LG is building AI into smartphones, televisions, refrigerators, and even air conditioners. Chief technology officer Dr. I.P. Park explains why. : LG makes a lot of products. So many, in fact, that the South Korean company’s nearly half-dozen subsidiaries — LG Electronics, LG Uplus, LG Innotek, LG Chem, and Zenith, to name a few — semi-autonomously handle research, development, testing, and manufacturing full stack. Just a sampling of the electronics in its portfolio might include televisions, refrigerators, ovens, smartphones, home security cameras, computer monitors, and microwaves — and that’s just scratching the surface.
