Mediamesh
Mediamesh® : Transparent platform for complex content.Mediamesh® is a unique patented system used for the medialization of large facade surfaces and it is perfect for displaying videos, graphics, text animations, and changing colour effects etc.
Mediamesh is desingned to provide 60% to 90% transparency and the video display can only be seen from outside of the building, so it doesnt block your windows or distract the residence of the building, This is one of the major advantage of the Mediamesh.

Stainless steel wire mesh with interwoven LED profiles provides a permanent, integrated and intelligent medialization of architecture. In an alliance of strengths, GKD and ag4 have developed Mediamesh® as a system that combines all the product advantages of wire mesh and IT-based LED technology.
The basis is a woven cable mesh, for example, GKD'smesh type "Tigris". Sleeves are woven into its warp cables at predefined intervals. These form the mechanical interface for special round profiles into which the LEDs are inserted and sealed with a waterproof resin. The profiles, open at the front, are inserted into the sleeves in the cable mesh which is woven to the specified width and length. 16 of these profiles are interconnected by cables. Completely prepared and finished, the Mediamesh® is rolled up and transported to the building site ready for installation.
After the installation, the supply of power and data to the LEDs is handled by control units - consisting of a power source and electronic components - which can for example be concealed in the ceiling and connected to a central server located in the building.

Once all the cables have been connected the Mediamesh® display can be operated via the Internet - in an unusually generous color depth of 36 bit at a frame rate of 400 Hz. Power consumption for a 2,000 sqm façade will average 70 to 90 kW/h; for 500 sqm 15 to 22 kW/h. Maintenance is also uniquely simple within the patented construction of Mediamesh®: individual LED profiles or control units can be easily replaced if necessary.
Mediamesh® can be woven and finished in any size or special shape, individually tuned to the envisaged application and the image quality required. The medialized mesh can be used around the clock for any kind of display, ranging from simple
graphics to video quality. The decisive factor for the image resolution is the ratio of horizontal (from 4 to 40 cm) to vertical pixel intervals (from 6 to 40 cm): the denser the pixels, the finer the resolution. Another important factor is the viewing distance of the spectator: the closer one stands to the image, the closer the pixels must be to each other.
For reasons of cost efficiency, it may be advisable to reduce the pixel density in the mesh. For example, for graphics a minimum viewing distance of 20 m is recommended and ideally a distance of 50 m or more. With the appropriate resolution a display can be seen from as far as several kilometers. Here individually tuned display software compensates for the lower resolution.
Generally speaking there are three planning parameters which determine the specific technical construction of Mediamesh®: the viewing distance, the size of the media surface and the type of video display software.
In contrast to LED boards and temporary single pixel systems, Mediamesh® is permanently weather and temperature resistant - it can even be installed beneath an ice surface. The mesh, adapted to the individual architecture and equipped with pixels that can be triggered individually, has no particular effects on the façade construction owing to low surface weight and wind loads imported to the structure. Another relevant aspect - especially in the case of large surfaces - is the considerably cheaper installed cost of Mediamesh®. In contrast to LED boards, conventional media formats like 16:9 and 4:3 do not have to be complied with. This flexibility of formal alignment allows this new electronic media to be integrated into architecture without compromising its design proportions. Thanks to the extraordinary appearance of the stainless steel mesh carrier structure, Mediamesh® is the only pixel-oriented media façade system which functions both as a spectacular medial skin and, when switched off, as a decorative mantle. The lightness of the integrated LED technology preserves the textile-like transparency of the wire mesh and transforms it into an intelligent platform for complex visual content. The system really shows its magic when logos or animated symbols appear in isolation on the transparent wire mesh. Then they form a mysterious overlay which perfectly fuses the architectural reality behind the mesh with a world of virtuality.
