Description

Technical Field

[0001] This invention belongs to the field of display devices, specifically relating to an expandable multi-screen cover, display module, and electronic device. Background Technology

[0002] With continuous technological advancements and increasing consumer demands for product performance, traditional glass covers are gradually proving inadequate to meet the needs of multifunctionality, high durability, and aesthetics in electronics, automobiles, and outdoor applications. In particular, higher functional requirements are being placed on glass covers. Besides high transparency and good physical support, they must also possess properties such as UV resistance, high-temperature resistance, and abrasion resistance, while providing functions like temperature indication and anti-reflection. Therefore, developing a new type of multifunctional integrated glass cover has become a major technological imperative.

[0003] Existing multi-screen display devices typically employ a combination of a glass cover and a display panel structure. However, in practical applications, the weak connection between the glass cover and the display panel results in an unstable bond, making them susceptible to damage from external forces. Furthermore, traditional glass covers often fail to provide real-time feedback on temperature changes in complex environments, thus hindering the improvement of the user experience.

[0004] Therefore, solving the problems of stable connection and functional integration of multi-screen cover plates, and improving their durability, UV resistance, high temperature resistance and visual effect have become urgent problems to be solved in current technology. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-screen cover plate with an expandable splicing structure and a multi-layer coating combination, as well as a display module and electronic device using the multi-screen cover plate.

[0006] To solve the above-mentioned technical problems, the technical method adopted by the present invention is as follows: The present invention discloses an expandable multi-screen cover glass, including a main cover glass and an expansion cover glass arranged in parallel;

[0007] On the back of the main cover glass, a plastic block is provided on one edge adjacent to the expansion cover.

[0008] On the back of the expandable cover glass, a plastic connecting block is provided on one edge adjacent to the main cover glass. One end of the plastic connecting block is fixed to the back of the expandable cover glass, and the other end extends to one side of the main cover glass. The plastic connecting block is provided with a fixing groove that can fit the plastic block.

[0009] Both the main cover glass and the expansion cover glass have a front coating layer, which includes a zinc oxide layer, a molybdenum oxide layer and a boron oxide layer arranged sequentially from the inside to the outside.

[0010] Both the main cover glass and the expansion cover glass have a back coating layer on their back sides. The back coating layer includes a thermochromic ink layer and an acrylic resin protective layer arranged sequentially from the inside to the outside.

[0011] Furthermore, both the plastic block and the plastic connecting block are disposed below the thermochromic ink layer.

[0012] Furthermore, the thickness of the zinc oxide layer is 80-120 nanometers.

[0013] Furthermore, the thickness of the molybdenum oxide layer is 50-100 nanometers.

[0014] Furthermore, the thickness of the boron oxide layer is 110-150 nanometers.

[0015] Furthermore, the thickness of the thermochromic ink layer is 5-10 micrometers, and the thickness of the acrylic resin protective layer is 15-19 micrometers.

[0016] Furthermore, an air gap layer is provided between the main cover glass and the expansion cover glass, and the thickness of the air gap layer is 0.1-0.3 mm.

[0017] The present invention also discloses a display module, including any of the above-mentioned expandable multi-screen cover plates, and a backlight module disposed within the expandable multi-screen cover plate.

[0018] The present invention also discloses an electronic device, including the above-described display module and a touch screen and circuit components integrated on the display module.

[0019] Furthermore, the circuit assembly includes a flexible circuit board, which is fixed to the non-coated area on the back of the main cover glass by conductive adhesive.

[0020] Beneficial effects:

[0021] 1. Compared to existing technologies, the expandable multi-screen cover structure of this invention effectively enhances the connection stability between the two glass panels by setting a plastic block and a plastic connecting block between the main cover glass and the expandable cover glass. One end of the plastic connecting block is fixed to the back of the expandable cover glass, and the other end extends to the main cover glass. The interlocking design achieves a tight fixation, avoiding the problem of loosening or breaking of traditional glass cover connections due to external forces. This design not only improves the stable connection between the two glass panels but also meets the needs of large-size displays, supports more flexible splicing expansion, and satisfies the stability and expandability requirements of multi-screen display devices.

[0022] 2. This invention significantly improves the durability of glass covers by employing multi-layer coating technology and an acrylic resin protective layer. Coatings of zinc oxide, molybdenum oxide, and boron oxide effectively enhance the glass's abrasion resistance, UV resistance, and high-temperature resistance, extending the cover's service life. Furthermore, the thermochromic ink layer is located beneath the protective layer, avoiding the risk of damage to the directly exposed ink layer. The acrylic resin protective layer possesses excellent abrasion resistance and chemical corrosion resistance, effectively preventing the ink layer from losing function or appearance due to scratches or friction during daily use, further enhancing the overall structural durability and service life.

[0023] 3. The glass cover of this invention is equipped with a temperature-sensitive color-changing ink layer, which can change color with temperature changes, providing users with intuitive temperature feedback. This temperature indication function not only increases the interactivity of the product but also enhances the fun of using it. Through this visual feedback of temperature changes, users can more clearly understand the working status of the product or the temperature changes of the external environment, greatly enhancing the practicality of the product and the user experience, especially important in some application scenarios that require temperature control or high-temperature environments.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0028] Example 1: An expandable multi-screen cover

[0029] This embodiment provides an expandable multi-screen cover plate suitable for large-size displays. The cover plate consists of two pieces of glass, namely a main cover glass 1 and an expansion cover glass 2. On the back of the main cover glass 1 and the edge adjacent to the expansion cover glass 2, plastic blocks 12 and plastic connecting blocks 21 are respectively provided.

[0030] One end of the plastic connecting block 21 is fixed to the back of the expansion cover glass 2, and the other end extends to the back of the main cover glass 1. The plastic block 12, through its interlocking design, cooperates with the fixing groove 211 on the plastic connecting block 21 to form a robust connection structure, effectively increasing the stability and shock resistance between the two glass panels.

[0031] In this design, the plastic block 12 and the plastic connecting block 21 are preferably made of engineering plastics such as polycarbonate (PC) or nylon (PA), which have high heat resistance, chemical corrosion resistance, and good processing performance. These materials can maintain stability during long-term use and ensure that the connecting parts do not deform or fall off under different temperature and humidity conditions.

[0032] To improve the light transmittance and UV resistance of the main cover glass 1 and the extension cover glass 2, a multi-layer coating process was used on the glass surface.

[0033] First, both the main cover glass 1 and the extension cover glass 2 are coated with a zinc oxide layer 31, the thickness of which is controlled between 80-120 nanometers, providing good light transmittance and UV resistance. Second, a molybdenum oxide layer 32 is coated on top of the zinc oxide layer 31, with a thickness controlled between 50-100 nanometers, reducing light reflectivity and optimizing the display effect. Finally, to improve the high-temperature resistance of the cover glass, a boron oxide layer 33 is applied, with a thickness of 110-150 nanometers. The boron oxide layer 33 possesses excellent thermal and chemical stability, effectively preventing deformation or damage to the glass under high-temperature conditions.

[0034] This design ensures a stable connection between the main cover glass 1 and the expansion cover glass 2, while also guaranteeing the optical performance and mechanical strength of the entire cover, meeting the requirements for large-size displays.

[0035] More preferably, at the edges of the main cover glass 1 and the expansion cover glass 2, there is also an expansion plastic block 5 with the same structure and function as the plastic block 12.

[0036] Example 2: Display Module

[0037] In this embodiment, the aforementioned expandable multi-screen cover plate is applied to a display module. The display module includes the main cover glass and the expansion cover glass of the aforementioned expandable multi-screen cover plate, as well as a backlight module disposed inside the cover plate.

[0038] The backlight module design ensures uniform illumination and high brightness output for the display module, meeting the usage requirements of large-screen displays in different environments.

[0039] The backlight module contains multiple LED light sources. Through reasonable layout and circuit design, the light sources can be evenly distributed, avoiding the problem of uneven brightness that occurs in traditional backlight modules.

[0040] Preferably, the backlight module and the expandable multi-screen cover are connected via a flexible circuit board, which is fixed to the non-coated area on the back of the main cover glass 1 using conductive adhesive. This design ensures stable power and signal transmission without affecting the optical performance of the glass surface.

[0041] The display module has a wide range of applications, including flat panel displays, televisions, billboards, and other devices requiring large-size displays. This display module not only boasts high brightness and clarity but also enables seamless splicing, providing users with a more immersive display experience.

[0042] Example 3: Electronic Equipment

[0043] This embodiment provides an electronic device including the above-described display module. The electronic device integrates a touchscreen and circuit components. The touchscreen can respond to user input, while the circuit components are connected to the main cover glass 1 via a flexible circuit board, providing power and signal transmission functions.

[0044] In this embodiment, the display module of the electronic device includes the aforementioned expandable multi-screen cover and backlight module, while the touch screen is fixed to the non-coated area of ​​the main cover glass 1 by conductive adhesive.

[0045] To ensure the performance and reliability of the equipment, the circuit components utilize a flexible printed circuit board (FPC) design. This not only saves space but also allows the circuit board to more flexibly adapt to the needs of devices of different sizes and shapes. By connecting the flexible circuit board to the non-coated area of ​​the main cover glass, interference from the circuit components to the optical or coating layers is avoided, ensuring display quality and stability.

[0046] This electronic device offers significant improvements in display performance, stability, functionality, and aesthetics. The touchscreen boasts high responsiveness and accuracy, while its integrated design with the display module makes the overall device more compact and efficient. Whether for smartphones, tablets, automotive display systems, or other consumer electronics, this embodiment provides an ideal solution to meet market demands for high-performance display devices.
