Research on OLED Panel Exciter Speakers for New Sound Experiences in Vehicle Interiors

The advancement of display and semiconductor technologies has facilitated the mass production of OLED panels. Research initiated in 2017 has led to the development of a novel sound emission system called Crystal Sound OLED (CSO), which involves directly vibrating the OLED panel to produce sound. This innovation has spurred various technological enhancements aimed at improving the sound quality of the panel speaker, achieving superior spatial sound, implementing multi-channel exciter speakers, and aligning the focus of sound with that of the screen a challenging feat in traditional LCDs. In this study introduces the application of this technology in automotive environments, enhancing the in-vehicle sound experience through the use of information devices. The proposed method utilizes the OLED panel speaker for delivering essential information to drivers, thereby ensuring more accurate voice transmission and enhancing sound quality in conjunction with the vehicle's door trim-mounted sound system. Additionally, this approach allows for a distinct and secure auditory experience both inside and outside the vehicle.
