Description

Technical Field

[0001] This utility model relates to the field of Android display module technology, specifically to an Android display module with touch feedback function. Background Technology

[0002] With the widespread use of Android devices, users have increasingly higher demands for touch experience. Traditional Android display modules can only detect user touch operations and provide corresponding interface feedback, but lack haptic feedback, making users feel a lack of realism and immersion during operation.

[0003] Currently, while some Android devices are equipped with simple vibration feedback, their feedback methods are limited and cannot provide diverse tactile feedback based on different touch operations. For example, when a user clicks an icon, swipes the screen, or types text, the vibration feedback provided by the device is almost identical, failing to provide clear operation prompts and reducing the user's operating experience. In addition, in traditional Android display modules, display functions and touch feedback functions are usually independent of each other. This not only increases the complexity and cost of the module but also occupies more internal space, which is not conducive to the thin and light design of the device. Utility Model Content

[0004] In view of the problems existing in the above-mentioned Android display modules, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an Android display module with haptic feedback function, which solves the problem that in traditional Android display modules, the display function and haptic feedback function are usually independent of each other. This not only increases the complexity and cost of the module, but also occupies more internal space, which is not conducive to the thin and light design of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An Android display module with touch feedback function includes a display module body. The display module body includes a glass cover, a nano-touch sensing layer, an OLED display layer, a piezoelectric ceramic feedback layer, a flexible circuit board layer, and a ceramic thermal conductive layer. The nano-touch sensing layer is fixedly connected to the lower surface of the glass cover, the OLED display layer is fixedly connected to the lower surface of the nano-touch sensing layer, the piezoelectric ceramic feedback layer is fixedly connected to the lower surface of the nano-touch sensing layer, the flexible circuit board layer is fixedly connected to the lower surface of the piezoelectric ceramic feedback layer, and the ceramic thermal conductive layer is fixedly connected to the lower surface of the flexible circuit board layer.

[0008] Preferably, the glass cover is 2.5D Gorilla Glass with nanoscale textures etched on its surface.

[0009] Preferably, the nano-touch sensing layer is a self-capacitive screen.

[0010] Preferably, the piezoelectric ceramic feedback layer is a lead zirconate titanate piezoelectric film, and the thickness of the piezoelectric ceramic feedback layer is 0.15 mm.

[0011] Preferably, the surface of the flexible circuit board layer is provided with an integrated touch signal amplification circuit and a feedback drive circuit.

[0012] Preferably, an IMU sensor is fixedly connected to the surface of the flexible circuit board layer.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model integrates functional layers such as the nano-touch sensing layer, OLED display layer, and piezoelectric ceramic feedback layer into the same display module body, replacing the traditional stacking mode of independent components. This significantly reduces module complexity and assembly costs, while also reducing internal space occupation, providing strong support for the thinner and lighter design of Android devices and improving device portability.

[0015] 2. This utility model uses a lead zirconate titanate piezoelectric film with a thickness of only 0.15mm for the piezoelectric ceramic feedback layer. It can generate precise vibration feedback according to different touch operations, such as clicking, sliding, and pressing. Combined with the 4096-level pressure sensing and 20-point simultaneous touch function of the self-capacitive screen, it realizes the diversification and refinement of tactile feedback, enhances the realism and immersion of user operation, and optimizes the interactive experience.

[0016] 3. This utility model integrates a touch signal amplification circuit and a feedback drive circuit through a flexible circuit board layer to amplify and filter the touch signal in real time, ensuring the accuracy of signal transmission; the ceramic heat-conducting layer can quickly dissipate the heat of the OLED display layer and the flexible circuit board layer, avoiding overheating from affecting the performance of the components; combined with the IMU sensor to sense the device posture in real time and dynamically adjust the feedback parameters, the stability and adaptability of the module are further improved.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses an Android display module with touch feedback function.

[0025] This utility model provides, for example Figure 1-3 An Android display module with haptic feedback function is shown, including a display module body 1. The display module body 1 includes a glass cover plate 2, a nano-touch sensing layer 3, an OLED display layer 4, a piezoelectric ceramic feedback layer 5, a flexible circuit board layer 6, and a ceramic thermal conductive layer 7. The nano-touch sensing layer 3 is fixedly connected to the lower surface of the glass cover plate 2, the OLED display layer 4 is fixedly connected to the lower surface of the nano-touch sensing layer 3, the piezoelectric ceramic feedback layer 5 is fixedly connected to the lower surface of the nano-touch sensing layer 3, the flexible circuit board layer 6 is fixedly connected to the lower surface of the piezoelectric ceramic feedback layer 5, and the ceramic thermal conductive layer 7 is fixedly connected to the lower surface of the flexible circuit board layer 6.

[0026] The touch sensing nano-touch sensing layer 3, the display OLED display layer 4, the feedback piezoelectric ceramic feedback layer 5, and the signal processing flexible circuit board layer 6 are integrated into the same module, reducing the stacking of traditional independent components, reducing complexity and cost, while saving internal space of the device and supporting a thin and light design.

[0027] To protect the display module, such as Figure 1-2 As shown, the glass cover 2 is 2.5D Gorilla Glass, with nanoscale textures etched on its surface.

[0028] 2.5D Gorilla Glass has high strength, which not only improves its drop and wear resistance, but also enhances the tactile recognition of fingers through nano-level texture, reduces fingerprint residue and improves light transmittance, thus optimizing the visual display effect.

[0029] like Figure 1-2 As shown, the nano-touch sensing layer 3 is a self-capacitive screen.

[0030] It adopts self-capacitive touch technology, reduces the electrode spacing to 50μm, and supports 4096 levels of pressure sensitivity and 20-point simultaneous touch.

[0031] To provide feedback for touch, such as Figure 1-2 As shown, the piezoelectric ceramic feedback layer 5 is a lead zirconate titanate piezoelectric film, and the thickness of the piezoelectric ceramic feedback layer 5 is 0.15 mm.

[0032] After the touch signal is processed, the driving circuit applies an electrical signal to the piezoelectric ceramic feedback layer 5, causing it to undergo mechanical deformation and vibrate, thereby providing tactile feedback to the user.

[0033] like Figure 1-2 As shown, the surface of the flexible circuit board layer 6 is provided with an integrated touch signal amplification circuit and a feedback drive circuit, and an IMU sensor is fixedly connected to the surface of the flexible circuit board layer 6.

[0034] The surface-integrated touch signal amplification circuit amplifies and filters weak touch signals to ensure signal accuracy and stability. At the same time, the IMU sensor can detect the device's posture in real time, such as tilt and shaking, and dynamically adjust the feedback parameters.

[0035] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
