Description

Technical Field

[0001] The embodiments of the present application relate to display technology, and more particularly to a touch display device. Background Art

[0002] As a commonly used touch display device, the working principle of the infrared touch screen is to form an infrared grid on the touch panel through an infrared generating tube. When the user touches the touch panel, the input signal can be obtained by obtaining the changes in the infrared grid, thereby confirming the specific location touched by the user.

[0003] As a commonly used touch display device, an infrared touch screen may include a touch display screen, an infrared module and a frame. The frame is arranged at the edge of the touch display screen to fix the touch display screen. The infrared module may be arranged on the inner side of the frame to protect the infrared generating tube through the frame.

[0004] In the related art, in order to improve the structural strength of the frame, the frame adopts an integrated structure design. However, the frame with an integrated structure is not conducive to the installation and maintenance of the infrared module. Specifically, since the frame is an integrated structure and the infrared module is located inside the frame, when an abnormality occurs in the infrared module, it is not easy for the staff to remove the infrared module from the frame. If the frame and the infrared module are replaced together, it is easy to cause cost waste. In addition, the frame with an integrated structure has a certain weight as a whole, which is not conducive to the convenience of assembling the touch screen and the frame. Utility Model Content

[0005] The embodiment of the present application provides a touch display device, which can solve the problem of the integrated frame structure design affecting the installation and maintenance of the infrared module.

[0006] In a first aspect, an embodiment of the present application provides a touch display device, comprising:

[0007] A touch screen display having an operating surface that can be touched by a user;

[0008] A fixed frame assembly, configured to fix the touch display screen, the fixed frame assembly comprising a face frame body and a frame body that are detachably connected, the face frame body being located inside the frame body so as to be detachably connected to the touch display screen, and a receiving cavity being formed between the face frame body and the frame body;

[0009] An infrared module, located in the accommodating cavity, the infrared module comprising a touch lamp, and the touch lamp emits infrared light along a first direction;

[0010] The light guide is located in the accommodating cavity, and the light guide is configured to refract infrared light so that the infrared light emitted along the first direction is switched to be emitted toward the operation surface along the second direction.

[0011] The embodiment of the present application can provide a thin and light touch display device, and can realize easy installation and maintenance of the infrared module. Specifically, the touch display device can fix the touch display screen by a fixed frame assembly. The fixed frame assembly may include a face frame body and a frame body that are detachably connected. The face frame body can be used to be connected to the touch display screen. Since a receiving cavity that can accommodate the infrared module can be formed between the face frame body and the frame body, when an abnormality occurs to the infrared module, the frame body can be disassembled to detect and maintain the infrared module, without having to replace the entire fixed frame assembly and the infrared module.

[0012] Furthermore, since the face frame body and the frame body are detachably connected, the face frame body can be assembled with the touch display screen to form a whole and then connected to the frame body, which helps to reduce the difficulty of installation and avoid the possibility of assembly difficulties caused by the large weight or size of some components.

[0013] In some embodiments of the present application, the light guide is disposed on the inner wall of the frame body, and the light guide is provided with a first inclined surface facing the touch light. The first inclined surface switches the infrared light emitted along the first direction to emitted along the second direction, so that the infrared light is distributed on the operating surface.

[0014] In the embodiment of the present application, a light guide can be provided to change the direction of the infrared light emitted by the infrared module, so that the position of the touch light can be freely set while ensuring that the final path of the infrared light is emitted toward the space on the operating surface. Thus, the position of the touch light does not necessarily need to be above the operating surface, which is conducive to realizing a lightweight design of the touch display device.

[0015] In some embodiments of the present application, the infrared module includes a touch panel, and the touch panel is electrically connected to the touch light;

[0016] The touch panel is arranged on the frame body, and along the second direction, the touch light is located on a side of the touch panel facing the face frame body.

[0017] In the embodiment of the present application, the touch light may be located on a side close to the touch panel to reduce light loss during the process of emitting infrared light to the touch light.

[0018] In some embodiments of the present application, the touch panel has a first end and a second end, and the frame body has corresponding first engaging portions and second engaging portions;

[0019] Wherein, the first end is engaged with the first engaging portion, and / or the second end is engaged with the second engaging portion.

[0021] In some embodiments of the present application, the frame body includes a first frame body, and the first frame body is provided with the first clamping portion; the first clamping portion has a first opening to be configured to accommodate the first end of the touch panel.

[0022] In the embodiment of the present application, the first end of the touch panel can be inserted into the first clamping portion through the first opening, so that the first end of the touch panel is limited by the first clamping portion.

[0023] In some embodiments of the present application, the second engaging portion is disposed on the first frame body and is disposed opposite to the first engaging portion along the first direction;

[0024] The second engaging portion has a first side wall and a second side wall connected to each other, the first side wall is arranged opposite to the face frame body, the second side wall is arranged opposite to the first opening, and the first side wall and the second side wall are configured to limit the touch panel.

[0025] In the embodiment of the present application, since the second side wall and the first side wall form the second engaging portion, and the second side wall is opposite to the first opening, the second side wall is not likely to hinder the second end from being connected to the first side wall during the process of the second end of the touch panel being installed in the second engaging portion. In addition, the second engaging portion is not provided with other structures that hinder the second end from being connected to the second side, and the touch panel can be easily connected to the first side wall, thereby achieving connection with the second engaging portion.

[0026] In some embodiments of the present application, a stop portion is provided on a side of the face frame body facing the first side wall, the stop portion abuts against the touch panel, and the stop portion is configured to limit the touch panel.

[0027] In the embodiment of the present application, the stopper may be provided to constrain the touch panel so that the touch panel is not easily moved along the second direction toward the touch display screen.

[0028] In some embodiments of the present application, the touch display device has a main viewing area, and the frame body is provided with a second inclined surface in the main viewing area.

[0029] In an embodiment of the present application, a second inclined surface can be set on the frame body within the main viewing area to reduce the width of the frame body that can be seen in the main viewing area, so that the frame body has a visual effect of a smaller width in the main viewing area, which is conducive to realizing the narrow-edge design of the touch display device and improving the user experience.

[0030] In some embodiments of the present application, among the plurality of first frames, two adjacent first frames are interference fit;

[0031] The face frame body comprises a plurality of detachably connected second frames, and two adjacent second frames are interference fit.

[0032] In this embodiment, the method of connecting two adjacent first frames by interference fit is simple to operate, and does not require the use of other connecting parts such as locking parts, which can effectively save assembly processes. The method of connecting two adjacent second frames by interference fit is simple to operate, and does not require the use of other connecting parts such as locking parts, which can effectively save assembly processes.

[0057] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, not all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0063] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0064] A touch display device is an inductive liquid crystal display device with a human-computer interaction function. A user can perform touch operations on the touch display device with a finger or a stylus, and the touch display device can respond to the touch operation to obtain the touch point information corresponding to the touch operation and perform corresponding functions according to the touch point information.

[0065] The touch operation may be a click operation, a touch operation, a slide operation, a writing operation, a long press operation, etc. The contact point information may refer to the coordinate information of the action point (contact point) of the touch operation on the touch display device.

[0066] In the related art, the touch light of the infrared module needs to be higher than the surface of the touch panel so that the emitted infrared light is not easily blocked and directly acts on the touch panel, thereby forming an infrared grid in the space on the surface of the touch panel. However, it is easy to understand that if the position of the touch light is higher than the surface of the touch panel, the size of the touch light itself is likely to occupy the space in the thickness direction of the touch display device, making it difficult to achieve a thin and light design of the touch display device.

[0067] The touch display device provided in the embodiment of the present application may be an infrared touch screen. The present application will be described as an infrared touch screen. The touch display device in the embodiment of the present application includes an infrared module and a light guide. The light guide can be used to change the direction of the infrared light emitted by the infrared module. Therefore, the position of the touch light of the infrared module is no longer limited to the surface beyond the touch panel, and the touch light of the infrared module can be arranged at a position that is not easy to occupy the space in the thickness direction of the touch display device, so as to realize the light and thin design of the touch display device.

[0068] The touch display device also includes a touch screen and a frame. The frame is arranged at the edge of the peripheral side of the touch screen to fix the touch screen. The infrared module can be arranged on the inner side of the frame to protect the infrared generating tube through the frame. In order to improve the structural strength of the frame, the frame in the related art usually adopts an integrated structure design. However, the applicant found that the frame with an integrated structure is not conducive to the installation and maintenance of the infrared module. Specifically, since the frame is an integrated structure and the infrared module is located inside the frame, when an abnormality occurs in the infrared module, it is not easy for the staff to remove the infrared module from the frame. If the frame and the infrared module are replaced together, it is easy to cause cost waste. In addition, the frame with an integrated structure has a certain weight as a whole, which is not conducive to the convenience of assembling the touch screen and the frame.

[0069] Based on the above technical problems, the embodiments of the present application can provide a thin and light touch display device, and can realize easy installation and maintenance of the infrared module. Specifically, the touch display device can fix the touch display screen by a fixed frame assembly. The fixed frame assembly may include a face frame body and a frame body that are detachably connected. The face frame body can be used to be connected to the touch display screen. Since a receiving cavity that can accommodate the infrared module can be formed between the face frame body and the frame body, when an abnormality occurs to the infrared module, the frame body can be disassembled to detect and maintain the infrared module, without having to replace the entire fixed frame assembly and the infrared module.

[0070] Furthermore, since the face frame body and the frame body are detachably connected, the face frame body can be assembled with the touch display screen to form a whole and then connected to the frame body, which helps to reduce the difficulty of installation and avoid the possibility of assembly difficulties caused by the large weight or size of some components.

[0071] The touch display device 100 provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0072] In some possible implementations, see Figures 1 to 3 As shown, the touch display device 100 of the embodiment of the present application may include a touch display screen 110 .

[0073] The touch display screen 110 of the embodiment of the present application may have a display function for displaying images, and the touch display screen 110 of the embodiment of the present application may also have a touch function for realizing human-computer interaction.

[0074] For some examples, see Figure 2 and Figure 3 As shown, the touch display screen 110 may include a display module 111. The touch display screen 110 may display images through the display module 111.

[0075] In some examples, the touch display screen 110 may include a touch panel 112. A user may perform touch operations on the touch panel 112. The touch panel 112 may be used to protect the display module 111, and prevent the user from directly touching the display module 111, which may cause the display module 111 to be worn and affect the display effect of the display module 111.

[0076] The touch display screen 110 may have an operation surface that can be touched by the user. The operation surface 112a may be located on the touch panel 112. The user may perform touch operation on the operation surface 112a with a finger or a stylus to interact with the touch display device 100.

[0077] In some possible implementations, see Figure 3 As shown, the touch display device 100 of the embodiment of the present application may include a fixing frame assembly 120. The fixing frame assembly 120 in the embodiment of the present application may be configured to fix the touch display screen 110.

[0078] In some examples, the fixing frame assembly 120 may include a face frame body 121 . The face frame body 121 may be used to fix the touch display screen 110 .

[0079] Exemplarily, the face frame body 121 and the touch display screen 110 may be detachably connected to facilitate installation of the face frame body 121 and the touch display screen 110. For example, the face frame body 121 and the touch display screen 110 may be connected by, but not limited to, snap-fitting or by a locking piece, which is not specifically limited in this embodiment.

[0080] In some examples, the face frame body 121 can be used to fix some connecting wires and other structures in the touch display device 100 .

[0081] For some examples, see Figure 3 As shown, the fixed frame assembly 120 may further include a frame body 122. The face frame body 121 may be located on the inner side of the frame body 122. In other words, the face frame body 121 may be located on the side of the frame body 122 facing the touch display screen 110. The frame body 122 may shield at least a portion of the face frame body 121 to cover structures such as connecting wires disposed on the face frame body 121.

[0082] In some examples, the frame body 122 and the face frame body 121 may be detachably connected. Therefore, during the installation of the touch display device 100 , the face frame body 121 and the touch display screen 110 may be assembled into a whole first, and then connected to the frame body 122 .

[0083] Exemplarily, the frame body 122 may include a first connection portion 1226, and the face frame body 121 may include a second connection portion 1213. The first connection portion 1226 and the second connection portion 1213 may fit each other and be detachably connected via a locking member. When the first connection portion 1226 and the second connection portion 1213 are locked and fit together, the frame body 122 and the face frame body 121 may form a receiving cavity 120a.

[0084] In some examples, a receiving cavity 120 a may be formed between the frame body 122 and the face frame body 121 . Some components may be located in the receiving cavity 120 a , so that the components in the receiving cavity 120 a are protected by the face frame body 121 and the frame body 122 .

[0085] The accommodating cavity 120 a may be used to accommodate electrical components such as connecting wires and the infrared module 130 .

[0086] In some possible implementations, see Figure 3 As shown, the touch display device 100 of the embodiment of the present application may include an infrared module 130. The infrared module 130 may be used to emit infrared light to the touch panel 112 of the touch display screen 110 to form an infrared grid on the operation surface 112a.

[0087] The infrared module 130 may be located in the accommodating cavity 120a. Therefore, when the infrared module 130 fails, the staff may disassemble the frame body 122 to open the accommodating cavity 120a, so that the infrared module 130 may be exposed, so that the staff can conveniently inspect and maintain the infrared module 130.

[0088] In this embodiment, the infrared module 130 can be fixed on any one of the face frame body 121 and the frame body 122. The infrared module 130 can be fixed by, but not limited to, snap connection, adhesive connection, fastener connection, etc., which is not limited in this embodiment.

[0089] In some examples, the infrared module 130 may include a touch light 131. The touch light 131 may be used to emit infrared light. The touch light 131 may emit infrared light along a first direction X.

[0090] In some possible implementations, see Figure 3 As shown, the touch display device 100 may further include a light guide 140. The light guide 140 may be located in the accommodating cavity 120a. The light guide 140 may be configured to refract infrared light.

[0091] In the embodiment of the present application, the light guide 140 can be provided to change the direction of the infrared light emitted by the infrared module 130, so that the position of the touch light 131 can be freely set while ensuring that the final path of the infrared light is emitted toward the space on the operating surface 112a. Thus, the position of the touch light 131 does not necessarily need to be located above the operating surface 112a, which is conducive to realizing a lightweight design of the touch display device 100.

[0092] In some examples, the light guide 140 may have a refractive layer. The infrared light emitted by the touch lamp 131 may be emitted toward the operation surface 112a through the refractive layer of the light guide 140. The inclination angle of the refractive layer on the light guide 140 may be set to adjust the emission direction of the infrared light.

[0093] The number of the light guide member 140 may be one or more. This is not limited in the present embodiment, as long as the infrared light emitted along the first direction X can be switched to be emitted along the second direction Y toward the operation surface 112a.

[0094] In some examples, light guide 140 may be, but is not limited to, a mirrored spacer.

[0095] In some possible implementations, see Figure 3 As shown, the light guide 140 can be disposed on the inner wall of the frame body 122. The light guide 140 can be provided with a first inclined surface 140a facing the touch light 131 to serve as a refraction layer. The first inclined surface 140a can switch the infrared light emitted along the first direction X to the second direction Y, and form an infrared grid on the operation surface 112a. The second direction Y can be distributed parallel to the operation surface 112a.

[0096] In some examples, when the number of the light guide 140 is one, the light guide 140 emits infrared light along the first direction X. The first direction X may be the same as the thickness direction of the touch display device 100. The first direction X may be perpendicular to the second direction Y. At this time, the first inclined surface 140a of the light guide 140 may be inclined at an angle of 45° relative to the operation surface 112a. The infrared light emitted by the touch lamp 131 along the first direction X may be emitted in the second direction Y after being refracted by the first inclined surface 140a at 45°.

[0097] In some possible implementations, the infrared module 130 may include a touch panel 132. The touch panel 132 may be electrically connected to the touch light 131. The touch panel 132 may be used to control the touch light 131 to light up.

[0098] In some examples, the touch panel 132 may be disposed on the frame body 122 . Also, along the second direction Y, the touch light 131 may be located on a side of the touch panel 132 facing the frame body 121 .

[0099] In the embodiment of the present application, the touch light 131 may be located on a side close to the touch panel 112 to reduce light loss during the process of emitting infrared light to the touch light 131 .

[0100] In some examples, the face frame body 121, the frame body 122 and the light guide 140 can provide an emission path for infrared light. The emission path of the infrared light can be that the infrared light emitted by the touch lamp 131 is emitted in the first direction X toward the first inclined surface 140a of the light guide 140, and at the first inclined surface 140a, the infrared light can be refracted to be emitted in the second direction Y to the operating surface 112a of the touch panel 112. It is easy to understand that there is no shielding on the emission path to ensure that the infrared light is not easily blocked and affects the emission direction.

[0101] In some examples, the touch light 131 can be close to the touch panel 112 along the first direction X to reduce light loss during the refraction of infrared light. Specifically, in an ideal state, the infrared light emitted by the touch light 131 can all be emitted toward the first inclined surface 140a along the first direction X, and the first inclined surface 140a can emit all infrared light along the second direction Y to act on the operating surface 112a.

[0102] In some examples, the light guide 140 may have a first inclined surface 140a to refract the infrared light through the first inclined surface 140a. Alternatively, the light guide 140 may be a flat plate structure, and the light guide 140 may be disposed on the inclined wall surface of the frame body 122. This is not limited in this embodiment.

[0103] In some examples, the touch display device 100 may include a filter 150. The filter 150 may filter the infrared light before the infrared light is emitted to the display surface.

[0104] In some possible implementations, see Figure 3 and Figure 4 As shown, along the first direction X, the touch panel 132 may have a first end 1321 and a second end 1322 . The frame body 122 is provided with a first engaging portion 1221 corresponding to the first end 1321 .

[0105] The first end 1321 and the first engaging portion 1221 may be engaged with each other.

[0106] In some examples, the frame body 122 may also be provided with a second engaging portion 1222 corresponding to the second end 1322. The second end 1322 and the second engaging portion 1222 may engage with each other.

[0107] In the embodiment of the present application, the touch panel 132 can be initially positioned by engaging the first end 1321 with the first engaging portion 1221 or engaging the second end 1322 with the second engaging portion 1222. Alternatively, the touch panel 132 can be fixed by engaging the first end 1321 with the first engaging portion 1221 and the second end 1322 with the second engaging portion 1222.

[0108] In some possible implementations, see Figure 4 and Figure 5 As shown, the frame body 122 may include a first frame body 1223. A first engaging portion 1221 is disposed on the first frame body 1223. The first engaging portion 1221 has a first opening 1221a to accommodate the first end 1321 of the touch panel 132.

[0109] In the embodiment of the present application, the first end 1321 of the touch panel 132 can be inserted into the first engaging portion 1221 through the first opening 1221 a , so that the first end 1321 of the touch panel 132 is limited by the first engaging portion 1221 .

[0110] In some examples, the first engaging portion 1221 may be a groove structure. The first engaging portion 1221 may have a first limiting wall 12211 and a second limiting wall 12212 that are opposite to each other along the second direction Y, so as to limit the first end 1321 of the touch panel 132 along the second direction Y, thereby maintaining the connection stability between the touch panel 132 and the frame body 122. The bottom wall of the first engaging portion 1221 is opposite to the first opening 1221a.

[0111] In some examples, there may be a plurality of first frames 1223. The plurality of first frames 1223 may be detachably connected.

[0112] In some possible implementations, see Figure 4 and Figure 5 As shown, the second engaging portion 1222 can be disposed on the first frame body 1223, and is disposed opposite to the first engaging portion 1221 along the first direction X. The second engaging portion 1222 can have a second side wall 12222 and a first side wall 12221 connected to each other. The second side wall 12222 is disposed opposite to the first opening 1221a. The first side wall 12221 is disposed opposite to the face frame body 121, and the second side wall 12222 and the first side wall 12221 are configured to limit the touch panel 132.

[0113] In the embodiment of the present application, since the second side wall 12222 and the first side wall 12221 form the second engaging portion 1222, and the second side wall 12222 is opposite to the first opening 1221a, the second side wall 12222 is not likely to hinder the second end 1322 from being connected to the first side wall 12221 during the process of the second end 1322 of the touch panel 132 being installed in the second engaging portion 1222. In addition, the second engaging portion 1222 is not provided with other structures that hinder the second end 1322 from being connected to the second side, and the touch panel 132 can be easily connected to the first side wall 12221, thereby achieving connection with the second engaging portion 1222.

[0114] Specifically, see Figure 5 and Figure 6 As shown, the installation process of the touch panel 132 and the frame body 122 can be as follows. The first end 1321 of the touch panel 132 can be inserted into the first engaging portion 1221 to initially limit the first end 1321 of the touch panel 132. Then, the second end 1322 of the touch panel 132 can be rotated relative to the first end 1321 so that the second end 1322 of the touch panel 132 can abut against the first side wall 12221.

[0115] The first side wall 12221 can restrict the touch panel 132 from moving along the second direction Y in a direction away from the touch display screen 110 .

[0116] In some possible implementations, see Figure 3 and Figure 4 As shown, a stopper 1211 may be provided on one side of the face frame body 121 facing the first side wall 12221. The stopper 1211 may abut against the touch panel 132. The stopper 1211 is configured to limit the touch panel 132.

[0117] In the embodiment of the present application, the stopper 1211 can be provided to constrain the touch panel 132 so that the touch panel 132 is not easy to move along the second direction Y toward the touch display screen 110 .

[0118] In some examples, the first side wall 12221 and the first limiting wall 12211 may be located in the same plane. The first side wall 12221 may be used to constrain the first end 1321 of the touch panel 132 from moving in the second direction Y in a direction away from the touch display screen 110. The first limiting wall 12211 may be used to constrain the second end 1322 of the touch panel 132 from moving in the second direction Y in a direction away from the touch display screen 110. Therefore, the first side wall 12221 and the first limiting wall 12211 may prevent the touch panel 132 from moving in a direction away from the touch display screen 110.

[0119] Furthermore, the second limiting wall 12212 can be used to restrict the first end 1321 of the touch panel 132 from moving toward the touch display screen 110 along the second direction Y. The stopper 1211 can also be used to restrict the touch panel 132 from moving toward the touch display screen 110. Therefore, the second limiting wall 12212 and the stopper 1211 can prevent the touch panel 132 from moving toward the touch display screen 110.

[0120] For some examples, see Figure 7 and Figure 8 As shown, the infrared module 130 can be connected to the frame body 122 to form a whole. The face frame body 121 can be connected to the touch display screen 110 to form a whole, and then connected to the face frame body 121 through the frame body 122 to achieve a fixed connection between the above two bodies.

[0121] In some possible implementations, see Figure 1 and Fig. 9 As shown, the touch display device 100 may have a main viewing area. The main viewing area may refer to an area that a user can see when facing the touch display screen 110 of the touch display device 100 .

[0122] It is easy to understand that the width of the frame body 122 can affect the user's visual effect when the user looks directly at the touch display device 100. The smaller the width of the frame body 122, the better the user's visual experience. On the contrary, the larger the width of the frame body 122, the worse the user's visual experience.

[0123] Therefore, in the examples of this application, see Fig.10 and Fig.11 As shown, a second inclined surface 122a can be set on the frame body 122 within the main viewing area to reduce the width of the frame body 122 that can be seen in the main viewing area, so that the frame body 122 can have a visual effect of a smaller width in the main viewing area, which is conducive to realizing a narrow-edge design of the touch display device 100 and improving the user experience.

[0124] In some examples, the second inclined surface 122 a may correspond to the first inclined surface 140 a of the light guide 140 .

[0125] In some possible implementations, see Fig.12 As shown, in the plurality of first frames 1223 in the embodiment of the present application, two adjacent first frames 1223 may be interference-fitted with each other.

[0126] In this embodiment, the method of connecting two adjacent first frames 1223 by interference fit is simple to operate and does not require the use of other connecting parts such as locking parts, which can effectively save assembly steps.

[0127] In some examples, one of the two adjacent first frames 1223 may be provided with a protrusion 1224, and the other first frame 1223 may be provided with a recess 1225 corresponding to the protrusion 1224. The protrusion 1224 is inserted into the recess 1225, and the protrusion 1224 and the recess 1225 are interference-fitted to achieve a fixed connection between the two first frames 1223.

[0128] In some examples, the touch display screen 110 may be a square structure. The number of the first frame bodies 1223 may be four. The four first frame bodies 1223 may be arranged along four edges of the touch display screen 110 .

[0129] It should be noted that the lengths of the plurality of first frames 1223 may not be completely equal. For example, when the touch display screen 110 is a rectangular structure, the lengths of two of the four first frames 1223 may be greater than the lengths of the other two first frames 1223 .

[0130] In some achievable embodiments, the face frame body 121 may include a plurality of detachably connected second frames 1212. Two adjacent second frames 1212 may be interference-fitted.

[0131] In this embodiment, the two adjacent second frames 1212 are connected by interference fit, which is simple to operate and does not require other connecting parts such as locking parts, thereby effectively saving assembly steps.

[0132] In some examples, one of the two adjacent second frames 1212 may be provided with a protrusion 1224, and the other second frame 1212 may be provided with a recess 1225 corresponding to the protrusion 1224. The protrusion 1224 is inserted into the recess 1225, and the protrusion 1224 and the recess 1225 are interference-fitted to achieve a fixed connection between the two second frames 1212.
