[0034] Existing laptop touchscreens mostly use foam adhesive bonding. While this structure meets basic requirements under normal use, its stability and durability are significantly insufficient in harsh environments. For example, under extreme temperatures and humidity, moisture can easily penetrate between the touchscreen and the laptop body, causing circuit shorts or touchscreen failure. In dusty environments, dust easily accumulates at the joint between the touchscreen and the laptop body, affecting the touchscreen's sensitivity and accuracy, and potentially damaging internal components.

[0035] The utility model provides a touch display device.

[0036] See also Figures 1 to 3 In one embodiment of the present invention, the touch display device 100 includes:

[0037] The housing 1 is provided with a mounting groove 11, and a display port 111 is provided at the bottom of the mounting groove 11;

[0038] The touch screen 2 is installed in the installation groove 11, and the touch surface of the touch screen 2 is exposed in the display port 111;

[0039] The display screen 3 is provided on the side of the touch screen 2 facing away from the display port 111 and is electrically connected to the touch screen 2;

[0040] The supporting boss 4 is extended along the circumference of the touch screen 2, and the display screen 3 is provided on the surface of the supporting boss 4 facing away from the housing 1; and

[0041] The sealing member 5 is provided between the supporting boss 4 and the touch screen 2 .

[0042] The technical solution of the present invention is to install the touch screen 2 in the mounting groove 11 on the housing 1 and to provide a display port 111 at the bottom of the mounting groove 11, so that the touch surface of the touch screen 2 is exposed through the display port 111 to realize the touch function of the display screen 3. In this solution, a supporting boss 4 is also provided on the outer periphery of the touch screen 2. The supporting boss 4 can not only provide stable support for the display screen 3, but also prevent the display screen 3 from directly contacting the shell of the housing 1, preventing the user from getting an electric shock when touching the outer surface of the housing 1. In addition, a sealing member 5 is provided in the gap between the supporting boss 4 and the touch screen 2. The provision of the sealing member 5 prevents moisture and dust from entering the gap between the touch screen 2 and the display screen 3, protecting the internal electronic components from damage, and improving the service life and reliability of the touch display device 100 in harsh environments.

[0043] Specifically, the support boss 4 and the housing 1 can be integrally formed or separately processed and then assembled. In addition, the structure of the support boss 4 is not specifically limited. For example, it can be an L-shaped semi-enclosed structure protruding from the mounting groove 11, with part of the edge of the touch screen 2 resting on the support boss 4, and the gap between the two is filled with a sealant 5; see Figure 5 The support boss 4 can also be a double-layer boss, including a first protrusion 42 and a second protrusion 43 provided on the outer periphery of the first protrusion 42, and the inner side surface of the second protrusion 43 is arranged to coincide with the outer side surface of the first protrusion 42, wherein the inner side surface of the first protrusion 42 is arranged to abut against the peripheral side surface of the touch screen 2, and the top surface of the second protrusion 43 supports the display screen 3; and the thickness of the touch screen 2 and the height of the second protrusion 43 are both higher than the height of the first protrusion 42, so that a gap is formed between the outer side surface of the touch screen 2 and the inner side surface of the second protrusion 43, and the gap is filled with a sealing member 5, which forms a certain shielding to ensure that the display screen 3 has a waterproof and dustproof function. There is no specific limitation on the sealing member 5, for example, it can be a rubber ring, a silicone pad or other flexible material, and fixed between the support boss 4 and the touch screen 2 by snapping or interference pressing; it can also be a sealant with its own adhesiveness such as glass glue or foam glue. It is worth mentioning that the display screen 3 and the touch screen 2 can be physically connected using a flexible printed circuit board (FPC) to provide stable signal transmission and power supply.

[0044] In the embodiments of the present invention, please refer to Figures 2 to 4The touch display device 100 also includes a shielding layer 6, which is provided between the touch screen 2 and the display screen 3 to shield the electromagnetic signals emitted by the display screen 3. The shielding layer 6 can be a metal mesh structure, such as a mesh structure woven from stainless steel wire or copper wire, and the weaving density of the metal mesh can be adjusted according to the requirements of the shielding effect. Generally speaking, a high-density metal mesh can provide a better shielding effect. The metal mesh can be fixed between the touch screen 2 and the display screen 3 by adhesion, clamping or embedding to ensure good contact between the metal mesh and the display screen 3 and the touch screen 2 to achieve effective shielding. By providing a shielding layer 6 between the touch screen 2 and the display screen 3, the interference of the electromagnetic signal emitted by the display screen 3 on the touch screen 2 can be effectively reduced, thereby improving the accuracy and stability of the touch operation.

[0045] In the embodiments of the present invention, please refer to Figure 3 The perimeter of shielding layer 6 overlaps the surface of support boss 4 facing away from housing 1. That is, the outer perimeter of shielding layer 6 is larger than the outer perimeter of touch screen 2 to completely cover touch screen 2. This creates direct contact between shielding layer 6 and housing 1, forming a grounding connection that directs shielded electromagnetic signals to the ground, preventing interference with other components within the device. Overlapping shielding layer 6 on the surface of support boss 4 facing away from housing 1 ensures a good electrical connection between shielding layer 6 and housing 1, effectively blocking the intrusion of external electromagnetic waves and the leakage of internal electromagnetic waves, enhancing the overall shielding effect and improving the device's electromagnetic compatibility (EMC).

[0046] In the embodiments of the present invention, please refer to Figures 2 to 4 The touch display device 100 further includes a conductive adhesive layer 7, which is disposed on the side of the shielding layer 6 facing the display screen 3 and is located at the periphery of the shielding layer 6. The conductive adhesive layer 7 can be made of conductive foam, which is typically a composite of a conductive material (such as metal powder or conductive fiber) and a foam material, and has excellent conductivity and flexibility. The conductive foam is adhered to the exposed conductive surface of the electromagnetic shielding layer 6 in a circumferential manner, making close contact with the housing 1 to achieve conductive overlap, ensuring a good electrical connection between the shielding layer 6 and the housing 1, and effectively shielding against electromagnetic interference.

[0047] In the embodiments of the present invention, please refer to Figure 3, a positioning portion 41 is convexly provided on the surface of the support boss 4 facing away from the shell 1, and the positioning portion 41 abuts against the periphery of the shielding layer 6. One or more raised positioning portions 41 are provided on the surface of the support boss 4 facing away from the shell 1. These positioning portions 41 can be simple protrusions or structures with specific shapes (such as grooves, snaps, etc.) to ensure that the periphery of the shielding layer 6 can accurately match and abut therewith. It should be noted that the periphery of the shielding layer 6 is set to a shape that matches the positioning portion 41. For example, if the positioning portion 41 is convex, the periphery of the shielding layer 6 can be set to a groove shape so as to be tightly combined with the positioning portion 41. The support boss 4 can be an annular boss made of plastic or metal, and a series of raised positioning portions 41 are provided on the surface facing away from the shell 1. The shielding layer 6 can be a metal foil or a metal mesh, and its periphery is designed to be in the shape of a groove that matches the positioning portion 41. During assembly, the shielding layer 6 only needs to be placed on the supporting boss 4 , and the periphery of the groove of the shielding layer 6 will be automatically aligned with and fixed to the raised positioning portion 41 , thereby achieving accurate and fast assembly.

[0048] In the embodiments of the present invention, please refer to Figure 5 and Figure 6 Multiple positioning portions 41 are provided at intervals along the circumference of the support boss 4. This allows for a more even distribution of contact pressure between the shielding layer 6 and the support boss 4, reducing localized stress concentration. Furthermore, these positioning portions 41 provide multiple fixing points, enhancing the stability of the fixing between the shielding layer 6 and the support boss 4 and reducing displacement of the shielding layer 6 due to vibration or impact. Optionally, one of the multiple positioning portions 41 may be configured as a fool-proof design—that is, it may have a different shape from the other positioning portions 41—to facilitate quick and precise installation of the display screen 3.

[0049] In the embodiments of the present invention, please refer to Figure 3 and Figure 4 The touch screen 2 is bonded to the mounting groove 11 by an adhesive. The adhesive can be epoxy resin, acrylic glue or silicone, etc. These adhesives have good bonding strength, temperature resistance and aging resistance. The use of adhesives can reduce the use of mechanical connectors, reduce complex mechanical fixing or welding steps, simplify the manufacturing process, and improve production efficiency. In other embodiments, the adhesive can also be double-sided foam glue 8. In this way, it is only necessary to stick the double-sided foam glue 8 on the surface of the touch screen 2 or the inner wall of the mounting groove 11, and then place the touch screen 2 in the mounting groove 11. Press gently to ensure that the foam glue is in full contact with the two bonding surfaces, and a firm bond can be formed, thereby ensuring the stability and shock resistance of the touch screen 2 and improving the waterproof and dustproof performance of the device.

[0050] The present invention further provides a computer including a touch display device 100.
