The support end is supported by the support frame and the load-bearing end is connected to the first end. The load-bearing pin is located between the optical film and the optical plate and the optical film is held up by the load-bearing pin so that the direction of extension of the optical film is changed.

A joint layout is provided for the firm bonding of components by means of a light-activated joining agent. A light guide element is arranged at least in sections in a joint gap between the components. The light guide element is embedded into the joining agent in the joint gap, and light for activating the joining agent can be outcoupled from the light guide element in the joint gap. In this context, at least one spacer is arranged in the joint gap between the light guide element and at least one of the components.

A planar illumination apparatus according to an embodiment includes a plurality of light sources, a light guide plate, a wiring substrate, a light diffusion sheet, a fixing member and an optical sheet. The light guide plate has a light entrance end surface and two main surfaces and emits, from at least one of the two main surfaces, the light entering the light entrance end surface. The wiring substrate extends so as to cover the light entrance end surface. The light diffusion sheet is arranged in a direction perpendicular to the main surfaces, one end portion of the light diffusion. sheet running on the wiring substrate. The fixing member is arranged to cover the light diffusion sheet. The optical sheet is arranged between the light diffusion sheet and the fixing member. The light diffusion sheet includes a notch formed from the one end portion.

A liquid crystal module and a display device are provided. The liquid crystal module includes a liquid crystal panel, a bottom frame and a first frame. The first edge of the liquid crystal panel is in an open region surrounded by the bottom plate, the first side plate and the second side plate of the bottom frame. At least one selected from a group consisting of the second edge, third edge and fourth edge of the liquid crystal panel is in an open region surrounded by the first frame body, the second frame body and the third frame body, and in a direction perpendicular to the plate surface of the liquid crystal panel, the first frame and the liquid crystal panel are movably arranged with respect to each other.

An optical film is disclosed. The optical film is divided into a main body and two extending portions arranged along a second direction by two imaginary lines which are extended along a first direction and parallel to each other, wherein the second direction is substantially perpendicular to the first direction. The main body is located between the two extending portions. Each of the extending portions has an abutting edge. A first length W0 of the main body along the first direction is greater than a second length W1 of the abutting edge along the first direction.

A backplate and a display panel are disclosed. The backplate includes a first transverse edge portion, a second transverse edge portion disposed opposite to the first transverse edge portion, a first longitudinal edge portion, and a second longitudinal edge portion disposed opposite to the first longitudinal edge portion. The first longitudinal edge portion is connected to the first transverse edge portion and the second transverse edge portion, the second longitudinal edge portion is connected to the first transverse edge portion and the second transverse edge portion, and an accommodation chamber is defined by the first transverse edge portion, the second transverse edge portion, the first longitudinal edge portion, and the second longitudinal edge portion.

A fastening device, a method of operating the fastening device, and a display panel are provided. The fastening device includes a diffuser and a limiter, wherein the limiter includes a deformation portion and a non-deformation portion disposed opposite to each other to enclose a receiving portion, and the diffuser is configured to be received in the receiving portion, so as to adjust a deformation size of the deformation portion by movement of the diffuser.

A display device includes a backlight assembly and a display panel which displays an image. The backlight assembly includes a light emitting unit which generates light, and an optical member which adjusts a path of the light incident thereto and outputs the light toward the display panel. The optical member includes a first base film to which the light is incident, a second base film closer to the display panel than the first base film and for which are defined first and second areas alternately disposed, a first optical pattern between the first and second base films at the first area, where the first optical pattern refracts therein the light incident to the first base film, and a second optical pattern between the first and second base films at the second area, where the second optical pattern scatters the light incident to the first base film.

The present invention provides an optical purification layer, an edge-lit backlight module, and a polarizer. The material of the optical purification layer includes an organic absorbing dye for absorbing cyan light and yellow orange light having a wavelength range of 560-610 nm. The edge-lit backlight module includes a back plate, a reflector, a light guide plate, an edge light source, and an optical film module stacked, wherein the optical purification layer is provided between the edge light source and the light guide plate, or the optical purification layer is further provided between the light guide plate and the diffuse reflection layer, or the light guide plate includes a material of the optical purification layer.

A liquid crystal module and a display device are provided. The liquid crystal module includes a liquid crystal panel, a bottom frame and a first frame. The first edge of the liquid crystal panel is in an open region surrounded by the bottom plate, the first side plate and the second side plate of the bottom frame.
