[0002] Liquid crystal display is a type of flat panel display. It is used for screen display of television and computer. The advantages of this display are low power consumption, small size and low radiation. Liquid crystal display uses liquid crystal solution in two polarized materials. When current passes through the liquid, the crystals will be rearranged to achieve the purpose of imaging. Therefore, it is very popular among home users and is suitable for electronic devices using batteries.

[0003] The metal clip PIN of the existing display screen is connected to the driver IC. Since the driver IC requires more signal pins, the number of metal clip PINs is also correspondingly large.

When welding, it is easy to cause solder short circuit between adjacent metal PINs. Utility Model Content

[0004] Based on this, it is necessary to provide a metal clip PIN for a liquid crystal display screen to address the above technical problems. The first PIN and the second PIN of the liquid crystal display screen are designed in two shapes, and the first PIN and the second PIN are arranged alternately according to odd and even numbers, so that the odd-numbered PINs and the even-numbered PINs form two rows. In this way, the spacing between adjacent metal clip PINs in the odd-numbered rows and the even-numbered rows is increased, effectively avoiding the solder short-circuit phenomenon between adjacent metal clip PINs.

[0024] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0025] As in the background art, the metal clip PIN of the liquid crystal display screen is designed by designing the first PIN7 and the second PIN8 of the liquid crystal display screen into two shapes, and the first PIN7 and the second PIN8 are arranged alternately according to odd and even numbers, so that the odd-numbered PINs and the even-numbered PINs form two rows, thereby increasing the spacing between adjacent metal clip PIN6 in the odd-numbered row and the even-numbered row, and effectively avoiding the solder short-circuit phenomenon of adjacent metal clip PIN6.

[0026] In order to solve this technical problem, the utility model provides a metal clip PIN for a liquid crystal display screen, which increases the spacing between adjacent metal clip PINs 6 so that odd-numbered PINs and even-numbered PINs form two rows.

[0027] Specifically, please refer to Figure 1-5 , the display screen design specifically includes:

[0028] An upper polarizer 1, an upper glass 2, a lower glass 3, a lower polarizer 4 and a driver IC 5, the upper glass 2 and the lower glass 3 are fixedly connected, the upper polarizer 1 is fixedly connected to the upper surface of the upper glass 2, the lower polarizer 4 is fixedly connected to the lower surface of the lower glass 3, and the driver IC 5 is installed on the right side of the lower glass 3;

[0029] Metal clip PIN6, the metal clip PIN6 is installed on the right side of the lower glass 3, the metal clip PIN6 includes a plurality of first PIN7 and second PIN8 arranged alternately, the first PIN7 includes a first connecting portion 701 and a first vertical portion 702 connected in sequence, the second PIN8 includes a second connecting portion 801, a second vertical portion 802, an inclined portion 803 and a third vertical portion 804 connected in sequence.

[0030] The metal clip PIN of the liquid crystal display screen provided by the utility model is used to install multiple first PIN7 and second PIN8 of the metal clip PIN6 on the main board. At this time, the anti-skid pad 19 on the positioning plate 11 contacts the main board, and then the adjusting screw 16 is rotated by using a tool. Since the bottom end of the adjusting screw 16 is threadedly connected with the threaded barrel 13, the slider 17 on the positioning plate 11 can slide in the slide groove 18 on the connecting rod 12. At this time, the adjusting screw 16 can drive the threaded barrel 13 and the positioning plate 11 to move upward during the rotation, so that the positioning plate 11 moves toward the connecting rod 12 and the heat sink 9, reducing the overall height, so that the first PIN7 and the second PIN8 extend to a suitable length, which can be freely adjusted as needed, so that the display screen is more stable when the first PIN7 and the second PIN8 are welded;

[0031] The metal clip PIN6 is a tin-plated metal with a copper substrate and a nickel base. One end with a clamp is connected to the LCD display screen, and the other end is soldered to the mainboard. The first PIN7 and the second PIN8 of the LCD display screen are designed in two shapes, and the first PIN7 and the second PIN8 are staggered according to odd and even numbers, so that the odd-numbered PINs and the even-numbered PINs form two rows. In this way, the spacing between adjacent metal clip PIN6 in the odd-numbered row and the even-numbered row is increased, effectively avoiding the solder short circuit phenomenon of adjacent metal clip PIN6;

[0032] After welding, the metal clip PIN6 can also be fixed to the mainboard through the mounting hole 20 on the positioning plate 11, so that the display screen and the mainboard are firmly fixed together to prevent vibration. When working, the heat of the display is transferred to the heat sink 9 and the heat sink fins 10, thereby preventing the temperature of the display from being too high and improving the service life.

[0033] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0036] Example 1

[0037] Please refer to Figure 1-5 A metal clip PIN for a liquid crystal display screen comprises an upper polarizer 1, an upper glass 2, a lower glass 3, a lower polarizer 4 and a driver IC 5, wherein the upper glass 2 and the lower glass 3 are fixedly connected, the upper polarizer 1 is fixedly connected to the upper surface of the upper glass 2, the lower polarizer 4 is fixedly connected to the lower surface of the lower glass 3, and the driver IC 5 is installed on the right side of the lower glass 3;

[0038] The metal clip PIN6 is installed on the right side of the lower glass 3. The metal clip PIN6 includes a plurality of first PIN7 and second PIN8 arranged alternately with each other. The first PIN7 includes a first connecting portion 701 and a first vertical portion 702 connected in sequence. The second PIN8 includes a second connecting portion 801, a second vertical portion 802, an inclined portion 803 and a third vertical portion 804 connected in sequence. The metal clip PIN6 is a tin-plated metal with a copper substrate and a nickel base. One end with a clamp is connected to the LCD display screen, and the other end is welded to the main board. The first PIN7 and the second PIN8 of the liquid crystal display screen are designed in two shapes, and the first PIN7 and the second PIN8 are arranged alternately according to odd and even numbers, so that the odd PINs and the even PINs form two rows, thereby increasing the spacing between adjacent metal clip PIN6 in the odd row and the even row.

[0039] Please refer to Figure 1 and 3 The bottom end of the first vertical portion 702 is parallel to the bottom end of the third vertical portion 804 , and the bottom end of the inclined portion 803 is inclined toward a side away from the lower glass 3 .

[0040] In this way, the overall heights of the first PIN 7 and the second PIN 8 are equal, and the lengths extended when welding a main board are equal. At the same time, the bottom end of the inclined portion 803 is inclined toward the side away from the lower glass 3 to facilitate welding of the first PIN 7 and the second PIN 8.

[0041] Please refer to Figure 1 and Figure 5 A heat sink 9 is fixedly connected to the lower surface of the lower polarizer 4, a plurality of heat sink fins 10 are fixedly connected to the lower surface of the heat sink 9, and positioning plates 11 are provided on both the front and rear sides of the lower surface of the heat sink 9 through up and down adjustment components.

[0042] The display screen provided in this embodiment transfers the heat of the display screen to the heat sink 9 and the heat sink fins 10 when the display screen is in operation, thereby preventing the temperature of the display screen from being too high and increasing the service life.

[0043] Example 2

[0044] The display screen provided in Example 1 is further optimized, specifically, as follows: Figure 1-3 As shown, the up and down adjustment assembly includes a connecting rod 12 fixedly connected to the front and rear sides of the lower surface of the heat sink 9, the positioning plate 11 is slidably connected to the connecting rod 12, a threaded tube 13 is fixedly connected to the middle of the upper surface of the positioning plate 11, a groove 14 is provided in the middle of the upper surface of the connecting rod 12, and an avoidance groove 15 corresponding to the groove 14 is provided on the heat sink 9. An adjusting screw 16 is rotatably connected inside the groove 14, and the bottom end of the adjusting screw 16 passes through the connecting rod 12 and is threadedly connected to the threaded tube 13.

[0045] Through the above structural design, when in use, multiple first PIN7 and second PIN8 of the metal clip PIN6 are installed on the main board. At this time, the anti-slip pad 19 on the positioning plate 11 is in contact with the main board, and then the adjusting screw 16 is rotated using a tool. Since the bottom end of the adjusting screw 16 is threadedly connected to the threaded barrel 13, and the slider 17 on the positioning plate 11 can slide in the slide groove 18 on the connecting rod 12, the adjusting screw 16 can drive the threaded barrel 13 and the positioning plate 11 to move upward during the rotation, so that the positioning plate 11 moves toward the connecting rod 12 and the heat sink 9, lowering the overall height, so that the first PIN7 and the second PIN8 extend to a suitable length, which can be freely adjusted as needed, so that the display screen is more stable when welding the first PIN7 and the second PIN8.

[0046] Example 3

[0047] The display screen provided in Example 1 or 2 is further optimized, such as Figure 1 and Figure 3 As shown, the left and right sides of the upper surface of the positioning plate 11 are fixedly connected with sliders 17, and the left and right sides of the connecting rod 12 are provided with slide grooves 18, and the sliders 17 are slidably connected in the slide grooves 18;

[0048] The slider 17 on the positioning plate 11 is arranged in this way so that it can slide in the slide groove 18 on the connecting rod 12, so that the positioning plate 11 can move up and down more stably and avoid tilting.

[0049] Example 4

[0050] The display screen provided in the above embodiments is further optimized, such as Figure 2 and Figure 4 As shown, the lower surface of the positioning plate 11 is fixedly connected with an anti-skid pad 19, and the anti-skid pad 19 is made of rubber;

[0051] When used in this setting, multiple first PIN7 and second PIN8 of the metal clip PIN6 are installed on the main board. At this time, the anti-skid pad 19 on the positioning plate 11 contacts the main board. The rubber valve anti-skid pad 19 increases the friction between the positioning plate 11 and the main board to prevent sliding.

[0052] The display screen provided in the above embodiments is further optimized, such as Figure 3 As shown, the length of the positioning plate 11 is greater than the length of the connecting rod 12 , and mounting holes 20 are provided on both the left and right sides of the positioning plate 11 .

[0053] With such a structural design, the metal clip PIN 6 can be fixed to the mainboard through the mounting hole 20 on the positioning plate 11 after welding, so that the display screen and the mainboard are firmly fixed together to prevent vibration.

[0054] The use process of the display screen provided by the utility model is as follows:

[0055] When in use, install multiple first PIN7 and second PIN8 of the metal clip PIN6 on the main board. At this time, the anti-skid pad 19 on the positioning plate 11 contacts the main board. Then use a tool to rotate the adjusting screw 16. Since the bottom end of the adjusting screw 16 is threadedly connected to the threaded barrel 13, the slider 17 on the positioning plate 11 can slide in the slide groove 18 on the connecting rod 12. At this time, the adjusting screw 16 can drive the threaded barrel 13 and the positioning plate 11 to move upward during the rotation, so that the positioning plate 11 moves toward the connecting rod 12 and the heat sink 9, lowering the overall height, so that the first PIN7 and the second PIN8 extend to a suitable length, which can be freely adjusted as needed, so that the display screen is more stable when the first PIN7 and the second PIN8 are welded;

[0056] The metal clip PIN6 is a tin-plated metal with a copper substrate and a nickel base. One end with a clamp is connected to the LCD display screen, and the other end is soldered to the mainboard. The first PIN7 and the second PIN8 of the LCD display screen are designed in two shapes, and the first PIN7 and the second PIN8 are staggered according to odd and even numbers, so that the odd-numbered PINs and the even-numbered PINs form two rows. In this way, the spacing between adjacent metal clip PIN6 in the odd-numbered row and the even-numbered row is increased, effectively avoiding the solder short circuit phenomenon of adjacent metal clip PIN6;

[0057] After welding, the metal clip PIN6 can also be fixed to the mainboard through the mounting hole 20 on the positioning plate 11, so that the display screen and the mainboard are firmly fixed together to prevent vibration. When working, the heat of the display is transferred to the heat sink 9 and the heat sink fins 10, thereby preventing the temperature of the display from being too high and improving the service life.
