A water treatment system having a base assembly and a treatment assembly. The treatment assembly of the system may be configured to filter particulates from water. The base assembly may include a UV reactor operable to disinfect water for consumption.

An animated poster system including a simulation panel, an image server having appropriately processed media, and a projector enable a moving image to appear on a textured surface of the panel with no detectable projection devices. The simulation panel includes a portion that, when illuminated by the projector with the media, appears to be paper that is wrinkled, torn, and/or pasted to the wall, and includes graphics that also appear to be printed but include moving images. The animated poster system can produce a convincing illusion of an animated poster, even at close observing distances.

A display device includes first light emitting devices arranged in a line in a protective member, second light emitting devices parallel to and alternately arranged with the first light emitting devices, and optical member supporters in the protective member between the first and second light emitting devices. Each optical member supporter is positioned at a center of a parallelogram defined by two adjacent first light emitting devices and two adjacent second light emitting devices, and each transparent optical member supporter includes a first surface that faces one of the first light emitting devices and a second surface opposite the first surface that faces one of the second light emitting devices. Each optical member supporter includes a plate portion having the first and second surfaces, and a hook portion that extends through the protective member. A width of the plate portion decreases with increasing distance from the hook portion.

According to embodiments of the present disclosure, an apparatus for adjusting the luminance of a screen of a spliced display device may include: an adjustment module configured to control rotation of a light-emitting unit within a backlight module in the spliced display device within a range; a collection module configured to collect a plurality of pieces of luminance information of a spliced screen of the spliced display device when the light-emitting unit is rotated at various angles; and a processing module configured to calculate a ratio between a minimum luminance value and a maximum luminance value for each piece of the luminance information, determine a maximum value among a plurality of the ratios and a specific angle of rotation of the light-emitting unit corresponding to the luminance information having the maximum value, and rotate the light-emitting unit at the specific angle of rotation by controlling the adjustment module.

An electronic display device is provided. The electronic display device includes an electronic display panel and a rear chassis assembly. The rear chassis assembly includes a bottom wall, a first and a second side wall, and a first and a second sheet. The first and the second side walls are respectively disposed at two opposite edges of the bottom wall. The electronic display panel is positioned in an accommodation space defined by the first side wall, the second side wall, and the bottom wall. The first and second sheets are respectively fixed on the first and second side walls. The curvature of the first sheet corresponds to the curvature of the first side wall, and the curvature of the second sheet corresponds to the curvature of the second side wall.

An invisible, light-transmissive display system with a light resistant material is provided. Substantially invisible, tapered, light-transmissive holes are penetrated in a light transmissive pattern through at least a portion of the light resistant material using a laser beam having a focal width less than the smallest diameter of the tapered holes.
