An optical path control device can include a first substrate having a first electrode disposed thereon, a second substrate disposed on the first substrate and having a second electrode disposed thereon, and a light conversion layer disposed between the first substrate and the second substrate and including a partition portion and a containing portion including suspended particles, where the partition portion and the containing portion are alternately disposed. The optical path control device can further include an adhesive layer disposed between the first substrate and the light conversion layer, a sealing portion disposed between the first substrate and the second substrate and surrounding the light conversion layer, and a dam portion disposed between the first substrate and the second substrate and disposed on an outside of the sealing portion.

A disposable film wrap system for use with handheld devices is provided. The cover film provides a protective barrier against human contact with a device and is intended to prevent the spread of microbial or viral particulates from the device to a device user. The system includes a primary film layer, a secondary film layer and film support layers. The film wrap system is embodied in a barrier applicator assembly that envelopes the device in the primary film layer. The secondary film layer is removably adhered to the primary film layer and disposed of by the end-user to expose the non-contaminated primary film layer. This feature ensures that any transfer of microbes or viruses that may have occurred during the wrapping process, by a person other than the primary user, are no longer present.
