1. A touch sensing apparatus, comprising:
a panel comprising a touch surface;
a plurality of light emitters arranged along a periphery of the panel;
a support structure positioned around the periphery of the panel, the support structure comprising a first portion extending over at least a portion of the periphery of the panel and separated by a space from the panel;
a sealing element fitted in the space between the panel and the first portion of the support structure, the sealing element configured to at least partially seal the plurality of light emitters from contaminants,
wherein the sealing element is sealable between the panel and the first portion of the support structure by being inserted into engagement with the first portion of the support structure.
