Description

Technical Field

[0001] The present disclosure relates to the field of display technologies, and in particular, to a display module, a display panel, and an electronic device. Background Art

[0002] In a display panel, a polarizer is generally disposed above a patterned panel to avoid the problem of glare. With the continuous improvement of display panel technologies, in order to make the display interface of the entire display panel integrated with the surrounding border as much as possible, a curved-edge display panel has become the mainstream. In order to achieve good display effects for the curved surfaces at the four corners of the display panel, the four corners of the display panel are generally patterned, and the patterns are strip-shaped patterns with gaps between them. However, due to the function of the polarizer, the reflectivity of the gaps is too high, affecting the integrated black efficiency of the display panel module and the visual comfort. Summary of the Invention

[0003] Embodiments of the present disclosure provide a display module, a display panel, and an electronic device to solve or alleviate one or more technical problems in the prior art.

[0004] As a first aspect of the embodiments of the present disclosure, the embodiments of the present disclosure provide a display module, including:

[0005] A polarizer;

[0006] A patterned panel disposed under the polarizer, and the patterns at the border corners thereof are multiple strip-shaped patterns with gaps between them; and

[0007] Multiple solid strips disposed between the polarizer and the patterned panel and respectively laid above or below each of the gaps between the multiple strip-shaped patterns; wherein, the orthographic projection of each solid strip in the multiple solid strips covers the orthographic projection of the corresponding gap.

[0011] In some possible implementations, when the plurality of entity strips are respectively laid above each gap between the plurality of strip-shaped patterns, the plurality of entity strips are embedded in the optical adhesive layer.

[0012] In some possible implementations, the pattern of the border corner of the optical adhesive layer is the same as the pattern of the border corner in the patterned panel that is in alignment.

[0035] In the following, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present disclosure. Therefore, the accompanying drawings and description are considered to be exemplary in nature rather than restrictive.

[0036] Figure 1 is a front view of a display module according to an embodiment of the present disclosure. Figure 2 is a cross-sectional view of a corner of a display module according to an embodiment of the present disclosure. Figure 3 is a cross-sectional view of a corner of a display module according to an embodiment of the present disclosure. Figure 4 is a cross-sectional view of a corner of a display module according to an embodiment of the present disclosure.

[0037] As Figures 1 to 4 shown, an embodiment of the present disclosure provides a display module, including a polarizer 101, a patterned panel 102, and a plurality of solid bars 104. As Figure 1 shown, since the polarizer 101 is transparent, the patterned panel 102 can be seen through the polarizer 101, wherein the four border corners of the patterned panel 102 also have corresponding patterns. The patterns at the four border corners of the panel are a plurality of strip patterns having gaps 103 therebetween. Figure 1 Only as an example, if the display module is triangular, then the patterned panel 102 is triangular, and it has three border corners. For the same patterned panel, the patterns at each border corner can be the same or different. The number of strip patterns 1021 at each border corner can be the same or different, and the shape of each strip pattern 1021 can be the same or different.

[0038] Figure 2 、 Figure 3 and Figure 4 are cross-sectional views at the dashed line a in a similar Figure 1 for different display modules. As Figure 2 shown, the patterned panel 102 is disposed under the polarizer 101, and the border corners of the patterned panel 102 have a plurality of strip patterns 1021, and there is a gap 103 between two adjacent strip patterns 1021. If light is directly irradiated onto the Figure 2 display module, the reflectivity of the gap 103 is too high, and the visual effect is poor, and the effect of the entire display module being integrally black cannot be achieved. As Figure 3 shown, the display module may further include a plurality of solid bars 104, which are disposed between the polarizer 101 and the patterned panel 102 and are respectively laid above each gap 103 between the plurality of strip patterns 1021. Or, as Figure 4As shown, a plurality of solid strips 104 are respectively laid below each gap 103 between a plurality of strip patterns 1021. The shapes of the solid strips 104 may be the same or different, and the shape mainly corresponds to the gap 103 in the patterned panel 102 opposite thereto. Moreover, the orthographic projection of each solid strip 104 covers the orthographic projection of the gap 103 opposite thereto. In this way, when light enters the display module, the reflectivity of the gap in the pattern at the border corner can be reduced.

[0039] Taking Figure 3 as an example, the orthographic projection shape of the strip pattern 1021 in the border corner of the panel is a regular quadrilateral, and the widths of the gaps 103 between the strip patterns 1021 may be the same, and the widths of the solid strips 104 may also be the same. In order to make the orthographic projection of the solid strip 104 cover the orthographic projection of the gap 103 opposite thereto, the width of the solid strip 104 is greater than or equal to the width of the gap 103. As Figure 5 shown, it shows the orthographic projection diagrams of two strip patterns 1021, the gap 103 therebetween, and the solid strip 104 opposite to the gap 103. From Figure 5 it can be seen that the solid strip 104 overlaps with the boundaries of the two strip patterns 1021, and the orthographic projection of the solid strip 104 covers the gap 103 between the two strip patterns 1021.

[0040] In actual application, the widths of the gaps 103 between the strip patterns 1021 may be different, and the widths of the strip patterns 1021 may also be different. The shapes between the strip patterns 1021 may be the same or different.

[0041] Exemplarily, the orthographic projection of the strip pattern 1021 may be in the shape of an irregular quadrilateral, triangle, sector, etc. As Figure 6 shown, it shows the structures in which the strip pattern 1021 may be an irregular quadrilateral or a sector. One side of the irregular quadrilateral may be a curved side.

[0042] In some embodiments, the display module may further include a support member 106 located below the patterned panel 102. The support member 106 is disposed opposite to the main body of the patterned panel 102, and it may not include components located below the border corners of the patterned panel 102, that is, it is empty. It may also include components located below the border corners of the patterned panel 102, and it may use the above-mentioned solid strip 104 located below the border corners of the panel as a part of the support member.

[0043] As Figure 7 shown, in the case where a plurality of solid strips 104 are respectively laid below each gap 103 between a plurality of strip patterns, some or all of the plurality of solid strips 104 are connected to the support member 106 for supporting the border corners of the patterned panel 102. Figure 4is a cross-sectional view at the dashed line a of Figure 7 The solid bar 104, as part of the support 106, is disposed below the border corner of the patterned panel 102, and the orthographic projection of each solid bar 104 covers the orthographic projection of its corresponding gap 103.

[0044] As Figure 8 shown, the orthographic projection of the support 106 only covers the main body of the patterned panel 102, not the border corners of the patterned panel 102. Then there are two ways to set the position of the solid bar 104: First, as Figure 3 shown, multiple solid bars 104 are disposed between the polarizer 101 and the patterned panel 102 and are respectively laid above each gap 103 between multiple strip patterns 1021. The solid bar 104 can be close to the patterned panel 102 or close to the polarizer 101. Second, as Figure 4 shown, multiple solid bars 104 are respectively laid below each gap 103 between multiple strip patterns 1021. For the same display module, a part of the border corners can be set according to Figure 3 , and another part of the border corners can be set according to Figure 4 . Or, all border corners can be set according to Figure 3 or Figure 4 .

[0045] In some embodiments, an optical glue paste layer 105 can also be disposed between the polarizer 101 and the patterned panel 102 for adhering the polarizer 101 and the patterned panel 102 together. The optical glue paste layer 105 can be patternless or patterned. Its pattern can be the same as or different from the pattern of the patterned panel 102.

[0046] Exemplarily, Figure 9 and Figure 10 are cross-sectional views at the dashed line a in a similar Figure 1 for different display modules. As Figure 9 shown, the optical glue paste layer 105 is patternless. Figure 10 has a pattern, and the pattern is the same as the pattern of the patterned panel 102. That is, the pattern of the border corners of the optical glue paste layer 105 is the same as the pattern of the corresponding border corners in the patterned panel 102. If the patterns of the border corners of the patterned panel 102 are the same, then the patterns of the border corners of the optical glue paste layer 105 are the same. If the patterns of the border corners of the patterned panel 102 are different, then the patterns of the border corners of the optical glue paste layer 105 are different.

[0047] Exemplarily, the optical glue paste layer 105 between the polarizer 101 and the patterned panel 102 can be one layer or multiple layers, and each layer adopts the same patterned design.

[0048] Exemplarily, as Figure 3 shown, in the case where a plurality of solid bars 104 are respectively laid above each gap 103 between a plurality of strip patterns, the plurality of solid bars 104 are embedded in the optical adhesive layer 105. All the solid bars 104 embedded in the optical adhesive layer 105 are close to the polarizer 101, or all the solid bars 104 are close to the patterned panel 102. A part of the solid bars 104 embedded in the optical adhesive layer 105 is close to the polarizer 101, and another part of the solid bars 104 is close to the patterned panel 102. The solid bars 104 in each frame corner can also be set similarly. For example, all the solid bars 104 in one frame corner are close to the polarizer 101, and all the solid bars 104 in another frame corner are close to the patterned panel 102. Again, for example, the solid bars 104 at all frame corners are close to the polarizer 101, or the solid bars 104 at all frame corners are close to the patterned panel 102.

[0049] In some embodiments, the coating material on at least the surface of the solid bar 104 close to the polarizer 101 is metal or oxide. As Figure 11 shown, the surface of the solid bar 104 close to the polarizer 101 or the entire outer surface is coated with a coating material 108 of metal or oxide, or the surfaces except the surface far from the polarizer 101 are coated with a coating material 108 of metal or oxide. The metal can be any elemental metal such as chromium, aluminum, iron, etc. The oxide can be aluminum oxide, silicon oxide, etc., which are not specifically limited here, and any coating with a reflection effect is within the protection scope of this patent.

[0050] In some embodiments, the coating material 108 of the solid bar 104 can be the same as or different from its body material. The coating materials 108 between the respective solid bars 104 can be the same or different. The body materials between the respective solid bars 104 can be the same or different.

[0051] Exemplarily, the body material of the solid bar 104 can be carbon fiber.

[0052] In some embodiments, the constituent material of the support 106 can be the same as or different from that of the solid bar 104.

[0053] Exemplarily, as Figure 11As shown, when the solid bar 104 is located below the patterned panel 102, the solid bar 104 can be part of a support or form an integrated design with the support member 106. The main material of the support member 106 is carbon fiber, and the coating material 108 on at least one side surface of the support member 106 close to the polarizer 101 is metal or oxide. The coating material 108 of metal or oxide is coated on the side surface of the support member 106 close to the polarizer 101 or the entire outer surface, or on the surface except the side surface far from the polarizer 101. The metal can be any elemental metal such as chromium, aluminum, iron, etc. The oxide can be aluminum oxide, silicon oxide, etc., and no specific limitation is made here. Any coating with a reflective effect is within the protection scope of this patent.

[0054] In some embodiments, the display template further includes a cover plate located above the polarizer 101. As Figure 2 , Figure 3 each Figure 4 shown, a cover plate 107 can be provided above the polarizer 101, and the orthographic projection of the cover plate 107 covers the orthographic projection of the polarizer 101.

[0055] In some embodiments, the border of the display module can be a curved edge, that is, the intersection of two planes is a curved edge when viewed from its cross-section. It can also be an edge border where two planes meet.
