The invention provides an LCD module and an LCD device. The LCD module includes a backlight module, and an LCD panel arranged above the backlight module; the backlight module includes a backplane, and an optical film(s); a side wall(s) of the backplane is provided with a limit structure which is integrated with the backplane, and the edge of the LCD panel is butted on the limit structure. In the invention, because the corresponding limit structure is arranged on the side wall of the backplane to limit the degree of freedom of the LCD panel in the plane direction of the panel surface, the rubber frame is not required to limit the degree of freedom of the LCD panel in the plane direction of the panel surface; thus, the structure of the rubber frame is simplified, the material of the rubber frame is saved, and the processing cost is saved.

A backlight module and a liquid crystal display are provided. The backlight module includes a light guide plate, a source, a first back plate and a second back plate. The first back plate includes a first main body and a first bending portion. The second back plate includes a second main body and a second bending portion. The first main body is slidably connected to the second main body. The light guide plate is fixedly connected to the first main body. A light-emitting surface of the light source is against a light incidence surface of the light guide plate, and another surface of the light guide plate is close to an inner side of the second bending portion. When the light guide plate expands with heat, the expanded light guide plate pushes the second bending portion to make the second back plate slide relative to the first back plate.

The backplane for a liquid crystal display (LCD) device includes side walls, and the backplane at least includes two backplane units. A horizontal moving guide device is arranged between the adjacent backplane units, and an elastic device which enables the two backplane units to relatively elastically expand and contract horizontally is further arranged between the adjacent backplane units. The backplane of the LCD device of the present disclosure is designed to be able to elastically expand and contract in a direction perpendicular to a light emitting diode (LED) lightbar. When a light guide panel (LGP) in the backplane expands after absorbing heat, the backplane is extended by a pushing force, and heat expansion quantity of the LGP is directly absorbed. When the LGP is contracted because of temperature drop, the backplane is shortened under action of the elastic device, and a light coupling distance between the LGP and the LED lightbar is always kept constant.

A backlight module is disclosed, comprising a light guide plate and light sources, where the light guide plate comprises lateral incident faces, an exit face that joins the lateral incident faces, and an underside that corresponds to the exit face. The light sources each comprises an emitting surface, is disposed near one side of one lateral incident face of the light guide plate, and corresponds to the lateral incident face of the light guide plate with the emitting surface. The backlight module further comprises diffusion strips, where the diffusion strips each is disposed in between one lateral incident face of the light guide plate and the emitting surface of the light source, and the light rays emitted from the emitting surface of the light source pass the diffusion strip and diffuse into the light guide plate. This invention further discloses a liquid crystal display.

The invention provides an optical film for an LCD device and an LCD device. The optical film includes a display area in a middle part and a non-display area in an edge part; the non-display area is provided with a light shading layer. The inventor finds that the non-display area of the optical film just covers a surface of the middle frame; thus, the light shading layer is directly arranged in the non-display area of the optical film, to prevent the middle frame from leaking light in a joining position. In addition, the invention uses the existing material to achieve the light shading capability of the middle frame, thereby having the advantages of simplicity, practicality, and low cost.

The invention provides a middle frame for an LCD module and an LCD device. The middle frame for an LCD module includes a plurality of segmented members constituting the middle frame, and further includes a corner member which is arranged on a corner of the middle frame. The corner member is provided with a light blocking wall which is used for blocking a gap in a connecting position between the corner member and the segmented member. In the invention, because the LCD module is divided into a plurality of segmented members, the middle frame can be obtained by only making the same section, and cutting the section to form the segmented members. Thus, the production cost of the middle frame can be saved, and the segmented members of different lengths can be matched to make middle frames of different sizes, thereby saving the cost of moulds. Moreover, the corners of the middle frame are respectively provided with the corner members used for connecting the segmented members, and the corner members are provided with the light blocking wall used for blocking the gap in the connecting position between the segmented member and the corner member. Thus, the corner of the middle frame is prevented from generating a light leakage because of the gap in the connecting position.

The invention relates to the field of LCDs, and more particularly to an LCD device and a backlight module. The LCD device includes a middle frame, a backplane, and an LCD panel; the LCD panel is arranged on a support surface of the middle frame; the middle frame comprises a plurality of member units, and a distance is reserved between two adjacent member units. The LCD device further includes a support member(s) used for assistantly supporting the LCD panel. The support member is provided with a hook, and the support member is hung on the side wall of the backplane by the hook. The support member(s) is positioned between two adjacent member units, and the support surface of the support member is flush with the support surface of the middle frame. The support member(s) of the LCD panel is additionally arranged on the LCD device of the invention, and the support member(s) is arranged between two member units when the distance between two adjacent member units is long, so as to enable the support force obtained by the LCD panel is more uniform, and prevent excessive local stress.

The invention provides a middle frame for an LCD device and an LCD device. The middle frame for an LCD device includes a receiving part corresponding to a light incident side of the LCD device, and a buffer part which is fixedly connected with the receiving part and corresponds to the non-light incident side of the LCD device; the receiving part is made of hard material, and the buffer part is made of flexible material. In the invention, because the middle frame is divided into a receiving part and a buffer part, the buffer part is made of flexible material and can be directly used for clamping the light guide panel to position the light guide panel, and the receiving part is made of plastic material which has certain hardness. Thus, the planeness of the whole middle frame can be kept. Furthermore, the position of the receiving part corresponding to the light source is made of plastic material and has certain high temperature resistance. The conventional middle frame is generally injection molded by plastic. However, the die for injection molding has the disadvantages of long manufacture cycle and high cost. The receiving part and the buffer part of the invention can be respectively molded, thereby simplifying the die structure, and favoring cost reduction.
