Description
LCD panels do not emit light on their own; they require a backlight to make the displayed images visible. Inverter transformers are a crucial part of the backlighting system in older LCD monitors and TVs.
TMS91429CT is Inverter Transformer For Samsung LCD 943NW.
In summary, an inverter transformer was a crucial component in older LCD displays with CCFL backlighting. Its purpose was to convert low-voltage DC power into high-voltage AC power required for powering the CCFLs that provided the backlighting for the LCD panel. However, with the transition to LED backlighting, the role of inverter transformers has largely been replaced by more efficient and versatile LED driver circuits.
