LGD showcased a new 48-inch flexible film-quality OLED screen with sound effects, showing the principle of screen sound technology

LG Display will release a self-producing 48-inch OLED display. Curved TVs have never really become popular, and unless you sit in the center of the screen, the viewing experience is not good. However, curved computer monitors are very popular (especially for gamers) because the viewer is usually sitting directly in the center of the screen and only tens of centimeters away. LG Display hopes to provide computer users and gamers with the best of both worlds. This display can be bent for gaming, flattened for watching TV, and can produce sound by vibrating the screen instead of using traditional speakers.

During CES 2021, LG Display will showcase a new 48-inch flexible film-quality OLED (CSO) screen. The company stated in a press release that this "thin paper" display can be bent to a radius of curvature of 1,000 millimeters and still provide "an even viewing distance from the middle to the edge of the screen." LG Display stated that, like this OLED screen, its "response time is 0.1 millisecond (ms), the refresh rate is 120Hz per second, and a wide variable refresh rate range from 40Hz to 120Hz."

IT Home understands that this new screen will also use LG Display's CSO technology to produce sound. The CSO screen was first shown at CES in 2017, using an exciter installed behind the display to vibrate the OLED screen itself to generate sound waves, and the display essentially becomes a speaker. The vibration exciter in the new 48-inch bendable film-quality OLED display is only 0.6 mm thick, compared to 9 mm when the CSO was first introduced four years ago.

"LG Display’s 48-inch flexible CSO display is optimized for gaming because it maximizes the use of advanced technology and creates another level of immersive experience. In other words, it provides gamers with The best gaming environment.” Dr. Chang-ho Oh, Executive Vice President and Head of TV Business Unit of LG Display, said at the press conference.
