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 an infrared touch circuit board. The support frame surrounds the four sides of the display screen to support it. The infrared touch circuit board is located within the support frame on the display side of the screen. The infrared touch circuit 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 system 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. When wiping the infrared touch display device, water droplets can enter the support frame through the seams and corrode the infrared touch circuit board, resulting in low reliability of the infrared touch display device.

[0056] 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.

[0057] This application provides an optical touch bezel for mounting in a display device to enable the display device to have touch functionality.

[0058] Please refer to this. Figure 1 , Figure 1 This is a front view of the display surface 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.

[0059] 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.

[0060] 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.

[0061] 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 As shown, Figure 2 This is a schematic diagram of the structure of a display device provided in an embodiment of this application. The frame body in the third optical touch frame 703 can be the frame body 200, and the optical touch component in the third optical touch frame 703 can be the optical touch component 301.

[0062] The frame bodies of the first optical touch frame 701, the second optical touch frame 702, and the two third optical touch frames 703 can be used to support the display panel 100 to realize the assembly of the display device. The optical touch components of the first optical touch frame 701, the second optical touch frame 702, and the two third optical touch frames 703 can be used to realize the touch function of the display device.

[0063] 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.

[0064] It should be noted that 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 spliced ​​together. Therefore, after the display device is assembled, there are seams on the surface of the display device. When water droplets are present on the surface of the display device, these droplets may flow into the interior of the frame body through these seams. After water enters the interior of the frame body 200 of the third optical touch frame 703, the water droplets inside may flow onto the optical touch component 301 located within the frame body 200, causing corrosion and resulting in lower reliability of the optical touch component 301, which in turn leads to lower reliability of the display device.

[0065] To prevent the optical touch component 200 in the third optical touch bezel 703 from being corroded by moisture, this application embodiment provides an optical touch bezel, which can be the third optical touch bezel in a display device. The optical touch bezels in the following embodiments are all third optical touch bezels in display devices.

[0066] like Figure 2 and Figure 3 As shown, Figure 3 This is a partial enlarged view of an optical touch frame provided in an embodiment of this application. The optical touch frame may include a frame body 200 and an optical touch component 301. Since the extension direction of the optical touch frame is parallel to the second direction Y, the extension direction of the frame body 200 in the optical touch frame may be parallel to the second direction Y.

[0067] The frame body 200 in the optical touch bezel may include a plate portion 201 and an enclosing portion 202 disposed opposite to each other in a third direction Y. A receiving space D may exist between the plate portion 201 and the enclosing portion 202 in the frame body 200. Here, the third direction Z may intersect with the second direction Y; for example, the third direction Z may intersect perpendicularly with the second direction Y. It should be noted that after the optical touch assembly 300 is installed in the display device, the third direction Z may be a direction perpendicular to the display surface of the display panel 100 in the display device, and the second direction Y may be parallel to the display surface of the display panel 100 in the display device.

[0068] The receiving space D in the frame body 200 may have a first mounting groove K, which can be used to mount the optical touch component 301. In the prior art, after water enters the receiving space D of the frame body 200, the water droplets entering the frame body 200 may flow into the first mounting groove K, and then flow onto the optical touch component 301, which may cause the optical touch component 301 to be damaged by the water droplets, resulting in low reliability of the optical touch component 301.

[0069] In this application, as Figure 3 and Figure 4 As shown, Figure 4 This is a schematic diagram of an optical touch bezel without an optical touch component, provided in an embodiment of this application. The interior of the accommodating space D of the bezel body 200 may also have a water channel H. The extension directions of both the first mounting groove K of the bezel body 200 and the water channel H can be parallel to the second direction Y. In this way, water droplets entering the interior of the bezel body 200 and flowing to the vicinity of the first mounting groove K can flow into the water channel H, thereby preventing water droplets from flowing into the first mounting groove K and corroding the optical touch component 301. This reduces the possibility of the optical touch component 301 being corroded by moisture and improves the reliability of the display device on which the optical touch component 301 is installed.

[0070] In summary, this application provides an optical touch bezel, including a bezel body and an optical touch component, wherein the optical touch component is mounted in a first mounting groove of the bezel body. The bezel body also has a water-guiding groove inside, and the extension direction of the water-guiding groove and the extension direction of the first mounting groove can both be parallel to a second direction. This allows water droplets entering the bezel body and flowing around the first mounting groove to flow into the water-guiding groove, preventing water droplets from flowing into the first mounting groove and corroding the optical touch component. This reduces the possibility of moisture corrosion of the optical touch component and improves the reliability of the display device equipped with the optical touch component.

[0071] Optional, such as Figure 4 and Figure 5 As shown, Figure 5 This is a partial cross-sectional view of an optical touch frame provided in an embodiment of this application. The first mounting groove K of the frame body 200 may include a first strip groove K1 and a second strip groove K2 arranged in the third direction Z. The two opposite sides of the optical touch component 301 in the third direction Z can be respectively snapped into the first strip groove K1 and the second strip groove K2, thereby realizing the installation of the optical touch component 301 inside the frame body 200.

[0072] Here, the water inlet channel H and the first strip channel K1 can both be located on the side of the plate portion 201 facing the enclosing portion 202, and the second strip channel K2 can be located on the side of the enclosing portion 202 facing the plate portion 201.

[0073] It should be noted that after the optical touch component is installed in the display device and connected to the left or right side of the display panel in the display device, in the third direction Z, the display panel in the display device can be located on the side of the plate portion 201 of the frame body 200 of the optical touch component facing the enclosure portion 202. Here, during the display of the screen, the side of the screen displayed that the user can observe can be the front of the display device, and correspondingly, the side opposite to the front of the display device in the third direction Z can be the back of the display device. In this way, the plate portion 201 can be located on the front of the display device in the third direction Z.

[0074] During the use of the display device, water droplets tend to condense on the front of the display device. For example, users often use a damp towel to wipe the front of the display device to keep the surface clean. As a result, a large number of water droplets enter the bezel body 200 from the seam on the front of the display device. The first strip groove K1, which is located on the side of the plate portion 201 facing the enclosure portion 202, is more prone to water droplets entering.

[0075] Therefore, both the water inlet H and the first strip-shaped groove K1 are located on the side of the plate portion 201 facing the enclosure portion 202, so that water droplets flowing around the first strip-shaped groove K1 can flow into the water inlet H, thereby preventing water droplets from flowing into the first strip-shaped groove K1 and corroding the optical touch component 301. This reduces the possibility of the optical touch component 301 being corroded by moisture and improves the reliability of the display device.

[0076] Optionally, after installing the optical touch component into the display device so that it connects to the left or right side of the display panel in the display device, please refer to... Figure 2 , Figure 6 and Figure 7 , Figure 6 This is a partial enlarged view of a display device provided in an embodiment of this application. Figure 7 This is a partial exploded view of a display device provided in an embodiment of this application. The second optical touch bezel 702 in the display device may include: a main bezel portion 7021, and a connecting plate 7022 connected to the end of the main bezel portion 7021. The connecting plate 7022 can be spliced ​​with the end of the bezel body 200 in the first optical touch bezel 701 in the second direction Y. Here, the first optical touch bezel 701 in the display device is the optical touch bezel in this application.

[0077] The display device may further include a first corner block 400, at least a portion of which may be located on the connecting plate 7022, and the first corner block 400 is used to connect the end of the frame body 200 and the end of the second optical touch frame 702, so that the frame body 200 and the second optical touch frame 702 can be connected together by the first corner block 400. Here, there is a first gap P1 between the first corner block 400 and the frame body 200, and a second gap P2 between the first corner block 400 and the connecting plate 7022.

[0078] It should be noted that, ideally, after the display device is installed, the second direction Y can be parallel to the direction of gravity, and the first direction X can be perpendicular to the direction of gravity, so that the length direction of the second optical touch component 702 is horizontal, that is, the display device can be installed horizontally. However, due to installation errors, the first direction X will not be perpendicular to the direction of gravity, resulting in the display device not being installed horizontally. Therefore, if the display device is not installed horizontally, water droplets on the outer surface of the display device will enter the frame body 200 through the first gap P1. Under the action of gravity, the water droplets will flow along the first flow path B1 into the first mounting groove B1, causing corrosion to the optical touch component 301.

[0079] Furthermore, after the display device is installed, under ideal installation conditions, the second direction Y can be parallel to the direction of gravity. Even if the display device is not installed horizontally, water droplets from the second gap P2 into the inside of the bezel 200 will flow towards the end of the bezel body 200 under the action of gravity, and then the water droplets will flow along the second flow path B2 into the first strip groove K1, thereby eroding the optical touch component 301.

[0080] In this application, water droplets entering the frame body 200 through the first gap P1 will flow along the first flow path B1 to the first mounting groove K, and water droplets entering the frame body 200 through the second gap P2 will flow along the second flow path B2 to the first mounting groove K. Therefore, the distribution of the water inlet groove H of the frame body 200 can have the following three optional implementation methods.

[0081] In this application, as Figure 5 and Figure 8 As shown, Figure 8 This is a partial enlarged view of another optical touch frame provided in the embodiments of this application. The optical touch frame may also include a filter strip 302 fixed on the frame body 200. The infrared light emitted by the optical touch component 301 in the optical touch frame can be emitted after passing through the filter strip 302 to form an infrared detection network on the display panel.

[0082] In the first optional implementation, to prevent water droplets entering the frame body 200 through the first gap P1 from flowing along the first flow path B1 into the first mounting groove K, the water guide groove H and the first strip groove K1 may not be connected, and the first strip groove K1 may be closer to the filter strip 302 in the first direction X relative to the water guide groove H. Thus, if water droplets entering the frame body 200 through the first gap P1 flow towards the filter strip 302 in the first direction X, because the first strip groove K1 is closer to the filter strip 302 in the first direction X relative to the water guide groove H, the water droplets will flow directly into the water guide groove H. In this way, the water guide groove H can prevent the water droplets from flowing towards the first strip groove K1.

[0083] Optional, such as Figure 8 and Figure 9 As shown, Figure 9This is a partial cross-sectional view of another optical touch frame provided in this application embodiment. The frame body 200 may further include a first rib 2011 and a second rib 2012 arranged in the first direction X. The first rib 201 and the second rib 202 in the frame body 200 are both fixed to the side of the plate portion 201 facing the enclosing portion 202. A first strip groove K1 may be formed between the first rib 2011 and the second rib 2012, and the second rib 2012 may be closer to the filter strip 302 in the first direction X relative to the first rib 2011. The side of the first rib 2011 facing away from the second rib 2012 has a water channel H, so that the first strip groove K1 may be closer to the filter strip 302 in the first direction X relative to the water channel H.

[0084] It should be noted that in the prior art, the frame body 200 does not have a water channel H inside. Therefore, if the display device is not installed horizontally after installation, water droplets entering through the first gap P1 will flow towards both the second direction Y and the first direction X under the influence of gravity, eventually overflowing the first rib 2011 and entering the first strip-shaped groove K1. To address this, in this application, a water channel H is provided on the side of the first rib 2011 facing away from the second rib 2012. This ensures that water droplets flowing through the first gap P1 and towards the first rib 2011 in the first direction X will flow directly into the water channel H, preventing them from overflowing the first rib 2011 and flowing into the first strip-shaped groove K1.

[0085] In the second optional implementation, to prevent water droplets entering the frame body 200 through the second gap P1 from flowing along the first flow path B1 into the first mounting groove K, as follows: Figure 5 and Figure 10 As shown, Figure 10 This is a partial cross-sectional view of another optical touch frame provided in the embodiments of this application, wherein the water channel H can be connected to the first strip channel K1.

[0086] It should be noted that in existing technologies, such as Figure 11 As shown, Figure 11 This is a partial cross-sectional view of an optical touch frame in the prior art. Water droplets that enter the frame body 200 through the second gap P2 will flow to the end face of the frame body 200 facing the second optical touch component 702, and then flow through the end face to the first strip groove K1. The water droplets that enter will spread through the portion of the optical touch component 301 located in the first strip groove K1 to the optical touch component 301, thereby causing erosion to the optical touch component 301.

[0087] In this application, such as Figure 10As shown, water droplets flowing through the second gap P2 to the end face of the frame body 200 facing the second optical touch component 702 will flow into the water channel H through this end face, and thus will not spread to the optical touch component 301. In this way, the water channel H can block the flow of water droplets toward the first strip-shaped channel K1.

[0088] Optional, such as Figure 10 As shown, the water inlet tank H may include a first sub-tank H1 and / or a second sub-tank H2. Here, the first sub-tank H1 may be connected in the first direction X to the side of the first strip-shaped tank K1 that is further away from the filter strip 302. The second sub-tank H2 may be connected in the first direction X to the side of the first strip-shaped tank K1 that is closer to the filter strip 302.

[0089] That is, when the water inlet channel H is connected to the first strip channel K1, the water inlet channel H can have the following three states:

[0090] In the first case, the water channel H may only include the first sub-channel H1. The first sub-channel H1 may be further away from the filter strip 302 in the first direction X relative to the first strip channel K1. Water droplets flowing through the second gap P2 to the end face of the frame body 200 facing the second optical touch component 702 will flow into the first sub-channel H1 through this end face.

[0091] In the second case, the water channel H may only include the second sub-channel H2. The second sub-channel H2 may be closer to the filter strip 302 in the first direction X relative to the first strip channel K1. Water droplets flowing through the second gap P2 to the end face of the frame body 200 facing the second optical touch component 702 will flow into the second sub-channel H2 through this end face.

[0092] In the third case, the water channel H may include a first sub-channel H1 and a second sub-channel H2. The first sub-channel H1 and the second sub-channel H2 may be distributed on both sides of the first strip channel K1 in the first direction X. Water droplets that flow through the second gap P2 to the end face of the frame body 200 facing the second optical touch component 702 will flow into the first sub-channel H1 and the second sub-channel H2 through this end face.

[0093] Optional, such as Figure 10 As shown, similarly, the interior of the frame body 200 may have a first rib 2011 and a second rib 2012 arranged in the first direction X. A first strip-shaped groove K1 may be provided between the first rib 2011 and the second rib 2012 in the frame body 200, and the second rib 2012 may be closer to the filter strip 302 in the first direction X than the first rib 2011.

[0094] The first rib 2011 may have a first sub-groove H1 on the side facing the second rib 2012, and / or the second rib 2012 may have a second sub-groove H2 on the side facing the first rib 2011. Thus, the frame body 200 may have a first sub-groove H1 that is further away from the filter strip 302 in the first direction X relative to the first strip groove K1, and / or a second sub-groove H2 that is closer to the filter strip 302 in the first direction X relative to the second strip groove K2.

[0095] In the third optional implementation, the interior of the frame body 200 can have multiple water channels, which may include a first water channel and a second water channel. Here, the first water channel can be the water channel in the first optional implementation, and the second water channel can be the water channel in the second optional implementation. The structures of the first and second water channels will not be described in detail here. In this way, in the third optional implementation, water droplets entering the interior of the frame body 200 through the first seam P1 and the second seam P2 will not flow onto the optical touch component 301.

[0096] In this application, as Figure 9 and Figure 10 As shown, the surface of the water channel H of the frame body 200 can be an arc-shaped channel. In this way, the water droplets flowing into the water channel H can eliminate surface tension under the action of the arc-shaped channel, so as to form a thin layer of water that flows along the water channel H. This ensures that the water flow in the water channel H will not flow to the optical touch component 301 in an undirected manner, further reducing the possibility of the optical touch component 301 being corroded by water.

[0097] Please refer to the following in this application: Figure 12 , Figure 12 This is a partial cross-sectional view of another optical touch frame provided in the embodiments of this application. The frame body 200 may include a connector 203 for fixing the filter strip 302. In the third direction Z, the connector 203 in the frame body 200 may include a first connecting portion 2031 and a second connecting portion 2032 disposed opposite to each other. The first connecting portion 2031 may be fixedly connected to the side of the plate portion 201 facing the enclosing portion 202, and the second connecting portion 2032 may be fixedly connected to the side of the enclosing portion 202 facing the plate portion 201. The two sides of the filter strip 302 disposed opposite to each other in the third direction Z may be fixedly connected to the first connecting portion 2031 and the second connecting portion 2032 respectively.

[0098] Here, there is a gap between the first connecting portion 2031 and the second connecting portion 2032 that communicates with the accommodating space D, and the filter strip 301 located between the first connecting portion 2031 and the second connecting portion 2032 is located in the gap, thus ensuring 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 302.

[0099] In summary, this application provides an optical touch bezel, including a bezel body and an optical touch component, wherein the optical touch component is mounted in a first mounting groove of the bezel body. The bezel body also has a water-guiding groove inside, and the extension direction of the water-guiding groove and the extension direction of the first mounting groove can both be parallel to a second direction. This allows water droplets entering the bezel body and flowing around the first mounting groove to flow into the water-guiding groove, preventing water droplets from flowing into the first mounting groove and corroding the optical touch component. This reduces the possibility of moisture corrosion of the optical touch component and improves the reliability of the display device equipped with the optical touch component.

[0100] This application also provides a display device, such as... Figure 2 As shown, the display device may include a third optical touch bezel 703 and a display panel 100. The third optical touch bezel in the display device is the optical touch bezel in the above embodiment. The third optical touch bezel in the display device may be connected to the left or right side of the display panel 100.

[0101] Optional, such as Figure 2 As shown, the display device further includes: a second optical touch frame 702, which is connected to the top side of the display panel 100, and the end of the second optical touch frame 702 is connected to the end of the third optical touch frame 703. The first mounting groove K inside the receiving space D of the third optical touch frame 703 includes: a first strip groove K1 and a second strip groove K2 arranged in the third direction Z.

[0102] like Figure 13 and Figure 14 As shown, Figure 13 This is a partial enlarged view of another display device improved according to the embodiments of this application. Figure 14 This is a partial top view of a display device provided in an embodiment of this application. The second optical touch component 702 in the frame 200 may have a first sliding groove K3 communicating with the first strip groove K1. Here, the connecting plate 2021 in the second optical touch component 702 for connecting to the end of the frame body 200 has the first sliding groove K3.

[0103] Here, in the first direction X, the width of the first sliding groove K3 can be greater than the width of the optical touch component 301, and the optical touch component 301 can be located within the first sliding groove K3 in the first direction X. Thus, if the optical touch component 301 is damaged during use of the display device, the operator can remove the first corner block 400 and pull the optical touch component 301 out of the first strip groove K1 via the first sliding groove K3. Similarly, after the optical touch component 301 is functioning normally, the operator can slide the optical touch component 302 into the first strip groove K1 via the first sliding groove K3. In this way, the first sliding groove K3 facilitates the installation and removal of the optical touch component 302.

[0104] In this application, as Figure 13 and Figure 14 As shown, the end of the optical touch component 301 can protrude from the frame body 200, and in the third direction Z, there can be a gap between the part of the optical touch component 301 protruding from the frame body 200 and the connecting plate 7022. In this way, when water droplets entering the frame 200 through the second gap P2 flow along the inner surface of the connecting plate 7022 towards the frame body 200, because there is a gap between the part of the optical touch component 301 protruding from the frame body 200 and the connecting plate 2012, the water droplets on the inner surface of the connecting plate 2021 will not come into contact with the optical touch component 301, and will not spread to the optical touch component 301. This ensures that the water droplets all flow to the end face of the frame body 200 facing the connecting plate 7022, and then flow through the end face of the frame body 200 into the water channel H.

[0105] It should be noted that, please refer to Figure 15 , Figure 15 This is a schematic diagram of another display device provided in this application embodiment. The portion of the first optical touch frame 701 used to connect to the frame body 200 may have a second sliding groove K4. The second sliding groove K4 may communicate with the first strip groove K1 for the assembly and disassembly of the optical touch component 301. Simultaneously, the second sliding groove K4 may also communicate with the water channel H, and the second sliding groove K4 may penetrate the first optical touch frame 701 in the second direction Y. Thus, water flowing into the water channel H can flow into the second sliding groove K4 under gravity, and then flow through the second sliding groove K4 to the outside of the first optical touch frame 701, thereby flowing outside the display device.

[0106] Optional, please refer to Figure 16 , Figure 16This is a partial exploded view of another display device provided in an embodiment of this application. The first corner block 400 in the frame 200 may include: a corner block 401 located on the connecting plate 2021 in the second frame 202, and a first adapter portion 402 and a second adapter portion 403 fixedly connected to the corner block 401. The first adapter portion 402 in the first corner block 400 can extend into the interior of the frame body 200 in the third optical touch frame 703 to be fixedly connected to the frame body 200, and the second adapter portion 403 in the first corner block 400 can extend into the interior of the main frame portion 7021 in the second optical touch frame 702 to be fixedly connected to the main frame portion 7021. A first gap P1 may exist between the corner block 401 in the first corner block 400 and the frame body 200, and a second gap P2 may exist between the corner block 401 and the connecting plate 7022.

[0107] It should be noted that the frame body 200 in the third optical touch frame and the first optical touch frame 701 can be connected by a second corner block. The structure of the second corner block can be the same as that of the first corner block 400, which will not be described in detail here.
