The presence of
lighting in the design of the rug.
This function is found mainly in top-end gaming models (see "Type"). The backlight does not affect the main functionality of the product, its role is primarily decorative. Perhaps the only situation where a luminous mat can be useful from a practical point of view is when working at a computer in the dark, when even the light from the screen does not illuminate the mat.
The backlighting capabilities can be quite advanced: it can have different colours and even react to individual user actions — for example, change colour depending on the mouse sensitivity set (such capabilities are usually available with high-end mice from the same manufacturer). The backlight requires power to operate; it is usually provided via a USB cable.
In this case, rugs are classified as
moisture -proof, which not only can tolerate moisture without any special consequences, but also quickly return to working condition. For example, a plastic or aluminium product can be simply wiped off; but the fabric is considered waterproof only if it has a high density and/or a special impregnation that prevents it from getting wet.
It is also worth noting that for many formally “waterproof” models, intense exposure to moisture is still undesirable: for example, an inexpensive plastic mat that is not wiped off in time can delaminate. And at the same time, on the contrary: many fabric models that are not moisture resistant can be washed and even washed without consequences (they will only dry for quite a long time).
