[0068] As described in the background technology, in the related art, the touch display device includes a frame, a lower front shell and a touch film layer, wherein the lower front shell can be installed below the frame, and the touch film layer can be installed on the front side of the frame, so that the lower front shell and the touch film layer can be fixed by the frame. However, as the touch modes of the touch display device are diversified, for example, the touch display device can include a capacitive touch display device and an infrared touch display device, etc., the frame cannot be used to form a touch display device with different touch modes, so that the application range of the frame is small and the interchangeability of the frame is poor.

[0069] In view of this, the touch display device of the embodiment of the present application includes a frame with a mounting structure and a lower front shell. The frame can be connected to the upper front shell and the first touch element through the mounting structure, and the lower front shell can be used to connect the second touch element, thereby making the functions of the frame and the lower front shell richer.

[0070] When the touch display device is a capacitive touch display device, the mounting structure is not connected to the upper front shell and the first touch element, and the lower front shell is not provided with a second touch element. In addition, the cover assembly may include a capacitive touch film layer, which is at least used to obtain the user's click position, so that the touch process of the touch display device can be realized through the capacitive touch film layer.

[0071] Alternatively, the touch display device is an infrared touch display device, the mounting structure connects the upper front shell and the first touch element, the lower front shell is provided with a second touch element, the first touch element and the second touch element cooperate to obtain the user's click position, thereby enabling the touch process of the touch display device to be realized through the first touch element and the second touch element.

[0072] Compared with the frame of the touch display device in the related art, the touch display device in the embodiment of the present application is provided with a frame having a mounting structure, and can connect the upper front shell and the first touch element through the mounting structure, and connect the second touch element through the lower front shell, so that the frame can be suitable for capacitive touch display devices and infrared touch display devices, thereby increasing the scope of use of the frame and improving the versatility and interchangeability of the frame.

[0073] Furthermore, since the lower front shell can at least be used to accommodate the wiring of structures such as the display panel and the cover assembly, the lower front shell can also be used to install structures such as buttons, so that the touch display device can be controlled through the buttons and other structures located on the lower front shell, making the functions of the lower front shell more abundant.

[0080] 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.

[0081] Reference Figure 1-Figure 3An embodiment of the present application provides a touch display device, including a frame 100 and a display panel 200. The frame 100 may include an upper frame 110 and a lower frame 120 arranged opposite to each other in a vertical direction, and the frame 100 may include a left frame 130 and a right frame 140 arranged opposite to each other in a horizontal direction.

[0082] The upper frame 110 , the lower frame 120 , the left frame 130 and the right frame 140 may be arranged to form a square structure, wherein the upper frame 110 and the lower frame 120 may extend in the horizontal direction, and the left frame 130 and the right frame 140 may extend in the vertical direction.

[0083] The display panel 200 may be disposed inside the frame 100. Alternatively, the display panel 200 may be disposed on the rear side of the frame 100. The light-emitting side of the display panel 200 may face the front side of the frame 100, so that the frame 100 can provide certain support and protection for the display panel 200.

[0084] The touch display device may have a top side and a bottom side that are arranged opposite to each other, and a left side and a right side that are arranged opposite to each other.

[0085] When the touch display device is placed in a vertical direction, the sky side of the touch display device can be set as the side of the touch display device facing upward, the ground side of the touch display device can be set as the side of the touch display device facing downward, the left side of the touch display device can be set as the side of the touch display device facing left, and the right side of the touch display device can be set as the side of the touch display device facing right.

[0086] It is easy to understand that the upper frame 110 can be located on the top side of the touch display device, the lower frame 120 can be located on the bottom side of the touch display device, the left frame 130 can be located on the left side of the touch display device, and the right frame 140 can be located on the right side of the touch display device.

[0087] Reference Figure 3 In some possible implementations, the touch display device may include a cover assembly 300. The cover assembly 300 may be disposed on the front side of the frame 100, and the cover assembly 300 may be disposed parallel to and opposite to the display panel 200.

[0088] The cover assembly 300 is fixedly connected to at least one of the upper frame 110, the lower frame 120, the left frame 130 and the right frame 140, so that the display panel 200 can be protected by at least the cover assembly 300, reducing the possibility of damage to the display panel 200.

[0089] For example, refer to Figure 4 and Figure 5The touch display device may include a lower front shell 400. The lower front shell 400 may be fixedly disposed on a side of the lower frame 120 away from the upper frame 110, and the lower front shell 400 may at least be used to accommodate the wiring of structures such as the display panel 200 and the cover assembly 300.

[0090] The lower front shell 400 can also be used to install structures such as buttons, so that the touch display device can be controlled through the structures such as buttons located on the lower front shell 400, making the functions of the lower front shell 400 more abundant.

[0091] In some possible implementations, the frame 100 may be configured as an integrated structure, so that the structure of the frame 100 is more stable, and the possibility of deformation of the frame 100 is reduced.

[0092] At least two of the upper frame 110, the lower frame 120, the left frame 130 and the right frame 140 that are connected can be set as an integrated structure, so there is no need to connect the upper frame 110, the lower frame 120, the left frame 130 and the right frame 140 in sequence, making the splicing and assembly process of the frame 100 more convenient.

[0093] Alternatively, the frame 100 can be formed by splicing or the like, so that the upper frame 110, the lower frame 120, the left frame 130 and the right frame 140 can all be prepared and transported separately, thereby making the preparation process of the frame 100 more convenient and reducing the possibility of the frame 100 being squeezed and deformed during transportation.

[0094] Reference Figure 6 and Figure 7 In some possible implementations, the upper frame 110 may be provided with a mounting structure 111, and the mounting structure 111 may at least be reused to connect the upper front shell 500 and the first touch element 600, so as to enrich the functions of the upper frame 110.

[0095] For example, refer to Figure 1-Figure 3 The left frame 130 can be reused to connect at least the left front shell and one of the first touch element and the second touch element. The right frame 140 can be reused to connect at least the right front shell and the other of the first touch element and the second touch element.

[0096] Reference Figure 8 and Fig. 9 In some possible implementations, the lower front shell 400 may be provided with a lower accommodating cavity 410 .

[0097] The lower accommodating cavity 410 is at least used to accommodate the second touch element 700, so that the functions of the lower front shell 400 are more abundant, and the installation process of the first touch element 600 and the second touch element 700 can be realized through the upper frame 110 and the lower front shell 400. The lower accommodating cavity 410 has a lower opening, which is located on the side of the cover assembly 300 away from the frame 100, and the lower opening faces the upper frame 110.

[0098] The lower front housing 400 can at least accommodate wiring of structures such as the display panel 200 and the cover assembly 300 .

[0099] The cavity of the lower front shell 400 for accommodating the above-mentioned wiring can be reused to form the lower accommodating cavity 410, that is, the lower accommodating cavity 410 can accommodate the second touch element 700 and the wiring, etc. at the same time, thereby making the structure of the lower front shell 400 simpler and the preparation of the lower front shell 400 more convenient.

[0100] Reference Figure 6 and Figure 8 When the touch display device is an infrared touch display device, the mounting structure 111 connects the upper front shell 500 and the first touch element 600, and the lower front shell 400 is provided with the second touch element 700. The first touch element 600 and the second touch element 700 cooperate with each other to obtain the user's click position, so that the touch process of the touch display device can be realized through the first touch element 600 and the second touch element 700.

[0101] The left frame 130 can be connected to the left front shell and one of the first touch element 600 and the second touch element 700, and the right frame 140 can be connected to the right front shell and the other of the first touch element 600 and the second touch element 700, so that the touch process of the infrared touch display device can be realized through the first touch element 600 and the second touch element 700 located in the left front shell and the right front shell, making the touch process of the infrared touch display device more accurate and improving the touch accuracy of the infrared touch display device.

[0102] Reference Figure 8 and Fig. 9 For example, the lower front shell 400 may be located below the lower frame 120 , and the lower front shell 400 may include an abutment portion 420 . The abutment portion 420 may be located on a side of the lower frame 120 away from the upper frame 110 , and the abutment portion 420 may abut the cover assembly 300 and the lower frame 120 .

[0103] When the lower front shell 400 and the lower frame 120 are fixed to each other, the abutment portion 420 of the lower front shell 400 can be abutted against the cover assembly 300 and the lower frame 120, so that the abutment portion 420 of the lower front shell 400 can play a certain positioning and limiting role, and the abutment portion 420 of the lower front shell 400 can reduce the possibility of displacement and movement of the cover assembly 300.

[0104] And / or, the lower front case 400 may include a connection portion 430. The connection portion 430 may extend toward the upper frame 110. The connection portion 430 may be provided with at least one fixing member, and the connection portion 430 may be connected to the lower frame 120 through the fixing member.

[0105] When fixing the lower front shell 400 and the lower frame 120 to each other, the connecting portion 430 of the lower front shell 400 can be fixedly connected to the lower frame 120 through a fixing member, so that the connection between the lower front shell 400 and the lower frame 120 can be more stable, reducing the possibility of the lower front shell 400 detaching from the lower frame 120.

[0106] The fixing member can be set as a fixing bolt. When fixing the lower front shell 400 and the lower frame 120 to each other, the fixing bolt can be passed through the connecting portion 430 of the lower front shell 400, and the threaded section of the fixing bolt can be threadedly connected to the lower frame 120, so that the connecting portion 430 of the lower front shell 400 and the lower frame 120 can be relatively fixed by the fixing bolt.

[0107] The number of the fixing bolts can be set to one or more. When the number of the fixing bolts is set to multiple, the multiple fixing bolts can be arranged in sequence and spaced apart in the horizontal direction, so that the connection between the lower front shell 400 and the lower frame 120 is more stable.

[0108] For example, the lower front case 400 may be provided with an extension portion 440 . One end of the extension portion 440 that is away from the lower front case 400 may extend toward the upper frame 110 .

[0109] The extension portion 440 may abut against the surface of the cover assembly 300 away from the frame 100, and the extension portion 440 forms at least a portion of the lower accommodation cavity 410. The lower opening may be provided at one end of the extension portion 440 facing the upper frame 110.

[0110] It is easy to understand that the extension portion 440 abuts against the surface of the cover assembly 300 facing away from the frame 100, and the extension portion 440 forms at least a portion of the lower accommodating cavity 410, so that the second touch element 700 can be set in the extension portion 440, and the second touch element 700 can be located on the surface of the cover assembly 300 facing away from the frame 100.

[0111] When the touch display device is configured as an infrared touch display device, the second touch element 700 can send or receive a signal at a side of the cover assembly 300 away from the frame 100 , so that the second touch element 700 can face the first touch element 600 .

[0112] In some possible implementations, the touch display device may be configured as a capacitive touch display device.

[0113] Exemplarily, the mounting structure 111 is not connected to the upper front shell 500 and the first touch element 600, and the lower front shell 400 is not provided with the second touch element 700. The upper frame 110 with the mounting structure 111 and the lower front shell 400 can be used to form a capacitive touch display device, and the upper surface of the upper frame 110 away from the lower frame 120 can form the upper surface of the capacitive touch display device.

[0114] The surface of the left frame 130 facing away from the right frame 140 can form the left side of the capacitive touch display device, and the surface of the right frame 140 facing away from the left frame 130 can form the right side of the capacitive touch display device. Neither the left frame 130 nor the right frame 140 needs to be connected to other structures, so that the frame 100 can be used to form a capacitive touch display device.

[0115] Exemplarily, the cover assembly 300 may include a capacitive touch film layer, which is used at least to obtain a click position of a user, so that a touch control process of a touch display device can be realized through the capacitive touch film layer.

[0116] It is easy to understand that the capacitive touch film layer can have a touch layer and a sensing layer arranged in parallel and opposite to each other, so that the user's click position and click force can be obtained through the matching touch layer and sensing layer, and a corresponding electrical signal can be formed to output the above electrical signal to the controller of the touch display device.

[0117] The cover plate assembly 300 may also include a cover plate, and the cover plate and the capacitive touch film layer may be fixed by bonding or the like. The cover plate assembly 300 may be bonded and fixed to the front side of the frame 100 by the bonding layer 310, so that the capacitive touch film layer is protected to a certain extent by the cover plate, and the possibility of deformation of the capacitive touch film layer is reduced.

[0118] In some possible implementations, the touch display device may be configured as an infrared touch display device.

[0119] Reference Fig.10 and Fig.11 Exemplarily, the infrared touch display device may include an upper front shell 500, which may be fixedly connected to the mounting structure 111, so that the upper front shell 500 can be connected through the mounting structure 111 of the upper frame 110, so that the functions of the upper frame 110 are more abundant.

[0120] The upper front shell 500 may be provided with an upper accommodating cavity 510. The upper accommodating cavity 510 may be provided with an upper opening, and the upper opening may face the lower opening. The upper opening may face downward, and the lower opening may face upward. The upper opening may be arranged opposite to the lower opening, so as to realize the emission and sensing process of infrared light through the upper opening and the lower opening.

[0121] Reference Figure 8 , Fig.10 and Fig.11 For example, the infrared touch display device may include a touch component. The touch component may include a first touch element 600 and a second touch element 700 that cooperate with each other.

[0122] One of the first touch element 600 and the second touch element 700 may be used to emit infrared light, and the other of the first touch element 600 and the second touch element 700 may be used to sense infrared light.

[0123] The first touch element 600 may be disposed in the upper accommodation cavity 510. The functional end of the first touch element 600 may be directed toward the second touch element 700 through the upper opening. The second touch element 700 may be disposed in the lower accommodation cavity 410, and the functional end of the second touch element 700 may be directed toward the first touch element 600 through the lower opening, so as to achieve mutual cooperation between the first touch element 600 and the second touch element 700.

[0124] For example, the first touch element 600 can be used to emit infrared light. The first touch element 600 can extend in the horizontal direction, and the first touch element 600 can emit a plurality of infrared light rays sequentially arranged in the horizontal direction. The second touch element 700 can extend in the horizontal direction, and the second touch element 700 can be used to sense infrared light.

[0125] The touch display device is configured as an infrared touch display device. When the touch process of the infrared touch display device is implemented by the matching first touch element 600 and second touch element 700, the first touch element 600 can emit infrared light downward through the upper opening, and the second touch element 700 can receive infrared light from the first touch element 600 through the lower opening.

[0126] When the user clicks on the cover assembly 300, the user's finger or stylus will block and intercept the infrared light from the first touch element 600, so that at least part of the second touch element 700 cannot receive the infrared light from the first touch element 600, thereby determining the user's click position through the first touch element 600 and the second touch element 700.

[0127] It is worth mentioning that the touch display device is set as an infrared touch display device, and the cover plate assembly 300 may include a cover plate, which may be set on the light-emitting side of the display panel 200. The cover plate may be bonded and fixed to the front side of the frame 100 through a structure such as an adhesive layer, so that the cover plate can play a certain supporting and protective role on the display panel 200.

[0128] Reference Fig.10 and Fig.11In some possible implementations, the mounting structure 111 may be provided with a mounting groove 1111, and the mounting groove 1111 accommodates at least a portion of the upper front shell 500. The upper front shell 500 may be provided with connecting screws, and the upper front shell 500 may be connected to the mounting structure 111 through the connecting screws.

[0129] When fixing the upper front shell 500 and the mounting structure 111 to each other, the upper front shell 500 can be inserted into the mounting groove 1111, so that the mounting groove 1111 can play a certain guiding role, and then the connecting screws are connected to the upper front shell 500 and the mounting structure 111, so that the upper front shell 500 can be connected to the mounting structure 111 through the connecting screws, thereby realizing the connection between the upper front shell 500 and the mounting structure 111.

[0130] For example, the upper front shell 500 may be provided with an installation opening 520, which may be connected to the upper accommodation cavity 510. The first touch element 600 may enter the upper accommodation cavity 510 through the installation opening 520, thereby enabling the first touch element 600 to be installed.

[0131] Reference Figure 10-12 The upper front shell 500 may be provided with a movable blocking member 530 , which may at least be used to block the mounting opening 520 , so as to close the upper accommodating cavity 510 through the blocking member 530 , thereby reducing the possibility of the first touch element 600 moving in the upper accommodating cavity 510 .

[0132] When the first touch element 600 and the upper front shell 500 are fixed to each other, the first touch element 600 can be installed in the upper accommodating cavity 510 through the installation opening 520 of the upper front shell 500, and then the blocking member 530 can be installed on the upper front shell 500, so that the blocking member 530 can block the installation opening 520 of the upper front shell 500, thereby closing the upper accommodating cavity 510, reducing the possibility of the first touch element 600 detaching from the upper accommodating cavity 510, and making the connection between the first touch element 600 and the upper front shell 500 more stable.

[0133] Exemplarily, the blocking member 530 may include a fitting portion 531. The fitting portion 531 may fit the surface of the upper front housing 500 that faces away from the upper frame 110.

[0134] The blocking member 530 may include a blocking portion 532. The blocking portion 532 may be connected to the fitting portion 531, and the plane where the blocking portion 532 is located may be perpendicular to the plane where the fitting portion 531 is located. The blocking portion 532 may be used to block the installation port 520, and the blocking portion 532 may be provided with an insertion port 5321, and the insertion port 5321 may accommodate at least part of the cover plate assembly 300.

[0135] When installing the sealing member 530 on the upper front shell 500, the fitting portion 531 can be fitted onto the surface of the upper front shell 500 facing away from the upper frame 110, and then the plug-in port 5321 located on the sealing portion 532 can be connected to the cover assembly 300, so that at least part of the cover assembly 300 can be inserted into the plug-in port 5321, and the sealing portion 532 can block the installation port 520, thereby reducing the possibility of the first touch element 600 detaching from the upper accommodating cavity 510.

[0136] The surface of the fitting portion 531 facing the upper frame 110 may be provided with a convex point 5311. The surface of the upper front shell 500 facing away from the upper frame 110 may be provided with a concave point 540, and the convex point 5311 may be used in conjunction with the concave point 540. The fitting portion 531 may be provided as an elastic fitting portion 531, so that the process of installing the blocking member 530 on the upper front shell 500 is more convenient.

[0137] For example, when the blocking piece 530 is installed on the upper front shell 500, the blocking portion 532 can be filled in the installation port 520, and at least part of the cover assembly 300 can be inserted in the insertion port 5321. The elastic fitting portion 531 is deformed, and then the elastic fitting portion 531 is reset, so that the elastic fitting portion 531 can drive the protrusion 5311 to move toward the recess 540 and be inserted in the recess 540, thereby realizing the installation process of the blocking piece 530.

[0138] In some possible implementations, the left frame 130 may be connected to the left front shell and one of the first touch element 600 and the second touch element 700 , and the right frame 140 may be connected to the right front shell and the other of the first touch element 600 and the second touch element 700 .

[0139] The first touch element 600 and the second touch element 700 located on the left front shell and the right front shell implement the touch control process of the infrared touch display device, making the touch control process of the infrared touch display device more accurate and improving the touch control accuracy of the infrared touch display device.

[0140] Exemplarily, the left front shell may be provided with a left accommodating cavity, which may be provided with a left opening, and the right front shell may be provided with a right accommodating cavity, which may be provided with a right opening.

[0141] The left opening can be oriented toward the right side, and the right opening can be oriented toward the left side. The left opening can be arranged opposite to the right opening, so as to realize the emission and sensing process of infrared light through the left opening and the right opening.

[0142] For example, the number of the touch components can be set to be multiple. The touch components located on the left front shell and the right front shell can include a first touch element 600 and a second touch element 700 that match each other.

[0143] One of the first touch element 600 and the second touch element 700 may be used to emit infrared light, and the other of the first touch element 600 and the second touch element 700 may be used to sense infrared light.

[0144] The first touch element 600 may be disposed in the left accommodation cavity, and the functional end of the first touch element 600 may be directed toward the second touch element 700 through the left opening.

[0145] The second touch element 700 can be disposed in the right accommodating cavity, and the functional end of the second touch element 700 can be directed toward the first touch element 600 through the right opening to achieve mutual cooperation between the first touch element 600 and the second touch element 700 to determine the user's click position.

[0146] For example, in the touch components located in the left front shell and the right front shell, the first touch element 600 can be used to emit infrared light. The first touch element 600 can extend in the vertical direction, and the first touch element 600 can emit a plurality of infrared light rays arranged in sequence in the horizontal direction. The second touch element 700 can extend in the vertical direction, and the second touch element 700 can be used to sense infrared light.

[0147] When the touch process of the infrared touch display device is implemented by the coordinated first touch element 600 and second touch element 700, the first touch element 600 can emit infrared light to the right through the left opening, and the second touch element 700 can receive infrared light from the first touch element 600 through the right opening.

[0148] When the user clicks on the cover assembly 300, the user's finger or stylus will block and intercept the infrared light from the first touch element 600, so that at least part of the second touch element 700 cannot receive the infrared light from the first touch element 600, thereby determining the user's click position through the first touch element 600 and the second touch element 700.

[0149] Through the two coordinated touch components, the touch components located at the left front shell and the right front shell can determine the vertical position of the user's click, and the touch components located at the upper front shell 500 and the lower front shell 400 can determine the horizontal position of the user's click, thereby making the determination of the user's click position more accurate.

[0150] For example, the structure and connection method of the left front shell and the left frame 130 can refer to the structure and connection method of the upper front shell 500 and the upper frame 110. The structure and connection method of the right front shell and the right frame 140 can refer to the structure and connection method of the upper front shell 500 and the upper frame 110, and the embodiments of the present application will not be repeated here.

[0151] The left front shell and the right front shell may be provided with a blocking piece 530 to make the installation of the first touch element 600 and the second touch element 700 located in the left front shell and the right front shell more stable. As for the structure of the blocking piece 530, reference may be made to the above, and the embodiments of the present application will not be repeated here.

[0152] To sum up, the touch display device of the embodiment of the present application includes a frame 100 having a mounting structure 111 and a lower front shell 400. The frame 100 can be connected to the upper front shell 500 and the first touch element 600 through the mounting structure 111, and the lower front shell 400 can be used to connect the second touch element 700, thereby enriching the functions of the frame 100 and the lower front shell 400.

[0153] When the touch display device is a capacitive touch display device, the mounting structure 111 is not connected to the upper front shell 500 and the first touch element 600 , and the lower front shell 400 is not provided with the second touch element 700 .

[0154] Furthermore, the cover assembly 300 may include a capacitive touch film layer, which is used at least to obtain a click position of a user, so that a touch control process of the touch display device can be realized through the capacitive touch film layer.

[0155] Alternatively, the touch display device is an infrared touch display device, the mounting structure 111 connects the upper front shell 500 and the first touch element 600, the lower front shell 400 is provided with a second touch element 700, the first touch element 600 and the second touch element 700 cooperate with each other to obtain the user's click position, so that the touch process of the touch display device can be realized through the first touch element 600 and the second touch element 700.

[0156] Compared with the frame 100 of the touch display device in the related art, the touch display device in the embodiment of the present application is provided with a frame 100 having a mounting structure 111, and can connect the upper front shell 500 and the first touch element 600 through the mounting structure 111, and connect the second touch element 700 through the lower front shell 400, so that the frame 100 can be suitable for capacitive touch display devices and infrared touch display devices, thereby increasing the scope of use of the frame 100 and improving the versatility and interchangeability of the frame 100.

[0157] Furthermore, since the lower front shell 400 can at least be used to accommodate the wiring of structures such as the display panel 200 and the cover assembly 300, the lower front shell 400 can also be used to install structures such as buttons, so that the touch display device can be controlled through the buttons and other structures located on the lower front shell 400, making the functions of the lower front shell 400 more abundant.

[0158] The embodiment of the present application provides a touch display device, including a frame 100 , a cover assembly 300 and a lower front shell 400 .

[0159] The frame 100 includes an upper frame 110 and a lower frame 120 that are relatively arranged, and a left frame 130 and a right frame 140 that are relatively arranged. The upper frame 110 is provided with a mounting structure 111; the cover assembly 300 is arranged on the front side of the frame 100; and the lower front shell 400 is arranged on the lower frame 120.
