A display apparatus includes a frame case to support four sides of a display panel. The frame case is formed by bending a bar-shaped member made of a metal into a rectangular ring shape. Opposite ends of the bar-shaped member facing each other are covered by a cover member, which prevents quality degradation of the appearance of the display.

A light guide module includes a light guide element and a light source. The light guide element includes a first light guide layer and a second light guide layer. The second light guide layer is disposed on the first light guide layer. The refractive index of the first light guide layer is greater than the refractive index of the second light guide layer. The light source is disposed in the first light guide layer.

A backlight module and a display device are provided. The backlight module includes a frame body having a frame surface and a connecting part connected to the frame surface; a reflection sheet disposed on the frame surface; a light guide plate disposed on the reflection sheet; an optical film group disposed on the light guide plate, the optical film group includes a light enhancement sheet, and a top of the connecting part is connected to the light enhancement sheet through a plastic frame; a light-shielding sheet disposed on the optical film group; a blind hole, the blind hole penetrates from the frame surface to the light-shielding sheet, and the connecting part is disposed at a periphery of the blind hole; and an opaque glue layer disposed between the plastic frame and the light enhancement sheet.

An optical combiner lens includes a lens, a protective enclosure embedded in the lens, and a lightguide contained in the protective enclosure. First spacers are arranged between a first surface of the lightguide and the protective enclosure to provide a first gap between the lightguide and the lens. Second spacers are arranged between a second surface of the lightguide and the protective enclosure to provide a second gap between the lightguide and the lens. A wearable heads-up display including the optical combiner lens is disclosed.

A backlight module and a display device are provided. The backlight module has a plastic frame and a light guide plate located in the plastic frame. Convex portions and groove portions aligned to the convex portions are formed on the plastic frame to form an elastic structure. One of the convex portions is configured to contact with a sidewall of the light guide plate, and one of the convex portions is offset toward a side of one of the groove portions by being pressed by the light guide plate, thereby deforming one of the groove portions, so that the elastic structure and the light guide plate form an interference fit. Therefore, the light guide plate is fixed in the plastic frame without offset.

According to one embodiment, a display device includes a display panel, a case including a bottom plate opposing a rear surface of the display panel and a side plate stand on the bottom plate and attached to the display panel, a flexible wiring board, one end of which is joined to the display panel, curved around the side plate toward the bottom plate to oppose the bottom plate while, and an adhesive filled between the flexible wiring board and the side plate of the case or between the flexible wiring board and both of the side plate and the bottom plate, to adhere the flexible wiring board onto an outer surface of the case and hold the flexible wiring board in a curved state.

An imaging apparatus for conveying a virtual image superimposed within a view of an ambient environment has a wave-guide having first and second surfaces. An in-coupling diffractive optic on one of the planar surfaces is disposed to direct image-bearing light beams into the waveguide. An out-coupling diffractive optic on one of the planar surfaces of the waveguide is disposed to direct the image-bearing light beams from the waveguide toward a viewer eyebox. An outer cover protects as least part of the waveguide from undesirable environmental influences of an ambient environment while supporting views of the ambient environment from the eyebox. A circular polarizer interposed between waveguide and the outer cover blocks the return of stray light into the waveguide.

A backlight module and a display device are provided. The backlight module has a plastic frame and a light guide plate located in the plastic frame. Convex portions and groove portions aligned to the convex portions are formed on the plastic frame to form an elastic structure. One of the convex portions is configured to contact with a sidewall of the light guide plate, and one of the convex portions is offset toward a side of one of the groove portions by being pressed by the light guide plate, thereby deforming one of the groove portions, so that the elastic structure and the light guide plate form an interference fit. Therefore, the light guide plate is fixed in the plastic frame without offset.

A display device according to the present disclosure can include a display panel, a backlight assembly providing light toward the display panel, a set cover including a rear cover part and a side cover part, wherein the rear cover part covers a rear surface of the backlight assembly and the side cover part extending from the rear cover part covers a side surface of the backlight assembly, and a guide panel coupled to the set cover and supporting edges of the display panel. The set cover can be composed of plastic, and the rear cover part and the side cover part can have an integrally formed shape and can be exposed to outside.

A display apparatus includes: an indicator configured to display an image on a display surface of the indicator; a cover plate configured to stick on the display surface of the indicator with a transparent adhesive, and including a light transmitting section to enable the display surface to be visible; an optical device arranged behind the indicator through a gap to the indicator, and configured to supply a light to a back surface of the indicator for a display on the indicator; a first support configured to support the optical device; a second support configured to support the cover plate; and a cushioning material provided at the gap and be in contact with both of the indicator and the optical device.
