Abstract

Disclosed is a display device, elongate mount, and display module for displaying alphanumeric information to passengers of a mass transit vehicle. The display modules are mounted along a single edge to a elongate mount. The elongate mount includes at least one end cap which is made of a vibration dampening material. The louver of the display device includes a substantially continuous pressure member in order to place substantially continuous elongate contact to an area of an LED board that houses at least one heating element. The at least one heating element is covered by a thermally conductive foam that transmits heat from the elements to a heat sink of the display module.
