Description

Technical Field

[0001] This application relates to the field of display devices, and more particularly to a display apparatus. Background Technology

[0002] In display devices using related technologies, the polarizer is a core optical component that ensures image quality. However, in actual production and application, light leakage at the edges of the polarizer frequently occurs. Specifically, this manifests as bright lines, halos, or localized whitening at the edges of the polarizer when the display device is working, affecting the display effect. Utility Model Content

[0003] The purpose of this application is to provide a display device that improves the edge light leakage problem of the polarizer and enhances the display effect of the display device.

[0004] To achieve the above objectives, the embodiments of this disclosure provide the following technical solutions: A display device is provided. The display device includes a display module and a decorative strip. The display module includes a display panel, which includes a polarizer, a polarizer substrate, and a thin-film transistor substrate.

All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0023] Unless the context otherwise requires, throughout the specification and claims, the term "comprising" is interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiment," "example," or "some examples" are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, specific features, structures, materials, or characteristics may be included in any suitable manner in any one or more embodiments or examples.

[0024] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0025] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0026] The use of “applies to” or “configured to” in this article implies an open and inclusive language that does not preclude applicability to or configuration to devices that perform additional tasks or steps.

[0027] In addition, the use of "based on" implies openness and inclusivity, because processes, steps, calculations or other actions "based on" one or more conditions or values ​​can in practice be based on additional conditions or values ​​beyond those conditions.

[0028] As used herein, “parallel,” “perpendicular,” and “equal” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the errors associated with the measurement of a particular quantity, i.e., the limitations of the measurement system. For example, “parallel” includes absolute parallelism and approximate parallelism, where the acceptable range of deviation for approximate parallelism can be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where the acceptable range of deviation for approximate perpendicularity can also be, for example, within 5°; “equal” includes absolute equality and approximate equality, where the acceptable range of deviation for approximate equality can be, for example, the difference between the two equals being less than or equal to 5% of either one.

[0029] It should be understood that when a layer or element is referred to as being on another layer or substrate, it can mean that the layer or element is directly on another layer or substrate, or that there is an intermediate layer between the layer or element and another layer or substrate.

[0030] This document describes exemplary embodiments with reference to cross-sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and the area of ​​regions are enlarged for clarity. Therefore, variations in shape relative to the drawings are contemplated due to, for example, manufacturing techniques and / or tolerances. Thus, exemplary embodiments should not be construed as being limited to the shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing processes. For example, etched areas shown as rectangular would typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the areas of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0031] Hereinafter, a display device 100 according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0032] See Figure 1 and Figure 2The display device 100 includes a display module 1 and a decorative strip 2. The display module 1 includes a display panel 12. A polarizer 121 is provided on the display side of the display panel 12. The decorative strip 2 is provided on the display module 1 and serves as the lower frame of the display module 1. The decorative strip 2 includes a first blocking portion 21 located on the light-emitting side of the display panel 12. The first blocking portion 21 includes an extension portion 211 extending to the light-emitting side of the polarizer 121. The extension portion 211 blocks the edge portion of the polarizer 121 from the light-emitting side of the polarizer 121.

[0033] See Figure 1 and Figure 2 The decorative strip 2 serves as the lower side frame of the display module 1. The display panel 12 includes a polarizer 121, a polarizer substrate 122, and a thin-film transistor substrate 123. The polarizer 121 is located on the display side of the display panel 12. The polarizer substrate 122 is supported on the light-incident side of the polarizer 121. The thin-film transistor substrate 123 is disposed on the side of the polarizer substrate 122 away from the polarizer 121. The lower part of the polarizer substrate 122 and the lower part of the thin-film transistor substrate 123 are connected by a connecting part 125. The lower part of the polarizer 121 is provided with a clearance area 121a for avoiding the connecting part 125. The polarizer substrate 122 is not covered by the polarizer 121 at the corresponding clearance area 121a. The first blocking part 21 includes an extension 211 extending upward to the light-emitting side of the polarizer 121. The upper edge of the extension 211 is higher than the clearance area 121a.

[0034] The type of display device 100 is not limited; it can be an LCD (Liquid Crystal Display) or an OLED (Organic Light-Emitting Diode). The form of the polarizer 121 is not limited; it can be a common polarizer or a polarizer with special functions. For example, the polarizer 121 can be a color filter polarizer, and the polarizer substrate 122 can be a color filter light-transmitting substrate, such as a glass substrate. The polarizer substrate 122 provides stable support for the polarizer 121, ensuring that the polarizer 121 does not deform due to external forces or internal stress during the operation of the display panel 12, thereby maintaining the stability of the optical performance of the polarizer 121.

[0035] The decorative strip 2 serves as the bottom border of the display module 1, meaning that the decorative strip 2 is located at the bottom of the display module 1 and extends in the left-right direction. The display module 1 can be a full-border form with borders on all four sides, or it can be a form with only a bottom border and no borders on the other three sides.

[0036] The lower portion of the polarizer substrate 122 and the lower portion of the thin-film transistor substrate 123 are connected by a connecting portion 125. For example, see [link to example]. Figure 3 and Figure 4 The connecting part 125 is a silver paste dot used to realize the grounding connection between the polarizer substrate 122 and the thin film transistor substrate 123. The lower part of the polarizer substrate 122 and the lower part of the thin film transistor substrate 123 are connected by the silver paste dot to realize the electrical conduction between the polarizer substrate 122 and the thin film transistor substrate 123, thereby grounding the polarizer substrate 122 and the thin film transistor substrate 123, and allowing the polarizer substrate 122 and the thin film transistor substrate 123 to perform electrostatic discharge.

[0037] In the above technical solution, by providing a clearance area 121a at the lower part of the polarizer 121 to avoid the portion of the connecting part 125, the portion of the connecting part 125 located on the polarizer substrate 122 can be avoided, thereby preventing the polarizer 121 from being lifted and damaged or protruding by the connecting part 125. Moreover, by setting the upper edge of the extension 211 to be higher than the clearance area 121a, the extension 211 can block the lower edge of the polarizer 121, the lower edge of the polarizer substrate 122, and the clearance area 121a from the light-emitting side of the polarizer 121.

[0038] The term "display side of display panel 12" refers to the side of display panel 12 facing the user, such as the front side of display panel 12. The term "light-emitting side of polarizer 121" refers to the side of polarizer 121 facing the user, such as the front side of polarizer 121.

[0039] The decorative strip 2 serves to decorate, shield, and to some extent protect the edges of the display module 1. In daily use, the frame of the display module 1 may be subjected to external forces such as collisions and friction, making it a relatively vulnerable part. The decorative strip 2 acts as a buffer and protector. The extension 211 of the decorative strip 2 shields the edge of the polarizer 121 from the light-emitting side, reducing the direct impact of external forces on the edge of the polarizer 121, extending its lifespan, and contributing to the long-term stable operation of the display device 100.

[0040] During the operation of the display device, the edges of the polarizer are prone to light leakage, resulting in bright lines or color abnormalities in the edge area of ​​the display module. In the technical solution of this application, since the decorative strip 2 includes a first blocking part 21 located on the light-emitting side of the display panel 12, the extension part 211 of the first blocking part 21 blocks the edge of the polarizer 121 from the light-emitting side of the polarizer 121. The extension part 211 can block light leakage at the edge of the polarizer 121. The light path of the leaked light is blocked by the extension part 211, so that the user cannot see the light leakage at the edge of the polarizer 121, thus improving the problem of light leakage at the edge of the polarizer 121.

[0041] Furthermore, the extension 211, by shielding the edge of the polarizer 121, can reduce light scattering and reflection at the edge of the polarizer 121, thereby reducing light interference and further improving image contrast and color reproduction. Additionally, if the decorative strip and the display panel are edge-to-edge spliced ​​without overlapping shielding, the splicing gap will be visible from a front view due to tolerance limitations. In the technical solution of this application, since the decorative strip 2 includes a first shielding portion 21 located on the light-emitting side of the display panel 12, the extension 211 of the first shielding portion 21 shields the edge of the polarizer 121 from the light-emitting side, thus preventing the formation of a splicing gap between the display panel 12 and the decorative strip 2.

[0042] See Figure 1 and Figure 2 In some embodiments, on a projection surface parallel to the polarizer 121, the orthographic projection of the extension 211 and the orthographic projection of the polarizer 121 form an overlapping region R, which is elongated and extends from the left end to the right end of the lower edge of the polarizer 121.

[0043] The overlapping area R refers to the portion on the projection surface where the orthographic projection of the extension 211 and the orthographic projection of the polarizer 121 overlap, reflecting the range of occlusion of the edge of the polarizer 121 by the extension 211. The overlapping area R is elongated and extends from one end of the length of the corresponding side edge of the polarizer 121 to the other end. Here, the corresponding side edge refers to the side edge of the polarizer 121 that is occluded by the extension 211 (such as the lower edge shown in the figure). The shape of the extension 211 is adapted to the elongated edge of the polarizer 121, and it can completely block along the edge of the polarizer 121.

[0044] For example, the width A of the overlapping region R in the vertical direction includes, but is not limited to, 0.3mm-5.5mm, and the width A of the overlapping region R in the direction perpendicular to the corresponding side edge of the polarizer 121 can be 0.3mm, 0.5mm, 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, 4.0mm, 4.5mm, 5.0mm, 5.5mm, etc.

[0045] In the above technical solution, the overlapping area R is elongated and extends from one end of the length of the corresponding side edge of the polarizer 121 to the other end, so that the extension 211 can completely cover the entire edge length of the polarizer 121, thereby making the occlusion more comprehensive. Users will find it difficult to see light leakage at the edge of the polarizer 121 from different angles, reducing bright lines and color differences at the edge of the screen, making the display screen more uniform and clear, and thus improving the overall display quality.

[0046] In the above technical solution, the width A of the overlapping region R in the direction perpendicular to the corresponding side edge of the polarizer 121 includes, but is not limited to, 0.3mm-5.5mm. If the width is too small, it may not be able to completely block the abnormal light from the edge of the polarizer 121, resulting in light leakage that users can still see from the edge of the polarizer 121 at certain viewing angles; if the width is too large, it may block too much of the normally displayed image, resulting in wasted display space, increasing the width of the bottom bezel of the display module 1, thereby reducing the aesthetics of the product and increasing the production cost of the display device 100 with the same image size. Therefore, the width of the overlapping region R is 0.3mm-5.5mm, which can minimize the impact on the normal display image size while blocking the abnormal light from the edge of the polarizer 121, thereby improving display quality and saving production costs.

[0047] In some embodiments, the decorative strip 2 and the display module 1 are connected by at least one of the following methods: fastener connection, snap-fit, and adhesive bonding. For example, the decorative strip 2 and the display module 1 can be connected by one or more of the following methods: screw fastening, mechanical hook engagement, and adhesive bonding. Fastener connections provide a strong and reliable connection, ensuring the stability and reliability of the display device 100 during long-term use, reducing malfunctions and maintenance costs caused by loose connections, thereby improving the quality of the display device 100. Snap-fit ​​and adhesive bonding methods are convenient and quick, reducing assembly time and labor costs during production, and improving production efficiency. Therefore, a suitable connection method can be flexibly selected based on factors such as the different materials of the display device 100 and the decorative strip 2, different connection positions, usage scenarios, and costs. Of course, the above connection methods can also be combined to achieve a better connection effect.

[0048] See Figure 2 In some embodiments, the first shielding portion 21 is bonded to the display panel 12. Exemplarily, the first shielding portion 21 and the display panel 12 can be bonded together using adhesive, tape, double-sided tape 13, etc. The display panel 12 is relatively fragile and prone to problems such as pressure spots when subjected to uneven force. Adhesive bonding is a simpler process, provides uniform bonding force, and is less likely to cause pressure on the display panel 12, reducing damage during the connection process. Furthermore, compared to some mechanical connection methods (such as screw fixing), adhesive bonding does not require machining holes or threads on the first shielding portion 21 and the display panel 12, reducing processing steps and costs, and improving production efficiency.

[0049] See Figure 2 or Figure 11In some embodiments, the extension 211 of the decorative strip 2 is bonded to the polarizer 121. Since the polarizer 121 is located on the light-emitting side of the display panel 12 and is close to the decorative strip 2, the decorative strip 2 is easy to bond and fix to the polarizer 121 of the display panel 12, and the bonding process is relatively simple, making it easier to achieve mass production. In addition, the bonding of the extension 211 of the decorative strip 2 to the polarizer 121 reduces the gap between the two, which can prevent dust, moisture and other impurities from entering the interior of the display panel 12 to a certain extent, protecting the internal components of the display panel 12 (such as transistors on the thin-film transistor substrate 123).

[0050] See Figure 2 and Figure 3 In some embodiments, the lower edge of the polarizer 121 is flush with the lower edge of the polarizer substrate 122, and the clearance area 121a is configured as a notch formed in the lower part of the polarizer 121 and is provided corresponding to the connecting portion 125.

[0051] In the above technical solution, a notch-shaped clearance area 121a is formed at the lower part of the polarizer 121 at the corresponding connecting part 125. This clearance area can be used to avoid the portion of the connecting part 125 located on the polarizer substrate 122, thereby allowing the decorative strip 2 to better fit with the lower edge of the polarizer 121. The lower edge of the polarizer 121 is flush with the lower edge of the polarizer substrate 122, which can increase the area of ​​the polarizer 121. The lower edge of the polarizer 121 can be used to bond with the extension 211, thereby reducing the obstruction of the screen size that can be displayed normally and improving the display effect.

[0052] For example, see Figure 3 and Figure 4 There are two connecting portions 125, which are distributed at the left and right ends of the lower part of the polarizer substrate 122. There are also two clearance areas 121a, which are respectively provided corresponding to the two connecting portions 125. That is, connecting portions 125 can be provided at the left and right ends of the lower part of the polarizer substrate 122, and clearance areas 121a can be provided corresponding to the two connecting portions 125, thereby improving the connection reliability between the polarizer substrate 122 and the thin film transistor substrate 123, and maximizing the bonding area between the lower edge of the polarizer 121 and the decorative strip 2.

[0053] The shape of the avoidance area 121a is not limited; for example, it can include, but is not limited to, an upper semicircle (i.e., the upper half of a circle), a rectangle, a chamfered shape, or an irregular shape, thereby allowing for flexible configuration of the avoidance area 121a. (Refer to...) Figure 5 The semi-circular clearance area 121a makes the clearance area 121a smoother, and the arc shape can better bear and disperse force, making the connection part 125 less prone to bumps and damage; see reference Figure 3The rectangular clearance area 121a can provide a positioning reference for the connection part 125. (Refer to...) Figure 6 The chamfered clearance area 121a can be understood as a beveled angle set at the edge. For example, the clearance area 121a can be an unequal-sided chamfer, that is, the chamfer length of the lower edge of the polarizer 121 is not equal to the chamfer length of the side edge of the polarizer 121, so as to better adapt to the setting position of the connecting part 125 and better bear and disperse the force, making the connecting part 125 less prone to bumping and damage. Of course, the clearance area 121a can also be an equilateral chamfer, which will not be elaborated here.

[0054] For example, the connecting part 125 is a silver paste dot, which makes it easier to align the position when applying the silver paste dot, thus ensuring the function of the connecting part 125. Of course, an irregular shape design can also be made according to the shape of the connecting part 125, so that the irregular avoidance area 121a can fit the shape of the connecting part 125 more closely.

[0055] The shape of the avoidance area 121a can be obtained by means including but not limited to stamping, die cutting, wire cutting, laser engraving, etc.

[0056] Reference Figure 7 or Figure 12 In some embodiments, there is a gap between the extension 211 and the polarizer 121 along the thickness direction of the display panel 12, and the first shielding part 21 is directly bonded to a portion of the surface of the polarizer substrate 122, that is, the first shielding part 21 is bonded to the lower part of the polarizer substrate 122 that is not covered by the polarizer 121.

[0057] In the above technical solution, by directly bonding the first shielding part 21 to a portion of the surface of the polarizer substrate 122, a gap exists between the extension 211 of the decorative strip 2 and the polarizer 121. This reduces the pressure exerted by the decorative strip 2 on the polarizer 121, thus reducing the problem of stress light leakage in the display module 1 caused by stress light leakage. This ensures the stable optical performance of the polarizer 121. Furthermore, the gap fit reduces the problem of scratching the polarizer 121 due to improper assembly of the extension 211 of the decorative strip 2.

[0058] In some embodiments, the lower edge of the polarizer 121 is a horizontal line and is higher than the connecting portion 125. The clearance area 121a is formed below the lower edge of the polarizer 121. The portion of the lower part of the polarizer substrate 122 located below the lower edge of the polarizer 121 is the mounting portion 1221. The first shielding portion 21 is bonded to the mounting portion 1221.

[0059] In the above technical solution, the lower edge of the polarizer 121 is a horizontal line and is higher than the connecting part 125. The area below the lower edge of the polarizer 121 is all the avoidance area 121a. The part of the lower part of the polarizer substrate 122 located below the lower edge of the polarizer 121 can all be used to bond the first shielding part 21, thereby reducing the processing difficulty of the polarizer 121 while satisfying the avoidance of the connecting part 125.

[0060] Reference Figure 9 In some embodiments, the bonding height B between the first shielding portion 21 and the mounting portion 1221 in the vertical direction is 2mm-6mm. For example, the bonding height B between the first shielding portion 21 and the mounting portion 1221 of the polarizer substrate 122 can be 2mm, 3mm, 4mm, 5mm, 6mm, etc. This ensures sufficient bonding area and bonding strength between the first shielding portion 21 and the polarizer substrate 122 while maintaining a relatively economical cost. If the bonding height is too small, for example, less than 2mm, sufficient adhesive force cannot be provided, making it easy for the decorative strip 2 to detach from the mounting portion 1221 of the polarizer substrate 122 during use. Conversely, if the bonding height is too large, it increases material costs and occupies too much space, encroaching on the screen size that can be displayed normally, thus increasing the production cost of display devices 100 with the same screen size.

[0061] Reference Figure 9 In some embodiments, the first shielding part 21 and the mounting part 1221 are bonded together by double-sided adhesive 13. The thickness of the double-sided adhesive 13 is greater than the thickness of the polarizer 121. The gap C between the extension part 211 and the polarizer 121 along the thickness direction of the display panel 12 is 0.03mm-0.3mm.

[0062] For example, the double-sided tape 13 can be ordinary double-sided tape, or black easy-pull tape, etc.

[0063] For example, the gap C between the extension 211 of the decorative strip 2 and the polarizer 121 can be 0.03mm, 0.05mm, 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, etc.

[0064] In the above technical solution, double-sided adhesive 13 is used to bond the first shielding part 21 and the mounting part 1221 of the polarizer substrate 122. Compared with some other bonding methods, such as dispensing, which may have uneven glue distribution, double-sided adhesive 13 can cover the bonding surface more evenly, reducing the risk of the first shielding part 21 falling off due to poor bonding, thereby improving the reliability of the display device 100.

[0065] In the above technical solution, the thickness of the double-sided adhesive 13 is greater than the thickness of the polarizer 121. Therefore, the gap C between the extension 211 of the decorative strip 2 and the polarizer 121 can be controlled by adjusting the thickness of the double-sided adhesive 13. The gap C is set to 0.03mm-0.3mm. This ensures sufficient gap C between the decorative strip 2 and the polarizer 121, reducing the risk of scratching the polarizer 121 due to improper assembly of the extension 211 during the bonding process between the decorative strip 2 and the display panel 12, thus improving assembly reliability. Furthermore, the gap also ensures the stability of the optical performance of the polarizer 121.

[0066] See Figure 1 and Figure 2 In some embodiments, the display module 1 includes a back module 11, which is disposed on the non-display side of the display panel 12. The back module 11 includes a boss portion 111, which protrudes toward the display side of the display panel 12 and extends to the bottom of the display panel 12. The first blocking portion 21 is bonded to the boss portion 111.

[0067] The back module 11 is not limited. For example, when the display device 100 is an LCD, the back module 11 can be a backlight, and when the display device 100 is an OLED, the back module 11 can be a back panel.

[0068] In the above technical solution, the boss portion 111 protrudes towards the display side of the display panel 12 and extends below the display panel 12, providing an additional bonding position for the first shielding portion 21, increasing the connection area between the decorative strip 2 and the first shielding portion 21 and the back module 11. The first shielding portion 21 is bonded to the boss portion 111 and the display panel 12, so that the decorative strip 2 can be better attached and fixed to the display module 1, thereby improving the display reliability and stability of the display device 100.

[0069] See Figure 2 In some embodiments, the first shielding portion 21 is a planar structure of the parallel polarizer 121. In the thickness direction of the polarizer 121, the distance X1 between the boss portion 111 and the first shielding portion 21 is smaller than the distance X2 between the thin film transistor substrate 123 and the first shielding portion 21. That is, in the thickness direction of the polarizer 121, the boss portion 111 is closer to the first shielding portion 21.

[0070] In the above technical solution, the polarizer substrate 122 provides stable support for the polarizer 121, ensuring that the polarizer 121 will not be deformed due to external force or internal stress during the operation of the display panel 12, thereby maintaining the stability of the optical performance of the polarizer 121.

[0071] In the above technical solution, the distance between the boss portion 111 and the first shielding portion 21 is smaller than the distance between the thin film transistor substrate 123 and the first shielding portion 21. This facilitates the bonding and fixing of the boss portion 111 and the first shielding portion 21, improving the strength of the connection. Moreover, the first shielding portion 21 does not need to protrude or excessively protrude towards the boss portion 111 in order to bond with it. This allows the first shielding portion 21 to be in a planar or near-planar form, simplifying the processing of the first shielding portion 21.

[0072] Reference Figure 9 In some embodiments, the first blocking portion 21 is a sheet-like structure with its wall thickness direction aligned with the thickness direction of the display panel 12. Regardless of the material of the decorative strip 2, the thickness H1 of the first blocking portion 21 is 0.15mm-0.4mm. For example, the thickness H1 of the first blocking portion 21 is 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, etc. Therefore, the decorative strip 2 protrudes only slightly from the polarizer 121 in the thickness direction, allowing it to visually blend with the display panel 12, achieving a near-borderless display effect.

[0073] Reference Figure 7 In some embodiments, when the display module 1 includes a back module 11, the decorative strip 2 is an integrally formed metal part and also includes a second shielding part 22. The second shielding part 22 is connected to the lower end of the first shielding part 21 and extends to the bottom of the display module 1. The second shielding part 22 is a sheet with the wall thickness direction in the up-down direction and is attached to the bottom of the back module 11.

[0074] In the above technical solution, the decorative strip 2 also includes a second shielding part 22. When the display device 100 is bumped, the second shielding part 22 can protect the bottom of the display module 1, thereby improving the structural stability and reliability of the entire display device 100. The second shielding part 22 is attached (adhered or directly in contact) to the bottom of the back module 11, which can reduce the protrusion of the second shielding part 22.

[0075] In the above technical solution, the decorative strip 2 is a one-piece molded metal part, which is beneficial to the overall structural strength of the decorative strip 2. Compared with plastic decorative strips, metal decorative strip 2 is easier to make thinner, thus enabling the decorative strip 2 to visually blend with the display panel 12. In addition, metal decorative strip 2 is not easily affected by environmental factors and is not prone to deformation or aging. It also has a high thermal conductivity, which is beneficial to the heat dissipation of the display device 100.

[0076] For example, the thickness H2 of the second blocking portion 22 along the vertical direction is 0.15mm-0.4mm. For example, the thickness H2 of the second blocking portion 22 is 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, etc. As a result, the decorative strip 2 is relatively thin, and it can be visually integrated with the display panel 12.

[0077] For example, when the decorative strip 2 is a one-piece metal part and also includes a second blocking portion 22, the decorative strip 2 can be a steel plate with equal wall thickness. For example, the thickness of the first blocking portion 21 and the second blocking portion 22 is equal, thereby making the thickness of the decorative strip 2 more uniform. Of course, the decorative strip 2 can also be in the form of unequal wall thickness, for example, the thickness of the first blocking portion 21 and the second blocking portion 22 is not equal.

[0078] In some embodiments, the decorative strip 2 is made of stainless steel sheet, electrolytic galvanized steel sheet (also known as SECC), hot-dip galvanized aluminum-magnesium steel sheet (also known as SGLC), or hot-dip galvanized steel sheet (also known as SGCC). Therefore, the decorative strip 2 has good structural strength and is relatively thin.

[0079] For example, decorative strip 2 is made of stainless steel sheet with uniform wall thickness and sprayed black, and is installed using black easy-pull adhesive. Therefore, decorative strip 2 is easy to install, relatively thin, and the extension 211 covers the edge of polarizer 121, blocking the light leakage path. This prevents users from seeing light leakage at the edge of polarizer 121, and decorative strip 2 can reduce light scattering and reflection at the edge, reducing light interference and further improving the contrast and color reproduction of the displayed image.

[0080] Reference Figure 10 , Figure 11 and Figure 12 In some embodiments, the display module 1 includes a back module 11, which is located on the non-display side of the display panel 12. The decorative strip 2 includes an outer part 2a and an inner part 2b. The outer part 2a is a one-piece molded plastic part and includes a first blocking part 21 and a third blocking part 23. The third blocking part 23 is connected to the lower end of the first blocking part 21 and extends to the bottom of the display module 1. The inner part 2b is a metal part and is disposed between the third blocking part 23 and the bottom of the back module 11. Both the third blocking part 23 and the inner part 2b are sheet-like with their wall thickness direction in the vertical direction. That is, the inner part 2b is disposed on the side of the third blocking part 23 facing the bottom of the back module 11, and the inner part 2b is sheet-like with its wall thickness direction consistent with the wall thickness direction of the third blocking part 23, both of which have their wall thickness directions in the vertical direction.

[0081] For example, the appearance part 2a is a PC (abbreviation for Polycarbonate) or PET (abbreviation for Polyethylene Terephthalate) sheet that is integrally formed by hot bending, with a thickness of 0.1mm-1.2mm. For example, the thickness of the appearance part 2a is 0.1mm, 0.125mm, 0.25mm, 0.38mm, 0.5mm, 0.8mm, 1.2mm, etc. The appearance part 2a includes a first blocking part 21 and a third blocking part 23. The first blocking part 21 and the third blocking part 23 are formed by hot bending through a mold to form an included angle α, which is 80°-90°. For example, the included angle α of the first blocking part 21 and the third blocking part 23 can be 80°, 82°, 84°, 86°, 88°, 90°, etc.

[0082] In the above technical solution, the decorative strip 2 adopts a structure combining the outer part 2a and the inner part 2b. The outer part 2a is a one-piece molded plastic part, which can reduce manufacturing costs and weight. Moreover, the one-piece molding process makes the outer part without connecting seams, thus presenting a better appearance. At the same time, the first shielding part 21 and the third shielding part 23 can shield the display module 1, reducing the exposure of the internal structure of the display module 1 and affecting the overall visual effect.

[0083] For example, the inner liner 2b is made of SUS stainless steel, or electrolytic galvanized steel sheet (also known as SECC), or hot-dip galvanized aluminum-magnesium steel sheet (also known as SGLC), or hot-dip galvanized steel sheet (also known as SGCC), or titanium alloy, etc., with a thickness of 0.15mm-1.2mm. For example, the thickness of the inner liner 2b is 0.15mm, 0.25mm, 0.38mm, 0.5mm, 0.8mm, 1.2mm, etc.

[0084] In the above technical solution, the inner lining 2b is a metal part. The metal part has high strength and rigidity. It is set between the third shielding part 23 and the bottom of the back module 11, which can provide more stable support and fixation for the entire decorative strip 2, enhance the stability of the combination of the display module 1 and the decorative strip 2, and reduce problems such as structural loosening and deformation of the decorative strip 2 caused by external impact or long-term use.

[0085] For example, the outer part 2a and the inner liner 2b are connected by an adhesive 24, which can be glue or double-sided tape, etc. The assembly order of the outer part 2a, the inner liner 2b, and the display panel 12 is not limited. For example, during production and installation, the outer part 2a and the inner liner 2b can be connected first to form a decorative strip 2 using the adhesive 24, and then the decorative strip 2 can be connected to the display panel 12. Alternatively, the inner liner 2b can be positioned and fixed to the bottom of the back module 11 first, and then the outer part 2a and the inner liner 2b can be connected using the adhesive 24.

[0086] In some embodiments, reference Figure 11 and Figure 12 The polarizer 121 is a color filter polarizer, also known as an upper polarizer. The polarizer substrate 122 is a color filter substrate. A lower polarizer 124 is provided on the side of the thin-film transistor substrate 123 opposite to the polarizer substrate 122. Thus, by using a color filter polarizer as the upper polarizer and a color filter substrate as the polarizer substrate 122, the color filter polarizer can precisely control the transmission of different colors of light. The lower polarizer 124 is provided on the side of the thin-film transistor substrate 123 opposite to the polarizer substrate 122. The color filter polarizer (upper polarizer) and the lower polarizer 124 work together to effectively control the propagation direction and polarization direction of light, reduce light leakage, improve light utilization, and thereby enhance the contrast and brightness of the display device 100, making the picture clearer and brighter. Of course, this application is not limited to this; the polarizer 121 can be set to other types depending on the specific type of the display panel 12. For example, in some other embodiments, the polarizer 121 can also be a thin-film transistor polarizer.

[0087] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
