Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to an optical touch bezel and display device. Background Technology

[0002] In the field of display technology, infrared touch technology dominates most of the market due to its mature technology, accurate touch detection, and relatively low cost.

[0003] An infrared touch display device typically includes a display screen, a support frame, a light filter strip, and a driver board. The support frame surrounds the four sides of the display screen to support it. The driver board is located within the support frame on the display side of the screen. The driver board includes multiple infrared emitters and multiple infrared receivers. The infrared emitters and receivers form a crisscrossing infrared matrix. When a user touches the screen, their finger blocks the horizontal and vertical infrared rays passing through that location, thus allowing the user to determine the touch point's position on the display screen. The light filter strip is connected to the support frame; the infrared light emitted by the infrared emitters must pass through the light filter strip before being emitted to the infrared receivers.

[0004] However, the current support frame is usually made up of four frames spliced ​​together, resulting in seams on the surface of the support frame. As a result, when wiping the infrared touch display device, water droplets can enter the support frame through the seams and corrode the driver board, leading to low reliability of the infrared touch display device.

[0082] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0083] This application provides an optical touch bezel for installation in a display device, enabling the display device to have touch functionality.

[0084] Please refer to this. Figure 1 and Figure 2 , Figure 1 This is a front view of the display surface of a display device provided in an embodiment of this application. Figure 2 This is a schematic diagram of a display device provided in an embodiment of this application. The display device may have a display panel 100, which may have a display area A1 and a non-display area A2 distributed around the display area A1. The display area A1 of the display panel 100 can be used to display an image, and the optical touch bezel in the display device can be connected to the non-display area A2 of the display panel 100.

[0085] It should be noted that the display device may include: a first optical touch frame 701, a second optical touch frame 702, and two third optical touch frames 703. The first optical touch frame 701, the second optical touch frame 702, and the two third optical touch frames 703 may be distributed around the display panel 100 to connect to the non-display area A2 in the display panel 100, respectively. Here, the extension direction of the first optical touch frame 701 and the third optical touch frame 702 may be parallel to the first direction X, and they may be arranged opposite each other in the second direction Y. The extension direction of the two third optical touch frames 703 may be parallel to the second direction Y, and they may be distributed on both sides of the first optical touch frame 701 in the first direction X, respectively. Here, both the first direction X and the second direction Y are parallel to the display surface of the display panel 100, and the first direction X may intersect the second direction Y. For example, the first direction X may intersect the second direction Y perpendicularly.

[0086] During the use of the display device, the first optical touch frame 701 in the display device is connected to the side of the display panel 100 that is close to the ground, that is, the first optical touch frame 701 is connected to the ground side of the display panel 100. Furthermore, the second optical touch frame 702 can be connected to the top side of the display panel 100, and the two third optical touch frames 703 can be connected to the left and right sides of the display panel 100 respectively.

[0087] It should also be noted that the non-display area A2 of the display panel 100 may include a bonding area F. The bonding area F of the display panel 100 has bonding traces used to connect the display element located in the display area A1 to an external component. For example, the external component may be a driver chip, which can drive the display element to operate through the bonding traces, thereby driving the display area A1 to display an image. Here, the external component can be located in the bonding area F on the side opposite to the display surface of the display panel 100. During the use of the display device, the bonding area F of the display panel 100 is generally located on the side of the display area A1 closer to the ground. Therefore, the first optical touch frame 701 can be connected to the bonding area F. That is, the optical touch frame connected to the bonding area F in the display device is the first optical touch frame 701, and thus the second optical touch frame 702 and two third optical touch frames 703 can be identified.

[0088] Furthermore, the first optical touch bezel 701, the second optical touch bezel 702, and the two third optical touch bezels 703 in the display device can each include: a bezel body and an optical touch component, wherein the optical touch component can be installed inside the bezel body. Here, for example... Figure 2 and Figure 3 As shown, Figure 3 This is a schematic diagram of another display device provided in an embodiment of this application. Figure 3 The schematic diagram of the display device shown is a rear view of a display device including only one of the two third optical touch bezels. The bezel body in the first optical touch bezel 701 can be a bezel body 200, and the optical touch component in the first optical touch bezel 701 can be an optical touch component 302. The bezel bodies in the first optical touch bezel 701, the second optical touch bezel 702, and the two third optical touch bezels 703 can be used to support the display panel 100 to realize the assembly of the display device. The optical touch components in the first optical touch bezel 701, the second optical touch bezel 702, and the two third optical touch bezels 703 can be used to realize the touch function of the display device.

[0089] For example, the optical touch components in the first optical touch frame 701, the second optical touch frame 702, and the two third optical touch frames 703 can all include infrared emitting elements and infrared receiving elements. Under the combined action of the infrared emitting and receiving elements, the infrared rays emitted by the infrared emitting elements in the first optical touch frame 701, the second optical touch frame 702, and the two third optical touch frames 703 can form an infrared detection network on the display surface of the display panel 100. When a user touches the display surface of the display panel 100, the object performing the touch operation (such as a finger) can change the infrared radiation at the touch point. The display device can then sense the touch location through the optical touch components to respond to the corresponding operation, thus realizing the touch function of the display device.

[0090] It should be noted that, as Figure 2 and Figure 3 As shown, the frame bodies of the first optical touch frame 701, the second optical touch frame 702, and the two third optical touch frames 703 are connected together by splicing. Thus, a first seam P1 exists at the splicing point between the frame body 200 of the first optical touch frame 701 and the frame body of the third optical touch frame 703. Furthermore, the first seam P1 between the frame body 200 of the first optical touch frame 701 and the frame body of the third optical touch frame 703 is located on the front of the display device. Here, the front of the display device is the side of the display panel 100 that the user can observe.

[0091] Thus, when there are water droplets on the front of the display device, the water droplets may enter the interior of the display device through the first seam P1. Since the first optical touch frame 701 is located on the ground side of the display panel 100, the water droplets may enter the interior of the frame body 200 in the first optical touch frame 701 under the action of gravity, which may erode the optical touch component 302 in the first optical touch frame 701, resulting in lower reliability of the optical touch component 302 in the first optical touch frame 701, and consequently, lower reliability of the display device.

[0092] Therefore, in order to prevent the optical touch component 302 in the first optical touch frame 701 from being corroded by moisture, this application provides an optical touch frame, and the optical touch frame in the following embodiments is the first optical touch frame in the display device.

[0093] Please refer to Figure 3 and Figure 4 , Figure 4This is a partially enlarged view of an optical touch bezel provided in an embodiment of this application. The extension direction of the bezel body 200 in the optical touch bezel can be parallel to the first direction X. The bezel body 200 in the optical touch bezel can include a plate portion 201 and a surrounding portion 202 disposed opposite to each other in a third direction Z. A receiving space D can be provided between the plate portion 201 and the surrounding portion 202 in the bezel body 200. Here, the first direction X can intersect with the third direction Z. It should be noted that the third direction Z can be perpendicular to the display surface of the display panel 100 in the display device. Therefore, the second direction Y can also intersect with the third direction Z. The optical touch component 302 in the optical touch bezel can be installed within the receiving space D of the bezel body 200.

[0094] In this application, as Figure 4 and Figure 5 As shown, Figure 5 This is a partial enlarged view of another optical touch frame provided in the embodiments of this application. The side of the plate portion 201 in the frame body 200 facing the enclosure portion 202, and / or, the side of the enclosure portion 202 away from the plate portion 201 may have a water guiding structure 203.

[0095] Here, the water-guiding structure 203 on the plate portion 201 can be located within the receiving space D of the bezel body 200. This allows water droplets entering the bezel body 200 to flow under the action of the water-guiding structure 203, preventing them from flowing onto the optical touch component 302. The water-guiding structure 203 on the enclosure portion 202 can be located outside the receiving space D of the bezel body 200. This allows water droplets on the side of the enclosure portion 202 facing away from the plate portion 201 to flow under the action of the water-guiding structure 203, preventing them from flowing into the bezel body 200 and thus preventing them from flowing onto the optical touch component 302. This reduces the possibility of moisture erosion of the optical touch component 302 and improves the reliability of the display device equipped with this optical touch bezel.

[0096] In summary, this application provides an optical touch bezel, including a bezel body and an optical touch component. The side of the bezel body facing the enclosure portion, and / or the side of the enclosure portion facing away from the bezel body, may have a water-guiding structure. Here, the water-guiding structure on the bezel body can be located within the receiving space of the bezel body, allowing water droplets entering the bezel body to flow under the action of the water-guiding structure, thus preventing water droplets from flowing onto the optical touch component. The water-guiding structure on the enclosure portion can be located outside the receiving space of the bezel body, allowing some water droplets on the side of the enclosure portion facing away from the bezel body to flow under the action of the water-guiding structure, preventing water droplets from flowing into the bezel body and thus preventing water droplets from flowing onto the optical touch component. This reduces the possibility of the optical touch component being corroded by moisture and improves the reliability of the display device equipped with this optical touch bezel.

[0097] Optionally, the extension direction of the orthographic projection of the water-guiding structure 203 in the bezel body 200 onto the plate portion 201 can intersect with the extension direction of the orthographic projection of the optical touch component 302 onto the plate portion 201. Since the extension direction of the water-guiding structure 203 can be parallel to the direction of gravity, water droplets can flow along the water-guiding structure 203 under the action of gravity, thus reducing the possibility of water droplets flowing onto the optical touch component 302, thereby reducing the possibility of the optical touch component 302 being corroded by water, and improving the reliability of the display device with the optical touch bezel installed.

[0098] For example, such as Figure 4 and Figure 5 As shown, the extension direction of the orthographic projection of the water-guiding structure 203 in the frame body 200 onto the plate portion 201 can be parallel to the second direction Y, and the extension direction of the optical touch component 302 on the plate portion 201 can be parallel to the first direction X. That is, the extension direction of the water-guiding structure 203 can intersect with the extension direction of the optical touch component 302.

[0099] If the plate portion 201 in the frame body 200 has a water-guiding structure 203, please refer to Figure 6 , Figure 6 This is a partial enlarged view of another optical touch frame provided in the embodiments of this application. The water guiding structure 203 may include: a first water guiding groove K1. The orthographic projection of the optical touch component 302 on the plate body 201 does not coincide with the area where the first water guiding groove K1 is located, so that the water droplets flowing in the first water guiding groove K1 will not cause erosion to the optical touch component 302.

[0100] Here, the first water guide channel K1 can have a certain width in the first direction X and a certain depth in the third direction Z, so that the inner wall of the first water guide channel K1 can restrict water droplets to flow only within the first water guide channel K1 and not onto the optical touch component 302. For example, the depth of the first water guide channel K1 can be greater than or equal to 0.2 mm.

[0101] Optionally, the extension direction of the orthographic projection of the optical touch component 302 on the plate portion 201 can be perpendicular to the extension direction of the first water guide channel K1. Here, the extension direction of the orthographic projection of the optical touch component 302 on the plate portion 201 is perpendicular to the extension direction of the first water guide channel K1, that is, the first direction X can be perpendicular to the second direction Y.

[0102] Optional, such as Figure 2 , Figure 3 and Figure 6 As shown, the optical touch bezel may also include a filter strip 301, and the light emitted from the optical touch component 302 in the optical touch bezel can form an infrared detection network on the display surface of the display panel 100 after passing through the filter strip 301.

[0103] The frame body 200 may further include a first connector 2011, which can be connected to the plate portion 201 and the enclosure portion 202 respectively in the third direction Z, and the first connector 2011 is used to fix the filter strip 301. In this way, the filter strip 301 can be fixed on the frame body 200 through the first connector 2011.

[0104] Optional, such as Figure 6 As shown, the first connector 2011 may include: a first connecting portion 2011a fixed to the side of the plate portion 201 facing the enclosure portion 202, and a second connecting portion 2011b fixed to the side of the enclosure portion 202 facing the plate portion 201. A first mounting groove S1 is provided between the first connecting portion 2011a and the second connecting portion 2011b. The filter strip 301 can be fixed in the first mounting groove S1, so that the filter strip 301 can be fixed on the first connector 2011.

[0105] It should be noted that, as Figure 2 As shown, in the display device, the ends of the filter strips in the two third optical touch bezels 703 facing the first optical touch bezel 701 also have a second seam P2 between them. Thus, when there are water droplets on the surface of the display device, the water droplets may enter the interior of the bezel body 200 in the first optical touch bezel 701 through the seam between the filter strips, which may cause the optical touch component 302 in the first optical touch bezel 701 to be corroded by moisture.

[0106] Here, during the use of the display device, water droplets on the display surface of the display panel 100 will accumulate on the filter strip 301 in the first optical touch frame 701 under the action of gravity. Since the display device is not installed horizontally, some of the water droplets accumulated on the filter strip 301 in the first optical touch 701 will flow along the filter strip 301 to pass through the second seam P2 to the end of the filter strip 301.

[0107] In existing technologies, such as Figure 7 As shown, Figure 7 This is a schematic diagram of water droplets flowing onto an optical touch component. The length of the filter strip 301 is shorter than the length of the optical touch component 302. Therefore, in the first direction X, the end face of the optical touch component 302 protrudes beyond the end face of the filter strip 301. Consequently, water droplets flowing to the end of the filter strip 301 can drip directly onto the optical touch component 302 along the first water flow path B1 under the influence of gravity, causing the optical touch component 302 to be eroded by water.

[0108] In this application, as Figure 3 and Figure 6 As shown, in the first direction X, both the end face of the first connector 2011 and the end face of the filter strip 301 can protrude beyond the end face of the optical touch component 302. In this way, water droplets flowing to the end of the filter strip 301 will drip off under gravity and will not fall onto the optical touch component 302, thus reducing the possibility of moisture erosion of the optical touch component 302 and improving the reliability of the display device.

[0109] Optionally, in the first direction X, the end face of the filter strip 301 may protrude beyond the end face of the first connector 2011. Alternatively, in the first direction X, the end face of the filter strip 301 may be flush with the end face of the first connector 2011. For example, the length by which the end face of the filter strip 301 protrudes beyond the end face of the first connector 2011 in the first direction X may be between 0 mm and 0.3 mm.

[0110] Here, when the end face of the filter strip 301 is flush with the end face of the first connector 2011 in the first direction X, water droplets flowing to the end face of the filter strip 301 will spread to the end face of the first connector 2011 and then drip off under the influence of gravity. Furthermore, since the end face of the first connector 201 protrudes beyond the end face of the optical touch component 302 in the first direction X, water droplets dripping from the end face of the first connector 2011 will not drip onto the optical touch component 302.

[0111] When the end face of the light filter strip 301 protrudes beyond the end face of the first connector 2011 in the first direction X, water droplets flowing onto the end face of the light filter strip 301 will drip directly. Similarly, since the end face of the light filter strip 301 protrudes beyond the end face of the optical touch component 302 in the first direction X, water droplets dripping from the end face of the light filter strip 301 will not drip onto the optical touch component 302. Here, since the first connector 2011 is internally connected to the frame body 200, water droplets flowing onto the end face of the first connector 2011 may also flow along the inner surface of the frame body 200 to the optical touch component 302. Therefore, when the end face of the light filter strip 301 protrudes beyond the end face of the first connector 2011 in the first direction X, water droplets flowing onto the end face of the light filter strip 301 will drip directly, that is, they will not flow onto the first connector 2011. This further reduces the possibility of the first infrared touch circuit board being corroded by moisture and further improves the reliability of the display device.

[0112] For example, such as Figure 8 As shown, Figure 8 This is a partial enlarged view of a bottom view of an optical touch frame provided in an embodiment of this application. In the first direction X, the length L1 by which the end face of the first connector 2011 protrudes beyond the end face of the first infrared touch panel 302 can be greater than or equal to 0.5 mm. This ensures that water droplets dripping from the end face of the first connector 2011 will not drip onto the optical touch assembly 302.

[0113] Optional, such as Figure 6 As shown, the end face of the first connector 2011 in the frame body 200 can be flush with the groove surface of the first water guide channel K1 of the water guide structure 203 facing the first connector 2011 in the first direction X. In this way, when the end face of the filter strip 301 is flush with the end face of the first connector 2011 in the first direction X, the end face of the filter strip 301, the end face of the first connector 2011, and the groove surface of the first water guide channel K1 facing the first connector 2011 in the first direction X can be flush. Thus, water droplets flowing to the end face of the filter strip 301 can also flow along the groove surface of the first water guide channel K1 facing the first connector 2011 in the first direction X into the first water guide channel K1, thereby further reducing the possibility of the optical touch component 302 being corroded by water.

[0114] When the end face of the filter strip 301 protrudes beyond the end face of the first connector 2011 in the first direction X, since the end face of the first connector 2011 is flush with the groove surface of the first water guide groove K1 facing the first connector 2011 in the first direction X, the end face of the filter strip 301 can extend into the first water guide groove K1 in the first direction X. Thus, water droplets flowing to the end face of the filter strip 301 can also drip directly into the first water guide groove K1, which can further reduce the possibility of the optical touch component 302 being corroded by moisture.

[0115] In this application, as Figure 6 As shown, the first water channel K1 can penetrate the frame body 200 in the second direction Y. That is, the side of the frame body 200 near the ground can have an opening that communicates with the first water channel K1. In this way, water droplets flowing into the first water channel K1 can flow directly to the outside of the frame body 200 under the action of gravity, avoiding the situation where water droplets flow onto the optical touch component 302.

[0116] In this application, as Figure 6 and Figure 9 As shown, Figure 9 This is a partial enlarged view of an optical touch frame without an optical touch component provided in an embodiment of this application. The frame body 201 may also include a second connector 2012 fixed inside the accommodating space D. The second connector 2012 may be used to fix the optical touch component 302.

[0117] It should be noted that the second connector 2012 may include a third connecting portion fixed to the side of the plate portion 201 facing the enclosing portion 202, and a fourth connecting portion fixed to the side of the enclosing portion 202 facing the plate portion 201. The two sides of the optical touch assembly 302, which are positioned opposite each other in the third direction Z, can be fixedly connected to the third connecting portion and the fourth connecting portion, respectively. Figure 9 The labels for the third and fourth connecting portions are not shown in the diagram; their labels will be used in subsequent embodiments. Figure 17 As shown in the figure, the second connector 2012 may have a second mounting groove S2 for mounting the optical touch assembly 302. The second mounting groove S2 may be located between the third connecting portion and the fourth connecting portion. The optical touch assembly 302 may be fixed in the second mounting groove S2, so that the optical touch assembly 302 can be fixed on the second connector 2012.

[0118] like Figure 7As shown, in the prior art, water droplets that enter the frame body 200 through the first seam P1 can flow along the second water flow path B2 on the inner surface of the frame body 200 to the end of the second mounting groove S2 located on the plate part 201. As a result, since the display device is not installed horizontally, the water droplets flowing to the end of the second mounting groove S2 may flow into the second mounting groove S2, thereby causing corrosion to the optical touch component 302.

[0119] In this application, as Figure 6 and Figure 9 As shown, when the water guiding structure 203 includes a first water guiding channel K1, the water guiding structure 203 may further include a second water guiding channel K2. The second water guiding channel K2 of the water guiding structure 203 can communicate with the first water guiding channel K1, and in the first direction X, the second water guiding channel K2 can be located between the first water guiding channel K1 and the second connecting member 2012. Here, the second water guiding channel K2 may also have a certain depth in the third direction X, and a first width in the first direction X. For example, in the third direction Z, the depth of the second water guiding channel K2 is the same as the depth of the first water guiding channel K1.

[0120] Optionally, in the first direction X, the end of the optical touch component 302 may protrude beyond the end face of the second connector 2012. The orthographic projection of the protruding portion of the optical touch component 302 relative to the second connector 2012 onto the plate portion 201 may lie within the area where the second water guide groove K2 is located. That is, the second water guide groove K2, located between the first water guide groove K1 and the second connector 2012 in the first direction X, can disrupt a certain length of the second connector 2012, allowing water droplets flowing along the second water flow path B2 to flow within the second water guide groove K2 and be blocked by the groove surface of the second water guide groove K2 facing the second connector 2012, thus preventing water droplets from flowing into the second mounting groove S2 and causing erosion to the optical touch component 302.

[0121] Optional, such as Figure 9 As shown, the second connector 2012 in the frame body 200 may include a first rib 2012a and a second rib 2012b disposed opposite to each other in the second direction Y. The first rib 2012a in the second connector 2012 may be closer to the filter strip 302 relative to the second rib 2012b, and a portion of the groove in the second mounting groove S2 is provided between the first rib 2012a and the second rib 2012b. Here, the first rib 2012a and the second rib 2012b may be fixed to the side of the plate portion 201 facing the enclosing portion 202, that is, the third connecting portion in the second connector 2012 may include the first rib 2012a and the second rib 2012b, and the third connecting portion may have a portion of the groove in the second mounting groove S2.

[0122] In this application, since the second water guide channel K2 is located on the side of the plate portion 201 facing the enclosure portion 202, the second water guide channel K2 is located between the first water guide channel K1 and the third connecting portion of the second connector 2012. The second water guide channel K2 can penetrate through the first rib 2012a and the second rib 2012b to damage the end of the third connecting portion in the second connector 2012. In this way, water droplets flowing along the second water flow path B2 can flow into the second water guide channel K2 and will not flow to the end of the groove in the second mounting groove S2 located on the third connecting portion, thereby preventing corrosion of the optical touch component 302 along the groove.

[0123] Optional, such as Figure 6 and Figure 9 As shown, in the extending direction of the first water guide channel K1, the length of the second water guide channel K2 of the frame body 200z can be less than the length of the first water guide channel K1. That is, the length of the second water guide channel in the second direction Y can be less than the length of the first water guide channel K1 in the second direction Y. Therefore, when the first water guide channel K1 penetrates the frame body 200 in the second direction Y, the second water guide channel will not penetrate the frame body 200 in the second direction Y. In this way, water droplets flowing into the second water guide channel can first flow into the first water guide channel K1, and then flow through the first water guide channel K1 to the outside of the frame body 200.

[0124] Optional, please refer to Figure 10 , Figure 10 This is a partial enlarged view of another optical touch frame provided in an embodiment of this application. The optical touch frame may further include a first water-absorbing portion 400, at least a portion of which may be located within a first water-guiding groove K1. In this way, the first water-absorbing portion 400 can directly absorb water droplets flowing into the first water-guiding groove K1, further reducing the possibility of the optical touch component 302 being corroded by moisture.

[0125] It should be noted that, on the third direction Z, the thickness of the first water-absorbing part 400 can be greater than the groove depth of the first clearance groove K1, and in order to ensure that the first water-absorbing part 400 can absorb more water, the thickness of the first water-absorbing part 400 can be greater than or equal to 4 mm.

[0126] Optionally, the first water-absorbing portion 400 in the optical touch frame can contact the end face of the filter strip 301. In this way, water droplets flowing onto the end face of the filter strip 301 can be directly absorbed by the first water-absorbing portion 400, avoiding the possibility that water droplets flowing onto the end face of the filter strip 301 may flow along the inner surface of the frame body 200 onto the optical touch component 302, further reducing the possibility of the optical touch component 302 being corroded by moisture.

[0127] It should be noted that, in the first direction X, the width of the first water-absorbing part 400 can be less than or equal to the width of the first water-guiding groove K1, thus ensuring that the first water-absorbing part 400 can be located within the first water-guiding groove K1. Furthermore, even when the width of the first water-absorbing part 400 in the first direction X is less than the width of the first water-guiding groove K1 in the first direction X, the first water-absorbing part 400 still needs to contact the end face of the filter strip 301 to ensure that the first water-absorbing part 400 can directly absorb water flowing to the end face of the filter strip 301.

[0128] Please refer to the following in this application: Figure 11 and Figure 12 , Figure 11 This is a partially enlarged view of an optical touch bezel provided in another embodiment of this application. Figure 12 This is a partial enlarged view of another optical touch frame without optical touch components provided in the embodiments of this application. The water guiding structure 203 on the plate body 201 may include: a third water guiding groove K3.

[0129] The orthographic projection of the optical touch component 302 onto the plate portion 201 can overlap with the area where the third water guide channel K3 is located. Here, the third water guide channel K3 is located on the side of the plate portion 201 facing the enclosing portion 202, and the third water guide channel K3 can penetrate at least a portion of the second rib 2012b and the first rib 2012a. In this way, water droplets entering the second mounting groove S2 from the end of a portion of the groove on the plate portion will flow to the position of the third water guide channel K3 and fall directly into the third water guide channel K3, flowing within the third water guide channel K3. Thus, the third water guide channel K3 can prevent water droplets from flowing within the second mounting groove S2, thereby preventing water droplets from corroding the optical touch component 302.

[0130] It should be noted that water droplets flowing through the second water flow path B2 to the end of a portion of the groove located on the plate part of the second mounting groove S2 can flow along the gap between the second rib 2012b and the optical touch component 302, or along the gap between the first rib 2012a and the optical touch component 302. Thus, the fact that the third water guide groove K3 completely penetrates the second rib 2012b ensures that water droplets flowing through the gap between the second rib 2012b and the optical touch component 302 can fall into the third water guide groove K3, and the portion of the third water guide groove K3 penetrating the first rib 2012a ensures that water droplets flowing through the gap between the first rib 2012a and the optical touch component 302 can fall into the third water guide groove K3.

[0131] Optional, such as Figure 11 and Figure 12As shown, the water guiding structure 203 located on the plate portion 201 may further include: a first water guiding groove K1, wherein the orthographic projection of the optical touch component K1 on the plate portion 201 does not coincide with the area where the first water guiding groove K1 is located. The end of the second mounting groove S2 of the second connector 2012 may communicate with the first water guiding groove K1. The optical touch component 302 may include: a circuit board 3021, and a target device connected to the circuit board 302, wherein the circuit board 3021 in the optical touch component 302 is mounted in the second mounting groove S2. In the first direction X, the third water guiding groove K3 may be located between the first water guiding groove K1 and the target device. This ensures that water droplets entering the second mounting groove S2 will flow into the third water guiding groove K3 before flowing to the target device and be blocked by the third water guiding groove K3, preventing them from continuing to flow to the target device and ensuring that the target device is not corroded by water.

[0132] It should be noted that the target device in the optical touch assembly 302 is the outermost component in the first direction X among the multiple components connected to the circuit board 3021 in the optical touch assembly 302. For example, the target device in the optical touch assembly 302 is a terminal. Here, the multiple components connected to the circuit board 3021 in the optical touch assembly 302 are important components in the optical touch assembly 302 used to implement the touch function, such as infrared emitting elements, infrared receiving elements, and terminals. Providing a third water guide channel K3 between the target device and the first water guide channel K1 ensures that the multiple components in the optical touch assembly 302 used to implement the touch function are not corroded by moisture, thereby ensuring that the optical touch assembly 302 can normally perform its touch function.

[0133] For example, in the first direction X, the distance between the surface of the third water guide channel K3 facing the first water guide channel K1 and the surface of the first water guide channel K1 facing the second connector 2012 can be greater than or equal to zero and less than or equal to 3 mm. Here, the third water guide channel K3 is always located between the first water guide channel K1 and the target device.

[0134] When the distance between the surface of the third water guide channel K3 facing the first water guide channel K1 and the surface of the first water guide channel K1 facing the second connector 2012 is zero, the third water guide channel K3 can be directly connected to the first water guide channel K1. In this case, the water droplets flowing through the second water flow path B2 can flow directly into the third water guide channel K3 before flowing to the end of the second mounting groove S2, so as to avoid the flow of water droplets in the second mounting groove S2.

[0135] When the distance between the surface of the third water guide channel K3 facing the first water guide channel K1 and the surface of the first water guide channel K1 facing the second connector 2012 is greater than zero and less than or equal to 3 mm, the water droplets flowing to the end of the second mounting groove S2 through the second water flow path B2 will first flow along the second mounting groove S2, and after flowing to the position where the second mounting groove S2 and the third water guide channel K3 are connected, they can fall into the third water guide channel K3 to prevent the water droplets from continuing to flow in the second mounting groove S2.

[0136] Optional, such as Figure 11 and Figure 12 As shown, the frame body 200 in the optical touch frame may further include a partition plate 204. The partition plate 204 in the frame body 200 may be located between the plate portion 201 and the enclosure portion 202 in the third direction Z, and is fixedly connected to the plate portion 201 and the enclosure portion 202. The partition plate 204 is used to divide the accommodating space D of the frame body 200 into a first cavity D1 and a second cavity D2 arranged in the second direction Y, and the first cavity D1 is closer to the filter strip 301 than the second cavity D2. The optical touch assembly 302 may be located in the first cavity D1. The orthographic projection of the third water guide groove K3 of the water guide structure 203 on the plate portion 201 may overlap with the orthographic projection of the partition plate 204 on the plate portion 201, that is, the third water guide groove K3 may also penetrate the partition plate 204.

[0137] In this way, water droplets flowing from the second mounting groove S2 into the third water guide groove K3 can flow along the third water guide groove K3 past the partition plate 204 to flow into the second cavity D2, preventing water droplets from accumulating in the first cavity D1 containing the optical touch component 302, and further reducing the possibility of the optical touch component 302 being corroded by moisture. Here, in the second direction Y, the third water guide groove K3 can penetrate through the partition plate 204, and the length of the third water guide groove K3 in the second direction Y can be less than the length of the first water guide groove K1 in the second direction Y. In this way, water droplets located in the third water guide groove K3 can flow out of the third water guide groove K3 after accumulating to a certain extent, and then flow out of the frame body 200 through the first water guide groove K1.

[0138] Please refer to the following in this application: Figure 13 , Figure 13This is a partially enlarged view of another optical touch frame provided in another embodiment of this application. When the enclosing portion 202 in the frame body 200 has a water-guiding structure 203 on the side facing away from the plate portion 201, to prevent water droplets from eroding the optical touch component 302, the water-guiding structure 203 may include a water-blocking groove H. Specifically, in the first direction X, the distance between the water-blocking groove H and the end of the enclosing portion 202 can be less than the distance between the water-blocking groove H and the midpoint of the enclosing portion 202; that is, the water-blocking groove H can be located near the end of the enclosing portion 202 in the first direction X. Here, the distance between the side of the water-blocking groove H facing the end of the enclosing portion 202 in the first direction X and the end of the enclosing portion 202 can be less than or equal to 30 mm.

[0139] In this way, when water droplets are present on the side of the enclosure 202 facing away from the plate 201, the water-blocking groove H can prevent the water droplets from flowing towards the end of the enclosure 202, thereby preventing water droplets from flowing into the receiving space D through the end of the enclosure 202. This reduces the possibility of moisture erosion of the optical touch component 302 and improves the reliability of the display device with the optical touch frame installed.

[0140] Optional, such as Figure 14 As shown, Figure 14 This is a partially enlarged view of another optical touch frame provided in another embodiment of this application. The water-blocking groove H may include: a first groove H1 and a second groove H2 that are connected. The extension direction of the first groove H1 may be parallel to a third direction Z, and the extension direction of the second groove H2 may be parallel to a second direction Y. In the second direction Y, the first groove H1 is closer to the filter strip 301 than the second groove H2. In this way, the extension direction of the second groove H2 is parallel to the direction of gravity, so after water droplets accumulate in the water-blocking groove H, the water droplets can flow along the water-blocking groove H under the action of gravity.

[0141] Optional, such as Figure 14As shown, the enclosing portion 202 in the frame body 200 may include a first plate 2021, a second plate 2022, and a third plate 2023 connected in sequence. The second plate 2022 is disposed opposite to the plate portion 201 in the third direction Z, and the first plate 2021 and the third plate 2023 are disposed opposite to each other in the second direction Y. In the second direction Y, the first plate 2021 is closer to the filter strip 301 than the third plate 2023. A first connector 2011 may be provided between the side of the first plate 2021 away from the second plate 2022 and the plate portion 201, and the side of the third plate 2023 away from the second plate 2022 may be fixedly connected to the side of the plate portion 201 away from the first connector 2011. In this way, the first plate 2021, the second plate 2022, the third plate 2023, and the plate portion 201 can enclose an accommodating space D. The first groove H1 can be located on the side of the first plate 2021 that is away from the third plate 2023, and the second groove H2 can be located on the side of the second plate 2022 that is away from the plate part 201.

[0142] Optional, please refer to Figure 15 and Figure 16 , Figure 15 This is a partial schematic diagram of another optical touch bezel provided in another embodiment of this application. Figure 16 This is a partial exploded view of an optical touch frame provided in an embodiment of this application. The optical touch frame may further include a second water-absorbing part 500. The second water-absorbing part 500 may be located within a water-blocking groove H. In this way, water droplets flowing into the water-blocking groove H can be directly absorbed by the second water-absorbing part 500, thereby preventing corrosion of the optical touch component due to the arbitrary flow of water droplets.

[0143] Optionally, the second water-absorbing portion 500 may include a first portion 501 and a second portion 502 connected together. At least a portion of the first portion 501 may be located within the water-blocking groove H, and the second portion 502 may contact the side of the filter strip 301 facing the enclosure portion 202 in the third direction Z. In this way, water droplets gathered on the filter strip 301 can be directly absorbed by the second portion 502 of the second water-absorbing portion 500, preventing water droplets from flowing along the filter strip 301 to the end of the filter strip 301 and into the receiving space D of the frame body 201. This prevents water droplets from corroding the optical touch component 302 located in the receiving space D, thereby improving the reliability of the optical touch component 302.

[0144] Here, in the display device, the second portion 502 of the second water-absorbing part 500 can be located between the filter strip 301 and the display panel 100. In this way, during the use of the display device, the second portion 502 of the second water-absorbing part 500 can absorb the water that accumulates between the filter strip 301 and the display panel 100, so as to prevent water droplets from flowing along the filter strip 301 to the end of the filter strip 301.

[0145] It should be noted that, in the first direction X, the distance between the side of the second water-absorbing part 500 facing the end of the frame body 200 and the end face of the second connector 1021 can be less than or equal to 30 mm. Here, when the distance between the side of the second water-absorbing part 500 facing the end of the frame body 200 and the end face of the second connector 1021 is zero, the second water-absorbing part 500 can absorb all the moisture located between the filter strip 301 and the display panel 100. When the distance between the side of the second water-absorbing part 500 facing the end of the frame body 200 and the end face of the second connector 1021 is greater than zero and less than or equal to 20 mm, the moisture located between the end faces of the second water-absorbing part 500 and the second connector 1021 can flow to the end face of the filter strip 301, and in this case, it is ensured that the moisture flowing to the end face of the filter strip 301 is not excessive and will not drip onto the optical touch assembly 302.

[0146] Optionally, the depth of the water-blocking groove H can be greater than or equal to the thickness of the first part 501. In this way, after the second water-absorbing part 500 is full of water, the water overflowing from the second water-absorbing part 500 can be blocked by the water-blocking groove H to prevent water droplets from flowing along the outside of the frame body 200 to the inside of the frame body 200, further reducing the possibility of the first infrared touch circuit board being corroded by water.

[0147] Please refer to the following in this application: Figure 17 , Figure 17 This is a partial enlarged view of a display device provided in an embodiment of this application. The filter strip 301 and the optical touch component 302 in the optical touch bezel can be arranged in the second direction Y, and the filter strip 301 can be closer to the display panel 100 in the display device than the optical touch component 302.

[0148] It should be noted that, as Figure 17As shown, in the third direction Z, the first connector 2011 in the frame body 200 may include: a first connecting portion 2011a and a second connecting portion 2011b disposed opposite to each other. The first connecting portion 2011a can be fixedly connected to the side of the plate portion 201 facing the enclosure portion 202, and the second connecting portion 2011b can be fixedly connected to the side of the enclosure portion 202 facing the plate portion 201. The two sides of the filter strip 301 disposed opposite to each other in the third direction Z can be fixedly connected to the first connecting portion 2011a and the second connecting portion 2011b respectively. Since there is a gap communicating with the accommodating space D between the first connecting portion 2011a and the second connecting portion 2011b in the first connector 2011, and the filter strip 301 located between the first connecting portion 2011a and the second connecting portion 2011b is located within this gap, it is ensured that the infrared rays emitted by the optical touch component 302 located in the accommodating space D are emitted after passing through the filter strip 301.

[0149] Similarly, such as Figure 17 As shown, in the third direction Z, the second connector 2012 in the frame body 200 may include a third connecting portion 20121 and a fourth connecting portion 20122 disposed opposite to each other. The third connecting portion 20121 may be fixedly connected to the side of the plate portion 201 facing the enclosure portion 202, and the fourth connecting portion 20122 may be fixedly connected to the side of the enclosure portion 202 facing the plate portion 201. The two sides of the optical touch component 302 that are relatively distributed in the third direction Z may be fixedly connected to the third connecting portion 20121 and the fourth connecting portion 20124, so that the optical touch component 302 can be fixed in the accommodating space D.

[0150] Here, since the water droplets on the front of the display device flow along the inner surface of the plate portion 201, the water droplets flowing along the second water flow path B2 will flow to the end of the second mounting groove S2 located on the plate portion 201, so as to erode the entire optical touch assembly 302 through the portion located in the second mounting groove S2. For this reason, the first water guide groove K1, the second water guide groove K2, and the third water guide groove K3 in the above embodiment for preventing water droplets from eroding the optical touch assembly 302 are all located on the side of the plate portion 201 facing the enclosure portion 202.

[0151] In summary, this application provides an optical touch bezel, including a bezel body and an optical touch component. The side of the bezel body facing the enclosure portion, and / or the side of the enclosure portion facing away from the bezel body, may have a water-guiding structure. Here, the water-guiding structure on the bezel body can be located within the receiving space of the bezel body, allowing water droplets entering the bezel body to flow under the action of the water-guiding structure, thus preventing water droplets from flowing onto the optical touch component. The water-guiding structure on the enclosure portion can be located outside the receiving space of the bezel body, allowing some water droplets on the side of the enclosure portion facing away from the bezel body to flow under the action of the water-guiding structure, preventing water droplets from flowing into the bezel body and thus preventing water droplets from flowing onto the optical touch component. This reduces the possibility of the optical touch component being corroded by moisture and improves the reliability of the display device equipped with this optical touch bezel.

[0152] This application also provides an optical touch frame, please refer to... Figure 18 , Figure 18 This is a partial enlarged view of an optical touch frame provided in another embodiment of this application. The optical touch frame may include: a frame body 200, an optical touch component 302, a filter strip 301, and a second water-absorbing part 500.

[0153] The extension direction of the frame body 200 is parallel to the first direction X. The frame body 200 includes a plate portion 201 and an enclosing portion 202 disposed opposite to each other in the third direction Z. There is an accommodating space D between the plate portion 201 and the enclosing portion 202. The first direction X and the third direction Z intersect.

[0154] An optical touch component 302 is installed within the receiving space D. A filter strip 301 is installed between the plate portion 201 and the enclosing portion 202, and the filter strip 301 and the optical touch component 302 are arranged in the second direction Y. The second direction Y intersects the first direction X and the third direction Z.

[0155] The second water-absorbing portion 500 is located near the end of the enclosure portion 202 in the first direction X. At least a portion of the second water-absorbing portion 500 can contact the side of the filter strip 301 facing the enclosure portion 202 in the third direction Z. In this way, water droplets gathered on the filter strip 301 can be absorbed by the portion of the second water-absorbing portion 500 that contacts the enclosure portion 202, so as to prevent water droplets from flowing along the filter strip 301 to the end of the filter strip 301 and into the receiving space D of the frame body 201. This prevents water droplets from corroding the optical touch component 302 located in the receiving space D and improves the reliability of the optical touch component 302.

[0156] This application embodiment also provides a display device, which can be the display device in the above embodiments, as shown in the figures and... Figure 2As shown, the display device may include a first optical touch frame 701 and a display panel 100. The first optical touch frame 701 in the display device may be the optical touch frame in the above embodiment, and the first optical touch frame 701 in the display device may be fixedly connected to the ground side of the display panel 100. The extending direction of the first optical touch frame 701 is parallel to the first direction X.

[0157] Optionally, the display device may further include: a second optical touch bezel 702, and two opposing third optical touch bezels 703. The first optical touch bezel 701 is fixedly connected to the ground side of the display panel 100, the second optical touch bezel 702 can be connected to the upper side of the display panel 100, and the two third optical touch bezels 703 can be connected to the left and right sides of the display panel 100, respectively. Here, the extension direction of the second optical touch bezel 702 is parallel to the first direction X, and the extension direction of the two third optical touch bezels 703 is parallel to the second direction Y.

[0158] Optional, such as Figure 19 As shown, Figure 19 This is a partially enlarged top view of a display device provided in an embodiment of this application. A gap exists between the optical touch component 7031 in the third optical touch frame 703 and the filter strip 301 in the first optical touch frame 701. Thus, during use, if the display device shakes, the filter strip 301 in the first optical touch frame 701 will not interfere with the optical touch component 7031 in the third optical touch frame 703, thereby preventing damage to the optical touch component 7031 in the third optical touch frame 703. For example, in the first direction X, the length L2 of the gap between the end faces of the optical touch component 7031 in the third optical touch frame 703 and the filter strip 301 in the first optical touch frame 701 can be greater than or equal to 0.5 mm.

[0159] Optional, such as Figure 2 As shown, there is a first gap between the end face of the filter strip 7031 in the third optical touch frame 703 and the side of the filter strip 301 in the first optical touch component 701 that is away from the optical touch component. This first gap is the second seam P2 in the above embodiment.

[0160] Optional, such as Figure 2 As shown, there is a second gap between the end face of the frame body 7032 in the third optical touch frame 703 and the side of the frame body 200 in the first optical touch assembly 701 facing the display panel 100. This second gap is the first seam P1 in the above embodiment.

[0161] When water droplets are present on the front of the display device, the water droplets can enter the interior of the frame body 200 in the first optical touch frame 701 through the first and second gaps, causing corrosion to the optical touch component 302 located inside the frame body 200. The water-guiding structure in the first optical touch frame 701 can prevent water droplets from flowing towards the optical touch component 302, thereby reducing the possibility of water corrosion of the optical touch component 302, improving the reliability of the optical touch component 302, and consequently improving the reliability of the display device.
