LG has developed OLED lights that double as speakers

23 Mar 2018 | Rasmus Larsen |

LG Display has adopted its ’crystal sound’ technology first introduced in Sony’s A1 OLED TV for lighting solutions. The actual OLED light panels serve as speakers.

Lamps as speakers

At CES 2017, Sony wowed visitors by introducing the first OLED TV with a speaker built directly into the OLED panel. It has since become clear that the technology is mostly the work of LG Display.

LG Display refers to the technology as ’Crystal Sound OLED’, or simply CSO, and for the first time ever this technology has now been embedded directly into OLED light panels, meaning that you can effectively use the lamps in your house as speakers.

- “LG Display will introduce its Crystal Sound OLED (CSO) Lights by extending the use of its CSO technology used for its TV panels to OLED light panels for the first time in the world,” the company announced.

Ultra-thin OLED light panels

LG’s OLED lighting solutions are based on a very thin substrate that can be “twisted and rolled up to a 30mm radius of curvature without compromising any functionality”. It has a thickness of just 0.41mm.

So how does it produce sound? LG explains.

- “The paper-thin OLED light panel itself serves as a speaker diaphragm with the sound emanating directly from the panel, which is vibrated by exciters attached to the back. A flexible, natural lighting installation that also serves as a speaker not only delivers futuristic design and natural illumination, but also premium sound - hence the name.”

The company imagines that the new technology will ”be widely used in AI-integrated mood lamps and ceiling lamps that will be able to talk with you as well as light up your life”.

LG Display recently increased production capacity for OLED lighting panels by 30 times and is planning further capacity expansions in the near future.

- ”We are glad to be able to produce 30 times the capacity of lighting as before and are confident that Luflex will soon be lighting up spaces all around the world,” said Sung Soo Park, Head of the OLED Light Business Division, LG Display.

We have seen LG’s OLED lighting products (Luflex) before but not yet had a chance to hear the CSO-enabled versions. What we need now is a fully wireless audio platform to take advantage of all these lamps that LG hopes to sell you. The products are currently being exhibited at Light & Building 2018 in Frankfurt.
