LG Electronics announced a new in-vehicle software platform built on Google $GOOGL's Android Automotive OS, sending LG Electronics stock up as much as 23.95% in Seoul trading.

Rather than dedicating separate hardware to each screen, the platform uses one system-on-chip to drive multiple in-car displays of different sizes — a departure from conventional multi-display architectures — and it operates on Qualcomm $QCOM hardware. Deploying multi-display cabin setups becomes less expensive under this architecture, LG said.

The platform supports individualized experiences for each passenger. A driver can use navigation on the main display while a front-seat passenger watches YouTube and rear passengers view other content. The system also supports individual user logins, personalized settings, content sharing, and parental controls, the company said.

LG also updated its voice command interface, letting users adjust screen layouts, launch apps, control vehicle functions, and manage audio volume through spoken commands — a feature the company said improves safety by reducing reliance on touchscreens.

Google's Patrick Brady, vice president of Android Automotive at Google, publicly endorsed the system. "LG's solution clearly demonstrated how AAOS can enable more flexible, intelligent and engaging in-vehicle experiences," Brady said in a statement. "Its seamless multi-display integration, intuitive voice controls and stable performance powered by a single SoC stood out, and we look forward to continuing our collaboration with LG to advance innovation for the SDV era."
