Description

Technical Field

[0001] This application belongs to the field of display device technology, and more specifically, relates to a touch screen and display device. Background Technology

[0002] A touchscreen is a human-computer interaction device that converts touch actions into electronic signals, thereby enabling direct control of electronic devices.

[0003] Touchscreens in related technologies typically use infrared touch to achieve touch operation. The touch operation is performed on the touch outer layer of the touchscreen, which has a touch surface and a back surface that are set opposite to each other. Meanwhile, infrared transmitters and infrared receivers are installed on opposite sides of the touch outer layer, and the infrared light emitted by the infrared transmitter to the infrared receiver is located on the side of the touch surface away from the back surface.

[0004] To ensure the touch performance of the touch screen, the outer touch layer is usually recessed in the direction away from infrared light. However, the shape of the outer touch layer makes it easy for the infrared receiver to sense the touch action before the touch input component lands on the outer touch layer. This "suspended touch" phenomenon will cause the touch action of the touch input component to not match the actual feedback, thus affecting the touch experience. Utility Model Content

[0044] As described in the background section, a touchscreen is a human-computer interaction device that converts touch actions into electronic signals, thereby enabling direct control of electronic devices. Touchscreens in related technologies typically employ infrared touch control for operation. Touch operations occur on the outer touch layer of the touchscreen, which has a touch surface and a back surface positioned opposite each other. An infrared transmitter and receiver are mounted on opposite sides of the outer touch layer, with the infrared light emitted by the transmitter to the receiver located on the touch surface away from the back surface. To ensure touch performance, the outer touch layer is usually recessed away from the infrared light source. However, this shape can cause the infrared receiver to detect touch actions even before the touch input component lands on the outer touch layer. This "suspended touch" phenomenon results in a mismatch between the touch input component's action and the actual feedback, thus affecting the touch experience.

[0045] Reference Figures 1 to 8To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides a touch screen, which includes a touch outer layer 100, a first touch detection unit, and a mounting unit 300. The touch outer layer 100 has a touch surface 110 and a back surface 120 disposed opposite to each other. The first touch detection unit includes a first transmitter 210 and a first receiver 220. The first transmitter 210 is capable of emitting a first detection light, and the first receiver 220 is capable of receiving the first detection light. The propagation path of the first detection light between the first transmitter 210 and the first receiver 220 forms a first detection path, which is located on the side of the touch surface 110 away from the back surface 120. The touch outer layer 100 is mounted on the mounting unit 300 and protrudes toward the first detection path under a first preset thrust applied by the mounting unit 300. The first preset thrust is directed toward the side of the touch surface 110 away from the back surface 120.

[0046] In this embodiment, the touchscreen is used in conjunction with a touch input component 500, which is typically a user's finger, stylus, or other tool for touch operation. The touch outer layer 100 is a cover glass made of tempered glass and is mounted on the mounting portion 300. In other embodiments, the touch outer layer 100 may also be made of plastic, ceramic, metal, or other composite materials, depending on actual needs. The first transmitter 210 is typically an infrared plate with an infrared transmitter, and the first receiver 220 is typically an infrared plate with an infrared receiver. Infrared light is formed as the first detection light, and the propagation path of the first detection light is straight. In other embodiments, the first detection light may also be a laser or other light that can be used to detect touch operation. In this case, the specific structure of the first transmitter 210 and the first receiver 220 may be determined according to actual detection needs, and no specific limitations are imposed here. Furthermore, in some other embodiments, the first transmitter 210 may also be an infrared plate with both an infrared transmitter and an infrared receiver, and the first receiver 220 may also be an infrared plate with both an infrared transmitter and an infrared receiver. The mounting portion 300 may have a force-applying structure located on the side of the touch outer layer 100 away from the first detection path and protruding toward the first detection path. At the same time, the force-applying structure can apply a first preset thrust to the touch outer layer 100 by contacting the back surface 120, so that the touch outer layer 100 protrudes toward the first detection path. Figure 3 , Figure 5 as well as Figure 6 The dashed lines in the diagram represent the first detection route.

[0047] In this application, the touch outer layer 100 protrudes towards the first detection path under the action of a first preset thrust applied by the mounting portion 300. This design effectively reduces the distance between the touch outer layer 100 and the first detection path, so that the touch input component 500, such as the user's finger or stylus, is only detected by the first touch detection unit when it is closer to the touch outer layer 100. This improvement makes the touch action of the touch input component 500 more consistent with the actual feedback, thus making the touch action of the touch input component 500 more in line with natural writing. By using the mounting portion 300 and the touch outer layer 100 in combination, the touch experience of the touch screen is effectively improved while ensuring the touch performance of the touch screen.

[0048] Reference Figures 3 to 6 In one embodiment, the mounting portion 300 includes a first mounting frame 310, on which one of a first transmitter 210 and a first receiver 220 is mounted; the first mounting frame 310 has a first mounting space 311a, and a portion of the structure of the touch outer layer 100 is mounted within the first mounting space 311a. The first mounting space 311a has a first mounting surface 312b and a first mounting opening 311b, and a portion of the structure of the touch outer layer 100 is mounted into the first mounting space 311a through the first mounting opening 311b; the first mounting surface 312b is inclined from the back surface 120 to the touch surface 110 toward the first mounting opening 311b, and applies a first preset thrust to the touch outer layer 100 by contacting the back surface 120.

[0049] In this embodiment, the first transmitter 210 is mounted on the first mounting frame 310. In other embodiments, the first receiver 220 may be mounted on the first mounting frame 310. The direction from the touch surface 110 to the back surface 120 is parallel to the thickness direction of the touch screen and perpendicular to the first detection path. The first mounting surface 312b is the inner surface within the first mounting space 311a. The first mounting surface 312b is a smoothly transitioned slope and gradually slopes towards the first mounting opening 311b from the back surface 120 to the touch surface 110. Furthermore, the first mounting surface 312b remains in contact with the back surface 120 to ensure that the first mounting surface 312b applies a uniformly distributed first preset thrust to the touch outer layer 100. In other embodiments, the first mounting surface 312b may also be a non-smoothly transitioned slope, such as a slope with multiple protrusions.

[0050] According to the principles of mechanics, the first preset thrust is perpendicular to the first mounting surface 312b. In this application, the first mounting surface 312b is inclined from the back surface 120 to the touch surface 110 towards the first mounting opening 311b. This inclined design ensures that when the first preset thrust is applied to the touch outer layer 100, it is actually transmitted from the back surface 120 to the touch surface 110 at a certain angle away from the first mounting opening 311b. The first preset thrust is transmitted to the touch outer layer 100 through the back surface 120, causing the touch outer layer 100 to shift in this direction and protrude towards the first detection path. By adopting the above design, the shape of the touch outer layer 100 is effectively changed, so that the touch input component 500, such as the user's finger or stylus, is only detected by the first touch detection unit when it is closer to the touch outer layer 100, effectively improving the touch performance and touch accuracy of the touch screen.

[0051] Reference Figures 3 to 6 In one embodiment, the first mounting space 311a further has a second mounting surface 311c, which is located between the first detection route and the first mounting surface 312b and is disposed opposite to the first mounting surface 312b; the second mounting surface 311c is inclined from the back surface 120 to the touch surface 110 toward the mounting opening and contacts the touch surface 110.

[0052] In this embodiment, the second mounting surface 311c is the inner surface within the first mounting space 311a. The second mounting surface 311c is a smoothly transitioning slope, gradually sloping towards the first mounting opening 311b from the back surface 120 to the touch surface 110. Furthermore, the second mounting surface 311c remains in contact with the touch surface 110 to ensure that the second mounting surface 311c applies a uniformly distributed pressing pressure to the touch outer layer 100. In other embodiments, the second mounting surface 311c may also be a non-smoothly transitioning slope, such as a slope with multiple protrusions.

[0053] The second mounting surface 311c works in conjunction with the first mounting surface 312b to not only limit the movement of the touch outer layer 100 within the mounting space and enhance the stability of the touch outer layer 100 on the mounting part 300, but also to provide additional support to help maintain the shape of the touch outer layer 100, thereby preventing changes in the shape of the touch outer layer 100 from affecting the touch performance of the touch screen.

[0054] Reference Figure 3 and Figure 5 In the first embodiment, the first detection route is parallel to the first preset direction, and the thickness of the touch outer layer 100 remains unchanged; the first mounting surface 312b has a first adjustment angle with the first preset direction, the first adjustment angle first increases and then decreases along the second preset direction, and the second preset direction is perpendicular to the first preset direction.

[0055] In this embodiment, the first preset direction is parallel to the length direction of the touch outer layer 100, and the second preset direction is parallel to the width direction of the touch outer layer 100. The first mounting frame 310 is set along the second preset direction. In other embodiments, the first preset direction may also be parallel to the width direction of the touch outer layer 100, and the second preset direction may be parallel to the length direction of the touch outer layer 100. The first mounting surface 312b is a complete surface. The first adjustment angle gradually increases and then gradually decreases along the second preset direction to ensure that the touch outer layer 100 achieves a smooth protrusion, reducing user discomfort and optimizing the touch performance of the touch screen. The reason for setting a larger angle in the middle of the touch outer layer 100 is that the middle part of the touch outer layer 100 is less affected by the clamping force compared to the edge part. At the same time, based on the influence of the gravity of the touch outer layer 100 itself, the middle part of the touch outer layer 100 is less prone to deformation. Therefore, a larger angle is set in the middle of the touch outer layer 100. This design, which keeps the thickness of the outer touch layer 100 unchanged, simplifies the manufacturing process, improves production efficiency and yield while reducing production costs, and also helps to reduce user discomfort and optimize the touch performance of the touch screen.

[0056] The above design causes the distance between the touch surface 110 and the first detection path to first decrease and then increase along the second preset direction. This not only allows the middle part of the touch outer layer 100 to be closer to the first detection path, thus improving the touch experience of the touch screen while ensuring its touch performance, but also helps to disperse the stress on the touch outer layer 100, reduce stress concentration, improve the deformation resistance of the touch outer layer 100, and extend the service life of the touch outer layer 100.

[0057] Reference Figure 3 and Figure 5 In the first embodiment, the first detection route is parallel to the first preset direction, and the thickness of the touch outer layer 100 remains unchanged; the second mounting surface 311c has a second adjustment angle with the first preset direction, the second adjustment angle first increases and then decreases along the second preset direction, and the second preset direction is perpendicular to the first preset direction.

[0058] In this embodiment, the second mounting surface 311c is a complete surface, and the second adjustment angle gradually increases and then gradually decreases along the second preset direction. The reason for setting a larger angle in the middle of the touch outer layer 100 is that the middle part of the touch outer layer 100 is less affected by the clamping force compared to the edge part. At the same time, due to the influence of the gravity of the touch outer layer 100 itself, the middle part of the touch outer layer 100 is less prone to deformation. Therefore, a larger angle is set in the middle of the touch outer layer 100. The second mounting surface 311c designed above fits tightly with the first mounting surface 312b, which not only restricts the movement of the touch outer layer 100 in the mounting space and enhances the stability of the touch outer layer 100 on the mounting part 300, but also provides additional support to help maintain the shape of the touch outer layer 100, thereby preventing the touch performance of the touch screen from being affected by changes in the shape of the touch outer layer 100.

[0059] Reference Figure 3 and Figure 5 In the second embodiment, the first detection route is parallel to the first preset direction, and the thickness of the touch outer layer 100 remains unchanged; the first mounting surface 312b has a first adjustment angle with the first preset direction, the first adjustment angle first increases along the second preset direction, then remains unchanged, and then decreases, and the second preset direction is perpendicular to the first preset direction.

[0060] In this embodiment, the first preset direction is parallel to the length direction of the touch outer layer 100, and the second preset direction is parallel to the width direction of the touch outer layer 100. The first mounting frame 310 is set along the second preset direction. In other embodiments, the first preset direction may also be parallel to the width direction of the touch outer layer 100, and the second preset direction may be parallel to the length direction of the touch outer layer 100. The first mounting surface 312b is a complete surface. The first adjustment angle gradually increases along the second preset direction, then remains constant, and then gradually decreases to ensure that the touch outer layer 100 achieves a smooth protrusion, reducing user discomfort and optimizing the touch performance of the touch screen. The reason for setting a larger angle in the middle of the touch outer layer 100 is that the middle part of the touch outer layer 100 is less affected by the clamping force compared to the edge part. At the same time, based on the influence of the gravity of the touch outer layer 100 itself, the middle part of the touch outer layer 100 is less prone to deformation. Therefore, a larger angle is set in the middle of the touch outer layer 100.

[0061] The above design causes the distance between the touch surface 110 and the first detection route to first decrease, then remain constant, and then increase along the second preset direction. This not only allows the middle part of the touch outer layer 100 to be closer to the first detection route, thus improving the touch experience of the touch screen while ensuring its touch performance, but also helps to disperse the stress on the touch outer layer 100, reduce stress concentration, improve the deformation resistance of the touch outer layer 100, and extend the service life of the touch outer layer 100.

[0062] Reference Figure 3 and Figure 5 In the second embodiment, the first detection route is parallel to the first preset direction, and the thickness of the touch outer layer 100 remains unchanged; the second mounting surface 311c has a second adjustment angle with the first preset direction, the second adjustment angle first increases along the second preset direction, then remains unchanged and then decreases, and the second preset direction is perpendicular to the first preset direction.

[0063] In this embodiment, the second mounting surface 311c is a complete surface. The second adjustment angle gradually increases along the second preset direction, then remains constant, and then gradually decreases. The reason for setting a larger angle in the middle of the touch outer layer 100 is that the middle part of the touch outer layer 100 is less affected by the clamping force compared to the edge part. At the same time, due to the influence of the gravity of the touch outer layer 100 itself, the middle part of the touch outer layer 100 is less prone to deformation. Therefore, a larger angle is set in the middle of the touch outer layer 100. The second mounting surface 311c designed above fits tightly with the first mounting surface 312b, which not only restricts the movement of the touch outer layer 100 in the mounting space and enhances the stability of the touch outer layer 100 on the mounting part 300, but also provides additional support to help maintain the shape of the touch outer layer 100, thereby preventing the touch performance of the touch screen from being affected by changes in the shape of the touch outer layer 100.

[0064] Reference Figure 5 In one embodiment, the first adjustment angle is greater than 0° and less than or equal to 10°; the second adjustment angle is greater than 0° and less than or equal to 10°.

[0065] Reference Figures 3 to 6 In one embodiment, the second mounting surface 311c is parallel to the first mounting surface 312b. This design facilitates a tight fit between the first mounting surface 312b and the second mounting surface 311c, thereby not only helping to limit the movement of the touch outer layer 100 within the mounting space and helping to maintain the shape of the touch outer layer 100, but also facilitating the assembly of the touch outer layer 100 and the first mounting frame 310, reducing assembly difficulty and cost.

[0066] Reference Figures 3 to 6In one embodiment, the first mounting frame 310 includes a first frame 311 and a first clamping member 312. A second mounting surface 311c is disposed on the first frame 311. The first clamping member 312 is mounted on the first frame 311 and faces the second mounting surface 311c. A first clamping area is formed between the surface of the first clamping member 312 near the second mounting surface 311c and the second mounting surface 311c. A portion of the structure of the touch outer layer 100 is mounted within the first clamping area, which forms a first mounting space 311a. The surface of the first clamping member 312 near the second mounting surface 311c contacts the back surface 120 and forms a first mounting surface 312b.

[0067] In this application, the design of the first mounting frame 310, including the first frame body 311 and the first clamping member 312, effectively reduces the manufacturing difficulty and cost of the first mounting frame 310. Furthermore, to further reduce the manufacturing difficulty and cost of the first mounting frame 310, the first clamping member 312 is detachably mounted on the first frame body 311. Specifically, the first clamping member 312 can be detachably mounted on the first frame body 311 using connecting screws or snap-fit ​​methods.

[0068] Reference Figure 3 and Figure 6 In the third embodiment, the first detection route is parallel to the first preset direction, and the thickness of the touch outer layer 100 remains unchanged; the first clamping member 312 includes a plurality of first clamping bodies 312a spaced apart along the second preset direction, the second preset direction being perpendicular to the first preset direction; the surface of the first clamping body 312a near the second mounting surface 311c contacts the back surface 120; the surface of the first clamping body 312a near the second mounting surface 311c has a first clamping angle with the first preset direction, and the plurality of first clamping angles first increase and then decrease along the second preset direction.

[0069] In this embodiment, the first preset direction is parallel to the length direction of the touch outer layer 100, and the second preset direction is parallel to the width direction of the touch outer layer 100. The first mounting frame 310 is arranged along the second preset direction. In other embodiments, the first preset direction may also be parallel to the width direction of the touch outer layer 100, and the second preset direction may be parallel to the length direction of the touch outer layer 100. The first clamping body 312a is a glass strip, which is usually Z-shaped. In other embodiments, the shape of the first clamping body 312a may be determined according to actual needs. The second mounting surface 311c is a complete surface. The first clamping angle gradually increases and then gradually decreases along the second preset direction. The reason for setting a larger angle in the middle of the touch outer layer 100 is that the middle part of the touch outer layer 100 is less affected by the clamping force compared to the edge part. At the same time, due to the influence of the gravity of the touch outer layer 100 itself, the middle part of the touch outer layer 100 is less prone to deformation. Therefore, a larger angle is set in the middle of the touch outer layer 100.

[0070] The aforementioned design causes the distance between the touch surface 110 and the first detection path to first decrease and then increase along the second preset direction. This not only allows the middle part of the outer touch layer 100 to be closer to the first detection path, further improving the touch experience while ensuring the touch performance of the touch screen, but also helps to disperse stress on the outer touch layer 100, reduce stress concentration, improve the deformation resistance of the outer touch layer 100, and extend the service life of the outer touch layer 100. Simultaneously, the multiple first clamping bodies 312a help reduce the manufacturing difficulty and cost of the first clamping member 312, thereby reducing the manufacturing difficulty and cost of the touch screen.

[0071] Furthermore, to ensure a smooth protrusion of the touch outer layer 100, reducing user discomfort and optimizing touchscreen performance, in one specific embodiment, the angle range of the first adjustment angle near the edge of the first frame 311 is 0.5° to 3°, and the angle range of the first adjustment angle near the middle of the first frame 311 is 1° to 4°. The angles of the multiple first adjustment angles transition smoothly along a second preset direction. The size of the second adjustment angle is the same as the size of the first adjustment angle.

[0072] Reference Figure 3 and Figure 6In the third embodiment, the first detection route is parallel to the first preset direction, and the thickness of the touch outer layer 100 remains unchanged; the first clamping member 312 includes a plurality of first clamping bodies 312a spaced apart along the second preset direction, and the second preset direction is perpendicular to the first preset direction; the second mounting surface 311c has a second clamping angle with the first preset direction, and the second clamping angle first increases and then decreases along the second preset direction.

[0073] In this embodiment, the second mounting surface 311c is a complete surface, and the second clamping angle gradually increases and then gradually decreases along the second preset direction. The reason for setting a larger angle in the middle of the touch outer layer 100 is that the middle part of the touch outer layer 100 is less affected by the clamping force compared to the edge part. At the same time, due to the influence of the gravity of the touch outer layer 100 itself, the middle part of the touch outer layer 100 is less prone to deformation. Therefore, a larger angle is set in the middle of the touch outer layer 100. The second mounting surface 311c designed above fits tightly with the first mounting surface 312b, which not only restricts the movement of the touch outer layer 100 in the mounting space and enhances the stability of the touch outer layer 100 on the mounting part 300, but also provides additional support to help maintain the shape of the touch outer layer 100, thereby preventing the touch performance of the touch screen from being affected by changes in the shape of the touch outer layer 100.

[0074] In other embodiments, the first frame 311 may include a plurality of first frame bodies spaced apart along a second preset direction. The surface of the first frame body near the first mounting surface 312b contacts the touch surface 110. The surface of the first frame body near the first mounting surface 312b has a second clamping angle with the first preset direction. The plurality of second clamping angles first increase and then decrease along the second preset direction.

[0075] Reference Figure 3 and Figure 6 In the fourth embodiment, the first detection route is parallel to the first preset direction, and the thickness of the touch outer layer 100 remains unchanged; the first clamping member 312 includes a plurality of first clamping bodies 312a spaced apart along the second preset direction, and the second preset direction is perpendicular to the first preset direction; the surface of the first clamping body 312a near the second mounting surface 311c contacts the back surface 120; the surface of the first clamping body 312a near the second mounting surface 311c has a first clamping angle with the first preset direction, and the plurality of first clamping angles first increase along the second preset direction, then remain unchanged, and then decrease.

[0076] In this embodiment, the first preset direction is parallel to the length direction of the touch outer layer 100, and the second preset direction is parallel to the width direction of the touch outer layer 100. The first mounting frame 310 is arranged along the second preset direction. In other embodiments, the first preset direction may also be parallel to the width direction of the touch outer layer 100, and the second preset direction may be parallel to the length direction of the touch outer layer 100. The first clamping body 312a is a glass strip, which is usually Z-shaped. In other embodiments, the shape of the first clamping body 312a may be determined according to actual needs. The second mounting surface 311c is a complete surface. The first clamping angle gradually increases along the second preset direction, then remains constant, and then gradually decreases. The reason for setting a larger angle in the middle of the touch outer layer 100 is that the middle part of the touch outer layer 100 is less affected by the clamping force compared to the edge part. At the same time, due to the influence of the gravity of the touch outer layer 100 itself, the middle part of the touch outer layer 100 is less prone to deformation. Therefore, a larger angle is set in the middle of the touch outer layer 100.

[0077] The aforementioned design causes the distance between the touch surface 110 and the first detection path to first decrease, then remain constant, and then increase along the second preset direction. This not only allows the middle portion of the outer touch layer 100 to be closer to the first detection path, further improving the touch experience while ensuring the touch performance of the touch screen, but also helps to disperse stress on the outer touch layer 100, reduce stress concentration, improve the deformation resistance of the outer touch layer 100, and extend the service life of the outer touch layer 100.

[0080] In other embodiments, the first frame 311 may include a plurality of first frame bodies spaced apart along a second preset direction. The surface of the first frame body near the first mounting surface 312b contacts the touch surface 110. The surface of the first frame body near the first mounting surface 312b has a second clamping angle with the first preset direction.

[0081] Reference Figure 6 In one embodiment, the first clamping angle is greater than 0° and less than or equal to 10°; the second clamping angle is greater than 0° and less than or equal to 10°. In a specific embodiment, the angle range of the first clamping angle near the edge of the first frame 311 is 0.5° to 3°, and the angle range of the first clamping angle near the middle of the first frame 311 is 1° to 4°.

[0083] With the cooperation of the first mounting frame 310 and the second mounting frame 320, the touch surface 110 in the first and third embodiments is an overall convex arc surface, and the touch outer layer 100 is an overall convex arc plate; the touch surface 110 in the second and fourth embodiments is a curved surface with convex sides and a flat middle section, and the touch outer layer 100 is a curved plate with convex sides and a flat middle section. Furthermore, to make the first detection path a straight line, the first transmitter 210 and the first receiver 220 in the first touch detection unit are usually adjusted according to the curvature of the first mounting surface 312b and the second mounting surface 311c, so that the first detection path is parallel to the first preset direction and becomes a straight line.

[0084] The aforementioned design not only helps to bring the middle portion of the touch outer layer 100 closer to the first detection path, further improving the touch experience while ensuring the touch screen's touch performance, but also helps to disperse stress on the touch outer layer 100, reducing stress concentration, improving the touch outer layer 100's resistance to deformation, and extending its service life. Furthermore, this design also helps to reduce the manufacturing difficulty and cost of the touch screen.

The first transmitter 210 has two opposing first protrusions 211, and the direction from one of the first protrusions 211 to the other forms an angle with the extension direction of the opening. Two opposing cavity walls within the first mounting cavity 311d are each provided with a first groove, and the two first protrusions 211 are respectively provided in one-to-one correspondence with the two first grooves. The first transmitter 210 is installed in the first mounting cavity 311d by inserting the first protrusions 211 into the corresponding first grooves. Furthermore, the external structure of the first receiver 220 is substantially the same as that of the first transmitter 210.

[0087] Reference Figures 3 to 6 , Figure 10 as well as Figure 11 In one embodiment, the first frame 311 further includes a first filter strip 311e, which is installed in the opening and seals it.

[0090] In this embodiment, both the third mounting frame 330 and the fourth mounting frame 340 are arranged along the first preset direction. This design not only helps to bring the middle portion of the touch outer layer 100 closer to the first detection path, further improving the touch experience while ensuring the touch performance of the touch screen, but also helps to disperse stress on the touch outer layer 100, reduce stress concentration, improve the deformation resistance of the touch outer layer 100, and extend the service life of the touch outer layer 100. Furthermore, this design also helps to reduce the manufacturing difficulty and cost of the touch screen.

The second transmitter is mounted on one of the third mounting frame 330 and the fourth mounting frame 340 and is capable of emitting a second detection light. The second receiver is mounted on the other of the third mounting frame 330 and the fourth mounting frame 340 and is capable of receiving the second detection light. The propagation path of the second detection light between the second transmitter and the second receiver forms a second detection path, which is located on the side of the touch surface 110 away from the back surface 120 and is parallel to the first center line.

[0092] The above design helps reduce the distance between the outer touch layer 100 and the second detection path, so that the touch input component 500, such as the user's finger or stylus, is only detected by the second touch detection unit when it is closer to the outer touch layer 100. This improvement, combined with the improvement that the touch input component 500 is only detected by the first touch detection unit when it is closer to the outer touch layer 100, makes the touch action of the touch input component 500 more consistent with the actual feedback, thus making the touch action of the touch input component 500 more natural and intuitive for writing. By using the mounting part 300 and the outer touch layer 100 in combination, the touch experience of the touch screen is significantly improved while ensuring the touch performance of the touch screen.
