[0031] At present, there are many kinds of touch display screens on the market, which are a kind of the latest computer input device. However, the anti-collision effect of the common touch display screen is poor, which may be impacted by the outside or fall to the ground during use. The impact has a great influence on the touch display screen, and even causes damage. Sometimes, strong impact can easily cause the whole machine of the touch display screen to deform, resulting in the internal parts of the touch display screen falling off or loosening, and further causing the touch screen to jump, the touch to be unresponsive and other failures or damages, thereby greatly reducing the service life of the touch display screen and bringing great inconvenience to the user.

[0032] In order to solve the above problems, the present application provides a touch display device.

[0033] Please refer to Figs. 1 to 3 In an embodiment of the present application, the touch display device comprises a display screen 1, a touch screen 2, a buffer layer 3 and a protective layer 4, the touch screen 2 is arranged on one side of the display screen 1; the buffer layer 3 is arranged between the touch screen 2 and the display screen 1, the buffer layer 3 surrounds the periphery of the touch screen 2, and the buffer layer 3 is adhered to the touch screen 2 and the display screen 1 respectively; the protective layer 4 is connected to the side of the touch screen 2 away from the buffer layer 3.

[0034] In the structure, the buffer layer 3 is arranged between the touch screen 2 and the display screen 1 and surrounds the periphery of the touch screen 2, so that when the touch display device is impacted by an external force, the buffer layer 3 can effectively absorb and disperse the impact force and reduce the transmission of the impact energy to the touch screen 2 and the display screen 1, thereby reducing the risk of damage to the touch screen 2 and the display screen 1 due to the impact. The protective layer 4 is connected to the side of the touch screen 2 away from the buffer layer 3 and directly faces the external environment, so that the protective layer 4 can resist scratches, collisions and other damages from the external environment, thereby playing the role of the first line of defense, reducing the direct damage to the surface of the touch screen 2 and prolonging the service life of the touch screen 2. In addition, the protective layer 4 improves the structural strength and stability of the touch display device as a whole, so that the touch display device can better maintain the integrity of the shape and structure when subjected to an external force, thereby improving the anti-impact performance of the device. The buffer layer 3 and the protective layer 4 cooperate to form an effective protection system. The buffer layer 3 absorbs and disperses the impact force inside the touch display device, and the protective layer 4 resists direct damage outside the touch display device. The two work together to significantly improve the anti-impact performance of the touch display device, thereby greatly reducing the probability of damage to the touch display screen 1 due to impact and effectively prolonging the service life of the touch display screen 1.

[0035] In an embodiment, the buffer layer 3 includes a first adhesive layer 31 and an elastic layer 32, both of which are arranged between the touch screen 2 and the display screen 1. The first adhesive layer 31 surrounds the periphery of the touch screen 2, and the elastic layer 32 is arranged along the inner side of the first adhesive layer 31.

[0036] In the structure, the buffer layer 3 comprises the first adhesive layer 31 and the elastic layer 32, further improving the anti-impact performance of the touch display device. Specifically, the first adhesive layer 31 is arranged around the periphery of the touch screen 2, which can firmly bond the touch screen 2 and the display screen 1 together, ensuring that they are tightly combined in the normal working state and will not easily separate due to external force, thereby maintaining the integrity and stability of the touch display device. The elastic layer 32 is arranged around the inner side of the first adhesive layer 31, which can elastically deform when the device is impacted, absorb a large amount of impact energy, and effectively disperse and resolve the impact force, thereby protecting the touch screen 2 and the display screen 1 from impact damage to the greatest extent. The elastic properties of the elastic layer 32 enable it to quickly recover to its original state after being impacted, providing continuous cushioning protection for the device. The circumferential arrangement of the elastic layer 32 can uniformly disperse the impact force to the periphery of the touch screen 2 and the display screen 1, avoiding damage to local areas due to excessive stress, making the stress of the entire device more uniform, and further improving the anti-impact performance. The firm bonding effect of the first adhesive layer 31 combined with the cushioning protection effect of the elastic layer 32 enables the touch screen 2 and the display screen 1 to better maintain their relative positions and structural integrity when subjected to external forces, reducing problems such as internal structural misalignment and damage of the touch display device caused by impact, thereby greatly prolonging the service life of the touch display screen 1.

[0037] In an embodiment, the thickness of the elastic layer 32 ranges from 0.7 to 0.9 mm.

[0038] In the above structure, the thickness of the first adhesive layer 31 is controlled to be 0.7-0.9 mm, so that the first adhesive layer 31 provides sufficient material to achieve firm adhesion between the touch screen 2 and the display screen 1. In normal use and under the action of a certain external force, the two can be tightly combined and will not easily separate, maintaining the overall structure of the touch display device. For example, in daily use, even if the device is subjected to a certain degree of extrusion or impact, the first adhesive layer 31 can keep the relative positions of the touch screen 2 and the display screen 1 stable. When the touch display device is impacted, the first adhesive layer 31 has a certain buffering capacity and can slow down the transmission speed of the impact force, giving the elastic layer 32 more time for further buffering, thereby improving the buffering effect of the entire buffer layer 3. Strict control of the thickness precision of the first adhesive layer 31 can ensure the consistency of the adhesion strength. If the thickness deviation is too large, the adhesion strength may be unstable, and some products may have a loose adhesion, affecting the service life and reliability of the touch display device. Controlling the thickness precision within the range of 0.7-0.9 mm can make the adhesion strength of each product meet the design requirements and ensure product quality. The appropriate thickness precision range is also conducive to optimizing the buffering performance of the entire buffer layer 3. The thickness of the first adhesive layer 31 and the elastic layer 32 cooperates with each other to achieve the best buffering effect when impacted. By precisely controlling the thickness of the first adhesive layer 31, it can be ensured that it works cooperatively with the elastic layer 32 to achieve the expected anti-impact performance and improve the overall quality of the product.

[0039] In an embodiment, the thickness of the first adhesive layer 31 is in the range of 0.7-0.9 mm.

[0040] In the above structure, the elastic layer 32 can effectively buffer the impact force when subjected to external force impact, provide deformation space to absorb and disperse impact energy, and reduce the direct impact on the touch screen 2 and the display screen 1, thereby better protecting the internal structure of the touch display device and reducing the risk of damage due to impact. The thickness of the first adhesive layer 31 is also 0.7-0.9 mm, which matches the thickness of the elastic layer 32, so that the two can work better in cooperation during the buffering process. While the first adhesive layer 31 preliminarily absorbs impact energy and slows down the transmission of impact force, the elastic layer 32 can fully exert its high-efficiency buffering effect, and the two work together to further improve the buffering performance of the entire buffer layer 3 and provide stronger anti-impact protection for the touch display device.

[0041] In an embodiment, the elastic layer 32 includes a rubber layer or a sponge layer or an EVA material layer.

[0042] The rubber has excellent elastic properties and can be greatly elastically deformed when subjected to external force impact, thereby absorbing and dispersing a large amount of impact energy, so as to provide effective buffer protection for the touch screen 2 and the display screen 1. When the external force disappears, the rubber can quickly recover to the original state, maintaining good buffering effect. The sponge has soft texture and can be closely attached to the touch screen 2 and the display screen 1, providing uniform buffering effect. When subjected to external force impact, the sponge can quickly deform, absorb impact energy, and reduce the direct impact on the touch screen 2 and the display screen 1, thereby playing a good buffering role. The EVA (ethylene-vinyl acetate copolymer) material has good elasticity and softness, and can provide effective buffer protection. At the same time, the EVA material also has good low-temperature resistance and can maintain a certain elasticity in cold environments without becoming brittle, ensuring normal use of the touch display device in low-temperature environments. The rubber layer, the sponge layer or the EVA material layer is used as the elastic layer 32, which can provide appropriate elastic buffering performance for the touch display device according to different application scenarios and requirements, effectively solve the problem of poor anti-impact performance of the existing touch display device, and prolong the service life thereof.

[0043] In an embodiment, the buffer layer 3 further comprises a wear-resistant layer 33, the wear-resistant layer 33 is arranged around the display screen 1, one side of the wear-resistant layer 33 is connected with the first adhesive layer 31 and the elastic layer 32, and the wear-resistant layer 33 is connected with the side of the display screen 1 close to the touch screen 2.

[0044] In the above structure, the wear-resistant layer 33 is connected with the first adhesive layer 31 and the elastic layer 32, and the wear-resistant layer 33 is located on the side of the elastic layer 32 close to the display screen 1, wherein the elastic layer 32 and the first adhesive layer 31 are connected with the touch screen 2, and the wear-resistant layer 33 is in abutment with the display screen 1. By adding the wear-resistant layer 33, direct contact between the elastic layer 32 and the display screen 1 is avoided, the surface wear resistance of the elastic layer 32 is greatly improved, so that the elastic layer 32 can maintain good state during long-term use without being damaged too early due to wear, thereby prolonging the service life of the buffer layer 3 and further improving the service life of the entire touch display device.

[0045] In an embodiment, the wear-resistant layer 33 comprises a silicon nitride ceramic layer or an AlCrSiN functional layer.

[0046] In the above structure, the silicon nitride is a high-hardness material, which can effectively resist external wear and friction of the touch display device and maintain the integrity of the material. The hardness and strength of the material make it have a long service life in a wear environment. The AlCrSiN functional layer has high hardness and excellent wear resistance, which can effectively resist wear. By the method of pulse arc ion plating, a layer of high-hardness AlCrSiN functional layer can be deposited on the surface of the substrate, which can significantly improve the wear resistance of the substrate. The use of a silicon nitride ceramic layer or an AlCrSiN functional layer as a wear-resistant layer 33 can significantly improve the wear resistance of the buffer layer 3, prolong the service life of the buffer layer 3, and improve the reliability and stability of the product.

[0047] In an embodiment, the thickness of the wear-resistant layer 33 is in the range of 0.13-0.17 mm. Controlling the thickness of the wear-resistant layer 33 in the range of 0.13-0.17 mm provides sufficient material to resist external wear of the touch display device and effectively reduces the elastic layer 32 while maintaining its good cushioning performance.

[0048] In an embodiment, the protective layer 4 includes a tempered glass layer. The tempered glass layer can effectively resist external impact of the touch display device and reduce damage to the display screen 1 caused by falling, collision, etc. Its high-strength characteristics enable it to absorb and disperse impact energy when subjected to a large impact force, thereby protecting the display screen 1 from direct impact and prolonging the service life of the display screen 1. In addition, the high hardness and wear resistance of the tempered glass can effectively prevent scratches. In daily use, objects such as fingers, keys, and coins frequently come into contact with the touch display device, and the tempered glass layer can prevent these objects from scratching the touch screen 2 and maintaining the good touch performance of the touch screen 2. In addition, the tempered glass layer has high transparency and good touch performance, ensuring that users can have a smooth and accurate touch experience when operating the touch display device. Even after long-term use, the tempered glass layer can still maintain good touch performance and will not affect the operation experience due to wear.

[0049] In an embodiment, the protective layer 4 and the display screen 1 are bonded by a second adhesive layer 6, and the second adhesive layer 6 includes an optical adhesive layer.

[0050] In the above structure, the protective layer 4 and the display screen 1 are bonded by a second adhesive layer 6, and the second adhesive layer 6 includes an optical adhesive layer. The optical adhesive layer is a colorless and transparent optical pressure-sensitive adhesive with high light transmittance, and the light transmittance is close to that of glass. It will not cause yellowing, aging, fogging, etc. after long-term use, and can ensure that the display effect of the display screen 1 is not affected. The optical adhesive layer has high adhesion, which can completely paste the protective layer 4 and the display screen 1 together, reduce screen glare, and improve the display effect. In addition, the first adhesive layer 31 can also use an optical adhesive material.

[0051] In an embodiment, the two corners of at least one side of the display screen 1, the touch screen 2, the protective layer 4, and the buffer layer 3 are provided with a rounded structure.

[0052] In the above structure, the rounded structure provided at the corner of the display screen 1, the touch screen 2, the protective layer 4, and the buffer layer 3 can effectively reduce stress concentration, help to prolong the service life of the display screen 1 and the touch screen 2, reduce the frequency of repair and replacement due to corner damage, and improve the economy and practicality of the product. When subjected to external force impact, the rounded structure can evenly distribute the stress, avoiding cracks or damage at the corner due to stress concentration, thereby improving the structural strength and impact resistance of the entire touch display device. The rounded structure reduces the sharpness of the corner of the touch display device, making the product safer during use and reducing the risk of injury to the human body caused by sharp corners. The cross-sectional shape of the protective layer 4 and the buffer layer 3 is adapted to the shape of the display screen 1 and the touch screen 2, so that the protective layer 4 and the buffer layer 3 can closely adhere to the display screen 1 and the touch screen 2, reducing the air layer and gap, improving the stability of the overall structure, helping to reduce the interlayer separation or misalignment phenomenon caused by external force, ensuring the stability and reliability of the touch display device during long-term use, and providing better protection and buffering for the display screen 1 and the touch screen 2.

[0053] The technical solution of the present application adopts the buffer layer 3 between the touch screen 2 and the display screen 1, and surrounds the four corners of the touch screen 2. When the touch display device is subjected to external impact, the buffer layer 3 can effectively absorb and disperse the impact force, reducing the transmission of impact energy to the touch screen 2 and the display screen 1, thereby reducing the risk of damage to the touch screen 2 and the display screen 1 due to impact. The protective layer 4 is connected to the side of the touch screen 2 away from the buffer layer 3, directly facing the external environment, and can resist external scratches, collisions, and other damage, playing the role of the first line of defense, reducing the direct damage to the surface of the touch screen 2, and prolonging the service life of the touch screen 2. The addition of the protective layer 4 improves the structural strength and stability of the overall touch display device, allowing it to better maintain its shape and structural integrity when subjected to external forces, improving the impact resistance of the device. The buffer layer 3 and the protective layer 4 work together to form an effective protection system. The buffer layer 3 absorbs and disperses the impact force inside the touch display device, and the protective layer 4 resists direct damage on the outside of the touch display device. The two work together to significantly improve the anti-impact performance of the touch display device, thereby greatly reducing the probability of damage to the touch display screen 1 caused by impact, and effectively prolonging its service life.
