Where the COB EF Series Is Used

The EF Series is an outdoor fixed installation built around a fine pitch rather than a long viewing distance. It suits positions where the audience gets close to the screen and the environment is bright: flagship store facades, shopping street frontages, transport concourses, and building entrances that face daylight.

It is not the right product for rental or touring work. Those projects need a lighter cabinet, faster locking and a flight case, which is what the COB Z series covers. Choosing the wrong one usually shows up as handling damage rather than as a picture problem.

Choosing Between P1.56 and P1.95

The two pitches share a 500×500mm cabinet, so the decision is not locked in at cabinet level — the same frame accepts either module. What changes is the closest usable viewing distance and the cost per square metre.

Set the pitch from the nearest position a person will stand, not from the far side of the street. If customers can walk up to the glass, a finer pitch is justified; if the closest viewer is across a road, the coarser option delivers the same impression for less. Where a site has both close and distant viewing, the mixed-pitch capability lets one wall prioritise the close view without rebuilding the structure.

Questions Buyers Ask Before Ordering

Why COB rather than SMD outdoors?

The chip-on-board surface is bonded and sealed rather than built from individual lamps, so there is no lamp to knock off and the face wipes clean. On a street-level screen that people can reach, that difference matters more than a small brightness advantage.

How is it serviced?

Modules are front-accessible from the face of the screen, so a repair does not require access from behind the wall — a decisive point on a building where the rear void is occupied by other services.

What should be confirmed before the order?

The measured daylight level at the screen position, the nearest viewing distance, the mounting method and the delivered cost to site. Send the position and we will confirm the pitch and issue a cut sheet with dimensioned drawings.
