A back panel for a display device, such as a flat-panel television or computer monitor, which is very thin around the edges and houses all electronics in a 'spine' near the vertical center of the back of the display. The back panel provides novel heat-dissipation, arrangement of electronics to save space, forces the center of gravity forward allowing the display to be set closer to a wall, and provides less interference and signal degradation than the prior art.

Back panel for video display device

An AC inverter circuit supplies power to multiple lamps in an LCD backlight. Conventional AC power is used as direct input into a full wave rectifier that converts the input from AC to a DC reference voltage. A transformer driver, including a chopper, converts the DC reference voltage to a higher voltage AC which drives a step up transformer to produce a voltage sufficient to drive as many as six fluorescent lamps. The components/circuitry associated with the transformer's primary windings is optically isolated from the rest of the circuit.
