A method to adjust the height of a display is provided. One terminal of the telescopic trolley is connected to a first surface of the display and is separated from the lower edge of the display by a first distance. The lower edge of the display is away from the ground by a second distance. The method includes: obtaining a first height value indicating a user's height, an eye height or a shoulder height, searching for a second height value corresponding to the first height value in the look-up table according to the first height value, calculating the sum of the first distance and the second distance, comparing the sum with the second height value to obtain a comparison result, and adjusting the length of the telescopic trolley according to the comparison result, so that the sum is equal to the second height value.

A three-dimensional display system includes a first display and a second display spaced apart from the first display having one or more light sources configured to emit light and to illuminate the first display, where the first display is at least partially transparent such that the second display is visible through the first display. The three-dimensional display system includes a special effect system disposed at least in part between the first display and the second display and is configured to be activated to cause a special effect to be visible through the first display. The three-dimensional display system includes a controller communicatively coupled to the first display, the second display, and the special effect system.

A display unit for a passage control device, having a housing that has a front side, a rear side and an encircling circumferential side connecting the front side and rear side to one another. A display surface is integrated in the front side of the housing. The housing has an optical signaling apparatus that consists of front and rear light bands that are able to be actuated by a computing unit of the passage control device. The front light strip is arranged between the front and circumferential sides and the rear light strip is arranged between the rear and circumferential sides such that the front light strip is visible in a plan view of the front side and the rear light strip is visible in a plan view of the rear side.

A flexible display screen system and method includes an article that has a flexible material configured to cover at least a portion of a person's anatomy or at least a portion of an object. At least one flexible display screen is secured on the flexible material. A computer system is configured to provide image information for controlling a display of images on the flexible display screen. The computer system is configured to control the display of images on the flexible display screen in response to the sensor signal. The sensor may sense flexing of the flexible display screen or flexible material. Alternatively or in addition, the flexible display screen or flexible material may be controlled to flex, in response to the images displayed on the flexible display screen.

A display unit includes a transparent or translucent layer with a display side and a rear side, with an opaque or semitransparent layer on the display side, containing a plurality of apertures, a plurality of illuminants which are present at, or at a distance from, the rear side of the transparent or translucent layer, at least partly embedded in the layer, wherein at least one illuminant is substantially behind one of the apertures in each case configured and designed to emit light in the direction of and through the aperture, a transparent or translucent lamination ply adjoining the opaque or semitransparent layer and covering the plurality of apertures, and a transparent or translucent protective layer adjoining this lamination ply. Also disclosed are a display apparatus and a traffic guidance system comprising such a display unit, and use of the display unit as a media energy façade or a daylight display.

A messaging apparatus for wearable items. The messaging apparatus may comprise a light source, at least one sensor to detect are event, and a controller to control the flashing of the light source in response to the detection of the event. The controlling of the flashing of the light source may generate at least one visible element that is visible to a viewer. Further, the light source may not be adapted in the form of the at least one visible element, but rather, the controlled flashing of the light source may be in the form of the at least one visible element.

An integrated lighting system to efficiently manage battery life with indoor and outdoor modes by charging a battery during the day, turning on lights at peak night hours, and protecting the battery from overvoltage/leakage. The system comprises circuitry operable to connect to the battery and the LED light sources, the circuitry comprising a solar cell, a timer circuit, and a protection circuit. The solar cell charges the battery during daylight hours. The timer circuit regulates time periods during the day to turn on the LED light source. The overcharge circuit prevents damage from possible overcharge/leakage.

A light-emitting sign comprising a light source for emitting light, in which the light-emitting sign may be thin (e.g., comparable to a conventional non-light-emitting sign) while creating a desired visual effect using the light emitted by the light source. This may be achieved, for example, by the light source being thin itself and/or by having an external device connected to the light-emitting sign and implementing certain functionalities (e.g., powering and/or controlling the light source).

Digital signage according to an embodiment of the present invention includes: a display unit; a human body sensing sensor unit; and a control unit which controls the operation of the digital signage, wherein the human body sensing sensor unit senses a motion of a human body and the distance between the human body and the digital signage, and the control unit can control so as to divide a frame buffer of content according to a predetermined set value, and to change an arbitrary pixel in a region of the divided frame buffer to black.

There is provided an information processing system. A recognition unit recognizes a user near a display device that displays information. An acquiring unit acquires information of an interest level with respect to each theme of the user who is recognized by the recognition unit. A display control unit controls the display device to highlight the information on the theme according to the interest level corresponding to the theme.
