DETAILED DESCRIPTION

[0034] In the display module provided by the related art, due to the lack of space on the side of the polarizer near the bending area, the bending protection material is easily accumulated on the side wall of the polarizer near the bending area, resulting in the bending protection layer being thicker at one end near the polarizer and thinner at other parts. The uneven thickness of the bending protection layer causes uneven stress on the metal traces superimposed on the bending protection layer, and even a sudden change in stress, resulting in the breakage of the metal traces.

[0035] In order to solve the above technical problems, this application is proposed. The present application provides a display module, which includes a display panel and a polarizer. The display panel includes a display area and a non-display area, and the non-display area is located at the periphery of the display area; the display panel also includes a straight area and a bending area, and the bending area is located at one end of the straight area. The straight area includes a display area and a part of the non-display area adjacent to the display area, and the other part of the non-display area is located in the bending area; the polarizer is stacked on the display side of the display panel, the polarizer at least covers the display area, and the distance between the boundary of the polarizer close to the bending area and the boundary of the bending area close to the straight area is greater than 100 microns, thereby providing more flow space for the bending protection material on the side of the polarizer close to the bending area, thereby improving the fluidity of the bending protection material and reducing the risk of the bending protection material accumulating on the side wall of the polarizer close to the bending area, thereby improving the uniformity of the flow of the bending protection material, thereby improving the uniformity of the thickness of the bending protection layer, and then improving the uniformity of the stress on the metal wiring stacked with the bending protection layer, thereby reducing the risk of the metal wiring in the bending area breaking due to uneven stress.

It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods and means well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0040] Figure 1 FIG. 1 is a schematic diagram of the structure of a display module provided by an embodiment of the present application. Figure 1 As shown, the display module 100 provided in the embodiment of the present application includes a display panel 110 and a polarizer 120, the display panel 110 includes a display area 11 and a non-display area 12, and the non-display area 12 is located at the periphery of the display area 11; the display panel 110 also includes a straight area 13 and a bending area 14, and the bending area 14 is located at one end of the straight area 13, and the straight area 13 includes the display area 11 and a part of the non-display area 12 adjacent to the display area 11, and another part of the non-display area 12 is located in the bending area 14; the polarizer 120 is stacked on the display side of the display panel 110, and the polarizer 120 at least covers the display area 11, and the distance d between the boundary of the polarizer 120 close to the bending area 14 and the boundary of the bending area 14 close to the straight area 13 is greater than 100 microns. Exemplarily, the distance d can be 120 microns, 150 microns, 170 microns, 200 microns, etc.

[0041] In the display module provided by the related technology, the distance between the boundary of the polarizer close to the bending area and the boundary of the bending area close to the straight area is less than or equal to 100 microns, resulting in insufficient space on the side of the polarizer close to the bending area, and the bending protection material is easily accumulated on the side wall of the polarizer close to the bending area.

[0042] Therefore, in the display module 100 provided in the embodiment of the present application, the distance d between the boundary of the polarizer 120 near the bending zone 14 and the boundary of the bending zone 14 near the straight zone 13 is greater than 100 microns, thereby providing more flow space for the bending protection material on the side of the polarizer 120 near the bending zone 14, thereby improving the fluidity of the bending protection material and reducing the risk of accumulation of the bending protection material on the side wall of the polarizer 120 near the bending zone 14, thereby improving the uniformity of the flow of the bending protection material, thereby improving the uniformity of the thickness of the bending protection layer 140, and further improving the uniformity of the stress on the metal wiring overlapped with the bending protection layer 140, thereby reducing the risk of breakage of the metal wiring in the bending zone 14 due to uneven stress.

[0043] Figure 2 FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present application. Figure 2 As shown, in the display module 100 provided in the embodiment of the present application, the distance d between the boundary of the polarizer 120 close to the bending area 14 and the boundary of the bending area 14 close to the straight area 13 is greater than 150 microns. Exemplarily, the distance d can be 160 microns, 170 microns, 180 microns, 190 microns or 200 microns, etc.

[0044] After in-depth research, the inventors found that the distance d between the boundary of the polarizer 120 close to the bending zone 14 and the boundary of the bending zone 14 close to the straight zone 13 is greater than 150 microns, which can provide sufficient flow space for the bending protection material and avoid the accumulation of the bending protection material on the side wall of the polarizer 120 close to the bending zone 14, thereby making the thickness of the bending protection layer 140 uniform, thereby further improving the uniformity of the stress on the metal wiring overlapped with the bending protection layer 140, and further reducing the risk of breakage of the metal wiring in the bending zone 14.

[0045] Figure 3 FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present application. Figure 3 As shown, in the display module 100 provided in the embodiment of the present application, the side wall of the polarizer 120 close to the bending zone 14 is a sloped side wall, thereby further increasing the flow space of the bending protection material, that is, increasing the flow path of the bending protection material, thereby further improving the fluidity of the bending protection material, and further reducing the risk of accumulation of the bending protection material on the side wall of the polarizer 120 close to the bending zone 14, thereby further improving the uniformity of the thickness of the bending protection layer 140, thereby further improving the uniformity of the stress on the metal wiring overlapped with the bending protection layer 140, thereby further reducing the risk of breakage of the metal wiring in the bending zone 14 due to uneven stress.

[0046] Preferably, the orthographic projection of the boundary of the sloped side wall close to the display panel 110 on the display panel 110 is located between the orthographic projection of the boundary of the sloped side wall away from the display panel 110 on the display panel 110 and the bending zone 14, that is, the orthographic projection of the top surface of the polarizer 120 away from the display panel 110 on the display panel 110 is located within the range of the orthographic projection of the bottom surface of the polarizer 120 close to the display panel 110 on the display panel 110, thereby increasing the flow path of the bending protection material by connecting the side walls of the top and bottom surfaces of the polarizer 120, thereby reducing the risk of accumulation of the bending protection material on the side walls of the polarizer 120 close to the bending zone 14, and at the same time reducing the risk of the bending protection material overflowing beyond the top surface of the polarizer 120.

[0047] Figure 4 FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present application. Figure 4 As shown, in the display module 100 provided in the embodiment of the present application, the boundary of the sloped side wall away from the display panel 110 is flush with the boundary of the display area 11 close to the bending area 14 (refer to Figure 4 ); or the slope sidewall is located away from the boundary of the display panel 110 and is located on the side of the display area 11 close to the bending area 14 (reference Figure 3 ), so that the portion of the polarizer 120 covering the display area 11 is of equal thickness, and the sloped side wall is located in the non-display area 12, thereby avoiding the problem that the sloped side wall (of unequal thickness) is located in the display area 11 and affects the display quality, that is, the embodiment of the present application improves the display quality.

[0048] Figure 5 FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present application. Figure 5 As shown, in the display module 100 provided in the embodiment of the present application, the display panel 110 also includes a touch layer 130, the touch layer 130 is located in the straight area 13, the orthographic projection of the polarizer 120 on the display panel 110 is located within the touch layer 130, and the edge of the touch layer 130 near the bending area 14 includes a groove.

[0049] The display module 100 provided in the embodiment of the present application utilizes grooves to provide more flow space for the bending protection material, thereby further improving the fluidity of the bending protection material, further reducing the risk of the bending protection material accumulating on the side wall of the polarizer 120 near the bending area 14, thereby further improving the uniformity of the flow of the bending protection material, thereby further improving the uniformity of the thickness of the bending protection layer 140, and further improving the uniformity of the stress on the metal wiring overlapped with the bending protection layer 140, thereby further reducing the risk of the metal wiring in the bending area 14 breaking due to uneven stress.

[0050] Preferably, the opening of the groove is opened on the surface of the touch layer 130 close to the polarizer 120, so that the bending protection material can be accommodated by the groove. The number of the grooves can be set according to actual needs.

[0051] refer to Figures 1 to 5 In the display module 100 provided in the embodiment of the present application, the display module 100 further includes a bending protection layer 140 , the bending protection layer 140 at least covers the bending area 14 , and the bending protection layer 140 is located on a side of the polarizer 120 close to the bending area 14 .

[0052] The bending protection layer 140 reduces the bending stress of the bending area 14 and prevents the corrosion of the internal film layer of the display module 100 by external water and oxygen.

[0053] Preferably, the bending protection layer 140 is stacked on the display side of the display panel 110 .

[0054] Figure 6 FIG. 2 is a schematic diagram of the structure of a display module provided by another embodiment of the present application. Figure 6 As shown, an embodiment of the present application provides a display module 100, which includes a display panel 110 and a polarizer 120. The display panel 110 includes a display area 11 and a non-display area 12, and the non-display area 12 is located at the periphery of the display area 11; the display panel 110 also includes a straight area 13 and a bending area 14, and the bending area 14 is located at one end of the straight area 13.

[0055] In the display module provided by the related technology, the positive projection of the boundary of the polarizer near the bending zone on the display panel is located on the side of the dam near the bending zone, resulting in insufficient space on the side of the polarizer near the bending zone, and the bending protection material is easily accumulated on the side wall of the polarizer near the bending zone.

[0056] Therefore, in the display module 100 provided in the embodiment of the present application, the orthographic projection of the boundary of the polarizer 120 near the bending zone 14 on the display panel 110 is located within the range of the dam 150, thereby providing more flow space for the bending protection material on the side of the polarizer 120 near the bending zone 14, thereby improving the fluidity of the bending protection material and reducing the risk of the bending protection material accumulating on the side wall of the polarizer 120 near the bending zone 14, thereby improving the uniformity of the flow of the bending protection material, thereby improving the uniformity of the thickness of the bending protection layer 140, and further improving the uniformity of the stress on the metal wiring superimposed on the bending protection layer 140, thereby reducing the risk of the metal wiring in the bending zone 14 being broken due to uneven stress. In addition, the embodiment of the present application avoids the light leakage phenomenon caused by the orthographic projection of the boundary of the polarizer 120 near the bending zone 14 on the display panel 110 being located on the side of the dam 150 near the display zone 11.

Figure 7 As shown, in the display module 100 provided in the embodiment of the present application, the side wall of the polarizer 120 close to the bending zone 14 is a sloped side wall, thereby further increasing the flow space of the bending protection material, that is, increasing the flow path of the bending protection material, thereby further improving the fluidity of the bending protection material, and further reducing the risk of accumulation of the bending protection material on the side wall of the polarizer 120 close to the bending zone 14, thereby further improving the uniformity of the thickness of the bending protection layer 140, thereby further improving the uniformity of the stress on the metal wiring overlapped with the bending protection layer 140, thereby further reducing the risk of breakage of the metal wiring in the bending zone 14 due to uneven stress.

[0058] Preferably, the orthographic projection of the boundary of the sloped side wall close to the display panel 110 on the display panel 110 is located between the orthographic projection of the boundary of the sloped side wall away from the display panel 110 on the display panel 110 and the boundary of the dam 150 close to the bending zone 14, that is, the orthographic projection of the top surface of the polarizer 120 away from the display panel 110 on the display panel 110 is located within the range of the orthographic projection of the bottom surface of the polarizer 120 close to the display panel 110 on the display panel 110, thereby increasing the flow path of the bending protection material by connecting the side walls of the top and bottom surfaces of the polarizer 120, thereby reducing the risk of accumulation of the bending protection material on the side walls of the polarizer 120 close to the bending zone 14, and at the same time reducing the risk of the bending protection material overflowing beyond the top surface of the polarizer 120.

[0060] In the display module provided by the related technology, the orthographic projection of the boundary of the touch layer near the bending zone on the substrate is located on the side of the orthographic projection of the dam on the substrate near the bending zone, resulting in insufficient space on the side of the polarizer near the bending zone, and the bending protection material is easily accumulated on the side wall of the polarizer near the bending zone.

[0061] Therefore, in the display module 100 provided in the embodiment of the present application, the orthographic projection of the boundary of the touch layer 130 near the bending zone 14 on the substrate 111 is located within the range of the orthographic projection of the dam 150 on the substrate 111, that is, the length of the touch layer 130 in the direction from the straight zone 13 to the bending zone 14 is shortened, thereby further increasing the flow space of the bending protection material, thereby further improving the fluidity of the bending protection material, and further reducing the risk of accumulation of the bending protection material on the side wall of the polarizer 120 near the bending zone 14, thereby further improving the uniformity of the thickness of the bending protection layer 140, thereby further improving the uniformity of the stress on the metal wiring overlapped with the bending protection layer 140, thereby further reducing the risk of breakage of the metal wiring in the bending zone 14 due to uneven stress.
