[0026] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0027] Figure 1 This is a schematic diagram of the structure of a display panel in the prior art. Figure 1 As shown, the display panel 10' includes a display area 100' and a non-display area 200', and the display area 100' surrounds at least a portion of the non-display area 200'. Further, the display area 100' includes a first display area 100A' and a second display area 100B', and the second display area 100B' is located on a side of the non-display area 200' away from the first display area 100A'. At the same time, the display panel 10' includes an array substrate and a liquid crystal layer, and the liquid crystal layer includes liquid crystal. Specifically, the injection position of the liquid crystal is located on one side of the first display area 100A', that is, compared with the first display area 100A', the liquid crystal flow rate of the second display area 100B' is low, that is, the liquid crystal content at the second display area 100B' is low, and bubbles are likely to exist in the second display area 100B', affecting the overall display effect of the display panel 10'.

[0028] Based on the above technical problems, an embodiment of the present invention provides a display panel, which includes a first substrate and a second substrate arranged in opposite directions, and a liquid crystal layer arranged between the first substrate and the second substrate; the display panel also includes a display area and at least one non-display area, the display area surrounding at least a portion of the non-display area; the display area includes a first display area and a second display area, the display panel also includes a first liquid crystal drop-in position, the first liquid crystal drop-in position is located in the setting area of the first display area, and at least a portion of the second display area is located on a side of the non-display area away from the first liquid crystal drop-in position; the display panel also includes a liquid crystal guide wall arranged between the first substrate and the second substrate, the liquid crystal guide wall being used to guide the liquid crystal in the liquid crystal layer to flow into the second display area. Using the above technical solution, by setting the liquid crystal guide wall, the flow direction of the liquid crystal in the liquid crystal layer is guided, that is, the liquid crystal is guided to flow into the second display area, while preventing the outflow of liquid crystal from the second display area and the occurrence of bubbles, thereby ensuring the overall display effect of the display panel.

[0029] Figure 2 is a structural diagram of a display panel provided by an embodiment of the present invention, Figure 3 Figure 2 A schematic cross-sectional view of a display panel along the section line AA', referring to Figure 2 and Figure 3 As shown, the display panel 10 provided by the embodiment of the present invention includes a first substrate 110 and a second substrate 120 arranged relatively to each other, and a liquid crystal layer 130 arranged between the first substrate 110 and the second substrate 120; the display panel 10 also includes a display area 100 and at least one non-display area 200, and the display area 100 surrounds at least part of the non-display area 200; the display area 100 includes a first display area 100A and a second display area 100B, and the display panel 10 also includes a first liquid crystal dropping position 131, the first liquid crystal dropping position 131 is located in the setting area of the first display area 100A, and at least part of the second display area 100B is located on the side of the non-display area 200 away from the first liquid crystal dropping position 131; the display panel 10 also includes a liquid crystal guide wall 300 arranged between the first substrate 110 and the second substrate 120, and the liquid crystal guide wall 300 is used to guide the liquid crystal in the liquid crystal layer 130 to flow into the second display area 100B.

[0030] Exemplarily, the display panel 10 includes a display area 100 and a non-display area 200. Devices such as a camera, an earpiece, or a sensor can be set in the non-display area 200 to ensure the corresponding functions of the display panel; the display function of the display area 100 is used to ensure the display effect of the display panel 10. Furthermore, the display area 100 surrounds at least part of the non-display area 200, that is, at least one non-display area 200 is set in the display area 100, so as to ensure the display effect of full-screen display. It should be noted that the non-display area 200 can be located at any position in the display area 100, and the display area 100 can include one or more non-display areas 200. Figure 2 The following description will be made by taking as an example that the non-display area 200 is located in the upper middle of the display area 100 and one non-display area 200 is provided in the display area 100 .

[0031] Among them, reference Figure 3 As shown, the display panel 10 includes a first substrate 110 and a second substrate 120, and the first substrate 110 and the second substrate 120 are arranged relative to each other, and a liquid crystal layer 130 is arranged in the first substrate 110 and the second substrate 120. Specifically, the first substrate 110 includes a driving circuit 111, and the driving circuit 111 is electrically connected to the pixel electrode 112. The display panel 10 also includes a common electrode (not shown in the figure), which can be arranged in the first substrate 110 or in the second substrate 120. The embodiment of the present invention does not specifically limit this. By electrically connecting the driving circuit 111 to the pixel electrode 112, an electric field is generated between the pixel electrode 112 and the common electrode, driving the liquid crystal in the liquid crystal layer 130 to deflect, ensuring that the light entering the display panel 10 is emitted through the liquid crystal layer 130, thereby achieving the display effect of the display panel 10. Among them, the driving circuit 111 includes a thin film transistor, and the thin film transistor includes an active layer, a source, a gate and a drain, etc. At the same time, the first substrate 110 also includes a stacked substrate, a buffer layer, an insulating layer, a planarization layer and an alignment layer, etc. The specific film layer setting method can be adaptively adjusted by technical personnel in this field according to actual needs, and the present invention does not make specific limitations on this.

[0032] Furthermore, the display area 100 of the display panel 10 includes a first display area 100A and a second display area 100B. The first display area 100A and the second display area 100B both include the first substrate 110, the second substrate 120, and the liquid crystal layer 130. The liquid crystal is injected into the liquid crystal layer 130 through the first liquid crystal droplet position 131 in the display panel 10, ensuring that the liquid crystal layer 130 contains liquid crystal. Figure 2As shown, the first display area 100A includes the first liquid crystal dropping position 131, and the second display area 100B is located on the side of the non-display area 200 away from the first liquid crystal dropping position 131, that is, the second display area 100B is farther away from the first liquid crystal dropping position 131 than the first display area 100A. It should be noted that the specific position of the first liquid crystal dropping position 131 is not fixed. Figure 2 The above positions are used as examples only. Because the second display area 100B is relatively far from the first liquid crystal droplet location 131, the liquid crystal content in the liquid crystal layer 130 in the second display area 100B is relatively low. As a result, bubbles are easily formed in the second display area 100B, affecting the display quality of the second display area 100B and, in turn, the display quality of the display panel 10.

[0033] Furthermore, the display panel 10 further includes a liquid crystal guide wall 300, referring to Figure 2 and Figure 3 As shown, the liquid crystal guide wall 300 is disposed between the first substrate 110 and the second substrate 120, which can block the flow of liquid crystal on both sides of the liquid crystal guide wall 300, and the liquid crystal guide wall 300 also has the effect of guiding the flow direction of the liquid crystal in the liquid crystal layer 130. Figure 2 As shown, the provision of the liquid crystal guide walls 300 can prevent the liquid crystal in the liquid crystal layer 130 in the second display area 100B from flowing out of the second display area 100B, thereby preventing the loss of liquid crystal in the liquid crystal layer 130 in the second display area 100B. Furthermore, the liquid crystal guide walls 300 can guide the liquid crystal in the liquid crystal layer 130 back to the second display area 100B, thereby preventing the formation of bubbles in the second display area 100B. This improves the display quality of the second display area 100B and the overall display quality of the display panel 10.

[0034] In summary, the display panel provided by the embodiment of the present invention, by setting a liquid crystal guide wall in the display panel, the liquid crystal guide wall is used to guide the liquid crystal in the liquid crystal layer to flow into the second display area, to prevent the liquid crystal flowing into the second display area from flowing out, resulting in a low liquid crystal content in the second display area and the appearance of bubbles, etc., thereby ensuring the display effect of the second display area, and further ensuring the display effect of the entire display panel.

[0035] Continue to refer Figure 2 As shown, the liquid crystal guide wall 300 includes at least one semi-enclosed guide wall 310; the semi-enclosed guide wall 310 includes a semi-enclosed guide wall body 310A and a guide opening 310B, and the guide opening 310B is located on the side of the semi-enclosed guide wall body 310A close to the second display area 100B.

[0036] Specifically, the liquid crystal diversion barrier 300 includes a semi-enclosed diversion barrier 310, which includes a semi-enclosed barrier body 310A and a diversion opening 310B. The semi-enclosed barrier body 310 prevents liquid crystal in the liquid crystal layer from flowing between its two sides, that is, preventing liquid crystal in the second display area 100B from flowing into the first display area 100A, which would reduce the liquid crystal content in the second display area 100B and cause bubbles. The diversion opening 310B can guide the direction of liquid crystal flow, that is, the opening direction of the diversion opening 310B determines the direction of liquid crystal flow. The diversion opening 310B is located on the side of the semi-enclosed retaining wall body 310A close to the second display area 100B, that is, by setting the semi-enclosed retaining wall body 310A, the loss of liquid crystal in the second display area 100B can be avoided, and by setting the diversion opening 310B, the liquid crystal in the liquid crystal layer can be guided to flow into the second display area 100B, that is, the bubble phenomenon caused by insufficient liquid crystal content in the liquid crystal layer in the second display area 100B is solved, thereby ensuring the display effect of the second display area 100B, thereby ensuring the overall display effect of the display panel 10. Figure 4 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Figure 5 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Figure 6 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figures 4 to 6 As shown, the liquid crystal guide wall 300 includes at least two semi-enclosed guide walls 310; along the long axis direction X of the non-display area 200, there are two semi-enclosed guide walls 310 located on both sides of the center of the second display area 100B.

[0037] The liquid crystal guide walls 300 include at least two semi-enclosed guide walls 310, one located on either side of the center of the second display area 100B. The two semi-enclosed guide walls 310 effectively prevent the loss of liquid crystal in the second display area 100B and further ensure that the liquid crystal in the liquid crystal layer flows into the second display area 100B. This effectively resolves the problem of bubbles in the second display area 100B caused by insufficient liquid crystal content in the liquid crystal layer, ensuring the display quality of the second display area 100B and, therefore, the overall display quality of the display panel 10.

[0038] For further reference, Figures 4 to 6 As shown, the semi-enclosed retaining wall body 310A in the semi-enclosed diversion retaining wall 310 can have various forms, such as a polygonal shape surrounding the diversion opening 310B, an arc shape surrounding the diversion opening 310B, etc. The embodiment of the present invention does not specifically limit the shape of the semi-enclosed diversion retaining wall 310.

[0039] Figure 7 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Figure 7 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 7 and Figure 8 As shown, the liquid crystal guide wall 300 includes a fully enclosed guide wall 320; at least part of the fully enclosed guide wall 320 is set in the second display area 100B; the display panel 10 also includes a second liquid crystal dropping position 132, and the second liquid crystal dropping position 132 is located in the setting area of the fully enclosed guide wall 320.

[0040] Furthermore, the liquid crystal guide baffle 300 further includes a fully enclosed guide baffle 320, which can block the flow of liquid crystal on both sides thereof, more effectively preventing the liquid crystal in the second display area 100B from flowing out, and preventing bubbles from appearing in the second display area 100B. Figure 7 and Figure 8 As shown, the shape of the fully enclosed diversion retaining wall 320 can be various forms, and the embodiment of the present invention does not specifically limit the shape of the fully enclosed diversion retaining wall 320.

[0041] Furthermore, the display panel 10 also includes a second liquid crystal dropping position 132, and the second liquid crystal dropping position 132 is arranged in the setting area of the fully enclosed guide baffle 320. While ensuring that the liquid crystal in the fully enclosed guide baffle 320 will not flow out, by increasing the second liquid crystal second position 132, it can be ensured that there will be no bubbles in the liquid crystal content in the fully enclosed guide baffle 320, that is, it is ensured that there will be no bubbles in the second display area 100B, thereby improving the display effect of the second display area 100B and improving the overall display effect of the display panel 10.

[0042] Continue to refer Figure 7 As shown, along the extension direction Y of the short axis of the non-display area 200 , the fully enclosed guide wall 320 at least overlaps with the center of the non-display area 200 .

[0043] Specifically, the second display area 100B is located on a side of the non-display area 200 away from the first liquid crystal instillation position 131. That is, the second display area 200 has a low liquid crystal content at the intersection with the non-display area 200, and the second display area 200 has an even lower liquid crystal content at the intersection with the center of the non-display area 200. Therefore, bubbles are more likely to form in the area corresponding to the center of the second display area 100B and the non-display area 200. Furthermore, by having the fully enclosed guide wall 320 overlap at least with the center of the non-display area 200, bubbles can be avoided within the fully enclosed guide wall 320, that is, bubbles can be avoided in the area corresponding to the center of the second display area 100B and the non-display area 200, thereby ensuring the display quality of the second display area 100B and, therefore, the overall display quality of the display panel 10.

[0044] Figure 9 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. Figure 10 is a schematic diagram of the structure of another display panel provided by an embodiment of the present invention, referring to Figure 7 、 Figure 9 and Figure 10 As shown, along the long axis direction X of the non-display area 200, the extension length L2 of the fully enclosed diversion retaining wall 320 is less than the extension length L of the non-display area 200; or, along the long axis direction X of the non-display area 200, the extension length L1 of the fully enclosed diversion retaining wall 320 is equal to the extension length L of the non-display area 200; or, along the long axis direction X of the non-display area 200, the extension length L3 of the fully enclosed diversion retaining wall 300 is greater than the extension length L of the non-display area 200.

[0045] For example, the fully enclosed diversion retaining wall 320 is a rectangle. Figure 7 As shown, the extension length L1 of the fully enclosed diversion retaining wall 320 is equal to the extension length L of the non-display area 200, for example, L1 and L are both 52 mm. Figure 9 As shown, the extension length L2 of the fully enclosed guide wall 320 is less than the extension length L of the non-display area 200, for example, L is 52 mm and L2 is 4 mm, and the center of the fully enclosed guide wall 320 overlaps with the center of the non-display area 200. Figure 10 As shown, the extended length L3 of the fully enclosed flow-guiding baffle 300 is greater than the extended length L of the non-display area 200. For example, L is 52 mm and L3 is 82 mm. Furthermore, the center of the fully enclosed flow-guiding baffle 320 overlaps with the center of the non-display area 200. In other words, the extended length of the fully enclosed flow-guiding baffle 320 can be adaptively adjusted to ensure that the fully enclosed flow-guiding baffle 320 overlaps with the center a1 of the non-display area 200. This allows the extended length of the fully enclosed flow-guiding baffle 320 to be adjusted to prevent bubbles from forming in the second display area 100B. The embodiments of the present invention do not limit the extended length or specific value of the fully enclosed flow-guiding baffle 320.

[0046] Figure 11 yes Figure 4 An enlarged schematic diagram of the D area in the middle, Figure 12 yes Figure 7 An enlarged schematic diagram of the E region in the middle, Figure 13 yes Figure 11 Another cross-sectional diagram of a display panel along the section line CC' is shown in FIG. Figures 11 to 13 As shown, the non-display area 200 includes a hole area 210 and a frame glue area 220. The frame glue area 210 is provided with frame glue, and the frame glue surrounds the hole area 210. The liquid crystal guide retaining wall 300 includes a first retaining wall section 330, and the first retaining wall section 330 is provided between the liquid crystal and the frame glue.

[0047] The non-display area 200 includes a hole-punch area 210 and a glue frame area 220. Devices such as a camera, an earpiece, or a sensor can be installed in the hole-punch area 210 to enrich the functionality of the display panel 10. Furthermore, a glue frame area 210 is provided around the hole-punch area 210. That is, the glue frame in the glue frame area 210 surrounds the hole-punch area 210 to protect the shape of the hole-punch area 210 and the devices installed therein, etc. This embodiment of the present invention does not specifically limit this.

[0048] Furthermore, the liquid crystal guide wall 300 includes a first wall section 330, such as Figures 11 to 13 As shown, whether the semi-enclosed diversion retaining wall 310 or the fully enclosed diversion retaining wall 320 is provided, the first retaining wall section 330 is disposed between the liquid crystal and the sealant to prevent contact between the sealant frame and the liquid crystal. If the sealant frame and the liquid crystal come into contact, the liquid crystal could penetrate the sealant frame, shortening the service life of the display panel 10. By providing the first retaining wall section 330, the impact force exerted by the liquid crystal on the sealant area 210 can be eliminated or reduced, eliminating or reducing the risk of the liquid crystal penetrating the sealant in the sealant area 210, thereby ensuring normal display of the display panel 10.

[0049] Continue to refer Figures 11 to 13 As shown, the first retaining wall section 330 is disposed in the non-display area 200 .

[0050] Specifically, the light of the display panel 10 cannot pass through the first blocking wall section 330 , so the first blocking wall section 330 is disposed in the non-display area 200 , that is, the location of the first blocking wall section 330 does not affect the display effect of the display panel 10 .

[0051] Figure 14 yes Figure 11 Another cross-sectional diagram of a display panel along the section line BB', continue to refer to Figures 11 to 14 As shown, the display panel 10 also includes a shading structure 121 located on one side of the second substrate 120; the liquid crystal guide retaining wall 300 also includes a second retaining wall section 340, which is connected to the first retaining wall section 330; along the thickness direction h of the display panel 10, the shading structure 121 covers the second retaining wall section 340.

[0052] Specifically, the second substrate 120 of the display panel 10 is a color filter substrate, which includes a light-shielding structure 121 and multiple color-resistance blocks. The color-resistance blocks include a red color-resistance block 121R, a green color-resistance block 121G, and a blue color-resistance block 121B. Light emitted by the display panel 10 passes through the color-resistance blocks of different colors and presents different colors, ensuring color display on the display panel 10. Furthermore, the light-shielding structure 121 can block the transmission of light, thereby preventing crosstalk between lights of different colors and ensuring the overall display quality of the display panel 10.

[0053] Furthermore, the liquid crystal guide retaining wall 300 also includes a second retaining wall section 340. By connecting the first retaining wall section 330 with the second retaining wall section 340, the liquid crystal in the second display area 100B is prevented from escaping and the liquid crystal in the liquid crystal layer 130 is guided to flow into the second display area 100B. However, the locations where the first retaining wall section 330 and the second retaining wall section 340 are located are not light-transmissive, meaning that the display panel 10 does not display at the locations where the first retaining wall section 330 and the second retaining wall section 340 are located. Therefore, the second retaining wall section 340 overlaps with the light-shielding structure 121 in the thickness direction h of the display panel 10. This means that the location of the second retaining wall section 340 does not affect the display effect of the display panel 10.

[0054] Continue to refer Figure 14 As shown, the display panel 10 further includes a support column 140 located in the display area 100 and between the first substrate 110 and the second substrate 120 ; the liquid crystal guide wall 300 is disposed on the same layer as the support column 140 .

[0055] Specifically, refer to Figure 14 As shown, the display panel 10 also includes support columns 140. Support columns 1401 serve to support the entire display panel 10. Support columns 140 are located between the first substrate 110 and the second substrate 120, providing space for liquid crystal flow. Furthermore, liquid crystal guide walls 300 can be co-located with support columns 140, facilitating a thinner design for the display panel 10. This also allows support columns 140 and liquid crystal guide walls 300 to be fabricated together, simplifying the fabrication process for the liquid crystal guide walls 300 and improving overall fabrication efficiency for the display panel 10.

[0056] Continue to refer Figure 14 As shown, the support column 140 includes a main support column 141 and an auxiliary support column 142. Along the thickness direction h of the display panel 10, the height h1 of the main support column 141 is greater than the height h2 of the auxiliary support column 142; along the thickness direction h of the display panel 10, the height h3 of the liquid crystal guide wall 300 is the same as the height h2 of the auxiliary support column 142.

[0057] Specifically, the support column 140 includes a main support column 141 and an auxiliary support column 142. Figure 14As shown, the main support columns 141 provide support for the display panel 10, while the auxiliary support columns 142 ensure a certain amount of space for pressing against the display panel 10. Therefore, the height h1 of the main support columns 141 is greater than the height h2 of the auxiliary support columns 142. The height h3 of the liquid crystal guide walls 300 is the same as the height h2 of the auxiliary support columns 142, meaning that the height h3 of the liquid crystal guide walls 300 is less than the height h1 of the main support columns 141. If the height h3 of the liquid crystal guide walls 300 were the same as the height h1 of the main support columns 141, the second display area 100B would be taller than the first display area 100A, resulting in different optical path lengths between the first and second display areas 100A, 100B, and different display effects between the two areas. By setting the height h3 of the liquid crystal guide walls 300 to be the same as the height h2 of the auxiliary support columns 142, the optical path lengths between the first and second display areas 100A, 100B, are kept the same, ensuring uniform display across the entire display area 100.

[0058] refer to Figures 2 to 14 As shown, the liquid crystal guide structure 300 includes a continuous guide structure.

[0059] Specifically, whether the liquid crystal guide structure 300 is a semi-enclosed guide wall 310 or a fully enclosed guide wall 320, both are continuous guide structures, which can ensure the liquid crystal guide structure 300's guide effect on the liquid crystal. If the liquid crystal guide structure 300 is not a continuous guide structure, the guide effect on the liquid crystal will be weakened in the gaps between its discrete structures.

[0060] Continue to refer Figure 6 As shown, the liquid crystal guide barrier 300 includes at least two barrier sections that are interconnected and extend in intersecting directions.

[0061] Specifically, the liquid crystal guide retaining wall 300 includes two connected retaining wall sections, and the extension directions thereof are different, that is, the liquid crystal guide retaining wall 300 is polygonal. The polygonal liquid crystal guide retaining wall 300 can ensure that its opening can guide the liquid crystal in the liquid crystal layer into the second display area 100B. At the same time, the structure of the liquid crystal guide retaining wall 300 is diverse, with Figure 6 For example, the liquid crystal diversion retaining wall 300 includes two retaining wall sections, and the different retaining wall sections extend in different directions, but adjacent retaining wall sections are connected to each other. Furthermore, the liquid crystal diversion retaining wall 300 may include more than two retaining wall sections, for example, the liquid crystal diversion retaining wall 300 may be polygonal in shape, etc. This is not specifically limited in the present embodiment.
