Abstract: This application discloses an interaction method performed by a display device and the display device. A three-dimensional virtual object may be obtained; an optical signal of the virtual object is transmitted to a first region of a space and then projected from the first region into a second region of the space through the display device, so that an image of the virtual object is generated in the second region of the space that is outside the display device; when it is detected that a user performs a motion sensing operation on the image of the virtual object in the second region of the space, the virtual object is updated based on the motion sensing operation, to obtain an updated virtual object; and an optical signal of the updated virtual object is then used for generating an image of the updated virtual object in the second region of the space.

Abstract: The present disclosure relates to a virtual reality display device. The virtual reality display device includes: a main lens, a semi-reflective lens, a first display screen, a second display screen, a zoom assembly and an eye tracking camera. The main lens is arranged in front of the first display screen and perpendicular to a first direction. The semi-reflective lens is arranged between the main lens and the first display screen. The eye tracking camera points to an eyeball position. The second display screen faces the semi-reflective lens, and light emitted from the second display screen is reflected by the semi-reflective lens and then propagates along the first direction. The zoom assembly is arranged on a front side of the second display screen. The second display screen is configured to display an image based on an eyeball focus position detected by the eye tracking camera.

Abstract: A liquid crystal display (LCD) driving method includes: determining drive voltages of pixel units in a plurality of screen regions of an LCD based on an image frame to be displayed; outputting, for one of the plurality of screen regions, a first drive signal to a pixel unit in the screen region based on the determined drive voltage corresponding to the pixel unit, the first drive signal being used for controlling a liquid crystal molecule corresponding to the pixel unit in the screen region to rotate at the drive voltage; and outputting a second drive signal to a backlight source of the LCD when the first drive signal is output to the pixel unit in the screen region and a target duration is reached, the second drive signal being used for controlling a part of the backlight source corresponding to the screen region to be turned on.

Abstract: This application discloses a device for generating a holographic stereoscopic image. The device includes a body, a three-dimensional display, and a negative refractive index plate. The body includes a first cavity and a second cavity, a bending angle existing between a central axis of the first cavity and a central axis of the second cavity. A second end of the first cavity is in communication with a first end of the second cavity, an opening being formed by a second end of the second cavity on a side wall of the body. The three-dimensional display is arranged on the first end of the first cavity, and the negative refractive index plate is arranged between the second end of the first cavity and the first end of the second cavity. A display direction of the three-dimensional display faces the negative refractive index plate, and a refraction direction of the negative refractive index plate faces the opening.

Abstract: The invention is directed to a nanostructured composite material comprising a mixture of at least one metal particle such as iron and a carbon material from biomass such as D-glucose, D-glucosamine hydrochloride or ?-cyclodextrin. The invention is also directed to a composition comprising the composite material comprising the composite material and an inorganic salt, and a method for synthesizing the composite material comprising immersing the carbon material into a solution of metal ions, drying the impregnated carbon particle and subjecting the impregnated carbon particle to a carbothermal reduction process. The nanostructured composite material is useful as an oxygen scavenging layer in a multi-layer film which comprises the oxygen scavenging layer and an oxygen barrier layer that retards the permeation of oxygen from an external environment.
