With the technological improvements in the display industry, display panel manufacturers have changed the picture quality from simple high definition to augmented reality or virtual reality. In the previous research, the sound field implementation and sound quality improvement using organic light-emitting diode (OLED) flat panel was introduced. Recently, we have developed a technology for implementing sound in a drive even on a high-quality liquid crystal display. The LED panel has a multi-layer structure, and the backlight unit has a disadvantage of the wavelength transmission structure. In this study, we proposed a method to analyze LCD more effectively through previous studies. Also, we can play left channel and right channel like analysis 2 channel flat panel speakers with one panel. This flat panel speaker consists of direct drive actuator and diaphragm and is used as the outer glass layer of OLED and multilayer LCD. In the LCD panel, we configured the enclosure and adjusted the exciter for the output powers of the exciter were controlled to ensure. Furthermore, the vibration was transmitted to the last flat sheet. We also implemented a clear-sounding direct-drive exciter speaker flat panel display.
