In order to make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims.

The embodiment of the present application provides a support 100 for a backlight module 10, and the backlight module 10 may include a substrate 200 and a diffusion plate 300 spaced apart from the substrate 200. The backlight assembly 10 may further include a light source disposed between the substrate 200 and the diffusion plate 300. The diffusion plate 300 serves to diffuse light emitted from the light source.

The supporter 100 is disposed between the substrate 200 and the diffusion plate 300, and supports the diffusion plate 300. Because of the support 100, the portion of the diffuser plate 300 contacting the support 100 is prone to generate a dark shadow, and in the embodiment of the present invention, the support 100 is configured to emit fluorescence to reduce the dark shadow. When light is irradiated to the supporting member 100, the supporting member 100 can convert the light into fluorescence to emit light, so as to reduce or even eliminate a dark area on the diffusion plate 300, thereby effectively improving display quality.

The support 100 may be configured to fluoresce either when the support 100 is configured to fluoresce in its entirety or when the support 100 is configured to fluoresce in part. The support 100 is configured to emit fluorescence as a whole and may be: the support 100 is made of a material containing a fluorescent material; for example, the support 100 may be a light-transmissive housing and a fluorescent material located within the light-transmissive housing; in this case, the fluorescent material may be filled in the light-transmitting case, or the fluorescent material may be coated only on the inner surface of the light-transmitting case. The support 100 may be configured to emit fluorescence as a whole, or the support 100 may be made of a fluorescent material mixed with other light-transmissive materials. The support 100 may be configured to emit fluorescence in its entirety: the support member 100 has a fluorescent layer coated on an outer surface thereof; the fluorescent layer is made of fluorescent materials. The fluorescent material can be fluorescent powder or fluorescent dye. The light transmissive material may be plastic; such as polymethyl methacrylate, polycarbonate or polystyrene.

The shape of the support 100 may be arbitrary; for example, the support 100 may include only one sheet, or may include a plurality of sheets. For convenience of description, the detailed structure of the supporting member 100 will be described in detail with the use state of the supporting member 100 in the backlight module 10; for example, when the supporter 100 includes only one plate, one end of the supporter 100 may be connected to the substrate 200, and the other end of the supporter 100 may abut against the diffusion plate 300. When the supporting member 100 includes a plurality of plates, the following detailed description will be made on a specific structure of the supporting member 100 when two plates are included, the supporting member 100 may include a mounting plate 110 and a supporting plate 120, and the mounting plate 110 may be attached to the substrate 200; one end of the support plate 120 may be connected to the mounting plate 110, and the other end of the support plate 120 may abut against the diffusion plate 300.

When the supporting member 100 is a plate, in order to stably fix the supporting member 100 on the substrate 200, an end surface of the supporting member 100 attached to one end of the substrate 200 may be a flat surface, so that the supporting member 100 is in surface-to-surface contact with the substrate 200. In order to reduce the contact area between the supporter 100 and the diffuser 300, the end surface of the supporter 100 abutting against one end of the diffuser 300 may be a curved surface, so that the supporter 100 and the diffuser 300 are in line-surface contact. In order to ensure the stable fixation of the supporter 100 and the substrate 200 and reduce the contact area between the supporter 100 and the diffuser plate 300, the supporter 100 may further include a connecting portion attached to the substrate 200 and an abutting portion extending from the connecting portion to the diffuser plate 300 and converging at a point, and an end surface of the connecting portion attached to one end of the substrate 200 is a plane, so that the connecting portion is in surface-to-surface contact with the substrate 200 and the abutting portion is in point-to-surface contact with the diffuser plate 300. Of course, in order to avoid the wear of the diffuser plate 300 caused by the support 100 in the case of point-to-surface contact, a dome may be provided at one end of the abutting portion away from the connecting portion. When the support 100 is a plate, the support 100 may be configured to emit fluorescence in its entirety, or the support 100 may be configured to emit fluorescence in its part.

When the supporting member 100 is two plates including the mounting plate 110 and the supporting plate 120, in order to stably fix the mounting plate 110 on the substrate 200, an end surface of the mounting plate 110 attached to one end of the substrate 200 may be a flat surface, so that the mounting plate 110 and the substrate 200 are in surface-to-surface contact. In order to reduce the contact area between the support plate 120 and the diffusion plate 300, the end surface of the support plate 120 abutting against one end of the diffusion plate 300 may be a curved surface, so that the support plate 120 and the diffusion plate 300 are in line-surface contact. To reduce the contact area between the supporter 100 and the diffuser 300, the supporting plate 120 may extend from one end of the mounting plate 110 to the diffuser 300 and converge at a point, so that the supporting plate 120 and the diffuser 300 are in point-surface contact. Of course, in order to avoid the wear of the diffuser plate 300 caused by the support plate 120 when the point-surface contact occurs, a dome may be provided at the end of the support plate 120 away from the mounting plate 110.

When the support 100 is a two-piece plate including the mounting plate 110 and the support plate 120, the support 100 may be configured to emit fluorescence, or only the support plate 120 may be configured to emit fluorescence. The support plate 120 may include a connection part 121 to which the mounting plate 110 is connected, and an abutting part 122 to abut against the diffusion plate 300; the support 100 may be configured to fluoresce when the abutment 122 is configured to fluoresce. To eliminate the dark shadow area on the diffusion plate 300 and save fluorescent material, the height of the abutting portion 122 may be one half to one fifth of the distance between the diffusion plate 300 and the substrate 200. The support plate 120 is configured to emit fluorescent light and may be such that the support plate 120 comprises a light transmissive housing 123 and a fluorescent material located within the light transmissive housing 123; the fluorescent material may be filled in the light-transmissive case 123, or the fluorescent material may be coated only on the inner surface of the light-transmissive case 123. Support plate 120 may be configured to emit fluorescent light or support plate 120 may have a phosphor layer 124 coated on an outer surface thereof. The support plate 120 may be configured to emit fluorescent light, or the support plate 120 may be made of a fluorescent material mixed with other light-transmissive materials.

When the supporting member 100 is a plate, the supporting member 100 and the substrate 200 are preferably bonded by glue. When the supporting member 100 is two plates including the mounting plate 110 and the supporting plate 120, the mounting plate 110 and the base plate 200 may be bonded by glue or may be connected by a fastener such as a screw. When the mounting plate 110 is connected to the base plate 200 by a fastening member such as a screw, the mounting plate 110 may be provided with at least one threaded hole 111.
