Abstract (en)
[origin: GB2567649A] A waterproof LED display panel which is particularly suitable to be mounted on a vehicle comprises a back plate 2, a transparent front cover 3, and a U-shaped edge gasket 4 interposed between the back plate 2 and the front cover 3. An L-section frame 5 holds the edge gasket between the back plate and the front cover secured by fixings which pass through the gasket. An array of LED display tiles 6 are supported on the back plate 2 preferably by tile guides in such a way that the tiles can move away from the tile guides whilst remaining held in a fixed relationship to the adjacent tiles in a direction parallel to the back plate, e.g. by means of magnets (25, Fig. 5) provided on the rear of each LED tile. Each tile 6 incorporates a DC-DC voltage converter and on-board diagnostic circuitry which monitors the LED tile's input voltage, DC-DC converter output voltages, LED current, and tile operating temperature. An interlock controller uses the diagnostic information from the tiles to reboot or close down the display panel in the event of a problem.
