Abstract

In this study, we have researched for a high-efficiency display with low power, less complicated configuration, and more attractive features than using conventional displays (CRT, LCD, LED, etc.) by manufacturing a propeller display using the POV(Persistence of Vision) phenomenon. After setting the reference point using the Hall sensor, the channel recognition signal and voice recognition signal are transmitted to the display using Bluetooth through the mobile phone application created based on the App program, and the display performs different operations according to the commanded Bluetooth signal. Finally, it was confirmed that the desired information is expressed on the display screen at a motor speed of 1,030 rpm.

본 연구에서는 POV(Persistence of Vision) 현상을 활용한 프로펠러 디스플레이를 제작하여 기존 디스플레이(CRT, LCD, LED 등)를 이용하는 것보다 저전력, 간단한 구성, 더 매력 있는 생김새를 가지는 고효율 디스플레이의 동작 특성을 연구하였다. Hall 센서를 사용하여 기준점을 설정한 후 앱 프로그램을 기반으로 제작한 핸드폰 애플리케이션을 통해 채널 인식 신호 및 음성인식 신호를 Bluetooth를 사용하여 디스플레이에 표시하고 전달받은 동작 명령에 따라 명령을 수행하도록 디스플레이를 설계 제작하였다. 실험 결과, 모터 속도 1,030rpm에서 원하는 정보가 디스플레이 화면상에 최적으로 표현되는 동작 특성을 확인하였다.
