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.

Disclosed embodiments relate to a light-emitting assembly and a display device. In some embodiments, the light-emitting assembly includes a lamp bead a lamp bead mounting plate and a lamp bead shading face mask, the lamp bead shading face mask covering the lamp bead, and there is a distance between the lamp bead shading face mask and the lamp bead, at least two side faces of the lamp bead shading face mask including light emergence holes, wherein one side, facing the lamp bead mounting plate, of the lamp bead shading face mask is provided with a first reflecting surface; one side, facing the lamp bead shading face mask, of the lamp bead mounting plate is provided with a second reflecting surface; and light emitted by the lamp bead is reflected by the first reflecting surface and the second reflecting surface and then emitted out of each of the light emergence holes.

A solar powered vehicle topper unit and systems and methods for the same are provided. A solar energy harvesting device is electrically connected to an electronic display within a housing. The solar energy harvesting device is located above the housing. The solar energy harvesting device has a first footprint, and the housing has a second footprint which is smaller than the first footprint.

Display modules have a plurality of light emitting elements arranged in a predetermined pattern and providing a highly uniform visual effect. Methods are provided to support a plurality of flexible display modules in an adjustable curved arrangement. Alignment and complementary alignment features enable the alignment of adjacent display modules and the creation of large displays from a plurality of aligned display modules. Features to couple to and retain a support frame are provided. Flexible and durable weather resistance features are provided. A system of modular support frames works cooperatively with the display modules, adapting to different mounting environments, and thereby providing large modular displays with desirable properties.

Illustrative embodiments of the disclosure are generally directed to circuitous display systems methods which facilitate automated scheduling and uploading of advertising and/or other content to different display faces in a network or display circuit of billboard or other display faces and automatic circuitous, sequential or rotational presentation of the content among the display faces. An illustrative embodiment of the circuitous display systems may include at least a first display face and a second display face. At least one display control system may controllably interface with each of the first display face and the second display face. The at least one display control system may be configured to present content on the first display face and the second display face in an automatic circuitous, sequential or rotational pattern.

A supporting apparatus for suspending two displays includes: a base seat unit including a fixing bracket and a pillar that is connected to the fixing bracket; two suspending arms, each having a first end portion that is movably connected to the pillar unit such that each of the suspending arms is movable along the pillar, and a second end portion that is opposite to the first end portion; two slide track units respectively connected to the second end portions of the suspending arms; and two display-supporting bracket units movably connected to the slide track units for mounting the displays. Through operation of the suspending arms, the sliding track units and the display-supporting bracket units, the displays can be moved to juxtapose and contact each other.

A cable hanger includes: a base panel having opposed ends; a pair of arms, each of the arms attached to a respective end of the base panel and having a free end; a pair of locking projections, each of the locking projections attached to a respective free end of the arms; and a pair of gripping members, each gripping member attached to a respective arm, each gripping member having opposed ends, wherein one of the ends of each gripping member is fixed to the arms and the other of the ends of each gripping member is fixed to the arm or to the base panel. The arms and locking projections are configured to spread apart to enable insertion of a cable between the arms, wherein the gripping projections engage and grip the cable, and wherein the locking projections are configured to be inserted into the aperture of the supporting structure.

A LED billboard system that is adapted to mount to pre-existing or future billboard structures such that when the LED panels are switched on, the LED billboard can be illuminated from behind.

A billboard framework system may have a plurality of lateral adjusters adapted to be laterally adjustable on poles. The system may also have at least one frame support attached to some of the plurality of lateral adjusters where each of the frame supports may be co-planar with one another. The system may also have a generally rectangular-shaped frame structure connected to the frame supports where the frame structure is coplanar. The frame structure may have two side portions connecting an upper portion and a lower portion.
