DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings in the embodiments of the present application. Based on the embodiments of the present application, any modifications made by those skilled in the art without creative work shall fall within the scope of protection of the present application.

[0043] Please refer to Figures 1 to 3 .like Figure 1 As shown, the display panel 100 provided in the first embodiment of the present application has a curved portion U and a flat portion, and the curved portion U has a curved side L.

[0044] The display panel 100 includes an array substrate 110, an opposite substrate 130 disposed opposite to the array substrate 110, and a liquid crystal layer 120 disposed between the array substrate 110 and the opposite substrate 130. Figure 2 The film layer stacking structure of the planar portion of the display panel 100 is similar to the film layer stacking structure of the curved portion U.

[0045] Specifically, the array substrate 110 includes a first substrate 111, a pixel electrode 112, a common electrode 113 and a plurality of first electrodes 114. The first substrate 111 includes a base and an array layer (not shown) provided on the base. The pixel electrode 112 is provided on the side of the first substrate 111 facing the opposite substrate 130. The common electrode 113 is provided on the side of the pixel electrode 112 away from the first substrate 111 and is insulated from the pixel electrode 112. The common electrode 113 includes a plurality of sub-electrodes E, a first electrode 114 is provided on the side of the sub-electrode E away from the first substrate 111, and the first electrode 114 is insulated from the sub-electrode E. Optionally, an insulating layer is provided between the pixel electrode 112 and the common electrode 113 for insulation, and an insulating layer is provided between the sub-electrode E and the first electrode 114 for insulation (not shown). The opposite substrate 130 includes a second substrate 131 and a plurality of second electrodes 132. A plurality of second electrodes 132 are disposed on a side of the second substrate 131 facing the array substrate 110 , and the extension direction of the second electrodes 132 intersects the curved edge L. In the direction of the curvature radius R of the curved portion U, a first electrode 114 overlaps with a second electrode 132 .

[0046] It should be noted that the long side of the display panel 100 is curved, and thus includes the curved side L. Because the long side of the display panel 100 includes the curved side L, when the display panel 100 is bent to form a curved portion U, film layer misalignment occurs within the curved portion U along the curved side L, squeezing the liquid crystals due to the bend. The second electrode 132 extends in a direction that intersects the curved side L, thereby pulling the squeezed liquid crystals and improving the problem of liquid crystal misalignment. In this first embodiment, the second electrode 132 extends in a direction perpendicular to the curved side L and parallel to the wide side of the display panel 100.

[0047] Optionally, in some other embodiments, the wide side of the display panel 100 is curved, and the wide side of the display panel 100 includes a curved side L. Optionally, the display panel 100 may also include one or more curved portions U, such as 1, 2, 3 or 4.

[0048] The display panel 100 provided in the embodiment of the present application has a curved portion U, with a first electrode 114 provided on the array substrate 110 side and a second electrode 132 provided on the opposite substrate 130 side, with the first electrode 114 and the second electrode 132 corresponding one to one. In the direction of the curvature radius R of the curved portion U, a first electrode 114 overlaps with a second electrode 132, and the extension direction of the second electrode 132 intersects with the curved edge L of the curved portion U. The present application provides an additional electric field to the liquid crystal layer 120 at the curved portion U by adding the first electrode 114 and the second electrode 132, thereby pulling the liquid crystal arrangement, compensating for color deviation in the bright state, and improving the light leakage problem caused by the disordered liquid crystal arrangement in the dark state. The display panel 100 provided in the embodiment of the present application does not require an additional increase in the width of the light shielding layer 133, thereby reducing the transmittance loss caused by the widening of the light shielding layer 133.

[0049] In some related technologies, a compensation layer is added to the display panel to compensate for light emitted due to insufficient deflection of the liquid crystal in the liquid crystal layer or excessive deflection of the liquid crystal, thereby improving light leakage and color shift. However, the method of adding a compensation layer increases the cost of the display panel. In some related technologies, the liquid crystal is compensated by adding a reflective liquid crystal layer in the display panel. However, the process of this compensation method is complex and the reliability of the liquid crystal is not good. The present application sets a first electrode 114 and a second electrode 132 in the display panel 100 to apply an electric field force to the liquid crystal for traction, without the need for an additional compensation layer, saving product costs, and not affecting the reliability of the display panel 100.

[0050] In the display panel 100 of the embodiment of the present application, the color resist layer 134 can be fabricated on the array substrate 110 side (ie, the display panel 100 adopts the COA technology, ie, Color-filter On Array technology), or on the opposite substrate 130 side.

[0051] In the first embodiment, the color resist layer 134 is formed on the opposite substrate 130 side, that is, the opposite substrate 130 is a color filter substrate. The opposite substrate 130 includes a color resist layer 134 and a light shielding layer 133. The color resist layer 134 includes a plurality of color resist blocks. The light shielding layer 133 is disposed on the side of the second substrate 131 facing the array substrate 110. The light shielding layer 133 is provided with a plurality of openings K, the openings K exposing the pixel electrodes 112, and the color resist blocks are disposed in the openings K of the light shielding layer 133, as shown in FIG. Figure 2 shown.

[0052] Specifically, the light shielding layer 133 includes a plurality of second electrodes 132 and a plurality of first light shielding portions BM1. The plurality of first light shielding portions BM1 and the plurality of second electrodes 132 intersect to form a plurality of openings K, as shown in FIG. Figure 3 shown.

[0053] In the first embodiment, the second electrode 132 is made of a low-reflective conductive material, so that the second electrode 132 can block light while also conducting electricity. In other words, the second electrode 132 is reused as part of the light-shielding layer 133, thereby saving the preparation of part of the light-shielding layer 133 and simplifying the film structure of the display panel 100. Optionally, the second electrode 132 can be a single-layer molybdenum (Mo) metal layer, a tungsten (W) metal layer, or a stacked structure of molybdenum and tungsten, or a molybdenum oxide (MoO) layer, or a stacked structure of molybdenum oxide, molybdenum, or tungsten.

[0054] Optionally, the width of the first electrode 114 is smaller than the width of the second electrode 132, such as Figure 2 In the first embodiment, the light shielding layer 133 includes a second electrode 132. The width of the second electrode 132 is greater than the width of the first electrode 114. Thus, the second electrode 132 can block light transmission caused by excessive deflection of liquid crystals under the action of the electric field of the first electrode 114 and the second electrode 132, thereby preventing light leakage caused by insufficient shielding.

[0055] The width of the first electrode 114 is smaller than the width of the sub-electrode E. Since the first electrode 114 is disposed on a side of the sub-electrode E of the common electrode 113 away from the first substrate 111 , the width of the first electrode 114 is smaller than the width of the sub-electrode E, thereby reducing interference of the first electrode 114 on the electric field between the sub-electrode E and the pixel electrode 112 .

[0056] In this first embodiment, please refer to Figure 4 The voltage connected to the first electrode 114 is not equal to the voltage connected to the corresponding second electrode 132, so that an electric field is formed between the first electrode 114 and the second electrode 132, and the liquid crystal in the electric field is corrected or further deflected under the action of the electric field force.

[0057] It should be noted that in this application, the first electrodes 114 correspond to the second electrodes 132 in a one-to-one manner. This one-to-one correspondence means that the overlapping first electrodes 114 and second electrodes 132 correspond to each other in the direction of the curvature radius R of the curved portion U. The voltage applied to the first electrode 114 is not equal to the voltage applied to the corresponding second electrode 132, which means that the voltages applied to the overlapping first electrodes 114 and second electrodes 132 in the direction of the curvature radius R of the curved portion U are not equal.

[0058] In this application, the difference between the voltage connected to the first electrode 114 and the voltage connected to the corresponding second electrode 132 is less than the driving voltage V of the liquid crystal in the display panel 100. op , thereby preventing the first electrode 114 and the second electrode 132 from mistakenly driving the liquid crystal to deflect when a voltage is applied, and a large voltage difference between the first electrode 114 and the second electrode 132 may easily drive the liquid crystal to deflect excessively and fail to play a regulatory role.

[0059] Optionally, the absolute value of the difference between the voltage connected to the first electrode 114 and the voltage connected to the corresponding second electrode 132 is 2-5V, for example, 2V, 2.5V, 3V, 3.5V, 4V, 4.5V or 5V.

[0060] Specifically, the voltage connected to the first electrode 114 is 2V, and the corresponding voltage connected to the second electrode 132 is 0V; the voltage connected to the first electrode 114 is 3V, and the corresponding voltage connected to the second electrode 132 is 0V; the voltage connected to the first electrode 114 is 4V, and the corresponding voltage connected to the second electrode 132 is 0V; the voltage connected to the first electrode 114 is 5V, and the corresponding voltage connected to the second electrode 132 is 0V; the voltage connected to the first electrode 114 is 0V, and the corresponding voltage connected to the second electrode 132 is 2V; the voltage connected to the first electrode 114 is 0V, and the corresponding voltage connected to the second electrode 132 is 5V; the voltage connected to the first electrode 114 is -2V, and the corresponding voltage connected to the second electrode 132 is 0V; the voltage connected to the first electrode 114 is -5V, and the corresponding voltage connected to the second electrode 132 is 0V; the voltage connected to the first electrode 114 is 0V, and the corresponding voltage connected to the second electrode 132 is -3V, etc.

[0061] like Figure 4 As shown, of two adjacent first electrodes 114 located in the curved portion U, the voltage applied to one first electrode 114 is greater than the voltage applied to the second electrode 132 corresponding to the first electrode 114, and the voltage applied to the other first electrode 114 is less than the voltage applied to the second electrode 132 corresponding to the other first electrode 114. In other words, along the direction of the curved edge L, the multiple data driver chips outside the display panel 100 alternately supply power to the first electrode 114, the second electrode 132, the first electrode 114, the second electrode 132, and so on. Specifically, along the direction of the curved edge L, in the first electrode 114 and the second electrode 132 corresponding to the first group, the voltage connected to the first electrode 114 is 5V, and the voltage connected to the second electrode 132 is 0V; in the first electrode 114 and the second electrode 132 corresponding to the second group, the voltage connected to the first electrode 114 is 0V, and the voltage connected to the second electrode 132 is 5V, so that the liquid crystal located in the electric field of the first group of electrodes and the second group of electrodes is subjected to an electric field force deflected in a clockwise direction (based on the paper), and the electric field force pulls the liquid crystal, so that the liquid crystal that is excessively deflected counterclockwise due to the bending rotates back to the clockwise direction, thereby alleviating the light leakage problem caused by excessive stress deflection of the liquid crystal.

[0062] Please refer again Figure 1 .like Figure 1As shown, the curved portion U includes a first sub-portion D1 and a second sub-portion D2. Due to the influence of the curvature, the thickness of the display panel 100 changes. The distance d1 between the first substrate 111 and the second substrate 131 in the first sub-portion D1 is smaller than the distance d2 between the first substrate 111 and the second substrate 131 in the second sub-portion D2. As a result, the liquid crystal in the first sub-portion D1 is squeezed, resulting in a reduced amount of liquid crystal and / or excessive liquid crystal deflection. The absolute value of the difference between the voltage applied to the first electrode 114 in the first sub-portion D1 and the voltage applied to the corresponding second electrode 132 is greater than the absolute value of the difference between the voltage applied to the first electrode 114 and the voltage applied to the corresponding second electrode 132 in the second sub-portion D2. By setting a gradient voltage difference between the first electrode 114 and the corresponding second electrode 132 in the first sub-section D1 and the second sub-section D2, the rotational electric field force applied to the liquid crystal in the first sub-section D1 is stronger, thereby correcting excessive deflection of the liquid crystal, while the rotational electric field force applied to the liquid crystal in the second sub-section D2 is smaller, thereby correspondingly improving the light leakage problem in the first sub-section D1 and the second sub-section D2.

[0063] For example, in the first sub-section D1, the voltage connected to the first electrode 114 is 5V, and the corresponding voltage connected to the second electrode 132 is 0V, or the voltage connected to the first electrode 114 is 0V, and the corresponding voltage connected to the second electrode 132 is 5V; in the second sub-section D2, the voltage connected to the first electrode 114 is 2V, and the corresponding voltage connected to the second electrode 132 is 0V, or the voltage connected to the first electrode 114 is 0V, and the corresponding voltage connected to the second electrode 132 is 2V, etc.

[0064] In the first embodiment, the second sub-portion D2 is located on a side of the first sub-portion D1 that is away from the top T of the curved portion U. That is, the first sub-portion D1 is close to the top T of the curved portion U, while the second sub-portion D2 is away from the top T of the curved portion U. Due to the influence of the curvature radius R, when the display panel 100 is bent at different curvatures, the thickness at the top T and the edge of the curved portion U are different. Optionally, the thickness at the top T of the curved portion U is smaller than the thickness at the edge, or the thickness at the edge of the curved portion U is smaller than the thickness at the top T. In this first embodiment, the thickness at the top T of the curved portion U is smaller than the thickness at the edge. As a result, the distance d1 between the first substrate 111 and the second substrate 131 in the first sub-portion D1 close to the top T of the curved portion U is smaller than the distance d2 between the first substrate 111 and the second substrate 131 in the second sub-portion D2 away from the top T of the curved portion U. In some other embodiments, the thickness at the top T of the curved portion U is greater than the thickness at the edge, so that the distance d2 between the first substrate 111 and the second substrate 131 in the second sub-portion D2 close to the top T of the curved portion U is greater than the distance d1 between the first substrate 111 and the second substrate 131 in the first sub-portion D1 away from the top T of the curved portion U.

[0065] Please refer to Figure 5and Figure 6 , a curvature of 5000R refers to the degree of curvature of a circle with a radius of 5000 millimeters (mm), or 5 meters (m), i.e., a curvature radius R of 5m. Similarly, a curvature of 2000R refers to the degree of curvature of a circle with a radius of 2m. Obviously, the light leakage effect of the display panel 100 provided by the embodiment of the present application is significantly improved.

[0066] Please refer to Figure 7 and Figure 8 The structure of the second embodiment is substantially the same as that of the first embodiment. The differences between the second embodiment and the first embodiment are: the structures of the second electrode 132 and the light shielding layer 133 are different, and the relative positions of the first sub-portion D1 and the second sub-portion D2 are different.

[0067] Specifically, in this second embodiment, the light shielding layer 133 includes a plurality of first light shielding portions BM1 and a plurality of second light shielding portions BM2. The second electrode 132 is disposed on a side of the second light shielding portions BM2 away from the second substrate 131. The plurality of first light shielding portions BM1 and the plurality of second light shielding portions BM2 form a plurality of openings K. The extension direction of the second light shielding portions BM2 is consistent with the extension direction of the second electrode 132, both of which intersect with the curved edge L. When viewed along the curvature radius R of the curved portion U, the pattern of the second electrode 132 is located within the pattern of the second light shielding portions BM2. The extension direction of the first light shielding portions BM1 intersects with the extension direction of the second light shielding portions BM2, thereby forming a plurality of openings K.

[0068] By disposing the second electrode 132 on the side of the second light shielding portion BM2 away from the second substrate 131 , an electric field is formed between the first electrode 114 and the second electrode 132 , thereby pulling the liquid crystal alignment.

[0069] Optionally, the second electrode 132 is made of a conductive material, such as a metal layer of copper (Cu), aluminum (Al), molybdenum, tungsten, or a stack thereof, or other conductive materials.

[0070] In the second embodiment, the first sub-portion D1 is located on the side of the second sub-portion D2 away from the top T of the curved portion U. Specifically, the second sub-portion D2 is close to the top T of the curved portion U, while the first sub-portion D1 is away from the top T of the curved portion U. Specifically, the thickness at the top T of the curved portion U is greater than the thickness at the edge. As a result, the distance d2 between the first substrate 111 and the second substrate 131 in the second sub-portion D2 near the top T of the curved portion U is greater than the distance d1 between the first substrate 111 and the second substrate 131 in the first sub-portion D1 away from the top T of the curved portion U. As a result, the liquid crystal within the first sub-portion D1 is squeezed, resulting in a reduced amount of liquid crystal and / or excessive liquid crystal deflection. The absolute value of the difference between the voltage applied to the first electrode 114 in the first sub-portion D1 and the voltage applied to the corresponding second electrode 132 is greater than the absolute value of the difference between the voltage applied to the first electrode 114 and the voltage applied to the corresponding second electrode 132 in the second sub-portion D2. By setting a gradient voltage difference between the first electrode 114 and the corresponding second electrode 132 in the first sub-section D1 and the second sub-section D2, the rotational electric field force applied to the liquid crystal in the first sub-section D1 is stronger, thereby correcting excessive deflection of the liquid crystal, while the rotational electric field force applied to the liquid crystal in the second sub-section D2 is smaller, thereby correspondingly improving the light leakage problem in the first sub-section D1 and the second sub-section D2.

[0071] Please refer to Figure 9 The display device 1000 includes a plurality of data driver chips C and the display panel 100 described above. The data driver chip C is electrically connected to the first electrode 114 and the second electrode 132. It is understood that when the first electrode 114 is connected to the common electrode 113 in a line to obtain the common electrode 113 potential, the second electrode 132 is electrically connected to the data driver chip C to obtain a potential that is not equal to the common electrode 113 potential. Alternatively, the second electrode 132 is connected to the common electrode 113 in a line to obtain the common electrode 113 potential, and the first electrode 114 is electrically connected to the data driver chip C to obtain a potential that is not equal to the common electrode 113 potential. The data driver chip C provides voltage to the first electrode 114 or the second electrode 132. When multiple gradient potentials are set between the first electrode 114 and the second electrode 132, the number of data driver chips C increases accordingly.
