Field of view (FOV) and resolution are very important parameters for head-mounted displays (HMD). However, so-called "resolution/field-of-view invariant" prevents single-channel HMD from achieving both high resolution and wide FOV. This limitation can be effectively broken by the tiled method. A binocular optical-tiled HMD with four spherical lenses that have been cut precisely is designed. Each eye includes two channels. For an eyepiece consisting of two channels, the horizontal FOV is 111.4° and the maximum vertical FOV is 90°. Three 6 inch (15.24 cm) liquid crystal displays with resolution of 1920 pixel×1080 pixel are used in this prototype as image source. The monocular angle resolution reaches 3.85 arcmin. 3D printing is also used to make the external structure of the HMD prototype. Key issues in the tiled system, such as exit pupil and exit pupil distance, are analyzed in detail. Based on these discussions, the intensity distribution of the human eye retina is simulated in LightTools. In addition, according to the distorted data of the lens design, the distorted image after processing is obtained. The image display experiment is performed on the prototype, and the results verify the feasibility of the proposed method.
