I saw a really cool video of a PC case called "Snowblind", that had a transparent LCD Screen as a side panel. I was amazed over how cool it was. The only problem was that it was really expensive. Therefore, I tried making my own! In this instructables I will go through how I made it, and how you could make your own. The best of all, since it was made from an old monitor that was thrown away, it was basically free! I just added some LED strips on the inside of the case to get better contrast on the screen. You could probably re-use the monitors backlight, but it"s safer and easier to just get some cheap LED strips.

First, remove the frame of the panel. It is fixed with clips, so just bend the frame a little and lift the frame up. Next, separate the front LCD from the backlight. For the next step, you will have to be careful. This step involves removing the anti glare film. It is glued to the panel, and therefore it"s easy to break the LCD when trying to remove it.

Then you are done modding the LCD! Now, you can hook it up to the panel and test it. Just be careful with the ribbon cables going from the LCD PCB to the panel.

The side panel of this case fits the LCD perfectly. Just line it up to the side facing the back, and to the top, and use some tape to tape it to the glass. Then, use some vinyl on the outside where the LCD is not covering the glass.

It"s really important to have lots of lights inside the case, to make it easier to see the LCD. Therefore, try to fill the case with even more LED strips.

Now you can carefully mount the side panel back on the computer. You might have to drill a new hole for the thumb screw in the back to make it fit properly.

Hey I have a little question, I also have a Dell 1905FP, but I think it"s an older model because I don"t have a ribbon cable but a normal cable with a plug. My problem is that I have peeled off one film but it still looks like there is a second film on the back because it is still a little blurry. But I"m afraid that if I try to pull them off, my LCD display will break. Maybe you have an idea. Thanks in advance

Great tutorial and video! I"m trying my hand at replicating your process and I even got my hands on the exact monitor. I have reached the point where I"ve disassembled the panel and controllers, and discharged the capacitors from the PSU, but I am a little stuck at this point because I don"t know how to wire up the molex header. I watched your video and saw that you had two wires soldered to the power connector. Which connectors are they and where do they go on the molex cable? Thank you!

Terrific job! May I ask why you would need to remove the front polarizer? If my understanding is correct, both the front and back polarizers are needed in order for the LCD to work properly (i.e., the light gets polarized by the back polarizer first, and then passes through the front polarizer)? You comments will be appreciated!

I think you should have more pics and info about the re- mounting the LCD. After all if you don"t do it right all that work is for nothing. While I understand your wiring diagram, I think that it should be explained and a larger part of this Instructible...for example to get white lite your are powering all 3 lanes (red,green,blue) on the RGB tape.

Hello, Wonderfull project, I have the same case and I would love to do it (if I have time and the screen to the right size). Just a question, can you put a photo of the cable connection to see if it"s easy to open the case ? One little suggestion, instead of connecting the panel to the graphic card (which mean to run a cable outside, why don"t you use a USB to VGA or DVI converter (like this https://www.amazon.fr/Adaptateur-convertisseur-adaptateur-Affichage-multi-écrans/dp/B079L81FRD/ref=asc_df_B079L81FRD/?tag=googshopfr-21&linkCode=df0&hvadid=227894524041&hvpos=&hvnetw=g&hvrand=17927658121409960098&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9055710&hvtargid=pla-442905712462&psc=1) ?

Transparent LCD’s provide an innovative display solution opening up new ways for brands to promote their products and services. Examples include retail stores looking to advertise a new fashion clothing or accessory, museums securely housing a precious artifact with information displayed on screen or brands looking to launch a new product at a live event or show. The opportunities are endless!

Our Transparent LCD Displays include a Grade A LCD panel with metal bezel protecting the edges / electronics and a media board supporting HDMI or VGA inputs from your PC, Laptop or Media Player.

Transparent screen technology offers intriguing ways to deliver visual information to your audience, being used to reveal or conceal products, objects or artefacts behind the screen.

The combination of HD LCD technology (4K on our 65″, 86″, 98″ version) with a transparent screen substrate opens up creative avenues that were previously closed with traditional LCD displays. Solid black pixels on a transparent background can be used in intriguing ways to hide (and gradually reveal) whatever is behind the screen.

Our Transparent LCD monitors are designed for integration into the customers own furniture housing or display case while our Transparent LCD showcases offer a complete solution including the display, housing and backlight with white or black options available on request. We can also offer custom freestanding options for POP / POS displays. Transparent LCD’s are predominantly fully housed however we’ve recently developed an innovative housing method using a high brightness LED panel which allows the display case sides to remain transparent for improved visibly into the display case.

Using their original design as a starting point, we worked closely with the team at Nike to adapt to the mechanical aspects of the design, the result was a sleek and minimalist set of nine Transparent LCD Display Screens, custom built to suit the applications requirements, bringing Nike’s original concept ideas to life.

Transparent LCD’s comprise of an LCD panel without the backlight with white pixels appearing as transparent. In order to display an image, the Transparent LCD needs to be integrated into a housing with a high bright LED backlight.

We can also offer more complete solutions like our Transparent LCD Showcase that comes fully contained and ready to use with a powerful backlighting system to guarantee the best picture quality.

Yes in order to display an image Transparent LCD’s need to have a strong backlight. Notoriously Transparent LCD’s have also needed some form of housing to achieve optimum image quality, however, Nike’s House of Innovation paired our Transparent LCD’s with powerful, oversized backlights that allowed the screens to be mounted with no surround but still producing a high-quality image.

Transparent LCD’s are arguably the most popular transparent screens but are hindered by their need for a backlight to operate. For applications looking for a similar effect without the backlighting, Transparent OLEDs require no housing or surround but are only currently available in a 55″ screen size with HD quality. For larger transparent screen applications, Transparent LED’s are recommended with external and internal solutions usually installed to glass facades for the impact of an led screen without compromising the view from inside the building.

We also offer transparent projection technologies including our Clearview Rear Projection Film featured in Guardians of the Galaxy as well as at the 83rd Oscars celebration and MTV EMA awards.

Transparent LCD’s are a great way to combine physical and digital displays in one central place making them a popular choice for museums and exhibitions. Our transparent screens can also be integrated into display furniture and appliances & vending machines like freezer doors for supermarkets. Other uses include POS displays, store window displays, trade shows and product launches.

Quite a feat of technology, transparent displays become more widely available and affordable each year. If you are unsure whether to invest in them, we point out the advantages and usages they offer to outdoor advertising below to shed more light on the continually growing potential of transparent displays which might sway you in their direction!

Not all transparent displays are the same—that’s the first thing to know. It’s important to establish which variant of transparent displays suits your needs best. Now, if you’re looking to find out what the best transparent display type is and be done with it, we’re sorry to disappoint you. Some are better than others for certain circumstances. We start off by covering two of the most important types.

Just like standard LCD displays, transparent LCD displays need a light in the back of the screen to produce a visible image. The pixels on an LCD screen do not emit light but instead rely on the backlight to provide it, then block out the output of the blacklight to display appropriate colors. This makes them very good to use in well-illuminated areas, especially outdoors.

When it comes to their weaknesses, as LCD displays need the backlight to produce images, they’re not the best at producing a pure black color. Furthermore, their brightness is limited and the viewing angle can impact the vibrancy of colors and picture quality.

While LCD displays block light, each pixel in any OLED display emits its own light. Not requiring backlight illumination makes OLED displays particularly powerful in darker areas and indoors. We find a good example for this in LGs transparent OLEDs used assubway windows. There are several other benefits unique to OLEDs such as colors staying vibrant from all viewing angles. The absence of backlights physically installed in the display allows for thinner and lighter displays.

Initially you might think a transparent display of any kind is limited in interactive features, but know that interactivity is not at all a challenge. It is in fact highly recommended you implement interactivity with transparent displays if suiting your needs. Even though a transparent display is not brand new technology, it’s still very likely to engage people to interact.

A good example for the potential of interactivity came during theCOVID-19 pandemic. With clear physical barriers becoming more prominent, it offers more opportunities for transparent displays. Even if we take interactivity out of the equation, a transparent display can fill in that awkward barrier that divides us and make it appear as more of a luxurious convenience rather than yet another reminder of the pandemic we all know quite well by now.

Even though they’ve been available for a little while, transparent displays haven’t reached their peak diffusion just yet. The beauty of this for anyone getting them now is that they still draw attention and excitement to them.

Transparent LCD displays are great for featuring products on display behind, inviting the viewer to take a closer look. For example, place them in the store front to highlight specific features for certain products.

When investing in larger transparent displays, keep this in mind. If your transparent displays are going to be mid-air, they’ll naturally need additional support. In this case, perhaps it would be better to avoid hanging displays, or find a better location where very few people will be able to see the display from the back.

Images in png format are ideal for transparency. Digital signage software makes it a breeze to combine a variety of images and videos with transparent backgrounds by overlapping them. Naturally, you can use this feature even if you don’t have a transparent display. Use the transparency attribute tocombine different visual components seamlessly. Here’s an example of how you could overlay a logo over the principal content in your campaigns without much trouble.

This content creation characteristic will come in handy for transparent displays and is only one of the many OnSign TV offers. You can check out all of them right now and see which ones suit you best after you sign up forOnSign TV for free!

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.

Why do monitors and TVs get image burn? Why can"t manufacturers prevent LCDs and plasma screens from a burnt image imprint? Moreover, what can you do to fix an image burn?

LCD and LED do not work in the same way as CRTs, either. LCD and LED screens use backlit liquid crystals to display colors. Although manufacturers market screens using LED and LCD, an LED screen is still a type of LCD. The white backlight filters through the liquid crystals, which extract particular colors per pixel.

LCD and LED displays don"t suffer from the same type of image burn as CRTs and plasma screens. They"re not completely clear, though. LCD and LED screens suffer from image persistence. Read on to find out more about image persistence.

Before you can fix screen burn-in, take a second to understand why these images burn in the first place. LCDs and LEDs don"t suffer from burn-in as seriously as plasma screens. But static images can leave an imprint on both display types if left alone for too long. So, why does image burn happen?

LCD and LED screens can also experience image burn, though the image burn process can take longer to develop into a permanent issue. In addition, LCD and LED screens suffer from another issue, known as image retention (also known as image persistence or an LCD shadow).

Image retention is a temporary issue that you are more likely to notice before it becomes a permanent issue. However, proper image burn can still affect LCD, LED, and OLED screens.

Image burn-in fixes exist for LCD and plasma screens. How effective an image burn-in fix is depends on the screen damage. Depending on the length and severity of the image burn, some displays may have permanent damage.

The best fix for screen burn is to prevent it in the first place. Okay, that isn"t super useful if your screen is already experiencing image burn. However, you should always try not to leave your screen on a still image for too long. The time it takes for an image to burn-in varies from screen to screen, between manufacturers, sizes, and panel type.

If your plasma or LCD screen already has image burn-in, you can try turning on white static for 12 to 24 hours. The constant moving of white-and-black across your screen in random patterns can help remove the ghost image from your screen.

Pixel-shift constantly slightly adjusts the image on your screen, which varies the pixel usage to counteract image burn. You might have to enable a pixel or screen shift option in your screen settings. Pixel-shift is a handy feature for LED and OLED screens that cannot recover from image burn and should help counteract an LCD shadow.

While the Deluxe version uses advanced algorithms to repair burned screens and prolong plasma and LCD longevity, the official site is no longer up and running, and there is no way to download the full version officially.

Transparent Organic Light Emitting Diode (TOLED) is a type of LED that, as you can guess, has a transparent screen. It builds on the now common OLED screens found in smartphones and TVs, but with a transparent display, offers up some new possibilities for Arduino screens.

Take for example this brilliant project that makes use of TOLED displays. By stacking 10 transparent OLED screens in parallel, creator Sean Hodgins has converted a handful of 2D screens into a solid-state volumetric display. This kind of display creates an image that has 3-dimensional depth, taking us one step closer to the neon, holographic screens we imagine in the future.

The liquid crystal display (LCD) is the most common display to find in DIY projects and home appliances alike. This is no surprise as they are simple to operate, low-powered, and incredibly cheap.

The screens are capable of a large variety of preset characters which cover most use cases in a variety of languages. You can control your LCD using the Liquid Crystal Library provided by Arduino. The display() and noDisplay() methods write to the LCD, as shown in the official tutorial on the Arduino website.

These tiny LCD screens are monochrome and have a screen size of 84 x 48 pixels, but don"t let that fool you. Coming in at around $2 on AliExpress, these displays are incredibly cheap and usually come with a backlight as standard.

Thin-film-transistor liquid-crystal displays (TFT LCDs) are in many ways another step up in quality when it comes to options for adding a screen to your Arduino. Available with or without touchscreen functionality, they also add the ability to load bitmap files from an on-board microSD card slot.

Arduino have an official guide for setting up their non-touchscreen TFT LCD screen. For a video tutorial teaching you the basics of setting up the touchscreen version, YouTuber educ8s.tv has you covered:

This document describes techniques and apparatuses for implementing a transparent display device. A transparent display device includes a transparent or translucent screen to render images on the screen, and to render virtual objects that appear to be in a three-dimensional (3D) space behind the screen.

FIG. 1 is an illustration of an example environment 100 in which a transparent display device can be implemented. Environment 100 includes a transparent display device 102, which is illustrated, by way of example and not limitation, as one of a smart phone 104, a laptop computer 106, a television device 108, a desktop computer 110, or a tablet computer 112.

Transparent display device 102 includes processor(s) 114 and computer-readable media 116, which includes memory media 118 and storage media 120. Applications and/or an operating system (not shown) embodied as computer-readable instructions on computer-readable media 116 can be executed by processor(s) 114 to provide some or all of the functionalities described herein. Computer-readable media also includes a controller 122. How controller 122 is implemented and used varies, and is described in further detail below.

Transparent display device 102 also includes a transparent screen 124 that is configured to render images on the screen, and to render virtual objects that appear to be in a three-dimensional (3D) space behind the screen. While referred to as a transparent screen herein, transparent screen 124 can be implemented as either a transparent screen or as a semi-transparent or translucent screen. Transparent screen 124 can be implemented to render two-dimensional (2D) images and/or 3D images. For example, in some embodiments transparent screen 124 can render 2D images that are typically displayed on a 2D screen, such as a word-processing document, a PDF document, 2D pictures, or 2D video, to name just a few. Alternately or additionally, transparent screen 124 can render 3D images that can be viewed with or without eye glasses. For example, in some cases transparent screen 124 can be implemented to render 3D images using an optic such as a wedge that can be viewed by a user without the use of eye glasses. In other cases, transparent screen 124 can render 3D images that can be viewed by a user wearing eye glasses, such as shutter glasses, polarized glasses, or lenticular glassless displays, to name just a few.

As described in more detail below, transparent display device 102 can be controlled to transition between rendering the 2D images and/or 3D images on the transparent screen and rendering the virtual objects that appear to be in the 3D space behind the transparent screen. As discussed in more detail below, the images displayed on the transparent screen may be opaque, or partially opaque, to cover the virtual objects, but can be controlled to slide away to reveal the virtual objects displayed behind transparent screen 124.

In various embodiments, transparent screen 124 may be configured as a 2D or 3D flat-panel electronic display, such as a high-resolution liquid crystal display (LCD). Transparent screen 124 can be physically coupled to transparent display device 102 or implemented separate from transparent display device 102. For example, transparent screen 124 is physically coupled to laptop computer 106 but is implemented separate from desktop computer 110.

FIG. 2 illustrates a detailed example 200 of transparent display device 102 in accordance with one embodiment. In this example, transparent screen 124 uses a grid 202 to render virtual objects 204 that appear to a user as if the virtual objects are rendered in a 3D space 206 behind transparent screen 124. It is to be appreciated that grid 202 may not be viewable by the user, but is used by transparent display device 102 to render the virtual objects so that they appear to be positioned in the 3D space behind transparent screen 124. In this example, virtual objects 204 are depicted as windows 208 and 210. Windows 208 and 210 can each represent a page associated with an application, such a web browser page, a word-processing document, or a PDF file. It is to be noted, however, that transparent screen 124 can render any type of virtual object in 3D space 206.

By rendering virtual objects 204 that appear to be in 3D space 206, transparent screen 124 enables the user to manipulate virtual objects 204 using one or both of the user"s hands. It is to be noted that transparent screen 124 is transparent and thus enables the user to see the user"s actual hands (as opposed to a virtual rendering of the user"s hands) as the user manipulates virtual objects 204. Thus, transparent display device 102 leverages the user"s spatial understanding and kinesthetic memory to access and manipulate virtual objects 204 in 3D space 206.

Transparent display device 102 also includes a hand tracker 126, which is configured to sense movement of the user"s hands, such as gestures, to interact with one or more of virtual objects 204 in 3D space 206 behind transparent screen 124, and to generate 3D-input based on the movement. In an embodiment, hand tracker 126 is implemented as a depth camera that senses a 3D position, movement, and/or pose of each of the user"s hands. As discussed in more detail below, controller 122 is configured to receive the 3D-input from hand tracker 126, and to modify the rendering of the 2D or 3D images on transparent screen 124 (not illustrated in FIG. 2) or virtual objects 204 in 3D space 206, based on the 3D-input.

In some embodiments, transparent display device 102 also includes an input panel 128 that is positioned behind transparent screen 124 and is configured to receive 2D-input, such as touch-input and/or key-input, from the user. In this example, as opposed to the conventional design of a laptop where the laptop screen is attached to the trailing edge (far from the user) of the keyboard panel, transparent screen 124 is coupled to a near-edge (edge closer to the user) of input panel 128. Input panel 128 may include any combination of a keyboard configured to receive key-input or a mouse, track pad, touch pad, or other 2D sensing device configured to receive touch-input. By being positioned behind transparent screen 124, input panel 128 enables the user to reach behind the transparent screen to use the input panel.

It is to be noted that because transparent screen 124 is transparent or translucent, the user may be able to see input panel 128 as the key-input or touch-input is entered. For example, when input panel 128 includes a keyboard, the user may be able to see both the keys of the keyboard and the user"s fingers through the transparent screen as the user types on the keyboard. Further, the position of input panel 128 behind transparent screen 124 enables the user to easily transition between using input panel 128 (e.g., for typing) to manipulating virtual objects 204 in 3D space 206. For example, if the user is typing on the keyboard of input panel 128, the user can simply raise one or both of the user"s hands in order to manipulate or interact with virtual objects 204.

FIG. 3 illustrates a detailed example 300 of a side view of the transparent display device illustrated in FIG. 2. In this example, transparent screen 124 is coupled to input panel 128 via a foldable hinge 302. Foldable hinge 302 enables transparent screen 124 to fold on top of input panel 128 to close transparent display device 102. Foldable hinge 302, in this example, is attached to the middle of both transparent screen 124 and input panel 128, which enables the user to comfortably place the user"s hands behind the transparent screen to use input panel 128.

While examples 200 and 300 illustrate transparent screen 124 as being physically attached to input panel 128, alternately input panel 128 may be positioned behind transparent screen 124 without being physically connected to the transparent screen. For example, transparent screen 124 may be implemented as a desktop monitor, and input panel 128 may be implemented as a keyboard and/or mouse that can be placed behind the desktop monitor.

In some embodiments, transparent display device 102 also includes a head tracker 130 that is configured to track a position of the user"s head or eyes relative to transparent screen 124. Controller 122 is configured to render, or modify the rendering of, virtual objects 204 based on the position of the user"s head or eyes so that the virtual objects appear to be in 3D space 206. Head tracker 130 can be implemented as a 3D camera or as an array of cameras. In various embodiments, both hand tracker 126 and head tracker 130 may be implemented as short-range depth cameras. In example 200, hand tracker 126 and head tracker 130 can be mounted to transparent screen 124, making transparent display device 102 truly a mobile device. Thus, controller 122 controls transparent display device 102 to render virtual objects 204 on transparent screen 124 that are updated in real time based on the user"s eye or head position, such that the user perceives that the virtual objects are displayed behind the transparent screen at a programmed set position.

FIG. 4 aillustrates a detailed example 400 of transparent display device 102 in accordance with one embodiment. In this example, transparent display device 102 renders a 2D or 3D image 402 on the surface of transparent screen 124. Image 402 may be any type of 2D image that can be displayed on a conventional 2D screen, or 3D image that can be displayed on a 3D screen. In this example, image 402 is a picture of a pair of dice. Note, however, that transparent screen 124 may display image 402 as a web browser window, a word-processing document, a picture, or a PDF file, to name just a few examples. The user can interact with image 402 using input panel 128. For example, the user can type on the keyboard of input panel 128 to write an email message, or use a track pad or mouse of the input panel to modify the size of image 402. Transparent display device 102 receives the 2D-input from the user via input panel 128, and controller 122 controls the transparent display device to modify the rendering of image 402 on the transparent screen based on the 2D-input.

In various embodiments, transparent display device 102 employs a “sliding door” technique when the user raises one or both of the user"s hands off of input panel 128 to reach into the 3D space behind transparent screen 124. Consider for example that in FIG. 4 bthe user raises one of the user"s hands off of input panel 128 to reach into 3D space 206. Hand tracker 126 senses this movement, and generates 3D-input that is received by controller 122. Controller 122 then controls transparent screen 124 to slide the rendering of image 402 to reveal one or more virtual objects that appear to be in 3D space 206 behind transparent screen 124. In this example, the rendering of image 402 is controlled to slide down transparent screen 124. Alternately, however, the rendering of image 402 can be controlled to slide up transparent screen 124 or to slide across (e.g., slide left across or slide right across) transparent screen 124. In some embodiments, image 402 can also or instead be controlled to fade, dissolve, or transition in any other way to reveal the virtual objects in 3D space 206.

After the rendering of the image on the screen slides to reveal the virtual objects, the user can interact with the virtual objects using one or both of the user"s hands. In an embodiment, when the user lowers the user"s hand to go back to entering input using input panel 128, hand tracker 126 senses the movement of the user"s hand to reach towards the input panel and generates 3D-input that is received by controller 122. Controller 122 then controls transparent screen 124 to slide the rendering of image 402 to cover the one or more virtual objects (e.g., slide back up, back down, back left, or back right). It is to be appreciated, therefore, that the sliding door technique enables the user to easily transition between entering 2D-input via input panel 128 and entering 3D-input using the user"s hands in 3D space 206.

Transparent display device 102 enables the user to interact with virtual objects that appear to be in the 3D space behind transparent screen 124 in a variety of different ways. In an embodiment, transparent display device 102 employs a “virtual cabinet” technique to cause transparent screen 124 to render multiple windows stacked in one or more 3D volumes that appear to be in 3D space 206. For example, FIG. 5 aillustrates another detailed example 500 of transparent display device 102 in accordance with one embodiment. In this example, transparent screen 124 renders multiple windows stacked in 3D volumes 502 and 504 that appear to be in 3D space 206. Each of the windows stacked in 3D volumes 502 and 504 can represent a page associated with an application, such a web browser page, a word-processing document, or a PDF file.

Transparent display device 102 enables the user to interact with 3D volumes 502 and 504 in 3D space 206 by positioning one or both of the user"s hands near the 3D volumes in 3D space 206. Hand tracker 126 is configured to sense movement of the user"s hand behind the transparent screen to select one of 3D volumes 502 or 504, and to generate 3D-input based on the movement. Responsive to receiving the 3D-input from hand tracker 126, controller 122 controls transparent display device 102 to render the selected 3D volume as open on transparent screen 124 to enable the user to interact with the multiple windows stacked in the selected 3D volume.

It is to be noted that rendering the 3D volume as open enables the user to more easily view the multiple windows in the selected 3D volume. For example, in FIG. 5 a, 3D volumes 502 and 504 are rendered as closed making it difficult for the user to see, or select, each individual window in 3D volumes 502 and 504. In FIG. 5 b, if the user moves the user"s hand to select 3D volume 504, the movement of the user"s hand is sensed by hand tracker 126 which generates 3D-input that is received by controller 122. Controller 122 then controls transparent screen 124 to modify the rendering of 3D volume 504 to render 3D volume 504 as open. For example, as illustrated in FIG. 5 b, the windows in 3D volume 504 are open, or spread out, as compared to the windows in 3D volume 502. Opening the 3D volume enables the user to more easily see, and thus more easily interact with, each of the windows in 3D volume 504.

Transparent display device 102 enables the user to interact with the multiple windows in open 3D volume 504 by positioning one or both of the user"s hands near the multiple windows in 3D space 206. For example, in FIG. 5 cif the user moves the user"s hand to one of the multiple windows 506 in 3D volume 504, the movement of the user"s hand is sensed by hand tracker 126 which generates 3D-input. Controller 122 receives the 3D-input and controls transparent screen 124 to render selected window 506 as selected. For example, in FIG. 5 ccontroller 122 controls transparent display device 102 to render window 506 as selected by causing window 506 to “pop up” out of 3D volume 504. Popping window 506 out of 3D volume 504 enables the user to see more information regarding window 506. The user can then select window 506, such as by pinching the window, to display the window as a 2D image on transparent screen 124.

In various embodiments, transparent display device 102 is configured to provide feedback on transparent screen 124 based on the location of the user"s hands in 3D space 206. In one embodiment, for example, controller 122 alters the color of the transparent screen based on the location of the user"s hand. In FIG. 5 c, for example, controller 122 can cause an area around window 506 to glow as the user reaches the user"s hand towards window 506. This feedback helps the user interact with the windows in 3D space 206. In another embodiment, a 3D cursor can be displayed which is mapped to a position of the user"s hand or finger. In another embodiment, controller 122 can cause a part of the screen to not be rendered based on the location of the user"s hand to render an illusion of the user"s hand being in front of a virtual object.

FIG. 6 is a flow diagram depicting an example method 600 implemented by a transparent display device. Block 602 renders an image on a transparent screen of a computing device. For example, transparent display device 102 (FIG. 1) renders a 2D or a 3D image on transparent screen 124 of the transparent display device.

Block 604 receives 2D-input from a user via an input panel positioned behind the transparent screen. For example, transparent display device 102 receives 2D-input from a user via input panel 128 that is positioned behind transparent screen 124. Input panel 128 may include any combination of a keyboard configured to receive key-input, or a mouse, track pad, or touch pad configured to receive touch-input.

Block 606 modifies the rendering of the image based on the 2D-input from the user. For example, controller 122 controls transparent display device 102 to modify the rendering of the 2D or 3D image on transparent screen 124 based on the 2D-input received from the user via input panel 128.

Block 608 senses movement of one of the user"s hands to reach into a 3D space behind the transparent screen, and block 610 generates 3D-input based on the movement of the user"s hand. For example, hand tracker 126 senses movement of one or both of the user"s hand to reach into 3D space 206 (FIG. 2) behind transparent screen 124, and generates 3D-input based on the movement.

Block 612 slides the rendering of the image on the screen to reveal one or more virtual objects that appear to be in the 3D-space behind the transparent screen responsive to receiving the 3D-input. For example, controller 122 controls transparent display device 102 to slide the rendering of the 2D or 3D image displayed on transparent screen 124 to reveal one or more virtual objects that appear to be in 3D space 206 behind the transparent screen responsive to receiving the 3D-input from hand tracker 126.

FIG. 7 is a flow diagram depicting an additional example method 700 implemented by a transparent display device. Block 702 renders multiple windows stacked in one or more 3D volumes that appear to be in a 3D space behind a transparent screen. For example, transparent display device 102 (FIG. 1) renders multiple windows stacked in one or more 3D volumes, such as 3D volumes 502 and 504 (FIG. 5 a), that appear to be in 3D space 206 behind transparent screen 124.

Block 704 senses movement of a user"s hand behind the transparent screen to select one of the 3D volumes, and block 706 generates 3D-input based on the movement. For example, hand tracker 126 senses movement of the user"s hand behind transparent screen 124 to select 3D volume 504, and generates 3D-input based on the movement.

Block 708 renders the selected 3D volume as open to enable the user to interact with the multiple windows stacked in the selected 3D volume. For example, controller 122 controls transparent display device 102 to render selected 3D volume 504 (FIG. 5 b) as open on transparent screen 124 to enable the user to interact with the multiple windows stacked in selected 3D volume 504.

Block 710 senses additional movement of the user"s hand behind the transparent screen to select one of the multiple windows stacked in the open 3D volume, and block 712 generates additional 3D-input based on the additional movement. For example, hand tracker 126 senses additional movement of the user"s hand behind transparent screen 124 to select window 506 (FIG. 5 c) stacked in open 3D volume 504, and generates additional 3D-input based on the additional movement.

Block 714 renders the selected window as selected on the transparent screen. For example, controller 122 controls transparent display device 102 to render selected window 506 as selected on transparent screen 124, such as by causing window 506 to pop out of 3D volume 504.

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.

There are two main families of OLED: those based on small molecules and those employing polymers. Adding mobile ions to an OLED creates a light-emitting electrochemical cell (LEC) which has a slightly different mode of operation. An OLED display can be driven with a passive-matrix (PMOLED) or active-matrix (AMOLED) control scheme. In the PMOLED scheme, each row and line in the display is controlled sequentially, one by one,thin-film transistor (TFT) backplane to directly access and switch each individual pixel on or off, allowing for higher resolution and larger display sizes.

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.

Manufacturing of small molecule OLEDs was started in 1997 by Pioneer Corporation, followed by TDK in 2001 and Samsung-NEC Mobile Display (SNMD), which later became one of the world"s largest OLED display manufacturers - Samsung Display, in 2002.

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.

Organic small-molecule electroluminescent materials have the advantages of a wide variety, easy to purify, and strong chemical modifications. In order to make the luminescent materials to emit light as required, some chromophores or unsaturated groups such as alkene bonds and benzene rings will usually be introduced in the molecular structure design to change the size of the conjugation range of the material, so that the photophysical properties of the material changes. In general, the larger the range of π-electron conjugation system, the longer the wavelength of light emitted by the material. For instance, with the increase of the number of benzene rings, the fluorescence emission peak of benzene, naphthalene, anthracene,anthracenes, biphenyl acetylene aryl derivatives, coumarin derivatives,Ching W. Tang et al.Eastman Kodak. The term OLED traditionally refers specifically to this type of device, though the term SM-OLED is also in use.

Because of the structural flexibility of small-molecule electroluminescent materials, thin films can be prepared by vacuum vapor deposition, which is more expensive and of limited use for large-area devices. The vacuum coating system, however, can make the entire process from film growth to OLED device preparation in a controlled and complete operating environment, helping to obtain uniform and stable films, thus ensuring the final fabrication of high-performance OLED devices.However, small molecule organic dyes are prone to fluorescence quenching

Polymer light-emitting diodes (PLED, P-OLED), also light-emitting polymers (LEP), involve an electroluminescent conductive polymer that emits light when connected to an external voltage. They are used as a thin film for full-spectrum colour displays. Polymer OLEDs are quite efficient and require a relatively small amount of power for the amount of light produced.

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.

Although the shadow-mask patterning method is a mature technology used from the first OLED manufacturing, it causes many issues like dark spot formation due to mask-substrate contact or misalignment of the pattern due to the deformation of shadow mask. Such defect formation can be regarded as trivial when the display size is small, however it causes serious issues when a large display is manufactured, which brings significant production yield loss. To circumvent such issues, white emission devices with 4-sub-pixel color filters (white, red, green and blue) have been used for large televisions. In spite of the light absorption by the color filter, state-of-the-art OLED televisions can reproduce color very well, such as 100% NTSC, and consume little power at the same time. This is done by using an emission spectrum with high human-eye sensitivity, special color filters with a low spectrum overlap, and performance tuning with color statistics into consideration.

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 AM
