[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0029] Please refer to Figures 1-4 , a heat-dissipating screen assembly, comprising an outer screen 1, a touch layer 2, a display layer 3, a backlight plate 4, a partition plate 5 and a wire 6;

[0030] Among them, the outer screen 1, the touch layer 2, the display layer 3, the backlight plate 4 and the partition plate 5 are arranged in order from top to bottom, the touch layer 2, the display layer 3 and the backlight plate 4 are all electrically connected with the wire 6, and the wire 6 is electrically connected with the device mainboard;

[0031] Specifically, the outer screen 1 is made of transparent glass, mainly serving to provide physical protection for the internal touch layer 2 and display layer 3. Below the outer screen 1 is the touch layer 2, which is bonded together with OCA adhesive. Below the touch layer 2 is the display layer 3. A polarizing layer is placed between the touch layer 2 and the display layer 3. The polarizing layer is bonded to the touch layer 2 with OCA adhesive on top and to the display layer 3 with polarizing adhesive on the bottom. Below the display layer 3, the backlight panel 4 is also bonded with polarizing adhesive. Finally, below the backlight panel 4 is a partition 5, which is a metal partition and provides electromagnetic shielding, reducing electromagnetic interference between the screen module and the internal components of the device, and also enhancing the overall mechanical strength of the module. The ribbon cable 6 branches out with wires (not shown in the diagram) that are electrically connected to the touch layer 2, display layer 3, and backlight panel 4 respectively. This allows the motherboard's display signals and current to be transmitted to the display layer 3 and backlight panel 4, and the user's touch feedback signals on the touch layer 2 to be transmitted to the motherboard, enabling interactive use of the screen.

[0032] It also includes a heat-conducting frame 7, which surrounds the upper edge of the partition 5 and wraps around the edges of the touch layer 2, the display layer 3 and the backlight panel 4. The upper side of the heat-conducting frame 7 is flush with the touch layer 2. The outer screen 1 covers the heat-conducting frame 7, and the outer screen 1 has a microporous structure 11 at the position corresponding to the heat-conducting frame 7 at the four edges of the outer screen 1.

[0033] Specifically, when the screen module is working, the heat-conducting frame 7, which wraps around the edges of the touch layer 2, display layer 3 and backlight panel 4, absorbs the generated heat. The outer screen 1 covers the heat-conducting frame 7, and the upper side of the heat-conducting frame 7 is in close contact with the outer screen 1, so that the heat is dissipated through the micro-hole structure 11 opened on the outer screen 1, forming an upward heat dissipation path, reducing the pressure on the internal heat dissipation system of the device, improving heat dissipation efficiency, and effectively controlling the temperature of the screen module during high-intensity use.

[0034] Meanwhile, the upper side of the heat-conducting frame 7 is flush with the touch layer 2, which avoids the formation of uneven structures between the heat-conducting frame 7 and the touch layer 2, allowing the outer screen 1 to completely adhere to the touch layer 2 and the heat-conducting frame 7, thus improving the bonding and fixing effect.

[0035] The heat-conducting frame 7 is made of heat-conducting materials, such as copper or graphite, which are not limited here.

[0036] Furthermore, the upper side of the heat-conducting frame 7 has a protruding structure 71 that interlocks with the microporous structure 11;

[0037] Specifically, the protruding structure 71 of the heat-conducting frame 7 is tightly fitted with the microporous structure 11, so that the surface of the protruding structure 71 of the heat-conducting frame 7 is exposed on the surface of the outer screen 1, which allows heat to dissipate better and the airflow can carry the dissipated heat better, thereby further improving the heat dissipation efficiency.

[0038] Furthermore, the convex structure 71 can also improve the waterproof performance after being embedded in the microporous structure 11, so as to prevent water from seeping into the microporous structure 11, and preferably, waterproof glue can be added when the outer screen 1 is bonded with the heat-conducting frame 7, so as to further improve the waterproof performance, so that the waterproof performance of the product can meet the daily use requirements.

[0039] Further, the edge of the outer screen 1 is flush with the edge of the heat-conducting frame 7, and the flush edge can better fit the interior of the equipment when the screen assembly is installed in the equipment, so as to prevent the occurrence of gaps.

[0040] Further, the heat-conducting frame 7 is provided with an opening 72 at a position corresponding to the flat cable 6, and the opening 72 is arranged in position with the flat cable 6, so as to ensure that the connection of the flat cable 6 is not affected.

[0041] Further, the outer screen 1 is provided with a silk-screen frame 8 around the edge, and the position of the silk-screen frame 8 corresponds to the heat-conducting frame 7.

[0042] Specifically, the silk-screen frame 8 is arranged around the edge of the outer screen 1 to cover the heat-conducting frame 7, so that the user cannot see the heat-conducting frame 7 through the outer screen 1, thereby improving the overall appearance.

[0043] In addition, the heat-conducting frame 7 is provided with a shock-absorbing sheet 9 at each corner.

[0044] Specifically, the shock-absorbing sheet 9 at each corner is used to protect the touch layer 2, the display layer 3 and the backlight plate 4, and specifically, when the equipment falls, the corners have a higher probability of being the impact point, and when the corners are impacted, the shock-absorbing sheet 9 can absorb the impact force during the impact, thereby reducing the risk of the touch layer 2, the display layer 3 and the backlight plate 4 being broken.

[0045] Specifically, the shock-absorbing sheet 9 at each corner is used to protect the touch layer 2, the display layer 3 and the backlight plate 4, and specifically, when the equipment falls, the corners have a higher probability of being the impact point, and when the corners are impacted, the shock-absorbing sheet 9 can absorb the impact force during the impact, thereby reducing the risk of the touch layer 2, the display layer 3 and the backlight plate 4 being broken.

[0046] Further, the shock-absorbing sheet 9 is arranged on the inner side of the heat-conducting frame 7 at each corner, and the touch layer 2, the display layer 3 and the backlight plate 4 are each provided with a position-allowing notch 10 corresponding to the shock-absorbing sheet 9.

[0047] Specifically, the shock-absorbing sheet 9 at each corner is used to protect the touch layer 2, the display layer 3 and the backlight plate 4, and specifically, when the equipment falls, the corners have a higher probability of being the impact point, and when the corners are impacted, the shock-absorbing sheet 9 can absorb the impact force during the impact, thereby reducing the risk of the touch layer 2, the display layer 3 and the backlight plate 4 being broken.

[0048] Specifically, the shock-absorbing sheet 9 at each corner is used to protect the touch layer 2, the display layer 3 and the backlight plate 4, and specifically, when the equipment falls, the corners have a higher probability of being the impact point, and when the corners are impacted, the shock-absorbing sheet 9 can absorb the impact force during the impact, thereby reducing the risk of the touch layer 2, the display layer 3 and the backlight plate 4 being broken.

[0049] In another embodiment, the shock pads 9 can also be arranged outside the four corners of the heat-conducting frame 7, and the outside of the four corners of the heat-conducting frame 7 is provided with clearance gaps 10 matching the shock pads 9, so as to ensure that the overall edge remains flat.
