An interchangeable display system and method is provided. A first and second side assembly are each selected from a number of: digital side assemblies each comprising an electronic display, static side assemblies each comprising a poster cavity which accepts signage, and cover side assemblies. The first and second side assemblies are interchangeably mounted to a frame. When one of the side assemblies is in need of replacement, it is removed from the frame and a replacement is installed.

A display system is configured to be mounted to a vehicle, the system including a display and one or more sensors. The display system may be configured to determine, based at least in part on data from the one or more sensors, a speed of a vehicle to which a sign is coupled. Based at least in part on the speed of the vehicle, the display system may position the sign in a first position based at least in part on the speed of the vehicle being less than a threshold speed, or a second position based at least in part on the speed of the vehicle being greater than or equal to the threshold speed.

A micro-LED module is disclosed. The micro-LED module includes a flexible circuit board and a plurality of LED pixels mounted on the flexible circuit board. Each of the plurality of LED pixels includes a first micro-LED chip, a second micro-LED chip, and a third micro-LED chip. Each of the first micro-LED chip, the second micro-LED chip, and the third micro-LED chip has at least one side whose length is 100 m or less. Each of the first micro-LED chip, the second micro-LED chip, and the third micro-LED chip includes one or more electrode pads having a width of 80 m or less on the surface facing the flexible circuit board. The flexible circuit board includes a first flexible insulating film including electrode patterns formed on the upper surface thereof and connected to the electrode pads through solder bumps having a diameter of 80 m or less and a second flexible insulating film connected to the bottom of the first flexible insulating film through a first conductive pattern. The first flexible insulating film includes a first via hole having the same cross-sectional shape and area from the upper to the lower end and a first via formed in the first via hole. The first via hole of the first flexible insulating film is connected to a portion of the first conductive pattern.

A vehicle mountable holographic promoting system and method of use; the vehicle mountable holographic promoting system includes a body with at least one light, a mount, and a controller in communication with a software application and the body. The body is mountable to the vehicle via the mount. The mount is able to be removably attachable or otherwise secured to roof of a vehicle. The controller controls the body such that the body is able to visually promote via an image display at least one promotable item using the at least one light. The promotable item appearing to float on a plane above the vehicle.

A field serviceable and interchangeable display system and method is provided. A first and second side assembly are each selected from a number of: digital side assemblies each comprising an electronic display, static side assemblies each comprising a poster cavity which accepts signage, and cover side assemblies. The first and second side assemblies are interchangeably mounted to a frame in a hinged fashion. When one of the side assemblies is in need of replacement, it is removed from the frame and a replacement is installed.

Systems and method are disclosed which provide an inconspicuous electrical pathway between one or more electronic displays of a vehicle top unit and a power source for a vehicle. A housing for the electronic displays is mounted to a cross bar mounted to a roof of a vehicle. Festoon type wiring extends from the power source, along a black mask area of a windshield, along or through the cross bar, and to the housing. Double sided adhesive tape is positioned between said festoon wiring and a front surface of the windshield.

A first and second display assembly are moveably mounted to a frame. At least one of the display assemblies includes a cover, an electronic display located behind the cover, and a first and second channel. A fixed plate is attached to the frame and positioned entirely within a cavity located between the display assemblies and the frame. The cavity and the first channel are part of a closed loop pathway, while the second channel is part of an open loop pathway. The closed loop is sealed when the display assemblies are in a closed position, and the fixed plate is accessible when the display assemblies are in an open position.

A vehicle lighting system is provided primarily for use with emergency response vehicles. The vehicle lighting system includes at least one luminescent planar sheet affixed to a vehicle's mounting surface. The luminescent planar sheet includes a non-luminescent printed circuit board in the shape of a letter or number which has a top surface of a color which contrasts with the mounting surface's color. The luminescent planar sheet includes a plurality of light emitting LEDs which are surface mounted upon the printed circuit board so as to be arranged in the shape of the desired letter or number with the LEDs covering no more than 20% of the printed circuit board's top surface. Preferably, the LEDs cover no more than 7% the printed circuit board's top surface.

This technology relates to a display mounted messaging system. The display mounted messaging system may include a light emitting diode (LED) display attached to a housing of a sensor. The housing of the sensor may rotate. The display mounted messaging system may also include an LED controller which is configured to selectively activate and deactivate at least one LED in the LED display, to provide a message in the direction of an intended recipient.

An ice re-conditioning assembly includes a vehicle that is driven on ice in an ice skating rink. A drive unit is coupled to the vehicle for driving the vehicle around the ice skating rink in a pre-determined route. A plurality of resurfacing units is each movably coupled to the vehicle. Each of the resurfacing units is urged into a deployed position to engage the ice for reconditioning the ice for skating. Each of the resurfacing units is urged into a stored position has each of the resurfacing units being contained within the vehicle and being spaced from the ice. A plurality of displays is provided and each of the displays is coupled to the vehicle. Each of the displays displays indicia comprising words and images for advertising purposes.
