The Conical MediaWall – a 15 metre high and 

24 metre wide 3D puzzle solved 

with IP X-Pipe



Hysan Place is the new flagship development by Hysan, Causeway Bay’s most significant developer of high-end retail and office properties. Given the considerable competition in this entertainment and shopping hub, Hysan Place needed something unique for its grand entrance – a proclamation to the world that indeed one had ‘arrived’ to a place like no other. This led to the genesis of the Conical Media Wall; a vast electronic integrated façade which forms the arch under which most visitors will pass. The design and construction of the Conical Media Wall was the collaborative brainchild between Joseph Gartner Hong Kong – a leading façade engineering company and Illumination Physics.


The shape was immediately problematic as the overhanging façade is formed in the contour of a truncated and inverted cone 15 metres high and 24 metres wide. This created a three dimensional puzzle that no conventional modular media wall product could match.
Illumination Physics solved the problem with one of its linear media wall products IP X-Pipe. This is a linear tubular LED product that is vertically mounted in separate rows. The distance along the vertical pitch of the LED was fixed at 40mm. The distance between the horizontal rows varies imperceptibly from 80mm to 110mm in order to best suit the conical dimensions.


Some customisation was required to match the dimensions of the Conical Media Wall. The linear product was orchestrated in such a way that the width between the modules diverged slightly whilst the height followed the divergence of the wall itself. Although the horizontal pitch changes from 80mm at the base to 110mm at the top, the change is not perceptible as the viewing distance and the effects of parallax cancel out the increase in horizontal pitch. The change in pitch is accommodated for in the mapping software called IP Xsoft which controls the images and video files played on the wall. 
The concept of the varying horizontal pitch solved a key problem therefore allowing Gartner to design the aluminium cladding panels to accept the IP X-Pipe rows in a predetermined way. The panels were created with a mounting channel for the LED, which were fitted on-site after the panels had been erected. A decorative cover plate was then fitted between each row of LED to conceal the mounting brackets.
The Conical Media Wall is over 15 metres high and up to 24 metres wide at the top. Two-hundred and seventy-four rows of IP X-Pipe were used. The vertical dimension was too long for one driver to control an entire row, so the display was divided into two halves. Two drivers were required for each row; one positioned at the top of the wall and the other at the base. All of the equipment has been cleverly concealed behind the cladding panels
The Conical Media Wall is activated at 4pm each day and is a wonderful example of what can be achieved with the ability to customise a LED display product to suit a very specific application. The result is a fully integrated and captivating feature.
