Abstract

본 발명은 영상 미디어 기기의 가상화면을 구현하는 헤드 탑재형 디스플레이(HMD) 장치에 관한 것이다. 종래 장치는 종횡비 3:4의 가상화면만을 구현할 수 밖에 없었다. 본 발명은 장치의 크기를 크게 하지 않으면서도 종횡비 9:16의 와이드 가상화면을 구현할 수 있도록 하기 위하여 광원(1) 및 반사경(2)으로 이루어진 조명계와, 그 조명계의 빛을 선택적으로 투과시켜 화상을 형성하는 액정디스플레이 소자(3)와, 상기 액정디스플레이 소자(3)의 화상을 확대하여 확대된 허상으로 가상화면을 구현하는 가상화면 구현수단을 구비한 헤드 탑재형 디스플레이 장치를 구성함에 있어서, 입력된 비디오 신호를 디지탈 정보로 변환시킨후 임의의 비율을 갖는 2개의 화면정보로 분할하는 화면정보 분할수단과, 상기 분할된 화면정보를 각기 입력하는 2개의 기억수단과, 상기 기억수단의 화면정보를 부분적으로 중첩시켜 임의의 비율을 갖는 한 화면으로 디스플레이 되게 하는 화면 중첩수단을 구비하여, 종횡비 9:16의 와이드 가상화면을 구현하도록 구성한 것이다.The present invention relates to a head mounted display (HMD) device for implementing a virtual screen of a video media device. Conventional devices have only to implement a virtual screen with an aspect ratio of 3: 4. The invention provides an illumination system comprising a light source (1) and a reflector (2), and selectively transmits the light of the illumination system so as to realize a wide virtual screen with an aspect ratio of 9:16 without increasing the size of the device. In constructing a head-mounted display device having a liquid crystal display element 3 to be formed and a virtual screen implementation means for enlarging an image of the liquid crystal display element 3 to implement a virtual screen with an enlarged virtual image, Screen information dividing means for converting a video signal into digital information and dividing it into two screen information having an arbitrary ratio, two storage means for respectively inputting the divided screen information, and screen information of the storage means partially. Wide virtualization with an aspect ratio of 9:16, provided with screen superimposing means for superimposing the screen to be displayed on one screen having an arbitrary ratio. To be configured to implement.
