Description

Technical Field

[0001] The utility model relates to the technical field of display panels, and particularly to a display panel and a mobile terminal thereof. Background Art

[0002] A display panel is the main interface for a mobile terminal to interact with users. It can present various images, texts, videos and other information, enabling users to intuitively obtain the required content. Among them, in the display panel, the display screen and the main control board are mainly connected. The main control board is connected to the display screen through specific interfaces (such as flexible cables, connectors, etc.) to transmit image data, control signals and power supplies, etc. This connection ensures that the main control board can control and drive the display screen to display images and content normally. Various electronic components, such as chips, transistors, capacitors, etc., are integrated on the main control board. When current passes through these components, certain resistance losses will be generated, which are converted into heat. In addition, the main control board will also perform data processing and operations during operation, which will also cause energy consumption and heat generation.

[0003] Therefore, heat dissipation fins are usually used to connect with the main control board to export the heat generated by the main control board. However, the size of the heat dissipation fins is different from the size of the accommodation space in the mobile terminal. Therefore, in the limited accommodation space, the installation quantity of the heat dissipation fins is fixed, so the heat dissipation effect of the heat dissipation fins is limited.

[0026] The following is combined with Figures 1 to 3 , and the display panel and its mobile terminal 100 provided by the embodiments of the present application are described in detail through specific embodiments.

[0027] Please refer to Figures 1 to 3 , Figure 1 which is a schematic structural diagram of the display panel provided by the present utility model; Figure 2 which is a front view of the display panel provided by the present utility model; Figure 3 which is a schematic structural diagram of the heat dissipation fins provided by the present utility model. The display panel and its mobile terminal 100 provided by one embodiment of the present utility model include a display screen 10, a main control board 20 and heat dissipation fins 30. The main control board 20 is electrically connected to the display screen 10; the heat dissipation fins 30 are connected to the main control board 20; wherein, the heat dissipation fins 30 include a heat conduction plate 31, a first heat dissipation part 32 and a second heat dissipation part 33, the first heat dissipation part 32 is horizontally arranged on the heat conduction plate 31 in a transverse direction, and the second heat dissipation part 33 is obliquely arranged on the heat conduction plate 31.

[0028] The first heat dissipation part 32 arranged horizontally can increase the contact area with air, which is beneficial to heat dissipation. The second heat dissipation part 33 arranged obliquely can further increase the heat dissipation area and can guide the air flow to enhance the heat dissipation effect. Through such an arrangement, a larger heat dissipation surface area can be provided within a limited space, thereby improving the heat dissipation efficiency. The heat generated by the main control board 20 can be effectively dissipated, maintaining the normal operating temperature of the display panel and improving its reliability and stability.

[0029] Moreover, by arranging the second heat dissipation part 33 obliquely on the heat conduction plate 31, the second heat dissipation part 33 and the first heat dissipation part 32 can be arranged in a square shape, so that the overall heat dissipation fins 30 are arranged in a square shape, which can save the installation space while providing a larger heat dissipation surface area, enabling the heat dissipation fins 30 to be installed in the mobile terminal.

[0030] In some embodiments, the first heat dissipation part 32 includes first heat dissipation fins 321, and a plurality of first heat dissipation fins 321 are arranged horizontally on the heat conduction plate 31.

[0031] During operation, the heat generated by the main control board 20 is transferred to the first heat dissipation fins 321 through the heat conduction plate 31, and the first heat dissipation fins 321 dissipate the heat into the surrounding environment. Air can exchange heat with the heat dissipation fins through natural convection or forced convection to take away the heat. In this way, the temperature of the display panel can be effectively reduced to ensure its normal operation. The horizontally arranged first heat dissipation fins 321 can be in full contact with air, increasing the heat dissipation surface area, which is beneficial to heat dissipation. The arrangement of a plurality of first heat dissipation fins 321 can increase the heat dissipation path, enabling the heat to be transferred to the heat dissipation fins more quickly and then dissipated into the surrounding environment. The distribution of a plurality of first heat dissipation fins 321 can make the heat more evenly distributed on the heat dissipation fins, avoiding local overheating, thereby improving the temperature uniformity of the entire display panel.

[0032] In some embodiments, the second heat dissipation part 33 includes second heat dissipation fins 332, and a plurality of second heat dissipation fins 332 are arranged obliquely on the heat conduction plate 31 and the ends of the plurality of second heat dissipation fins 332 are located on the same horizontal plane, and the first heat dissipation fins 321 and the second heat dissipation fins 332 together form a square shape.

[0033] Among them, the second heat dissipation fins 332 are arranged obliquely on the heat conduction plate 31, so as to increase the heat dissipation area of the second heat dissipation fins 332, and the ends of the second heat dissipation fins 332 are located on the same horizontal plane, enabling the overall heat dissipation fins 30 to be arranged in a square shape. Through such an arrangement, the heat dissipation area of the heat dissipation fins 30 can be increased within a limited installation space, thereby improving the heat dissipation effect of the heat dissipation fins 30.

[0034] In some embodiments, the second heat dissipation part 33 further includes a connecting plate 331. The connecting plate 331 is connected to the heat conducting plate 31 and is arranged at an angle with the heat conducting plate 31; the second heat dissipation fins 332 are arranged on both sides of the connecting plate 331.

[0035] The connecting plate 331 is located on the heat conducting plate 31. The heat conducting plate 31 can transfer the heat generated by the main control board 20 to the connecting plate 331. Then the connecting plate 331 can transfer the heat to the second heat dissipation fins 332, and the heat is dissipated to the outside air through the second heat dissipation fins 332. The connecting plate 331 is arranged at an angle with the heat conducting plate 31, which enables more second heat dissipation fins 332 to be connected to the connecting plate 331, thereby increasing the number of the second heat dissipation fins 332.

[0036] In some embodiments, the second heat dissipation fins 332 are arranged at an angle with the connecting plate 331. The second heat dissipation fins 332 are arranged on both sides of the connecting plate 331 and are inclined with the connecting plate 331, which can increase the number of the second heat dissipation fins 332 and increase the contact area between the second heat dissipation fins 332 and the air.

[0037] It should be noted that the ends of several second heat dissipation fins 332 are on the same horizontal plane, so that the overall shape of the heat dissipation fins 30 is square.

[0038] Another embodiment of the present invention further provides a mobile terminal, which includes the above-mentioned display panel. The first heat dissipation part 32 arranged horizontally can increase the contact area with the air, which is beneficial to heat dissipation. The second heat dissipation part 33 arranged obliquely can further increase the heat dissipation area and can guide the air flow to enhance the heat dissipation effect. Through such an arrangement, a larger heat dissipation surface area can be provided in a limited space, thereby improving the heat dissipation efficiency. The heat generated by the main control board 20 can be effectively dissipated, the normal working temperature of the display panel can be maintained, and its reliability and stability can be improved.

[0039] Moreover, by arranging the second heat dissipation part 33 obliquely on the heat conducting plate 31, the second heat dissipation part 33 and the first heat dissipation part 32 can be arranged in a square shape, so that the overall shape of the heat dissipation fins 30 is square, which can save the installation space while providing a larger heat dissipation surface area, and enables the heat dissipation fins 30 to be installed in the mobile terminal. It includes a display screen 10, a main control board 20 and heat dissipation fins 30. The main control board 20 is electrically connected to the display screen 10; the heat dissipation fins 30 are connected to the main control board 20; wherein, the heat dissipation fins 30 include a heat conducting plate 31, a first heat dissipation part 32 and a second heat dissipation part 33. The first heat dissipation part 32 is arranged horizontally on the heat conducting plate 31, and the second heat dissipation part 33 is arranged obliquely on the heat conducting plate 31.

[0040] The first heat dissipation part 32 arranged horizontally can increase the contact area with air, which is beneficial to heat dissipation. The second heat dissipation part 33 arranged obliquely can further increase the heat dissipation area and can guide the air flow to enhance the heat dissipation effect. Through such an arrangement, a larger heat dissipation surface area can be provided within a limited space, thereby improving the heat dissipation efficiency. The heat generated by the main control board 20 can be effectively dissipated, maintaining the normal operating temperature of the display panel and improving its reliability and stability.

[0041] Moreover, by arranging the second heat dissipation part 33 obliquely on the heat conduction plate 31, the second heat dissipation part 33 and the first heat dissipation part 32 can be arranged in a square shape, so that the overall heat dissipation fins 30 are arranged in a square shape, which can save the installation space while providing a larger heat dissipation surface area, enabling the heat dissipation fins 30 to be installed in the mobile terminal.

[0042] In some embodiments, the first heat dissipation part 32 includes first heat dissipation fins 321, and a plurality of first heat dissipation fins 321 are arranged horizontally on the heat conduction plate 31.

[0043] During operation, the heat generated by the main control board 20 is transferred to the first heat dissipation fins 321 through the heat conduction plate 31, and the first heat dissipation fins 321 dissipate the heat into the surrounding environment. Air can exchange heat with the heat dissipation fins through natural convection or forced convection to take away the heat. In this way, the temperature of the display panel can be effectively reduced to ensure its normal operation. The first heat dissipation fins 321 arranged horizontally can be in full contact with air, increasing the heat dissipation surface area, which is beneficial to heat dissipation. The arrangement of a plurality of first heat dissipation fins 321 can increase the heat dissipation path, enabling the heat to be transferred to the heat dissipation fins more quickly and then dissipated into the surrounding environment. The distribution of a plurality of first heat dissipation fins 321 can make the heat more evenly distributed on the heat dissipation fins, avoiding local overheating, thereby improving the temperature uniformity of the entire display panel.

[0044] In some embodiments, the second heat dissipation part 33 includes second heat dissipation fins 332, and a plurality of second heat dissipation fins 332 are arranged obliquely on the heat conduction plate 31 and the ends of the plurality of second heat dissipation fins 332 are located on the same horizontal plane, and the first heat dissipation fins 321 and the second heat dissipation fins 332 together form a square shape.

[0045] Among them, the second heat dissipation fins 332 are arranged obliquely on the heat conduction plate 31, so as to increase the heat dissipation area of the second heat dissipation fins 332, and the ends of the second heat dissipation fins 332 are located on the same horizontal plane, which can make the overall heat dissipation fins 30 arranged in a square shape. Through such an arrangement, the heat dissipation area of the heat dissipation fins 30 can be increased within a limited installation space, thereby improving the heat dissipation effect of the heat dissipation fins 30.

[0046] In some embodiments, the second heat dissipation part 33 further includes a connecting plate 331. The connecting plate 331 is connected to the heat conducting plate 31 and is disposed at an angle to the heat conducting plate 31; the second heat dissipation fins 332 are disposed on both sides of the connecting plate 331.

[0047] The connecting plate 331 is located on the heat conducting plate 31. The heat conducting plate 31 can transfer the heat generated by the main control board 20 to the connecting plate 331. Then the connecting plate 331 can transfer the heat to the second heat dissipation fins 332, and the heat is dissipated to the external air through the second heat dissipation fins 332. The connecting plate 331 is disposed at an angle to the heat conducting plate 31, which enables more second heat dissipation fins 332 to be connected to the connecting plate 331, thereby increasing the number of the second heat dissipation fins 332.

[0048] In some embodiments, the second heat dissipation fins 332 are disposed at an angle to the connecting plate 331. The second heat dissipation fins 332 are disposed on both sides of the connecting plate 331 and are inclined to the connecting plate 331, which can increase the number of the second heat dissipation fins 332 and increase the contact area between the second heat dissipation fins 332 and the air.

[0049] It should be noted that the ends of several second heat dissipation fins 332 are on the same horizontal plane, so that the overall heat dissipation fins 30 are square-shaped.

[0050] Another embodiment of the present utility model further provides a mobile terminal, which includes the above-mentioned display panel. The first heat dissipation part 32 disposed horizontally can increase the contact area with the air, which is beneficial to heat dissipation. The second heat dissipation part 33 disposed obliquely can further increase the heat dissipation area and can guide the air flow to enhance the heat dissipation effect. Through such a setting, a larger heat dissipation surface area can be provided within a limited space, thereby improving the heat dissipation efficiency. The heat generated by the main control board 20 can be effectively dissipated, the normal operating temperature of the display panel can be maintained, and its reliability and stability can be improved.

[0051] Moreover, by obliquely disposing the second heat dissipation part 33 on the heat conducting plate 31, the second heat dissipation part 33 and the first heat dissipation part 32 can be square-shaped, so that the overall heat dissipation fins 30 are square-shaped, which can save the installation space while providing a larger heat dissipation surface area, and enables the heat dissipation fins 30 to be installed in the mobile terminal.
