DETAILED DESCRIPTION

[0034] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. And the embodiments in the present application and the features in the embodiments can be combined with each other without conflict, if necessary. Based on the described embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the protection scope of the present application.

The terms "inner", "outer", "upper", "lower" and similar words are used to indicate relative positions only, and when the absolute positions of the described objects are changed, the relative positions may also be changed accordingly.

[0036] It should be noted that the sizes and shapes of the figures in the drawings do not reflect true proportions, but only serve to illustrate the content of the present application. And the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout the drawings.

[0037] In the related art, after the completion of the box, the frame glue is necessarily in contact with the liquid crystal, and the area where the liquid crystal is in contact with the inner edge of the frame glue is arranged in disorder, thereby causing light leakage in the L0 state. Once there is an area range not covered by the BM on the DPO side, the light leakage is likely to be visible at the normal viewing angle, thereby causing the problem of edge bright line on the DPO side.

[0038] In view of this, the embodiments of the present application provide a display panel and a display device to avoid the problem of edge bright line on the DPO side and improve the display effect.

[0039] In combination with Figure 1 and Figure 2 , wherein, Figure 1 is a schematic top view of one of the display panels provided by the embodiments of the present application, Figure 2 is a schematic cross-sectional view in the direction indicated by MM in Figure 1 . Specifically, the display panel comprises:

[0040] oppositely arranged opposite substrate 10 and display substrate 20, and liquid crystal layer 30 located between the opposite substrate 10 and the display substrate 20;

[0041] The display substrate 20 comprises a display area A and a non-display area B surrounding the display area A, and the non-display area B comprises a binding area B1 and an opposite area B2 arranged oppositely; the display panel further comprises a shielding structure 40, and the orthogonal projection of the shielding structure 40 on the display substrate 20 covers the opposite area B2.

[0042] In the specific implementation process, the display panel comprises oppositely arranged opposite substrate 10 and display substrate 20, and liquid crystal layer 30 located between the opposite substrate 10 and the display substrate 20. For example, the opposite substrate 10 is a color filter (CF) substrate, and the display substrate 20 is a thin film transistor (TFT) substrate. Moreover, the display substrate 20 comprises a display area A and a non-display area B surrounding the display area A, and the non-display area B comprises a binding area B1 and an opposite area B2 arranged oppositely. The binding area B1 is the data pad (DP) side of the display substrate 20, i.e. the side where the data signal external circuit is attached. The opposite area B2 is the opposite side of the DP side, i.e. the DPO side. As Figure 1 is a schematic distribution diagram of the display area A, the non-display area B, the binding area B1 and the opposite area B2. Of course, the distribution of the display area A, the non-display area B, the binding area B1 and the opposite area B2 can also be set according to actual application needs, which is not limited herein.

[0043] In addition, the display panel also includes a shielding structure 40, the orthographic projection of which covers the opposing area B2 on the display substrate 20. In this way, the opposing area B2 is shielded by the shielding structure 40. Even if light leakage occurs in the opposing area B2 in the L0 state after cell assembly, the light leakage problem is effectively avoided due to the shielding structure 40, thus preventing bright lines at the edge on the DPO side and ensuring display quality.

[0044] It should be noted that the display panel provided in this embodiment of the invention also includes a plurality of support posts 50 disposed between the opposing substrate 10 and the display substrate 20. Exemplarily, the support posts 50 are post spacer bars (PS bars). The specific number and distribution of the plurality of support posts 50 can be set according to actual application needs and are not limited here.

[0045] In this embodiment of the invention, the shielding structure 40 can be configured in several ways, but is not limited to these.

[0046] For example, in combination Figures 3 to 8 As shown along Figure 1 A cross-sectional view of the structure shown in the NN direction is provided. The shielding structure 40 is disposed on the side of the opposing substrate 10 away from the liquid crystal layer 30, and / or on the side of the display substrate 20 away from the liquid crystal layer 30. In this way, on the one hand, the shielding structure 40 effectively blocks the light from the opposing region B2, avoiding the problem of bright lines at the edge on the DPO side; on the other hand, since the shielding structure 40 is disposed on the side of the opposing substrate 10 away from the liquid crystal layer 30, and / or on the side of the display substrate 20 away from the liquid crystal layer 30, even if the shielding structure 40 becomes statically charged due to static electricity from the external environment, it will not affect the arrangement of the liquid crystal layer 30, thereby avoiding the problem of greening in the L0 state caused by the shielding structure 40 being charged, and improving the display effect.

[0047] exist Figure 3 In the exemplary embodiment shown, the shielding structure 40 is disposed on the side of the opposing substrate 10 away from the liquid crystal layer 30.

[0048] exist Figure 4 In the exemplary embodiment shown, the shielding structure 40 is disposed on the side of the display substrate 20 away from the liquid crystal layer 30.

[0049] exist Figure 5 In the exemplary embodiment shown, the shielding structure 40 is disposed on the side of the opposing substrate 10 away from the liquid crystal layer 30, and on the side of the display substrate 20 away from the liquid crystal layer 30.

[0050] It should be noted that, in Figures 3 to 5In the exemplary embodiment shown, the shielding structure 40 can be at least one of BM, black ink, and black tape. Of course, the specific material of the shielding structure 40 can be set according to actual application needs, and is not limited here. In one exemplary embodiment, black tape can be attached to the DPO side of the opposing substrate 10 away from the liquid crystal layer 30 for light shielding. For example, for a 58.5-inch product, the width of the black tape ranges from 5.5mm to 7.5mm.

[0051] In practical implementation, the specific width of the shielding structure 40 can be set according to the actual light-shielding effect required by the display panel for the DPO side based on the specific structural parameters. In actual research, the inventors found that for a 58.5-inch product, the distance from the inner edge of the bezel adhesive surrounding the liquid crystal layer 30 between the opposing substrate 10 and the display substrate 20 to the DPO side is 5.5mm, and the distance between the display area A and the DPO side is 7.5mm. For example, a strip of BM or black ink with a width ranging from 5.5mm to 7.5mm can be applied to the DPO side of the opposing substrate 10 and / or the display substrate 20 to serve as the shielding structure 40. This shielding structure 40 can be placed on the outer side of the display panel, thereby shielding the DPO side from light and avoiding bright lines at the edge of the DPO side, ensuring display quality. Of course, the specific width of the shielding structure 40 can also be set according to actual application needs, and is not limited here.

[0052] For example, in combination Figures 6 to 8 As shown along Figure 1 A cross-sectional structural diagram in the direction shown in the diagram; the blocking structure 40 includes a first polarizer 41 and a second polarizer 42 stacked together, wherein the polarization direction of the first polarizer 41 and the polarization direction of the second polarizer 42 are perpendicular to each other.

[0053] In the specific implementation process, the first polarizer 41 is located between the second polarizer 42 and the liquid crystal layer 30. The orthographic projection of the second polarizer 42 on the display substrate 20 covers the display area A and the non-display area B. The second polarizer 42 is multiplexed as an upper polarizer 60 or a lower polarizer 70. The orthographic projection of the first polarizer 41 on the display substrate 20 covers the opposing area B2.

[0054] exist Figure 6In the illustrated example embodiment, the shielding structure 40 is arranged on the side of the counter substrate 10 facing away from the liquid crystal layer 30, and the shielding structure 40 comprises a first polarizer 41 and a second polarizer 42 arranged in a stack, the first polarizer 41 being located between the second polarizer 42 and the liquid crystal layer 30, and the second polarizer 42 being reused as the upper polarizer 60; wherein the polarization direction of the first polarizer 41 is perpendicular to the polarization direction of the second polarizer 42, and the orthogonal projection of the second polarizer 42 on the display substrate 20 covers the display area A and the non-display area B, and the orthogonal projection of the first polarizer 41 on the display substrate 20 covers the counter area B2. For example, for a product of 58.5 inches, the width of the first polarizer 41 ranges from 5.5 mm to 7.5 mm. It should be noted that in this example embodiment, since the polarization direction of the first polarizer 41 is perpendicular to the polarization direction of the second polarizer 42, the light shielding effect can be achieved in the L0 state when the two are stacked together, thereby ensuring the display effect.

[0055] In Figure 7 In the illustrated example embodiment, the shielding structure 40 is arranged on the side of the display substrate 20 facing away from the liquid crystal layer 30, and the shielding structure 40 comprises a first polarizer 41 and a second polarizer 42 arranged in a stack, the first polarizer 41 being located between the second polarizer 42 and the liquid crystal layer 30, and the second polarizer 42 being reused as the lower polarizer 70; wherein the polarization direction of the first polarizer 41 is perpendicular to the polarization direction of the second polarizer 42, and the orthogonal projection of the second polarizer 42 on the display substrate 20 covers the display area A and the non-display area B, and the orthogonal projection of the first polarizer 41 on the display substrate 20 covers the counter area B2. For example, for a product of 58.5 inches, the width of the first polarizer 41 ranges from 5.5 mm to 7.5 mm. It should be noted that in this example embodiment, since the polarization direction of the first polarizer 41 is perpendicular to the polarization direction of the second polarizer 42, the light shielding effect can be achieved in the L0 state when the two are stacked together, thereby ensuring the display effect.

[0056] In Figure 8 In the illustrated example embodiment, the shielding structure 40 comprises a portion arranged on the side of the counter substrate 10 facing away from the liquid crystal layer 30, and a portion arranged on the side of the display substrate 20 facing away from the liquid crystal layer 30; each of the two portions comprises two polarizers arranged in a stack, wherein the second polarizer 42 in the portion arranged on the side of the counter substrate 10 facing away from the liquid crystal layer 30 is reused as the upper polarizer 60; and the second polarizer 42 in the portion arranged on the side of the display substrate 20 facing away from the liquid crystal layer 30 is reused as the lower polarizer 70. In actual application, the specific position of the shielding structure 40 on the counter substrate 10 and the display substrate 20 can be set according to the need for light shielding effect, which is not limited herein.

[0057] For example, the display panel further includes an upper polarizer 60 located on the side of the opposing substrate 10 away from the liquid crystal layer 30, and a lower polarizer 70 located on the side of the display substrate 20 away from the liquid crystal layer 30. The blocking structure 40 is disposed on the side of the upper polarizer 60 and / or the lower polarizer 70 near the liquid crystal layer 30. In one exemplary embodiment, the blocking structure 40 is a black matrix and is disposed around the display area A; in this exemplary embodiment, for a 58.5-inch product, the width of the black matrix on the DPO side ranges from 5.5mm to 7.5mm.

[0058] like Figure 9 The following is along Figure 1 This is a schematic diagram of one cross-sectional structure along the MM direction. In this exemplary embodiment, the display panel further includes an upper polarizer 60 located on the side of the opposing substrate 10 away from the liquid crystal layer 30, and a lower polarizer 70 located on the side of the display substrate 20 away from the liquid crystal layer 30. A shielding structure 40 is disposed on the side of the upper polarizer 60 near the liquid crystal layer 30. In a specific implementation, the shielding structure 40 can be integrated with the upper polarizer 60. For example, BM adhesive is coated on the upper polarizer 60, and then after exposure and development by masking, only the peripheral area is retained, thereby integrating the corresponding BM in the peripheral area of ​​the upper polarizer 60. Figure 10 As shown Figure 9 A top view schematic diagram of one type of shielding structure 40 integrated into the upper polarizer 60.

[0059] Apart from Figure 9 In addition to the exemplary embodiments shown, the blocking structure 40 can also be integrated with the lower polarizer 70, or the blocking structure 40 can be integrated onto both the upper polarizer 60 and the lower polarizer 70. Of course, those skilled in the art can integrate the blocking structure 40 according to actual application needs, and no limitation is made here.

[0060] For example, such as Figure 11 The following is along Figure 1 The diagram shows one type of cross-sectional structure in the direction shown in Figure OO. Specifically, the shielding structure 40 is disposed between the opposing substrate 10 and the display substrate 20, and in the region corresponding to the opposing region B2, the opposing substrate 10, the display substrate 20, and the shielding structure 40 are disposed flush with each other.

[0061] The inventor found in actual research that, taking the shielding structure 40 as an example, the BM is exposed twice on the DPO side, and then is edge-aligned cut. Since the BM mask baffle moving position is limited, after the BM is exposed once, the DPO side has no BM in a width of 7.5 mm; then, by moving the position of the substrate, the BM is exposed twice to form a 7.5 mm wide BM on the DPO side. Since the BM is edge-aligned with the substrate, the electrostatic from the external environment makes the BM charged, and the green emission failure in the L0 state occurs.

[0062] In the embodiment of the present application, as shown in Figure 12 is a schematic diagram of one of the cross-sectional structures along the direction shown in Figure 1 Specifically, the display panel further comprises an upper polarizer 60 located on the side of the counter substrate 10 away from the liquid crystal layer 30, and a lower polarizer 70 located on the side of the display substrate 20 away from the liquid crystal layer 30, the upper polarizer 60 and the lower polarizer 70 are edge-aligned arranged in the area corresponding to the counter area B2, and the side of the counter substrate 10, the display substrate 20 and the shielding structure 40 close to the counter area B2, and the side of the upper polarizer 60 and the lower polarizer 70 close to the counter area B2 form a containing space Q (as shown in the dotted box in Figure 12 The display panel further comprises an insulating glue 80 arranged in the containing space Q, and the side of the insulating glue 80 away from the counter area B2 is edge-aligned arranged with the side of the upper polarizer 60 and the lower polarizer 70 close to the counter area B2.

[0063] For example, in the area corresponding to the counter area B2, the distance range of the upper polarizer 60 beyond the counter substrate 10 is 1 mm to 2 mm, the distance range of the lower polarizer 70 beyond the display substrate 20 is 1 mm to 2 mm, and the thickness range of the insulating glue 80 is 1 mm to 2 mm. In this way, the electrostatic effect of the external environment is effectively isolated by the insulating glue 80, the shielding structure 40 is prevented from being charged, and the green emission failure in the L0 state on the DPO side is avoided.

[0064] In the embodiment of the present application, the liquid crystal layer 30 is composed of negative liquid crystal molecules.

[0065] In one of the exemplary embodiments, the liquid crystal layer 30 is composed of negative liquid crystal molecules. In this way, even if the shielding structure 40 on the DPO side is charged, since the shielding structure 40 and the display substrate 20 form a vertical electric field, the vertical electric field only makes the liquid crystal molecules rotate in the plane perpendicular to the vertical electric field, and does not make the liquid crystal molecules tilt in the direction of the electric field, thereby avoiding the light leakage phenomenon in the L0 state and ensuring the display effect.

[0066] It should be noted that the display panel provided in the embodiments of the present application can be provided with other film layers according to actual application needs in addition to the related film layers mentioned above, and the specific setting mode will not be described here.
