Patent number: 11256102Abstract: An immersive headset device is provided that includes a display portion and a body portion. The display portion may include microdisplays having a compact size. The microdisplays may be movable (e.g., rotational) relative to the body portion and can be moved (e.g., rotated) between a flipped-up position and a flipped-down position. In some instances, when the microdisplays are flipped up, the headset provides an augmented reality (AR) mode to a user, and when the microdisplays are flipped down, the headset provide a virtual reality (VR) mode to the user. In certain implementations, the headset includes an electronics source module to provide power and/or signal to the microdisplays. The electronics source module can be attached to a rear of the body portion in order to provide advantageous weight distribution about the head of the user.Type: GrantFiled: January 17, 2020Date of Patent: February 22, 2022Assignee: eMagin CorporationInventors: Jerome T. Carollo, Amal Ghosh, John Chi-Liang Ho, Andrew Thomas Manning Rosen
