LG Display Turns TV Panels, PC Screens Into Rich Sound Systems

At CES, the Korean company is showing off its 'Crystal Sound' technology, which does away with traditional speakers and instead delivers the sound directly from the display itself—whether it be a TV or a PC monitor.

LAS VEGAS—You won't need to hook up speakers with this flat panel TV from LG Display. It can vibrate the audio out right from the screen itself.

CES 2019 Bug ArtAt CES, LG Display is showing off its "Crystal Sound" technology, which does away with traditional speakers and instead delivers the sound directly from the display itself—whether it be a TV or a PC monitor.

LG Crystal Sound How it Works

LG Display originally debuted the technology back in 2017 with a 65-inch TV, but since then the feature has gone through some upgrades. The Korean supplier has now fitted a more powerful Crystal Sound system on an 88-inch 8K TV with the promise of delivering even richer audio.

To emit the audio, the 88-inch TV contains five "exciters" that have been fitted inside the panel. Each exciter can generate sounds and music outward through the display's vibrations.

PCMag had a chance to view the TV, and it does deliver some powerful audio. In a demo, the TV blasted the sounds directly toward us, right off the display. The TV is also capable of controlling how much sound each exciter in the panel emits. You can see how this works in the video above. As each car drives over the screen, the sound follows the path.

LG Display is also bringing the same Crystal Sound technology to PC monitors and laptop displays. It promises to swap the small and less powerful speaker systems that usually sit on the fringes of the computer for a louder, more immersive audio experience.

Unfortunately, LG Display is a supplier and a separate business unit from LG Electronics. So it'll be up to TV and PC makers whether they choose to adopt the Crystal Sound technology. But it's ready for manufacturing, according to LG Display.

What might this new tech cost consumers? LG Display is declining to speculate.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
