Description

Bezel components and touch display

[0001] This disclosure claims priority to Chinese Patent Application No. 202411203856.9, filed on August 29, 2024, entitled "Bezel Assembly and Touch Display", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of touch technology, and in particular to a bezel assembly and a touch display. Background Technology

[0003] Touchscreen displays are one of the most widely accepted computer input methods for ordinary people, following keyboards, mice, handwriting tablets, and voice input. Infrared technology in touchscreen displays (also known as infrared touchscreens) involves installing infrared emitters and receivers around the screen's bezel, forming a crisscrossing infrared grid above the screen. When any opaque object (such as a finger or stylus) touches the screen, it blocks the horizontal and vertical infrared rays passing through that location, thus allowing the system to determine the touch point's position on the screen.

[0004] An infrared touch display mainly consists of a screen, a bezel, a touchpad, and light filters arranged around the screen. The bezel and light filters are assembled to form a cavity, in which the touchpad is located. The touchpad has an infrared emitter or receiver positioned corresponding to the light filters. The light emitted by the infrared emitter passes through the light filters on its side and hits the top of the screen, then passes through the light filters on the opposite side and enters the infrared receiver, thus forming a crisscrossing infrared light grid above the screen.

[0005] When infrared touch displays are used in environments with high humidity, such as the humid weather in southern China, or after wiping the infrared touch display with a damp cloth, the condensed or residual moisture on the display can easily seep into the touchpad chamber along gaps (such as the gap between the screen and the filter strip, or the gap between the filter strip and the frame). Over time, this can easily cause short circuits in the touchpad's circuitry or corrosion of its components, ultimately leading to the malfunction of the infrared touch display. Summary of the Invention

[0006] This disclosure provides a bezel assembly and a touch display that can solve the problem of short circuits or corrosion caused by water ingress in the prior art touchpad.

[0007] In a first aspect, this disclosure provides a frame assembly, the frame assembly including a frame, a touchpad, and a filter strip;

[0008] The frame is a tubular structure with windows distributed along its length. The touchpad has a signal device. The filter strip is a tubular structure with protrusions distributed along its length and protruding away from the space inside the tube. The filter strip has a filtering function at the corresponding protrusion positions.

[0009] The touch panel is located in the light filter strip, and the signal device and the protrusion are positioned opposite each other. The light filter strip is located in the frame, and the protrusion is located in the window. The protrusion is used to press against the screen of the touch display.

[0010] In the solution disclosed herein, the bezel assembly of the touch display has a tubular light filter strip, with the touchpad located within the tubular space of the light filter strip. The light filter strip is seamless circumferentially, preventing moisture from easily entering the bezel assembly and thus reducing the risk of short circuits and corrosion on the touchpad due to water ingress, effectively protecting it. Furthermore, the light filter strip has a protrusion at the location corresponding to the touchpad's signal transmitter. This protrusion is used to press against the screen, ensuring a seamless connection between the protrusion and the screen surface. This reduces the feeling of distance when touching the screen, resulting in a better user experience.

[0011] In one possible implementation, the filter strip is snapped into the frame.

[0012] In the solution disclosed herein, the frame and the filter strip are fixedly connected by a snap-fit ​​mechanism. Compared to a screw-fixed connection, the filter strip does not require screw holes, further improving its water-blocking effect. Moreover, the snap-fit ​​connection between the frame and the filter strip simplifies the assembly process, facilitating quick installation and removal of the frame assembly.

[0013] In one possible implementation, the outer surface of the filter strip that contacts the frame has drainage grooves distributed along the length direction, and / or the inner surface of the frame that contacts the filter strip has drainage grooves distributed along the length direction.

[0014] In the solution disclosed herein, liquid entering between the frame and the filter strip through the contact gap can be discharged via a drainage channel between the frame and the filter strip, giving the frame assembly both drainage and hydrophobic functions. Furthermore, by draining water from the frame assembly through the drainage channel, less water enters the filter strip, which also helps protect the touchpad within the filter strip.

[0015] In one possible implementation, the tubular filter strip is open at one or both ends along its length, and the frame assembly further includes a sealing plug mounted on the opening;

[0016] The sealing plug has a wire-passing hole between it and the inner surface of the filter strip, or the sealing plug has a wire-passing hole.

[0017] In the scheme disclosed herein, the sealing plug can be inserted into the opening of the filter strip to form a sealed space inside the tube of the filter strip, preventing water from entering from the opening at the end of the filter strip, thereby further improving the airtightness and waterproofness of the filter strip. The better the airtightness of the filter strip, the better the waterproofness. And the better the waterproofness, the better the protection of the touch panel inside the tube, and the less likely the touch panel is to short circuit or corrode.

[0018] In a second aspect, a touch display is provided, the touch display including a screen, a back panel and the bezel assembly described in the first aspect;

[0019] The back panel is located on the back of the screen. The frame assembly is arranged on the first and second sides of the screen that are opposite to each other. The frame of the frame assembly is fixedly connected to the back panel, and the protrusion of the frame assembly is pressed against the front of the screen.

[0020] In one possible implementation, the screen is quadrilateral in shape, and the bezel components are arranged on the first and second sides of the screen that are opposite each other, as well as on the third and fourth sides that are opposite each other. The touch display also includes a plurality of corner covers, and two adjacent bezel components are connected by the corner covers.

[0021] In the solution disclosed herein, bezel components are arranged around the screen to form a two-dimensional light detection network on the screen surface, and the screen is reinforced with protrusions for filter strips around the screen, which helps to improve the stability of the screen.

[0022] In one possible implementation, the corner cap located on the upper side of the screen has a liquid collection tank, and the opening of the liquid collection tank faces the contact gap between the corner cap and the frame of the frame assembly located on the upper side of the screen, and the tank wall has a drain outlet near the bottom of the tank.

[0023] For example, a first corner cap connected to a first frame assembly on the left side of the screen and a third frame assembly on the upper side has a first liquid collection tank. The opening of the first liquid collection tank faces the contact gap between the first corner cap and the third frame assembly, so that liquid entering through the contact gap can fall into the first liquid collection tank and be discharged through the first drain port of the first liquid collection tank.

[0024] For example, the second corner cover of the second frame assembly connected to the right side of the screen and the third frame assembly on the top side has a second liquid collection tank. The opening of the second liquid collection tank faces the contact gap between the second corner cover and the third frame assembly, so that liquid entering through the contact gap can fall into the second liquid collection tank and be discharged through the second drain port of the second liquid collection tank.

[0025] In one possible implementation, the liquid collection tank is also used to drain liquid through the slot into a drainage channel between the frame of the frame assembly and the filter strip.

[0026] In the solution disclosed herein, when a large amount of liquid accumulates in the collection tank, the liquid in the collection tank can also overflow from the opening of the collection tank and flow into the drainage channel between the frame and the filter strip, and be discharged through the drainage channel.

[0027] For example, when there is a lot of liquid in the first liquid collection tank, the liquid will not only be discharged from the first drain outlet of the first liquid collection tank, but also from the tank opening of the first liquid collection tank, and discharged into the drainage channel between the frame of the first frame assembly and the filter strip, and discharged through the drainage channel.

[0028] For example, when there is a lot of liquid in the second liquid collection tank, the liquid will not only be discharged from the second drain outlet of the second liquid collection tank, but also from the outlet of the second liquid collection tank, and discharged into the drainage channel between the frame of the second frame assembly and the filter strip, and discharged through the drainage channel.

[0029] In one possible implementation, the cross-section of the liquid collection tank is V-shaped, U-shaped, or funnel-shaped.

[0030] In one possible implementation, the corner cover located on the lower side of the screen has a drain port.

[0031] For example, the triangular cover connecting the first frame assembly on the left side of the screen and the fourth frame assembly on the lower side has a third drain port. Liquid that enters between the frame of the first frame assembly and the filter strip flows downward and is eventually discharged through the third drain port.

[0032] For example, the fourth corner cover of the second frame assembly on the right side of the screen and the fourth frame assembly on the lower side has a fourth drain port. Liquid that enters between the frame of the second frame assembly and the filter strip flows downward and is eventually discharged through the fourth drain port. Attached Figure Description

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0043] This embodiment provides a touch display, specifically an optical technology touch display, such as an infrared light technology touch display. This touch display can be a screen mounted on a wall or supported on a table in public places, such as in hospitals, train stations, airports, government and enterprise facilities, and schools, or it can be used in offices and homes. This embodiment does not limit the specific application scenarios of the touch display.

[0044] The touchpad of this touch display is housed within the chamber of a tubular light filter strip. This strip is seamless circumferentially, effectively preventing moisture from entering the touchpad chamber. Furthermore, both ends of the filter strip are sealed with plugs for additional moisture protection. Additionally, drainage channels exist between the filter strip and the frame, allowing moisture that enters the frame and filter strip to drain away. Drainage channels are also provided on the corner caps connecting the frame, allowing moisture that enters the area between the frame and filter strip to drain away. Therefore, the touch display possesses both water-blocking and water-repellent properties. Moreover, the filter strip and frame are fixedly connected via a snap-fit ​​mechanism, enabling screwless installation. The filter strip requires no drilling, ensuring a seamless circumferential surface. This snap-fit ​​assembly method also facilitates quick installation and removal of the frame components. Furthermore, the filter strip is pressed against the screen, resulting in a lower touch height and reduced tactile feedback, improving the user's touch experience.

[0045] The features of touch displays are described in detail below.

[0046] Figure 1 shows a structural schematic diagram of the touch display, Figure 2 shows a split schematic diagram of the touch display, and Figure 3 shows a cross-sectional schematic diagram of the touch display. Referring to Figure 2, the touch display includes a screen 100 and bezel components, wherein the number of bezel components is at least one pair. In each pair of bezel components, one bezel component contains a signal transmitter responsible for emitting light signals, and the other bezel component contains a signal receiver responsible for receiving light signals.

[0047] For example, bezel components are arranged on both the first and second sides of the screen 100, which are positioned opposite each other. Each bezel component contains a signal transmitter; for instance, the signal transmitter on the first side of the bezel component acts as a signal transmitter, and the signal transmitter on the second side acts as a signal receiver, thus forming a one-dimensional light detection network on the surface of the screen 100. The first and second sides can be the left and right sides of the screen 100, or the top and bottom sides of the screen 100.

[0048] For example, referring to Figure 1, a rectangular screen 100 has frame components arranged on its first and second opposite sides, as well as on its third and fourth opposite sides. The signal transmitters on the first and third side frame components are signal transmitters, while the signal receivers on the second and fourth side frame components are signal receivers, thus forming a two-dimensional light detection network on the surface of the screen 100. The first and second sides can be the left and right sides of the screen 100, while the third and fourth sides are the top and bottom sides. For example, the first side could be the left side of the screen 100, the second side the right side, the third side the top side, and the fourth side the bottom side.

[0049] For ease of explanation, Figure 1 is used as an example to illustrate that the touch display includes four border components distributed on the left, right, top, and bottom of the screen 100, with the first side being the left side of the screen 100 and the third side being the top side of the screen 100.

[0050] For ease of explanation, referring to Figure 2, the border component located on the left side of the screen 100 is designated as the first border component 301, the border component located on the right side of the screen 100 is designated as the second border component 302, the border component located on the top side of the screen 100 is designated as the third border component 303, and the border component located on the bottom side of the screen 100 is designated as the fourth border component 304.

[0051] Referring again to Figures 1 and 2, the touch display also includes multiple corner covers arranged in the four bezel components around the screen 100, with adjacent bezel components connected by corner covers. For example, the first bezel component 301 on the left side of the screen 100 and the third bezel component 303 on the upper side are connected by a first corner cover 401; the second bezel component 302 on the right side of the screen 100 and the third bezel component 303 on the upper side are connected by a second corner cover 402; the first bezel component 301 on the left side of the screen 100 and the fourth bezel component 304 on the lower side are connected by a third corner cover 403; and the second bezel component 302 on the right side of the screen 100 and the fourth bezel component 304 on the lower side are connected by a fourth corner cover 404.

[0052] Referring to Figure 3, the touch display also includes a back panel 200, which is located on the back of the screen 100. The back panel 200 is fixedly connected to the frame 1 of the four frame components, such as by snap-fit ​​and / or screws.

[0053] The above is an introduction to the frame features of a touch display. The following section introduces the features of the bezel components of a touch display. Unless otherwise specified, the bezel components described below refer to any one of the four bezel components mentioned above.

[0054] Figure 4 shows a schematic diagram of the frame assembly. Referring to Figure 4, the frame assembly includes a frame 1, a touchpad 2, and a light filter strip 3. The frame 1, touchpad 2, and light filter strip 3 are all elongated strips. Referring to Figure 3, the frame 1 has a tubular structure, the light filter strip 3 is located within the frame 1, and the light filter strip 3 also has a tubular structure. The touchpad 2 is located within the light filter strip 3.

[0055] The bezel 1 serves as the housing of the bezel assembly and also as the mid-frame of the touchscreen display 100. If the screen 100 is relatively large, such as an information display screen or advertising screen, then the bezel 1 needs to have sufficient strength to resist deformation in order to support the screen 100. The bezel 1 can be made of a material with high structural strength, for example, aluminum profile. If the screen 100 is not very large, such as a television screen, then the bezel 1 can be made of aluminum profile or iron.

[0056] Since the material used for the frame 1 is generally opaque or has poor light transmittance, in order for the touchpad 2 to emit or receive light signals, as shown in Figure 4, the frame 1 has windows 11 distributed along the length direction.

[0057] Among them, the filter strip 3 has the property of filtering light, allowing light of a specific wavelength to pass through, such as allowing infrared light to pass through. The material of the filter strip 3 can be purplish-red polycarbonate (PC), which is an extruded part.

[0058] Referring to Figure 3, the inner wall of the tubular filter strip 3 has a slot, in which the touch panel 2 is snapped. The touch panel 2 has a signal transmitter, which is either a light signal transmitter or a light signal receiver. Continuing to refer to Figure 3, the inner wall of the tubular filter strip 3 forms a first light surface 31 at the position corresponding to the signal transmitter 21 of the touch panel 2, and the outer wall of the chamber 30 forms a second light surface 32 at the position corresponding to the signal transmitter 21 of the touch panel 2. The thickness between the first light surface 31 and the second light surface 32 is greater than the thickness of the filter strip 3 at other positions, thereby forming a protrusion 33 that protrudes into the tubular space opposite to the tubular filter strip 3. The protrusion 33 is elongated and distributed along the length of the filter strip 3.

[0059] In one example, the filter strip 3 may be light-filtering at all positions, allowing the light signal emitted by the signaler 21 to pass through, or the filter strip 3 may be light-filtering at the position of the protrusion 33, allowing the light signal emitted by the signaler 21 to pass through at the position of the protrusion 33.

[0060] Referring to Figure 3, the filter strip 3 is installed in the frame 1, and the boss 33 is located in the window 11 of the frame 1. Thus, the light signal emitted by the signal transmitter 21 of the touch panel 2 is incident on the first light surface, passes through the boss 33, and is emitted through the second light surface.

[0061] Referring to Figure 3, the touchpad 2 is located within the space of the circumferentially seamless tubular light filter strip 3. Moisture entering the frame assembly is less likely to seep into the light filter strip 3, effectively protecting the touchpad 2 and preventing short circuits and corrosion due to water ingress. Furthermore, the light filter strip 3 has a protrusion 33 at the position corresponding to the signal transmitter 21. This protrusion 33 presses against the screen 100, ensuring that a light detection mesh is evenly distributed within the distance H between the center line of the screen 100 and the signal transmitter 21. This avoids a feeling of separation when touching the screen 100. Therefore, by pressing the protrusion 33 against the screen 100, the user's feeling of separation when touching the screen is reduced, thus improving the user experience. Also, because the protrusion 33 presses against the screen 100, external dust and moisture are less likely to enter between the screen 100 and the back panel 200, which also helps protect the internal circuitry of the screen 100. Moreover, the protrusion 33 of the filter strip 3 is pressed onto the screen 100, which can also serve to fix the screen 100.

[0062] As described above, the protrusion 33 of the filter strip 3 is located in the window 11 of the frame 1. For example, referring to FIG3, the protrusion 33 may extend slightly beyond the window 11. Alternatively, the protrusion 33 may be flush with the window 11. Of course, the protrusion 33 may also be lower than the window 11 and not extend beyond it. In this embodiment, there is no specific limitation on whether the protrusion 33 extends beyond the window 11, as long as the window 11 can avoid the light signal and allow the light signal to pass through.

[0063] In one example, regarding the size of the window 11 on the border 1, as described above, the window 11 is distributed along the length direction of the border 1. Therefore, the length of the window 11 can be the same as the length of the border 1, or the length of the window 11 can be less than the length of the border 1. However, the length of the window 11 must be greater than or equal to the length of the signaler 21 so that the light signals emitted by the signaler 21 can all be emitted through the window 11.

[0064] The width of window 11 is at least greater than the width of boss 33. Referring to Figure 3, this width refers to the vertical dimension, allowing boss 33 to extend into window 11. As shown in Figure 3, the width of window 11 is much greater than the width of boss 33, so the filter strip 3 can also be inserted into frame 1 through window 11. Alternatively, the filter strip 3 can be pushed into frame 1 through the openings at both ends of frame 1.

[0065] In this embodiment, there is no specific limitation on whether the filter strip 3 is installed into the frame 1 through the window 11 or through the opening at the end of the frame 1.

[0066] Regarding the fixing method between the filter strip 3 and the frame 1, in one example, the filter strip 3 is installed in the frame 1 by a snap-fit ​​method. For example, referring to Figure 3, the outer surface of the filter strip 3 has a groove, and the inner surface of the frame 1 has a protrusion. The filter strip 3 is located in the tubular frame 1, and the protrusion of the frame 1 snaps into the groove of the filter strip 3, thereby achieving the snap-fit ​​connection between the filter strip 3 and the frame 1. This snap-fit ​​method achieves screwless fixing, eliminating the need for screw holes in the filter strip 3 and helping to ensure a seamless circumferential connection. Moreover, the snap-fit ​​assembly method is simple to assemble, has fewer parts, and can meet the requirements of quick installation and disassembly. Of course, the filter strip 3 and the frame 1 can also be fixed together by screws.

[0067] In one example, the tubular filter strip 3 is open at one or both ends along its length, allowing the touchpad 2 to be inserted into the filter strip 3 through the openings. However, because the ends of the filter strip 3 are open, moisture and dust can easily enter the interior of the filter strip 3. To avoid this, as shown in Figure 5, the frame assembly also includes a sealing plug 4, which is mounted on the openings. For example, the sealing plug 4 can be inserted into the opening of the filter strip 3, or it can cover and fasten onto the opening of the filter strip 3.

[0068] In one example, the four bezel components located around the screen 100 may all include the sealing plug 4. Alternatively, in another example, the third bezel component 303 located on the upper side of the screen 100 may include the sealing plug 4, and the bezel components located on both sides (left and right sides) of the screen 100 may also include the sealing plug 4, while the fourth bezel component 304 located on the lower side of the screen 100 may not include the sealing plug 4. This is because the fourth bezel component 304 located on the lower side of the screen 100 is horizontally placed, making it difficult for water to enter the tube space of the filter strip 3 from the opening at the left or right end.

[0069] In one example, because there is an electrical connection between the touchpads 2 in two adjacent frame components, for example, the touchpads 2 of the two frame components are electrically connected through a flexible circuit board, the filter strip 3 cannot be in a completely sealed state. Therefore, a wire hole can be provided on the sealing plug 4, or the sealing plug 4 can be inserted into the opening of the filter strip 3, and there is a gap between the sealing plug 4 and the inner surface of the filter strip 3, which can serve as a wire hole.

[0070] In one example, the bezel component also has a drainage function. Accordingly, there can be a drainage channel between the bezel 1 and the filter strip 3. Water that enters through the connection gap between the bezel 1 and the filter strip 3 can be drained through the drainage channel to the bottom of the touch display and discharged through the drain or gap at the bottom.

[0071] For example, as shown in Figure 6, which is a cross-sectional schematic diagram of the frame 1, the inner surface of the frame 1 that contacts the filter strip 3 has a drainage groove 12, wherein the drainage groove 12 is elongated and distributed along the length direction of the frame 1.

[0072] For example, the outer surface of the filter strip 3 that contacts the frame 1 has drainage grooves, wherein the drainage grooves are elongated and distributed along the length of the frame 1.

[0073] For example, both the inner surface of the frame 1 and the outer surface of the filter strip 3 have drainage grooves, wherein the drainage grooves on the frame 1 are distributed along the length direction of the frame 1, and the drainage grooves on the filter strip 3 are distributed along the length direction of the filter strip 3.

[0074] In one example, it could be four bezel components located around the screen 100, with drainage channels between the bezel 1 and the light filter strip 3. Alternatively, in another example, it could be bezel components located on the left and right sides of the screen 100, with drainage channels between the bezel 1 and the light filter strip 3.

[0075] In one example, to allow water flowing into the drainage channel to drain, one method is to have a drain outlet on the corner cover located on the lower side of the screen 100. For example, as shown in Figure 7, the triangular cover 403 connecting the first frame assembly 301 on the left side of the screen 100 and the fourth frame assembly 304 on the lower side has a third drain outlet 4031, and the fourth corner cover 404 connecting the second frame assembly 302 on the right side of the screen 100 and the fourth frame assembly 304 on the lower side has a fourth drain outlet 4041. Thus, water in the drainage channel within the first frame assembly 301 on the left side of the screen 100 is drained through the third drain outlet 4031 of the third corner cover 403, and water in the drainage channel within the second frame assembly 302 on the right side of the screen 100 is drained through the fourth drain outlet 4041 of the fourth corner cover 404. The drainage channel is the one described above located between the frame 1 and the filter strip 3.

[0076] Another way to drain water flowing into the drain tank is to not provide drain ports on the third corner cover 403 and the fourth corner cover 404, but to have a contact gap between the third corner cover 403 and the frame 1 of the lower fourth frame assembly 304 (see Figure 7), and also to have a contact gap between the fourth corner cover 404 and the frame 1 of the lower fourth frame assembly 304 (see Figure 7). In this way, the water in the drain tank can be drained through the contact gap.

[0077] In one example, the bezel assembly can drain water not only through the drainage channel between the bezel 1 and the light filter strip 3, but also through a collection tank on the corner cover. Correspondingly, the corner cover located on the upper side of the screen 100 has a collection tank with its opening facing upwards and towards the contact gap between the corner cover and the bezel 1 of the upper bezel assembly. Furthermore, the tank wall has a drain outlet near the bottom, located on the back wall of the tank, which is the side closest to the touch display back panel. In this way, water entering from the contact gap between the corner cover and the bezel 1 can fall into the collection tank and be drained outwards through the drain outlet.

[0078] For example, as shown in Figure 8, the first corner cover 401 connecting the first frame assembly 301 on the left side of the screen 100 and the third frame assembly 303 on the upper side has a first liquid collection tank 4011, and the second corner cover 402 connecting the second frame assembly 302 on the right side of the screen 100 and the third frame assembly 303 on the upper side has a second liquid collection tank 4021. Referring to Figure 8, the opening of the first liquid collection tank 4011 faces the contact gap between the first corner cover 401 and the frame 1 of the third frame assembly 303. Liquid entering through this contact gap falls into the first liquid collection tank 4011 and is discharged through the first drain port 4012 of the first liquid collection tank 4011. Continuing to refer to Figure 8, the opening of the second liquid collection tank 4021 faces the contact gap between the second corner cover 402 and the frame 1 of the third frame assembly 303. Liquid entering through this contact gap falls into the second liquid collection tank 4021 and is discharged through the second drain port 4022 of the second liquid collection tank 4021.

[0079] In one example, the shape of the liquid collection tank can be V-shaped, U-shaped, or funnel-shaped. For example, continuing to refer to Figure 8, the cross-sectional shape of the first liquid collection tank 4011 is V-shaped, and the cross-sectional shape of the second liquid collection tank 4021 is V-shaped.

[0080] It should be noted that the cross-sectional shape of the first liquid collection tank 4011 and the cross-sectional shape of the second liquid collection tank 4021 can be the same or different, as shown in Figure 8.

[0081] In one example, when there is a lot of liquid in the collection tank, the liquid can be discharged not only from the drain outlet but also from the opening of the collection tank. The liquid discharged from the opening of the collection tank flows between the frame 1 and the filter strip 3, and is discharged outward along the drainage channel between the frame 1 and the filter strip 3.

[0082] For example, when there is a lot of liquid in the first liquid collection tank 4011, the liquid will not only be discharged from the first drain port 4012 of the first liquid collection tank 4011, but also be discharged from the opening of the first liquid collection tank 4011 and discharged into the drainage channel 12 between the frame 1 and the filter strip 3 of the first frame assembly 301, and discharged through the drainage channel 12.

[0083] For example, when there is a lot of liquid in the second liquid collection tank 4021, the liquid will not only be discharged from the second drain port 4022 of the second liquid collection tank 4021, but also be discharged from the groove opening of the second liquid collection tank 4021, and discharged into the drainage groove 12 between the frame 1 and the filter strip 3 of the second frame assembly 302, and discharged through the drainage groove 12.

[0084] Based on the above, the filter strip of the bezel assembly of the touch display has a tubular structure, and the touch panel 2 is located in the tubular space of the circumferentially seamless filter strip 3. Therefore, water entering the bezel assembly is less likely to enter the filter strip 3, thereby effectively protecting the touch panel 2 and preventing short circuits and corrosion caused by water ingress.

[0085] Furthermore, a sealing plug 4 is installed at the opening at the end of the filter strip 3. The sealing plug 4 further prevents liquid from entering through the opening at the end of the filter strip 3, further protecting the touch panel 2 and making the touch panel 2 less prone to short circuits and corrosion due to water ingress.

[0086] A drainage groove is also provided between the frame 1 and the filter strip 3. Liquid that enters between the frame 1 and the filter strip 3 through the contact gap between the frame 1 and the filter strip 3 can be discharged outward through the drainage groove, thus the frame assembly has drainage and hydrophobic functions.

[0087] The corner cover located on the upper part of the screen is also provided with a liquid collection tank. The opening of the liquid collection tank faces the contact gap between the corner cover and the upper third frame assembly. Liquid entering through the contact gap between the corner cover and the third frame assembly can fall into the liquid collection tank and be discharged through the drain port of the liquid collection tank.

[0088] In addition, the filter strip 3 has a protrusion 33 at the position of the signal device 21 corresponding to the touchpad 2. The protrusion 33 is pressed against the surface of the screen 100, so that there is no gap between the protrusion 33 and the surface of the screen 100. Therefore, when touching the screen 100, the sense of isolation can be reduced. The weaker the sense of isolation, the better the user experience.

[0089] Furthermore, the frame 1 and the filter strip 3 are fixedly connected by a snap-fit ​​mechanism. Compared to a screw-fixed connection, the filter strip 3 does not require screw holes, further improving its water-blocking effect. Moreover, the snap-fit ​​connection between the frame and the filter strip simplifies assembly, facilitating quick installation and removal of the frame assembly.

[0090] In this embodiment, the bezel assembly of the touch display has a tubular light filter strip. The touchpad 2 is located within the tubular space of the light filter strip 3. Since the light filter strip 3 is seamless in its circumference, moisture entering the bezel assembly is less likely to penetrate into the light filter strip 3, thus preventing short circuits and corrosion of the touchpad 2 due to water ingress and effectively protecting it. Furthermore, the light filter strip 3 has a protrusion at the position corresponding to the touchpad's signal transmitter. This protrusion is used to press against the screen 100, ensuring a seamless connection between the protrusion 33 and the surface of the screen 100. This reduces the feeling of distance when touching the screen 100, resulting in a better user experience.
