摘要： An electronic view finder includes a display element that displays an image, and an eyepiece lens that is disposed on an eyepoint side of the display element and that is used for observing the image. The eyepiece lens consists of a first lens, a second lens having refractive power of a different sign from the first lens, and a third lens having positive refractive power in order from a display element side. Diopter is adjustable by moving at least one lens of the eyepiece lens. A television distortion of the image displayed by the display element varies depending on the diopter.

摘要： The present invention is a lightweight night vision device (NVD) sealed from environmental conditions, shielded from electromagnetic interference (EMI), and having mechanisms for easy adjustment and fixation of collimation and interpupillary distance. The NVD monocular housing is integrated with the eyepiece, image intensifier tube module, and objective, allowing collimation to be fixed via an optical alignment of the monocular housing to its eyepiece, tube module, and objective. Certain components from existing NVDs may be reused in assembling the present invention to provide cost savings.

摘要： A wearable display system includes an eyepiece stack having a world side and a user side opposite the world side. During use, a user positioned on the user side views displayed images delivered by the wearable display system via the eyepiece stack which augment the user's field of view of the user's environment. The system also includes an optical attenuator arranged on the world side of the of the eyepiece stack, the optical attenuator having a layer of a birefringent material having a plurality of domains each having a principal optic axis oriented in a corresponding direction different from the direction of other domains. Each domain of the optical attenuator reduces transmission of visible light incident on the optical attenuator for a corresponding different range of angles of incidence.

摘要： A display device including a display panel and an eyepiece is provided. An image realized by the display panel can be provided to a user by passing through the eyepiece. The display device can further include a front quarter-wave plate and a rear quarter-wave plate in order to increase the path of light traveling toward the eyepiece from the display panel. A barrier can be disposed between the front quarter-wave plate and the rear quarter-wave plate. The barrier can reflect or transmit the light traveling toward the eyepiece from the display panel on a region-by-region, so that the loss of light recognized by the user through the eyepiece can be minimized.

摘要： A display device including a display module and an eyepiece lens is provided. A user can view an image realized by the display module through the eyepiece lens. In the display play according to the present disclosure, a path of a light moving from the display module to the eyepiece lens may be increased by a half-mirror and a reflective polarizing plate which are located between the display module and the eyepiece lens. Thus, in the display device according to the present disclosure, the overall thickness may be decreased without degrading the quality of the image realized by the display module.
