TV (LED/OLED) power

Liquid Crystal Display (LCD) technology that relies on a backlight is the MOSt common technology in the TV market now. Also there is high-end LCD options like QLED (Quantum Light Emitting Diode) TVs, which are basically LCD TVs with LED backlights. New generation OLED TVs has outstanding image quality regarding dark and bright ends of the spectrum, various user interface. Therefore OLED TVs require higher power than traditional TVs (LCD/LED).

TV power supplies require low stand-by power consumption and low profile to maintain the slim TV design.

Topology Trend

PFC : CCM PFC → Dual Boost, Totem Pole PFC
