Description

Technical Field

[0001] This invention relates to a display device. Background Technology

[0002] The main components of a liquid crystal display (LCD) device include a backlight module and a display module. Based on the light incident method, backlight modules can be divided into edge-lit backlight modules and direct-lit backlight modules. Generally speaking, edge-lit backlight modules have the advantages of thinness and low cost; on the other hand, direct-lit backlight modules have better local dimming effects, resulting in better image contrast. The display module is positioned opposite the backlight module to convert the surface light source generated by the backlight module into an image.

[0003] Generally, liquid crystal display (LCD) devices consist of a liquid crystal panel and an optical film. To provide dust protection, existing display components typically also include a seal near the optical film. The optical film is prone to warping when heated, but in current technology, insufficient space is left between the seal and the optical film for deformation. Therefore, after warping, the optical film compresses the seal, causing localized stress concentration and leading to problems such as light leakage. Summary of the Invention

[0004] The present invention provides a display device that provides dust protection and allows sufficient margin for deformation of the display components.

[0005] To achieve one or more of the above-mentioned objectives or other objectives, the display device provided by the present invention includes a middle frame, a display assembly, and a flexible sealing strip. The middle frame has a top, a base, an inner side, and an outer side. The inner side and the outer side are opposite to each other. The top and the base are opposite to each other, and the top is located between the inner side and the outer side. The base is connected to the inner side. The display assembly is disposed on the base. The flexible sealing strip seals between the display assembly and the inner side, and has a first segment and a second segment connected together. The first segment is bent relative to the second segment and has a first end and a fixing area. The first end is opposite to a connecting side of the first segment connecting to the second segment. The fixing area is located between the first end and the connecting side and is fixed to the display assembly. The second segment is fixed to the inner side and has opposite top and bottom ends. The bottom end is close to the base, and the top end is close to the top and connects to the connecting side of the first segment. There is a first height between the top end and the base, and a second height between the fixing area and the base. The first height is greater than or equal to the second height.

[0006] In one embodiment of the invention, the display assembly described above may include multiple optical films. The mid-frame also has an opening and a receiving space. An inner side and a base surround the receiving space. The opening extends through the top and communicates with the receiving space. The optical films are stacked within the receiving space, with the optical film closest to the opening being the top optical film. The first segment may also have a glue-free area, which is located between the fixing area and the connecting side. The top optical film has a surface facing the opening. The fixing area is fixed to the surface, and the glue-free area extends onto the surface.

[0007] In one embodiment of the invention, the display device further includes, for example, an adhesive layer disposed in the fixing region and not extending into the adhesive-free region. The fixing region is connected to the surface via the adhesive layer. The top optical film also has a side surface connecting to the surface, and the side surface faces the second segment. The orthographic projection of the first end onto the surface is a boundary, and the surface has a first width between the boundary and the side surface. The adhesive layer has a first side and a second side. The first side and the second side are opposite to each other, and the second side faces the second segment. There is a second width between the first side and the second side. The second width is, for example, less than or equal to the first width.

[0008] In one embodiment of the invention, the first side described above may not extend to the first end or may be flush with the first end.

[0009] In one embodiment of the present invention, the display device described above may further include a front frame. The front frame is disposed at the top and covers the flexible sealing strip from the top. A first segment is opposite to and spaced apart from the front frame.

[0010] In one embodiment of the present invention, the aforementioned front frame may overlap the first end.

[0011] In one embodiment of the invention, the aforementioned flexible sealing strip further includes, for example, a third segment. The second segment connects the first and third segments, and the third segment extends between the seat and the display assembly. The display assembly is disposed on the third segment and is adapted to move relative to the third segment.

[0012] In one embodiment of the present invention, the third segment described above may be fixed to the base.

[0013] In one embodiment of the present invention, the display device may further include a support member located between the base and the display assembly. A third segment extends between the support member and the display assembly, and the third segment is, for example, fixed to the support member.

[0014] In one embodiment of the invention, the aforementioned inner surface may have a first corner, a first surface, and a second surface, with the first corner connecting the first surface and the second surface. The display assembly, for example, has a second corner corresponding to the first corner. The flexible sealing strip includes a first portion and a second portion. The first portion seals between the display assembly and the first surface, while the second portion seals between the display assembly and the second surface. The first portion and the second portion extend to the first corner and the second corner, and may overlap each other at the first corner and the second corner.

[0015] The display device of the present invention employs a flexible sealing strip to seal the space between the display component and the mid-frame. A first section of the flexible sealing strip is fixed to the display component, and a second section is fixed to the mid-frame. The second height of the second section of the flexible sealing strip from the base is greater than or equal to the first height of the first section from the base, keeping the first section in a relaxed state before it is compressed by the display component. Therefore, when the display component begins to deform and push against the flexible sealing strip, the first section can receive the external force applied by the display component and exhibit a greater deformation amplitude than the display component as the external force increases, thereby absorbing the pushing force from the display component in real time and allowing the display component to deform continuously without restriction. Based on the above, the display device of the present invention not only provides dustproof functionality but also provides sufficient margin for the deformation of the display component, thereby improving optical quality.

[0016] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the present invention more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0025] Figure 1 This is a partial cross-sectional schematic diagram of a display device according to an embodiment of the present invention. Figure 2 yes Figure 1 A magnified view of a portion of the image. Please refer to... Figure 1 and Figure 2 The display device 100 includes a middle frame 110, a display assembly 120, and a flexible sealing strip 130. The middle frame 110 has a top 111, a base 112, an inner side 113, and an outer side 114. The inner side 113 and the outer side 114 are opposite to each other. The top 111 and the base 112 are opposite to each other, and the top 111 is located between the inner side 113 and the outer side 114. The base 112 is connected to the inner side 113. The display assembly 120 is disposed on the base 112. The flexible sealing strip 130 seals between the display assembly 120 and the inner side 113; for example, the flexible sealing strip 130 can cover and seal the gap G (marked as G) between the display assembly 120 and the inner side 113. Figure 1 The flexible sealing strip 130 has a first segment 131 and a second segment 132 connected to each other. The first segment 131 is bent relative to the second segment 132 and has a first end E1 and a fixing area 1310. The first end E1 is opposite to a connecting side 1311 of the first segment 131 connecting to the second segment 132. The fixing area 1310 is located between the first end E1 and the connecting side 1311 and is fixed to the display assembly 120. The second segment 132 is fixed to the inner side 113 and has an opposing top end TE and a bottom end BE. The bottom end BE is close to the seat portion 112, and the top end TE is close to the top 111 and connects to the connecting side 1311 of the first segment 131. The top end TE has a first height H1 with the seat portion 112, and the fixing area 1310 has a second height H2 with the seat portion 112. The first height H1 is greater than or equal to the second height H2, and in this embodiment, the first height H1 is equal to the second height H2.

[0026] The mid-frame 110 accommodates the display component 120. Specifically, the mid-frame 110 also has an opening O and an accommodating space A (labeled as...). Figure 2The inner side 113 and the base 112 surround the receiving space A. An opening O extends through the top 111 and communicates with the receiving space A. The display component 120 may be disposed within the receiving space A. Furthermore, the display device 100 may also include a front frame 160. The front frame 160 is disposed at the top 111, and the display component 120 may be disposed between the base 112 and the front frame 160. For example, the display device 100 may also include a support member 140 located between the base 112 and the display component 120. In this embodiment, the support member 140 may be fixed to the base 112, and the display component 120 may be placed on the support member 140. The support member 140 can elevate the display component 120 from the base 112, bringing the display component 120 closer to the front frame 160. However, in one embodiment, the display device 100 may omit the support member 140, and the display component 120 may be placed on the base 112. Incidentally, the middle frame 110 in this embodiment can also accommodate the light guide plate P and the light-emitting component L (both shown in the figure). Figure 1 The light guide plate P and the light-emitting component L constitute the backlight module BM. The backlight module BM can be disposed on the side of the base 112 opposite to the display component 120. Furthermore, the backlight module BM is, for example, an edge-lit backlight module, but in one embodiment, the backlight module BM can be a direct-lit backlight module, and the present invention does not impose further limitations on this.

[0027] Display component 120 may include a plurality of optical films 121 and display panels 122, and the optical films 121 and display panels 122 are stacked within accommodating space A. The type of optical film 121 may vary depending on the type of display device. For example, in this embodiment, display device 100 may include a liquid crystal display device, display panel 122 may include a liquid crystal panel, and optical film 121 may include two polarizers. Specifically, the liquid crystal panel may be sandwiched between two polarizers. However, in other embodiments, display device 100 is not limited to the aforementioned liquid crystal display device, and optical film 121 and display panel 122 are not limited to the aforementioned polarizers and liquid crystal panels.

[0028] Figure 3 yes Figure 2 A cross-sectional schematic diagram of the display component extruding a flexible sealing strip. Please refer to... Figure 2 and Figure 3In this embodiment, the display component 120 warps due to heat, thereby compressing the flexible sealing strip 130. Therefore, when the flexible sealing strip 130 is compressed by the display component 120, it can deform in real time, absorbing the amount of warping caused by heat in the display component 120. Thus, even when the display component 120 warps, the flexible sealing strip 130 still provides sufficient space, preventing light leakage caused by the display component 120 warping and compressing other components. The material of the flexible sealing strip 130 may include polyethylene terephthalate (PET), but the invention is not limited thereto.

[0029] In this embodiment, the optical film 121 closest to the opening O is the top optical film 1210. The first segment 131 may also have a non-adhesive region 1312, which is located between the fixing region 1310 and the connecting side 1311. The top optical film 1210 has a surface S facing the opening O. The fixing region 1310 is fixed to the surface S, and the non-adhesive region 1312 extends onto the surface S. Specifically, because the fixing region 1310 is fixed to the top optical film 1210, the fixing region 1310 will not be deformed by the pressure of the display component 120 when the display component 120 warps and squeezes the flexible sealing strip 130. Conversely, since the non-adhesive region 1312 cannot be fixed to the surface S, it can be separated from the surface S and thus deformed by the pressure of the display component 120. Furthermore, since the top optical film 1210 is the component closest to the front frame 160 (or opening O) in the display assembly 120, the surface S of the top optical film 1210 can provide a larger area for fixing the first segment 131. For example, the fixing area 1310 can be fixed in any area where the surface S overlaps with the front frame 160, allowing the fixing area 1310 to be fixed at a position on the surface S further away from the connecting side 1311. This also increases the length of the adhesive-free area 1312, allowing the first segment 131 to absorb more of the warpage generated by the display assembly 120, thereby further improving the deformation margin of the display assembly 120. Incidentally, the top optical film 1210 may include, for example, the aforementioned polarizer, but the present invention does not impose further limitations on this.

[0030] The display device 100 in this embodiment also includes, for example, an adhesive layer 150 (also shown in...). Figure 1An adhesive layer 150 is disposed in the fixing area 1310 and does not extend into the adhesive-free area 1312. The fixing area 1310 is connected to the surface S via the adhesive layer 150. The top optical film 1210 also has a side SS connecting to the surface S, and the side SS faces the second segment 132. The orthographic projection of the first end E1 onto the surface S is a boundary B, and the surface S has a first width W1 between the boundary B and the side SS. The adhesive layer 150 has a first side 151 and a second side 152. The first side 151 and the second side 152 are opposite each other, and the second side 152 faces the second segment 132. There is a second width W2 between the first side 151 and the second side 152. The second width W2 is, for example, less than or equal to the first width W1, and in this embodiment, the second width W2 is less than the first width W1. In other words, the fixing area 1310 of the first segment 131 can be fixed to the surface S via the adhesive layer 150, while the adhesive-free area 1312 of the first segment 131 is separated from the surface S. This also increases the deformability of the first segment 131, thus providing more margin for the deformation of the display component 120. In this embodiment, the first side 151 can be flush with the first end E1, allowing the first segment 131 to cover the adhesive layer 150. In another embodiment, for example... Figure 4 The display device 100a shown has a first side 151a that, for example, does not extend to the first end E1, allowing the first segment 131 to better cover the adhesive layer 150a. Please refer to [further details]. Figure 2 In this embodiment, the second segment 132 can be fixed to the inner surface 113 via another adhesive layer AL. Furthermore, the adhesive layer can extend from the top end TE to the bottom end BE, but the present invention does not impose further limitations on this.

[0031] Please refer to this again. Figure 1 and Figure 2 In this embodiment, the front frame 160 can cover the flexible sealing strip 130 at its top 111. The first segment 131 is opposite to and spaced apart from the front frame 160 to provide space for deformation of the first segment 131. Additionally, the front frame 160 can prevent the flexible sealing strip 130 from being exposed from the opening O. For example, the front frame 160 can overlap the first end E1 to cover the flexible sealing strip 130. Specifically, the front frame 160 can overlap the first end E1 in the normal direction of surface S, but the present invention does not impose further limitations on this.

[0032] Figure 5 yes Figure 1 A partial top view of the display device. It should be noted that... Figure 5 Omit Figure 1 The front bezel 160 is used to clearly present the structure of the display device 100. Please refer to... Figure 5In this embodiment, the inner surface 113 may have a first corner C1, a first surface SS1, and a second surface SS2, with the first corner C1 connecting the first surface SS1 and the second surface SS2. The display assembly 120, for example, has a second corner C2 corresponding to the first corner C1. The flexible sealing strip 130 includes a first portion P1 and a second portion P2. The first portion P1 seals between the display assembly 120 and the first surface SS1, and the second portion P2 seals between the display assembly 120 and the second surface SS2. The first portion P1 and the second portion P2 extend to the first corner C1 and the second corner C2, and may overlap each other at the first corner C1 and the second corner C2 to further improve the sealing between the middle frame 110 and the display assembly 120. For example, the inner surface 113 may have four first corners C1, and the display assembly 120 may have four second corners C2, wherein the first portion P1 and the second portion P2 may overlap each other at each first corner C1 and each second corner C2.

[0033] Compared to existing technologies, the display device 100 in this embodiment uses a flexible sealing strip 130 to seal the space between the display component 120 and the middle frame 110. The first segment 131 of the flexible sealing strip 130 is fixed to the display component 120, and the second segment 132 is fixed to the middle frame 110. The second height H2 of the second segment 132 from the base 112 is greater than or equal to the first height H1 of the first segment 131 from the base 112, thus keeping the first segment 131 in a relaxed state before it is compressed by the display component 120 (see [link]). Figure 2 and Figure 3 Therefore, when the display component 120 begins to deform and push against the flexible sealing strip 130, the first segment 131 can receive the external force applied by the display component 120, and as the external force increases, it exhibits a larger deformation amplitude than the display component 120, so as to absorb the force pushed by the display component 120 in real time, allowing the display component 120 to deform continuously without restriction. Based on the above, the display device 100 of this embodiment not only provides a dustproof function, but also provides sufficient margin for the deformation of the display component 120, thereby improving the optical quality.

[0034] Figure 6 This is a partial cross-sectional schematic diagram of a display device according to another embodiment of the present invention. The structure and advantages of the display device 100b in this embodiment are similar to those of the present invention. Figure 1 The following describes only the differences in the embodiments. Please refer to... Figure 6 The first height H1b between the top TE and the base 112 can be greater than the second height H2 between the fixed area 1310 and the base 112. In this way, the length of the first segment 131b can be further increased, so that the first segment 131b of the flexible sealing strip 130b can have a greater amount of deformability, thereby providing more margin for the deformation of the display assembly 120.

[0035] Figure 7 This is a partial cross-sectional schematic diagram of a display device according to another embodiment of the present invention. Figure 8 This is a partial cross-sectional schematic diagram of a display device according to another embodiment of the present invention. The structure and advantages of the display device 100c in this embodiment are similar to those of the present invention. Figure 1 The following describes only the differences in the embodiments. Please refer to [the previous text]. Figure 7 The flexible sealing strip 130c also includes, for example, a third segment 133. The second segment 132 connects the first segment 131 and the third segment 133, and the third segment 133 extends between the base 112 and the display assembly 120. The display assembly 120 is disposed on the third segment 133 and is adapted to move relative to the third segment 133. Specifically, the third segment 133 further enhances the sealing effect between the display assembly 120 and the middle frame 110. Additionally, the display assembly 120 can be placed on the third segment 133 but not fixed to it, to prevent light leakage caused by the restriction of the third segment 133 when the display assembly 120 warps due to heat. In this embodiment, the third segment 133 may extend between the support member 140 and the display assembly 120, and the third segment 133 may be fixed to the support member 140, for example, but the invention is not limited thereto. For example, please refer to... Figure 8 The display device 100d can be omitted. Figure 7 The support member 140 and the third segment 133 of the flexible sealing strip 130d can be fixed to the seat 112 of the middle frame 110. Similarly, the display assembly 120 can be placed on the third segment 133 but is not fixed to the third segment 133.

[0036] In summary, the display device of the present invention employs a flexible sealing strip to seal the space between the display component and the mid-frame. The first segment of the flexible sealing strip is fixed to the display component, while the second segment is fixed to the mid-frame. Furthermore, the second height of the second segment from the base is greater than or equal to the first height of the first segment from the base, ensuring that the first segment remains relaxed before being compressed by the display component. Therefore, when the display component begins to deform and push against the flexible sealing strip, the first segment can receive the external force applied by the display component and exhibit a greater deformation amplitude than the display component as the external force increases, thus absorbing the pushing force from the display component in real time and providing deformation margin when the display component warps. Based on the above, the display device of the present invention not only provides dustproof functionality but also allows sufficient margin for the deformation of the display component, thereby improving optical quality.

Any person skilled in the art can make some modifications or alterations to the methods and techniques disclosed above without departing from the scope of the present invention to create equivalent embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
