Editing Flyback transformer (section)

==Practical considerations==
In modern displays, the LOPT, voltage multiplier, and rectifier are often integrated into a single package on the main circuit board.  There is usually a thickly insulated wire from the LOPT to the anode terminal (covered by a rubber cap) on the side of the picture tube.

One advantage of operating the transformer at the flyback frequency is that it can be much smaller and lighter than a comparable transformer operating at mains (line) frequency. Another advantage is that it provides a [[Fail-safe|failsafe]] mechanism — should the horizontal deflection circuitry fail, the flyback transformer will cease operating and shut down the rest of the display, preventing the [[screen burn-in]] that would otherwise result from a stationary electron beam.
