Description

Technical Field

[0001] The present disclosure relates to the field of display technology, and in particular to an optical touch frame and a display device. Background Art

[0002] Optical touch devices use infrared transmitters and receivers on opposite sides of a display screen. The infrared light emitted by the transmitter is blocked, preventing the receiver from responding, thus enabling the touch position to be determined. Currently, optical touch is achieved by refracting the infrared light emitted by the transmitter through a filter strip, making the emitted light parallel to the display screen.

[0077] To make the above-mentioned purposes, features, and advantages of the present disclosure more clearly understood, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative work are within the scope of protection of the present disclosure.

[0078] In the related art, refer to Figure 1 , Figure 1 The structure diagram of the infrared touch device in the related art is shown in FIG. Figure 1 As shown, in the infrared touch device, a profile frame 2' is wrapped around the four sides of the display screen, and an infrared transmitter and an infrared receiver are set in the cavity of the profile frame 2'. The infrared receiver on this side receives the infrared light emitted by the infrared transmitter on the opposite side. When a touch operation occurs, the infrared light passing through the touched area will be blocked and cannot be received by the infrared receiver. The touched area can be located according to the infrared receiver, thereby achieving corresponding control operations based on the touched area.

[0079] Among them, a filter strip 1' is provided at the opening position of the profile outer frame 2' toward the display screen. The filter strip 1' can block visible light and transmit infrared light to prevent visible light from affecting infrared touch. However, Figure 1 As shown, the filter strip 1 ′ is located at the side of the display screen, so that part of the infrared light emitted by the infrared lamp is refracted by the filter strip 1 ′ and blocked, making the touch height of the optical touch device higher.

[0080] At the same time, since there is inevitably a designed gap between the filter strip 1′ and the display screen cover of the infrared touch device, external water flow can enter the profile frame 2′ along the designed gap, and then enter the position where the infrared touch component is located in the profile frame 2′, damaging the infrared transmitter, infrared receiver and other components that realize infrared touch, thereby shortening the service life of the infrared touch screen.

[0081] In addition, since the connection between the filter strip 1 ′ and the profile frame 2 ′ is simply fixed to the profile frame 2 ′, when the infrared touch device falls, the filter strip 1 ′ can easily fall out of the profile frame 2 ′, damaging the infrared touch device.

[0082] In view of this, the present disclosure provides an optical touch frame and an optical touch device, which provide a first installation cavity on the profile frame, and provide a first plug-in portion in conjunction with the filter strip, and embed the first plug-in portion in the first installation cavity to realize the plug-in of the filter strip and the profile frame. At the same time, since the first opening of the first installation cavity is consistent with the opening direction of the second opening of the accommodating space of the profile frame, the first opening of the first installation cavity faces the side where the transparent cover plate is located. Therefore, when external water flows from the transparent cover plate into the profile frame, it is received by the first installation cavity and will not flow into the accommodating space of the profile frame, thereby improving the waterproof performance of the optical touch frame.

[0083] Reference Figure 2 and Figure 3 , Figure 2 FIG2 shows a schematic diagram of the structure of the optical touch frame provided by an embodiment of the present disclosure. Figure 3 Shown Figure 2 The structural diagram of the profile outer frame 2 of the optical touch frame is as follows: Figure 2 and Figure 3 As shown, the optical touch frame specifically includes:

[0084] The profile outer frame 2 has an accommodating space 3 for accommodating the optical touch component 4 and a first installation cavity 211. A first opening 211a is provided on one side of the first installation cavity 211;

[0085] The filter strip 1 includes a first plug-in portion 12 , which is embedded in the first mounting cavity 211 ;

[0086] The accommodating space 3 has a second opening 31 , and the second opening 31 is used for emitting or receiving a touch light signal. The opening direction of the first opening 211 a is the same as the opening direction of the second opening 31 .

[0087] The accommodating space 3 can be a space opened in the profile frame 2 to accommodate the optical touch component 4. The optical touch component 4 can be an infrared touch component or other optical component capable of achieving touch. The accommodating space 3 at least includes a mounting space for the light-emitting device of the optical touch component 4. The second opening 31 of the accommodating space emits or receives a touch light signal. The filter strip can cover the second opening to filter part of the light to prevent it from affecting the optical touch component. For example, in the case where the optical touch component 4 is an infrared touch component, the filter strip 1 is a filter strip 1 that shields external visible light and transmits infrared light. By covering the filter strip 1 with the second opening 31, the optical touch component 4 receives infrared light without being interfered with by other visible light, so that the optical touch device can achieve touch based on infrared light.

[0088] In some examples, the accommodating space 3 may be located in the area enclosed by the profile frame 2 and the filter strip 1, for example. Figure 2 As shown, the optical touch component 4 is located in the gap between the profile frame 2 and the filter strip 1 , wherein the light emitted by the optical touch component 4 can be radiated to the filter strip 1 , and then the filter strip 1 refracts the light to be parallel to the display screen of the optical touch device.

[0089] The opening direction of the second opening 31 determines the light emitting position of the optical touch component 4. Since the filter strip 1 can refract the light emitted by the optical touch component 4, when the filter strip 1 covers the second opening 31, the filter strip 1 can refract the light to be parallel to the transparent cover of the display screen in the optical touch device, that is, Figure 3 The direction indicated by the y-axis in the middle portion allows the optical touch assembly 4 to emit light signals to the opposite side or receive light signals emitted from the opposite side, thereby avoiding being affected by the transparent cover. It is understood that the second opening 31 and the projection of the transparent cover on the outer frame of the profile do not overlap to avoid the situation where some light is unable to be emitted to the opposite side.

[0090] In this embodiment, the opening direction of the first opening 211a may refer to the side to which the first mounting cavity 211 opens, which needs to be treated differently from the diameter direction of the first opening 211a. Similarly, the opening direction of the second opening 31 refers to the side to which the accommodating space 3 opens, and its opening direction is orthogonal to the diameter direction. Specifically, Figure 3 As shown, the first mounting cavity 211 is open in the y direction, and the opening direction of the first opening 211a can be referred to as Figure 3 The y direction in the figure, the diameter of the first opening 211a refers to the x direction, and the opening direction of the second opening 31 can also be Figure 3 The direction indicated by the y-axis.

[0091] Among them, the first installation cavity 211 can be located close to the optical touch component 4 and close to the display screen of the optical touch device. In this way, when the opening direction of the first opening 211a of the first installation cavity 211 is the same as the opening direction of the second opening 31, the first plug-in portion 12 is close to the position of the optical touch component 4 and covers part of the profile frame 2. Then, when the first plug-in portion 12 is plugged into the first installation cavity 211, a partial area of ​​the first plug-in portion 12 can also refract the light signal so that its exit direction is parallel to the display screen, thereby reducing the touch height of the optical touch device.

[0092] The opening direction of the first opening 211a is the same as the opening direction of the second opening 31. The opening directions of the two may be exactly the same or substantially the same. In the case where the opening direction of the first opening 211a is exactly the same as the opening direction of the second opening 31, the opening direction of the second opening 31 is Figure 3 The direction indicated by the y-axis is the direction indicated by the y-axis, and the opening direction of the first opening 211a is also Figure 3 The direction indicated by the y-axis, at this time, Figure 2 As shown, the first plug-in portion 12 can be connected to the first mounting cavity 211 on the side of the transparent cover plate, thereby enabling the light signal emitted from the second opening 31 to be refracted on the side of the transparent cover plate, thereby reducing the touch height of the optical touch device; when the opening direction of the first opening 211a is substantially the same as the opening direction of the second opening 31, the opening direction of the first opening 211a can be parallel to the opening direction of the second opening 31, and the parallelism can mean that the angle between them is 0° to 5°. Within this range, the filter strip 1 can also enable the light signal emitted from the second opening 31 to be refracted on the side of the transparent cover plate, thereby reducing the touch height of the optical touch device.

[0093] The filter bar 1 includes a first plug-in portion 12 , through which the filter bar 1 can be fixed in the first mounting cavity 211 of the profile frame 2 of the optical touch device.

[0094] In one embodiment, the profile frame 2 may be provided with a plurality of mounting cavities, and the plurality of mounting cavities may be located at different positions of the profile frame 2. The filter strip 1 may then include a plurality of plug-in portions corresponding to the plurality of mounting cavities, respectively. The plurality of plug-in portions are respectively embedded in the plurality of mounting cavities, thereby improving the stability of the connection between the filter strip 1 and the profile frame 2.

[0095] In this embodiment, the shape of the first plug-in portion 12 can be irregular or regular, specifically, it can include an inverted T-shape, an L-shape, an irregular spherical shape, etc. Figure 2 For example, the cross section of the first plug-in portion 12 on the plane formed by the x-axis and the y-axis can be approximately L-shaped, or

[0096] It can be approximately in an inverted T shape, or can be similar to the shape of a light bulb.

[0097] For example, when the orthographic projection of the first plug-in portion 12 on the plane formed by the x-axis and the y-axis is approximately L-shaped, the orthographic projection of the first mounting cavity 211 in the profile outer frame 2 on the plane formed by the x-axis and the y-axis can be an L-shape that matches the first plug-in portion 12. Similarly, when the orthographic projection of the first plug-in portion 12 on the plane formed by the x-axis and the y-axis is approximately inverted T-shaped, the orthographic projection of the first mounting cavity 211 in the profile outer frame 2 on the plane formed by the x-axis and the y-axis can be a shape that matches the first plug-in portion 11. When the orthographic projection of the first plug-in portion 12 on the plane formed by the x-axis and the y-axis is approximately spherical, the orthographic projection of the first mounting cavity 211 in the profile outer frame 2 on the plane formed by the x-axis and the y-axis can be a spherical shape that matches the first plug-in portion 12. When this design is adopted, the first plug-in portion 12 is not easily dislodged from the first mounting cavity 211.

[0098] In one embodiment, since the filter strip 1 is made of plastic and is hydrophobic, the filter strip 1 can be partially extended to absorb moisture that may enter the profile frame 2, thereby providing waterproof performance for the optical touch device.

[0099] The optical touch frame provided by the embodiment of the present disclosure is adopted, by providing a first installation cavity 211 in the profile outer frame 2, and making the opening direction of the first opening 211a of the first installation cavity 211 parallel to the opening direction of the second opening 31 of the accommodating space 3 for accommodating the optical touch component 4 in the profile outer frame 2. In this way, when external water flows into the profile outer frame along the transparent cover of the optical touch device, it is received by the first installation cavity 211, thereby preventing the water flow from directly entering the accommodating space 3 of the profile outer frame, causing damage to the optical touch component 3 in the accommodating space 3. In addition, when the first plug-in portion 12 of the filter strip 1 is embedded in the first installation cavity 211, the first plug-in portion 12 of the filter strip 1 is close to the optical touch component 4 and the side of the transparent cover in the optical touch device, thereby reducing the touch height of the optical touch device.

[0100] It is understandable that continuing to refer to Figure 2 , the filter bar 1 blocks the second opening 31, so that the light signal emitted by the optical touch component located in the accommodating space 3 can be refracted by the filter bar 1 when it exits the second opening 31, thereby enabling it to exit parallel to the transparent cover, thereby propagating the emitted light signal to the opposite side. Similarly, the light signal on the opposite side can be refracted by the filter bar 1, and then propagated through the second opening 31 to the optical touch component 4 for reception. In this way, when a touch event occurs, the position where the touch operation occurs can be determined based on the unreceived light signal.

[0101] In one embodiment, considering that there is a designed gap between the transparent cover and the filter strip 1 in the optical touch device, water can flow into the optical touch frame from the designed gap, and the filter strip 1 is usually made of plastic and has poor hydrophilicity. Therefore, the filter strip 1 can be used to guide the flow of water, so that the water entering from the gap can be guided to the outside, thereby improving the service life of the optical touch device. Therefore, continue to refer to Figure 2 and Figure 3 , the first installation cavity 211 includes:

[0102] first wall 211b;

[0103] The second wall 211 c is located on a side of the first wall 211 b away from the second opening 31 and forms a first gap 231 with the first plug-in portion 12 ;

[0104] The filter strip 1 includes a water-blocking strip 13 , which blocks the first gap 231 .

[0105] In this embodiment, the first wall 211b and the second wall 211c are two opposite walls of the first installation cavity 211. When the first installation cavity 211 is connected to the first plug-in portion 12, there are gaps between the two walls of the first installation cavity 211 and the first plug-in portion 12. Water may flow into the first installation cavity 211 and then enter the accommodating space 3 along the first gap 231 between the second wall 211c and the first plug-in portion 12, causing damage to the optical touch component 4. Therefore, the water retaining bar 13 of the filter bar 1 is used to block the first gap 231. When external water flows through the gap between the filter bar 1 and the display screen and enters the profile frame 2, the water retaining bar 13 can prevent the water from flowing along the first installation cavity 211 into the accommodating space 3 where the optical touch component 4 is located, thereby preventing the problem of water entering and damaging the optical touch component 4, thereby affecting the life of the device.

[0106] In some examples, the water retaining bar 13 extends from the position of the filter bar 1 toward the first opening 211a to block the first gap 231. The water retaining bar 13 can simultaneously block the second gap between the first wall 211b and the first plug-in portion 12. Specifically, the side structure of the filter bar 1 near the second opening 31 can block the second gap, and the side structure of the filter bar 1 near the second opening 31 can be in close contact with the surface of the profile outer frame 2. In this way, the filter bar 1 seals and blocks the second gap, so that the outlet of the second gap is blocked and water cannot overflow, thereby preventing water from flowing toward the optical touch component. In other examples, the first plug-in portion 12 can be in close contact with the bottom wall of the first mounting cavity 211, so that the second gap can become a sealed gap, preventing water from flowing from the first gap 231 into the second gap.

[0107] In some examples, the water retaining bar 13 may be in close contact with the profile frame 2 at the position of the first installation cavity 211, or a gap may exist between the water retaining bar 13 and the profile frame 2 at the position of the first installation cavity 211, so that water flows into the first installation cavity 211 through the gap.

[0108] The water barrier 13 can be formed by extending part of the first plug-in portion 12 to facilitate shielding

[0109] The first gap 231 formed by the first plug-in portion 12 and the second wall 211c, the orthographic projection of the water retaining bar 13 on the plane formed by the x-axis and the y-axis and the opening direction of the second opening 31, or the opening direction of the second opening 31 are at a certain angle. This angle is not specifically limited in this embodiment, and it is sufficient to block the water flow.

[0110] In the case where the orthographic projection of the plane formed by the water retaining bar 13 on the x-axis and the y-axis is orthogonal to the opening direction of the second opening 31, as shown in FIG. Figure 2 As shown, when the water flows from one side of the filter strip 1 to the water retaining strip 13, the water retaining strip 13 blocks the water flow so that it does not flow into the location of the optical touch component 4. When the water flow accumulates more, the water retaining strip 13 can also guide the water flow to the surface of the profile frame 2, and then flow out of the profile frame 2.

[0111] When the orthographic projection of the water retaining bar 13 on the plane formed by the x-axis and the y-axis forms a certain angle with the opening direction of the second opening 31, continue to refer to Figure 2 The side of the water retaining bar 13 away from the second opening 31 includes a slope inclined in the direction of the first opening 211a. When the water flows from one side of the filter strip 1 to the water retaining bar 13, it can be directly guided by the water retaining bar 13 to the surface of the profile outer frame 2, and then flow out of the profile outer frame 2 along the surface of the profile outer frame 2, thereby accelerating the speed of water flowing out of the profile outer frame 2 and improving the waterproof performance of the optical touch frame.

[0112] In one understanding, continue to refer to Figure 2 The water retaining bar 13 includes a connecting end connected to the filter bar 1 and a free end not connected to the filter bar 1. The free end has a slope, which is a slope inclined toward the direction of the first opening 211a. In this way, when water flows accumulate at the position where the water retaining bar 13 is located, the water flow can be guided by the slope to flow toward the surface of the profile frame 2, thereby preventing the water flow from entering the first gap 231.

[0113] In another understanding, the slope of the water retaining strip 13 can be represented by the angle between the water retaining strip 13 and the first opening 211a, referring to Figure 4 , Figure 4 The structural diagram of the water retaining bar 13 in the embodiment of the present disclosure is shown as follows. Figure 4As shown, assuming that the caliber direction of the first opening 211a is L, there is an angle between the side of the water retaining bar 13 facing away from the first opening 211a, that is, the side of the water retaining bar 13 facing away from the first gap 231 and the caliber direction L, and the angle can be greater than 0 degrees and less than 90 degrees. At the same time, the water retaining bar 13 takes the caliber direction L as the horizontal line, and the slope of the slope of the water retaining bar 13 relative to the horizontal line is less than 0, which makes the slope inclined toward the direction of the first gap 231.

[0114] Of course, in some embodiments, the side of the water retaining bar 13 close to the first gap 231 is aligned with the diameter side.

[0115] The directions L may be parallel to each other, so that the water retaining strip 13 can conveniently cover the first gap 231 and the second gap between the first plug-in portion 12 and the first wall 211b.

[0116] Among them, there is a gap between the water retaining bar 13 and the side of the profile outer frame 2 close to the water retaining bar 13, that is, the water retaining bar 13 does not seal the first gap 231. At this time, part of the water flow can flow into the first installation cavity 211 along the gap between the water retaining bar 13 and the side of the profile outer frame 2 close to the water retaining bar 13, and then part of the water can accumulate in the first installation cavity 211.

[0117] In this case, a second gap is provided between the first wall 211b and the first plug-in portion 12, and the filter strip 1 seals and blocks the second gap. By blocking the second gap between the first wall 211b and the first plug-in portion 12 with the filter strip 1, moisture flowing into the first mounting cavity 211 can be prevented from entering the accommodating space 3 along the second gap between the first wall 211b and the first plug-in portion 12 and damaging the optical touch assembly 4.

[0118] In one embodiment, continue to refer to Figure 2 and Figure 3 , the profile frame 2 also includes:

[0119] The water storage tank 212 is communicated with the first installation cavity 211 .

[0120] Specifically, the water storage tank 212 is connected to the first installation cavity 211. When part of the water flows into the first installation cavity 211 along the first gap 231, the water entering the first installation cavity 212 can be stored in the water storage tank 212, thereby avoiding the situation where the space in the first installation cavity 211 is small, causing water to flow into the accommodating space 3 along the second gap and damage the optical touch component 4 therein.

[0121] Of course, the water storage tank 212 can also be used in conjunction with the water retaining bar 13 in the filter strip 1. The water retaining bar 13 blocks most of the water from entering the first installation cavity 211, while a small part of the water that cannot be blocked enters the first installation cavity 211 and flows into the water storage tank 212, thereby achieving waterproofing from two aspects and improving the waterproof performance of the optical touch frame.

[0122] Among them, since the water tank 212 is connected to the first installation cavity 211, and there are gaps between the first wall 211b, the second wall 211c and the first plug-in portion 12 of the first installation cavity 211, the water accumulated in the water tank 212 can leave the water tank 212 due to evaporation, thereby avoiding the problem of continuous accumulation of water in the water tank 212 causing excessive water to enter the accommodating space 3 of the profile outer frame 2.

[0123] In one embodiment, the water storage tank 212 is located on a side of the first installation cavity 211 away from the first opening 211 a ; and / or, the water storage tank 212 is located on a side of the first installation cavity 211 away from the second opening 31 .

[0124] In this embodiment, the water storage tank 212 can be located on the side of the first installation cavity 211 away from the first opening 211a, or on the side of the first installation cavity 211 away from the second opening 31, or on the side of the first installation cavity 211 away from the second opening 31.

[0125] The first installation cavity 211 is away from the first opening 211a and away from one side of the second opening 31. In this way, the accumulated water in the water storage tank 212 can be kept away from the location of the optical touch component 4, preventing it from entering the accommodating space 3 of the profile frame 2 and damaging the optical touch component 4.

[0126] In the case where the water storage tank 212 is located on the side of the first installation cavity 211 away from the first opening 211a, the water storage tank 2112 can be located at the bottom of the first installation cavity 211 and extend away from the first opening 211a. In this way, the water flow entering along the first gap 231 can directly flow along the second wall 211c into the bottom of the first installation cavity 211 and then flow into the water storage tank 212, so that the water is stored in the water storage tank 212. In the case where the water storage tank 212 is located in the first installation cavity 211 away from the second opening 31, the water storage tank 212 is connected to the wall surface of the second wall 211c and extends along the first gap 231. Figure 2 In this way, the water flowing into the first slit 231 can flow into the water storage tank 212 along the wall surface of the second wall 211c and accumulate in the water storage tank 212. When the water storage tank 212 is located on the side of the first installation cavity 211 away from the first opening 211a and away from the second opening 31, as shown in FIG. Figure 2As shown, the water reservoir 212 extends away from the second opening 31 and is inclined away from the first opening 211a. When water enters the first mounting cavity 211, it flows along the wall of the first mounting cavity 211 to the bottom of the first mounting cavity 211 and gradually enters the water reservoir 212 along the inclined surface, thereby allowing the water reservoir 212 to store water. Therefore, when the water reservoir 212 extends away from the second opening 31, water flowing into the first mounting cavity 211 is accumulated on the side away from the optical touch assembly 4, thereby reducing the risk of water from the water reservoir 212 overflowing and corroding the optical touch assembly 4.

[0127] The cross-sectional area of ​​the water storage tank 212 is 2 to 3 square millimeters. Under this cross-sectional area, the water storage tank 212 can fully meet the water storage requirements. The cross-sectional area may include: a first cross-sectional area of ​​the water storage tank 212 in the diameter direction of the first opening 211a of the first installation cavity 211, and a second cross-sectional area of ​​the water storage tank 212 in the opening direction of the first opening 211a of the first installation cavity 211. The first area is 2 to 3 square millimeters, and the second area can be 2 to 3 square millimeters. The first area can be larger than the second area.

[0128] For example, the cross-sectional area of ​​the water storage tank 212 can be as follows: Figure 2 The area of ​​the orthographic projection of the water storage tank 212 on the plane formed by the x-axis and the y-axis is shown.

[0129] For example, the cross-sectional area of ​​the water storage tank 212 can be 2 square millimeters, 2.3 square millimeters, 2.5 square millimeters, 2.8 square millimeters, or 3 square millimeters.

[0130] In one embodiment, the material of the cavity wall of the first installation cavity 211 can also be improved so that the first installation cavity 211 has water absorption ability, further improving the waterproof performance of the optical touch frame. Specifically, part or all of the cavity wall of the first installation cavity 211 can be coated with a water absorption film.

[0131] In this embodiment, a water-absorbing film is applied to part or all of the cavity walls of the first installation cavity 211 so that the moisture entering along the first gap 231 can be fully or partially absorbed by the cavity walls of the first installation cavity 211. Waterproofing can be achieved simultaneously through the water-absorbing film and the water storage tank 212, thereby avoiding excessive accumulation of moisture in the water storage tank 212, causing part of the water to overflow from the first installation cavity 211 and enter the accommodating space 3 of the profile outer frame 2, thereby further improving the waterproof performance of the optical touch frame.

[0132] In some examples, the water-absorbing film may be a sponge material, an activated carbon material, or the like having water-absorbing properties.

[0133] In one embodiment, referring to Figure 3The size of at least part of the inner space of the first installation cavity 211 in the target direction is larger than the size of the first opening 211a in the target direction; wherein the target direction is orthogonal to the opening direction of the first opening 211a. Figure 3 For example, the target direction is the direction of the x-axis.

[0134] In this embodiment, the size of at least part of the internal space of the first mounting cavity 211 in the target direction is larger than the size of the first opening 211a in the target direction. In this way, the first opening 211a of the first mounting cavity 211 is similar to the design of a small wellhead, and the first plug-in portion 12 is adapted to the shape of the first mounting cavity 211. In this way, when the first plug-in portion 12 is plugged into the first mounting cavity 211, the first plug-in portion 12 will be restricted in the first mounting cavity 211, preventing the first plug-in portion 12 from detaching from the first mounting cavity 211 when subjected to external impact, thereby improving the anti-escape performance of the optical touch frame.

[0135] Specifically, Figure 2 For example, when the first plug-in portion 12 of the filter strip 1 is inserted into the first mounting cavity 211, since the size of the space in the first mounting cavity 211 in the x-axis direction is larger than the size of the first opening 211a in the x-axis direction, the first plug-in portion 12 is confined within the first mounting cavity 211 and is difficult to escape from the first opening 211a. In this way, when the optical touch device is subjected to external impact, the first mounting cavity 211 can provide support for the filter strip 1, thereby preventing it from jumping off the profile frame 2.

[0136] In one embodiment, Figure 3 For example, the size of the first installation cavity 211 in the direction indicated by the x-axis may gradually increase and then gradually decrease along the y-axis.

[0137] The size of the first installation cavity 211 in the direction indicated by the x-axis can gradually increase and then gradually decrease along the y-axis direction.

[0138] The size in the direction increases linearly and then decreases linearly, or the size of the first installation cavity 211 in the x-axis direction increases linearly and then decreases nonlinearly along the direction indicated by the y-axis, or the size of the first installation cavity 211 in the x-axis direction increases nonlinearly and then decreases linearly along the direction indicated by the y-axis, or the size of the first installation cavity 211 in the x-axis direction increases nonlinearly and then decreases nonlinearly along the direction indicated by the y-axis.

[0139] Specifically, when the size of the first installation cavity 211 in the x-axis direction linearly increases and decreases along the direction indicated by the y-axis, the cross-section of the first installation cavity 211 can be rhombus-shaped, specifically, a regular rhombus or an irregular rhombus.

[0140] Specifically, along the direction indicated by the y-axis, the size of the first mounting cavity 211 in the x-axis direction increases linearly and decreases nonlinearly, then the side wall surface of the first mounting cavity 211 can be composed of a linear inclined surface and a circular arc surface, and the inclined surface is close to the first opening 211a, and the circular arc surface is close to the bottom of the first mounting cavity 211, or, along the direction indicated by the y-axis, the size of the first mounting cavity 211 in the x-axis direction increases nonlinearly and decreases linearly, then the inclined surface is close to the bottom of the first mounting cavity 211, and the circular arc surface is close to the first opening 211a.

[0141] Specifically, along the direction indicated by the y-axis, the size of the first installation cavity 211 in the x-axis direction increases and decreases nonlinearly, and the sidewall of the first installation cavity 211 may be composed of an arc surface.

[0142] Of course, the first mounting cavity 211 includes multiple walls in the direction indicated by the y-axis, and the shapes of each wall can be the same or different. For example, it can include two walls, one of which is an inclined surface and the other is an arc surface; or both walls can be arc surfaces.

[0143] It is understandable that the cross-sectional shape of the inner chamber of the first installation cavity 211 can be a symmetrical figure or an asymmetrical figure, as long as the size of at least part of its area in the target direction X is greater than the size of the first opening in the target direction X. In summary, the cross-sectional shape of the inner chamber of the first installation cavity 211 can be a circular segment shape, and the first opening 211a is located at the notch of the circular segment; or Figure 3 As shown, the cross section of the inner chamber of the first installation cavity 211 may be approximately L-shaped, and part of the side wall has an arc surface, so that the first installation cavity 211 has an irregular shape, thereby enhancing the anti-escape performance.

[0144] In combination with the above embodiments, the filter strip 1 can be connected to the profile frame 2 through multiple plug-in parts. In some embodiments, two mounting cavities can be used to fix the filter strip 1, thereby facilitating the stability of the filter strip 1 on the profile frame 2. Specifically, a plurality of mounting cavities can be added on the basis of the first mounting cavity 211.

[0145] The second mounting cavity 221 is used to fix the filter strip 1. Specifically, continue to refer to Figure 2 and Figure 3 , the profile frame 2 also includes:

[0146] The second mounting cavity 221, the first mounting cavity 211 and the second mounting cavity 221 are respectively located on opposite sides of the second opening 31; wherein the second mounting cavity 221 has a third opening 221a, and the opening direction of the third opening 221a intersects with the opening direction of the first opening 211a;

[0147] The filter strip 1 further includes:

[0148] The second plug-in portion 14 is embedded in the second installation cavity 221 .

[0149] In this embodiment, the second mounting cavity 221 and the first mounting cavity 211 can be located on opposite sides of the second opening 31, respectively. In this way, the filter strip 1 can be located in the second opening 31, which facilitates the refraction of light through the filter strip 1 and avoids interference of different light on the optical touch component 4.

[0150] When the filter strip 1 is fixed using the first mounting cavity 211 and the second mounting cavity 221, the filter strip 1 further includes a second plug-in portion 14, which is embedded in the second mounting cavity 221. In this case, if the filter strip 1 is subjected to an impact force, the first plug-in portion 12 in the first mounting cavity 211 is supported by the wall of the first mounting cavity 211, and the second plug-in portion 14 in the second mounting cavity 221 is supported by the wall of the second mounting cavity 221, thereby providing a buffering effect and further preventing the filter strip 1 from falling off.

[0151] In this embodiment, the opening direction of the third opening 221a intersects with the direction of the first opening 211a, so that the opening direction of the first opening 211a is inconsistent with the opening direction of the third opening 221a. As a result, the filter strip 1 is connected to the profile frame 2 from different directions, thereby enhancing the connection stability between the filter strip 1 and the profile frame 2. The angle at which the opening direction of the third opening 221a intersects with the opening direction of the first opening 211a can be between 30° and 150°, such as the angle between the opening direction of the third opening 221a and the opening direction of the first opening 211a is 30°, 60°, 90°, 120°, or 150°. It should be noted that the opening direction of the third opening 221a is not limited to the following. Figure 2 The direction toward the x-axis shown in may deviate from the x-axis direction, such as an angle of 10° or 20° to the x-axis.

[0152] In some examples, the first mounting cavity 211 and / or the second mounting cavity 221 may have a spherical shape.

[0153] Specifically, the first installation cavity 211 may be spherical, the second installation cavity 221 may be spherical, or both the first installation cavity 211 and the second installation cavity 221 may be spherical.

[0154] In the case where the first mounting cavity 211 is spherical, the shape of the first plug-in portion 12 matches the shape of the first mounting cavity 211. The spherical cavity can increase the contact area between the first plug-in portion 12 and the cavity wall of the first mounting cavity 211. In this way, when the filter strip 1 is subjected to an impact force, the impact force on the first plug-in portion 12 can be reduced. In addition, the arc surface of the cavity wall can act as a buffer, allowing the filter strip 1 to withstand a large impact force without falling out, thereby improving the anti-fallout performance of the filter strip 1.

[0155] In the case where the second mounting cavity 221 is spherical, the shape of the second plug-in portion 14 is adapted to the shape of the second mounting cavity 221, and the cavity wall of the second mounting cavity 221 is an arc surface. In this way, if the filter strip 1 is impacted, the arc surface can provide a buffering effect for the second plug-in portion 14, thereby preventing the filter strip 1 from being damaged due to the impact.

[0156] When the first mounting cavity 211 and the second mounting cavity 221 are both spherical, a buffering effect can be provided for the filter strip 1 in two directions, further reducing the impact on the filter strip 1 and preventing the filter strip 1 from falling out of the profile frame 2 or being damaged.

[0157] In one embodiment, continue to refer to Figure 2 and Figure 3 The first plug-in portion 12 has at least one first area, the size of which in the first target direction is larger than the size of the first opening 211a in the first target direction; and / or the second plug-in portion 14 has at least one second area, the size of which in the second target direction is larger than the size of the third opening 221a in the second target direction.

[0158] The first target direction is perpendicular to the opening direction of the first opening 211 a , and the second target direction is perpendicular to the opening direction of the third opening 221 a .

[0159] In this embodiment, Figure 2 For example, the first target direction is Figure 2 The direction indicated by the x-axis, the second target direction is Figure 2 The direction indicated by the y-axis.

[0160] The first region may be the region of the first plug-in portion 12 with the largest dimension in the x-axis direction, and the second region may be the region of the second plug-in portion 14 with the largest dimension in the x-axis direction. For example, if the first plug-in portion 12 is spherical, the first region is the location of the sphere with the largest diameter in the x-axis direction; if the first plug-in portion 12 is triangular, the first region is the location of the triangle close to the base; if the first plug-in portion 12 is L-shaped, the first region is the location of one side of the L-shape parallel to the x-axis; similarly, if the second plug-in portion 14 is spherical, the second region is the location of the sphere with the largest diameter in the y-axis direction; if the second plug-in portion 14 is triangular, the second region is the location of the triangle close to the base. Of course, the first region may be one or more; the second region may be one or more; if the first region is stepped, the platform region of the multiple steps may be larger than the dimension of the first opening 211a in the x-axis direction.

[0161] Among them, the size of the first area of ​​the first plug-in portion 12 in the x-axis direction may be larger than the size of the first opening 211a in the x-axis direction; the size of the second area of ​​the second plug-in portion 14 in the y-axis direction may be larger than the size of the third opening 221a in the y-axis direction; the size of the first area of ​​the first plug-in portion 12 in the x-axis direction may be larger than the size of the first opening 211a in the x-axis direction, and the size of the second area of ​​the second plug-in portion 14 in the y-axis direction may be larger than the size of the third opening 221a in the y-axis direction.

[0162] Specifically, when the size of the first area of ​​the first plug-in portion 12 in the x-axis direction is larger than the size of the first opening 211a in the x-axis direction, the larger side of the first plug-in portion 12 can be confined in the first mounting cavity 211, preventing the first plug-in portion 12 from escaping from the first mounting cavity 211 and causing the filter strip 1 to escaping from the optical touch frame; similarly, when the size of the second area of ​​the second plug-in portion 14 in the y-axis direction is larger than the size of the third opening 221a in the y-axis direction, the larger side of the second plug-in portion 14 can be confined in the second mounting cavity 221, preventing Because the second plug-in portion 14 escapes from the second mounting cavity 221, the filter strip 1 escapes from the optical touch frame. In the case where the size of the first area of ​​the first plug-in portion 12 in the x-axis direction is larger than the size of the first opening 211a in the x-axis direction, and the size of the second area of ​​the second plug-in portion 14 in the y-axis direction is larger than the size of the third opening 221a in the y-axis direction, the first plug-in portion 12 is confined within the first mounting cavity 211, and the second plug-in portion 14 is confined within the second mounting cavity 221. In this way, the filter strip 1 is unlikely to escape from the profile frame 2, further improving the stability of the filter strip 1.

[0163] It is understandable that the shape of the mounting cavity in the profile outer frame 2 is adapted to the shape of the plug-in portion of the filter strip 1, which can save space, reduce material waste, and ensure the stability of the filter strip 1. Figure 2 and Figure 3 For example, the shape of the orthographic projection of the first mounting cavity 211 on the plane formed by the x-axis and the y-axis is consistent with the shape of the orthographic projection of the first plug-in portion 11 on the plane formed by the x-axis and the y-axis, and the shape of the orthographic projection of the second mounting cavity 221 on the plane formed by the x-axis and the y-axis is consistent with the shape of the orthographic projection of the second plug-in portion 14 on the plane formed by the x-axis and the y-axis.

[0164] For example, the orthographic projection of the first plug-in portion 12 on the plane formed by the x-axis and the y-axis is approximately

[0165] When the orthographic projection of the first mounting cavity 211 on the plane formed by the x-axis and the y-axis is approximately L-shaped, when the orthographic projection of the first plug-in portion 12 on the plane formed by the x-axis and the y-axis is approximately an inverted T-shape, the orthographic projection of the first mounting cavity 211 on the plane formed by the x-axis and the y-axis is also approximately an inverted T-shape; when the orthographic projection of the first plug-in portion 12 on the plane formed by the x-axis and the y-axis is approximately circular, the orthographic projection of the first mounting cavity 211 on the plane formed by the x-axis and the y-axis is approximately circular. The shape of the projection is also approximately circular, so that the first plug-in portion 12 can be fully adapted to the first mounting cavity 211. When the filter strip 1 is subjected to force due to the tilting of the transparent cover in the optical touch device, the first mounting cavity 211 can restrict the first plug-in portion 12 to prevent it from jumping out of the first mounting cavity 211, thereby improving the anti-jumping performance of the optical touch frame. Similarly, the orthographic projection of the second plug-in portion 14 on the plane formed by the x-axis and the y-axis is the same as the orthographic projection shape of the second mounting cavity 221 on the plane formed by the x-axis and the y-axis.

[0166] In one embodiment, referring to Figure 2 and Figure 5 ,in, Figure 5 FIG. 1 shows a schematic structural diagram of the filter strip 1 in this embodiment. Figure 5 As shown, the filter strip 1 includes:

[0167] The filter strip body 11 includes a first surface 111, a second surface 112, and a third surface 113. The first surface 111 and the second surface 112 are adjacent to each other, and the third surface 113 is opposite to the first surface 111 and adjacent to the second surface 112.

[0168] A connecting portion 15, through which the first plug-in portion 12 is connected to the filter strip body 11;

[0169] Among them, the connecting part 15 is connected to the second surface 112, and the second plug-in part 14 is connected to the first surface 111; or, the connecting part 15 is connected to the third surface 113, and the second plug-in part 14 is connected to the first surface 111; or, the connecting part 15 is connected to the connection between the second surface 112 and the third surface 113, and the second plug-in part 14 is connected to the first surface 111.

[0170] In this embodiment, the connecting portion 15 can be located at different positions of the filter bar 1 as long as it can connect the first plug-in portion 12 with the filter bar body 11 .

[0171] For example, refer to Figure 6 , Figure 6 FIG. 1 shows a structural diagram of a filter strip 1 provided in another embodiment of the present disclosure. Figure 6 As shown, the connecting portion 15 is connected to the second surface 112 of the filter strip body 11, and the second plug-in portion 12 is connected to the first surface 111. At this time, the extending direction of the connecting portion 15 is orthogonal to the opening direction of the first opening 211a. In this way, while the first plug-in portion 12 is engaged with the first mounting cavity 211, the filter strip 1 includes a side edge located on the transparent cover of the optical touch device, thereby expanding the emission.

[0172] and the effective angle of the light incident on the optical touch component 4, thereby reducing the touch height.

[0173] In another example, referring to Figure 7 , Figure 7 FIG. 1 shows a schematic structural diagram of a filter strip 1 provided in another embodiment of the present disclosure. Figure 7 As shown, the connecting portion 15 is connected to the third surface 113 of the filter strip body 11, and the second plug-in portion 14 is connected to the first surface 111. In this case, the connecting portion 15 can be close to the connection between the second surface 112 and the third surface 113. In this way, the connecting portion 15 can be prevented from increasing the distance between the filter strip body 11 and the transparent cover of the optical touch device. In addition, through the connecting portion 15, a part of the filter strip 1 can be located on the side of the transparent cover, thereby expanding the effective angle of the light emitted and incident on the optical touch component 4 and reducing the touch height.

[0174] In another example, referring to Figure 5 The connecting portion 15 is connected to the connection between the second surface 112 and the third surface 113, and the second plug-in portion 14 is located on the first surface 111. At this time, the connecting portion 15 can receive the light signal emitted from the optical touch component 4 and refract it to be parallel to the display screen of the optical touch device. In this way, the light signal in the area where the connecting portion 15 is located can also be emitted to the other side, or the light signal on the other side can be received, thereby reducing the touch height of the optical touch device.

[0175] Specifically, if Figure 2As shown, when the connecting portion 15 is connected to the connection between the second surface 112 and the third surface 113, the connecting portion 15 is close to the side of the transparent cover of the optical touch device. This allows light with a larger exit angle in the optical touch component 4 to be refracted at the connecting portion, thereby allowing the exiting light to propagate to the optical touch component 4 on the opposite side. Similarly, light close to the side of the transparent cover that is adjacent to the filter bar body 11 can be refracted by the connecting portion 15 to the position where the optical touch component 4 is located after entering the filter bar 1. This increases the effective exit angle and the effective reception angle of the optical signal. Specifically, the single-side effective angle can be increased by 7.5 degrees, and the touch height of the optical touch device can be reduced by 0.3 to 0.4 mm.

[0176] In one embodiment, continue to refer to Figure 3 , the profile frame 2 includes:

[0177] The first profile frame includes a first sub-frame 22 and a second sub-frame 23 connected to each other, wherein the first sub-frame 22 and the second sub-frame 23 are connected to form an L shape;

[0178] The second profile frame 21 is connected to the second sub-frame 23 and is located on the same side of the second sub-frame 23 as the first sub-frame 22;

[0179] The accommodating space 3 is located in the space enclosed by the first profile frame and the second profile frame 21. The first installation cavity 211 is opened on the side of the second profile frame 21 away from the second sub-frame 23. The second installation cavity 221 is opened on the side of the second profile frame 21 away from the second sub-frame 23.

[0180] It is opened on the side of the first sub-frame 22 facing the second profile frame 21 .

[0181] In this embodiment, the first sub-frame 22 and the second sub-frame 23 are integrally formed, and the first profile frame and the second profile frame 21 are integrally formed. The first sub-frame 22 is opposed to the second profile frame 21, so that the first mounting cavity 211 can be located in the second profile frame 21, facing away from the second sub-frame 23. This allows the opening direction of the first opening 211a of the first mounting cavity 211 to be aligned with the opening direction of the second opening 31. The second mounting cavity 221 is located in the first sub-frame 22 and faces the second profile frame 21. This allows the embedded filter strip to be located in the second opening 31, and facilitates positioning of the filter strip 1 through the first mounting cavity 211 and the second mounting cavity 221, thereby ensuring the stability of the filter strip 1.

[0182] The optical touch frame provided by the embodiment of the present disclosure is provided with a first mounting cavity 211 on the profile outer frame 2, and the first opening 211a of the first mounting cavity 211 is parallel to the light emission direction of the filter strip 1, so that the first plug-in portion 12 of the filter strip 1 is plugged into the first mounting cavity 211 on the side of the display screen, so that the direction of the light emitted by the optical touch component 4 on the side of the display screen is refracted by the filter strip 1 to be parallel to the display screen, thereby reducing the touch height of the optical touch frame; at the same time, because the filter strip 1 also includes a water barrier 13 that blocks the first gap 231 between the second wall 211c in the first mounting cavity 211 and the first plug-in portion 12 The water retaining strip 13 can work together with the water storage tank 212 in the first installation cavity 211 to prevent external water from flowing into the accommodating space 3 of the profile frame 2 for accommodating the optical touch assembly 4, thereby improving the waterproof performance of the optical touch frame; in addition, since the size of at least part of the space inside the first installation cavity 211 is larger than the size of the first opening 211a, and the size of the end of the first plug-in portion 12 away from the filter strip 1 is larger than the size of the end of the first plug-in portion 12 close to the filter strip 1, the first plug-in portion 12 can be confined within the first installation cavity 211, preventing the filter strip 1 from jumping out of the profile frame 2 when impacted, thereby improving the stability of the filter strip 1.

[0183] Based on the same inventive concept, the embodiment of the present disclosure further provides an optical touch frame, which is provided with a water barrier 13 connected to the filter bar 1. The water barrier 13 is used to directly block the water flowing into the gap between the filter bar 1 and the transparent cover of the optical touch device. Specifically, continue to refer to Figure 2 The optical touch frame includes:

[0184] The profile outer frame 2 has a second wall 211c;

[0185] The filter strip 1 includes a first plug-in portion 12 , and a first gap 231 is defined between the first plug-in portion 12 and the second wall 211 c ;

[0186] The water retaining bar 13 is connected to the filter bar 1 , and the water retaining bar 13 covers the first gap 231 .

[0187] In this embodiment, the first plug-in portion 12 is plugged into the profile outer frame 2, and the second wall 211c is a wall surface of the profile outer frame 2 adjacent to the first plug-in portion 12. Since a first gap 231 is formed between the first plug-in portion 12 and the second wall 211c, water can flow into the profile outer frame 2 along the first gap 231. Therefore, a water retaining strip 13 connected to the filter strip 1 is used to block the first gap 231, thereby preventing water from entering the profile outer frame 2 along the first gap 231. The water retaining strip 13 is made of a hydrophobic material, which can be the same material as the filter strip 1.

[0188] The profile outer frame 2 has a first installation cavity 211 in which the first plug-in portion 12 is embedded. The first gap 231 is formed between the second wall 211 c of the first installation cavity 211 and the first plug-in portion 12 .

[0189] In this embodiment, the second wall 211c is a side wall of the first installation cavity 211. When the first plug-in portion 12 is plugged into the first installation cavity 211, there is a gap between the filter strip 1 and the transparent cover plate through which water can flow. The first installation cavity 211 is provided near the gap between the transparent cover plate and the filter strip 1, and there is a first gap 231 between the first installation cavity 211 and the first plug-in portion 12. This allows water to flow into the first installation cavity 211. Thus, the water retaining strip 13 can be connected to the filter strip 1 to block the water flow flowing along the filter strip 1, and the water retaining strip 11 can block the first gap 231. In this way, water can be prevented from flowing into the first installation cavity 211 along the first gap 231.

[0190] For other structures of the optical touch frame, reference can be made to the optical touch frame described in any of the above embodiments, such as, in the profile frame 2 of the optical touch frame, the first installation cavity 211 includes a water tank 212, and the profile frame 2 of the optical touch frame includes a first installation cavity 211 and a second installation cavity 221, etc.

[0191] The optical touch frame provided in the embodiment of the present disclosure is adopted, and a water retaining bar 13 is set, and the water retaining bar 13 blocks the first gap 231 between the first installation cavity 211 and the first plug-in part 12, so as to block water from entering the first installation cavity 211, prevent water from flowing along the first installation cavity 211 into the accommodating space 3 and damaging the optical touch component 4, thereby improving the waterproof performance of the optical touch frame.

[0192] Based on the same inventive concept, the present disclosure also provides a display device, referring to Figure 8 , Figure 8 FIG. 1 shows a schematic structural diagram of a display device provided by an embodiment of the present disclosure, such as Figure 8 As shown, the display device specifically includes:

[0193] Optical touch component 4, used for emitting or receiving touch light signals;

[0194] And, the optical touch frame 100 as described in any of the above embodiments,

[0195] The optical touch assembly 4 is located in the receiving space 3 of the profile outer frame 2 of the optical touch frame 100 .

[0196] In this embodiment, Figure 2 and Figure 8As shown, the optical touch component 4 is located in the accommodating space 3 enclosed by the profile frame 2 and the filter strip 1 of the optical touch frame 100, and the light emitting direction of the optical touch component 4 is toward the filter strip 1. In this way, the filter strip 1 can be used to refract the light signal emitted by the optical touch component 4 so that the light is emitted parallel to the display screen. Among them, since the first opening 211a of the first mounting cavity 211 in the profile frame is parallel to the light emitting direction of the filter strip 1, the first plug-in portion 12 of the filter strip 1 is plugged into the first mounting cavity 211 on the side of the display screen, thereby reducing the touch height of the display device.

[0197] Specifically, compare Figure 1 and Figure 8 In the related art, due to the obstruction of the connection position between the filter strip 1′ and the profile frame 2′, the filter strip can only be incident from the front of the display screen. This causes part of the light emitted by the optical touch component 4 to be reflected at the display screen position of the optical touch device due to the large incident angle, thereby causing the touch height of the optical touch device to be higher. In this embodiment, the first plug-in portion 12 and the water retaining bar 13 are located on the side of the transparent cover 200, so that the area of ​​the first plug-in portion 11 with a larger exit angle close to the filter strip 1 is refracted, thereby allowing the light signal to propagate to the optical touch component on the opposite side. Similarly, the light signal close to the side of the transparent cover 200 that is close to the filter strip 1 can be refracted by the filter strip 1 to the position of the optical touch component 4 after entering the filter strip 1, which increases the effective exit angle and the effective reception angle of the light signal. Specifically, the single-sided effective angle can be increased by 7.5 degrees, and the touch height of the display device can be reduced by 0.3 to 0.4 mm.

[0198] In one embodiment, continue to refer to Figure 8 , the display device further includes:

[0199] A transparent cover plate 200, wherein a side surface 220 of the transparent cover plate 200 is disposed opposite to the first mounting cavity 211 of the profile outer frame 2;

[0200] The filter strip 1 further includes a water retaining strip 13 , and the water retaining strip 13 is located between the side surface 220 of the transparent cover plate 200 and the profile outer frame 2 .

[0201] In this embodiment, a portion of the transparent cover plate 200 may be located in the gap between the filter strip 1 and the profile outer frame 2, such as Figure 8 As shown, the side of the filter strip 1 closest to the transparent cover plate 200 can contact the light-emitting surface 210 of the transparent cover plate 200. In this way, the light signal emitted by the optical touch component 4 can be refracted parallel to the light-emitting surface 210, thereby enabling the touch position to be determined based on the light signal received on the other side, thereby achieving optical touch. The side surface 220 of the transparent cover plate 200 can be the side surface of the transparent cover plate 200 close to the profile outer frame 2.

[0202] Among them, since the filter strip 1 can also include a water retaining strip 13, in one example, the water retaining strip 13 can be located between the side 220 of the transparent cover 200 and the first mounting cavity 211 of the profile frame 2, so that a partial area of ​​the filter strip 1 is located on the side 220 of the transparent cover 200, which enables the light signal with a larger angle emitted by the optical touch component 4 to be refracted to be parallel to the light emitting surface 210, and then emitted, thereby reducing the touch height of the display device.

[0203] Among them, continue to refer to Figure 8 , the display device further includes:

[0204] The connecting strip 300 includes a bearing surface 310 and a connecting surface 320 . The bearing surface 310 is connected to the surface of the transparent cover 200 , and the connecting surface 320 is connected to the profile outer frame 2 .

[0205] The filter strip 1 further includes a filter strip body 11 , a first plug-in portion 12 connected to the filter strip body 11 , and the first plug-in portion 12 is embedded in the first mounting cavity 211 ;

[0206] The side of the transparent cover plate 200 facing away from the carrying surface 310 is in contact with the filter bar body 11 .

[0207] In this embodiment, the light-emitting surface 210 of the transparent cover plate 200 contacts the filter strip body 11, while the surface on the side facing away from the light-emitting surface 210 is connected to the supporting surface 310. In this way, the fixing connecting strip 300 does not affect the light-emitting surface 210, and the connecting surface 320 is connected to the profile frame 2, thereby improving the connection stability between the transparent cover plate 200 and the profile frame 2.

[0208] In this embodiment, the connecting strip 300 can also mitigate the impact force exerted on the filter strip 1 when the transparent cover plate 200 falls, reducing the risk of the filter strip 1 detaching from the profile frame 2. When the first plug-in portion 12 engages with the first mounting cavity 211, the first mounting cavity 211 can restrict the position of the first plug-in portion 12 and support the first plug-in portion 12 when the filter strip 1 is impacted. The second mounting cavity 221 can support the second plug-in portion 14 when the filter strip 1 is impacted. This allows the filter strip 1 to withstand greater impact forces than existing structures, thereby reducing the coverage area of ​​the supporting surface 310 of the connecting strip 300, thereby reducing the manufacturing cost of the display device. For example, the coverage area of ​​the connecting strip 300 is reduced by 70% to 80% compared to the coverage area of ​​connecting strips in the related art. In this case, the optical touch bezel can still prevent the filter strip 1 from detaching.

[0209] The connecting strip 300 is used to fix the transparent cover plate 200. In one example, the bearing surface 310 of the connecting strip 300 is connected to the transparent cover plate 200 via a buffer block 330 or VHB (Very High Bond) adhesive. When VHB adhesive is used, the transparent cover plate 200 has better impact resistance, thereby preventing the filter strip 1 from detaching. The buffer block 330 can be made of silicone or foam. Silicone or foam has a lower cost, which can reduce the manufacturing cost of the display device and ensure the stability of the filter strip 1.

[0210] In one embodiment, continue to refer to Figure 8 A third gap is formed between the connecting strip 300, the side surface 220 of the transparent cover plate 200 and the first installation cavity 211, and the water retaining strip 13 is located in the third gap.

[0211] In this embodiment, there is a gap between the side 220 of the transparent cover plate 200 and the first mounting cavity 211, and since the connecting strip 300 is connected to the transparent cover plate 200 via a buffer block, there is also a gap between the transparent cover plate 200 and the connecting strip 300. Thus, a third gap is formed between the side 220 of the transparent cover plate 200 and the first mounting cavity 211 and the connecting strip 300. The third gap can be understood as a space enclosed by the side 220 of the transparent cover plate 200, the first mounting cavity 211, and the connecting strip 300. At this time, the water retaining strip 13 can be located in the third gap so that it blocks the first mounting cavity 211 and guides the water flow in the direction of the connecting strip 300, so that the water flow can flow out of the display device, thereby achieving a waterproof function.

[0212] In one embodiment, continue to refer to Figure 8 There is a gap between the water retaining strip 13 and the side surface 220 of the transparent cover plate 200 , and there is a gap between the water retaining strip 13 and the connecting strip 300 .

[0213] Specifically, in the display device, a designed gap is inevitably present between the filter strip 1 and the light-emitting surface 210 of the transparent cover plate 200. In this way, a gap can be provided between the water retaining strip 13 and the side surface 220. In this way, the water flowing in from the gap between the filter strip 1 and the light-emitting surface 210 can flow along the water retaining strip 13, and then flow along the water retaining strip 13 into the gap between it and the connecting strip 300. Since there is also a tiny gap at the portion where the connecting strip 300 is connected to the profile outer frame 2, the water flowing in from the water retaining strip 13 can be gradually guided along the gap to the outside of the display device.

[0214] In this embodiment, the first installation cavity 211 may have a water storage tank 212 or not. The gap between the side of the connecting strip 300 close to the profile outer frame 2 and the profile outer frame 2 can allow the water flowing into the profile outer frame 2 to be diverted out of the profile outer frame 2 through the gap. In the case of the presence of the water storage tank 212, the gap between the side of the connecting strip 300 close to the profile outer frame 2 and the profile outer frame 2 can be either free of gap or present, so that the water flowing into the profile outer frame 2 can be diverted into the storage tank.

[0215] The water tank 212 is prevented from overflowing into the receiving space 3 and affecting the performance of the optical touch component 4 .

[0216] For example, refer to Figure 9 , Figure 9 FIG. 1 shows a schematic diagram of the flow direction of water in the display device provided by the embodiment of the present disclosure, as shown in FIG. Figure 9 As shown, the direction of the arrow is the flow direction of water after entering the display device of the embodiment of the present disclosure. The water flows from the gap between the light-emitting surface 210 of the transparent cover plate 200 and the filter bar 1 into the gap between the side surface 220 of the transparent cover plate 200 and the water retaining bar 13, and is thereby blocked by the water retaining bar 13 of the filter bar 1 and the flow direction is changed. The water flows along the water retaining bar 13 and gradually flows to the gap between the connecting bar 300 and the profile frame 2, and flows along the extension direction of the gap between the connecting bar 300 and the profile frame 2 until it flows out of the profile frame 2.

[0217] When the water flow rate entering the display device is large, the first installation cavity 211 can be provided with a water storage tank 212 to store the water that has not flowed out of the profile outer frame 2. Figure 10 , Figure 10 FIG. 1 shows a schematic diagram of the flow direction of water in a display device provided in another embodiment of the present disclosure, as shown in FIG. Figure 10 As shown, water flows along the gap between the light-emitting surface 210 of the transparent cover plate 200 and the filter strip 1, and then flows into the gap between the side surface 220 of the transparent cover plate 200 and the water retaining bar 13. Blocked by the water retaining bar 13, the water flows along the water retaining bar 13 to the gap between the connecting bar 300 and the profile outer frame 2. At this time, due to the large water flow rate, some of the water may flow along the gap between the water retaining bar 13 and the profile outer frame 2 and enter the first installation cavity 211. The water then flows along the wall of the first installation cavity 211 into the water storage tank 212, thereby preventing the water from flowing from the first installation cavity 211 into the cavity enclosed by the profile outer frame 2 and the filter strip 1, thereby preventing the optical touch assembly 4 in the cavity from being damaged. Since the water storage tank 212 is connected to the first installation cavity 211, the first installation cavity 211 has a first opening 211a that is connected to the outside world, allowing the water accumulated in the water storage tank 212 to evaporate and escape, thus preventing the water from continuing to accumulate in the water storage tank 212.

[0218] The display device provided by the embodiment of the present disclosure sets a first mounting cavity 211 by the profile outer frame 2 of the optical touch frame 100, and makes the first opening 211a of the first mounting cavity 211 parallel to the opening direction of the second opening 31 of the accommodating space 3, so that the first plug-in portion 12 of the filter strip 1 needs to be plugged into the first mounting cavity 211 at the side of the display screen, so that the direction of the light emitted by the optical touch component 4 at the side of the display screen is refracted by the filter strip 1 to be parallel to the display screen, thereby reducing the touch height of the display device; at the same time, because the filter strip 1 also includes a first gap 231 between the second wall 211c in the first mounting cavity 211 and the first plug-in portion 12, The water retaining bar 13 can work together with the water storage tank 212 in the first installation cavity 211 to prevent external water from flowing into the accommodating space 3 of the profile frame 2 for accommodating the optical touch component 4, thereby improving the waterproof performance of the optical touch frame 100; in addition, since the size of at least part of the space inside the first installation cavity 211 is larger than the size of the first opening 211a, and the size of the end of the first plug-in portion 12 away from the filter bar 1 is larger than the size of the end of the first plug-in portion 12 close to the filter bar 1, the first plug-in portion 12 can be confined within the first installation cavity 211, preventing the filter bar 1 from jumping out of the profile frame 2 when impacted, thereby improving the stability of the filter bar 1.

[0219] The display device provided by the present disclosure is described below with reference to a specific example:

[0220] Reference Figure 8 and Figure 11 ,in, Figure 11 Shown Figure 8 The overall structural diagram of the display device shown in FIG. Figure 8 and Figure 11As shown, the space enclosed by the filter strip 1 and the profile frame 2 accommodates the optical touch assembly 4. The profile frame 2 includes a first mounting cavity 211 and a second mounting cavity 221. The first mounting cavity 211 is close to the transparent cover 200, and the second mounting cavity 221 is located on the side of the optical touch assembly 4 away from the transparent cover 200. A water storage tank 212 is provided at the bottom of the first mounting cavity 211, and the water storage tank 212 is connected to the first mounting cavity 211; the first mounting cavity 211 has a first opening 211a, the opening direction of which is parallel to the light emitting direction of the filter strip 1, and the second mounting cavity 221 has a third opening 221a, the opening of which is parallel to the light emitting direction of the filter strip 1. The direction is orthogonal to the light emitting direction of the filter strip 1, and the size of the partial space of the first mounting cavity 211 is larger than the size of the first opening 211a; the filter strip 1 includes a first plug-in portion 12 and a second plug-in portion 14, the first plug-in portion 12 is embedded in the first mounting cavity 211, and the second plug-in portion 14 is embedded in the second mounting cavity 221, and the size of the first plug-in portion 12 close to the end of the filter strip 1 is smaller than the size of the end away from the filter strip 1; wherein, the filter strip 1 further includes a water retaining strip 13 that blocks the first gap 231 between the second wall 211c of the first mounting cavity 211 and the first plug-in portion 12.

[0221] Among them, the display device is used to conduct a whole-device tipping experiment, and an external force is applied to the transparent cover plate 200 to cause it to tip over. At this time, the filter strip 1 is subjected to the impact force of the transparent cover plate 200. There is a force point B in the first plug-in portion 12, and there is a force point A in the second plug-in portion 14. The force point A can provide support for the filter strip 1, and the force point B plays a buffering role, reducing the impact force on the filter strip 1. In addition, since the size of the end of the first plug-in portion 12 away from the filter strip 1 is larger than the size of the end close to the filter strip 1, and the size of the partial space inside the first mounting cavity 211 in the direction orthogonal to the light emitting direction of the filter strip 1 is larger than the size of the first opening 211a in the same direction, the first mounting cavity 211 can display the position of the filter strip 1, thereby preventing the filter strip 1 from jumping out of the profile frame 2, so that the display device can withstand a large impact force without the filter strip 1 jumping out.

[0222] Furthermore, when this structure is adopted, the performance requirements of the connecting bar 300 in the display device are reduced, and the bonding performance requirements between the transparent cover plate 200 and the connecting bar 300 are reduced, so that the area of ​​the connecting bar 300 can be reduced by 70% to 80%. The connecting bar 300 and the transparent cover plate 200 can be connected with a silicone block or foam, thereby reducing the manufacturing cost of the optical touch device.

[0223] When external water flows into the display device, the water flows through the gap between the filter strip 1 and the transparent cover plate 200 into the optical touch frame 100, and is blocked by the water retaining bar 13 of the filter strip 1, and flows along the extension direction of the water retaining bar 13. Since the water retaining bar 13 extends toward the connecting bar 300, the water flowing along the extension direction of the water retaining bar 13 is guided to the gap between the profile frame 2 and the connecting bar 300, and flows along the gap until it flows out of the profile frame 2. Thus, the display device has a waterproof function, preventing water from entering the optical touch component 4 located in the space surrounded by the filter strip 1 and the profile frame 2.

[0224] Among them, when the water flow is large, part of the water flow may be accumulated in the gap between the profile outer frame 2 and the connecting strip 300, so that excess water flows into the first installation cavity 211 along the gap between the water retaining strip 12 and the profile outer frame 2. At this time, part of the water flow that flows into the gap between the connecting strip 300 and the profile outer frame 2 flows along the gap between the connecting strip 300 and the profile outer frame 2 and is guided to the outside of the display device, while part of the water flow that enters the first installation cavity 211 flows along the wall surface of the first installation cavity 211 to the water storage tank 212 for accumulation. Since the water storage tank 212 is connected to the first installation cavity 211, the first installation cavity 211 is connected to the outside world, so that the water accumulated in the water storage tank 212 can be evaporated and removed, further improving the waterproof performance of the display device.

[0225] Compare Figure 1 and Figure 11 In the related art, the side of the transparent cover is blocked by the profile frame 2', so that among the light emitted by the optical touch component 4, the light with a larger angle can only be emitted from the front of the filter strip 1', which causes part of the light to be reflected by the display screen of the optical touch device, thereby making the touch height of the optical touch device higher. In the display device of this embodiment, Figure 8 For example, light with a larger angle can enter the side of the first plug-in portion 12 close to the filter strip 1 and be emitted parallel to the transparent cover 200, so that it can be transmitted to the infrared receiver on the opposite side. Similarly, light with a lower height incident from the opposite side can be refracted by the filter strip 1, so that it can be transmitted to the optical touch component 4. As a result, the effective emission angle and the effective reception angle of the light are both increased, thereby reducing the touch height of the display device.

[0226] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
