A closure for an apparatus comprises: a plurality of light sources; a lightguide to distribute light from the plurality of light sources, the lightguide having a first primary surface opposite a second primary surface, wherein the first primary surface has a first surface treatment, and wherein light emitted from the lightguide indicates a status of the apparatus; and a frame supporting the plurality of light sources and the lightguide for selective movement of the closure vertically or horizontally relative to the apparatus.

A display apparatus includes a light source, a display panel, a light guide member, and an optical member. The light source is configured to generate light. The display panel is configured to display an image. The light guide member includes at least one surface adjacent to the light source. The optical member is between the light guide member and the display panel. The optical member includes a low refractive layer, a first cover layer, and a light conversion layer. The low refractive layer is on a light output surface of the light guide member and includes side surfaces. The first cover layer is on the low refractive layer and surrounds at least a portion of the side surfaces of the low refractive layer. The light conversion layer is on the first cover layer and is configured to covert a wavelength band of incident light.

A portable lighting device including a shell, at least one luminous element, a lens component, a battery compartment, positive and negative terminals, at least one indicator mark disposed on the battery compartment, and light-transmitting channels is provided. The battery compartment is made of transparent and fluorescent materials. The indicator mark is used for indicating the positive or negative terminals. The light-transmitting channels allow the light emitted by the luminous element to irradiate and stimulate the battery compartment to emit light and exhibit an afterglow. Thus, by using the light from the battery compartment to illuminate the indication mark, the user can accurately determine the positive and negative terminals in the battery compartment in a dark environment, which is convenient to replace batteries or battery pack.

The present disclosure includes a first optical member (light-guiding member) and a second optical member (light-guiding member) that are included in a first display device and a second display device configured to display images corresponding to left and right eyes and are configured to guide the images, a central member serving as a coupling member configured to couple these light-guiding members, and a protruding portion provided on the central member and extending in a lateral direction (±X direction) in which these light-guiding members are aligned.

The disclosure relates to the technical field of liquid crystal display, and discloses a liquid crystal display module backlight structure which includes a light blocking tape, a FPC strip, rubber-iron layer, a reflective sheet, a light enhancement prismatic lens, a light guide plate, and a matt film layer, a first end of the matt film layer overlaps the FPC light strip and a second end overlaps the light enhancement prismatic lens; the first end is bonded to the light blocking tape and the second end is positioned between the light enhancement prismatic lens and the light guide plate.

A closure for an apparatus comprises: a plurality of light sources; a lightguide to distribute light from the plurality of light sources, the lightguide having a first primary surface opposite a second primary surface, wherein the first primary surface has a first surface treatment, and wherein light emitted from the lightguide indicates a status of the apparatus; and a frame supporting the plurality of light sources and the lightguide for selective movement of the closure vertically or horizontally relative to the apparatus.
