Abstract: A display panel assembly includes a display panel including an array of LED (Light Emitting Diode) pixels, and includes a support assembly configured to hold the display panel near the rear window of the vehicle. In one embodiment, the support assembly for holding the display panel in the vehicle includes a first strap and a first hinge. The first hinge includes: a first flap having a first hole; a pivot; and a second flap having a second hole and a third hole. The first strap includes a fourth hole and a fifth hole located at a hinge end of the strap, and a sixth hole located at a cross beam end of the strap.

Abstract: In one embodiment, a display panel includes a cellular modem configured to receive an image, a control circuit in communication with the cellular modem, an LED display in communication with the control circuit and configured to display the image through a rear window of a vehicle, a first voltage regulator; and a second voltage regulator. The LED display comprises a first set of LED modules and a second set of LED modules. The first voltage regulator is coupled to the first set of LED modules, and the second voltage regulator is coupled to the second set of LED modules.
