Description

Technical Field

[0001] The utility model relates to the technical field of notebook computers, in particular to a display device and a terminal device. Background Technique

[0002] In the structure of a notebook computer, the outer shell plays a crucial role and is usually composed of an A shell, a B shell, a C shell, and a D shell. Among them, the A shell, that is, the top cover part we usually call, is located on the top layer when the notebook computer is in the closed state, and often has the brand logo of the manufacturer engraved on it, which not only shows the product identity but also plays a key role in protecting the internal screen from external physical damage. The B shell, also known as the B frame, is the core carrier of the visual interface of the notebook computer, closely surrounding the four edges of the liquid crystal display screen to form a support frame for the screen. The design of this area not only needs to consider aesthetics but also needs to take into account the structural stability and functional integrity.

[0003] In the current manufacturing process of notebook computers, the assembly process between the B shell and the display screen and the A shell is very crucial. Especially between the B shell and the display screen, the flatness of the bonding surface is given extremely high standards and requirements. This is because if the bonding surface fails to meet the expected flatness standard, it will directly affect the activation area of the adhesive on the B shell, and then potential problems will be exposed when tested in environments such as high temperature and high humidity, such as the phenomenon of glue opening. Such problems not only affect the overall aesthetics of the product but may also seriously damage the structural integrity and service life of the notebook computer. Therefore, strict control measures must be taken during the manufacturing process to ensure the absolute flatness and precise assembly of the B shell bonding surface.

[0004] The above information is given as background information only to assist in understanding the present disclosure, and does not determine or admit whether any of the above content can be used as the prior art relative to the present disclosure. Summary of the Utility Model

[0056] Embodiment 1

[0057] Please refer to Figure 1 , Figure 1Schematic diagram of the bonding structure between a display screen and a housing 1 in the prior art. Specifically, the housing 1 is directly pasted onto the optical component 2 and the tape 3 through the adhesive 6 on its back. Since there is a layer of sealant 4 (usually Tuffy glue, also known as blue glue) covering a set area of the optical component 2 (specifically, a single-layer area, that is, the non-multi-layer area of the optical component 2) to protect the IC (integrated circuit) in this set area. However, when the process of the sealant 4 is dispensing, since the sealant 4 is in a flowing liquid state, the surface tension of the liquid will cause the sealant 4 to form a wedge shape in height in this set area. This causes a depression on the surface of the tape 3 when the tape 3 is directly pasted on the surface of the sealant 4. Therefore, only a part of the adhesive 6 on the back of the housing 1 can be pasted onto the tape 3 to be activated, resulting in incomplete contact on the bonding surface and potential peeling risks, that is, the so-called "delamination" problem in the industry. This phenomenon not only affects the overall aesthetics of the product, but also poses a threat that cannot be ignored to its durability and stability.

[0058] To solve the above problems, please refer to Figure 2-3 , an embodiment of the present utility model provides a display device, including a display screen, an adhesive 6 and a housing 1; wherein,

[0059] The display screen includes an optical component 2, a tape 3, a sealant 4 and a spacer 5;

[0060] One side of the optical component 2 is provided with the sealant 4, the sealant 4 is wedge-shaped, and with its excellent sealing and protection performance, the sealant 4 provides a solid barrier for the area where it is located;

[0061] The tape 3 is arranged on the side of the sealant 4 away from the optical component 2;

[0062] The spacer 5 is arranged between the sealant 4 and the tape 3 to support the tape 3 and achieve the flattening of the tape 3;

[0063] The housing 1 is arranged between the housing 1 and the tape 3 and is flatly bonded to the housing 1 and the tape 3 respectively.

[0064] It should be noted that the difference between this embodiment and the prior art lies in the introduction of the innovative design of the spacer 5. Specifically, the spacer 5 is cleverly arranged between the sealant 4 and the tape 3. As a support structure, the spacer 5 ensures that it can completely fill the wedge height difference formed on the surface of the sealant 4. When the tape 3 is pasted on the spacer 5, due to the support of the spacer 5, the tape 3 can maintain a flat and non-depressed state. This design not only solves the problem of the unevenness of the tape 3 caused by the possible wedge height difference during the curing process of the sealant 4, but also greatly optimizes the overall flatness of the subsequent bonding surface.

[0065] When the housing 1 is firmly adhered to the surface of the precisely adjusted tape 3 through the adhesive 6, due to the presence of the spacer 5, the adhesive 6 can come into contact with the entire adhesive surface, thereby significantly increasing its activation area and effectively avoiding the phenomenon of glue separation caused by local non - adhesion.

[0066] In summary, compared with the prior art, in this embodiment, by introducing the innovative design of the spacer 5, not only is the adhesion problem caused by the shape of the sealant 4 fundamentally solved, but also the overall aesthetics, structural integrity and service life of the display device are greatly improved. This design innovation undoubtedly sets a new benchmark for technological progress and product upgrading in the field of display devices. Additionally, since there is no need for large - scale changes to the existing production process, it does not affect production costs and is easy to operate. Compared with other solutions that may require significant design or material adjustments, the material cost of this solution is also very low.

[0067] It can be understood that the spacer 5 can be made of PET (polyethylene terephthalate) or rubber as its main material. PET material is widely favored for its excellent mechanical properties, chemical stability and processing performance. It has high strength, hardness and heat resistance, and can maintain a stable form and performance in various environments. At the same time, PET material also has good light transmittance and insulation, which is particularly important for application scenarios that require avoiding electromagnetic interference or maintaining optical transparency.

[0068] On the other hand, rubber material is famous for its good elasticity and sealing performance. The rubber spacer 5 can deform when subjected to external extrusion, thereby filling the gaps or uneven surfaces formed due to the curing of the sealant 4. This self - adaptive filling ability helps to improve the tightness and sealing performance of the adhesive surface. In addition, rubber material also has a certain shock - absorbing effect, which can relieve the damage to the internal components of the display device caused by external impact or vibration.

[0069] In summary, whether it is PET or rubber material, both have their own unique advantages and characteristics. In practical applications, the appropriate material for the spacer 5 can be selected according to specific requirements and scenarios. For example, in cases where high strength, high hardness and good light transmittance are required, the PET spacer 5 may be a more suitable choice; while in cases where good elasticity, sealing performance and shock - absorbing effect are required, the rubber spacer 5 may be more advantageous. Through reasonable material selection and structural design, it can be ensured that the spacer 5 exhibits the best performance in the display device.

[0070] In one implementation of this embodiment, the structure of the sealant 4 is further refined. Specifically, the surface of the sealant 4 in contact with the optical component 2 is a flat surface, and this design ensures that the sealant 4 can closely and evenly adhere to the surface of the optical component 2, thereby effectively realizing the protection function for the IC below it. The surface of the sealant 4 in contact with the spacer 5 is an inclined surface due to the surface tension of the liquid.

[0071] In this embodiment, the shape of the spacer 5 is complementary to the shape of the sealant 4.

[0072] It should be noted that the shape and height of the spacer 5 are specially considered and designed to ensure a perfect complementary match with the wedge-shaped profile of the sealant 4, so as to be able to fill the wedge-shaped height difference formed on the surface of the sealant 4.

[0073] For this key component, the spacer 5, this embodiment provides diverse design ideas to meet the specific requirements in different application scenarios. The following is a detailed explanation of two typical design styles.

[0074] The first implementation: The spacer 5 is wedge-shaped;

[0075] Please refer to again Figure 2-3 , in this implementation, the spacer 5 is designed to be wedge-shaped. This design cleverly echoes the wedge shape of the sealant 4, achieving a perfect shape match. Specifically, the surface of the spacer 5 in contact with the tape 3 is designed to be a flat surface to ensure a tight fit with the tape 3 and provide stable support. The surface of the spacer 5 in contact with the sealant 4 is correspondingly an inclined surface, and this inclined surface is complementary to the inclined surface of the sealant 4, effectively filling the surface unevenness caused by the sealant 4 and creating ideal conditions for the subsequent bonding process.

[0076] The second implementation: The spacer 5 is stepped;

[0077] Please refer to Figure 4 , in this implementation, the spacer 5 adopts a stepped design. On the basis of keeping the surface in contact with the tape 3 as a flat surface, this design adapts to the inclined surface of the sealant 4 by introducing stepped surfaces. The stepped spacer 5 can not only compensate for the inclined surface of the sealant 4 in the vertical direction but also adjust the number of steps in the horizontal direction as needed to better fit the sealant 4 with different inclined surface lengths and / or angles. This flexible design enables the spacer 5 to be widely applied to various models of display devices, improving the product compatibility and adaptability.

[0078] In summary, whether the cushion block 5 is designed in a wedge shape or a stepped shape, it aims to optimize the flatness of the bonding interface by precisely complementary matching the shape of the sealant 4, thereby enhancing the bonding effect between the housing 1 and the display screen and avoiding the occurrence of glue separation. These designs not only improve the structural stability and durability of the display device but also provide users with a more reliable and lasting usage experience.

[0079] It can be understood that, on the one hand, when the cushion block 5 is designed in a wedge shape, this form requires the entire cushion block 5 to present a smooth transition that gradually inclines from one end to the other. To achieve this effect and ensure that the cushion block 5 can maintain stable structural strength and durability during use, an integrally molded technology is usually adopted for manufacturing. Integral molding can not only ensure the precision and uniformity of the shape of the cushion block 5 but also effectively avoid assembly errors or loosening problems that may be introduced by multi-component assembly, thereby further improving its fitting tightness and bonding effect with the sealant 4 and the tape 3.

[0080] On the other hand, when the cushion block 5 adopts a stepped design, its structure is more complex and variable. The stepped cushion block 5 may include at least two stacked gaskets, and the size of each gasket is different to adapt to the height difference existing in the inclined surface of the sealant 4. This segmented design endows the cushion block 5 with higher flexibility and adaptability, enabling it to precisely match the sealant 4 with various different inclined surface lengths and / or angles. At the same time, in order to ensure the stable combination between the stacked gaskets and the performance of the whole, precise processing techniques and reliable connection methods are usually used to process between the gaskets to ensure that the cushion block 5 can exhibit the best performance when serving as a compensation element for the bonding surface.

[0081] Please refer to Figure 3-4 again. In an implementation manner of this embodiment, the refined structure of the optical component 2 is particularly pointed out. Specifically, as an important component in the display device, the internal structure of the optical component 2 is carefully composed of multiple key components to achieve complex functions of image display and color management.

[0082] First, in the direction from close to the housing 1 to far from the housing 1, three key components, namely a polarizer 21, a CF glass 22, and a TFT glass 23, are sequentially arranged. The polarizer 21, as the outermost layer of the optical component 2, is mainly responsible for the polarization processing of light and is an important link to ensure the pure color and clear contrast of the display screen. Subsequently, the CF glass 22 (Color Filter Glass) follows closely. It contains precise color filter patterns inside and is used to separate white light into red, green, and blue primary color lights, thereby endowing the display screen with rich color expressiveness.

[0083] The innermost layer is the TFT glass 23 (Thin Film Transistor Glass). It is not only the carrier of the pixel array but also responsible for controlling the on / off of each pixel and adjusting the brightness. It is the key to achieving high definition and fast response speed. These three components are stacked in sequence from the direction close to the housing 1 to the direction away from the housing 1, and are tightly combined together through precise bonding and encapsulation processes, jointly constituting the complex and precise optical component 2 as a whole.

[0084] In addition, it is worth noting that in this embodiment, the arrangement order and relative positions between these three components have been carefully designed and optimized to ensure that light can propagate smoothly along the predetermined path and present the best display effect when finally reaching the user's eyes.

[0085] Please refer to Figure 3-4 again. In an implementation manner of this embodiment, the specific structural design of each component in the display screen, the display screen, the adhesive, and the housing in this embodiment is more clearly elaborated. Specifically, the sealant 4 is disposed in the edge area of the TFT glass 23 that is not covered by the CF glass 22. This area is a sensitive area that requires additional protection.

[0086] It should be noted that in the structure of the display device, during the stacking process of the TFT glass 23 and the CF glass 22, due to design or manufacturing requirements, the CF glass 22 does not completely cover all areas of the TFT glass 23, especially at its edge part. As mentioned above in item 2, since there are ICs in this area that require additional protection to prevent external environmental erosion or interference. Therefore, it is necessary to set the sealant 4 on this set area to form a solid protective barrier.

[0087] Please refer to Figure 3-4 again to more clearly understand the specific position and layout method of the tape 3 in this embodiment. In an implementation manner of this embodiment, in addition to being disposed on the side of the sealant 4 away from the optical component, that is, on the surface of the sealant 4, the tape 3 is also clearly disposed in the edge area of the CF glass 22 that is not covered by the polarizer 21, that is, on the surface of the CF glass 22.

[0088] It should be noted that on the one hand, the application of the tape 3 on the surface of the CF glass 22 and on the surface of the sealant 4 plays a role in further fixing and protecting the sealant 4. Although the sealant 4 itself has certain adhesiveness, in some cases, its adhesiveness may decrease or fail due to external factors (such as temperature changes, humidity fluctuations, etc.). The addition of the tape 3 can form an additional protective barrier to prevent the sealant 4 from falling off or shifting, thereby ensuring its effective sealing and protection of the set area.

[0089] On the other hand, from the perspective of the manufacturing process, setting the tape 3 on the surface of the CF glass 22 and on the surface of the sealant 4 also facilitates the subsequent assembly and debugging work. During the manufacturing process of the display device, the precise alignment and fixation of each component are crucial. The addition of the tape 3 provides more convenience and flexibility for this process, enabling the manufacturer to more easily achieve the precise docking and fixation between components.

[0090] Please refer to again Figure 3-4 , in an implementation manner of this embodiment, the adhesive 6 is also disposed between the polarizer 21 on the side away from the CF glass 22 and the housing 1.

[0091] It should be noted that in addition to being disposed between the housing 1 and the tape 3, the adhesive 6 is also disposed between the polarizer 21 on the side away from the CF glass 22 and the housing 1. This design ensures a tight connection between the display screen and the housing 1, forming a stable mechanical structure. The excellent adhesion performance of the adhesive 6 can resist the stress generated due to external environmental changes (such as temperature fluctuations, humidity changes, etc.), thereby maintaining the stability between the display screen and the housing 1. At the same time, this design also helps to improve the waterproof and dustproof performance of the whole machine, ensuring the normal operation of the display screen in a harsh environment.

[0092] Please refer to again Figure 2-4 , in an implementation manner of this embodiment, the display screen further includes a backlight module 7;

[0093] The backlight module 7 includes an iron frame 71 and a light source component 72;

[0094] The light source component 72 is disposed within the iron frame 71;

[0095] The optical component 2 is disposed within the iron frame 71 and on the side of the light source component 72 away from the iron frame 71.

[0096] It should be noted that the backlight module 7 is an important part of the display screen responsible for providing light source, which directly affects the brightness, uniformity, and color performance of the display screen. Specifically, the backlight module 7 is composed of two main parts: an iron frame 71 and a light source component 72.

[0097] The iron frame 71, as the support structure of the backlight module 7, not only provides a stable installation platform for the light source component 72 but also ensures the positioning accuracy and stability of the entire backlight module 7 in the display screen. The selection of its material and the structural design have been carefully considered to meet the requirements of the display screen for strength, weight, and heat dissipation performance.

[0098] The light source component 72 is disposed inside the iron frame 71 and is the core part of the backlight module 7. It includes a plurality of light-emitting elements (such as LED lamp beads), and these light-emitting elements can emit bright and uniform light after being powered on. These lights are further processed and modulated by the optical component 2, and finally form the display screen we see.

[0099] It should be noted that, in this embodiment, the optical component 2 is disposed on the side of the light source component 72 away from the iron frame 71. This layout design enables the light emitted by the light source component 72 to directly irradiate the optical component 2, and then through the cooperation of elements such as the polarizing plate 21, the CF glass 22, and the TFT glass 23, the display of the image and the presentation of colors are realized.

[0100] Although terms such as housing, optical component, tape, and sealant are used more frequently in this application, the possibility of using other terms is not excluded. These terms are only used to more conveniently describe and explain the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.

[0101] A display device provided by the present utility model can achieve the flattening of the tape by arranging a spacer between the sealant and the tape, and the spacer supports the tape. When the housing is adhesively connected to the tape through the adhesive, the overall flatness of the adhesive surface is improved, thereby increasing the activation area of the adhesive on the housing and avoiding the phenomenon of glue opening. This not only improves the overall aesthetics of the product but also increases the structural integrity and service life of the product.

Specifically, the display device therein effectively solves the problems existing in traditional display devices in terms of the flatness of the adhesive surface, sealing performance, and color presentation due to its ingenious structural design.

[0105] Finally, it should be noted that although the above embodiments have been described in the text of the specification and the drawings of this application, the patent protection scope of this application cannot be limited thereby.
