Description

Technical Field

[0001] This invention relates to a touch input device, and more particularly to a touch module. Background Technology

[0002] In known pressure-sensitive touch modules, the pressure sensors inside the module have limited sensing range, and different pressure sensors have different weight measurement ranges. These inherent characteristics of the pressure sensors can easily cause areas on the touch surface of the module to be outside the sensor's sensing range. Furthermore, situations where the pressure is too light or too heavy may result in the sensor failing to detect the pressure, causing that area to lose its pressure-sensing function or become insensitive. Additionally, because touch modules on the market vary in size, the pressure sensors within the module can have inaccurate sensing ranges due to differences in their placement. Moreover, touch modules contain many complex components and circuits; integrating pressure sensors within these complex components and circuits, and ensuring that the pressure sensors operate with minimal interference from other structures and are protected from damage, presents a significant challenge. Summary of the Invention

[0003] To address the problems of prior art, this invention provides a touch module. The touch module of this invention has two pressure sensing elements, each with a different sensing range and a different weight sensing range for detecting the magnitude of pressure applied. By placing the two pressure sensing elements in different areas within the touch module, areas that the other pressure sensing element cannot detect, such as corners, can be compensated for. Furthermore, the sensing ranges of the two elements overlap, with the overlapping area corresponding to areas frequently touched by the user. Moreover, by having the two pressure sensing elements assist each other, the upper and lower limits of the weight measurement range are increased, maximizing the planar coverage of the sensing range and improving the accuracy of weight measurement. This eliminates the sensing dead zones of a single type of sensing element, thereby improving pressure sensing sensitivity. Furthermore, the placement of the pressure sensing elements is tailored to the size and structure of the touch module, improving the overall module's thinness and lightness, while also extending the lifespan of the pressure sensors.

[0103] The touch module 1 of the present invention includes a substrate 10, a touch panel 20, a first pressure sensing element 30, a second pressure sensing element 40, a controller 50, and a vibration element 60.

[0104] The substrate 10 has a surface 11. The touch panel 20 has a circuit layer 21 and a touch layer 22. The touch layer 22 has a first pressure area 221, a second pressure area 222, a third pressure area 223, a plane center 224, and an outer periphery 225. A first pressure sensing element 30 has a first sensing range 31 and can generate a first signal 301. A second pressure sensing element 40 has a second sensing range 41 and can generate a second signal 401. A controller 50 is used to generate a pressure signal P. A vibration element 60 is used to generate vibration to give the touch module 1 a vibration feedback function.

[0105] The substrate 10 and the touch panel 20 are parallel to each other. The touch panel 20 covers the substrate 10, and the circuit layer 21 of the touch panel 20 corresponds to the surface 11 of the substrate 10. The touch layer 22 of the touch panel 20 is located on the opposite side of the circuit layer 21 and is electrically connected to the circuit layer 21. A first pressure sensing element 30 is disposed between the substrate 10 and the touch panel 20 and is electrically connected to the circuit layer 21 of the touch panel 20. Preferably, the first pressure sensing element 30 is disposed within the circuit layer 21 of the touch panel 20. The first sensing range 31 of the pressure sensing element 30 corresponds to the first pressure area 221 of the touch layer 22. A second pressure sensing element 40 is disposed between the substrate 10 and the touch panel 20, and is positioned separately from the first pressure sensing element 30. The second pressure sensing element 40 is electrically connected to the circuit layer 21 of the touch panel 20. Preferably, the second pressure sensing element 40 is disposed within the circuit layer 21 of the touch panel 20. The second sensing range 41 of the second pressure sensing element 40 corresponds to the second pressure area 222 of the touch layer 22. The controller 50 is electrically connected to the first pressure sensing element 30 and the second pressure sensing element 40, and the controller 50 is preferably disposed in the circuit layer 21 of the touch panel 20. The vibration element 60 is disposed between the substrate 10 and the touch panel 20 and is electrically connected to the controller 50.

[0106] When the first pressure area 221 of the touch layer 22 is pressed, the first pressure sensing element 30 generates a first signal 301, and the controller 50 generates a pressure signal P based on the first signal 301. When the second pressure area 222 of the touch layer 22 is pressed, the second pressure sensing element 40 generates a second signal 401, and the controller 50 generates a pressure signal P based on the second signal 401. When the third pressure area 223 of the touch layer 22 is pressed, the first pressure sensing element 30 generates a first signal 301, and the second pressure sensing element 40 also generates a second signal 401. The controller 50 receives both the first signal 301 and the second signal 401 simultaneously, compares the signal strengths of the first signal 301 and the second signal 401, and generates a pressure signal P based on the comparison result.

[0107] In detail, the substrate 10 has multiple support structures 12 and multiple protrusions 13. Each support structure 12 has a spring arm 121 and a spacer 122, and a spacer 122 is correspondingly disposed on a spring arm 121. The touch layer 22 of the touch panel 20 has a planar center 224 and an outer periphery 225. The vibration element 60 has a coil 61 and a magnet 62. The number of first pressure sensing elements 30 is preferably one, but multiple elements can also be provided. This embodiment demonstrates the provision of one first pressure sensing element 30. The second pressure sensing element 40 has multiple pressure sensors 411. Each pressure sensor 411 is spaced apart from each other, and the sensing range of each pressure sensor 411 is interconnected and covers each other to form a second sensing range 41. The following description assigns component labels to the plurality of pressure sensors 411 of the second pressure sensing element 40, namely pressure sensors 411a, 411b, 411c, 411d, 411e, 411f, 411g, 411h, 411i, 411j, 411k, 411l, 411m, and 411n. The plurality of protrusions 13 of the substrate 10 are also assigned component labels, namely protrusions 13a, 13b, 13c, 13d, 13e, 13f, 13g, 13h, 13i, 13j, 13k, 13l, 13m, and 13n.

[0108] The first pressure sensing element 30 senses the deformation of the touchpad 20 after it is pressed, thereby generating a first signal 301. The second pressure sensing element 40 senses the change in distance between the touchpad 20 and the substrate 10, thereby generating a second signal 401. The first pressure sensing element 30 has a wider sensing range, but its structure is more delicate and it is easily interfered with by other components, which can affect its sensitivity or cause damage. Therefore, it needs to be placed at a greater distance from other components. The second pressure sensing element 40 has a narrower sensing range, but it is less susceptible to interference from other component structures, which can affect its sensitivity and lifespan. Therefore, it can be placed in a close area with other component structures. At the same time, the first pressure sensing element 30 can sense a larger weight of pressed pressure, with an optimal weight sensing range of 5 grams to 500 grams; the second pressure sensing element 40 can sense a smaller weight of pressed pressure, with a weight sensing range of 50 grams to 150 grams.

[0109] The first pressure sensing element 30 is preferably a microelectromechanical system (MEMS) pressure sensor, and the second pressure sensing element 40 is preferably a capacitive pressure sensor.

[0110] Multiple support structures 12 and multiple protrusions 13 are disposed on the surface 11 of the substrate 10. The multiple protrusions 13 correspond to multiple pressure sensors 411, and each protrusion 13 corresponds to a single pressure sensor 411. Figure 2 As can be seen, protrusion 13a corresponds to pressure sensor 411a, protrusion 13b corresponds to 411b, and so on.

[0111] Multiple support structures 12 of the substrate 10 are disposed adjacent to multiple pressure sensors 411 of the second pressure sensing element 40. The spring arms 121 of the support structures 12 are formed from the substrate 10, and spacers 122 disposed on the spring arms 121 are used to separate the touchpad 20 from the substrate 10. Furthermore, from... Figure 2 As can be seen, the support structure 12 is positioned between two adjacent pressure sensors 411. This arrangement allows a single support structure 12 to support two pressure sensors 411, separating the pressure sensors 411 from the protrusions 13 of the substrate 10 by a certain distance.

[0112] A vibration element 60 is disposed between the substrate 10 and the touch panel 20, and its position corresponds to the second pressure area 222 of the touch layer 22. The coil 61 of the vibration element 60 is disposed on the circuit layer 21 of the touch panel 20 and adjacent to the second pressure sensing element 40. The magnet 62 of the vibration element 60 is disposed on the surface 11 of the substrate 10, and the coil 61 corresponds to the magnet 62. When the coil 61 is energized, it senses the magnet 62 and generates vibration. The vibration element 60 is positioned adjacent to the second pressure sensing element 40, which minimizes interference with pressure sensing or potential damage to the sensor.

[0114] Depend on Figure 3 As shown, in the touch layer 22 of the touch panel 20, the first touch area 221 is located at the center 224 of the plane of the touch layer 22, the second touch area 222 is located at the outer periphery 225 of the touch layer 22, and the third touch area 223 of the touch layer 22 is located between the first touch area 221 and the second touch area 222.

[0115] Figure 4As shown, the first pressure sensing element 30 is positioned corresponding to the center 224 of the touch layer 22. The second pressure sensing element 40 is positioned corresponding to the outer periphery 225 of the touch layer 22, and a plurality of pressure sensors 411a to 411n of the second pressure sensing element 40 are arranged around the outer periphery 225 of the touch layer 22. The first sensing range 31 of the first pressure sensing element 30 extends from the center 224 of the touch layer 22 towards the outer periphery 225. Due to the limitation of the sensing range, the maximum sensing range 31 of the first pressure sensing element 30 can sense and cover is located at a first sensing range boundary 311. The second sensing range 41 of the second pressure sensing element 40 extends from the outer periphery 225 of the touch layer 22 towards the center 224 of the touch layer 22. Also due to the limitation of the sensing range, the maximum sensing range 41 of the second pressure sensing element 40 can sense and cover is located at a second sensing range boundary 412. Areas not covered by the first sensing range 31 are covered by the second sensing range 41, and similarly, areas not covered by the second sensing range 41 are covered by the first sensing range 31.

[0116] Meanwhile, since the first pressure sensing element 30 is positioned corresponding to the first touch area 221 of the touch layer 22 that users frequently press, the optimal weight sensing range for the first pressure sensing element 30 is a pressing pressure of 5 grams to 500 grams, which allows for more precise sensing of the user's pressing action and the amount of pressing force. The second pressure sensing element 40 is positioned corresponding to the second touch area 222 of the touch layer 22 that users do not frequently use or press. Therefore, the second pressure sensing element 40 is positioned here, and its weight sensing range is a pressing pressure of 50 grams to 150 grams. Users need to apply a larger pressing force to sense it, and it cannot sense excessively heavy pressing forces, in order to avoid accidental touches by users or misjudgments caused by the pressure of other heavy objects.

[0117] An overlapping sensing range D is formed between the first sensing range 31 of the first pressure sensing element 30 and the second sensing range 41 of the second pressure sensing element 40. The overlapping sensing range D corresponds to the third touch area 223 of the touch layer 22. The third touch area 223 is precisely the area of ​​the touchpad 20 that is most easily touched during use. Therefore, having two pressure sensors operating in this area can improve sensing accuracy and lifespan. If one pressure sensor fails, the other pressure sensor will provide support. Furthermore, since both the first pressure sensing element 30 and the second pressure sensing element 40 can function in the third touch area 223, the weight sensing range for sensing the amount of pressure applied is between 5 grams and 500 grams, allowing sensing of both light and heavy pressure from the user.

[0118] Please see below. Figure 5 , Figure 6A, Figure 6B , Figure 7A , Figure 7B , Figure 8A , Figure 8B as well as Figure 8C .

[0119] Figure 5 The touchpad 20 displays the touch area and the sensing range of the pressure sensing element. Three different touch positions are displayed on the touchpad 20. These touch positions are not generated simultaneously, but rather by the user pressing different positions individually. The three different touch positions are a first touch position T1, a second touch position T2, and a third touch position T3.

[0120] This section explains the sensing and signal processing method of the second pressure sensing element 40, in conjunction with reference. Figure 6A , Figure 6B and Figure 8A . Figure 6A When the touchpad 20 is not pressed, a first distance S1 is maintained between the pressure sensor 411a of the second pressure sensing element 40 on the touchpad 20 and the protrusion 13a of the substrate 10. Figure 6B When the touchpad 20 is pressed, when the user touches and presses the touchpad 20 to form a touch position T3, the user's touch pressure causes the touchpad 20 to move closer to the substrate 10. Since the touch position T3 is located in the second touch area 222 and is within the second sensing range 41, the distance between the pressure sensor 411a and the protrusion 13a near the touch position T3 changes due to the user's touch pressure, and the distance decreases from the first distance S1 to a second distance S2. Figure 8A As shown, the second pressure sensing element 40 senses a change in distance and generates a second signal 401. The controller 50 generates a pressure signal P based on the second signal 401, and the controller 50 controls the vibration element 60 to vibrate.

[0121] The sensing and signal processing method of the first pressure sensing element 30, such as Figure 7A , Figure 7B and Figure 8A . Figure 7A When the touchpad 20 is not pressed, the touchpad 20 will not deform, so the first pressure sensing element 30 provided on the touchpad 20 will not generate a signal. Figure 7B The state of the touchpad 20 when it is pressed: When the user touches and presses the touchpad 20 to form a touch position T1, since the touch position T1 is located in the first touch area 221 and is within the first sensing range 31, the touch pressure causes the touchpad 20 to produce a slight bending deformation. The first pressure sensing element 30 senses the deformation of the touchpad 20 and generates a first signal 301. Figure 8BAs shown, the controller 50 generates a pressure signal P according to the first signal 301, and the controller 50 controls the vibration element 60 to generate vibration.

[0122] The sensing and signal processing method for the second touch position T2 will be further explained. The second touch position T2 is located in the third touch area 223, which is within the overlapping sensing range D formed by the overlap of the first sensing range 31 and the second sensing range 41. Therefore, the touch pressure at the second touch position T2 will be sensed by both the first pressure sensing element 30 and the second pressure sensing element 40. According to the aforementioned method, the touch panel 20 moves closer to the substrate 10 and the touch panel 20 undergoes a slight bending deformation, causing the second pressure sensing element 40 to generate a second signal 401 and the first pressure sensing element 30 to generate a first signal 301. Figure 8C As shown, at this time, the controller 50 will simultaneously receive the first signal 301 and the second signal 401, and the controller 50 will compare the signal strength of the two signals, the first signal 301 and the second signal 401. The controller 50 will generate a pressure signal P based on the signal with stronger signal strength, and the controller 50 will control the vibration element 60 to vibrate.

[0123] The embodiment of the touch module 1 of the present invention uses one or more, preferably two or more, pressure sensing elements to sense pressure in the touch area of ​​the same touch module. The main technical focus is on combining two pressure sensing functions with different planar sensing ranges and different weight sensing ranges within the same touch area, achieving joint operation and mutual assistance, so that the function not achieved by one sensing element is supplemented by another. Alternatively, when using the same pressure sensing element, multiple identical pressure sensing elements can be arranged in different positions and combinations to achieve pressure sensing functions for detecting different planar sensing ranges and different weight sensing ranges, without departing from the intended effect and technical spirit of the present invention.

[0124] The above description is only a preferred embodiment of the present invention. Any equivalent changes or modifications made without departing from the spirit disclosed in the present invention should be included within the scope of the present invention.
