아이스링크 빙판 내부 LED디스플레이 결빙 구조 및 영상 최적화에 관한 연구

In this paper, we investigated the structure of ice for optimized image mapping after installing LED display device in the ice. The LED display device installed inside the ice transmits the image to the outside of the ice sheet, while the projector above the ice reflects the image from the ice surface. The core part that affects the LED display and projector image inside the ice structure is the scattering layer. The light transmittance was measured by the scattering layer application frequency, and the relative luminance ratio was calculated by measuring the LED display transmission luminance and the projector reflection luminance. Then, the mapping characteristics that overlapped the LED display image and the projector image were observed and the optimum image mapping condition was confirmed. Through this study, it was confirmed that the larger the scattering layer concentration, the smaller the difference between the LED display luminance and the projector luminance, and the better the mapping image can be obtained.
