Description

Technical Field

[0001] This utility model relates to the field of display screens, and in particular to a liquid crystal display module. Background Technology

[0002] Traditional LCD modules generally adopt a rectangular design, and their backlight structure usually integrates auxiliary alignment structures such as brackets or positioning bosses to achieve precise positioning of the backlight and LCD components using mechanical limits.

[0003] Specifically, patent document CN202421274885.X discloses a liquid crystal display module and electronic device, which includes: an upper iron frame, a FOG glass assembly, a middle frame, a backlight, and a lower aluminum alloy die-cast part; the lower aluminum alloy die-cast part is used to support the backlight, and the back of the lower aluminum alloy die-cast part has a hollow structure; the middle frame is used to fix the backlight film and support the FOG glass assembly; the lower aluminum alloy die-cast part connects the middle frame and the upper iron frame by a snap fastener.

[0004] The aforementioned patent documents disclose positioning schemes for the backlight and LCD components, but these schemes can only be used for some fixed shapes, and have limitations for irregularly shaped displays. Specifically:

[0005] In scenarios requiring irregularly shaped displays (such as smart wearable devices), the display module needs to achieve a flush fit between the backlight and the LCD's dimensions. In this case, a backlight without a bezel is used to eliminate structural interference, but this removes crucial mechanical positioning features. This results in a lack of lateral constraint between components, increasing the likelihood of interlayer slippage due to shear stress during subsequent bonding. This misalignment leads to bonding misalignment and affects assembly efficiency.

[0006] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] This utility model uses a limiting structure to limit the backlight panel and the display panel, so that the two will not be misaligned and cause bonding misalignment. Specifically, when the backlight panel and the display panel are bonded together, the limiting structure will limit the backlight panel and the display panel along a direction parallel to the bonding surface, so that the two will not move relative to each other.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0042] As described in the background section, in scenarios requiring irregularly shaped displays (such as smart wearable devices), the display module needs to achieve a flush fit between the backlight and the LCD's dimensions. In this case, a backlight without a stop arm is used to eliminate structural interference, but this removes crucial mechanical positioning features. This results in a lack of lateral constraint between components, increasing the likelihood of interlayer slippage due to shear stress during subsequent bonding. This misalignment leads to bonding misalignment and affects assembly efficiency.

[0043] To solve this technical problem, this utility model provides a liquid crystal display module.

[0044] For details, please refer to Figures 1-7 The liquid crystal display module includes a backlight panel 1 and a display panel 2;

[0045] Along the thickness direction of the liquid crystal display module, the backlight panel 1 and the display panel 2 are arranged sequentially from right to left;

[0046] The backlight panel 1 and the display panel 2 are bonded together, and a bonding surface 3 is formed between them;

[0047] It also includes a limiting structure 4, which is disposed on the bonding surface 3. When the backlight panel 1 and the display panel 2 are bonded together, the limiting structure 4 is configured to limit the backlight panel 1 and the display panel 2 along a direction parallel to the bonding surface 3.

[0048] This utility model can limit the backlight panel 1 and the display panel 2 through the limiting structure 4, so that the two will not be misaligned and cause the bonding offset problem. Specifically, when the backlight panel 1 and the display panel 2 are bonded together, the limiting structure 4 will limit the backlight panel 1 and the display panel 2 along the direction parallel to the bonding surface 3, so that the two will not have relative movement.

[0049] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0050] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0051] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0052] First Embodiment

[0053] The liquid crystal display module includes a backlight panel 1 and a display panel 2;

[0054] Along the thickness direction of the liquid crystal display module, the backlight panel 1 and the display panel 2 are arranged sequentially from right to left;

[0055] The backlight panel 1 and the display panel 2 are bonded together, and a bonding surface 3 is formed between them;

[0056] It also includes a limiting structure 4, which is disposed on the bonding surface 3. When the backlight panel 1 and the display panel 2 are bonded together, the limiting structure 4 is configured to limit the backlight panel 1 and the display panel 2 along a direction parallel to the bonding surface 3.

[0057] This utility model can limit the backlight panel 1 and the display panel 2 through the limiting structure 4, so that the two will not be misaligned and cause the bonding offset problem. Specifically, when the backlight panel 1 and the display panel 2 are bonded together, the limiting structure 4 will limit the backlight panel 1 and the display panel 2 along the direction parallel to the bonding surface 3, so that the two will not have relative movement.

[0058] Preferably, the limiting structure 4 includes a limiting arm 5 and a limiting slot 6 corresponding to the limiting arm 5;

[0059] Of the backlight panel 1 and the display panel 2, the limiting arm 5 is provided protruding from the periphery of the surface of one of them, and the limiting slot 6 is provided recessed from the surface of the other.

[0060] When the backlight panel 1 and the display panel 2 are attached to each other, the limiting arm 5 is configured to be inserted into the limiting slot 6.

[0061] The limiting arm 5 may be set on the backlight panel 1 or the display panel 2, and in the case of irregular display requirements, at least three limiting arms 5 must be set to achieve the limiting operation.

[0062] When the limiting arm 5 is inserted into the limiting slot 6, the backlight panel 1 and the display panel 2 will not move relative to each other in a direction parallel to the bonding surface 3.

[0063] Preferably, the limiting arm 5 is disposed on the surface of the backlight panel 1 near the display panel 2;

[0064] Taking the bonding surface 3 as a reference, the inside of the bonding surface 3 is the inner side, and the outside of the bonding surface 3 is the outer side;

[0065] The outer wall of the limiting arm 5 is flush with the periphery of the backlight panel 1.

[0066] The limiting slot 6 is located on the periphery of the display panel 2.

[0067] Since the display panel 2 is typically attached to the backlight panel 1, the limiting arm 5 is positioned on a stationary component, namely the backlight panel 1, to prevent damage. Furthermore, the area on the display panel 2 corresponding to the bonding surface 3 occupies only a large portion of the display panel 2, leaving some area outside the backlight panel 1. Therefore, if the limiting arm 5 extends beyond the edge of the backlight panel 1, it may obstruct installation space during subsequent display module assembly.

[0068] Preferably, the backlight panel 1 has a polygonal structure, and the limiting arm 5 is disposed at the corner of the polygonal structure surface;

[0069] The inner wall of the limiting arm 5 is a horizontal plane.

[0070] The corner is set to facilitate the determination of the position of the limit arm 5.

[0071] Preferably, the height of the limiting arm 5 is less than or equal to the height of the display panel 2.

[0072] The above design ensures that the limiting arm 5 will not be too high, thus preventing the entire module from being fixed.

[0073] Second Embodiment

[0074] The liquid crystal display module provided in Embodiment 1 is further optimized by providing a positioning structure on the limiting arm 5. The positioning structure is disposed on the inner side of the limiting arm 5 to guide the backlight panel 1 and the display panel 2 to fit together.

[0075] When the backlight panel 1 and the display panel 2 are attached, the limiting slot 6 on the display panel 2 may not be fully aligned with the limiting arm 5 before the display panel 2 is pressed against the backlight panel 1. In order to solve this problem, a positioning structure is used to guide the backlight panel 1 and the display panel 2 to attach to each other.

[0076] Preferably, the positioning structure is a limiting protrusion 7 disposed inside the limiting arm 5;

[0077] The bottom of the limiting slot 6 is provided with a guide groove 8 at the position corresponding to the limiting protrusion 7; the shape of the guide groove 8 is matched with that of the limiting protrusion 7.

[0078] Preferably, the guide groove 8 and the limiting protrusion 7 are in clearance fit.

[0079] Specifically, the limiting protrusion 7 and the guide groove 8 are fitted together to ensure that the limiting slot 6 can be fully aligned with the limiting arm 5.

[0080] Subsequently, when the backlight panel 1 and the display panel 2 are attached to each other, the limiting protrusion 7 can play a guiding role.

[0081] Third Embodiment

[0082] The limiting arm 5 is provided with a positioning structure, which is located on the inner side of the limiting arm 5 to guide the backlight panel 1 and the display panel 2 to fit together.

[0083] When the backlight panel 1 and the display panel 2 are attached, the limiting slot 6 on the display panel 2 may not be fully aligned with the limiting arm 5 before the display panel 2 is pressed against the backlight panel 1. In order to solve this problem, a positioning structure is used to guide the backlight panel 1 and the display panel 2 to attach to each other.

[0084] Preferably, the positioning structure consists of two limiting blocks 9 disposed inside the limiting arm 5. When viewed from a cross-sectional perspective, the two limiting blocks 9 are symmetrically disposed at both ends of the limiting arm 5.

[0085] The bottom of the limiting slot 6 is provided with a limiting slot 10 at the position corresponding to the limiting slot block 9, and the width of the limiting slot 10 is greater than that of the limiting slot block 9.

[0086] In Embodiment 2, there is a phenomenon where the limiting protrusion 7 bumps into the display panel 2. Therefore, two limiting locking blocks 9 are used for alignment. The distance between the two limiting locking blocks 9 is greater than the distance between the two limiting slots 10.

[0087] Preferably, a ventilated groove 11 is provided at the junction of the inner side wall of the limiting arm 5 and the bottom of the limiting slot 6.

[0088] After the inner wall of the limiting arm 5 is attached to the bottom of the limiting groove 6, the high smoothness will cause an adsorption phenomenon, making it difficult for the inner wall of the limiting arm 5 to slide between the bottom of the limiting groove 6. The venting groove 11 is there to allow gas to enter and reduce adsorption.

[0089] The process of using the liquid crystal display module provided by this utility model is as follows: This utility model can limit the backlight panel 1 and the display panel 2 through the limiting structure 4, so that the two will not be misaligned and cause the bonding offset problem. Specifically, when the backlight panel 1 and the display panel 2 are bonded to each other, the limiting structure 4 will limit the backlight panel 1 and the display panel 2 along the direction parallel to the bonding surface 3, so that the two will not have relative movement.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
