Description

Technical Field

[0001] The present invention relates to the technical field of liquid crystal display modules, and specifically to a liquid crystal display module with a light leakage prevention function. Background Technique

[0002] A liquid crystal display module is a liquid crystal display screen and a backlight assembly installed in its housing. The light leakage phenomenon of a liquid crystal display module generally occurs when there is light around the display area against a black background, which affects the display effect and color accuracy. Such a situation is generally caused by an increase in the usage time or equipment aging.

[0003] According to a disclosed liquid crystal display module with light leakage prevention (Publication No.: CN218886351U), in the above application, moving the light-shielding strip upward can avoid blocking the display screen of the liquid crystal display module body. When it is necessary to shield the liquid crystal display module body from light, moving the light-shielding strip downward can block the light leakage of the liquid crystal display module body. It is possible to decide whether to shield the liquid crystal display module body according to the brightness of the surrounding ambient light, without affecting the normal picture display of the liquid crystal display module.

[0004] However, during the actual use of the above device, it is necessary to add a light-shielding baffle around the outside of the display module. The final light-shielding effect for preventing light leakage is achieved by a silica gel sleeve attached to the periphery of the display screen to achieve a closed and fitting effect and a light-shielding strip on its surface. However, as the usage time increases, the silica gel sleeve and the light-shielding strip pasted on the display screen surface will experience phenomena such as glue opening and separation due to aging and thermal expansion and contraction, which will easily lead to light scattering and light leakage around the display screen, affecting people's normal viewing experience. In view of this, we have proposed a liquid crystal display module with a light leakage prevention function. Summary of the Invention

[0005] The purpose of the present invention is to provide a liquid crystal display module with a light leakage prevention function to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A liquid crystal display module with a light leakage prevention function includes a housing. A silica gel sheath is fixedly installed on the inner wall of the side of the housing. A docking groove is opened at the center of the silica gel sheath. A display screen is arranged inside the docking groove. A positioning component is arranged inside the silica gel sheath to tightly press the edge of the contact part between the silica gel sheath and the display screen. An adjustment component is arranged inside the silica gel sheath to assist in repairing the glue opening between the silica gel sheath and the display screen.

[0007] Preferably, the positioning component includes a filling cavity which is formed on the inner wall of the silica gel sheath. A positioning tube is fixedly installed on the inner wall of the filling cavity. An annular arc-shaped groove is formed on the inner wall of the docking groove close to the display screen side. A positioning ring is fixedly installed on the side wall of the display screen. An annular T-shaped groove is formed on the inner wall of the docking groove close to the display screen side. A T-shaped ring is fixedly installed on the side wall of the display screen. A partition is fixedly installed on the inner surface of the filling cavity.

[0008] Preferably, the size of the annular arc-shaped groove is adapted to that of the positioning ring. The side of the annular arc-shaped groove close to the filling cavity is made of flexible silica gel material, so that when the positioning ring enters the annular arc-shaped groove, it can compress the flexible silica gel material. The arc-shaped outer surface of the positioning ring is rough, so that the positioning ring can maintain a more stable state after entering the annular arc-shaped groove.

[0009] Preferably, the cross-section of the T-shaped ring is T-shaped, and the size of the T-shaped ring is adapted to that of the annular T-shaped groove, so that when the silica gel sheath is docked and installed with the display screen, the T-shaped ring can be completely embedded into the annular T-shaped groove. The T-shaped ring includes a vertical part installed on the outer surface of the display screen and a flat part fixedly installed on the side of the vertical part. Through the limitation of the flat part of the T-shaped ring and the annular T-shaped groove, when the surface between the silica gel sheath and the display screen is delaminated or cracked, it can limit this part to prevent it from delaminating too much.

[0010] Preferably, several groups of partitions are provided, and several groups of partitions are arranged at equal intervals inside the filling cavity to form several small cavities with similar spaces inside the filling cavity, so that the protection of the silica gel sheath is carried out in units of each small cavity.

[0011] Preferably, the adjustment component includes an air hole which is formed on the outer wall of the silica gel sheath far from the housing. An air replenishing valve is fixedly installed inside the air hole. A positioning frame is fixedly installed on the side wall of the partition. A silica gel membrane is fixedly installed on the inner surface of the positioning frame. A bending block is movably installed on the side wall of the partition. A contact strip is fixedly installed on the arc-shaped outer wall of the positioning tube. A pressing strip is fixedly installed on the arc-shaped outer wall of the positioning tube.

[0012] Preferably, several groups of air holes and air replenishing valves are provided, and several groups of air holes and air replenishing valves are arranged in the area between two adjacent partitions, so that air replenishment can be achieved in each of the several small cavities separated by several partitions inside the filling cavity. The bending block includes an installation strip and a movable arc strip, and the movable arc strip is attached to the side surface of the silica gel membrane. Thus, when the air pressure in the small cavity rises, the air pressure forces the silica gel membrane to deform, and then promotes it to generate a driving force on the attached movable arc strip.

[0013] Preferably, the contact strip and the pressing strip are respectively arranged on the corresponding left and right sides of the arc-shaped outer wall of the positioning tube. The contact strip is arranged on the side close to the bending block, while the pressing strip is arranged on the side close to the contact part between the silica gel sheath and the display screen. The user can inflate the air supplement valve at the air hole corresponding to the glue opening position, so as to prompt the pressing strip to press the contact part between the silica gel sheath and the display screen, so as to ensure the close contact between the silica gel sheath and the display screen.

[0014] Preferably, a deformation component for enhancing the gripping force of the T-shaped ring is arranged inside the silica gel sheath. The deformation component includes an air extraction valve. The air extraction valve is fixedly installed on the inner wall of the silica gel sheath close to the display screen side. An L-shaped cavity is opened on the inner wall of the silica gel sheath. The L-shaped cavity is opened on the side of the T-shaped ring close to the center of the display screen, and the L-shaped cavity is arranged to be adapted to the T-shaped ring. The air extraction valve is connected to the L-shaped cavity in a through manner. The air in the L-shaped cavity is extracted, and then under the action of the external atmospheric pressure, the L-shaped cavity is oppressed, and the part of the silica gel sheath around the L-shaped cavity generates a pulling force on the T-shaped ring.

[0015] Preferably, a glue filling component for facilitating the adsorption and gripping between the silica gel sheath and the display screen is arranged inside the docking groove. The glue filling component includes an annular square groove. The annular square groove is opened on the inner surface of the docking groove close to the front side of the display screen. A silica gel column is fixedly installed on the bottom inner surface of the annular square groove. The number of the annular square grooves is set to two groups, and the two groups of annular square grooves are arranged in a form of large in small. The number of the silica gel columns is set to several, and several silica gel columns are arranged at equal intervals. The silica gel columns arranged in the two groups of annular square grooves are arranged at intervals, so as to improve the anti-glue opening ability of the edge of the silica gel sheath.

[0016] Compared with the prior art, the present invention provides a liquid crystal display module with a light leakage prevention function, and has the following beneficial effects:

[0017] 1. For the liquid crystal display module with the light leakage prevention function, by setting a positioning component and cooperating with the settings of the annular T-shaped groove and the T-shaped ring, when the contact part between the silica gel sheath and the display screen accidentally opens the glue, it is restricted to a certain extent, avoiding the situation of excessive glue opening, which directly affects the wrapping and protection effect of the silica gel sheath on the edge of the display screen. At the same time, through the setting of a plurality of partition plates, the overall shape of the filling cavity is maintained. At the same time, the restriction of the end part of the partition plate on the positioning tube enables the positioning tube to ensure the tight state of the contact part between the silica gel sheath and the display screen, reducing the possibility of light leakage around the display screen and improving the overall use effect of the display module.

[0018] 2. The liquid crystal display module with a light leakage prevention function is provided with an adjustment component. When the bonding at the contact part between the silicone sheath and the display screen comes off, resulting in light leakage in the display module, the user can inflate the air inlet valve at the air hole corresponding to the bonding position, so that the small cavity corresponding to this position expands, and then the silicone film is pressed and deformed. By the contact and extrusion of the silicone film on the bending block, the movable arc bar deflects to generate an extrusion effect on the contact strip. At this time, under the thrust in the tangential direction of the outer arc wall of the positioning tube by the contact strip, the pressing strip presses the contact part between the silicone sheath and the display screen to ensure the close contact between the silicone sheath and the display screen, avoid the excessive expansion of the bonding area and affect the light leakage prevention effect of the display screen, and improve the user experience of the display module.

[0019] 3. The liquid crystal display module with a light leakage prevention function is provided with a deformation component. The air in the L-shaped cavity is pumped out by the cooperation of the air extraction pump and the air extraction valve, and then under the action of the external atmospheric pressure, the L-shaped cavity is compressed. The silicone sheath part around the L-shaped cavity generates a pulling force on the T-shaped ring, so as to make the annular T-shaped groove fit more tightly on the T-shaped ring, improve the gripping degree of the connection between the silicone sheath and the display screen, avoid the influence of local bonding of the silicone sheath on other positions, and then improve the light leakage prevention performance of the display module.

[0020] 4. The liquid crystal display module with a light leakage prevention function is provided with a glue filling component. The silicone columns arranged in the two groups of annular square grooves are arranged at intervals. When the silicone sheath and the display screen are docked and installed, the inside of the annular square groove is filled with sealant. Through the silicone columns arranged at intervals, the filling thickness of the sealant at different positions is different. With the air extraction effect of the deformation component on the L-shaped cavity, the edge of the silicone sheath is uneven, so as to improve the anti-bonding ability of the edge of the silicone sheath, avoid the problem that one point of bonding affects multiple places, and then affect the overall light leakage prevention performance of the silicone sheath.

[0033] As Figures 1 - 11 shown, the present invention provides a technical solution: A liquid crystal display module with a light leakage prevention function, including a housing 1, a silicone sheath 2 is fixedly installed on the inner wall of the side surface of the housing 1, a docking groove 4 is opened at the center of the silicone sheath 2, a display screen 3 is arranged inside the docking groove 4, and a positioning component 5 for pressing against the edge of the contact part between the silicone sheath 2 and the display screen 3 is arranged inside the silicone sheath 2. The positioning component 5 includes a filling cavity 51, a positioning tube 52, a ring-shaped arc groove 53, a positioning ring 54, a ring-shaped T-shaped groove 55, a T-shaped ring 56 and a partition board 57.

[0034] In an embodiment of the present invention, a filling cavity 51 is formed in the inner wall of the silica gel sheath 2. A positioning tube 52 is fixedly installed on the inner wall of the filling cavity 51. An annular arc-shaped groove 53 is formed in the inner wall of the docking groove 4 close to one side of the display screen 3. A positioning ring 54 is fixedly installed on the side wall of the display screen 3. An annular T-shaped groove 55 is formed in the inner wall of the docking groove 4 close to one side of the display screen 3. A T-shaped ring 56 is fixedly installed on the side wall of the display screen 3. A partition 57 is fixedly installed on the inner surface of the filling cavity 51.

[0035] Furthermore, an installation cavity for accommodating the display screen 3 and the silica gel sheath 2 is formed in the side wall of the housing 1. The size of the display screen 3 is adapted to that of the docking groove 4, facilitating the staff to completely sleeved the silica gel sheath 2 outside the display screen 3, so that stable protection can be obtained around the display screen 3. At the same time, the silica gel sheath 2 is made of a metal plate wrapped with silica gel, ensuring the edge protection effect and light leakage prevention effect of the silica gel sheath 2 on the display screen 3 while maintaining the overall shape of the silica gel sheath 2. In addition, the end cross-section of the silica gel sheath 2 is U-shaped to better adapt to the wrapping requirement of the outer edge of the display screen 3. Specifically, the positioning tube 52 is solid and is arranged in the inner cavity of the filling cavity 51 close to the center of the display screen 3 to strengthen the contact edge between the silica gel sheath 2 and the display screen 3.

[0036] Meanwhile, the size of the annular arc-shaped groove 53 is adapted to that of the positioning ring 54. When the display screen 3 is installed inside the docking groove 4, the docking of the positioning ring 54 and the annular arc-shaped groove 53 ensures the accuracy of the position of the display screen 3 in the docking groove 4, preventing the display screen 3 from being skewed or offset, which may affect the display effect of the entire display module. Further, the side of the annular arc-shaped groove 53 close to the filling cavity 51 is made of flexible silica gel material, so that when the positioning ring 54 enters the annular arc-shaped groove 53, it can compress the flexible silica gel material, making the fit between the positioning ring 54 and the annular arc-shaped groove 53 closer. At the same time, the arc-shaped outer surface of the positioning ring 54 is rough, so that the positioning ring 54 can maintain a more stable state after entering the annular arc-shaped groove 53, preventing the positioning ring 54 from shifting relative to the silica gel sheath 2 and ensuring the installation stability of the display screen 3.

[0037] Specifically, the cross-section of the T-shaped ring 56 is T-shaped, and the size of the T-shaped ring 56 is adapted to the size of the annular T-shaped groove 55, so that when the silicone sheath 2 is docked and installed with the display screen 3, the T-shaped ring 56 can be completely embedded into the annular T-shaped groove 55. The T-shaped ring 56 includes a vertical portion installed on the outer surface of the display screen 3 and a flat portion fixedly installed on the side of the vertical portion. Specifically, through the restriction of the flat portion of the T-shaped ring 56 and the annular T-shaped groove 55, when the glue opens or a slit appears between the surface of the silicone sheath 2 and the display screen 3, the situation can be restricted at this part to avoid excessive glue opening, which directly affects the wrapping and protection effect of the silicone sheath 2 on the edge of the display screen 3. Further, the T-shaped ring 56 is arranged on one side of the positioning ring 54 close to the center of the display screen 3, and the T-shaped ring 56 is closer to the edge of the silicone sheath 2 to better provide a restricting and protecting effect for the silicone sheath 2.

[0038] In addition, several groups of partition plates 57 are provided, and the several groups of partition plates 57 are arranged at equal intervals inside the filling cavity 51 to form several small cavities with similar spaces inside the filling cavity 51, so that the protection of the silicone sheath 2 is carried out in units of each small cavity. If the phenomenon of glue opening or light leakage occurs, small-scale repair can be carried out in time without replacing the entire silicone sheath 2, reducing the cost of subsequent use and maintenance of the display module. At the same time, the length of the partition plate 57 is less than the width of the filling cavity 51, so as to leave enough installation space for the positioning tube 52 to maintain the overall shape of the filling cavity 51 and the tight state of the contact part between the silicone sheath 2 and the display screen 3, reducing the possibility of light leakage around the display screen 3 and improving the overall use effect of the display module.

[0039] Further, an adjustment component 6 for assisting in repairing the glue opening between the silicone sheath 2 and the display screen 3 is arranged inside the silicone sheath 2. The adjustment component 6 includes an air hole 61, the air hole 61 is opened on the outer wall of the silicone sheath 2 away from the housing 1, an air supply valve 62 is fixedly installed inside the air hole 61, a positioning frame 63 is fixedly installed on the side wall of the partition plate 57, a silicone film 64 is fixedly installed on the inner surface of the positioning frame 63, a bending block 65 is movably installed on the side wall of the partition plate 57, a contact strip 66 is fixedly installed on the arc-shaped outer wall of the positioning tube 52, and a pressing strip 67 is fixedly installed on the arc-shaped outer wall of the positioning tube 52.

[0040] Specifically, there are several groups of the number settings of the air holes 61 and the air replenishing valves 62, and several groups of the air holes 61 and the air replenishing valves 62 are arranged in the area between two adjacent partition plates 57, so that the air replenishing effect can be achieved for several small cavities separated by several partition plates 57 in the filling cavity 51. Moreover, the air replenishing valve 62 is made of a one-way valve and is connected to the air replenishing valve 62 through relevant air replenishing equipment to inflate the above-mentioned small cavities, so that the small cavities are in a full state. In addition, the top and bottom of the positioning frame 63 are fixedly connected to the mutually close side surfaces of two adjacent groups of partition plates 57 respectively, so as to completely seal the small cavities. At the same time, several positioning frames 63 achieve the effect of sealing the small cavities one by one, so that the air pressure of the corresponding small cavities can be increased when inflating the small cavities, and it will not have a greater impact on the small cavities in other parts. At the same time, the silica gel film 64 is arranged in a film shape, and the silica gel film 64 itself can generate a certain amount of deformation, so that after the air pressure in the small cavity is increased, affected by the air pressure, the silica gel film 64 itself will generate a certain amount of deformation.

[0041] At the same time, the bending block 65 includes a mounting strip and a movable arc strip, and the movable arc strip is attached to the side surface of the silica gel film 64. Thus, when the air pressure in the small cavity rises, the air pressure forces the silica gel film 64 to deform, and then promotes it to generate a driving force on the movable arc strip attached to the surface, so as to drive the movable arc strip to move towards the positioning tube 52. Further, the bending block 65 is arranged between two adjacent groups of partition plates 57, so that each group of small cavities corresponds to a group of bending blocks 65, which is convenient for the user to perform more precise maintenance work on the silica gel sheath 2. In addition, the contact strip 66 and the pressing strip 67 are respectively arranged on the corresponding left and right sides of the arc-shaped outer wall of the positioning tube 52, and the contact strip 66 is arranged on the side close to the bending block 65, while the pressing strip 67 is arranged close to the contact part between the silica gel sheath 2 and the display screen 3. When the contact part between the silica gel sheath 2 and the display screen 3 is unsealed and the display module has a light leakage phenomenon, the user can inflate the air replenishing valve 62 at the air hole 61 corresponding to the unsealed position, so that the small cavity corresponding to this position expands, and then promotes the silica gel film 64 to be deformed by pressure. Through the touch and extrusion of the silica gel film 64 on the bending block 65, the movable arc strip performs a deflection movement and then generates an extrusion effect on the contact strip 66. At this time, under the thrust of the contact strip 66 in the tangential direction on the arc-shaped outer wall of the positioning tube 52, the pressing strip 67 presses the contact part between the silica gel sheath 2 and the display screen 3, so as to ensure the close contact between the silica gel sheath 2 and the display screen 3, and avoid the unsealed area from expanding too much and affecting the light leakage prevention effect of the display screen 3, and improve the use experience of the display module.

[0042] Specifically, a deformation component 7 for enhancing the gripping force of the T-shaped ring 56 is provided inside the silica gel sheath 2. The deformation component 7 includes an air extraction valve 71. The air extraction valve 71 is fixedly installed on the inner wall of the silica gel sheath 2 on the side close to the display screen 3. An L-shaped cavity 72 is formed on the inner wall of the silica gel sheath 2. Specifically, the number of the deformation components 7 is set to four groups, and the four groups of deformation components 7 are respectively arranged inside the four sides of the frame-shaped silica gel sheath 2. At the same time, the L-shaped cavity 72 is formed on the side of the T-shaped ring 56 close to the center of the display screen 3, and the setting of the L-shaped cavity 72 is adapted to the T-shaped ring 56. It should be noted that the air extraction valve 71 is connected to the L-shaped cavity 72 in a through manner. After the docking installation between the display screen 3 and the silica gel sheath 2 is completed, the air extraction pump and the air extraction valve 71 cooperate with each other to extract the air in the L-shaped cavity 72. Then, under the action of the external atmospheric pressure, the L-shaped cavity 72 is compressed, and the part of the silica gel sheath 2 around the L-shaped cavity 72 generates a pulling force on the T-shaped ring 56, so as to make the annular T-shaped groove 55 fit more tightly on the T-shaped ring 56, improve the gripping degree at the connection between the silica gel sheath 2 and the display screen 3, avoid the influence of local glue opening of the silica gel sheath 2 on other positions, and further improve the light leakage prevention performance of the display module.

[0043] In the embodiment of the present invention, a glue filling component 8 for facilitating the adsorption and gripping between the silica gel sheath 2 and the display screen 3 is provided inside the docking groove 4. The glue filling component 8 includes an annular square groove 81. The annular square groove 81 is formed on the inner surface of the docking groove 4 on the side close to the front of the display screen 3. A silica gel column 82 is fixedly installed on the inner surface of the bottom of the annular square groove 81. Specifically, the number of the annular square grooves 81 is set to two groups, and the two groups of annular square grooves 81 are arranged in a large-in-small form. Specifically, one group of annular square grooves 81 is arranged outside the other group of annular square grooves 81, and the two groups of annular square grooves 81 are concentrically arranged. At the same time, the number of the silica gel columns 82 is set to several, and the several silica gel columns 82 are arranged at equal intervals. The silica gel columns 82 arranged in the two groups of annular square grooves 81 are arranged at intervals. When the silica gel sheath 2 and the display screen 3 are docked and installed, the annular square groove 81 is filled with sealant. Through the silica gel columns 82 arranged at intervals, the filling thickness of the sealant at different positions is different. Cooperating with the air extraction action of the deformation component 7 on the L-shaped cavity 72, the edge of the silica gel sheath 2 is made to be uneven, so as to improve the anti-glue-opening ability of the edge of the silica gel sheath 2, avoid the problem that a little glue opening affects multiple places, and further affect the overall light leakage prevention performance of the silica gel sheath 2.

[0044] In the present invention, during use, the display screen 3 is docked with the docking groove 4, so that the positioning ring 54 is docked with the annular arc-shaped groove 53, and at the same time, the T-shaped ring 56 is docked and installed with the annular T-shaped groove 55, so that the silica gel sheath 2 is completely sleeved outside the display screen 3. Then, a sufficient amount of sealant is filled inside the annular square groove 81, and the air in the L-shaped cavity 72 is pumped out through the cooperation of the air pump and the air extraction valve 71. After the sealant is cured, it is ensured that the silica gel sheath 2 seals and wraps the edge of the display screen 3 to avoid the occurrence of glue opening and light leakage at the edge of the display screen 3. Then, the display screen 3 is docked and installed with the housing 1. During the use of the display module, by providing an adjustment component 6, when glue opening occurs somewhere between the silica gel sheath 2 and the display screen 3, the user inflates the air supply valve 62 at the air hole 61 corresponding to the glue opening position, so that the small cavity corresponding to this position expands, and then the silica gel film 64 is pressed and deformed. By the touch and extrusion of the silica gel film 64 on the bending block 65, the movable arc bar deflects to generate an extrusion effect on the contact strip 66. At this time, under the tangential thrust of the contact strip 66 on the arc-shaped outer wall of the positioning tube 52, the pressing strip 67 presses the contact part between the silica gel sheath 2 and the display screen 3 to ensure the close contact between the silica gel sheath 2 and the display screen 3 and avoid the expansion of the glue opening area being too large and affecting the light leakage prevention effect of the display screen 3.

[0045] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, any modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
