Description

Technical Field

[0001] This utility model belongs to the field of touch screen technology, and in particular relates to a waterproof and sealed touch screen. Background Technology

[0002] With the widespread adoption of mobile devices such as smartphones, tablets, and smart wearables, touchscreens, as one of the primary methods of human-computer interaction, have become an indispensable part of modern electronic devices. Touchscreen technology has evolved through several stages, from resistive and surface acoustic wave (SAW) touchscreens to the widely used capacitive touchscreens. Among these, capacitive touchscreens have become the mainstream in the market due to their advantages such as fast response speed, high precision, and support for multi-touch. Although various waterproof technologies exist in the market, the following drawbacks remain:

[0003] The waterproof sealing structure is not comprehensive enough, which means there is still a possibility of water ingress; the external mounting structure of the touch screen lacks drainage structure, which may cause water to accumulate around it, increasing the risk of water ingress; some touch screens adopt a completely sealed method, which improves the waterproof effect, but also affects the heat dissipation of the touch screen, and in the case of a small amount of water ingress, it can only be removed and wiped dry, which is quite cumbersome.

[0004] To address these issues, we provide a waterproof and sealed touchscreen. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a waterproof and sealed touch screen, comprising:

[0007] The glass cover is located on the outermost layer of the touchscreen.

[0008] A touch-sensing layer is disposed beneath the glass cover.

[0009] The liquid crystal display layer is located below the touch sensing layer;

[0010] A waterproof sealing ring is located at the edge of the touchscreen.

[0011] An exhaust vent is located at the top of the touchscreen, and the exhaust vent is embedded with a waterproof and breathable membrane;

[0012] The drainage channels are located around the touchscreen and are connected to the drainage holes inside the device housing.

[0013] The present invention is further provided that the inner side of the waterproof sealing ring is provided with a groove, and the groove is filled with waterproof adhesive.

[0014] The present invention is further configured such that the glass cover, the touch sensing layer and the liquid crystal display layer are fixed by an adhesive, and the adhesive contains a waterproof additive.

[0015] The present invention is further configured to include a waterproof sealing gasket disposed between the touch screen and the device housing.

[0016] The present invention is further configured to include a sealing kit disposed at the connection point of the touch screen.

[0017] The present invention is further configured to include a frame, which is enclosed on the outer edge of the touch screen, and a mounting component is fixed at the corner of the frame.

[0018] This utility model has the following beneficial effects:

[0019] This invention effectively prevents moisture from entering the touchscreen from different angles by setting up waterproof sealing rings, waterproof sealing gaskets, and sealing kits, ensuring its normal operation in humid environments. The drainage channel allows accidentally entering moisture to be guided out in time, reducing the risk of moisture accumulation inside the touchscreen. The vent is embedded with a waterproof and breathable membrane, which can maintain the pressure balance inside and outside the touchscreen, prevent moisture from entering, and help dissipate the heat generated during operation.

[0031] Example

[0032] Please see Figure 1-6 This utility model is a waterproof and sealed touch screen, comprising:

[0033] Glass cover 100, which is located on the outermost layer of the touch screen;

[0034] A touch-sensing layer 200 is disposed below the glass cover plate 100;

[0035] The liquid crystal display layer 300 is located below the touch sensing layer 200;

[0036] A 400 waterproof sealing ring is located at the edge of the touchscreen.

[0037] An exhaust vent 500 is located at the top of the touch screen, and a waterproof and breathable membrane 501 is embedded in the exhaust vent 500.

[0038] The flow channel 600 is located around the touch screen and is connected to the drainage hole inside the device housing;

[0039] A waterproof sealing gasket 700 is installed between the touchscreen and the device housing;

[0040] Sealing kit 800 is installed at the touch screen wiring point;

[0041] A frame 900 is enclosed on the outer edge of the touch screen, and a mounting piece 901 is fixed at the corner of the frame 900.

[0042] Specifically, the glass cover 100, the touch sensing layer 200, and the liquid crystal display layer 300 are fixed together with an adhesive containing a waterproof additive.

[0043] Furthermore, the inner side of the waterproof sealing ring 400 is provided with a groove 401, and the groove 401 is filled with waterproof adhesive.

[0044] This technical solution proposes a waterproof and sealed touchscreen, ensuring its normal operation even in humid environments and preventing water or other liquids from penetrating the touchscreen's interior. This protects the internal electronic components and ensures the touchscreen can operate normally in various harsh environments, especially in applications with high humidity or direct contact with water. A detailed description of this technical solution is as follows:

[0045] The glass cover 100 is the outermost layer of the touchscreen, made of high-strength tempered glass to provide physical protection and wear resistance. It not only enhances the durability of the touchscreen but also provides good light transmittance, ensuring clear image visibility. The touch sensing layer 200 is made of transparent conductive materials such as indium tin oxide (ITO), responsible for detecting changes in the position of a finger or stylus and converting them into electrical signals to be sent to the control system for processing. The liquid crystal display layer 300 is the core component for displaying content. It adjusts the amount of light transmitted by changing the arrangement of liquid crystal molecules, thereby forming different images.

[0046] A waterproof sealing ring 400 is located at the edge of the touch screen to prevent moisture from penetrating into the screen from the edge, and a groove 401 is provided on its inner side, which is filled with waterproof adhesive to increase the sealing performance.

[0047] To allow air circulation while preventing moisture from entering, an exhaust vent 500 is provided on the top of the touch screen. The exhaust vent 500 is embedded with a waterproof and breathable membrane 501, which allows gas molecules to pass through but blocks water droplets, thereby balancing the internal and external pressure difference and maintaining waterproof properties. When the touch screen is working, the heat generated evaporates the trace amount of moisture inside, and the hot air moves upward and is discharged through the exhaust vent 500.

[0048] The drainage channel 600 is located around the touch screen and is connected to the drain hole inside the device housing. If a small amount of water accidentally enters, it can be guided out through the drainage channel 600 to avoid accumulating inside and causing damage.

[0049] A waterproof sealing gasket 700 is placed on the contact surface between the touch screen and the device housing to further enhance the waterproof effect and prevent moisture from seeping in through the gap; a sealing kit 800 is used to protect the touch screen wiring parts from moisture and ensure the waterproof seal at the interface; the frame 900 not only provides structural stability but also helps to fix the touch screen to the device; each corner of the frame 900 is fixed with a mounting piece 901 for easy installation and removal.

[0050] In addition, all layers are fixed together using an adhesive containing waterproof additives, which not only enhances the bonding strength between layers but also improves the overall waterproof performance of the touchscreen.
