ABSTRACT:
A flyback transformer for a display device circuitry is provided. The flyback transformer has a low voltage bobbin, a high voltage bobbin, a core and a casing, and the casing includes a slot. The flyback transformer is characterized in that the flyback transformer comprises a pin inserted within the slot of the casing with two ends of pin sticking out from two end openings respectively, and functions to generate a positive flyback pulse signal and a negative flyback pulse signal at two ends thereof respectively during a flyback operation of the circuitry. An insulating portion is provided between the pin and the core. Wherein, a side edge of the low voltage bobbin comprises a connection portion for insertion into the slot of the casing and functions as the insulating portion.
