A three-dimensional display device includes a display panel that displays a parallax image, an optical panel including a plurality of less-transmissive portions and a plurality of transmissive portions repeatedly arranged alternately in a parallax direction, and a controller that controls the display panel. Each of the plurality of transmissive portions has a first width in the parallax direction greater than a second width of each of the plurality of less-transmissive portions in the parallax direction. The controller causes the display panel to display a black image in a binocular viewable area on the display panel viewable to two eyes of a user to allow parallax separation of the parallax image.

A three-dimensional display device includes a display panel, a parallax barrier, an acquisition section, a memory, and a controller. The display panel is configured to display a parallax image and emit image light corresponding to the parallax image. The parallax barrier includes a surface configured to define a direction of image light. The acquisition section is configured to acquire positional data indicating eye positions from a detection device which is configured to detect eye positions based on photographed images which are acquired from a camera which is configured to image user's eyes. The memory is configured to store the positional data which are acquired by the acquisition section. The controller is configured to output predicted eye positions based on the positional data stored in the memory, and cause the display panel to display the parallax image, based on the predicted eye positions. The controller is configured to generate a left-eye image and a right-eye image based on a first predicted eye position, and combine the left-eye image and the right-eye image into a parallax image based on a second predicted eye position, which is different from the first predicted eye position.

A three-dimensional display device includes a display panel, a controller, and a communication unit. The display panel is configured to display an image. An optical element is configured to define a propagation direction of image light emitted from the display panel. The communication unit is configured to receive a captured image of first eye and second eye different from the first eye, of a user. The controller causes the display panel to display a calibration image. The controller is configured so that, based on cornea images of different parts of the calibration image in the captured image that are viewed with the first eye and the second eye of the user, respectively, a parallax image is displayed on the display panel.

Display methods and apparatus are described. In some embodiments, to generate an image, light is selectively emitted from one or more light-emitting elements (such as a μLEDs) in a light-emitting layer. The emitted light from each element is collimated using, for example, an array of microlenses having small apertures. Each beam of collimated light is split by a first diffractive grating into a first generation of child beams, and the first generation of child beams is split by a second diffractive grating into a second generation of child beams. Beams in the second generation of child beams that are not parallel to the original beam of collimated light may be blocked by a spatial light modulator (e.g. an LCD panel). The un-blocked beams operate in some respects as if they had been generated using optics with an aperture larger than the apertures of the microlenses.

A stereoscopic three-dimensional display and manufacturing method thereof includes a three-dimensional display and a depth sensor. The three-dimensional display includes a three-dimensional display module and a parallax optical module that corresponds to a plurality of first depth display portions and a plurality of second depth display portions and a first parallax optical portion and a second parallax optical portion. The depth sensor is electrically connected to the stereoscopic display module, and detects the distance between the user and the stereoscopic display, and selects whether all of the first depth display parts jointly output the first parallax image, or all of the second depth display parts jointly output the second parallax image, so that the user can view the stereoscopic imaging through the first parallax optical unit or the second parallax optical unit at different positions.
