Description
Technical Field
The present invention relates to a display module and a backlight module thereof, and more particularly, to a display module with a narrow frame and a backlight module thereof.
Background
Liquid crystal displays have become the mainstream of display devices. In various fields, there are different requirements for liquid crystal displays, for example in the medical field, which generally require better reliability, product lifetime and higher contrast of the display. Furthermore, medical displays typically combine multiple lcd displays into a large screen that displays a single, integral image. The frame of the backlight module is assembled by the whole liquid crystal display, and an area which does not display images cannot be avoided. In addition, the liquid crystal display device has a region called a frame, which is generated in consideration of the entire structural strength and the assembling strength of the internal member, in addition to the display purpose. When the frame (i.e., the edge (border) portion of the display screen is not substantially displayed) of each lcd is too large, the gap between the frames is too large, which may affect the interpretation of the images by medical personnel. Therefore, the medical monitor requires the frames between the liquid crystal displays to be reduced as much as possible, so that the medical staff can judge the disease condition more conveniently.
In addition, medical displays need to be moved from time to time for different applications. Therefore, the requirement for product reliability is much higher than that of general consumer electronics displays. Therefore, the reliability of the backlight module in the display is higher than that of the display for general consumer electronics.
The conventional backlight module for display is formed by assembling a light guide plate, a bottom plate and a side frame. However, since one side of the backlight module includes the frame and the bottom plate formed by plastic, a gap (for example, the gap is greater than 6 mm) between the side of the backlight module and the light guide plate is too large.
Therefore, it is desirable to provide a display module and a backlight module thereof to solve the problems of the prior art.

The following description refers to the same or similar elements with the same or similar reference characters.
Referring to fig. 1, an exploded view of a backlight module according to a first embodiment of the invention is shown. The backlight module 1 comprises: a first carrier 10; a light guide plate 20 disposed on the first carrier 10, the light guide plate 20 having a left side L and a right side R; and a second supporting member 30 symmetrically disposed on the left side L and the right side R of the light guide plate 20, respectively, wherein the second supporting member 30 has a first bending portion 31, a connecting portion 32 and a second bending portion 33, the first bending portion 31 is correspondingly disposed on an upper surface of the light guide plate 20, the connecting portion 32 is correspondingly disposed on a side of the light guide plate 20, and the second bending portion 33 is correspondingly disposed on a lower surface of the first supporting member 10, so that the second supporting member 30 encloses the light guide plate 20 and the first supporting member 10.
Optionally, an optical film 40 is further disposed on the light guide plate 20. In one embodiment, the optical film sheet 40 is a multilayer optical film structure, for example, selected from the group consisting of: a lower diffusion layer, a prism structure layer, an upper diffusion layer, a micro-lens layer, a polarizer layer and their combination. The optical film 40 may be a prefabricated optical film, and is disposed on the light guide plate 20 when the backlight module 1 is assembled. Alternatively, the optical film 40 may be a plurality of film layers directly formed on the light guide plate 20. In this preferred embodiment, the second carrier 30 simultaneously encloses the first carrier 10, the light guide plate 20, the optical film 40 and the first carrier 10, and the first bent portion 31 of the second carrier 30 abuts against an upper surface of the optical film 40.
Optionally, the material of the first carrier 10 is a first metal for carrying the light guide plate 20. A reflective layer (not shown) may be disposed between the first carrier 10 and the light guide plate 20.
In one embodiment, the first carrier 10 has a side wing 11 corresponding to a front side F and a rear side B of the light guide plate 20, but the first carrier 10 does not have the side wing 11 corresponding to the left side L and the right side R of the light guide plate 20, so that the connecting portion 32 of the second carrier 30 can be closer to the side of the light guide plate 20. Furthermore, the second carrier 30 is an Contraband-shaped member integrally formed and the material of the second carrier 30 is a second metal, and is formed by stamping. In this embodiment, the front side F and the back side B of the light guide plate 20 further include a plastic frame 50 for coupling the side wings 11 of the first supporting member 10 and limiting the light guide plate 20 or the optical film 40. In one embodiment, the plastic rim 50 is formed by plastic injection molding.
Next, referring to fig. 2, a cross-sectional view of a display module 2 according to a second embodiment of the invention is shown. The display module 2 includes: a first carrier 10; a light guide plate 20 disposed on the first carrier 10, the light guide plate 20 having a left side L and a right side R; a second supporting member 30 symmetrically disposed on the left side L and the right side R of the light guide plate 20, respectively, wherein the second supporting member 30 has a first bending portion 31, a connecting portion 32 and a second bending portion 33, the first bending portion 31 is correspondingly disposed on an upper surface of the light guide plate 20, the connecting portion 32 is correspondingly disposed on a side of the light guide plate 20, and the second bending portion 33 is correspondingly disposed on a lower surface of the first supporting member 10, so that the second supporting member 30 encloses the light guide plate 20 and the first supporting member 10; and a display panel 60 disposed on an upper surface of the first bending portion 31 of the second supporting member 30.
Optionally, the connecting portion 32 is parallel to the side edge of the light guide plate 20. In addition, an optical film 40 may be disposed on the light guide plate 20, and the first bending portion 31 of the second carrier 30 is disposed on an upper surface of the optical film 40. The display module 2 also includes a protector (not shown) attached to the upper surface of the optical film 40. In one embodiment, the protection member is a light-transmitting film for protecting the optical film 40 from being worn by the first bending portion 31 of the second bearing member 30.
Furthermore, the display panel 60 may be connected to the first bending portion 31 through a buffer 70. In one embodiment, the buffer member 70 is a transparent adhesive tape adhered to an upper surface of the first bending portion 31 of the second supporting member 30 to provide a supporting force and a buffering force for the display panel 60. A protrusion 51 of a plastic frame 50 is clamped between the display panel 60 and the optical film 40 and near a front side F and a rear side B of the light guide plate 20, and is configured to limit the positions of the display panel 60 and the optical film 40 or provide a supporting force between the display panel 60 and the optical film 40. In the embodiment, the first supporting member 10 and the second bending portion 33 of the second supporting member 30 are fastened by a screw 80.
In a specific embodiment, the material of the first supporting member 10 is a first metal and the material of the second supporting member 30 is a second metal. The second carrier 30 is an Contraband-shaped piece integrally formed and formed by stamping. Alternatively, the second bearings 30 may be formed by precision machining to reduce manufacturing tolerances of each second bearing 30. In this embodiment, the second supporting members 30 are respectively disposed on the left side L and the right side R of the light guide plate 20. The second bearing members 30 of the left side L and the right side R are separated from each other and the first bearing members 10, and then are combined and locked by the screws 80 (the number of the screws is configured according to actual needs, only one of which is shown in the figure), so that convenience in assembly and sufficient structural strength are provided.
Furthermore, the display panel 60 is a low temperature polysilicon display panel. The arrangement of the low temperature polysilicon display panel on the second carrier 30 can provide sufficient flatness. Compared with the existing plastic frame, due to manufacturing tolerance and material limitation, sufficient flatness cannot be provided for the low-temperature polysilicon display panel. The second carrier 30 of the present invention can provide the required flatness for the low temperature polysilicon display panel and provide sufficient structural strength, and the reliability is not affected by insufficient structural strength caused by shortening the frame distance. In this embodiment, the connecting portion 32 of the second supporting member 30 and the side edge of the light guide plate 20 define a distance, and the distance is less than or equal to 3.5 mm, for example, 3.5 mm, 3 mm, 2.5 mm, 2 mm, 1.5 mm, 1.0 mm, 0.5 mm, and the like. Therefore, compared with the conventional display frame which is often larger than 6 mm, the frame structure provided by the invention can greatly shorten the size of the frame.
