We can usually see a small number plate on the back or side of the auditorium chair. Although this number plate looks very inconspicuous, it is one of the auditorium chairs and its important accessories. Let's take a look at the mysteries of these small number plates.

There are two commonly used number plates, one is called seat plate, and the other is called line number plate. The seat plate indicates the number of the seat in each row arrangement, and the row number plate indicates the order of the row.

Commonly used materials for number plates include transparent PVC sheets and aluminum alloy sheets, etc. PVC sheets can be screen-printed on the bottom surface, and can also be made into a luminous effect. The aluminum alloy number plate is screen-printed on the surface and fixed on the seat with screws.

The line number plate is only installed at the edge of each row, which is the most common in cinemas. In addition to being similar to the number plate, there is also a line number plate with a light source, called aisle light, which has the function of indicating the row order In addition, it also includes the function of aisle low-light lighting.
