final result of digital video wall display

Context / environment

Street Co’, has been contacted by Daiwa House group to help to develop this LED wall in the main lobby of their building located in Tokyo.

After a long brainstorming session, Daiwa House groups’ design team has finally decided to create some functional and innovative digital LED touch display in the lobby entrance,

creating one of the most visually dynamic and stimulating commercial real estate spaces in the city.

Creating this unique display in their lobby will absolutely help the newly created building to entertain visitors, partners, and customers. This LED wall display has the objective of helping to retain customers and bring them a fun and playful environment.


For this project, we used our small pitch indoor product Pitch 2.6. This product was particularly suitable because of its ability to realise any shape with ease. So we built 2 LED wall display screens of 26.5sqm based on 2.6 pitch.

Here are the advantages of the product

  • High contrast and good colour reproduction, outstanding image quality

    Weights only 8.5 KG

    Full front and rear installation and maintenance

    1. Front maintenance: modules and power box can be easily dismantled via the maintenance tool from the front of the screen
    2. Rear maintenance: the magnetic power box cover can be opened in 2 seconds, maintenance efficiency is also much higher

    Multiple installation ways available

    Using this product is particularly suitable as there are many options for installation

    • 1.Wall surface mounting to save space
    • 2.Stacking
    • 3.Hanging

    Flexibility and creative possibility

    1.Curved angel degree:±7.5°、±5°、±2.5°、0° (Curve system optional)

    2.Dislocation splicing available

    Standardized modules

    1. There is only one standardized module and it is compatible with different cabinets
    2. One cabinet can use multiple modules, each with different pixel pitches

    Single person operation

    One person can install and dismantle the cabinets, saving both time and labour.

    How to build a digital waterfall LED wall display screen for a lobby


    Transforming a sterile area of plain beige, taste-less wall, with a 46sqm LED screen, It was installed to liven the place up and bring an uber-dynamic sensory experience to an otherwise quite ordinary commercial office lobby. Options for visually magnetic motion content are endless within such a vast and custom LED shape canvas, Our clients partnered with a design company to Digitally create an innovative optical animation.

    The Water Wall is a hyper-realistic cascade of water – essentially and literally a fluid visual simulation. The concept is in direct harmony with the huge screen’s shape, with the added visual riddle of splash ebbs and flows around edges.

    A synchronous sound design further captures the energy of a bustling and, at times, bursting active lobby space.


(1) Fluid Dynamics Challenge: True-to-life fluid dynamics using only computer-generated graphics was a major challenge.

(2) Motion Challenge: Because of the powerful intensity and the rapid, dense visual texture of rushing water, it was important to create a realistically eye-catching experience but not one so ferocious that it would create vertigo or motion-sickness in viewers.

(3) Rendering Challenge: The massive template (3K resolution) for the Water Wall created a huge challenge for rendering the final video.


(1) Real-time physics engines were created to perfect the natural movement of water. This produced such realistic-looking water that it even fooled many people on social media, who believed it was a waste of water. In fact, no water was used in the creation of the piece.

(2) The actual speed of the Water Wall had to be slowed down to be both soothing and believable.

(3) For the massive render, a render farm was used, running more than 70 servers for three weeks to complete the project.


The Water Wall creates a sensation of pure energy as the visual and aural rush of water generates a feeling of fresh anticipation and carefree exuberance. Every day, people walk through the doors of the lobby only to snap a photo on their smartphones. It’s definitely something the passersby and visitors haven’t seen before.

Our LED wall display screen is very similar and was inspired by the Salesforce video wall display in San Francisco lobby’s building.

Impact : taking advantage of DIGITAL VIDEO WALL DISPLAY

Cartier is a Luxury brand working with high standards.

Having a flush and curved LED wall of high definition and high density of pixel could be a challenge.

It would have worked for a low-resolution type of video content but not in this particular context.
