Detailed Description
The invention will be further explained with reference to the embodiments of the drawings.
Example 1
The ultra-thin backlight module shown in fig. 3 mainly includes a light guide plate assembly 11, a liquid crystal assembly 12 and a supporting assembly 13.
The supporting assembly 13 includes a frame 131 and a back plate 132, the back plate 132 is matched with the frame 131 and covers the frame 131, and a recess is formed on one side of the frame 131 corresponding to the back plate 132, so that an accommodating space 133 is formed between the frame 131 and the back plate 132.
The light guide plate assembly 11 is installed in the accommodating space 133, and its structure can be referred to the structure of the existing light guide plate assembly, and it includes a reflective layer 113, a light guide plate 111, and an optical film 112 (the light guide plate 111 and the reflective layer 113 can be integrally set, such as a film-coated glass light guide plate, which is beneficial to reducing the thickness), which are sequentially stacked, and a light source 115 corresponding to the light guide plate 111, the light guide plate 111 generally has a light incident surface, a light emitting surface, and a light reflecting surface, in this embodiment, the light guide plate 111 has a light emitting surface contacting the optical film 112, a light reflecting surface contacting the reflective layer 113, and a light incident surface located in front of them, and the light source 115 (generally, an LED lamp) corresponds to the light incident surface of the light guide plate 111. The reflective layer 113 in the light guide plate assembly 11 is close to the back plate 132 and the optical film 112 faces away from the back plate 132. The light source 115 is generally mounted on the side of the light guide plate 111 by means of a light bar bracket 114; one portion of the light bar support 114 is fixed to the back plate 132 and the other portion extends through the side of the light guide plate assembly 11 to connect with the optical film 112. In this embodiment, the light bar bracket 114 has a first fixing portion, a second fixing portion and a connecting portion connecting the first fixing portion and the second fixing portion; the first fixed portion is fixed to the back plate 132, and the second fixed portion is fixed to the surface (usually the upper surface) of the optical film 112, so that the first fixed portion is usually parallel to the second fixed portion; the connection part is positioned at one side of the light guide plate 111 for mounting the light source 115; the included angle between the connecting portion and the first fixing portion or the second fixing portion is 45 to 90 degrees (preferably 90 degrees), which is beneficial to installing the light source 115 and saving space to improve space utilization rate, so that the end surface of the light bar support 114 is Z-shaped (i.e. appears Z-shaped from the side surface).
The liquid crystal assembly 12 is of an existing conventional structure, comprises a liquid crystal screen 121, a PCB 122 and an IC circuit 123, and can be purchased commercially; it is also installed in the accommodating space 133. In the existing ultra-thin backlight module structure, on one hand, the light guide plate assembly 11 needs to be covered by the rubber frame 116'; on the other hand, the liquid crystal glass 122' and the PCB 123' are respectively located at two sides of the light guide plate assembly 11, and need to be fixed on the backlight front frame 124' by screws, which is complex in structure and many in parts. In this embodiment, the liquid crystal panel 121 is directly fixed on the frame 131 through glue and is located between the frame 131 and the optical film 112, and the liquid crystal panel is not fixed through screws, so that structural members such as a glue frame, a module front frame, screws and the like are omitted; the PCB 122 and the lcd 121 are located on the same side of the light guide plate assembly 11, and are connected and fixed to the lcd 121, close to the inner surface of the frame 131. Because the thickness of the existing ultrathin backlight module (actually, the thickness of the backlight module 11 'and the liquid crystal assembly 12') is usually 20mm, and the thickness of the whole touch integrated machine reaches 50mm; by adopting the structure in the embodiment, the thickness of the touch integrated machine can be reduced to about 6mm, the thickness of the whole touch integrated machine is reduced to about 25mm, the thickness of the whole touch integrated machine is reduced by more than 50%, and the ultra-thinning of the touch integrated machine, especially the backlight module, is realized.
Example 2
As shown in fig. 4, the touch integrated machine includes the ultra-thin backlight module 1 and the touch screen 2 in embodiment 1. In order to reduce the thickness of the touch all-in-one machine, a first groove portion 134 may be formed on a surface (an upper surface in fig. 4) of the frame body 131, so that the first groove portion 134 is communicated with the accommodating space 133, and thus the touch screen 2 is directly fixed in the first groove portion 134 by glue, thereby avoiding using an additional aluminum frame, and reducing the thickness and the material consumption, and reducing the cost.
The above-mentioned embodiments are provided only for illustrating the technical idea and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the content of the present invention and to implement the present invention, and not to limit the protection scope of the present invention by this, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
