An electrically controlled spectacle includes a spectacle frame and optoelectronic lenses housed in the frame. The lenses include a left lens and a right lens, each of the optoelectrical lenses having a plurality of states, wherein the state of the left lens is independent of the state of the right lens. The electrically controlled spectacle also includes a control unit housed in the frame, the control unit being adapted to control the state of each of the lenses independently.

A wearable display apparatus is provided. The wearable display apparatus according to an embodiment includes a display, a sensor configured to detect motion of the wearable display apparatus and output motion data corresponding to the motion of the wearable display apparatus, the output motion data including a non-zero roll component, and a processor configured to obtain three-dimensional (3D) image data, obtain the output motion data from the sensor, generate a first virtual reality (VR) 3D image based on the obtained 3D image data and a portion of the obtained motion data excluding the non-zero roll component, and control the display to display the generated first VR 3D image.

A novel light source for a 3D display system includes a plurality of left eye light emitters and a plurality of right eye light emitters. The left eye emitters include a broad spectral distribution emitter and an overlapping narrow spectral distribution emitter in each of the blue, green, and red color bands. Similarly, the right eye emitters include a broad spectral distribution emitter and an overlapping narrow spectral distribution emitter in each of the blue, green, and red color bands. The combined spectral distributions of each of the broad and narrow emitters provide a primary light for each color and for each eye that has a desirable spectral shape, including wide bandwidth and short tail(s). The invention thus minimizes cross-talk and speckling in left- and right-eye images of 3D display systems.

A novel projection system includes first and second light sources (e.g., sets of lasers), a spatial light modulator (SLM) that receives light from the first light source, and a beam steering device that receives light from the second light source and steers the light to highlight regions of the SLM. The SLM then modulates the light from both light sources to generate a highlighted imaging beam which can then be projected on a viewing surface. The highlighted imaging beam can represent a highlighted 2D image or a highlighted left- or right-eye view of a 3D image. The projection system thus improves peak brightness in the displayed highlighted images without incorporating a separate highlight projector or other expensive equipment. Methods for highlighting projected images are also described.

A stereoscopic image projection device and stereoscopic display glasses include a light source system for sequentially generating a first broad spectrum light and a second broad spectrum light; a light splitter for splitting the first broad spectrum light into a first wavelength light and a second wavelength light, each having different wavelengths, and splitting the second broad spectrum light into a third wavelength light and a fourth wavelength light, each having different wavelengths; and a controller for simultaneously controlling the first wavelength light to display a corresponding color in a left-eye image and the second wavelength light to display a corresponding color in a right-eye image, and simultaneously controlling the third wavelength light to display a corresponding color in the left-eye image and the fourth wavelength light to display a corresponding color in the right-eye image. At the same time, the left eye of a viewer can see the first wavelength light or the third wavelength light, and the right eye thereof can see the second wavelength light or the fourth wavelength light, such that the left and right eyes of the viewer simultaneously receive light rays, thus relieving fatigue to the eyes.
