In a display apparatus and a method of assembling the display apparatus according to one or more embodiments, a printed circuit board is electrically connected to a lower end of a display panel and disposed in a rear surface of a container. An electronics module is programmed with a temperature performance profile for the cartridge. A scanning device has at least one scanning mirror that is irradiated by the correction radiation and driven in such a way that a defined portion of the optical surface of the optical element is scanned with the correction radiation. The fiber distribution system also contains a cable guide tray for supporting the fiber cables and the system includes a plurality of radius limiters to minimize cable bends.
