| 20150102982 | HEAD MOUNTED DISPLAY - According to one embodiment, a head mounted display includes a holder, a projector, an optical part, a weight, a detector, a first calculator, and a movement part. The holder includes a frame, a first temple, and a second temple. The first temple and the second temple are respectively connected to each end part of the frame. The projector is provided on the first temple. The projector emits light. The optical part is provided on the frame. The optical part reflects at least part of the light emitted from the projector. The weight is provided on opposite side of the projector. The detector detects tilt of the holder. The first calculator calculates an optimal position of the weight based on the tilt of the holder. The movement part changes the position of the weight according to the optimal position. | 04-16-2015 |
| 20150116190 | DISPLAY DEVICE - According to one embodiment, a display device includes a light emitting unit, a reflective unit, a sensor, and a controller. The light source emits light including an image information relating to operation to be performed by an operator. The reflector reflects at least a part of the light emitted from the light source toward an eye of the operator and transmits at least a part of light to be incident on the eye when the reflector is disposed in front of the eye of the operator. The sensor senses a working state of the operator. The controller controls the light source based on the working state in a manner that a luminance of the light emitted from the light source is reduced when the working state indicates that the operator is at work. | 04-30-2015 |
| 20150116357 | DISPLAY DEVICE - According to one embodiment, a display device includes a light emitter, a reflector, a virtual image position controller, and a holder. The light emitter emits light flux including an image. The reflector is in front of an eye of a viewer. The reflector is partially reflective and partially transparent and reflects the light flux toward the eye and form a virtual image. The virtual image position controller controls a position of the virtual image. The holder holds the reflector. The virtual image position controller sets the position of the virtual image to a first position on a line connecting the eye and a background object in front of the eye and subsequently moves the position of the virtual image to a second position on the line that lies closer to the reflector than the first position. | 04-30-2015 |
| 20150205133 | DISPLAY DEVICE - According to one embodiment, a display device includes an image displayer that emits light including image information, a projector, a light condenser that projects the light, and a light controller. The light condenser is provided between the image displayer and the projector in an optical path of the light, and condenses the light. The light controller is provided between the light condenser and the projector in the optical path, and has a first surface. The light controller implements a first operation causing a first portion of the condensed light incident on a first region of the first surface to travel toward the projector and a second operation causing a second portion of the condensed light incident on a second region of the first surface to travel toward the projector. The first region has a configuration or a surface area different from the second region. | 07-23-2015 |
| 20150212577 | DISPLAY DEVICE AND GAZE ESTIMATING DEVICE - According to one embodiment, a display device includes an imager and an image displayer. The imager images a first image of a first state of an eyelid of a viewer. The image displayer includes a light emitter and an optical unit. The light emitter emits light including image information. The optical unit includes a combiner. The light is incident on the optical unit. The combiner causes at least a portion of the light to be incident on an eyeball of the viewer. The image displayer modifies an incident direction of the portion of the light on the eyeball based on the first image imaged by the imager. | 07-30-2015 |
| 20150338654 | DISPLAY - According to one embodiment, a display includes a projector, a first optical unit, and a second optical unit. The projector emits a first light including image information. The first optical unit transmits at least a portion of a second light. The second optical unit reflects at least a portion of the first light and transmits at least a portion of the second light. A light reflectance of the first optical unit is lower than a light reflectance of the second optical unit, and a light absorptance of the first optical unit is higher than a light absorptance of the second optical unit. | 11-26-2015 |
| 20150338657 | DISPLAY DEVICE - A display device includes a first optical part that reflects at least part of incident light and a projection part that projects image light including the image information. The first optical part includes a first base, a reflective layer, a second base, and an intermediate layer. The refractive index of the first base, the refractive index of the second base, and the refractive index the intermediate layer are about the same value. | 11-26-2015 |
| 20150338662 | DISPLAY DEVICE - According to one embodiment, a display device includes a position controller, a projection unit, and a reflector. The projection unit emits light including image information. The projection unit is held by a holder. The position controller is interposed between the holder and the projection unit. The reflector reflects at least a portion of the light emitted from the projection unit. The reflector is held by the holder. A position of the reflector with respect to the holder is fixed. A relative arrangement of the projection unit and the reflector is changeable by the position controller. | 11-26-2015 |
