Referring to fig. 1 to 5, the display screen includes a display screen touch frame structure, the display screen touch frame structure further includes a touch frame assembly 1 disposed on a side of the display screen, and the touch frame assembly 1 specifically includes:

the display device comprises a frame body 11, a first frame edge 1111 and a second frame edge 1121, wherein the frame body 11 and the display screen are fixed with each other and are provided with a first frame edge 1111 and a second frame edge 1121 which extend to the outside of the light-emitting side of the display screen and are sequentially arranged along the light-emitting direction;

a touch module 12, where the touch module 12 includes a filter strip 121, and the filter strip 121 is disposed between the first frame edge 1111 and the second frame edge 1121 and configured to be fixed to the second frame edge 1121 through the first adhesive layer 6;

the end surface of the first frame rim 1111 facing the filter strip 121 abuts against the filter strip 121, so as to cooperate with the second frame rim 1121 to clamp the filter strip 121 and the first adhesive layer 6.

In the solution provided in this embodiment, please refer to fig. 4, the first frame edge 1111 and the second frame edge 1121 are mainly used for matching with the first adhesive layer 6, so that the filter strip 121 can be fixed without reserving a groove thickness on the frame edge and processing a clamping block matched with the thickness, and the filter strip 121 is fixed more firmly without loosening due to an assembly error. The frame body 11 and the display screen are fixed to each other, and specifically, the frame body 11 is fixed to the periphery of the display screen to wrap the periphery of the display screen. First frame 1111 and second frame 1121 extend to the display screen light-emitting side and arrange along the light-emitting direction in proper order outside, and the filter strip 121 sets up between first frame 1111 and second frame 1121 for the filter strip 121 must be outside the display screen light-emitting side, guarantees that follow-up touch module 12 when carrying out infrared positioning through the infrared light, and the filter strip 121 can play corresponding filtering effect. For the fixing of the filter strip 121, two manners are mainly used for matching and fixing in this embodiment, first, the filter strip 121 is directly fixed on the second frame edge 1121 by using the first adhesive layer 6 to achieve a primary fixing, where the first adhesive layer 6 may be glue, a double-sided tape, or another adhesive layer capable of adhering two objects together; secondly, the end surface of the first rim 1111 is abutted against the end surface of the filter strip 121 away from the first adhesive layer 6, and then the first rim 1111 and the second rim 1121 are matched to form a synchronous clamping for the filter strip 121 and the first adhesive layer 6, and the first adhesive layer 6 and the filter strip 121 are respectively contacted with the filter strip 121 and the second rim 1121 more tightly by applying a clamping force to the first adhesive layer 6 and the filter strip 121 by using the first rim 1111 and the second rim 1121, so that the filter strip 121 is bonded to the second rim 1121 more firmly, thereby realizing low assembly precision and fixing the filter strip 121 without reserving thickness.

In the solution provided in this embodiment, a portion of the filter strip 121 playing a role of filtering extends to the light emitting surface of the glass cover plate 2 of the display screen, and an end surface of the portion departing from the first frame edge 1111 contacts with the glass cover plate 2. The filter strip 121 and the second frame edge 1121 form an integral enclosure to form a bayonet 114 for the edge of the glass cover plate 2 to be clamped in, one end surface of the bayonet 114 is an end surface of the filter strip 121 departing from the first frame edge 1111 and contacting with the glass cover plate 2, the other end surface of the bayonet is the second frame edge 1121, specifically, the second frame edge 1121 includes a first end surface and a second end surface, the end surface forming the bayonet 114 is the second end surface, that is, the second end surface and the filter strip 121 depart from the first frame edge 1111 and extend to the end surface of the light emitting surface of the display screen glass cover plate 2 to form the bayonet 114, and the glass cover plate 2 is clamped in the bayonet 114. The second end face is further provided with a second adhesive layer 7, and the glass cover plate 2 is adhered to the second end face through the second adhesive layer 7, so that the glass cover plate 2 is fixed on the second frame edge 1121 through the second adhesive layer 7, and the abutting pressure applied to the light filter strip 121 is transmitted to the glass cover plate 2, thereby further assisting in fixing the glass cover plate 2. Here, the second adhesive layer 7 is a VHB paste layer.

Furthermore, the first end face and the second end face are arranged in a staggered manner in the direction towards the first frame edge 1111, the first end face and the second end face integrally form a step shape, and a part of limiting face connected with the first end face and the second end face is formed; for the light filtering strip 121, the portion of the light filtering strip 121 extending to the light emitting surface of the display screen glass cover plate 2 and the portion of the light filtering strip 121 fixed on the first end surface through the first adhesive layer 6 are also arranged in a staggered manner, and similarly, a partial limiting surface is formed, the partial limiting surface on the light filtering strip 121 and the partial limiting surface on the second frame edge 1121 jointly form a complete limiting surface, the limiting surface belongs to a part of the bayonet 114, when the glass cover plate 2 is clamped into the bayonet 114, the side wall of the edge of the glass cover plate 2 is attached to the limiting surface, so that the glass cover plate 2 is further limited from moving in the direction perpendicular to the second end surface, and the glass cover plate 2 is more stably fixed.

In the solution provided in this embodiment, referring to fig. 2 and fig. 4, the touch module 12 further includes a touch PCB assembly 122, an accommodating space 115 for accommodating the touch PCB assembly 122 is enclosed in the frame 11, the touch PCB assembly 122 is disposed in the accommodating space 115 and is adhered to an inner wall of the accommodating space 115 through a third adhesive layer 8, where the third adhesive layer 8 may be glue, a double-sided adhesive, or another adhesive layer capable of adhering two objects together. The touch PCB assembly 122 has a function of emitting and receiving infrared rays, and forms an infrared detection net on the surface of the glass cover 2, and any touch object can change the infrared rays on the touch points to implement touch screen operation, and the principle thereof is similar to surface acoustic wave touch, and the touch object (e.g. finger) can change the infrared rays of an electric shock and then be converted into a coordinate position of touch to implement operation response. The touch PCB assembly 122 is fixed on the inner wall of the accommodating space 115 by adhesion, so that the installation process can be simplified, and the surface of the touch PCB assembly 122 and the inner wall of the accommodating space 115 are not damaged.

It should be noted that, in other embodiments, the touch PCB assembly 122 may be fixed on the inner wall of the accommodating space 115 by using a conventional relatively mature fastening method such as clamping, screwing, or the like.

Further, the touch PCB assembly 122 of the present embodiment includes an infrared transmitting and receiving sensing element 1222 and a PCB 1221 disposed outside the side portion of the light filter strip 121. The infrared transmitting and receiving sensing element 1222 is internally provided with an infrared transmitting tube and an infrared receiving tube for respectively transmitting and receiving infrared light by the infrared transmitting and receiving sensing element 1222. The infrared transmitting and receiving sensing element 1222 is electrically connected to the PCB 1221, so as to transmit infrared information into the PCB 1221 and make corresponding feedback actions. The light filter strip 121 is disposed on the light input and output side of the infrared transmitting and receiving sensor 1222 to filter light, and a recess is formed between the portion of the light filter strip 121 contacting the first end surface and the portion of the light filter strip 121 contacting the second end surface, the recess is used as an avoidance space, and the infrared transmitting and receiving sensor 1222 extends at least partially into the avoidance space, specifically, how much into the avoidance space, which is determined by the length of the avoidance space in the light output direction of the infrared transmitting and receiving sensor 1222 and the length of the infrared transmitting and receiving sensor 1222 itself. The light-filtering strip 121 is recessed to form an avoiding space, so that the infrared transmitting and receiving sensing element 1222 can be placed in the avoiding space, and the width of the accommodating space 115 in the light emitting direction of the infrared transmitting and receiving sensing element 1222 is reduced, so that the thickness of the whole touch frame assembly 1 is reduced, and the internal structure of the accommodating space 115 is more compact.

It should be noted that, as can be seen from the above description, the infrared transmitting and receiving sensing element 1222 is located between the second frame border 1121 and the first frame border 1111, and in order to ensure that the infrared transmitting and receiving sensing element 1222 is not pressed by the first frame border 1111 and the second frame border 1121, the height of the filter strip 121 towards the first frame border 1111 is higher than the height of the infrared transmitting and receiving sensing element 1222 towards the first frame border 1111, so that the first frame border 1111 only abuts against the filter strip 121, and a certain gap exists between the first frame border 1111 and the infrared transmitting and receiving sensing element 1222 to protect the infrared transmitting and receiving sensing element 1222 from being damaged by the first frame border 1111.

In the solution provided in this embodiment, the frame 11 may be integrally formed, and the first frame edge 1111 and the second frame edge 1121 are respectively formed inside the frame; the housing 11 may be divided into two independent portions. With the integrally molded structure, it is more difficult to produce and mount than a structure composed of two separate parts, so the frame body 11 in this embodiment includes the outer frame 111 formed with the first frame rim 1111 and the middle frame 112 formed with the second frame rim 1121. Referring to fig. 4, the outer frame 111 is U-shaped and has an opening facing the display module of the display screen, and the middle frame 112 is accommodated in the opening. The middle frame 112 is arranged outside the side portion of the display module on the side away from the outer frame 111, the middle frame 112 is fixed on the back plate 3 of the display screen through bolts, the other frame side of the outer frame 111, which is arranged opposite to the first frame side 1111, is also fixed on the back plate 3 through bolts, the frame side is located outside the back plate 3, and the middle frame 112 is located inside the back plate 3, so that the middle frame 112 and the outer frame 111 are fixed.

It should be noted that the display module mentioned above refers to various components in the display screen, such as a display panel, a rubber frame, some optical elements, and so on, and is not described in detail since it is the prior art and is unrelated to the technical problem solved by the present solution; in addition, the connection and composition relationship among the glass cover plate 2, the back plate 3 and the display module also belongs to the prior art, and is not described in detail.

For the display screen back plate 3, it extends to the middle frame 112 outside one side opposite to the light filtering strip 121, and the middle frame 112 is fixed on the back plate 3 extending to the middle frame 112 outside one side opposite to the light filtering strip 121 through the bolt, and the end edge of the back plate 3 is bent to form the bending part 31 extending to the middle frame 112 outside one side opposite to the display module, the inner wall of the bending part 31 contacts with the outer wall of one side of the middle frame 112, and one side wall of the middle frame 112 departing from the bending part 31 contacts with the display module, i.e. the middle frame 112 is located between the bending part 31 and the display module and is limited and positioned by the display module and the bending part 31, so that the middle frame 112 can be directly and accurately placed into the corresponding position of the back plate 3 when being installed, and is directly fixed through the bolt, and the installation process is simplified. The outer frame 111 encloses the edges of the display screen and the middle frame 112, so as to prevent the middle frame 112 and some parts of the display screen from being directly exposed to the outside, and damage or dust can enter.

For the middle frame 112, it should be further described that the third adhesive layer 8 is disposed on a side of the middle frame 112 away from the display module, the PCB 1221 is fixed on a side of the middle frame 112 away from the display module through the third adhesive layer 8, and the middle frame 112 is further provided with a limiting groove 116, one end of the PCB 1221 away from the infrared emission and reception sensing element 1222 is inserted into the limiting groove 116, so as to further fix the PCB 1221, and also play a role in positioning and mounting the PCB 1221, thereby accelerating the mounting progress.

Referring to fig. 3, four touch frame components 1 are provided to match four sides of the display screen, and adjacent touch frame components 1 are connected by corner pieces 5, specifically, the corner pieces 5 are respectively contacted with the middle frames 112 of two adjacent touch frame components 1, and two ends of the corner pieces 5 are respectively locked to the middle frames 112 of two adjacent touch frame components 1 by screws, so as to realize the connection and fixation between two adjacent touch components.

Example 2

Referring to fig. 5, the main body of embodiment 2 is also a display screen, and the solution provided by embodiment 2 is substantially the same as that provided by embodiment 1, and the main difference between the two is the way and structure of fixing the middle frame 112 and the outer frame 111 on the display screen. In this embodiment, the touch frame assembly 1 further includes a connecting bracket 4 fixed on the display module, in addition to the frame 11 and the filter strip 121, the connecting bracket 4 is L-shaped, a portion of the connecting bracket 4 is fixed on the display module by using bolts, or other fixing methods, without limitation, and another portion of the connecting bracket is bent and extended to conform to the outline of the display module until the connecting bracket extends to the outside of the outer frame 111. For the middle frame 112, a part of the middle frame 112 also extends to the outside of the outer frame 111 and is adjacent to and in contact with the part of the connecting bracket 4 extending to the outside of the outer frame 111, and then the adjacent part is locked by screws, thereby achieving the purpose of fixing the middle frame 112 on the display screen. Further, the outer frame 111 is attached to the middle frame 112 by screws. In the embodiment, the middle frame 112 is fixed by using the connecting bracket 4, instead of directly using the back plate 3, so as to adapt to the flexible circuit board being folded to the back plate 3 side, and if the middle frame 112 is directly fixed on the back plate 3, the folding of the flexible circuit board will be affected.
