The 2021 edition of the International Signs & LED Exhibition (ISLE) was held from May 10 to 13 at Bao’An New Hall of the Shenzhen World Exhibition and Convention Center. Two other trade shows also took place concurrently under the ISLE, which was the overarching event. These two trade shows were the International Smart Display & Integrated Exhibition and the International Signs & Smart Space Application Exhibition.

At this year’s ISLE, all-in-one system, smart retail displays, immersive displays, and UHD displays maintained their popularity and status as the mainstream products. Also, some display manufacturers were introducing some rather innovative solutions as a celebration for the 100th anniversary of the founding of the Chinese communist party.

UHD, Smart Applications, and Immersive Experience Competed for Attention

Notable companies that came to ISLE 2021 as exhibitors included Leyard Optoelectronic, Unilumin Group, Absen, Cedar Electronics, LianTronics, Ledman, LG Electronics, MAXHUB, AET, AOTO Electronics, NATIONSTAR, and Kinglight. Many exhibitions of individual companies at the event offered advanced, never-seen-before technologies that generated a lot of excitement among industry insiders.

Leyard

Among the fine-pitch LED displays that were shown at ISLE 2021, the prominent ones include the models under the TX and MG series from Leyard. These include the MG012 and the 135-inch TXP all-in-one videoconferencing system.

The MG012 is the vanguard model of the MG series. It is a spliced video wall that feature floating connectors for piecing together individual display modules in the most precise manner. The entire system is easy to set up and resistant to torsion and shock. In terms of performance, the MG012 supports 3D effects, HDR, and resolution adjustment. It also features 16-bit colors plus greyscale processing as well as technologies for color and brightness corrections.

The TXP videoconferencing system is a next-generation solution for medium- and large-sized smart displays deployed in conference halls and similar venues. The all-in-one design has resulted in a thinner display, with thickness reduced to as much as 20mm. The TXP features an interactive whiteboard with the latest touch technology, so writing on the screen can be done smoothly. All in all, this videoconferencing system provides a more efficient and intelligent approach to holding meetings.

In terms of innovations, Leyard brought several uniquely shaped or designed display systems to ISLE. One of them is called “Bravo Symbol” and is a rotating colonnade with the screen wrapped around all sides. The other is a large transparent video wall dubbed “Water Curtain Door”. Leyard also presented the LSX, a video wall that offers 3D visual effects in front of naked eyes.

Ledman

Ledman brought an 8K UHD Micro LED video wall, a 4K UHD video wall, the LEDHUB smart videoconferencing system, and a UHD immersive display. Together, these products showed off Ledman’s leadership in the UHD segment of the LED display market. Also, they all featured the COB packaging technology.

Among Ledman’s products, the one that attracted the most attention from the event attendees is the 324-inch 8K Micro LED video wall that adopts an LED packaging technology that combines COB with flip-chip. The video wall has a pixel pitch of just 0.9mm and a resolution that reaches 7680*4320.

The 8K Micro LED video wall also features 5G connectivity that, in turn, provides the speed and efficiency to enable the streaming of high-quality 8K content as well as a full-sensory experience. Ledman has stated that the 8K Micro LED video wall will make possible new digital applications in the field of broadcasting and entertainment.

MAXHUB

MAXHUB showcased numerous solutions related to smart control center, smart conference room, smart retail, and political information center.

The core of MAXHUB’s solution for large boardrooms is the MAXHUB Plus, an all-in-one display system with functions and features that cover all aspects of smart videoconferencing. This product promises a significant upgrade with respect to equipment control, audio-video technologies, user experience, and sensory experience.

Another MAXHUB’s solution called the MAXHUB Integrated LED Wall can serve as a unified control interface that can also adjust the brightness of the lights installed on the ceiling or lift window curtains. Furthermore, MAXHUB has developed its own software called Maxconfig. It syncs up mobile devices with its LED displays. Hence, users of MAXHUB’s products can use their smartphones or tablets to adjust display brightness, speaker volume, display color temperature, display mode, signal source, etc.

The MAXHUB Plus comes pre-installed with MindLinker, which is videoconferencing app that provides many useful functions such as attendance pass, reservation, sign-in, backdrops for virtual meeting, etc. The aim behind the development of this product is to build a smart central control system that monitor and manages the entire operation of a large conference room, thereby providing a more impressive and intelligent user experience.

AOTO

AOTO came to ISLE 2021 with solutions for flight information display system, displays for high-end retail stores, and large-size displays for conference rooms.

Regarding displays deployed at airports, the solutions for this venue have a higher standard for reliability compared with conventional in-door LED displays. In developing its LED displays for digital signage and flight information, AOTO places emphasis on lightness in weight, a consistent level of brightness across the screen, and accurate color reproduction. Hence, its solutions have been installed at many airports in China and other countries.

As for high-end retail, AOTO is offering a transparent display that can serve as a smart shopping window. It also features an intelligent assistant. This product, which was demonstrated at ISLE, proved that AOTO has the capability to expand into the high-end retail segment of the LED display market.

Turning to large-size displays for conference rooms, AOTO showcased solutions that can be installed in lecture halls and auditoriums. Among them, the SID “all-in-one” series is suitable for not only lecture halls but also training rooms, performance studios, and many other venues. The SID series adopts borderless design and an all-in-one body that keeps its weight down. It supports many types of digital media players and control schemes. In terms of specifications, the SID series has a resolution that maxes out at 1920*1080 and offers 100-550 nits in brightness.

Unilumin

At ISLE 2021, Unilumin exhibited a 5G-plus-8K solution, naked-eye 3D technology, XR-based immersive user experience, displays for broadcasting sporting events (and deployment in stadiums), and multimedia solutions for improving urban sceneries.

On the subject of XR (extended reality), Unilumin has integrated various related technologies into its LED displays. At this year’s ISLE, the company set up a massive LED video wall within its exhibition area. The video wall can livestream immersive 8K content via 5G network and allows viewers to interact with the content at the same time via XR technologies.

Unilumin is an official partner of FIBA, an official display supplier for the XXXI 2021 Summer Universiade in Chengdu, and a global partner of Manchester City F.C. Hence, it has an extensive line-up of products that can be deployed in stadiums and gyms. Some of these items that were shown at the trade show include a center-hung display system, a perimeter display system, and products that enable naked-eye 3D effects. To attract the interest of event visitors, the company also created a virtual bicycle ride with its LED displays. All in all, Unilumin demonstrated its prowess in developing LED displays for sports venues. At the trade show, the company presented a solution for every display application within a stadium.

Absen

In addition to Micro LED products, the highlights of Absen’s exhibition include such use cases as meeting and conference rooms, as well as innovative retail displays.

In particular, Absen presented a series of high-end Micro LED products for use in control rooms. These products are based on its in-house HCCI technology IP, feature flip chip COB packaging technology, are able to have uniform black color and high-contrast environmental lighting due to their improved video wall radiant power and improved cooling mechanism, and feature a host of other advantages, such as balanced, detailed images, high visibility, low power consumption, smart displays, and a thin-and-light physical appearance
