DETAILED DESCRIPTION

[0041] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present disclosure, and different embodiments may be combined arbitrarily without conflict. Therefore, the drawings and descriptions are considered to be illustrative in nature and not restrictive.

[0042] The FLIT display product includes a first substrate and a second substrate arranged in a cell, for example, the first substrate may be an array substrate, and the second substrate may be a color filter substrate. In a FLIT display product, the second substrate is located at the light-emitting side of the display panel relative to the first substrate.

[0043] Figure 1 It is a plane diagram of the display panel in the FLIT product of the related technology. Figure 2 for Figure 1 AA cross-section diagram in Figure 2, Figure 3 for Figure 1 BB cross-section diagram in Figure 4 for Figure 1 Schematic diagram of CC cross section in FIG. In a FLIT product in the related art, the first substrate 10 is located on the light-emitting side of the display panel relative to the second substrate 20. For example, the first substrate 10 is an array substrate, the second substrate 20 is a color filter substrate, and the array substrate is located on the light-emitting side of the display panel. Figure 1-Figure 4 As shown, the side surface of the first substrate 10 facing the second substrate 20 is the first surface, and the electronic chip 11 is arranged on the first surface, and the electronic chip 11 is usually close to the first outer boundary 101 of the first substrate 10. Herein, the extension direction of the first outer boundary 101 is the first direction X, and the direction perpendicular to the first outer boundary 101 is the second direction Y.

[0044] like Figure 1 and Figure 3 As shown, a binding area is provided on the first surface along the first outer boundary, and the binding area needs to be bound and connected with the flexible circuit board 30. One end of the flexible circuit board 30 is connected to the binding area, and the other end is connected to the printed circuit board (PCB) 40. The second substrate 20 is arranged to be aligned with the first surface of the first substrate 10. In order to avoid the electronic chip 11 and the flexible circuit board 30 on the first substrate 10, the boundary of the second substrate 20 corresponding to the first outer boundary 101 is located on the surface of the first substrate 10, that is, the size of the second substrate 20 in the second direction Y is smaller than the size of the first substrate 10 in the second direction Y, so that the electronic chip 11 and the flexible circuit board 30 will not be covered by the second substrate 20, that is, the second substrate 20 avoids the electronic chip 11 and the flexible circuit board 30.

[0045] like Figure 2-Figure 4 As shown, the display panel further includes a first polarizer 31 and a second polarizer 32. The second polarizer 32 is attached to the side of the first substrate 10 that is away from the second substrate 20. The first polarizer 31 is attached to the side of the second substrate 20 that is away from the first substrate 10. The outer boundary of the first polarizer 31 is usually located inside the outer boundary of the second substrate 20.

[0046] When the first substrate 10 is located at the light emitting side of the display panel relative to the second substrate 20, the force-bearing surface of the display panel for receiving the supporting force is the lower surface of the display panel. Figure 2-Figure 4 As shown. Due to the arrangement of the electronic chip 11 and the flexible circuit board 30 and the size of the first polarizer 31 being smaller than the size of the second substrate 20, the lower surface of the display panel is not a flat surface. Figure 2-Figure 4 It can be seen that there are multiple steps on the lower surface of the display panel.

[0047] refer to Fig.14 , because there are multiple steps on the lower surface of the display panel, such as Fig.14In the embodiment, the lower surface of the first substrate 10, the lower surface of the electronic chip 11, and the lower surface of the second substrate 20 are not on the same plane. In order to support the display panel, the support surface for supporting the display panel needs to be provided with a structure matching the lower surface of the display panel to support the display panel. For example, a second fixing tape 64 with a special-shaped structure is provided on the lower side of the display panel. Such a module, because the display panel is supported by a second fixing tape with a special-shaped structure, is prone to uneven force on the display panel during a pressure test or a torsion test or even during an assembly process, resulting in defective fragmentation of the first substrate 10 or the second substrate 20 in the display panel.

[0048] In order to solve some problems in the related art, an embodiment of the present disclosure provides a display module.

[0049] Figure 5 is a schematic plan view of a display panel in an embodiment of the present disclosure, Figure 6 for Figure 5 AA section diagram in; Figure 7 for Figure 5 BB cross-section diagram in; Figure 8 for Figure 5 Schematic diagram of CC section in. Figure 5-Figure 8 As shown, the display module includes a display panel and a backlight module, and the display panel includes a first substrate 10 and a second substrate 20. Exemplarily, the first substrate 10 may include an array substrate, and the second substrate 20 may include a color filter substrate. An electronic chip 11 is disposed on the first surface of the first substrate 10, and the electronic chip 11 is close to the first outer boundary of the first substrate 10. Exemplarily, the first substrate 10 may be a quadrilateral, and the first outer boundary may be one of the four outer boundaries of the first substrate 10.

[0050] The second substrate 20 is disposed in alignment with the first surface of the first substrate 10 . The outer boundary of the second substrate 20 is flush with the outer boundary of the first substrate 10 .

[0051] Fig. 9 is a schematic plan view of a substrate. Herein, the outer boundary of the substrate should be understood as the boundary of the entire range occupied by the substrate. Fig. 9 As shown, the substrate is a quadrilateral as a whole. Even if a via hole K is opened on the substrate or a notch S is opened along a boundary of the substrate, the edge of the via hole K or the notch S does not constitute the outer boundary of the substrate, and the outer boundary of the substrate is still the outer boundary 100 of the quadrilateral.

[0052] like Figure 6As shown, the second substrate 20 is provided with a hollow 21, and the orthographic projection of the electronic chip 11 on the first substrate 10 is located within the orthographic projection of the hollow 21 on the first substrate 10. Thus, the second substrate 20 can avoid the electronic chip 11 through the hollow 21. Exemplarily, the hollow 21 can correspond to the electronic chip 11 one by one, and the orthographic projection of the electronic chip 11 on the first substrate 10 is located within the orthographic projection of the corresponding hollow 21 on the first substrate 10. In other embodiments, two or more electronic chips 11 may correspond to one hollow 21. Exemplarily, the second substrate 20 is arranged between the electronic chip 11 and the first outer boundary 101, and a portion of the second substrate 20 is located between the electronic chip 11 and the first outer boundary 101.

[0053] Fig.10 is a plan view of a display module. Fig.11 for Fig.10 The DD cross-sectional view of the display module in one embodiment of the present disclosure is shown. Fig.12 for Fig.10 The EE cross-sectional view of the display module in one embodiment of the present disclosure is shown. Figure 10-12 As shown, the display module also includes a backlight module, which is located on the side of the second substrate 20 away from the first substrate 10. The backlight module is used to support the surface of the display panel facing the second substrate 20, that is, the backlight module is used to support the lower surface of the display panel.

[0054] In related technologies, such as Figure 2-Figure 4 As shown, the lower surface of the display panel is not a flat surface, and there are multiple steps on the lower surface of the display panel. In order to support the display panel, the support surface for supporting the display panel in the backlight module needs to be provided with a structure matching the lower surface of the display panel to support the display panel. Such a module is prone to uneven force on the display panel during the pressure test or torsion test or even during the assembly process, resulting in defective fragmentation of the first substrate 10 or the second substrate 20.

[0055] In the embodiment of the present disclosure, the outer boundary of the second substrate 20 is flush with the outer boundary of the first substrate 10, the second substrate 20 is provided with a hollow 21, and the orthographic projection of the electronic chip 11 on the first substrate 10 is located within the orthographic projection of the hollow 21 on the first substrate 10. Such a structure increases the area of ​​the second substrate 20 relative to the related art, so that the outer boundary of the second substrate 20 is flush with the outer boundary of the first substrate 10, thereby improving the strength of the display panel.

[0056] In the embodiment of the present disclosure, the force-bearing surface of the display panel is the outer surface of the display panel facing the second substrate 20. Figure 6-Figure 8The lower surface of the display panel in the backlight module. Since the outer boundary of the second substrate 20 is flush with the outer boundary of the first substrate 10, and the surface of the second substrate 20 facing away from the first substrate 10 is a flat surface, the force-bearing surface of the display panel is a flat surface, so that the support surface of the backlight module for supporting the display panel can also be a flat surface. The flat surface of the backlight module supports the flat surface of the display panel, which can ensure that the display panel is evenly stressed during the pressure test or the torsion test process and even during the assembly process, improve the first substrate 10 and the second substrate 20 in the display panel. Fragmentation defects and reduce the incidence of fragmentation.

[0057] In addition, the outer boundary of the second substrate 20 is flush with the outer boundary of the first substrate 10, and the second substrate 20 is provided with a hollow 21 to avoid the electronic chip 11. Thus, the second substrate 20 is also arranged between the electronic chip 11 and the first outer boundary 101 of the first substrate 10. Then, when the backlight module supports the display panel, the backlight module can be supported on the surface of the second substrate 20 without direct contact with the first substrate 10, thereby further avoiding the defect of the first substrate 10 being broken.

[0058] In one embodiment, Figure 6 As shown, the distance d1 between the orthographic projection boundary of the electronic chip 11 on the first substrate 10 and the orthographic projection boundary of the hollow 21 on the first substrate 10 is greater than or equal to 0.5 mm. When the distance d1 is set to be greater than or equal to 0.5 mm, even if there is an alignment error between the first substrate 10 and the second substrate 20, the second substrate 20 can completely avoid the electronic chip 11 through the hollow 21.

[0059] In one embodiment, Figure 5 and Figure 7 As shown, a binding area is provided on the first surface along the first outer boundary. The display module further includes a flexible circuit board 30, and the flexible circuit board 30 is bound and connected to the binding area. There is a first overlapping area between the flexible circuit board 30 and the first substrate 10. The second substrate 20 is provided with a notch 22, and the first overlapping area is located within the orthographic projection of the notch 22 on the first substrate 10, so that the notch 22 can avoid the flexible display panel.

[0060] In related technologies, such as Figure 1 and Figure 3 As shown, the size of the second substrate 20 in the second direction Y is smaller than the size of the first substrate 10 in the second direction Y, so that after the second substrate 20 is aligned with the first substrate 10, the second substrate 20 is located outside the binding area, so that the second substrate 20 avoids the flexible circuit board 30. In the related art, the size of the second substrate 20 in the second direction Y is smaller than the size of the first substrate 10 in the second direction Y, so that the area of ​​the second substrate 20 is much smaller than the area of ​​the first substrate 10, which reduces the strength of the display panel.

[0061] In this embodiment, Figure 5 and Figure 7 As shown, the outer boundary of the second substrate 20 is flush with the outer boundary of the first substrate 10, and a notch 22 is provided on the second substrate 20 to avoid the flexible circuit board 30. In this way, the area of ​​the second substrate 20 is greatly increased. Therefore, when the second substrate 20 is aligned with the first substrate 10, the strength of the display panel can be further improved, and the defect of breakage of the first substrate 10 and the second substrate 20 can be reduced.

[0062] like Figure 7 As shown, the distance d2 between the boundary of the first overlapping area and the orthographic projection boundary of the notch 22 on the first substrate 10 is greater than or equal to 0.7 mm. Figure 3 As shown, the distance between the boundary of the flexible circuit board 30 close to the second substrate 20 and the second substrate 20 is greater than or equal to 2 mm. In this embodiment, the distance between the boundary of the flexible circuit board 30 close to the second substrate 20 and the second substrate 20, i.e., the distance d2, is greater than or equal to 0.7 mm, and such d2 is much smaller than d3, which greatly increases the matching area of ​​the second substrate 20 and the first substrate 10, and improves the strength of the display panel.

[0063] like Figure 6-Figure 8 As shown, the display panel may further include a first polarizer 31, and the first polarizer 31 is attached to the surface of the second substrate 20 on the side facing away from the first substrate 10. The orthographic projection of the first polarizer 31 on the first substrate 10 coincides with the orthographic projection of the second substrate 20 on the first substrate 10. The backlight module is supported on the side of the first polarizer 31 facing away from the first substrate 10. In such a structure, when the backlight module is supported on the side of the second substrate 20 facing away from the first substrate 10, as shown in FIG. Fig.11 and Fig.12 As shown, the backlight module is supported on the side of the first polarizer 31 away from the first substrate 10, so that the backlight module contacts the first polarizer 31 but does not contact the second substrate 20. Therefore, the backlight module applies a supporting force to the second substrate 20 through the first polarizer 31. Under the buffering effect of the first polarizer 31, the second supporting force applied by the backlight module to the second substrate 20 is more uniform, which is beneficial to protecting the first substrate 10 and the second substrate 20, and further reducing the first substrate 10 and the second substrate 20 from being broken.

[0064] In one embodiment, the distance between the surface of the electronic chip 11 away from the first substrate 10 and the first substrate 10 is smaller than the distance between the surface of the first polarizer 31 away from the first substrate 10 and the first substrate 10. Fig.11In the embodiment, the lower surface of the first polarizer 31 is lower than the lower surface of the electronic chip 11. Therefore, the force-bearing surface of the display panel is on the lower surface of the first polarizer 31, and the lower surface of the first polarizer 31 is a flat surface, that is, the force-bearing surface of the display panel is a flat surface.

[0065] Fig.13 FIG. 1 is a schematic plan view of the assembly structure of the display panel and the back panel in one embodiment. Fig.11 and Fig.13 As shown, the backlight module includes a back plate 40 and a support sheet 62. The side of the back plate 40 facing the display panel is provided with a receiving cavity and a support end surface 41 arranged along the circumference of the receiving cavity. The support end surface 41 includes a first end surface 411, and the first end surface 411 corresponds to the first outer boundary 101. That is, the first outer boundary 101 of the display panel is on the first end surface 411. The support sheet 62 is attached to the first end surface 411, and the first polarizer 31 is in contact with the surface of the support sheet 62 away from the back plate 40. Therefore, the back plate 40 supports the lower surface of the first polarizer 31 through the support sheet 62, thereby supporting the display panel.

[0066] Exemplarily, the support sheet 62 may be fixed to the first end surface portion 411 by a first fixing tape 61 .

[0067] Fig.14 for Fig.10 The DD cross-sectional view of the display module in the related art is shown. In the related art, since there are multiple steps on the lower surface of the display panel, for example, Fig.14 In the embodiment, the lower surface of the first substrate 10, the lower surface of the electronic chip 11, and the lower surface of the second substrate 20 are not on the same plane. In order to support the display panel, the support structure between the support end surface 41 of the back plate 40 and the display panel includes a support sheet 62, and the support sheet 62 is fixed to the first end surface 411 by a first fixing tape 61. In order to make up for the step difference of the lower surface of the display panel, a second fixing tape 64 is also required to be provided between the support sheet 62 and the display panel, and the second fixing tape 64 is a special-shaped structure. Therefore, in the related art, the support structure between the support end surface 41 and the display panel includes the first fixing tape 61, the support sheet 62, and the second fixing tape 64 of the special-shaped structure.

[0068] In the display module of the embodiment of the present disclosure, the force-bearing surface of the display panel is a flat surface, and the flat surface of the support sheet 62 can directly fit the force-bearing surface of the display panel to support the display panel. Therefore, the support structure in the display module of the embodiment of the present disclosure includes the first fixing tape 61 and the support sheet 62. Fig.14As shown in the related technology, the display module of the embodiment of the present disclosure no longer needs a second fixing tape 64 with a special-shaped structure in the supporting structure, so the supporting structure is simpler, and the flat surface of the supporting sheet 62 directly supports the force-bearing surface of the display panel, thereby obtaining a better supporting effect.

[0069] For example, Fig.11 As shown, the orthographic projection of the hollow 21 on the first substrate 10 is located within the orthographic projection of the support sheet 62 on the first substrate 10, and there is a first preset distance between the orthographic projection boundary of the hollow 21 on the first substrate 10 and the orthographic projection boundary of the support sheet 62 on the first substrate 10, the first preset distance is greater than 0, and the specific value of the first preset distance can be set as needed. Thus, the support sheet 62 supports the lower surface of the first polarizer 31 around the hollow 21, expanding the support area of ​​the support sheet 62 for the display panel, and playing a better supporting role for the display panel; and the electronic chip 11 is located in the closed space surrounded by the hollow 21 and the support sheet 62, which plays a good protective role for the electronic chip 11.

[0070] In one embodiment, Fig.11 and Fig.13 As shown, the back plate 40 also includes a protective wall 42 arranged around the outer periphery of the support end surface 41, and the protective wall 42 can protect the display panel inside. The protective wall 42 can be provided with a perforation for the flexible circuit board 30 to pass through. The flexible circuit board 30 passes through the perforation and is connected to the printed circuit board 70 (PCB). Fig.10 Schematic diagram of the placement area M of the printed circuit board 70 is shown in FIG.

[0071] In one embodiment, the support end surface 41 further includes a second end surface 412 outside the first end surface 411. At the second end surface 412, the first polarizer 31 is attached to the second end surface 412 by a fixing tape. For example, FIG. Fig.12 The middle 61 and 63 can be a fixing tape with an integral special-shaped structure.

[0072] In one embodiment, Fig.12 and Fig.13 As shown, the shape of the support sheet 62 can match the shape of the support end face 41. For example, the support end face 41 is a quadrilateral strip, and the support sheet 62 can also be a quadrilateral strip. The support sheet 62 is attached to the support end face 41. The first polarizer 31 is located on the upper surface of the support sheet 62. Thus, the support sheet 62 can provide support for the display panel in the circumferential direction of the display panel, thereby improving the stability of the support. In such a structure, the support structure of the display panel in the circumferential direction is an integrated support sheet. When assembling the display module, after the support sheet 62 is attached to the support end face 41 by a fixing tape, the display panel is placed on the support sheet 62, which simplifies the structure and assembly process of the display module.

[0073] like Fig.11 and Fig.12 As shown, the support sheet 62 includes a protrusion protruding from the support end surface 41 toward the accommodating cavity. A light shielding tape 63 is provided on one side of the protrusion facing the accommodating cavity. The light shielding tape 63 can be used to shield light and prevent light from leaking from the hollow 21.

[0074] like Fig.11 and Fig.12 As shown, the backlight module may further include a backlight unit, and the backlight unit may be located in the accommodation cavity. Exemplarily, the backlight unit may include a light source and an optical film material 55 located on the light emitting side of the light source.

[0075] exist Fig.11 and Fig.12 In the embodiment, the light source may include a light bar 56, a light guide plate 54, a reflective sheet 53 located below the light guide plate 54, and a support body 52 located below the reflective sheet 53. The support body 52 may be made of foam. The optical film material 55 may include a first diffuser, a first prism, a second prism, and a second diffuser arranged in a stacked manner.
