lcd module integrated transparent lcd free sample

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.

Screen Solutions offers complete solutions for transparent displays including standard and custom display cases. SSI has designed and built transparent displays for companies like Chrysler, Lockheed Martin, Mazda and many others over the last 15 years.

Standard Sizes start as small as 10″ and can get as big as 86″ Diagonal as seen in the video to your left. These complete displays include transparent panel, lighting, glass, display case and even a touch screen if you want.

Awesome little transparent OLED display. Its a 128x56 pixels and 1.51 inch diagonal. Super-bright, monochrome (light blue). We powered it up with a Seeeduino for this demonstration.

A large transparent liquid crystal display (LCD) prototype with ultrahigh transmittance and good see-through property is demonstrated in this paper. The transmittance reaches more than 20% by introducing the RGBW pixel arrangement, a thin color filter process, a large aperture ratio design, as well as antireflective polarizer film. The see-through image quality is also greatly improved by suppressing the blurring by using domain reduction pixel design. All these approaches are applicable for large LCD panel products, and we expect broad applications of large transparent LCDs in the near future.

The Arduino family of devices is features rich and offers many capabilities. The ability to interface to external devices readily is very enticing, although the Arduino has a limited number of input/output options. Adding an external display would typically require several of the limited I/O pins. Using an I2C interface, only two connections for an LCD character display are possible with stunning professional results. We offer both a 4 x 20 LCD.

The character LCD is ideal for displaying text and numbers and special characters. LCDs incorporate a small add-on circuit (backpack) mounted on the back of the LCD module. The module features a controller chip handling I2C communications and an adjustable potentiometer for changing the intensity of the LED backlight. An I2C LCD advantage is that wiring is straightforward, requiring only two data pins to control the LCD.

A standard LCD requires over ten connections, which can be a problem if your Arduino does not have many GPIO pins available. If you happen to have an LCD without an I2C interface incorporated into the design, these can be easily

The LCD displays each character through a matrix grid of 5×8 pixels. These pixels can display standard text, numbers, or special characters and can also be programmed to display custom characters easily.

Connecting the Arduino UNO to the I2C interface of the LCD requires only four connections. The connections include two for power and two for data. The chart below shows the connections needed.

The I2C LCD interface is compatible across much of the Arduino family. The pin functions remain the same, but the labeling of those pins might be different.

Located on the back of the LCD screen is the I2C interface board, and on the interface is an adjustable potentiometer. This adjustment is made with a small screwdriver. You will adjust the potentiometer until a series of rectangles appear – this will allow you to see your programming results.

The Arduino module and editor do not know how to communicate with the I2C interface on the LCD. The parameter to enable the Arduino to send commands to the LCD are in separately downloaded LiquidCrystal_I2C library.

Several examples and code are included in the Library installation, which can provide some reference and programming examples. You can use these example sketches as a basis for developing your own code for the LCD display module.

The I2c address can be changed by shorting the address solder pads on the I2C module. You will need to know the actual address of the LCD before you can start using it.

Once you have the LCD connected and have determined the I2C address, you can proceed to write code to display on the screen. The code segment below is a complete sketch ready for downloading to your Arduino.

The code assumes the I2C address of the LCD screen is at 0x27 and can be adjusted on the LiquidCrystal_I2C lcd = LiquidCrystal_I2C(0x27,16,2); as required.

This function turns off any characters displayed to the LCD. The text will not be cleared from the LCD memory; rather, it is turned off. The LCD will show the screen again when display() is executed.

Scrolling text if you want to print more than 16 or 20 characters in one line then the scrolling text function is convenient. First, the substring with the maximum of characters per line is printed, moving the start column from right to left on the LCD screen. Then the first character is dropped, and the next character is displayed to the substring. This process repeats until the full string has been displayed on the screen.

The LCD driver backpack has an exciting additional feature allowing you to create custom characters (glyph) for use on the screen. Your custom characters work with both the 16×2 and 20×4 LCD units.

To aid in creating your custom characters, there are a number of useful tools available on Internet. Here is a LCD Custom Character Generator which we have used.

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.

FIG. 8 illustrates various components of example device 800 that can be implemented as any type of client, server, and/or display device as described with reference to the previous FIGS. 1-7 to implement techniques enabling a transparent display device. In embodiments, device 800 can be implemented as one or a combination of a wired and/or wireless device, as a form of flat panel display, television, television client device (e.g., television set-top box, digital video recorder (DVR), etc.), consumer device, computer device, server device, portable computer device, user device, communication device, video processing and/or rendering device, appliance device, gaming device, electronic device, and/or as another type of device. Device 800 may also be associated with a viewer (e.g., a person or user) and/or an entity that operates the device such that a device describes logical devices that include users, software, firmware, and/or a combination of devices.
