또한, 본 발명의 실시예에 따른 체적형 디스플레이 시스템은, 라이트 필드(Light Field) 방식을 채택하여 깊이감을 극대화시킨다.In addition, the volumetric display system according to the embodiment of the present invention maximizes the depth by adopting a light field method.
본 발명의 실시예에 따른 체적형 디스플레이 시스템의 외관에는, 도 2에 도시된 바와 같이, 양면 LED 매트릭스 패널(110), 진공 케이스(120) 및 모터(130)가 구비된다.The exterior of the volumetric display system according to the embodiment of the present invention, as shown in Figure 2, is provided with a double-sided LED matrix panel 110, a vacuum case 120 and a motor 130.
양면 LED 매트릭스 패널(110)은, 도 3에 도시된 바와 같이, 2개의 LED 매트릭스 패널들(111, 112)을 후면 끼리 대향하도록 부착한 디스플레이 패널이다. 이에 따라, LED 매트릭스 패널-1(111)과 LED 매트릭스 패널-2(112)는 서로의 반대면에 콘텐츠를 표시하게 된다.As shown in FIG. 3, the double-sided LED matrix panel 110 is a display panel in which two LED matrix panels 111 and 112 are attached to face each other.
