Description
Technical Field
The application belongs to the technical field of electronic products, and particularly relates to an electronic device.
Background
Many existing electronic devices still have a frame around the cover plate of the display module, and the frame has a wider width. Currently, reducing the width of the bezel is the main way to increase the screen ratio, because the width of the bezel affects the size of the non-display area on the cover. For the display module with the same size, the size of the screen occupation ratio depends on the size of the non-display area on the cover plate. The smaller the non-display area on the cover plate is, the larger the screen occupation ratio is; conversely, the larger the non-display area on the cover plate, the smaller the screen occupation ratio.
In the related art, referring to fig. 1, the cover plate 6 of the display module is assembled with the housing 7 of the electronic device by dispensing glue on the back surface of the cover plate 6, i.e. the back surface of the cover plate 6 is attached to the housing 7 by glue. In the existing assembly mode, the width of the shading ink area 4 needs to be increased on the back surface of the cover plate 6, so that a glue adhering area 5 with enough width is reserved on the shading ink area 4, and the width of the glue adhering area 5 is about 0.5 mm-2.0 mm, so that the connection reliability of the cover plate 6 and the shell 7 after adhering can be ensured. However, the dispensing assembly method also requires an assembly gap 8 between the cover plate 6 and the housing 7, which is caused by the large width of the light-shielding ink area 4, and this results in a large frame width of the electronic device, thereby resulting in a small screen occupation of the electronic device. Furthermore, glues used for bonding are generally resin materials that tend to age under prolonged sun exposure, resulting in reduced adhesion and reliability, and materials of this type are less resistant to acids and bases, e.g., perspiration on the hands of the user during use can cause the glue to degrade or even fail.
SUMMERY OF THE UTILITY MODEL
The application aims at providing an electronic equipment, solves the frame width size broad around the display module assembly on the current electronic equipment at least, and influences the problem that the screen accounts for the ratio.
In order to solve the technical problem, the present application is implemented as follows:
an embodiment of the present application provides an electronic device, which includes:
a housing comprising a sidewall and a bottom wall connected to the sidewall; and the number of the first and second groups,
the display module assembly, the display module assembly includes that display screen and lid are established printing opacity apron on the display screen, the lateral part of printing opacity apron with the lateral wall welded connection of casing.
In the embodiment of the application, when the display module is assembled for the electronic equipment, the connecting position of the light-transmitting cover plate and the shell is changed, and the welding connection mode is adopted, so that the side part of the light-transmitting cover plate is directly connected with the side wall of the shell in a tight and gapless manner, the width of a frame around the light-transmitting cover plate is narrowed, the size of a non-display area on the light-transmitting cover plate is reduced, and the screen occupation ratio of the electronic equipment can be improved.

The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
An electronic device according to an embodiment of the application is described below with reference to fig. 2 and 3. The electronic device may be, for example, a smartphone, a tablet computer, a notebook computer, a wearable device, an electronic book, and other various electronic products, which is not limited in this application.
The electronic device provided by the embodiment of the application is shown in fig. 2, and comprises a shell 1 and a display module 2, wherein the display module 2 is arranged on the shell 1. Wherein the housing 1 comprises a side wall 101 and a bottom wall 102 connected to the side wall 101. The display module 2 comprises a display screen 201 and a light-transmitting cover plate 202 covering the display screen 201, and the side portion 2021 of the light-transmitting cover plate 202 is connected with the side wall 101 of the casing 1 in a welding manner. That is to say, in the embodiment of the present application, when the display module 2 is assembled to the electronic device, the side portion 2021 of the transparent cover 202 in the display module 2 is fixedly connected to the side wall 101 of the housing 1 by welding. The electronic equipment provided by the embodiment of the application has the characteristics of narrow frame and high screen occupation ratio.
In the conventional electronic device, as shown in fig. 1, when a display module (the display module includes, for example, a display 9 and a cover plate 6 disposed on the display 9) is assembled, a circle of light-shielding ink region 4 is disposed at a back edge portion of the cover plate 6, and when the cover plate 6 is connected to a housing 7 of the electronic device by dispensing, a glue-bonding region 5 having a sufficient width is required on the light-shielding ink region 4. In fact, in order to facilitate the connection of the cover plate 6 and the housing 7, it is common in the art to design the side wall of the housing 7 as a multi-step structure, which may complicate the housing manufacturing process of the electronic device and also result in a large width dimension of the side wall of the housing 7. The back surface of the cover plate 6 can be bonded to a step surface on the side wall of the housing 7 by dispensing, wherein the width of the glue bonding area 5 is about 0.5mm to 2.0mm, which results in a larger width of the light-shielding ink area 4, and a certain assembly gap 8 is required between the housing 7 and the cover plate 6 for dispensing. The large width dimension of the light-shielding ink area 4 and the presence of the assembly gap 8 may result in a large bezel width of the electronic device, and thus may result in a small screen area of the electronic device. In addition, the existing glue for attaching is easy to age and poor in acid and alkali resistance, so that the adhesion and reliability of the glue are reduced. Therefore, the existing technical scheme for assembling the display module has a plurality of problems.
The electronic equipment of this application embodiment has adopted the technical scheme assembly display module assembly that is totally different with prior art. Specifically, in the embodiment of the present application, when the display module 2 is assembled to the electronic device, the connection position between the transparent cover 202 and the housing 1 is changed, and the side of the transparent cover 202 is directly connected to the side wall of the housing 1 in a tight and gapless manner by using a novel welding connection manner, so as to assemble the display module 2. This assembly helps to narrow the width of the bezel around the transparent cover 202 to reduce the size of the non-display area on the transparent cover 202, thereby improving the screen ratio of the electronic device. Moreover, when the transparent cover plate 202 and the shell 1 are connected, the fixed connection mode of welding connection is adopted, so that the reliability of connection between the transparent cover plate and the shell can be improved, and the defects of the existing dispensing mode are effectively overcome.
In an alternative example of the present application, referring to fig. 2, the housing 1 includes a sidewall 101 and a bottom wall 102 connected to the sidewall 101, wherein the sidewall 101 of the housing 1 has a straight wall structure. Compared with the side wall of a stepped structure in the related art, the structural design can simplify the overall structure of the shell 1, so that the manufacturing difficulty of the shell 1 can be reduced. More importantly, the width dimension of the side wall of the housing 1 can be made thin.
In the case that the side wall 101 of the housing 1 has a straight wall structure, as shown in fig. 3, the length of the light-transmitting cover plate 202 of the display module 2 is shortened by L1 compared with the prior art, and the length of L1 is usually 0.5mm to 1.0mm, so that the total width of the light-transmitting cover plate 202 can be reduced by 1.0mm to 2.0 mm. Therefore, the design can reduce the width of the light-transmitting cover plate 202, thereby reducing the material consumption and further reducing the production cost appropriately.
Specifically, the side wall 101 of the housing 1 may be, for example, a vertical wall structure. The ultra-narrow frame structure can better realize the ultra-narrow frame design of the electronic equipment.
Of course, the side wall 101 of the housing 1 may be inclined as appropriate as long as the assembly with the display module 2 is not affected. The side wall 101 of the housing 1 may be, but is not limited to, a vertical wall structure.
In addition, a stepped structure may be provided on the side wall 101 of the housing 1 as necessary. Alternatively, the side wall 101 of the housing 1 may have a curved structure. The skilled person in the art can reasonably adjust the specific structure of the side wall 101 of the housing 1 according to the assembly requirement, as long as the connection with the transparent cover plate 202 is facilitated and the width of the frame is not increased.
In an alternative example of the present application, a laser micro-welding connection is formed between the side portion of the light-transmissive cover plate 202 and the side wall 101 of the housing 1.
Specifically, in the embodiment of the present application, by using the ultrafast laser micro-welding method, the side wall of the housing 1 and the side portion of the light-transmissive cover plate 202 (i.e., two different materials) may be fused and then connected together using a very short infrared laser pulse, so that a stable and reliable connection relationship is formed therebetween. This is significantly better than the existing glue joint. Compared with glue, the laminating stability is better.
In the embodiments of the present application, laser welding is employed because: the welding width can be several micrometers, and the welding width replaces the gluing width of 0.5 mm-2.0 mm in the existing glue gluing and gluing process, so that the width of a shading ink area of the glue gluing and gluing platform can be reduced, and the ultra-narrow frame design of electronic equipment can be realized.
The laser can be focused by optical materials to form a very small and highly dense spot at the interface between the two different materials, which can bring the welded side walls of the housing 1 into close contact with the sides of the transparent cover plate 202, achieving peak power in the megawatt range in an area only a few microns wide, thus creating a microplasma surrounded by a highly confined melt area, achieving a reliable connection of the housing 1 to the transparent cover plate 202.
In the embodiment of the application, adopt laser welding to replace the technical scheme of current glue laminating, it is very firm at first between welded casing 1 and the printing opacity apron 202, in addition because the material composition after the welding still is the chemical composition of original material, its acid and alkali resistance and ageing resistance are better than resin nature glue, so the reliability is stronger.
In addition, in the embodiment of the application, the glue bonding is replaced by laser welding, so that the glue is not needed, the thickness of the glue is saved by about 0.1-0.3 mm, and the cost of the glue material is saved.
In an optional example of the present application, referring to fig. 2, the display module 2 includes a display screen 201 and a transparent cover plate 202 covering the display screen 201, and a light shielding layer 3 with a set width is disposed on a surface of the transparent cover plate 202 facing the display screen 201 along an edge region.
That is, the light shielding layer 3 is provided on the back surface of the light-transmitting cover plate 202 at the edge positions of four sides. The light shielding layer 3 is designed to shield light leakage at the edge of the display panel 201.
The light-shielding layer 3 is, for example, an opaque ink layer.
Specifically, the light-shielding layer 3 is a black ink layer.
The light shielding layer 3 may be formed in an edge area on a surface of the light-transmitting cover plate 202 facing the display screen 201 by silk-screen printing, transfer printing, jet printing, or the like. Thus, the light-shielding layer can be directly formed on the light-transmitting cover plate 202 in a simple manner without increasing the dimension in the thickness direction.
In the embodiment of the present application, referring to fig. 2, the side edge of the light shielding layer 3 abuts or contacts with the side wall 101 of the housing 1. This is also different from the related art, in which the back surface of the light-shielding ink region 4 is in contact with the side wall of the housing 7 of the electronic device, as shown in fig. 3.
In the embodiment of the present application, referring to fig. 3, the length of the light-transmitting cover plate 202 of the display module 2 is shortened by L1, i.e. 0.5mm to 1.0mm, compared to the prior art, and the total width of the light-transmitting cover plate 202 can be reduced by 1.0mm to 2.0 mm. Since the width of the light-transmitting cover plate 202 is reduced, the width of the light-shielding layer 3 thereon is also reduced by 0.5mm to 1.0mm on one side and 1.0mm to 2.0mm on both sides. The shading layer 3, for example, the printing ink silk screen area is reduced, the printing ink materials are reduced, and the cost can also be effectively reduced.
By taking a commonly-used mobile phone as an example, the technical scheme provided by the embodiment of the application can reduce the width of the shell of the mobile phone by 1.0-2.0 mm compared with the existing scheme, so that the material cost of the shell material can be reduced. And for the current 20: 9 or 19: the full-screen mobile phone of 9 can be beneficial to a user to operate the mobile phone with one hand if the width is relatively narrow. That is to say, after the scheme in this application is applied to the cell-phone, the width size of reducible cell-phone is favorable to promoting user's one-hand operation's scope and user experience.
In an alternative example of the present application, the light-transmissive cover plate 202 is a glass cover plate. The glass cover plate has good light transmission, the use of the display screen 201 cannot be influenced, and meanwhile, the display screen 201 can be well protected.
Specifically, the light-transmissive cover plate 202 may be, for example, a 2.5D glass cover plate. The 2.5D glass is generally soda-lime glass, aluminosilicate glass or lithium aluminosilicate glass, and belongs to transparent optical glass. The use of the display screen 201 is not affected, and the display screen 201 can be well protected.
In an alternative example of the present application, both sides of the light-transmissive cover plate 202 extend beyond both sides of the display screen 201.
In the embodiment of the present application, referring to fig. 2, the width dimension of the light-transmitting cover plate 202 is larger than the width dimension of the display screen 201, and this design enables the light-transmitting cover plate 202 to provide better protection for the display screen 201.
In an embodiment of the present application, the display screen 201 is a human-computer interaction interface.
The display screen 201 may be, but is not limited to, an Organic Light-Emitting Diode (OLED) display screen. The OLED screen is thinner, low in energy consumption, high in brightness, good in luminous efficiency, capable of displaying pure black and capable of being bent.
In the embodiment of the present application, the housing 1 may be a metal housing or a plastic housing. The casing 1 can protect the internal components of the whole machine from the back, including but not limited to the display screen 201.
For example, the material of the housing 1 is an aluminum alloy material, a magnesium alloy material, or a titanium alloy material.
The housing 1 may be of an integrated structure, for example.
The technical scheme that this application embodiment provided, be connected for laser welding between the printing opacity apron 202 of display module assembly 2 and electronic equipment's the casing 1, printing opacity apron 202 is the glass material, and the casing 1 of complete machine is alloy material, and these materials are the material of antiacid alkali again, and its acid and alkali-resistance after the welding, ageing resistance can compare current resinous glue and have had very big promotion. The electronic equipment provided by the embodiment of the application has the characteristic of an ultra-narrow frame, and the screen occupation ratio of the electronic equipment can be effectively improved.
