Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid crystal display module technology, specifically to a liquid crystal display module with an anti-blue light and explosion-proof structure. Background Technology
[0002] The liquid crystal display module is the display component of a monitor. The principle of liquid crystal display is that the backlight assembly emits uniform surface light, which is transmitted through the liquid crystal screen to our eyes to form an image.
[0003] Most LCD display modules currently on the market are similar in overall structure, consisting mainly of components such as backlight, polarizing filter, TFT substrate, and color filter substrate. However, they have some functional shortcomings in actual use and have room for improvement. For example, few current LCD display modules address blue light, and some models have simple coatings. The mainstream methods for preventing blue light are mainly two: absorption, which is achieved by adding blue light blocking factors to the glass substrate, and interception, which is achieved by coating the glass surface. There is still room for improvement in the effectiveness of blue light protection, and they do not have multiple blue light protection functions.
[0004] Therefore, a novel blue light-proof and explosion-proof liquid crystal display module is proposed to solve the above problems. Utility Model Content
[0005] To address the aforementioned problems, the purpose of this utility model is to provide a liquid crystal display module with an anti-blue light and explosion-proof structure, thereby solving the problem mentioned in the background art of not having multiple anti-blue light functions.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A liquid crystal display module with a blue light protection and explosion-proof structure, comprising:
[0008] LCD display module;
[0009] A first frame covers the front of the liquid crystal display module;
[0010] The anti-blue light factor substrate glass is installed within the first frame;
[0011] A blue light blocking coating is applied to one side surface of a blue light blocking factor substrate glass back-side liquid crystal display module.
[0012] Preferably, the liquid crystal display module has a module housing.
[0013] The first frame has an adhesive on the side facing the liquid crystal display module, and the first frame is bonded to the module housing by the adhesive.
[0014] Preferably, the liquid crystal display module includes a backlight, a first polarizer, an FT substrate, a color filter substrate, and a second polarizer arranged sequentially from back to front.
[0015] Preferably, the outer casing of the module is provided with a perforated buffer groove at the corresponding corner, and the first frame is provided with a rod pre-reserved hole at the corresponding buffer groove.
[0016] The front of the first frame has an impact-resistant component in the form of a frame plate, and the back corner of the impact-resistant component has an extension rod corresponding to the buffer groove. The extension rod passes through a reserved hole and is inserted into the buffer groove.
[0017] Preferably, the end of the extension rod has a piston head that engages with the inner wall of the buffer groove.
[0018] Preferably, the bottom of the buffer groove has a first magnet, and the end of the extension rod has a second magnet, with the opposite magnetic poles of the first and second magnets being the same.
[0019] Preferably, the impact-resistant component includes a frame-type outer frame plate, the interior of which is fitted with tempered glass.
[0020] Preferably, the module housing is fixedly mounted on the main fixing plate. The main fixing plate is provided with rubber strips on the left and right sides facing the module housing. Plastic heads are glued to the upper and lower ends of the rubber strips, and fixing screws are inserted into the front ends of the plastic heads.
[0021] Preferably, the fixing screw passes through the plastic head and extends into the interior of the main fixing plate, and the rubber band is elastic.
[0022] Preferably, the front end face of the anti-blue light coating is flush with the front end face of the first frame, and the anti-blue light coating and the anti-blue light factor substrate glass have the same shape.
[0023] The beneficial effects of using this utility model are:
[0024] (1) By setting a first frame, an anti-blue light coating, an anti-blue light factor substrate glass, an adhesive, and a rod pre-reserved hole, when in use, the backlight, the first polarizer, the TFT substrate, the color filter substrate, and the second polarizer constitute the main body of the liquid crystal display module. During the display process, the anti-blue light factor added to the anti-blue light factor substrate glass in the first frame can absorb blue light and reduce the outward emission of blue light. The anti-blue light coating acts as a second interception to further reduce the leakage of blue light. The adhesive facilitates the installation and fixation of the first frame, and the rod pre-reserved hole provides space for the front and rear movement of the extension rod, thus realizing multiple anti-blue light functions.
[0025] (2) By setting up a buffer groove, a first magnet, an outer frame plate, tempered glass, an extension rod, a piston head and a second magnet, when in use, the outer protective barrier formed by the outer frame plate and the tempered glass can protect the components behind it. When an external force hits, the outer frame plate and the tempered glass move backward under the force, and the piston head behind the extension rod moves backward along the buffer groove. The air in the buffer groove is compressed to offset the impact. When the external force disappears, the piston head resets under the action of air pressure. The first magnet and the second magnet serve as the second guarantee for reset, thus realizing the functions of anti-smashing and anti-explosion.
[0026] (3) With rubber band, plastic head and fixing screw, the main fixing plate is fixed in the housing of the LCD display when in use. When disassembling, first remove the screw at the main board fixing hole, then hold the rubber band and pull it outward to remove the display module. The plastic head and fixing screw provide physical support for the installation and fixing of the rubber band, realizing the function of easy disassembly and lifting. Attached Figure Description

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.
[0033] Example 1: Please refer to Figure 1-4A liquid crystal display module with an anti-blue light and explosion-proof structure includes a main fixing plate 1, a module housing 2 fixedly connected to the front end of the main fixing plate 1, a backlight 3 fixedly connected to the rear end inside the module housing 2, a TFT substrate 5 disposed in front of the backlight 3, a first polarizer 4 fixedly connected between the backlight 3 and the TFT substrate 5, a color filter substrate 6 fixedly connected to the front end of the TFT substrate 5, a second polarizer 7 fixedly connected to the front end of the color filter substrate 6, main board fixing holes 20 respectively opened at the four corners of the front end of the main fixing plate 1, an external wiring 24 movably connected to the bottom end of the module housing 2, a connector 25 disposed at the bottom end of the external wiring 24, and an anti-blue light component that can reduce blue light disposed at the front end of the module housing 2.
[0034] Please see Figure 1-4 A liquid crystal display module with an anti-blue light and explosion-proof structure also includes an anti-blue light component. The anti-blue light component includes a first frame 8, which is fixedly connected to the front end of the module housing 2. An anti-blue light factor substrate glass 10 is fixedly connected inside the first frame 8. An anti-blue light coating 9 is coated on the front end of the anti-blue light factor substrate glass 10. Rod pre-reserved holes 12 are respectively opened at the four corners of the front end of the first frame 8. Adhesive 11 is coated on the left and right sides and the top and bottom ends of the rear end of the first frame 8.
[0035] The rear ends of the first frame 8 and the anti-blue light factor substrate glass 10 are flush. The upper and lower ends and the left and right sides of the first frame 8 are flush with the upper and lower ends and the left and right sides of the module housing 2, respectively. The front end of the anti-blue light coating 9 is flush with the front end of the first frame 8. The anti-blue light coating 9 and the anti-blue light factor substrate glass 10 have the same shape. The rear end of the adhesive 11 is tightly attached to the front end of the module housing 2. The pre-drilled holes 12 of the rods are symmetrically distributed about the vertical center line of the first frame 8, providing multiple layers of anti-blue light protection.
[0036] Specifically, such as Figure 1 and Figure 4 As shown, the blue light blocking factor added to the blue light blocking factor substrate glass 10 in the first frame 8 can absorb blue light and reduce the outward emission of blue light. The blue light blocking coating 9 acts as a second interception to further reduce the leakage of blue light. The adhesive 11 facilitates the installation and fixation of the first frame 8. The pre-drilled hole 12 of the rod provides space for the front and rear movement of the extension rod 17.
[0037] Example 2: Buffer grooves 13 are respectively provided at the four corners of the front end of the module housing 2. A first magnet 14 is fixedly connected to the rear end of the buffer groove 13. An outer frame plate 15 is provided at the front of the module housing 2. Tempered glass 16 is fixedly connected inside the outer frame plate 15. Extension rods 17 are fixedly connected to the four corners of the rear end of the outer frame plate 15. A piston head 18 is glued to the rear end of the extension rod 17. A second magnet 19 is fixedly connected to the rear end of the piston head 18. The outer diameter of the piston head 18 matches the inner diameter of the buffer groove 13. The piston head 18 can move back and forth along the interior of the buffer groove 13. The magnetic poles of the opposite faces of the first magnet 14 and the second magnet 19 are the same, providing impact and explosion protection. ；
[0038] Specifically, such as Figure 2 and Figure 3 As shown, when an external force strikes, the outer frame plate 15 and tempered glass 16 are pushed backward by the force, and the piston head 18 behind the extension rod 17 moves backward along the buffer groove 13. The air in the buffer groove 13 is compressed to offset the impact. When the external force disappears, the piston head 18 returns to its original position under the action of air pressure. The first magnet 14 and the second magnet 19 serve as a second guarantee for the return to its original position. 。
[0039] Example 3: Rubber strips 21 are respectively provided on both sides of the front end of the main fixing plate 1. Plastic heads 22 are glued to the upper and lower ends of the rubber strips 21 respectively. Fixing screws 23 are inserted into the front end of the plastic heads 22. The fixing screws 23 pass through the plastic heads 22 and extend into the interior of the main fixing plate 1. The rubber strips 21 are elastic, making it easy to remove the entire module. ；
[0040] Specifically, such as Figure 1 As shown, remove the screws at the motherboard mounting hole 20, then pull the rubber band 21 outwards to remove the display module. The plastic head 22 and the fixing screw 23 provide physical support for the installation and fixation of the rubber band 21. 。
[0041] Working Principle: In use, the backlight 3, first polarizer 4, TFT substrate 5, color filter substrate 6, and second polarizer 7 constitute the main body of the liquid crystal display module. During the display process, the blue light blocking factor added to the blue light blocking factor substrate glass 10 in the first frame 8 can absorb blue light and reduce its outward emission. The blue light blocking coating 9 acts as a second layer of interception, further reducing blue light leakage. The adhesive 11 facilitates the installation and fixation of the first frame 8, and the pre-drilled hole 12 on the rod provides space for the forward and backward movement of the extension rod 17. The outer protective barrier formed by the outer frame plate 15 and tempered glass 16 can protect the components behind it. When an external force strikes, the outer frame plate 15 and tempered glass 16 move backward under the force, and the piston head 18 behind the extension rod 17 moves backward along the buffer groove 13. The air in the buffer groove 13 is compressed to offset the impact. When the external force disappears, the piston head 18 resets under the action of air pressure. The first magnet 14 and the second magnet 19 serve as a second layer of protection for reset. The main mounting plate 1 is fixed inside the housing of the LCD monitor. When disassembling, first remove the screws at the main mounting hole 20, then pull the rubber band 21 outward to remove the display module. The plastic head 22 and the fixing screw 23 provide physical support for the installation and fixation of the rubber band 21.
