HMD, similar to PMD, can be divided into monocular and binocular, and the monocular is composed of an optical system separately for each eye, and a single optical system is composed of one eye. It is a way to do only, binocular expression is to configure the system so that the displayed image corresponding to each eye is complemented in both eyes.

In addition, the binocular display method can be divided into a stereo (stereo) method and a bi-ocular (bi-ocular) method.

The biocula method refers to the case where the images corresponding to the left and right eyes are the same, and the stereo method makes the depths by matching the same stores corresponding to the eyes with the left and right eyes corresponding to each image corresponding to the left and right eyes slightly different. In this way, a 3D image can be viewed.

CRT (Cathode Ray Tube) and flat panel display (mainly Liquid Crystal Display) have been used as the display elements of HMD devices, and flat panel displays are mainly used due to the volume, weight, and size, which are disadvantages of CRT.
