SEOUL, Korea (Jan. 3, 2022) – LG Display, the world’s leading innovator of display technologies, announced today that it will be showcasing its latest innovations at CES 2022.

Under the slogan of “Display Your Universe”, LG Display will be introducing innovative solutions that not only cater to people’s constantly-evolving needs and various lifestyles, but also propose new experiences set to redefine the way people do ordinary tasks in their daily lives.

The company will be highlighting its differentiated and cutting-edge technologies to enhance people’s lives – including ‘OLED.EX’, the next phase of OLED’s evolution; Transparent and Flexible OLED solutions that break away from spatial limitations; ‘IPS Black’, its new high-end LCD technology for IT products; new Gaming OLED displays, as well as a 17-inch Foldable OLED display for laptops.

This year’s showstopper is LG Display’s brand-new OLED TV display ‘OLED.EX’, which will further improve picture quality to provide an upgraded viewing experience.

The next-generation OLED.EX display implements LG Display’s deuterium and personalized algorithm-based ‘EX Technology’. Compared to conventional OLED displays, brightness is boosted by 30 percent while bezel width is reduced by 30 percent from 6mm to 4mm based on 65-inch OLED displays, thereby enhancing the OLED panels’ overall picture quality and heightening the design’s premium aesthetic.

Starting from the second quarter of 2022, LG Display will integrate its groundbreaking OLED.EX technology into every OLED TV display it produces to ensure people can enjoy next-level immersive viewing experiences.

In addition to OLED.EX, LG Display will be unveiling Transparent OLED solutions developed to further seamlessly bridge the gap between online and physical spaces. Leveraging the advantages of OLED’s self-emissive nature, the company’s Transparent OLED boasts high transparency enough to replace regular glasses as well as the ability to display graphic effects and information in excellent picture quality. In addition, considering that Transparent OLED displays flaunt a slim design and light weight, they can be widely utilized for various industries such as transportation and construction.

The company is demonstrating the benefits of Transparent OLED through an array of unique and eye-catching products including ‘Shopping Managing Showcase’ and ‘Show Window’ for shopping malls, as well as ‘Smart Window’ for offices, Transparent OLED for subway trains, and ‘OLED Shelf’ that can transform any home interior into a living space.

LG Display is set to unveil its ‘Shopping Managing Showcase,’ a Transparent OLED display fitted inside a wooden display stand, which will reinvent the offline shopping experience. Ideal for luxurious department stores, the Shopping Managing Showcase can display eye-catching visual content on the screen that harmonizes with the products on display behind to better grab the attention of shoppers and elevate the ambience of the place.

Another example of how LG Display is redefining the shopping experience is its newly upgraded ‘Show Window’. Originally having comprised a single Transparent OLED display, the Show Window now utilizes four 55-inch Transparent OLED displays, maximizing the advertising potential of window displays by delivering a more unique and informative shopping experience.

When it comes to the office, LG Display will be showcasing its ‘Smart Window’ which is specially designed for the office of the future. By applying this Transparent OLED technology to conference room windows, the advanced Smart Window can help professional teams maximize their productivity by transforming into an expansive screen for video conferencing and presentations without compromising the open view of a normal glass window.

LG Display will be also showcasing Transparent OLED for subway trains. Designed to replace existing subway train windows, the Transparent OLED displays provide useful information regarding subway schedules, weather, and news all the while giving passengers a clear view of the outside scenery. When fully applied in the transportation and mobility industry, the Transparent OLEDs are expected to provide augmented reality-like experiences such as displaying advertisements or relevant information regarding famous landmarks in real-time as the train is passing by.

To modernize home life, LG Display will be introducing its latest concept, ‘OLED Shelf,’ which combines two Transparent OLED displays, one above the other, and seamlessly blends into any living room decoration while adding a touch of elegance as it is hanging off from the shelf on the wall. The innovative OLED Shelf is perfect for displaying TV shows or gallery paintings while running in its Always on Display Mode, further demonstrating Transparent OLED displays’ ability to transform any home interior into a living space that exudes modernity.

Moreover, LG Display will be showcasing Gaming OLED displays. Its Gaming OLED range, which has already received high praise from the gaming community, flaunts a response time 10 times faster than conventional LCD counterparts without irritating ghosting effects, to allow the user to enjoy excellent image quality and an immersive gameplay to date. The company’s highly-touted Gaming OLED also provides an even higher level of eye comfort for long gaming sessions without the sore and fatigued eyes during and afterwards. LG Display will bring its 48-inch and 42-inch Gaming OLED displays to the market in 2022.

LG Display will be showing off its 17-inch Foldable OLED for laptops. The display is almost entirely crease-free at the point of folding, letting users enjoy one device in various ways and forms – from a tablet to a laptop to even a portable monitor. What’s more, the screen is also equipped with the company’s touchscreen solutions that enable people to use the screen with either a pen or one’s fingers depending on their preference or the task being undertaken.

For the first time ever, LG Display will introduce ‘IPS Black’, a high-end and premium LCD technology for IT products. The IPS Black displays boast a black level 35 percent deeper than existing IPS products, which enables extreme clarity and precise color accuracy, essential for professions where success lies in the details. What’s more, the IPS Black significantly lowers the level of blue light and flaunts a nearly-borderless design on all sides of the display that heightens immersion and looks great anywhere. LG Display will be introducing its IPS Black technology at CES 2022 through a 27-inch UHD monitor.

LG Display’s cutting-edge and innovative display products will be showcased through its virtual exhibition on CES official website only for its customers.

LG Display has come up with more uses for transparent screens with its innovative new concepts that will be on display at CES 2022: the OLED Shelf, Shopping Managing Showcase, Show Window, and Smart Window. The company is not to be confused with LG Electronics, as LG Display simply creates concepts that other companies can adopt and introduce to the market.

Its OLED Shelf, visible at the top of this story, consists of two 55-inch transparent OLED displays mounted on top of one another, with a shelf at the very top. LG Display says it’s ideal for the living room, where it can display art, a TV show, or one on each of the two screens simultaneously. Always on Display Mode ensures that the screen can stay on all the time. If there was a piece of art on display, that image could stay put just like a painting, all while blending into the wall behind it.

There’s actually room for you to put an actualpainting behind the screens, too, which you’d be able to see when they’re off. LG’s also devised a motorized sheet of opaque material which rolls down like a projector screen to make their images more vibrant and less ethereal. (Images viewed on transparent screens can sometimes look ghostly.) The pedestal you see in the image above houses some of the electronics, and the screens take standard HDMI input.

While the OLED Shelf is built for the home, LG Display says its Shopping Managing Showcase is meant for “luxurious” department stores. A transparent OLED display is attached to a sleek wooden stand, and when placed in front of physical products, it looks like it could create a futuristic shopping experience. It adds an overlay to the items behind it, which means storeowners could add graphics that highlight certain parts of their products, or even use the display to provide funky visual effects. We saw a video where flowy graphics drew our eye to one of the perfume bottles in the display above, giving it a lustrous halo effect.

LG Display also gave us a glimpse of its Show Window, another business-focused model that consists of four 55-inch transparent OLED displays that could be used to play up products in window displays — instead of window decals, stores could add digital text, which can easily be changed at any time. The company says versions of it are already on display at the new Musinsa fashion store in Seoul, as well as art exhibitions at The Smithsonian and at 180 The Strand in London, inside some subway car windows in China and Japan, and a Bulgari fashion show.

The company also showed off its Smart Window, another transparent OLED screen that can be for video calls or presentations in the office, however, it didn’t provide any images of that display.

Since these transparent displays are just concepts, we probably won’t see many of them in the real world, but that doesn’t change the fact that they’re still pretty darn cool to look at — and LG Display says it’s ready to help customers produce some of them if they want. “If any of our customers want, we can provide [the OLED Shelf],” LG Display spokesperson Jean Lee tells The Verge, saying it’s ready for production. All of these displays consist of the same 55-inch 1080p transparent OLED panels with 40 percent transparency, which Lee says is on the company’s 8th generation display manufacturing process.

LG Display has been in the transparent display game for a while now, revealing its first flexible and see-through screen in 2014, and more recently, it showed off a transparent TV screen mounted to the foot of a bed. But it doesn’t just dabble in transparent screens — the company is also showcasing its half-moon-shaped chair with a built-in OLED screen at CES this year.

Transparent display technology surrounds us, even if we aren’t aware of it. In this article we look at transparent head-up displays, LCDs, OLEDs and transparent electroluminescent technology and delve into the pros and cons of the four main transparent technology displays.

However, if you think this is new technology, think again. While most transparent technology has come to the fore since the millennium, it was being used as far back as the mid-20th century.

In this article, we’re looking at four types of transparent tech which include typical projection head-up displays (HUDs), LCDs, OLEDs, and transparent electroluminescent displays (TASEL). We’ll look at the pros and cons of each and show you how transparent display technology plays an essential part in our working lives and free time. An explanatory

The first steps into creating transparent head-up displays can be traced back as far as 1937. However, it wasn’t until the 1950s, following perfections to the technology by the US and British Royal Navies, UK Ministry of Defence and, finally, the Royal Aircraft Establishment in 1958, that the first true projection ‘head-up display’ was incorporated into aircraft.

There is also an emerging technology calledTASEL, which makes it possible to laminate displays in glass and show information without a projection system. However, as this a different transparent technology, we’ll mention thislaterin the article.

The most common transparent projection HUD is a display composed by a piece of flat glass used to project images in front of the pilot. This allows the pilot to keep their head up (hence the name ‘head-up display’) so they’re not distracted by looking down at their control panel for information during flight.

Why have we included LCDs as a transparent display when, at first glance, they’re not truly transparent? In fact, we’re only able to see the information on our monitors, such as laptops, with the introduction of a backlight and a reflector shield.

Take these away and we see true transparency of the LCD display - which is something Samsung did in 2012 with the production of theirSamsung Transparent Smart Window.

LCDs are also one of the most popular screens on the market and this rise occurred early in the 21st century when liquid-crystal-display sets rocketed in popularity. In 2007, LCDs eclipsed sales of competing technologies like plasma, cathode ray tube, and rear-projection TVs.

They were thinner and lighter, easier to scale. And for the manufacturers, the cost of production was lower, so it’s easy to see how LCD displays quickly became a favorite with manufacturers and consumers.

Organic light-emitting diode displays, orOLEDsfor short, are a step up from LCDs when it comes to transparent technology. For starters, unlike LCDs, OLEDs do not require the use of a backlight or any other filters due to the use of pixels which produce their own light.

Lumineq’s Transparent Electroluminescent displays consist of a glass panel with a luminescent phosphorous layer and a circuit board. The circuit board contains the drive and controls which are connected directly to the glass panel making the panel light up.

The transparent electroluminescent displays are good solutions for transportation vehicles such as cars, buses, trucks, trains, trams, boats, and airplanes because they can be laminated in glass and turn windows/windshields into information and functional displays.

It’s viewable from all angles, is visible in all types of weather conditions and is theonlytransparent display capable of working in the most extreme environments, from the freezing temperatures of the Arctic winter to the blistering heat of a desert summer.

However, due to the limitation of monochromatic images, transparent electroluminescent displays shouldn’t be used as entertainment screens in vehicles - they should be used to display only the most critical information in the eye-line of the driver without distractions.

This comparison of different transparent display technologies is conducted by the Ph.D. reseracher Jose Rosa for theImmerSAFE project. The project stands for "IMMERSIVE VISUAL TECHNOLOGIES FOR SAFETY-CRITICAL APPLICATIONS".

Each transparent display has its positives and negatives, and they’re all fantastic ways to showcase transparent display technology at its best when applied in areas which suit their purpose perfectly.

Lumineq’s transparent electroluminescent displays are ideal in transportation vehicles, heavy machinery, such as tractors, and optical devices, like range-finders and night-vision goggles.

To read how in-glass technology is making giant strides in optical devices, read our post ‘Bring augmented reality to optical devices with transparent displays’, or to find out more about Lumineq"s transparent electroluminescent technology,contact ustoday.

As exciting as these unlimited possibilities are, they also create a new need for understanding and embracing the benefits of see-through displays. The eBook from below will provide you with ideas, inspiration, basic guidelines and industry examples for designing transparent displays for vehicles – from cars, tractors, and ships to aircraft.

Nothing screams future technology like transparent OLED screens, and LG Display has just revealed its latest concepts and prototypes for CES 2022, The Verge reported. All the concepts were created by LG Display (an independent sister company to LG Electronics) from 55-inch 1080p OLED panels with 40 percent transparency using its 8th-generation manufacturing process.

The most visually arresting model is the OLED Shelf that"s built from two 55-inch transparent OLED displays mounted one above the other and topped by a shelf. The idea is that you could display artwork on one screen and a description of the art below, for example. It also has a sheet of opaque material that can roll down like a shade to make the display more like a standard, non-transparent OLED. At the same time, if the screens are turned off and the opaque material rolled up, you"d be able to see objects behind the screen like actual paintings.

The other displays are designed more for signage and commercial clients. The Shopping Managing Showcase can be placed in front of physical products, adding graphics or effects like VFX smoke to enhance them. The Show Window, meanwhile, can display decal-like graphics in front of clothing or other products to make a showcase more attractive. LG Display said that versions of the latter are already being used at a fashion store in Seoul and even at the Smithsonian in Washington, DC.

LG Display already showed off a variety of curved displays, including a continuous screen that wraps around a stationary bike and a curved Media Chair concept. The new transparent displays are only concepts and prototypes, but it told The Verge that it could help customers develop them into products and that the OLED Shelf is ready for production.

One of the best parts of CES is getting a chance to hear from the companies behind the products we buy. A case in point is LG. Technically speaking, even though we buy LG OLED TVs from LG Electronics (LGE), the OLED panels inside those TV are engineered and manufactured by LG Display (LGD), a close, but separate division within the massive LG mothership. And LG Display is using CES 2021 to introduce a dizzying array of OLED innovations, from tiny, 20-inch TVs, to transparent panels that sit at the foot of your bed, to gaming displays that bend at the touch of a button.

Browse the TV section of any big box or online retailer and you’re bound to find OLED TVs from Sony, LG, and Vizio in 55- and 65-inch sizes. Dig a little deeper and you’ll find models in the 77-, 88-, and 48-inches sizes too. These are the meat and potatoes of the OLED TV world at the moment. But these sizes are just the tip of the OLED iceberg.

LG Display has plans for many more sizes. Variations on existing sizes will be 83-inch and 42-inch OLED panels, but there will also be much smaller ones “down to the 20-30-inch range,” according to an LGD press release. These tiny panels will be geared toward gaming, mobility, and personal display options.

Additional sizes of OLED displays are obviously beneficial when it comes to developing new TVs and other products, but there’s another reason why we’re beginning to see this increased variety. OLED displays aren’t created individually. At least, not anymore. They’re actually cut from a much larger mother sheet of OLED glass. One of these mother sheets is big enough to yield two 77-inch panels, but when you do that, there’s still quite a lot of material leftover — just not enough for a third or fourth panel of that size. But it is enough to yield two more panels at 48-inches each.

We tend to buy OLED TVs that are big, rigid affairs, but OLED technology has always been capable of assuming a flexible form. LG has shown off this capability at previous CES shows with both roll-up and roll-down OLED TVs. But what if, instead of using OLED’s flexibility to hide it away when not in use, we used it to morph a screen from flat to curved and back again, all at the push of a button?

That’s the premise behind LGD’s 48-inch Bendable Cinematic Sound OLED TV, a first-of-its-kind that the company is showing at CES this year. The prototype gaming-centric TV sits on a pedestal that doubles as Qi wireless charger and has a small button that is used to trigger the transformation between flat and curved.

Another innovation is LG’s Cinematic Sound OLED (CSO) technology which turns the entire OLED display into a speaker. LG isn’t the first to use this kind of technology — Sony introduced it on its Master Series OLED in 2019 under the name Acoustic Surface Audio+ — but it’s the first time we’ve seen it on such a small screen.

LGD is also using CES 2021 to showcase what you can do with OLED’s inherent ability to be transparent. One demonstration puts a transparent OLED display at the foot of a bed, inside a motorized frame that can lift the OLED display to its full height, or drop it down to any other level including fully recessed. Each height can be used to display different content from a simple clock to a detailed weather report.

Another example is the use of transparent OLED displays in restaurants to create versatile information screens that don’t add heaviness or block light.

A third example is a transparent OLED screen mounted in front of the window of a subway car. It can show route maps, weather, news, and advertising, without blocking the window’s view of the outside world.

LGD’s transparent OLEDs are 40% transparent and use the same CSO audio system as the bendable gaming TV so there’s no need for a separate speaker system.

LG has touted the many benefits of OLED displays over the years but it’s using CES 2021 to remind people that those benefits can expand to one’s personal health, too. LG Display’s OLED products have acquired certifications for low blue light emissions and flicker-free status from Germany’s TUV Rheinland and the U.S.-based safety agency UL (Underwriters Laboratories). By lowering the amount of blue light to the lowest level in the industry, the company has also obtained the “Eye-safe TV” certification from Eyesafe, an American eye health certification body, according to LGD’s press release.

LGD makes the highly relevant point that especially during a pandemic, when we are in front of our screens even more than normal, the quality of the display matters.

OLED technology enables thin, efficient and bright displays and lighting panels. OLEDs are currently used in many mobile devices, some TVs and lighting fixtures. OLED displays offer a better image quality compared to LCD or Plasma displays - and can also be made flexible and transparent.

Several companies develop transparent OLED (also referred to as T-OLED) technologies. While there"s no inherent technology barrier towards transparent OLED displays, finding actual applications for such displays is not easy.

As of 2021, LG Display is producing 55-inch transparent OLED panels (used mostly in signage and commercial settings) while other companies produce small (around 1-2 inch in size) transparent PMOLED display. In April 2013 we posted a review of Futaba"s 2" 160x128 transparent PMOLED panel - which could be an interesting read even if this specific display is no longer in production.

OLED technology can be used to make lighting panels - these are thin, area-lit and efficient lighting panels, that can be made transparent. Unlike displays, transparent OLED lighting panels have more immediate applications (embedded in windows, for example). In April 2012 we posted our hands-on review with a transparent Tabola OLED lighting panel sample. As the OLED lighting market in general is still at an early stage, we do not see actual adoption and production of transparent OLED lighting.

The report package also provides a complete list of transparent OLED developers and makers and their current (and future) products, and a lot more. Read more here!

The present invention relates generally to refrigerated display cases and refrigerator doors and, more particularly, to a refrigerator door with a transparent LCD panel. BACKGROUND OF THE INVENTION

The invention described herein includes the use of a transparent LCD glass panel as one of the panes in a three-pane unit, such as one used in an insulated glass refrigerator/freezer door.

Other types of refrigerator/freezer doors also require both power and data. For example, LED light fixtures mounted to the swinging door, LED illuminated marquee signs mounted inside the insulated glass assembly of the door, LCD displays mounted on the door handle, and transparent LCD glass panels with advertising all require both power and data. Most of these products require UL Class 2 low voltage (<60VDC), and many require a data supply, e.g. LCD displays with advertising pictures or videos requiring TCP/IP type data communications.

Generally, the invention is to use a transparent LCD glass panel as one of the panes in a three-pane unit, such as one used in an insulated glass refrigerator/freezer door. With the transparent LCD panel, a consumer can see the media shown on the LCD panel, but can also see inside the display case/refrigerator to view the contents therein. For example, transparent LCD panels are commercially available from Samsung. In a preferred embodiment, the LCD glass panel is used as the center panel. It is within the scope of the present invention to use the LCD glass panel as the inner or outer pane or to add the LCD glass panel as an additional pane. However, in a preferred embodiment, the LCD glass panel needs to be protected from impact and/or moisture damage. Mounting the panel externally may decrease visible transmittance and would also subject the panel to impact by shopping carts. Also, if the store ambient temperature and humidity are not properly controlled, the door can be subject to condensation which may damage the LCD panel or associated electronics. Mounting the panel inside the freezer (adjacent to the food) may cause condensation when the door is opened. Housing the LCD panel inside the hermetically sealed glass unit protects the panel from condensation damage. The associated electronics can also optionally be mounted inside the hermetically sealed glass assembly to protect them from condensation damage. In another embodiment, the electronics can be mounted outside the hermetically sealed glass assembly, such as in the rail of the door.

The door preferably includes the following distinctive features: (1) transparent LCD panel functioning as the center insulating pane of a three-pane low-temp glass freezer door to maximize visible transmittance while maintaining thermal insulating performance; (2) transparent LCD panel mounted between an inner and outer pane of glass to it protect from impact damage; (3) transparent LCD panel mounted inside the hermetically sealed glass unit to protect from moisture damage; (4) mounting the associated electronics, wires, and media player inside the sealed glass unit to protect it from moisture damage or inside the rail of the door; (5) using selectively decorated opaque areas (e.g. screen printing, dot matrix decorating, roller printing, ink jet printing, painting or the like) of the outer or inner pane of glass to hide the circuit boards around the LCD panel perimeter, the wires, and media player hardware of the door assembly, allowing the complete system to be conveniently housed inside the door. The “LCD door” can be used for advertising merchandise, nutritional value, pricing, etc.

In accordance with a first aspect of the present invention there is provided a door assembly that includes a single glass unit having at least first, second and third panels, a front surface, a rear surface, and an outside edge. At least one of the first, second or third panels is a transparent LCD panel on which media can be displayed. The single glass unit also includes a frame that at least partially surrounds the outside edge of the single glass unit, and electronic components in electrical communication with the LCD panel. In a preferred embodiment, the second panel comprises the transparent LCD panel and is positioned between the first and third panels and the first panel is spaced from the second panel by a first spacer and the third panel is spaced from the second panel by a second spacer. The first, second and third panels each have an outside edge and a length and a width. The length and the width of the second panel is smaller than the length and the width of the first and third panels, thereby defining a margin between the outer edge of the second panel and the outer edges of the first and third panels. The first panel is spaced from the third panel by a third spacer that is positioned within the margin.

In a preferred embodiment, the single glass unit includes insulation disposed within the margin and between the first and third panels and the second panel is hermetically sealed between the first and third panels. Furthermore, the first panel includes an outer opaque section and an inner transparent section through which the second panel is visible. In one embodiment, the electronic components for running the LCD panel are disposed between the first and third panels. In another embodiment, the electronic components are positioned in the rail and the rail includes a removable cover for accessing the electronic components. In an embodiment, one of the panels includes an electro-conductive film thereon that is generally clear, wherein when a voltage is applied across a portion of the film, the film becomes opaque. In an embodiment, the electronic components are powered by 24V DC. BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a perspective view of a series of refrigerated display cases that each include a door assembly with single glass unit having a center LCD panel;

FIG. 2 is a front elevational view of one of the single glass unit having a center LCD panel of FIG. 1 with a portion of the front outer pane cut away to show the electronic components;

FIG. 1 shows a series of refrigerated display case doors 100 that include a three-pane unit, single glass unit or package 10 with a transparent LCD panel 16 associated therewith. FIGS. 2-4 show the single glass unit 10 with front/outer pane 12, rear/inner pane 14 and center transparent LCD panel 16. It will be understood that in FIGS. 2-4 and 8, the outer perimeter or frame 102 of the door 100 is not shown. In a preferred embodiment, the panes are glass. However, any transparent material, such as plastic, can be used.

As shown in FIG. 3, in a preferred embodiment, the single glass unit 10 includes front and rear panes 12 and 14, LCD panel 16, electronic components 18, spacers 20 a, 20 b, 20 c,and insulation 22. In a preferred embodiment, the front and rear panes 12 and 14 include an opaque section 24 that obscures or hides components inside the unit 10. For example, by providing the opaque section 24 (preferably done by screen printing or some other type of coating) on selected areas of one or more of the panes 12 and/or 14, the spacers 20 a, 20 b, 20 cinsulation 22, electronic components 18 and other components can be housed inside the unit 10 (and the door 100) and hidden from view. Thermal insulation 22 may be added in certain areas to maintain the overall thermal performance of the door.

Each panel 12, 14 and 16, has a front and rear surface, For ease of description, these are described herein and depicted in FIG. 4 as surfaces 121, 122, 123, 124, 125 and 126. It will be appreciated by those skilled in the art that in use surface 121 faces the customer and surface 126 faces the interior space of the display case.

In a preferred embodiment, the opaque section 24 on the front and rear panes 12 and 14 (or dot matrix decorating, etc.) is placed on surfaces 122 and 125 to hide the components therein and the margin of the LCD panel, etc. However, this is not a limitation and the opaque section(s) can be placed on any desired surface.

It will be understood that the LCD panel may include a number of different layers or panes of glass/plexiglass or the like laminated to one another. Accordingly, as used herein, the LCD panel can be a single layer or multi-layer panel that includes an LCD screen for playing media. For example, the LCD screen may include a layer of glass adhered thereto to improve strength and reduce flex when the door is slammed. This can add strength to the LCD panel by essentially making it a double laminated panel. In a preferred embodiment, the LCD panel 16 has an aluminum rail therearound.

In a preferred embodiment, as shown in FIG. 3, unit 10 includes at least three different spacers 20 a, 20 band 20 c.Spacer 20 aspans the space between the front and rear panels 12 and 14, spacer 20 bspans the space between the front panel 12 and the LCD panel 16, and spacer 20 cspans the space between the rear panel 14 and the LCD panel 16, as is shown in FIG. 4. It will be understood that the spacers 20 a, 20 band 20 care adhered to a surface of the panel 12, 14 or 16. For example, spacer 20 ais adhered to the inner surfaces of front panel 12 and rear panel 14. In a preferred embodiment, the spacers 20 a, 20 band 20 care made of an elastomeric material. However, this is not a limitation on the present invention. The spacers can be made of other materials, such as a polymer, a metal such as aluminum, etc. The elastomeric material or spacers 20 band 20 csupports and suspends the LCD panel 16 inside the door and between the front and rear panels 12 and 14, thus helping prevent damage from shock and vibration when the door 100 closes. In another embodiment, the spacers 20 a, 20 band 20 ccan be formed as a unit, as shown in FIG. 8 and as shown in U.S. Pat. No. 6,148,563, the entirety of which is incorporated herein by reference. In this embodiment, the front and rear panels 12 and 14 are spaced from the center panel by spacers 20 band 20 c,but they are also connected by spacer 20 a.This essentially forms a single spacer with a detent in the middle for receiving the LCD panel 16.

When incorporating a single glass unit 10 with a transparent LCD panel 16, the door includes components 18 for operation of the LCD screen. As shown in FIGS. 2 and 4, in a preferred embodiment, the LCD panel 16 is smaller (length and width dimensions) than the outer panes 12 and 14. This provides space or a margin 25 around the perimeter of the LCD panel 16 for housing the components 18. For example, the unit 10 or door 100 can include circuit board(s) 26 (labeled A-D board in FIG. 2), wires or cables 28, a media player 30 (that includes a hard drive with memory and appropriate software) and associated connectors and such for providing media and/or power to the LCD panel 16. In another embodiment, the unit 10 can include one or more speakers 29, as shown in FIG. 7. In a preferred embodiment, components 18 are positioned within the margin 25 under the LCD panel 16. However, this is not a limitation on the present invention and the components 18 can be positioned as desired. See, for example, FIG. 7, where the components are positioned in the rail of the door, which is described more fully below.

As discussed above, in a preferred embodiment, unit 10 includes a media player 30 for controlling and playing media on the LCD panel 16. Data can be provided to the media player 30 via wires or cables or wirelessly, e.g., Wi-Fi, 802.11:x, etc., as desired (with the appropriate transmitter and/or receiver). In a preferred embodiment, the media player 30 includes a solid-state drive to prevent a spinning hard drive from failing when the door is slammed. However, this is not a limitation on the present invention and a spinning hard drive or other type of drive can also be used. Wireless (or wired) communications with the media player 30 can be used to deliver desired content to be played on the LCD panel 16, e.g, advertising content, nutritional content, special offers, etc. For example, the invention can implement IP addressable communications so an advertiser can remotely feed new data over the Internet. Furthermore, this allows remote monitoring of the health of the hard drive of the media player and associated electronic components.

In a preferred embodiment, the case into which the door 100 is mounted is pre-wired with low-voltage DC power supply, e.g. 12V, 24V, UL Class 2, etc. so that it accepts a transparent LCD door 100 with power through the hinge pin 31, or wired cords near the rotating hinge pin. However, this is not a limitation on the present invention. For example, a high-voltage option can also be implemented. As shown in FIG. 5, insulated electrical conductors and/or wired communications (for the media player 30 and associated components) can be directed through the hinge pin 31 (e.g., via TCP/IP-type Internet communications).

One feature of a preferred embodiment of the invention is to provide an electrical hinge pin 31, similar to the "582 patent hinge pin, but replacing the AC conductors of the "582 patent with low-voltage DC conductors and a data cable. The elimination of the high voltage AC conductors makes more space available in the hinge pin 31 for both the low-voltage DC antisweat heat and powering the electronics, and a data cable, e.g. Cat 5 with TCP/IP type communications. The low voltage conductors (e.g., 24V DC) can be used to power all electronic components, such as the components 18 for the LCD panel 16, heated glass, anti-sweat perimeter heating, etc. In another embodiment, the electrical hinge pin can be omitted and a regular hinge pin can be used. For example, in an outside mount embodiment of the door, the electronic components can be powered by (and data communicated therewith) a cord that does not run through the hinge pin. This type of door may be used, for example, on a self serve case at the end of a check out aisle in a store.

In a preferred embodiment, (and preferably in low-temp applications), an insulating gas, such as argon, xenon or other insulating gas can be used to fill the inner and/or outer cavities 32 between the LCD panel 16 and the front and rear panes 12 and 14, as shown in FIG. 4 (and other voids or cavities within the unit 10). In a preferred embodiment, the gas-filled inner cavities 32 are hermetically sealed (see seal 33 in FIG. 4) to keep from contaminating the transparent LCD panel 16 with dust, residue or outgassing from the outer insulated cavity containing insulation and electronics.

The thickness of the unit 10 can be different for different applications. However, in an exemplary embodiment, the overall thickness of the unit 10 is preferably about 0.125″, with the front and rear panes 12 and 14 being about 0.125″ thick and the center LCD pane 16 being about 0.125″ thick. These dimensions are not a limitation on the present invention.

In a preferred embodiment, any of the panes/panels 12, 14 or 16 can include an electro-conductive coating, such as a pyrolitic coating that is applied by spraying. It will be appreciated by those skilled in the art that other electro-conductive coatings can be used and can be adhered, applied, laminated or the like on a desired surface. For example, a chemical vapor deposition technique can be used. However, this is not a limitation on the present invention.

In a preferred embodiment, panes 12, 14 and 16 are preferably designed to maximize visible light transmission from inside the case to the customer, thereby improving the ability of customers to view display items. However, it is also desirable to minimize the transmission of non-visible light (i.e., ultraviolet and infrared light) through glass unit 10 from outside to inside the case in order to improve thermal performance and to protect items therein. Coolers are a type of refrigerated display case which operate at a temperature of approximately 38° F. Freezers are another type of refrigerated display case which operate below 0° F. When the glass unit 10 of such display cases comes into contact with ambient air, the relatively colder glass unit 10 can cause moisture in the air to condense on the surfaces of the glass unit. Thus, besides the use of the electro-conductive coating described above, it is desirable to use the non-visible wavelengths of light to heat the glass panels, thus reducing or preventing condensation. In a preferred embodiment, the panes 12, 14 and 16 can also include a UV inhibitor, which can help increase the shelf life of products inside. Also, panes 12, 14 and 16 may include low-emissivity heat-reflective coatings to improve overall thermal resistance and/or prevent external condensation. In an embodiment where reflection is an issue, an anti-reflective coating can be applied to any of the panes the glass unit 10.

In a preferred embodiment, touch screen technology 34, as shown in FIGS. 1 and 6, can be used. Exemplary touch screen technology is disclosed in U.S. Patent Publication Nos. 2009/0146945 and 2007/0216657, the entireties of which are incorporated by reference herein. In this embodiment, a user can touch the front of the outer panel 12 and access information as desired. In various embodiments, the entire outer panel 12 can incorporate touch screen technology or only various portions of the outer panel 12 can include touch screen technology. For example, the user can access nutritional information about the contents of the case or the user can access information about the layout of the store.

In a preferred embodiment, the unit 10 includes motion sensor technology, such as a visual recognition camera 36, as shown in FIG. 6. In this embodiment, the media player 30 only plays content on the LCD panel 16, when a person walks by or in front of the unit 10. In an exemplary embodiment, the unit 10 can include software that allows the camera 36, and/or the components thereof, to recognize if a man or a woman is standing in front of the door 100. Therefore, the advertisement or other media played on the LCD panel 16 can be tailored to the specific gender of the person standing in front of the door 100.

In another preferred embodiment, two or more smaller screens can be combined in a matrix to increase the visible display area. For example a 46″ 16:9 standard TV size in a 30″×67″ door leaves a large opaque margin top and bottom. Two smaller adjacent panels would leave more space for visible transmittance. Another way to increase the visible area is to cut down the long side of a larger 16:9 LCD panel such that it better fits the typical 67″ or 75″ vertical height but would otherwise exceed the standard 30″ width.

Furthermore, the LCD panel does not have to be the center panel. In other embodiments, the LCD panel can be the inside or outside panel. For example, a transparent LCD screen can be adhered or laminated to the outside panel or the inside panel of a triple pane refrigerator door. In another embodiment, the unit 10 can include more than three panels or panes. For example, the LCD panel 16 can be inserted between the first and second or second and third panels in a triple pane refrigerator door.

In a preferred embodiment, a separate pocket is created in the margin of the door outside the hermetic seal of the insulated glass, that would allow access to the media player and related electronic components 18 for service or upgrade. This can be implemented by using an “offset” insulated glass package/unit (e.g. pane number three is smaller than pane number one) to create the pocket to contain the media player or other electronics to allow service. However, the glass package/unit does not have to be offset. In another embodiment, as shown in FIG. 7, the pocket 38 is created or defined in the hollow area made by the rail 106. As shown, the rail 106 can include a cover 40 that is removably attached to the rail 106 by threaded fasteners or the like. The cover 40 can be removed to allow access to the pocket 38 and the electronic components 18 therein, thus allowing repair, upgrade, replacement, etc. In FIG. 7, the pocket 38, cover 40 and components 18 are shown in the top rail 106 of the door 100. However, the pocket 38, cover 40 and components 18 (such as speaker 29) can be mounted in any rail or portion of the frame. In another embodiment, the electronic components for running the LCD panel can be mounted in the display case or refrigerator.

In another preferred embodiment, the unit 10 includes a switchable film or glass 42 disposed or laminated on at least one of the surfaces of the front or rear panels 12 and/or 14, as shown in FIGS. 6 and 8. In a preferred embodiment, the film is disposed on surface five, which is the front surface of the rear panel 14. The panel with the switchable film 42 can be formed by laminating a liquid crystal switchable film thereon or the film can be directly mounted on the panel with a double sided tape, optical glue or the like. In use, a voltage is selectively applied to the film to make it either clear or opaque as desired. In a preferred embodiment, if a voltage is applied to the film, it goes clear and if no voltage is applied it is opaque or frosted. Therefore, in use, if no voltage is applied, images on the clear LCD panel look like a regular television, which helps accentuate the images on the transparent LCD panel and eliminate the distracting contrast of the product in the display case. Then when a voltage is applied, the film goes clear and the product in the case is easier to see. In another embodiment, the film 42 is disposed on the front or center panels. In another embodiment, the film 42 is disposed on another panel, such as a fourth panel. In another embodiment, the single glass unit includes only two panels, one of which is the LCD panel and the other includes the switchable film 42. This type of unit can be used in non-door applications, such as in department store windows, etc. where the window is desirable to be transparent at times and opaque at other times to better see the media on the LCD panel. As will be appreciated by those skilled in the art, appropriate wiring and the like can be associated with the film 42 to supply the voltage. In a preferred embodiment, switchable film 42 is backlit with the display case lighting.

In an embodiment, the door 100 can include a light guide plate (made of glass, plexiglass or the like) that helps illuminate (preferably via LED lighting) the images on the LCD panel. Other types of lighting for LCD panel are also within the scope of the invention.

An organic light-emitting diode (OLED or organic LED), also known as organic electroluminescent (organic EL) diode,light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. This organic layer is situated between two electrodes; typically, at least one of these electrodes is transparent. OLEDs are used to create digital displays in devices such as television screens, computer monitors, and portable systems such as smartphones and handheld game consoles. A major area of research is the development of white OLED devices for use in solid-state lighting applications.

An OLED display works without a backlight because it emits its own visible light. Thus, it can display deep black levels and can be thinner and lighter than a liquid crystal display (LCD). In low ambient light conditions (such as a dark room), an OLED screen can achieve a higher contrast ratio than an LCD, regardless of whether the LCD uses cold cathode fluorescent lamps or an LED backlight. OLED displays are made in the same way as LCDs, but after TFT (for active matrix displays), addressable grid (for passive matrix displays) or indium-tin oxide (ITO) segment (for segment displays) formation, the display is coated with hole injection, transport and blocking layers, as well with electroluminescent material after the first 2 layers, after which ITO or metal may be applied again as a cathode and later the entire stack of materials is encapsulated. The TFT layer, addressable grid or ITO segments serve as or are connected to the anode, which may be made of ITO or metal.transparent displays being used in smartphones with optical fingerprint scanners and flexible displays being used in foldable smartphones.

On 5 December 2017, JOLED, the successor of Sony and Panasonic"s printable OLED business units, began the world"s first commercial shipment of inkjet-printed OLED panels.

Indium tin oxide (ITO) is commonly used as the anode material. It is transparent to visible light and has a high work function which promotes injection of holes into the HOMO level of the organic layer. A second conductive (injection) layer is typically added, which may consist of PEDOT:PSS,barium and calcium are often used for the cathode as they have low work functions which promote injection of electrons into the LUMO of the organic layer.aluminium to avoid degradation. Two secondary benefits of the aluminum capping layer include robustness to electrical contacts and the back reflection of emitted light out to the transparent ITO layer.

The bottom-emission organic light-emitting diode (BE-OLED) is the architecture that was used in the early-stage AMOLED displays. It had a transparent anode fabricated on a glass substrate, and a shiny reflective cathode. Light is emitted from the transparent anode direction. To reflect all the light towards the anode direction, a relatively thick metal cathode such as aluminum is used. For the anode, high-transparency indium tin oxide (ITO) was a typical choice to emit as much light as possible.thin film transistor (TFT) substrate, and the area from which light can be extracted is limited and the light emission efficiency is reduced.

An alternative configuration is to switch the mode of emission. A reflective anode, and a transparent (or more often semi-transparent) cathode are used so that the light emits from the cathode side, and this configuration is called top-emission OLED (TE-OLED). Unlike BEOLEDs where the anode is made of transparent conductive ITO, this time the cathode needs to be transparent, and the ITO material is not an ideal choice for the cathode because of a damage issue due to the sputtering process.transmittance and high conductivity.

Color filters can also be implemented into bottom- and top-emission OLEDs. By adding the corresponding RGB color filters after the semi-transparent cathode, even purer wavelengths of light can be obtained. The use of a microcavity in top-emission OLEDs with color filters also contributes to an increase in the contrast ratio by reducing the reflection of incident ambient light.

Transparent OLEDs use transparent or semi-transparent contacts on both sides of the device to create displays that can be made to be both top and bottom emitting (transparent). TOLEDs can greatly improve contrast, making it much easier to view displays in bright sunlight.Head-up displays, smart windows or augmented reality applications.

For a high resolution display like a TV, a thin-film transistor (TFT) backplane is necessary to drive the pixels correctly. As of 2019, low-temperature polycrystalline silicon (LTPS)– TFT is widely used for commercial AMOLED displays. LTPS-TFT has variation of the performance in a display, so various compensation circuits have been reported.excimer laser used for LTPS, the AMOLED size was limited. To cope with the hurdle related to the panel size, amorphous-silicon/microcrystalline-silicon backplanes have been reported with large display prototype demonstrations.indium gallium zinc oxide (IGZO) backplane can also be used.

OLEDs can be printed onto any suitable substrate by an inkjet printer or even by screen printing,plasma displays. However, fabrication of the OLED substrate as of 2018 is costlier than that for TFT LCDs.registration — lining up the different printed layers to the required degree of accuracy.

OLEDs enable a greater contrast ratio and wider viewing angle compared to LCDs, because OLED pixels emit light directly. This also provides a deeper black level, since a black OLED display emits no light. Furthermore, OLED pixel colors appear correct and unshifted, even as the viewing angle approaches 90° from the normal.

LCDs filter the light emitted from a backlight, allowing a small fraction of light through. Thus, they cannot show true black. However, an inactive OLED element does not produce light or consume power, allowing true blacks.nm. The refractive value and the matching of the optical IMLs property, including the device structure parameters, also enhance the emission intensity at these thicknesses.

OLEDs also have a much faster response time than an LCD. Using response time compensation technologies, the fastest modern LCDs can reach response times as low as 1ms for their fastest color transition, and are capable of refresh frequencies as high as 240Hz. According to LG, OLED response times are up to 1,000 times faster than LCD,μs (0.01ms), which could theoretically accommodate refresh frequencies approaching 100kHz (100,000Hz). Due to their extremely fast response time, OLED displays can also be easily designed to be strobed, creating an effect similar to CRT flicker in order to avoid the sample-and-hold behavior seen on both LCDs and some OLED displays, which creates the perception of motion blur.

The biggest technical problem for OLEDs is the limited lifetime of the organic materials. One 2008 technical report on an OLED TV panel found that after 1,000hours, the blue luminance degraded by 12%, the red by 7% and the green by 8%.hours to half original brightness (five years at eight hours per day) when used for flat-panel displays. This is lower than the typical lifetime of LCD, LED or PDP technology; each rated for about 25,000–40,000hours to half brightness, depending on manufacturer and model. One major challenge for OLED displays is the formation of dark spots due to the ingress of oxygen and moisture, which degrades the organic material over time whether or not the display is powered.

However, some manufacturers" displays aim to increase the lifespan of OLED displays, pushing their expected life past that of LCD displays by improving light outcoupling, thus achieving the same brightness at a lower drive current.cd/m2 of luminance for over 198,000hours for green OLEDs and 62,000hours for blue OLEDs.hours for red, 1,450,000hours for yellow and 400,000hours for green at an initial luminance of 1,000cd/m2.

Degradation occurs three orders of magnitude faster when exposed to moisture than when exposed to oxygen. Encapsulation can be performed by applying an epoxy adhesive with dessicant,Atomic Layer Deposition (ALD). The encapsulation process is carried out under a nitrogen environment, using UV-curable LOCA glue and the electroluminescent and electrode material deposition processes are carried out under a high vacuum. The encapsulation and material deposition processes are carried out by a single machine, after the Thin-film transistors have been applied. The transistors are applied in a process that is the same for LCDs. The electroluminescent materials can also be applied using inkjet printing.

Improvements to the efficiency and lifetime of blue OLEDs is vital to the success of OLEDs as replacements for LCD technology. Considerable research has been invested in developing blue OLEDs with high external quantum efficiency, as well as a deeper blue color.

As an emissive display technology, OLEDs rely completely upon converting electricity to light, unlike most LCDs which are to some extent reflective. E-paper leads the way in efficiency with ~ 33% ambient light reflectivity, enabling the display to be used without any internal light source. The metallic cathode in an OLED acts as a mirror, with reflectance approaching 80%, leading to poor readability in bright ambient light such as outdoors. However, with the proper application of a circular polarizer and antireflective coatings, the diffuse reflectance can be reduced to less than 0.1%. With 10,000 fc incident illumination (typical test condition for simulating outdoor illumination), that yields an approximate photopic contrast of 5:1. Advances in OLED technologies, however, enable OLEDs to become actually better than LCDs in bright sunlight. The AMOLED display in the Galaxy S5, for example, was found to outperform all LCD displays on the market in terms of power usage, brightness and reflectance.

While an OLED will consume around 40% of the power of an LCD displaying an image that is primarily black, for the majority of images it will consume 60–80% of the power of an LCD. Ho
