[Asia Economy Reporter Ki-min Lee] LG Display announced on the 14th that it has succeeded in registering the national standard (KS) for the 'sound-emitting display' of the OLED display 'CSO (Cinematic Sound OLED)' that produces sound through its own vibration.

The sound-emitting display is a technology that can only be realized by OLED displays with a thin single-layer structure that emits light by itself. The display acts as a diaphragm to produce sound. Because the sound comes directly from the display, it feels as if the characters on the screen are speaking directly, providing high immersion and a sense of presence.

Existing standards were created based on conventional speakers, so there were limitations in objectively evaluating and measuring the advantages unique to sound-emitting displays.

In a situation where global competition among companies is intensifying, it is essential to create and secure nationally certified standards to become a leading technology in the global market.

Accordingly, LG Display established a dedicated organization in 2018 to promote standardization and develop evaluation methods that can objectively quantify the advantages of CSO and establish certified standards. With this national standard registration, CSO is expected to rapidly expand into various markets such as digital signage following OLED TVs.

The National Institute of Technology and Standards sees CSO playing an important role in leading the global OLED display market. Therefore, CSO was selected as a 'promising new industry international standard development project,' and efforts will be made to register it as an 'International Electrotechnical Commission (IEC) international standard' to strengthen global technological competitiveness and secure market leadership.

Yoon Soo-young, Executive Vice President and Chief Technology Officer (CTO) of LG Display, said, "In the era of standard wars to secure the global market, it is highly meaningful that CSO's technology has been recognized through the registration of the sound-emitting display standard, which has infinite scalability and marketability." He added, "We will continue to strengthen our technological leadership through continuous innovation and lead the next-generation OLED market."
