This invention is a major improvement on the current vehicle mobile advertising system. There are few options currently been offered on the market from back-lit printed plastic, magnetic stickers, hub caps, and scrolling LEDs. These systems work well but they often incur much higher cost over long period of time, to update these older systems one will need to reprint, re-install the signage over and over again, producing wasted materials, time and energy. Combining the usage of latest digital signage technology we are able to eliminate this higher incurred cost, and with LCD screens they are proven to be more effective medium of communication. To use this type of technology in the outdoor environment produced few problems, 1. LCD screens are sensitive to temperature changes, to solve this problem a continuous ventilation system with liquid bearing is added to the casing to provide cooling and ventilation of humidity. Custom made heating pads are added behind the screen for cold temperature operations to prevent LCD screen freeze ups. 2. Weather proofing the system against rain, snow and dust. This problem was solved using an ultra strong Aluminum casing to enclose the sensitive electronics; with 6 mm of tempered glass this creates a water proof environment inside the casing. 3. To reduce the weight of the system using Aluminum as constructive material. This has reduced the total weight of the working unit to 18 kg, which makes it safer and easier to be mounted on the roof top of a vehicle. The system itself is connected to a media player located inside the vehicle through VGA cable, the display system is not networked in any way, therefore reduces any chance of interference with vehicle's electronic system or GPS devices. Playback of the device is through a compact flash memory card, which can be updated quickly.
