Description

Technical Field

[0001] The present invention relates to the technical field of touch screen production, and in particular to a physical touch simulation device, a touch screen and a storage medium. Background Art

[0002] At present, entertainment cockpits have become a major selling point for the intelligence of domestic automobile products. More and more display screens in the cockpit are used to display different functional operations in the car. Based on cost and interior style considerations, most car companies have cancelled physical buttons and integrated the button functions on the display screen.

[0003] As entertainment display screens integrate more and more functions, most functions require a long time to be triggered, so car companies also place some commonly used functions on the lower side of the display screen. However, even if quick operations are set on the display screen, the driver still cannot operate as quickly as traditional physical buttons while the vehicle is driving, and the driver's field of vision stays for a long time, affecting driving safety.

[0004] In order to facilitate the realization of functions, most entertainment cockpit solutions on the market also integrate voice wake-up and voice operation functions. However, voice operation has the problem of unclear content recognition, which affects the user experience of the driver and other people in the car. Summary of the invention

[0005] The present invention provides a physical touch simulation device, a touch screen and a storage medium, which solve the technical problems that the existing display screen function area cannot be blindly operated, is prone to accidental touches, requires the driver's line of sight assistance but affects driving safety.

[0006] In order to solve the above technical problems, the present invention provides a physical touch simulation device, comprising:

[0007] A first diaphragm module (1) and a second diaphragm module (2);

[0008] and a touch simulation module (3), the touch simulation module (3) comprising a trigger detection component and at least one set of simulation deformation components:

[0009] At least one group of the simulated deformation components is arranged between the first diaphragm module (1) and the second diaphragm module (2), and overlaps with the corresponding virtual key space in the touch display module (4); the second diaphragm module (2) covers the touch display module (4); the trigger detection component is electrically connected to the touch display module (4), and the trigger detection component is also electrically connected to the simulated deformation component; the simulated deformation component is used to deform and protrude under the drive of the trigger detection component to simulate the physical touch.

[0010] The basic solution inserts a simulated deformation component between a first diaphragm module (1) and a second diaphragm module (2), connects to a touch display module (4) via a trigger detection component, and uses the touch detection function of the touch screen itself to detect the user's touch operation, thereby driving the simulated deformation component to deform and bulge to simulate the touch of a physical key, thereby achieving the same touch as a physical key on the touch display screen, improving the driver's blind operation efficiency, avoiding driver distraction, and increasing operation safety.

[0011] In a further embodiment, the simulated deformation component includes a memory material (31), and the memory material (31) is a slender linear structure, with its two ends electrically connected to the trigger detection component and the middle portion extending in a zigzag manner to form a transparent touch surface (32) arranged evenly at intervals in a matrix shape; the transparent touch surface (32) is placed on the corresponding virtual key in the touch display module (4), and is covered with the first membrane module (1).

[0012] The present solution uses a plurality of memory materials (31) arranged at even intervals to form a transparent touch surface (32), and makes it overlap with virtual keys (e.g., shortcut keys with different functions) on a touch display module (4). On the one hand, the memory material (31) formed by zigzag extension can assist in realizing the transparency of the transparent touch surface (32); on the other hand, the two ends of the thin-line memory material (31) are connected to a power source to realize electrical stimulation deformation, and a single-layer transparent touch surface supports the touch area to cover the virtual keys to provide a significant physical touch. The structure is thinner and lighter, and the optical display experience of the display screen can be not sacrificed, and the transparent and hidden functions can be realized in the full-screen state.

[0013] In a further embodiment, the line thickness of the memory material (31) is in the range of [0.05 mm, 0.1 mm].

[0014] This solution takes into account that the pupil of the human eye cannot distinguish objects below the visual limit size, and sets the size range of the memory material (31) to 0.05 mm to 0.1 mm (line thickness). Since the wiring spacing is the visual limit size of the human eye, the wiring traces cannot be seen on the surface of the display screen, which does not affect the normal display function of the display screen, and provides a better user experience.

[0015] In a further embodiment, the memory material (31) is attached to the back of the first diaphragm module (1) through an etching process; when the trigger detection component is triggered, the memory material (31) is driven to deform away from the second diaphragm module (2), thereby driving the first diaphragm module (1), so that the transparent touch surface protrudes upward to simulate the physical touch of a button.

[0016] In a further embodiment, the memory material (31) is attached to the front side of the second diaphragm module (2) through an etching process; when the trigger detection component is triggered, the memory material (31) is driven to deform upward to support the first diaphragm module (1), so that the transparent touch surface protrudes upward to simulate the physical touch of a key.

[0017] In this solution, the memory material (31) is disposed on the back side of the first diaphragm module (1) and the front side of the second diaphragm module (2) by etching, thereby eliminating the need to reserve deformation space for the memory material (31) to deform, thereby providing users with a transparent, unobstructed touch screen viewing experience.

[0018] In a further embodiment, the trigger detection component includes a controller and an FFC cable, the controller is electrically connected to the touch display module (4), and the controller is also electrically connected to the simulation deformation component through the FFC cable.

[0019] In a further embodiment, the first membrane module (1) comprises an optical film; the second membrane module (2) comprises an adhesive-backed membrane and an adhesive layer, and the adhesive-backed membrane is adhered to the touch display module (4) through the adhesive layer; the first membrane module (1) is adhered to the front of the second membrane module (2) through an optical substrate-free adhesive tape.

[0020] The present invention also provides a touch screen, comprising a physical touch simulation device as described above, and a touch display module (4), wherein the touch display module (4) comprises a touch detection circuit, and the touch detection circuit is electrically connected to a trigger detection component in the touch simulation device;

[0021] The touch detection circuit acquires the touch signal in real time for identification, and determines whether to trigger the quick operation according to the touch signal, and if so, proceeds to the next step;

[0022] The touch detection circuit drives the controller of the physical touch simulation device to output a start signal, thereby controlling all the transparent touch surfaces (32) in the simulation deformation component to deform and protrude into a working state;

[0023] The touch detection circuit obtains the touch signal generated by the user's touch operation, identifies the virtual key corresponding to the touch signal, determines the user's intention and executes it. The touch screen provided by this basic solution electrically connects the touch detection circuit in the touch display module (4) with the trigger detection component in the touch simulation device, directly uses its original circuit structure for detection, and effectively reduces the cost of function implementation while realizing the physical key touch simulation.

[0024] In a further embodiment, the touch display module further includes:

[0025] a display configured to display an image;

[0026] a processor coupled to the display and the tactile simulation device; and

[0027] A memory device includes instructions executable by the processor to cause the processor to detect motion in one or more directions across a surface of the display.

[0036] The following specifically illustrates the implementation mode of the present invention in conjunction with the accompanying drawings. The embodiments are provided for illustrative purposes only and cannot be understood as limiting the present invention. The accompanying drawings are provided for reference and illustration only and do not constitute a limitation on the scope of patent protection of the present invention, because many changes can be made to the present invention without departing from the spirit and scope of the present invention.

[0037] Example 1

[0038] An embodiment of the present invention provides a physical touch simulation device, such as Figure 1 to Figure 3 As shown, in this embodiment, it includes:

[0039] A first diaphragm module 1, a second diaphragm module 2;

[0040] and a touch simulation module 3, wherein the touch simulation module 3 includes a trigger detection component and at least one set of simulation deformation components:

[0041] At least one group of the simulated deformation components is arranged between the first diaphragm module 1 and the second diaphragm module 2, and overlaps with the corresponding virtual key space in the touch display module 4; the second diaphragm module 2 covers the touch display module 4; the trigger detection component is electrically connected to the touch display module 4, and the trigger detection component is also electrically connected to the simulated deformation component; the simulated deformation component is used to deform and protrude under the drive of the trigger detection component to simulate the physical touch.

[0042] In this embodiment, the simulated deformation component includes a memory material 31, which is a slender linear structure, with its two ends electrically connected to the trigger detection component and the middle part extending in a zigzag manner to form a transparent touch surface 32 evenly spaced in a matrix shape; the transparent touch surface 32 is placed on the corresponding virtual button in the touch display module 4, and is covered with the first membrane module 1.

[0043] The memory material 31 is preferably a shape memory alloy (memory metal). The shape memory alloy realizes electrical stimulation of deformation, and drives the memory metal to deform or restore its original shape with a changing current output. In other embodiments, the memory material 31 can also be set as a shape memory plastic as required. The shape memory plastic can utilize its thermosensitive properties to perform temperature control to drive the deformation of the shape memory plastic.

[0044] The present solution uses a number of memory materials 31 arranged at even intervals to form a transparent touch surface 32, and makes it overlap with the virtual keys (such as shortcut keys with different functions) on the touch display module 4. On the one hand, the memory material 31 formed by zigzag extension can help realize the transparency of the transparent touch surface 32; on the other hand, the two ends of the thin linear memory material 31 are connected to a power source to realize electrical stimulation deformation, and a single-layer transparent touch surface supports the touch area to cover the virtual keys to provide a significant physical touch. The structure is thinner and lighter, so it will not destroy the interlayer structure of the membrane to form a bulge that is difficult to eliminate, and thus can achieve the functions of transparency and hiding in full screen state without sacrificing the optical display experience of the display screen.

[0045] In this embodiment, the memory material 31 is attached to the back of the first diaphragm module 1 through an etching process; when the trigger detection component is triggered, the memory material 31 is driven to deform away from the second diaphragm module 2, thereby driving the first diaphragm module 1, so that the transparent touch surface protrudes upward to simulate the physical touch of a button.

[0046] Alternatively, in other embodiments, the memory material 31 is attached to the front side of the second diaphragm module 2 through an etching process; when the trigger detection component is triggered, the memory material 31 is driven to deform upward to support the first diaphragm module 1, so that the transparent touch surface protrudes upward to simulate the physical touch of a button.

[0047] In this embodiment, the memory material 31 is disposed on the back side of the first diaphragm module 1 and the front side of the second diaphragm module 2 by etching, so that there is no need to reserve deformation space for the memory material 31 to deform, thereby providing users with a transparent and unobstructed touch screen viewing experience.

[0048] In this embodiment, the line thickness of the memory material 31 ranges from 0.05 mm to 0.1 mm.

[0049] For objects with a diameter of 2mm-9mm, the human eye's resolution limit is about 100 microns at a clear vision distance of 25cm. For objects with physical dimensions below the clear vision limit, the human eye cannot distinguish them.

[0050] In this embodiment, considering that the human pupil cannot distinguish objects below the limit size of clear vision, the size range of the memory material 31 is set to 0.05mm~0.1mm (line thickness). Since the wiring line thickness is within the limit size of clear vision of the human eye, its routing traces cannot be seen on the surface of the display screen, which does not affect the normal display function of the display screen and provides a better user experience.

[0051] In this embodiment, the trigger detection component includes a controller and an FFC cable. The controller is electrically connected to the touch display module 4 . The controller is also electrically connected to the simulation deformation component through the FFC cable.

[0052] When a human finger touches a specified position on the display screen, the touch display module 4 (such as a touch IC) will obtain the position of the human finger and transmit the position information to the controller through an electronic circuit, and transmit the corresponding signal to the simulated deformation component (i.e., the memory material 31 with deformation function) in the form of but not limited to the FFC cable, and the execution deformation of the simulated deformation component realizes the touch of the physical button.

[0053] In this embodiment, the first membrane module 1 includes an optical film; the second membrane module 2 includes a back-adhesive membrane and a back-adhesive layer, and the back-adhesive membrane is attached to the touch display module 4 through the back-adhesive layer; the first membrane module 1 is attached to the front of the second membrane module 2 through an optical substrate-free tape.

[0054] Among them, in addition to the protection function and optical function, the first diaphragm module 1 also has the function of bearing the deformation of the simulated deformation component, so that when the simulated deformation component is deformed, the first diaphragm module 1 will deform at the specified position; when the simulated deformation component is not deformed, the first diaphragm module 1 is in a flat state.

[0055] Optical non-substrate tape is a special type of tape specially used for optical applications, such as the bonding of various optical films for display panels. It has high transparency, low haze, excellent weather resistance and moisture and heat resistance.

[0056] The beneficial effects of the embodiments of the present invention include: inserting a simulation deformation component between the first diaphragm module 1 and the second diaphragm module 2, connecting the touch display module 4 through a trigger detection component, and using the touch detection function of the touch screen itself to detect the user's touch operation, thereby driving the simulation deformation component to deform and bulge to simulate the touch of a physical button, thereby achieving the same touch as a physical button on the touch display screen, improving the driver's blind operation efficiency, avoiding driver distraction, and increasing operation safety.

[0057] Example 2

[0058] The present invention also provides a touch screen, see Figure 4 , Figure 5 , including a physical touch simulation device as provided in the above-mentioned embodiment 1, and a touch display module 4, wherein the touch display module 4 includes a touch detection circuit, and the touch detection circuit is electrically connected to the trigger detection component in the touch simulation device.

[0059] In this embodiment, the touch display module further includes:

[0060] a display configured to display an image;

[0061] a processor coupled to the display and the tactile simulation device; and

[0062] A memory device includes instructions executable by the processor to cause the processor to detect motion in one or more directions across a surface of the display.

[0063] Wherein, the touch detection circuit includes a capacitive detection circuit.

[0064] The capacitive detection circuit acquires the touch signal in real time and feeds it back to the processor for identification. The processor determines whether to trigger the quick operation according to the touch signal, and if so, proceeds to the next step;

[0065] The processor drives the controller of the physical touch simulation device to output a start signal to control all the transparent touch surfaces 32 in the simulation deformation assembly to deform and protrude into a working state;

[0066] The capacitive detection circuit obtains the touch signal generated by the user's touch operation and feeds it back to the processor to identify the virtual key corresponding to the touch signal, determine the user's intention and execute it. The touch working principle is:

[0067] A shortcut key (virtual key) for quick operation or a wake-up mechanism is set in the panel area corresponding to the touch screen. When a person's finger touches a specified position on the display screen (that is, when the driver performs an interface operation with a shortcut operation on the touch screen) or performs a corresponding wake-up touch operation (such as double-clicking or sliding), the touch detection circuit detects the operation signal and feeds back to the controller. The controller drives all transparent touch surfaces 32 in the simulated deformation component to enter a working state (deformation protrusions). The driver quickly finds the key position and implements the operation through the concave and convex feel of the touch screen surface (for example, setting the shortcut key in this area requires click triggering or double-click triggering, thereby simulating the press control of the physical key to avoid accidental touch).

[0068] When the display screen is in a full-screen display screen without quick operation, the simulated deformation component is in a non-working state (no deformation protrusion), and the simulated deformation component has no blocking effect on the displayed content.

[0069] See also Figure 6 , comparing the display interface when the simulated deformation component is in a non-working state (no deformation protrusion) and the simulated deformation component is in a working state (deformation protrusion), at an inclined angle, it can be observed that there is a protrusion on the screen of the display interface when the simulated deformation component is in a working state, and the screen of the display interface is smooth and unobstructed when the simulated deformation component is in a non-working state.

[0070] The touch screen provided in the embodiment of the present invention electrically connects the touch detection circuit in the touch display module 4 with the trigger detection component in the touch simulation device, and directly uses its original circuit structure for detection, thereby effectively reducing the cost of function implementation while realizing the touch simulation of physical buttons.

[0072] The embodiment of the present invention further provides a storage medium, on which a computer program is stored, and the computer program is used to be loaded by a physical touch simulation device as described in the above embodiment 1 to perform touch simulation. The storage medium can be a disk, an optical disk, a read-only memory (ROM) or a random access memory (RAM), etc.

[0073] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
