels in accordance with another embodiment. The method includes the following steps.

In block S201, a PI enhanced layer is formed at the other side of the flexible glass substrate. In particular, the PI enhanced layer is formed by sputtering.

In block S204, an encapsulation layer is formed at one side of the flexible glass substrate where the TFT layer is located. In the embodiment, the encapsulation is formed by SiNx/SiOC/SiNx via the thin-film encapsulation.

The display layer 43 is arranged on the TFT layer 41. The encapsulation layer 44 is arranged at one side of the flexible glass substrate 40 where the TFT layer 41 is located.

Specifically, the polymer enhanced layer 42 may be PET, PI, or epoxy resin. The polymer enhanced layer 42 may be formed on the flexible glass substrate 40 by one of the spin-coating, sputtering, spray coating and screen printing. The display layer 43 may be the OLED layer.

Flat panel displays use different backplane technologies. Small and medium OLEDs for mobile phones use a low temperature polysilicon (LTPS) backplane which is created by laser annealing amorphous silicon (a-Si). OLED TVs use a metal oxide backplane. Both backplanes use deposited thin films which must be highly uniform and contamination free to maximize electrical performance. The OLEDs are evaporated or deposited and encapsulated to reduce degradation caused by water vapor and oxygen exposure. Encapsulation uses either strengthened glass or thin films, depending on whether the OLED is rigid or flexible. Dissimilarity of materials within the rigid and flexible stacks make cutting and singulation of individual display devices a challenge. The highly complex nature of this process can induce defects, decreasing throughput and yield.

Our industrial femtosecond and picosecond display manufacturing lasers are excellent for glass and film cutting. For cover glass and rigid OLED, they provide flexible pulse and burst control with precision, resulting in a micro-crack, chip-free edge, making the glass stronger and less likely to break if dropped. This reduces the need for post-cut polishing, increasing throughput by reducing the number of manufacturing process steps. For flexible OLEDs, Spectra-Physics lasers with short pulse widths create a minimal heat affected zone and provide a clean cut through layers of dissimilar materials including various thin films, PET, and adhesives. Increased throughput is achieved from higher output power that speeds up the cutting process. The narrow kerf or cut and the low heat affected zone means more parts can be cut out of the same material.
