Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present invention, and the embodiments may be mutually incorporated and referred to without contradiction.
It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.
It will be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, as used herein, refer to an orientation or positional relationship indicated in the drawings, which is solely for the purpose of facilitating the description and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and is therefore not to be construed as limiting the invention.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
The display device is a display tool which displays a certain electronic file on a screen through a specific transmission device and reflects the electronic file to human eyes. It can be divided into various types such as Cathode Ray Tubes (CRT), Liquid Crystal Displays (LCD), and the like.
Among them, the liquid crystal display device is a passive light emitting flat panel display device, has low power consumption, small radiation, and good display effect, and has become a mainstream product in the market.
The applicant has found that, in the prior art, as shown in fig. 1, the touch panel 40, the liquid crystal module 30 and the backlight module 20 are usually connected in sequence to form a fixed structure, and then the fixed structure is directly assembled into the housing 10 to complete the assembly of the display device. In this arrangement, the backlight module 20 can protect its components by the tape unit 21. The glue iron structure 21 causes the distance between the side wall of the shell 10 of the display device and the edge of the display area to be too wide, so that the plane size of the whole machine is increased; meanwhile, the backlight module 20 cannot directly contact with the bottom wall of the housing 10, which increases the thickness of the whole device. Since there is a gap between the backlight module 20 and the housing 10, if the assembly is deviated or rigid contact occurs due to stress, glass is easily broken and the backlight is easily deformed, which finally results in poor display.
Based on the above problems and the purpose of reducing the size of the whole display device, the inventor has developed a display device, which eliminates the glue iron structure of the backlight module on the existing basis, eliminates the gap between the backlight module and the casing by integrating the backlight module into the casing, and solves the problem that the backlight module without the glue iron structure has insufficient strength.

In one embodiment of the present application, as shown in fig. 4 and fig. 5, the touch panel includes a touch panel 400 and a liquid crystal module 500, which are attached to each other, the size of the touch panel 400 is larger than that of the liquid crystal module 500, and the touch panel 400 includes a central portion facing the liquid crystal module 500 and an edge portion surrounding the central portion and located around the liquid crystal module 500; a second bearing step 122 is further disposed on the inner side of the sidewall 120, the first bearing step 121 is located between the bottom wall 110 and the second bearing step 122, and a plane where a side surface 122b of the second bearing step and a top surface 121a of the first bearing step are located forms a second groove; the height difference between the top surface 122a of the second loading step and the top surface 121a of the first loading step in the direction perpendicular to the bottom wall 110 is greater than or equal to the sum of the thickness of the liquid crystal module 500 and the thickness of the light-shielding member 300; the edge portion of the touch panel 400 is disposed on the top surface 122a of the second supporting step, and the liquid crystal module 500 is accommodated in the second groove.
In the embodiment of the present invention, the touch panel 400 and the liquid crystal module 500 are connected to form a fixing structure, and the backlight module 200 and the housing 100 also form a fixing structure, and only the two fixing structures need to be assembled during assembly. The surface size of the touch panel 400 is larger than the size of the liquid crystal module 500, so that on one hand, all ranges of the liquid crystal module 500 on the plane are covered, and the touch screen operation is facilitated; on the other hand, a sealing structure is formed between the liquid crystal module and the housing 100, thereby protecting the liquid crystal module 500. Correspondingly, the side wall 120 is provided with a second supporting step 122, the second supporting step 122 is farther from the bottom wall 110 than the first supporting step 121, the second supporting step 122 supports the touch panel 400, and a plane where a side surface 122b of the second supporting step and a top surface 121a of the first supporting step are located forms a second groove capable of accommodating the liquid crystal module 500.
In one embodiment of the present application, the plane size of the liquid crystal module 500 is larger than the plane size of the backlight module 200, and the liquid crystal module 500 includes a central portion facing the backlight module 200 and an edge portion surrounding the central portion and located around the backlight module 200. Preferably, the height difference between the top surface 122a of the second loading step and the top surface 121a of the first loading step in the direction perpendicular to the bottom wall 110 is equal to the sum of the thickness of the liquid crystal module 500 and the thickness of the light shielding member 300; the edge portion of the liquid crystal module 500 is disposed on the top surface 121a of the first loading step. Under the condition that the height difference between the second supporting step 122 and the first supporting step 121 in the direction perpendicular to the bottom wall 110 is equal to the sum of the thickness of the liquid crystal module 500 and the thickness of the light-shielding member 300, the edge portion of the liquid crystal module 500 may be disposed on the first supporting step 121, the first supporting step 121 simultaneously supports the light-shielding member 300 and the liquid crystal module 500, and the second supporting step 122 supports the touch panel 400, so that the assembly stability of the internal structure of the display device is improved.
In one embodiment of the present application, the light shielding member 300 is a light shielding tape having two sides with adhesive properties, and the light shielding tape is attached to the top surface 121a of the first supporting step. Specifically, the light-shielding member 300 is a double-sided adhesive light-shielding tape, the edge portion of the lower surface of the light-shielding tape is attached to the first supporting step 121, and the central portion of the lower surface of the light-shielding tape is attached to the backlight module 200, so that the backlight module 200 is limited while the function of the backlight module 200 is not affected, and the backlight module 200 cannot be separated from the first groove; the upper surface of the light-shielding tape is attached to the liquid crystal module 500. Preferably, the height dimension of the first groove is adapted to the thickness dimension of the backlight module 200, so that the overall structure of the display device arranged in this way is more compact and stable.
In one embodiment of the present application, the sidewall 120 is provided with a wire through hole 123 extending toward the bottom of the sidewall 120 at a position close to the liquid crystal module 500, as shown in fig. 6. In the prior art, the backlight module 200 has a rubber structure, so that gaps exist between the sidewall 120 of the housing 100 and the liquid crystal module 500 and between the sidewall 120 of the housing and the backlight module 200, and cables can pass through the gaps. In the embodiment of the invention, the rubber structure is omitted, and the gap is eliminated, so that the internal structure of the display device is more compact. Therefore, the corresponding position of the side wall 120 is provided with the wire passing hole 123 leading to the bottom of the side wall 120, and the normal passing of the cable is ensured on the premise of not increasing the size of the internal structure.
In order to make the force applied to the light shielding member 300 and the liquid crystal module 500 more uniform, in one embodiment of the present application, the cross section of the first loading step 121 in the direction parallel to the surface of the light shielding member 300 may be annular; similarly, in order to make the stress on the touch panel 400 more uniform, the cross section of the second supporting step 122 in the direction parallel to the surface of the touch panel 400 is annular; the two schemes can be adopted simultaneously, so that the pressure can be dispersed, and the pressure born by the light shielding member 300, the liquid crystal module 500 and/or the touch panel 400 in unit area can be reduced. In some embodiments, the touch panel 400 can be replaced with a decorative panel according to actual conditions or customer requirements. When the touch control function needs to be realized, a touch panel 400 can be superposed above the liquid crystal module 500; when the liquid crystal display panel is only used for screen display of a television and a computer, a decoration panel can be superposed above the liquid crystal module 500, the liquid crystal module 500 can be protected and decorated at the same time, and the decoration panel can be made of acrylic or glass and other materials.
In order to increase the force-bearing area of the light-shielding member 300, the liquid crystal module 500 and/or the touch panel 400, in one embodiment of the present application, the top surface 121a of the first bearing step and/or the top surface 122a of the second bearing step are perpendicular to the sidewall 120. In this way, the top surface of the supporting step can be completely attached to the supported light shielding member 300, the liquid crystal module 500 and the touch panel 400, so that the above components can be easily fixed on the top surface of the supporting step, and the stress is further more uniform.
There are various ways to realize the bearing steps, and the first bearing step 121 and the second bearing step 122 can be separately manufactured and then connected to the inner side of the sidewall 120 by welding or bonding, but this way has problems of time consuming process and insufficient firmness of the connected structure. In one embodiment of the present application, the first supporting step 121 and the sidewall 120 may be integrally formed, the second supporting step 122 and the sidewall 120 may be integrally formed, and the first supporting step 121, the second supporting step 122 and the sidewall 120 may be integrally formed at the same time. And, in order not to cause the redundancy of the bearing steps, the number of the bearing steps is made as required. In addition, for convenience of assembly, the length of the first bearing step 121 in the direction perpendicular to the sidewall 120 is smaller than the length of the second bearing step 122 in the direction perpendicular to the sidewall 120, that is, in the case where there are a plurality of bearing steps, the length of the plurality of bearing steps in the direction perpendicular to the sidewall 120 is gradually increased from the top to the bottom.
In one embodiment of the present application, the touch surface includes an inner side surface facing the bottom wall 110, and the top surface 120a of the sidewall is higher than the inner side surface 410 of the touch panel. The first bearing step 121 limits the degree of freedom of the backlight module 200 in the direction parallel to the bottom wall 110, and the top surface 120a of the side wall limits the degree of freedom of the touch panel 400 and the liquid crystal module 500 fixedly connected with the touch panel 400, so that the backlight module 200, the touch panel 400 and the liquid crystal module 500 are not easy to move relatively; moreover, the top surface 120a of the sidewall higher than the inner surface 410 of the touch panel can also block the gap between the touch panel 400 and the liquid crystal module 500.
In order to meet the strength requirement, the bottom wall 110 of the housing 100 is made of metal, and the side wall 120 is made of plastic, which can reduce the overall weight of the display device.
A second aspect of embodiments of the present invention relates to a mobile terminal including the display device as described above. The mobile terminal in the embodiment of the invention can be a mobile terminal product with a touch function, such as a mobile phone, a notebook computer, a tablet computer and the like.
It will be understood by those of ordinary skill in the art that the foregoing embodiments are specific examples for carrying out the invention, and that various changes in form and details may be made therein without departing from the spirit and scope of the invention in practice.
