[0026] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0027] This application provides a display module, which can be used in electronic devices such as vehicle screen modules, mobile phone display modules, and tablet computer display modules. This display module generates different vibration sensations through a vibrating body, providing a customized vibration feedback experience. Reference Figure 1 and Figure 2 This application provides a display module, which includes: The housing 1 and the control board 2 are fixed inside the housing 1; The screen 3 and at least one vibrator 4 are provided, with the screen 3 located on the upper part of the control panel 2 and the vibrator 4 located between the control panel 2 and the screen 3. The vibrator 4 includes a piezoelectric sheet 41 and a conical vibrating part 42. The outer ring of the conical vibrating part 42 is connected to the piezoelectric sheet 41, and the middle part of the conical vibrating part 42 can stop the screen 3. The outer ring of the conical vibrating part 42 can be the large end of the conical vibrating part 42, and the middle part of the conical vibrating part 42 can be the small end of the conical vibrating part 42.

[0028] In the above embodiment, the housing 1 provides structural support and protection for the entire display module. With the control board 2 fixed inside the housing 1, the housing 1 provides a stable mounting base for the control board 2 to control the operation of the entire display module, ensuring that all electronic components on the control board 2 can work normally and realize the various functions of the display module.

[0029] See Figure 1 Screen 3 serves as the main interface for user interaction with the electronic device. It is positioned above the control panel 2 to facilitate the display of various information and images, as well as the reception of user touch operations. A vibrator 4 is positioned between the control panel 2 and the screen 3. Under the control of the control panel 2, the vibrator 4 generates vibrations and transmits these vibrations to the screen 3, thus providing tactile vibration feedback to the user when the screen 3 is touched.

[0030] See Figure 2 and Figure 3 The piezoelectric element 41 can be electrically connected to the control board 2. Under the control of the control board 2, when an electrical signal is applied to the piezoelectric element 41, it can cause the piezoelectric element 41 to undergo mechanical deformation, providing a power source for the vibration of the entire vibrating body 4. The outer ring of the conical vibrating part 42 is connected to the piezoelectric element 41, so that the lateral (plane direction of the piezoelectric element 41) deformation generated by the piezoelectric element 41 can be effectively transmitted to the conical vibrating part 42 and realize the longitudinal (axial direction of the conical vibrating part 42) deformation of the conical vibrating part 42. For example, when the piezoelectric element 41 contracts laterally, it can drive the outer ring of the conical vibrating part 42 to shrink, thereby increasing the axial height of the conical vibrating part 42 and thus increasing the height of the screen 3. Or, when the piezoelectric element 41 expands laterally, it can drive the outer ring of the conical vibrating part 42 to enlarge, thereby decreasing the axial height of the conical vibrating part 42 and thus lowering the height of the screen 3. While ensuring vibration transmission efficiency, the screen 3 can achieve reciprocating vibration corresponding to touch.

[0031] In one embodiment, the middle portion of the conical vibrating part 42 can be hollow, allowing the inner ring of the conical vibrating part 42 to be connected to the screen 3 and used to stop the screen 3, thus providing effective vibration to the screen 3 through the annular conical vibrating part 42. In another embodiment, the middle portion of the conical vibrating part 42 may also have a stopping platform, which can be connected to the screen 3 and used to stop the screen 3, thereby improving the vibration efficiency of the screen 3.

[0032] In some embodiments, the conical vibration part 42 can be a conical metal sheet such as a titanium sheet, aluminum sheet or copper sheet, which ensures the structural strength of the conical vibration part 42 and can provide effective vibration to the screen 3 through the deformation of the metal sheet.

[0033] In some embodiments, the display module includes multiple vibrators 4, which are distributed between the control panel 2 and the screen 3. The multiple vibrators 4 are spaced apart and cooperate with each other to produce stronger and richer vibration effects. Compared with a single vibrator, multiple vibrators can emit vibrations simultaneously from different positions and angles, forming a more three-dimensional and layered vibration feedback, allowing users to more clearly perceive the vibration information corresponding to the operation, and improving the tactile experience when users interact with the display module.

[0034] The display module provided in this application embodiment includes a housing 1 and a control board 2, with the control board 2 fixed inside the housing 1; a screen 3 and at least one vibrator 4, with the screen 3 disposed on the upper part of the control board 2 and the vibrator 4 disposed between the control board 2 and the screen 3; the vibrator 4 includes a piezoelectric sheet 41 and a conical vibrating part 42, with the outer ring of the conical vibrating part 42 connected to the piezoelectric sheet 41, and the middle part of the conical vibrating part 42 able to stop the screen 3, the piezoelectric sheet 41 driving the conical vibrating part 42 to deform, thereby providing the screen 3 with high-intensity vibration feedback corresponding to the touch operation, which can give the user sufficient and clear tactile signals, enabling the user to accurately judge the operation status and improve the intuitiveness and accuracy of the interaction.

[0035] Moreover, the vibrator 4 uses a structure that combines a piezoelectric sheet 41 and a conical vibrating part 42, so there is no electromagnetic interference. Furthermore, the response of the deformation vibration is fast, and it can provide clear vibration feedback.

[0036] In one embodiment, the vibrator 4 adopts a D31 lateral displacement type vibration mode. A piezoelectric sheet 41, such as a piezoelectric ceramic sheet, is given an excitation voltage at its resonant frequency. The piezoelectric sheet 41 contracts horizontally. At this time, the conical vibrating part 42 attached to the surface of the piezoelectric sheet 41 converges towards the center along with its edge. The center of the conical vibrating part 42 undergoes a longitudinal upward deformation. Since the lower end of the vibrator 4 is fixed, the entire vibrator 4 will undergo an upward displacement. When the piezoelectric sheet 41 contracts to its maximum extent, the entire vibrator 4 reaches its maximum displacement point, achieving the upward stop of the screen 3. Similarly, when the piezoelectric sheet 41 stretches horizontally, the center of the conical vibrating part 42 undergoes a longitudinal downward deformation. When the piezoelectric sheet 41 stretches to its maximum extent, the entire vibrator 4 reaches its maximum reverse displacement point, achieving the downward vibration of the screen 3. The vibrator 4 thus achieves the conversion of horizontal (lateral) vibration to vertical (longitudinal) vibration, thereby generating a more directional vibration feedback.

[0037] In some embodiments, see Figure 3 and Figure 4 The conical vibration section 42 includes a first vibration section 421 and a second vibration section 422, both of which are conical. The outer rings of the first vibration section 421 and the second vibration section 422 are respectively connected to the two sides of the piezoelectric sheet 41. The middle part of the first vibration section 421 is connected to the control board 2, and the middle part of the second vibration section 422 can stop the top screen 3.

[0038] In the above embodiment, when the piezoelectric sheet 41 undergoes lateral deformation, it can simultaneously and uniformly transmit the deformation to the first vibration part 421 and the second vibration part 422. Simultaneous force on both sides of the piezoelectric sheet 41 ensures the balance of vibration transmission, avoiding vibration deviation or energy loss caused by uneven force on one side, thus improving the efficiency and stability of vibration transmission. This ensures that the entire vibrating body 4 can more effectively convert electrical energy into mechanical vibration energy. Furthermore, the deformation coordination of the first vibration part 421 and the second vibration part 422 on both sides of the piezoelectric sheet 41 increases the vibration amplitude of the vibrating body 4 and increases the intensity of the vibration feedback from the screen 3 driven by the vibrating body 4.

[0039] See Figure 4 , Figure 6 and Figure 7 The first vibration unit 421 is connected to the control board 2, providing stable support and a fixed point for the entire vibrating body 4, ensuring that the vibrating body 4 will not shake or shift during operation, and guaranteeing the accuracy and consistency of vibration feedback. Furthermore, the deformation of the first vibration unit 421 increases the vibration amplitude of the vibrating body 4. Simultaneously, the middle part of the second vibration unit 422 directly acts on the screen 3. The conical structure of the second vibration unit 422 concentrates vibration energy, more effectively transmitting the vibration generated by the piezoelectric sheet 41 and the vibration transmitted from the first vibration unit 421 to the screen 3, enhancing the vibration feedback intensity of the screen 3, reducing energy loss during transmission, and providing the user with sufficient and clear tactile signals, enabling the user to accurately judge the operating status and improving the intuitiveness and accuracy of the interaction.

[0040] In one embodiment, the first vibrating part 421 and the second vibrating part 422 are symmetrically arranged on both sides of the piezoelectric sheet 41.

[0041] In the above embodiments, the symmetrical arrangement ensures that the forces generated by the first vibration part 421 and the second vibration part 422 during vibration are balanced, effectively reducing overall device shaking or additional noise caused by vibration imbalance, and providing more stable and comfortable tactile feedback. Furthermore, the symmetrical structure formed by the first vibration part 421 and the second vibration part 422 ensures the superposition of vibration amplitudes of the two vibration parts during vibration, resulting in a greater intensity of vibration feedback received by the screen 3.

[0042] In some embodiments, see Figure 2 and Figure 5The display module also includes a support plate 5, which is located on the side of the screen 3 near the control plate 2. The middle part of the conical vibrating part 42 is connected to the support plate 5.

[0043] In the above embodiments, the support plate 5 provides support for the screen 3. When the screen 3 is subjected to external forces, it can effectively disperse stress, reduce the risk of deformation or damage to the screen 3 due to uneven stress, and ensure the stability and reliability of the display effect of the screen 3. Moreover, when the screen 3 vibrates, it can ensure that the vibration of the screen 3 is consistent, and achieve the purpose of adjustable sound volume of the screen 3.

[0044] See Figure 7 The middle part of the conical vibrating part 42 is connected to the support plate 5, providing a more stable fixing point for the vibrator 4. Compared with the vibrator 4 being directly connected to the screen 3, the support plate 5 can better withstand the reaction force generated by the vibrator 4 during operation, reduce the shaking and displacement of the vibrator 4, ensure that the vibrator 4 is always in an accurate working position, and improve the accuracy and consistency of vibration feedback.

[0045] In some embodiments, see Figure 2 and Figure 3 The control plate 2 is provided with a guide assembly hole 21, and the support plate 5 is provided with a guide rod 51, which passes through the guide assembly hole 21.

[0046] In the above embodiments, the guide assembly hole 21 provides a precise positioning reference for the assembly of the support plate 5 and the control plate 2. When assembling the display module, by aligning the corresponding components on the support plate 5 with the guide assembly hole 21, the support plate 5 can be quickly and accurately installed into the designated position of the control plate 2, ensuring the relative positional accuracy between the two and avoiding the impact of assembly deviations on the performance and stability of the display module.

[0047] In the vibration feedback system of the display module, the support plate 5 can stably transmit the vibration generated by the conical vibrating part 42 to the screen 3. The structure of the guide rod 51 passing through the guide assembly hole 21 restricts the support plate 5 to vibrate only in the vertical direction, ensuring the stability of the connection between the support plate 5 and the control plate 2, reducing vibration energy loss and uneven transmission caused by the shaking of the support plate 5, and enabling the vibration to be transmitted from the vibrating body to the screen more efficiently and stably, providing users with clear and accurate tactile feedback, and improving the intuitiveness and accuracy of the interaction.

[0048] In some embodiments, see Figure 3 The display module also includes a linear bearing 6, which is disposed in the guide assembly hole 21, and the guide rod 51 is connected to the linear bearing 6.

[0049] In the above embodiment, the linear bearing 6 and the guide mounting hole 21 on the control plate 2 can be interference-fitted. The guide rod 51 is connected to the linear bearing 6. The linear bearing 6 has the characteristic of low friction coefficient. When the guide rod 51 moves in the linear bearing 6, it can significantly reduce the frictional resistance between the two and ensure the stable and effective vibration of the support plate 5 in the vertical direction.

[0050] In some embodiments, see Figure 2 and Figure 5 The support plate 5 includes a support frame 52 and a hollow area 53 located in the support frame 52. The support frame 52 is connected to the side of the screen 3 near the control plate 2. The hollow area 53 is used to avoid electronic devices on the screen 3.

[0051] In the above embodiment, connecting the support frame 52 to the side of the screen 3 near the control board 2 fully utilizes the internal space of the display module, making the overall structure more compact and ensuring the rigidity of the screen 3. The screen 3 integrates electronic components such as driver chips, capacitors, resistors, and connecting lines. The design of the cutout area 53 provides clearance for these electronic components, preventing interference between the support board 5 and the electronic components, ensuring normal installation and operation of the electronic components, and contributing to improved integration and reliability of the display module.

[0052] In some embodiments, see Figure 1 and Figure 2 The display module also includes a protective frame 7. The screen 3 includes a screen control board 31 and a display screen 32. The screen control board 31 is located on the upper part of the control board 2, and the display screen 32 is attached to the side of the screen control board 31 away from the control board 2. The protective frame 7 is located around the display screen 32.

[0053] In the above embodiment, the screen control board 31 of screen 3 can process and control the display signals, power management, touch signal processing, and other functions of the display screen 32, and convert and process the signals from the control board 2 before outputting them to the display screen 32, enabling the display screen 32 to correctly display images and text. Since the screen control board 31 and the display screen 32 are relatively independent components, as display technology continues to develop and update, the screen control board 31 or the display screen 32 can be easily upgraded or replaced individually.

[0054] See Figure 2 By positioning the control board 31 on top of the control board 2, the signal transmission line between the control board 31 and the control board 2 is shortened. This helps reduce signal attenuation and interference during transmission, improving the stability and reliability of signal transmission. This ensures that the display screen 32 can accurately and promptly receive control signals and achieve normal display functions. Furthermore, the close fit between the display screen 32 and the control board 31 reduces the air gap between them, resulting in clearer and sharper image display and enhancing the user's visual experience.

[0055] See Figure 1 The protective frame 7 is located around the display screen 32, providing effective physical protection for the display screen 32. During daily use, transportation, or installation, the display screen 32 may be subjected to external forces such as collisions and scratches. The protective frame 7 can prevent the display screen 32 from being damaged by direct impact, thereby extending the service life of the display module.

[0056] In one specific embodiment, the screen 3 is made up of the display screen 32 and the screen control board 31, which are attached together by double-sided adhesive. The four corners of the screen control board 31 are connected to the support plate 5 by screws to ensure the stability of the screen 3. The display screen 32 can be embedded in the opening of the protective frame 7 to facilitate the display of the display module.

[0057] In some embodiments, see Figure 2 and Figure 3 A support block 22 is detachably mounted on the control panel 2, and the vibrator 4 is connected to the support block 22.

[0058] In the above embodiment, the vibrator 4 can be attached to the support block 22 using a coupling agent to ensure the stability of the vibrator 4. The support block 22 is detachably connected to the control board 2. When it is necessary to replace a different type of vibrator 4, only the support block 22 needs to be removed and reinstalled. In addition, if the vibrator 4 malfunctions, since the support block 22 is detachable, technicians can easily remove the support block 22 from the control board 2, and then perform individual inspection, repair or replacement of the vibrator 4, thereby improving maintenance efficiency and reducing maintenance costs.

[0059] In some embodiments, see Figure 2 The display module also includes a circuit board 8, which is fixed inside the housing 1. A power port 11 on the housing 1 is connected to the circuit board 8. When power is supplied to the power port 11, the screen 3 lights up, enabling the display module to enter the working state. When the corresponding area of ​​the screen 3 is touched, the control board 2 can send different drive waveforms to the vibrator 4 according to the preset vibration feedback based on the contact time, thereby exciting the vibrator 4 to vibrate and realizing the vibration feedback of the integrated vibration structure including the support plate 5, the screen 3, and the protective frame 7.

[0060] This application provides a vibration control method for a display module, the vibration control method comprising: S101 receives touch commands from the screen; Receiving touch commands from the screen enables the display module to sense user actions, converting physical touch gestures into electrical signals or digital commands. This provides the necessary information for subsequent feedback based on user input. By receiving touch commands, the display module can proactively respond to user actions, allowing users to control the module's behavior more directly. This increases user engagement and sense of control, thereby enhancing the user experience.

[0061] S102, outputs the corresponding vibration signal according to the touch type of the touch command; Touch commands include tap commands, swipe commands, and long press commands.

[0062] In the above embodiments, outputting corresponding vibration signals based on different touch types provides users with more accurate and predictable vibration feedback. For example, a tap command might correspond to a brief but strong vibration, allowing the user to feel that the operation has been confirmed; a swipe command might correspond to a continuous and gentle vibration, simulating the tactile sensation of swiping; and a long press command might correspond to a gradually increasing or decreasing vibration, indicating to the user that a long press operation is in progress. This precise vibration feedback helps users better understand whether their operation was successful, improving the accuracy and efficiency of the operation.

[0063] In some embodiments, after receiving a touch command from the screen, the system further includes determining whether the touch was accidental. Specifically, the control board processes the acquired touch command signal. If it determines whether the touch was accidental, and if not, it outputs different drive signals to the vibrator according to different touch commands, thereby generating different vibration feedback. If it determines that the touch was accidental, the acquired touch command signal is not processed.

[0064] This application provides an electronic device, which includes the display module described above.

[0065] In the electronic device provided in this application embodiment, the display module includes a housing 1 and a control board 2, with the control board 2 fixed inside the housing 1; a screen 3 and at least one vibrator 4, with the screen 3 disposed on the upper part of the control board 2 and the vibrator 4 disposed between the control board 2 and the screen 3; the vibrator 4 includes a piezoelectric sheet 41 and a conical vibrating part 42, with the outer ring of the conical vibrating part 42 connected to the piezoelectric sheet 41, and the middle part of the conical vibrating part 42 able to stop the screen 3, the piezoelectric sheet 41 driving the conical vibrating part 42 to deform, thereby providing the screen 3 with high-intensity vibration feedback corresponding to the touch operation, which can give the user sufficient and clear tactile signals, enabling the user to accurately judge the operation status, and improving the intuitiveness and accuracy of the electronic device interaction.
