A study on the characteristics of electroencephalography (EEG) by listening location of OLED flat TV speaker

초록

Along with the development in OLED TV panel manufacturing technology, the thickness of the panel is thinned, and the durability is also improved. It is also possible to generate sound by directly driving the panel. In this study, we have analyzed the acoustic characteristics of a directly driving the OLED panel speakers, using electroencephalography (EEG), in addition study the advantages of direct driving sound. For the experiment, we found that it is important that the two focal points coincide with each other through the EEG analysis when the focus of the screen and the focus of the sound are changed by adjusting the sound generated by the position in the OLED flat panel TV speaker. OLED TV with direct drive speakers has a basic effect of matching the positions of the screen and sound. This is because the direction of the sound and the direction of the screen coincide with the viewers of the TV, so that the stress is less and the viewing is comfortable compared to the conventional TV. The acoustic characteristics of proposed OLED speakers are high in resolution. And the sound quality is better than ordinary TVs, because of direct transferred sound instead of listening to reflections or difference sound sources compared with. ?
