Description

Technical Field

[0001] This utility model relates to the field of touch screen technology, and in particular to a composite structure of a touch screen surface textured light-transmitting film. Background Technology

[0002] With the widespread adoption of smart terminal devices and the continuous upgrading of user experience demands, touchscreens, as the core interface for human-computer interaction, are increasingly becoming the focus of industry competition in terms of performance and appearance design. In fields such as consumer electronics, automobiles, and smart homes, users not only require touchscreens to have precise and sensitive touch operation functions, but also expect them to be deeply integrated into usage scenarios, achieving an organic unity of aesthetics and practicality.

[0003] However, the traditional touchscreen surface texture and light-transmitting film composite structure often presents a monotonous black or grayish-white screen surface when it is off, which is difficult to integrate with the overall interior style of the device and has poor aesthetics. When the screen is on, it can also affect driving safety by distracting the driver's attention.

[0004] For example, the increased number of in-vehicle touchscreens makes the interior layout more complex. The obtrusive appearance of traditional touchscreens when turned off disrupts the overall aesthetics of the interior and fails to meet consumers' desire for a high-end, refined in-vehicle environment. Furthermore, when a car is exposed to direct sunlight while driving, the reflection and scattering of light from traditional touchscreens can distract the driver and affect driving safety. Utility Model Content

[0005] This utility model discloses a composite structure of a textured light-transmitting film for touch screens, aiming to solve the technical problem that traditional textured light-transmitting film composite structures for touch screens often present a monotonous black or grayish-white screen surface when closed, which is difficult to integrate with the overall interior style of the device and has poor aesthetics. When the screen is turned on, it can also affect driving safety by distracting the driver's attention.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A touchscreen surface textured light-transmitting film composite structure includes a glass cover and a display screen, and further includes: a display mechanism: the display mechanism includes a light-transmitting film connected to the bottom outer wall of the glass cover, an optical adhesive connected to the bottom outer wall of the light-transmitting film, a sensor connected to the bottom outer wall of the optical adhesive, a shielding plate connected to the bottom outer wall of the sensor, and another optical adhesive connected to the bottom outer wall of the shielding plate; and a fixing mechanism: the fixing mechanism is located inside the glass cover.

[0008] This solution uses a translucent film as a carrier and employs interference light printing and pigment stacking printing techniques to achieve the conversion between reflected light and transmitted light. This allows the touchscreen to display a natural wood grain effect when closed and maintain high light transmittance and clear display when open. At this time, the refractive index matching of the optical adhesive reduces the reflection and scattering of light at the interface, optimizes optical performance, and improves display clarity and uniformity. Meanwhile, the shielding plate installed below the sensor can effectively block external electromagnetic interference and prevent external electromagnetic signals from affecting the sensor and other internal circuits.

[0009] In a preferred embodiment, the fixing mechanism includes an installation groove installed inside the glass cover plate, a plurality of reinforcing ribs are connected at equal intervals inside the glass cover plate, epoxy resin adhesive is installed inside the glass cover plate, and a plurality of slots are provided on the outer walls of both sides of the epoxy resin adhesive, and the reinforcing ribs match the slots.

[0010] In this solution, an installation groove is created inside the glass cover to provide installation space for the epoxy resin adhesive. At this time, reinforcing ribs are arranged at equal intervals inside the glass cover to improve the structural strength of the glass cover, enabling it to withstand greater external forces. At the same time, the reinforcing ribs, combined with the cured epoxy resin adhesive, can enhance the stability of the epoxy resin adhesive after installation.

[0011] As described above, a touchscreen surface textured light-transmitting film composite structure includes a glass cover and a display screen, and further includes: a display mechanism: the display mechanism includes a light-transmitting film connected to the bottom outer wall of the glass cover, an optical adhesive connected to the bottom outer wall of the light-transmitting film, a sensor connected to the bottom outer wall of the optical adhesive, a shielding plate connected to the bottom outer wall of the sensor, and another optical adhesive connected to the bottom outer wall of the shielding plate; and a fixing mechanism: the fixing mechanism is located inside the glass cover. The touchscreen surface textured light-transmitting film composite structure provided by this utility model has the technical effects of improving the overall aesthetics of the vehicle interior, enhancing driver attention, and strengthening the edge bonding between the glass cover and the light-transmitting film.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0017] The touch screen surface texture light-transmitting film composite structure disclosed in this utility model is mainly applied to the traditional touch screen surface texture light-transmitting film composite structure. When the screen is closed, the screen surface often appears as a monotonous black or grayish-white, which is difficult to integrate with the overall interior style of the device and has poor aesthetics. When the screen is turned on, it can also affect driving safety by distracting the driver's attention.

[0018] Reference Figure 1 , Figure 2 and Figure 3 A touchscreen surface textured light-transmitting film composite structure includes a glass cover plate 1 and a display screen 6, and further includes: a display mechanism: the display mechanism includes a light-transmitting film 2 connected to the bottom outer wall of the glass cover plate 1, an optical adhesive 3 connected to the bottom outer wall of the light-transmitting film 2, a sensor 4 connected to the bottom outer wall of the optical adhesive 3, a shielding plate 5 connected to the bottom outer wall of the sensor 4, and another optical adhesive 3 connected to the bottom outer wall of the shielding plate 5; a fixing mechanism: the fixing mechanism is located inside the glass cover plate 1.

[0019] By using the translucent film 2 as a carrier, and then using interference light printing technology to reflect light and pigment stacking printing technology to transmit light, the conversion between (reflected light) and (transmitted light) is achieved. This allows the touchscreen to present a natural wood grain effect when it is off, and to maintain high light transmittance and clear display when it is on. At this time, the refractive index matching of the optical adhesive 3 reduces the reflection and scattering of light at the interface, optimizes optical performance, and improves display clarity and uniformity. Meanwhile, the shielding plate 5 installed below the sensor 4 can effectively block external electromagnetic interference and prevent external electromagnetic signals from affecting the sensor 4 and other internal circuits.

[0020] The surface of the light-transmitting film 2 is decorated with a wood grain texture. The wood grain texture is added to the surface of the light-transmitting film 2 through screen printing, so that the display screen 6 presents a seamless wood grain effect when it is closed, while maintaining a clear display when it is open.

[0021] Among them, the light-transmitting film 2 is made of film material that has been screen-printed, so that the display screen 6 can maintain good display function under different lighting conditions.

[0022] Reference Figure 2 and Figure 3 In a preferred embodiment, the fixing mechanism includes an installation groove installed inside the glass cover plate 1. Multiple reinforcing ribs 9 are connected at equal intervals inside the glass cover plate 1. Epoxy resin adhesive 7 is installed inside the glass cover plate 1. Multiple slots 8 are provided on the outer walls of both sides of the epoxy resin adhesive 7. The reinforcing ribs 9 match the slots 8.

[0023] By creating an installation groove inside the glass cover plate 1, an installation space is provided for the epoxy resin adhesive 7. At this time, by arranging reinforcing ribs 9 at equal intervals inside the glass cover plate 1, the structural strength of the glass cover plate 1 is improved, enabling it to withstand greater external forces. Meanwhile, the reinforcing ribs 9, combined with the cured epoxy resin adhesive 7, can enhance the stability of the epoxy resin adhesive 7 after installation.

[0024] Multiple reinforcing ribs 9 are installed at equal intervals on both sides of the inner wall of the mounting groove. By installing multiple reinforcing ribs 9 on both sides of the inner wall of the mounting groove, the strength of the outer wall of the edge of the glass cover plate 1 is enhanced.

[0025] Specifically, epoxy resin adhesive 7 is installed inside the mounting groove to further enhance the sealing performance.

[0026] Reference Figure 2 In a preferred embodiment, the display screen 6 is attached to the bottom outer wall of one of the optical adhesives 3.

[0027] By installing one optical adhesive 3 between the light-transmitting film 2 and the sensor 4, and another optical adhesive 3 between the shielding plate 5 and the display screen 6, light can be transmitted efficiently between different optical components, reducing light reflection and absorption, thereby ensuring the brightness and clarity of the displayed image.

[0028] Working principle: In use, a light-transmitting film 2 is first installed on the bottom outer wall of the glass cover plate 1. Using the light-transmitting film 2 as a carrier and the core carrier, interference light RGB printing technology (reflected light) and pigment stacking CMYK printing technology (transmitted light) work together. When the display screen 6 is in the off state, based on the interference light RGB printing technology, a specific wavelength of reflected light is formed on the surface of the light-transmitting film 2 using the principle of light interference, presenting a natural wood grain effect. At the same time, when the display screen 6 is turned on, the display screen 6 emits light. When the light passes through the light-transmitting film 2, since the light-transmitting film 2 is made of a high light transmittance material, it can ensure efficient light transmission. At the same time, it works in conjunction with the light emitted by the display screen 6 to keep the display screen 6 high light transmittance and clear display. Secondly, an installation groove is opened inside the glass cover plate 1 to provide space for the epoxy resin adhesive 7 to be installed. At this time, by connecting multiple reinforcing ribs 9 at equal intervals inside the glass cover plate 1, when the glass cover plate 1 is subjected to external forces such as collisions and compression, the reinforcing ribs 9 can disperse the external forces, thereby enhancing the structural strength of the glass cover plate 1.

[0029] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
