Technology update ISE roundup: digital signage innovations


While collaborative technologies are still a relative newcomer at ISE, digital signage has been an ever-present for the last decade. While there is a general increase in demand across the signage spectrum, the need for novelty among existing users ensures a raft of innovative new solutions at each major trade show. ISE 2017 was no exception.


For the digital signage integra- tor on the lookout for some- thing new, the OLED and direct LED technologies on show at ISE 2017 would have attracted their interest. While it was orig- inally announced in time for In- foComm 2016, ISE was many visitors’ first chance to see So- ny’s CLEDIS (Crystal LED Inte- grated Structure) technology.


CLEDIS


This is a large-scale canvas solution, that builds on Sony’s self-emitting display capabil- ities, but with ultrafine LEDs as the light source. “Our new technology is a giant new type of canvas for unprecedent- ed flexibility and creativity in high-end visual simulation and entertainment,” said Damien Weissenburger, Business Head of Corporate & Education Solutions at Sony Professional Solutions Europe. “Compared to other solutions currently available for large-scale display


180 degree viewing angle. This self-emitting display technol- ogy uses R (red), G (green), and B (blue) ultrafine LEDs mounted on the display sur- face, with each pixel emitting light independently. Each pixel is composed of one separate R, G and B ultrafine LED, with the light source only 0.003 mm2 in size. The remaining surface area is more than 99% black. The technology’s isotropic lu- minescence is said to deliver the same colour reproduction and brightness for viewers at any angle. The high black-to- surface ratio delivers a high contrast ratio in both light and dark viewing environments. The surface-mounted light source also dramatically improves the efficiency of light used, with corner-to-corner image unifor- mity in terms of brightness and colour, even on a large screen. A brightness rating of 1000 cd/ m2 (1000 nits), producing im- agery with 10-bit colour depth and a wide colour gamut (ap-

global digital signage market is valued at $14.9 billion, with a projected annual growth rate of eight percent. The market is projected to grow to $21.9 billion in value by 2020. In terms of global digital signage unit sales Samsung has ranked number one since 2009, and having extended its global mar- ket share to 28.1 percent in 2015. The

innovations included two ad- ditions to its SMART Signage range – the quantum-dot QLED Signage UHD displays and the fine pixel pitch IF Series LED signage. Of the two, Samsung’s QLED Signage UHD displays (55- and 65-inch models) is arguable the more innovative. The quantum dot integration enables Samsung’s new QLED Signage to balance light and dark brightness and preserve gradation

it’s a leap forward in depth, contrast, wide viewing angle, colour, resolution – and pure visual impact.”


The new canvas technology is designed for a range of com- mercial applications where in- tricately detailed video displays and realistic simulation is re- quired on a large scale. Appli- cations are said to range from industrial product design and manufacturing for automotive, through to displays in theme parks, museums, high-traffic lobbies and showrooms, as well as boardrooms and broadcast studios.


CLEDIS offers a borderless design, allowing multiple tiles to be seamlessly aligned so no visible gaps can be seen. The result is an immersive, true to reality picture with a near


proximately 140% of sRGB). The scalable canvas is made up of multiple display units (each measuring 403 mm × 453 mm) that can be joined to- gether to create a large-screen display with a size and aspect ratio dependent on the applica- tion. The display units have no borders, so can be combined to create immersive, large screen visuals

that is said to be deeper and more realistic than that offered by conventional alternatives. These refinements produce deeper blacks, sharper whites and more precise colours re- gardless of surrounding room lighting. Beyond


an enhanced pre-


sentation, the QLED Signage displays offer business users greater flexibility to share con- tent. Suitable for both land- scape and portrait orientations, the QLED Signage

provide a wide viewing angle capable of attracting custom- ers from a distance. Designed for long-term performance, the QLED Signage displays also represent a sustainable, ener- gy-efficient alternative.


Samsung IF series


As LED signage gains in pop- ularity, Samsung’s fine pixel pitch IF Series LED displays


(P1.5, P2.0 and P2.5 models) are described as providing an ideal combination of excellent picture quality and intuitive management. Scheduled for full release very soon, the IF Series LED displays combine Samsung’s industry-best video processing and picture tuning technologies with a host of cus- tomised features to add realism and detail to static and inter- active

content. Through spe- cialised scene adaptation, each IF Series LED display analyses and fine-tunes grayscale levels within each frame to maximise contrast, and remove glare and visual


distortion. A comple- mentary dynamic peaking set- ting enables displays to achieve peak brightness levels up to two times higher than that of standard LED maximum bright- ness specifications.


The IF Series LED design is best described as a minimal- istic design, offering both full- front and rear access. Users can enjoy convenient, quick- turn maintenance without sac- rificing a neat and seamless installation. The advanced cabinet structure eliminates the LED module and catwalk space


gaps that accompany


more challenging frontal lay- outs. This alignment ensures improved picture uniformity regardless of cabinet and LED module positioning. The IF Series’ user-friend- ly design allows the displays to "get up and running" fast- er, and with minimal ongoing maintenance required. Sam- sung’s complementary LED Signage Box (S-Box) transmits UHD content across multiple screens without requiring ex- pensive


splitters or external


conversion boxes. Users addi- tionally can configure signal redundancy through their exist- ing cable structures, and con-


LG has really pioneered OLED as a commercial display tech- nology, and used ISE 2017 to show innovations including LG’s Flexible Open Frame OLED and In-Glass Wallpaper OLED, plus its new Ultra Stretch LCD sig- nage solutions. OLED technol- ogy allows screens to emit light without the need of backlight- ing for superb images with the deepest possible blacks, while providing wider viewing angles than conventional backlit dis- plays. OLED displays are both thin and flexible, and LG says that its next-generation Flexi- ble Open Frame OLED signage will allow customers to change the curvature of their instal- lations in either landscape or portrait modes. The curvature of the screen can be changed even after installation, allowing for both convex and concave displays.


OLED solutions demonstra- tion included the 65-inch Du- al-View Curved Tiling OLED sig- nage. The display consists of eight connected double-sided, flexible OLED. Each panel of- fers 4K Ultra HD image quality, with 3,840 x 2,160 individual pixels with system on a chip (SoC) and 128GB of internal memory working


together to


deliver perfect UHD playback, without the need for a separate PC or media player.


Designed with dual-sided ul- tra-slim OLED panels in a glass pane, LG’s In-Glass Wallpaper OLED signage is perfect for boutiques,


art galleries and other businesses that want to Continued on P12
