One of the underground walkways between subway lines in central Shanghai now has a 112-meter-long fine pitch LED video display running along one wall.
Yes, a 2.5mm pitch LED wall longer than the length of a football field – American or soccer.
The LianTronics display is in the transfer passageway of Lujiazui station, on Shanghai’s newly-opened Metro Line 14. The 300-square-meter screen has a resolution of 44,928 by 1,056 and is touted as being the longest LED wall out there in a subway setting.
The wall has what LianTronics calls a “patented nano-coating” that gives it IP54-level protection against water, dust, static and humidity, and I assume that also means the coating – sometimes referred to as glue on board – will protect it from bumps and scratches from the bazillions of people who would be walking that concourse.
Update – From the comments below: This is a waterproofing and humidity proofing coating over the electronics which assist in product longevity. Glue on board or other epoxy type coatings are available as well but are different from these type of coatings.
The video and images provided were pre-opening, so they’re running manufacturer content. I assume this wall is for domination-level brand advertising sold either by the metro line operator or a media company. Even in China, a football field-length fine pitch LED wall costs a whole bunch of RMBs (Chinese currency).
