Background
With the development of display technology, full-screen technology has emerged, and such technology is widely used in various electronic devices such as cellular phones, and such cellular phones employing full-screen technology are called full-screen cellular phones.
In a full-screen mobile phone, a camera is usually required to be placed in an effective display area of the mobile phone, so that holes are required to be dug in the corresponding effective display area when the liquid crystal display module of the mobile phone is designed correspondingly.
At present, the scheme of digging holes in the effective display area of the liquid crystal display module generally comprises digging holes in both the liquid crystal panel and the backlight module, or digging through only the backlight module, and the two schemes can enable the liquid crystal display module after digging holes to have no display function in the digging hole area of the effective display area after being lightened.
However, in the existing backlight module design, a design scheme of "iron frame+plastic frame" is adopted at the boundary of the hole digging area, so as to fix devices, such as a camera, a microphone, etc., installed in the hole digging area. Since the plastic frame is fixed on the edge of the iron frame, there is a problem that the width of the border of the hole digging area is wider, which affects the appearance of the liquid crystal display module, as shown in fig. 1.
In the industry, in order to solve the above-mentioned problems, a technical solution is generally adopted to reduce the width of the rubber frame as much as possible. However, the width of the adhesive frame can be reduced to 0.9mm at most, because if the width of the adhesive frame is smaller than 0.9mm, on one hand, the adhesive tape between the adhesive frame and the lower polarizer in the backlight module is not sufficiently adhered, and on the other hand, the edge of the film material is too close to the effective display area, so that the problems of light leakage in the hole and light leakage at the edge of the effective display area are caused.
Therefore, how to reduce the boundary width of the hole digging area becomes a problem to be solved.

Detailed Description
The embodiment of the application provides a backlight module and a display device, which are used for solving the technical problem of wider boundary width of a hole digging area in the prior art.
The technical scheme in the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:
provided is a backlight module, including: the backlight module comprises an iron frame, a backlight source, a light guide plate and a film material, wherein the iron frame is used for supporting the backlight source, the light guide plate and the film material. Specifically, the backlight module is provided with a through hole; wherein, the through hole penetrates through the light guide plate and the membrane material; the iron frame comprises an iron frame body and a cylindrical structure positioned at the position of the through hole, and the iron frame body extends along the inner wall of the through hole to form the cylindrical structure.
Since in the above scheme, by setting the backlight module as: the light guide plate is provided with the through hole, the through hole penetrates through the light guide plate and the film material, the iron frame body is located at the position of the through hole and extends along the inner wall of the through hole to form a cylindrical structure, on one hand, light rays inside and outside the hole of the hole digging area can be blocked through the cylindrical structure, and on the other hand, the function of fixing devices in the hole when the rubber frame is used can be achieved, so that the rubber frame is not needed in the scheme as in the prior art, the boundary width of the hole digging area is not limited by the width of the rubber frame, and the technical effect of reducing the boundary width of the hole digging area is achieved.
In order to better understand the above technical solutions, the following detailed description of the technical solutions of the present application is made by using the accompanying drawings and specific embodiments, and it should be understood that the specific features of the embodiments and the embodiments of the present application are detailed descriptions of the technical solutions of the present application, and not limiting the technical solutions of the present application, and the technical features of the embodiments and the embodiments of the present application may be combined with each other without conflict.
Referring to fig. 2 and 3, a backlight module 200 is provided in an embodiment of the application, and fig. 1 is a schematic diagram of the backlight module 200.
The cross section of the hole digging position (i.e., the position corresponding to the dotted line in fig. 2) corresponding to the backlight module 200 is shown in fig. 3: the backlight module 200 includes a frame 201, a backlight 202 (not shown), a light guide plate 203 and a film 204, wherein the frame 201 is used for supporting the backlight 202, the light guide plate 203 and the film 204. The backlight 202 is usually located at one side of the iron frame 201, and is a side-emitting LED, and is used for providing a backlight source for the entire backlight module, and the light guide plate 203 is used for effectively distributing the light emitted by the backlight 202 in the backlight window area to form a surface light source.
The film 204 includes a reflective sheet 2041, a diffusion sheet 2042, and a light enhancement sheet 2043. The reflection sheet 2041 is located between the iron frame 201 and the light guide plate 203, the diffusion sheet 2042 is located on the other side surface of the light guide plate 203 opposite to the reflection sheet 2041, and the light enhancement sheet 2043 is located on the other side surface of the diffusion sheet 2042 opposite to the light guide plate 203. The reflective sheet 2041 is used for recycling light guided from the light guide plate, the diffusion sheet 2042 is used for atomizing light to achieve a surface light source effect, and the light enhancement sheet 2043 is used for converging light and improving module brightness.
Specifically, the backlight module 200 has a through hole 206, and the position of the through hole 206 in fig. 3 is the position of the dashed line in the drawing; the through hole 206 penetrates the light guide plate 203 and the film 204.
For example, the through holes 206 may penetrate the reflective sheet 2041, the reflective sheet 2041 and the diffusion sheet 2042 in the film 204, may penetrate the reflective sheet 2041, the diffusion sheet 2042 and the light enhancement sheet 2043, or may penetrate the entire film 204 (i.e. the reflective sheet 2041, the diffusion sheet 2042 and the light enhancement sheet 2043) as the bus in fig. 3, and the specific components of the through holes 206 penetrating the film 204 are not limited herein.
It should be understood that, as technology advances and the backlight module process improves, the components of the film 204 may change, so the specific penetrating portion of the film 204 is not to be construed as a limitation of the present application. Also, in fig. 2, the positions of the through holes 206 (hole digging positions) in the backlight module 200 are only shown as examples, and the through holes 206 may be located at any position of the backlight module 200 according to actual needs, so the specific positions of the through holes 206 in fig. 2 should not be limited.
By allowing the through holes 206 in the backlight module 200 to penetrate through the light guide plate 203 and the film 204, the area where the through holes 206 are located can be reduced or even no light emitted by the backlight 202 passes through. So that the display screen assembled by the backlight module 200 does not display a picture in the region of the through hole 206.
Referring to fig. 4 and 5, the iron frame 201 includes an iron frame body 2011 and a cylindrical structure 2012 located at a position of the through hole 206, and the iron frame body 2011 extends along an inner wall of the through hole 206 to form the cylindrical structure 2012.
Specifically, please refer to the perspective view of the iron frame 201 (fig. 4) and the hatched area of the corresponding cross-section view (fig. 5).
The iron frame body 211 and the tubular structure 2012 are made of the same material and are integrally formed by the same process. For example, the iron frame body 2011 may be punched to form the cylindrical structure 2012 at the punched portion of the iron frame body 2011, or the iron frame 201 may be integrally formed by casting with a mold to form the iron frame 201 into the iron frame body 2011 and the cylindrical structure 2012. Of course, as the technology advances, new processes may occur, and the frame 201 may be formed, so the specific process used to obtain the structure of the frame 201 is not limited herein.
The above structure of the iron frame 201 is obtained by integrally forming the same material under the same process, so that the structure of the iron frame 201 is simpler and the reliability is better.
In the embodiment provided by the present application, the tubular structure 2012 of the iron frame 201 is opaque. For example, the material used for the tubular structure 2012 itself may be opaque, or the tubular structure 2012 may be made opaque by plating nickel or paint on the tubular structure 2012.
Light outside the tubular structure 2012 (such as light in the backlight 203 and the film 204) can be effectively prevented from being projected into the through hole 206 of the backlight module 200 by making the tubular structure 2012 of the iron frame 201 opaque. Therefore, the cylindrical structure 2012 of the iron frame 201 is made opaque to achieve the effect of light leakage prevention.
In the embodiment provided by the present application, the cylindrical structure 2012101b of the backlight module 200 can also be used for devices, such as a camera, a microphone, etc., fixedly mounted in the through hole 206. In the prior art, devices in the through holes are fixed by a rubber frame.
In the embodiment provided by the application, the cylindrical structure 2012 of the iron frame 201 can play a role of blocking the light inside and outside the hole of the through hole 206, and can play a role of fixing the device in the hole of the through hole 206 when the rubber frame is used in the prior art, so that the rubber frame is not required to be used when the iron frame 201 with the cylindrical structure 2012 is used for designing and manufacturing the backlight module 200, as in the prior art, so that the boundary width of the hole digging area is not limited by the width of the rubber frame, and the technical effect of reducing the boundary width of the hole digging area is realized. Further, since the iron frame body 2011 and the tubular structure 2012 are integrally formed, the iron frame can have a simpler structure, so that the process flow of the iron frame can be simplified, and the efficiency of manufacturing the backlight module is improved.
In the embodiment provided in the present application, any cross-section of the tubular structure 2012 of the iron frame 201 is a closed shape, for example, may be any of a circle, an ellipse, a square, a diamond, etc., and specifically, refer to fig. 6-9 (fig. 6 is a circle, fig. 7 is an ellipse, fig. 8 is a square, and fig. 9 is a diamond).
Since the shape of any cross section of the tubular structure 2012 of the iron frame 201 is a closed shape, the stability of the device mounted in the through hole 206 can be improved.
In the embodiment provided by the present application, the side surface of the film 204 of the backlight module 200, which is close to the cylindrical structure 2012, is provided with a first light absorbing structure 207, and the specific first light absorbing structure 207 may be formed by a silk-screen method.
Taking the diffusion sheet 2042 in the film 204 as an example, please refer to fig. 10. The side surface of the diffusion sheet 2042, which is close to the cylindrical structure 2012 of the iron frame 201, is provided with the first light absorption structure 207, so that the problem of bright lines at the edge of the film material can be improved, and light leakage around the through hole 206 of the backlight module 200 can be reduced.
It should be understood that the first light absorbing structure 207 may also be located in other components of the film 204, specifically, should be a portion of the film located above the light guide plate 203, such as the diffusion sheet 2042 and the light enhancement sheet 2043.
In the embodiment of the application, the backlight module 200 further has a first polarizer 205 for controlling the direction of light passing through, and the first polarizer 205 is located at the top of the backlight module 200. The first polarizer 205 is penetrated by the through hole 206, and a second light absorbing structure 208 is disposed on one side of the first polarizer 205 near the through hole 206, and the second light absorbing structure 208 may be formed by silk-screen printing. In this way, the problem of the surrounding of the through hole 206 shining can be improved, and the technical effect of preventing light leakage can be achieved.
Referring to fig. 11, according to the same inventive concept, a display device 11000 is provided in an embodiment of the application, and the display device 11000 has a display panel 11001 and a backlight module 200 as described above.
In the embodiment provided by the application, the display panel 11001 includes a display area 11001a and a non-display area 11001b surrounded by the display area 11001a, and the non-display area 11001b at least partially overlaps with the orthographic projection of the through hole 206 of the backlight module 200. Referring to fig. 12, the boundary of the hole digging area in the non-display area 11001b is orthographically projected on the tubular structure 2012 (shown by a dotted line portion in fig. 12) of the iron frame 201.
Further, since the display device 11000 has the backlight module 200, and the backlight module 200 only adopts the iron frame 201 at the position of the through hole 206, the design scheme of "iron frame+glue frame" in the prior art is not required, so that the border width of the hole digging area is not limited by the glue frame any more.
In the embodiment provided by the application, the width of the boundary of the hole digging area (i.e. the position of the non-display area 11001b of the display panel 11001) can be effectively reduced (the width can reach the thickness of the iron frame 201, such as 0.1 mm) by adopting the design of the iron frame only, so that the boundary design of a narrower hole digging area can be realized, the aesthetic degree of the display device can be improved, and the electronic device (such as a mobile phone, a tablet personal computer and the like) can be more attractive and the user experience can be improved when the display device is used for designing the electronic device for the rear end.
Referring to fig. 13, a specific display panel 11001 is composed of a liquid crystal panel 110011, an upper polarizer 110012, an optically transparent adhesive 110013, and a cover plate 110014, wherein the cover plate 110014 may be a touch screen.
