Technical Field

[0001] This application relates to the field of display technology, specifically to a display module. Background Technology

[0002] Due to the technical challenge of requiring a bonding area on the ground side of the display panel, existing narrow-bezel or bezel-less LCD modules are primarily 3BL (3-Border Less) structures. Conventional 3BL LCD modules feature a decorative strip on the bottom bezel. Because this decorative strip differs significantly from the top, left, and right bezels, a visual color difference occurs in the bottom bezel area. Utility Model Content

[0003] Embodiments of this application provide a display module to improve the visual color difference problem in the lower border area of ​​the display module.

[0004] An embodiment of this application provides a display module, including:

[0005] Backlight module;

[0006] The display panel is disposed on the light-emitting side of the backlight module. The display panel includes an array substrate and an opposing substrate. The opposing substrate is disposed on the side of the array substrate away from the backlight module. The array substrate includes a bonding portion.

[0007] A support substrate is disposed on the side of the array substrate away from the backlight module, and the support substrate and the opposing substrate are arranged side by side.

[0009] The second polarizer is disposed on the side of the supporting substrate away from the opposing substrate, and the second polarizer is arranged side by side with the first polarizer;

[0010] From a top-down view of the display module, at least a portion of the first polarizer overlaps with the supporting substrate and the bonding portion.

[0011] Furthermore, the display module also includes a first light-shielding layer, which is disposed between the support substrate and the array substrate.

[0012] Furthermore, the display module also includes a second light-shielding layer, which is disposed between the sidewall of the supporting substrate and the sidewall of the opposing substrate.

[0013] Furthermore, the material of the first light-shielding layer is black ink, and the material of the second light-shielding layer is black ink.

[0014] Furthermore, the surface of the supporting substrate away from the array substrate is flush with the surface of the opposing substrate away from the array substrate.

[0015] Furthermore, the surface of the second polarizer away from the array substrate is flush with the surface of the first polarizer away from the array substrate.

[0016] Furthermore, the material of the second polarizer is the same as that of the first polarizer.

[0017] Furthermore, the thickness of the second polarizer is the same as the thickness of the first polarizer.

[0018] Furthermore, the material of the supporting substrate is the same as the material of the opposing substrate.

[0019] Furthermore, a portion of the second polarizer extends toward the direction of the first polarizer, and the side of the second polarizer near the first polarizer contacts the side of the first polarizer near the second polarizer.

[0020] From a top-down view of the display module, a portion of the second polarizer overlaps with a portion of the opposing substrate.

[0021] The beneficial effects of this application are:

[0022] This application provides a display module comprising a support substrate, a first polarizer, and a second polarizer. The support substrate is disposed on the side of the array substrate away from the backlight module, and is arranged side-by-side with the opposing substrate. The first polarizer is disposed on the side of the opposing substrate away from the array substrate, and the second polarizer is disposed on the side of the support substrate away from the opposing substrate, and is arranged side-by-side with the first polarizer. From a top-view perspective of the display module, a portion of the first polarizer overlaps with the support substrate and the bonding portion. That is, the support substrate is disposed on the bonding portion of the display array substrate, and the second polarizer is correspondingly disposed on the support substrate. Compared with conventional solutions, the decorative strip in the lower bezel area of ​​the display module is eliminated, which can reduce the difference in structure between the lower bezel area of ​​the display module and the other bezel areas of the display module, improve the consistency of the structure of the lower bezel area of ​​the display module with the other bezel areas of the display module, and thus improve the visual color difference problem in the lower bezel area of ​​the display module.

[0029] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings. The technical solutions described below are for illustrative purposes only and should not be construed as limiting the scope of protection of this application.

[0030] Furthermore, the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different technical features. The terms "multiple" and similar words indicate two or more unless otherwise expressly specified.

[0031] Embodiments of this application provide a display module 10, with reference to... Figures 1-4The display module 10 includes a backlight module, a display panel 100, a support substrate 200, a first polarizer 300, and a second polarizer 400. The display panel 100 includes an array substrate 110 and an opposing substrate 120. The opposing substrate 120 is disposed on the side of the array substrate 110 away from the backlight module. The array substrate 110 includes a bonding portion 111. The opposing substrate 120 is disposed on the array substrate 110. The support substrate 200 is disposed on the side of the array substrate 110 away from the backlight module. The supporting substrate 200 and the opposing substrate 120 are arranged side by side; the first polarizer 300 is disposed on the side of the opposing substrate 120 away from the array substrate 110; the second polarizer 400 is disposed on the side of the supporting substrate 200 away from the opposing substrate 120, and the second polarizer 400 and the first polarizer 300 are arranged side by side; from a top view of the display module 10, a portion of the first polarizer 300 overlaps with the supporting substrate 200 and the bonding portion 111.

[0032] A decorative strip is provided on the bottom bezel of a conventional 3BL structure liquid crystal display module 10. Because the decorative strip on the bottom bezel of the liquid crystal display module 10 differs significantly from the top, left, and right bezels, a visual color difference occurs in the bottom bezel area. Therefore, this application provides a display module 10 that includes a support substrate 200, a first polarizer 300, and a second polarizer 400. The support substrate 200 is positioned on the side of the array substrate 110 away from the backlight module, and is arranged side-by-side with the opposing substrate 120. The first polarizer 300 is positioned on the side of the opposing substrate 120 away from the array substrate 110, and the second polarizer 400 is positioned on the side of the support substrate 200 away from the opposing substrate 120, and is arranged side-by-side with the first polarizer 300. The first polarizer 400 is positioned at a top view of the display module 10. A portion of 300 overlaps with the support substrate 200 and the bonding portion 111. That is, the support substrate 200 is provided on the bonding portion 111 of the display array substrate 110, and the second polarizer 400 is correspondingly provided on the support substrate 200. Compared with the conventional solution, the decorative strip of the lower border area of ​​the display module 10 is eliminated, which can reduce the difference between the structure of the lower border area of ​​the display module 10 and the structure of other border areas of the display module 10, improve the consistency between the structure of the lower border area of ​​the display module 10 and the structure of other border areas of the display module 10, thereby improving the visual color difference problem of the lower border area of ​​the display module 10, and realizing the 4BL (4Border Less) structure of the display module 10.

[0033] In this embodiment, the display module 10 includes a display area and a border area surrounding the display area. The border area includes an upper border area, a lower border area, a left border area, and a right border area.

[0034] In this embodiment, the bonding portion 111 of the array substrate 110 is located in the lower border area.

[0035] In this embodiment, the display module 10 has a 4BL (4Border Less) structure, that is, the top border area, bottom border area, left border area and right border area of ​​the display module 10 have an ultra-narrow border structure.

[0036] In this embodiment, the support substrate 200 is fixed to the bonding part 111 by adhesive.

[0037] In this embodiment, the display module 10 further includes a third polarizer 700, which is disposed on a surface of the array substrate 110 near the backlight module.

[0038] In this embodiment, the opposing substrate is a color filter substrate, that is, the color filter layer of the display panel is formed on the opposing substrate side. In another embodiment, the color filter layer may also be formed on the array substrate side.

[0039] In this embodiment, the display module 10 further includes a black matrix, which is disposed between the array substrate 110 and the opposing substrate 120. When viewed from above, the black matrix does not overlap with the bonding portion 111.

[0040] In this embodiment, reference Figure 2 The display module 10 further includes a first light-shielding layer 500, which is disposed between the support substrate 200 and the array substrate 110. Since a black matrix is ​​also provided between the array substrate 110 and the opposing substrate 120 of the display module 10, the area of ​​the second polarizer 400 corresponding to the display module 10 differs significantly from the area of ​​the first polarizer 300 corresponding to the display module 10. Therefore, the first light-shielding layer 500 is provided, which also serves to block light, thereby improving the consistency between the structure of the lower bezel area and the display area of ​​the display module 10, and reducing the visual difference between the lower bezel area and the display area of ​​the display module 10.

[0041] In this embodiment, the material of the first light-shielding layer 500 is light-shielding ink.

[0042] In this embodiment, the first light-shielding layer 500 is disposed on a surface of the support substrate 200 near the array substrate 110.

[0043] In this embodiment, reference Figure 2The display module 10 further includes a second light-shielding layer 600, which is disposed between the sidewall of the supporting substrate 200 and the sidewall of the opposing substrate 120. Because some of the light generated by the backlight module, when passing through the display panel 100, tends towards the area of ​​the display module 10 above the bonding portion 111, bright lines appear at the connection between the supporting substrate 200 and the opposing substrate 120, resulting in a noticeable visual difference in the display module 10. Therefore, by including the second light-shielding layer 600 between the sidewall of the supporting substrate 200 and the sidewall of the opposing substrate 120, the display module 10 can block a portion of the light generated by the backlight module from shining towards the area of ​​the display module 10 above the bonding portion 111, preventing bright lines from appearing at the connection between the supporting substrate 200 and the opposing substrate 120, and improving the visual effect of the display module 10.

[0044] In this embodiment, the material of the second light-shielding layer 600 is black ink.

[0045] In this embodiment, the second light-shielding layer 600 is disposed on a surface of the supporting substrate 200 near the opposing substrate 120.

[0046] In this embodiment, reference Figure 2 The surface of the support substrate 200 away from the array substrate 110 is flush with the surface of the opposing substrate 120 away from the array substrate 110. By setting the surface of the support substrate 200 away from the array substrate 110 and the surface of the opposing substrate 120 away from the array substrate 110 to be flush, it is beneficial to set the second polarizer 400, reducing the manufacturing difficulty of the display module 10. On the other hand, it can avoid the presence of a step difference at the junction of the support substrate 200 and the opposing substrate 120, which would cause abnormal appearance of the display module 10, thus improving the consistency of the appearance of the display module 10.

[0047] In this embodiment, the surface of the second polarizer 400 away from the array substrate 110 is flush with the surface of the first polarizer 300 away from the array substrate 110. By setting the surface of the second polarizer 400 away from the array substrate 110 to be flush with the surface of the first polarizer 300 away from the array substrate 110, it is possible to avoid any step difference at the junction of the first polarizer 300 and the second polarizer 400, which could cause abnormal appearance of the display module 10, thereby improving the consistency of the appearance of the display module 10.

[0048] In this embodiment, the material of the second polarizer 400 is the same as that of the first polarizer 300. By setting the material of the second polarizer 400 to be the same as that of the first polarizer 300, it is beneficial to improve the consistency of the light path L entering the second polarizer 400 and the light path L entering the first polarizer 300, thereby reducing the appearance difference of the display module 10.

[0049] In this embodiment, reference Figure 2 The thickness d1 of the second polarizer 400 is the same as the thickness d2 of the first polarizer 300. By setting the thickness d1 of the second polarizer 400 to be the same as the thickness d2 of the first polarizer 300, it is beneficial to improve the consistency of the light path L entering the second polarizer 400 and the light path L entering the first polarizer 300, thereby reducing the appearance difference of the display module 10.

[0050] In this embodiment, the material of the supporting substrate 200 is the same as the material of the opposing substrate 120. By using the same material for the supporting substrate 200 and the opposing substrate 120, the consistency between the light path L entering the supporting substrate 200 and the light path L entering the opposing substrate 120 is improved, thereby reducing the appearance differences of the display module 10.

[0051] In this embodiment, the second polarizer 400 and the first polarizer 300 are an integral structure.

[0052] In this embodiment, the second polarizer 400 and the first polarizer 300 are separate structures.

[0053] In this embodiment, reference Figure 2A portion of the second polarizer 400 extends toward the first polarizer 300, and a side of the second polarizer 400 near the first polarizer 300 contacts a side of the first polarizer 300 near the second polarizer 400; from a top view of the display module 10, a portion of the second polarizer 400 overlaps with a portion of the opposing substrate 120. Because conventional solutions show a certain gap between the edge of the first polarizer 300 of the display module 10 and the edge of the opposing substrate 120, if the second polarizer 400 is simply placed over the supporting substrate 200, meaning the edge of the second polarizer 400 near the display area of ​​the display module 10 is flush with the edge of the supporting substrate 200 near the opposing substrate 120, a gap exists between the first polarizer 300 and the second polarizer 400, resulting in a significant difference in the appearance of the display module 10. Therefore, by setting a portion of the second polarizer 400 to extend towards the first polarizer 300, and the side of the second polarizer 400 near the first polarizer 300 contacting the side of the first polarizer 300 near the second polarizer 400, from a top-view perspective of the display module 10, a portion of the second polarizer 400 overlaps with a portion of the opposing substrate 120, thus avoiding the difference in the appearance of the display module 10 caused by the gap between the second polarizer 400 and the first polarizer 300.

[0054] In this embodiment, the sidewall of the second polarizer 400 is fixed to the sidewall of the first polarizer 300 by transparent adhesive.

[0055] The specific embodiments of this application have been described in detail above. The embodiments disclosed above are merely preferred embodiments of this application. Those skilled in the art can make many modifications and improvements without departing from the concept of this application. All such modifications and improvements fall within the scope of protection defined by the claims of this application.
