[0024] The embodiments of the present application provide an array substrate, a display panel, and a method for manufacturing the array substrate, which are described in detail below.

[0025] like Figure 1 The figure shows a schematic structural diagram of an embodiment of an array substrate provided in an embodiment of the present application. Figure 1 In the embodiment shown, the array substrate includes a plurality of pixel units, each pixel unit includes a first display area and a second display area, and the array substrate includes:

[0026] substrate 10;

[0027] The first electrode layer 20 does not completely cover the substrate 10 . The first electrode layer 20 includes a first electrode 201 and a second electrode 202 .

By setting capacitors of different capacitance values ​​in different display areas of the array substrate, the present application can control the driving voltage of different display areas, thereby controlling the liquid crystal deflection angle of different display areas, thereby achieving adjustment of images with different viewing angles.

[0031] like Figure 2 FIG. 1 is a structural diagram of another embodiment of the array substrate provided in the embodiment of the present application. Figure 2 In the embodiment shown, the array substrate also includes a first passivation layer 40, which is arranged above the first electrode layer 20, and the first passivation layer 40 completely covers the substrate 10 and the first electrode layer 20; that is, the first passivation layer completely covers the first electrode layer 20, and other areas on the substrate 10 except the first electrode layer 20.

[0032] A third via hole and a fourth via hole are also provided on the first passivation layer 40. The third via hole is located above the first electrode 201 in the first display area, and the fourth via hole is located above the second electrode 202 in the second display area. In other words, the third via hole is located corresponding to the first electrode 201, and the fourth via hole is located corresponding to the second electrode 202.

[0033] The third via hole is the via hole formed on the first passivation layer 40 of the aforementioned first via hole, and the fourth via hole is the via hole formed on the first passivation layer 40 of the second via hole.

[0034] Please refer to Figure 2 ,exist Figure 2 In the embodiment, the array substrate further includes a second passivation layer 50, which is disposed above the first passivation layer 40 and completely covers the first passivation layer 40. A fifth via hole and a sixth via hole are also disposed on the second passivation layer 50. The fifth via hole is located above the third via hole in the first display area, and the sixth via hole is located above the fourth via hole in the second display area. In other words, the third via hole and the fifth via hole are disposed in correspondence with each other, and the fourth via hole and the sixth via hole are disposed in correspondence with each other.

[0035] The fifth via hole is a via hole formed on the second passivation layer 50 by the first via hole, and the sixth via hole is a via hole formed on the second passivation layer 50 by the second via hole.

[0036] It should be noted that the third electrode is located inside the third and fifth vias, as well as in a portion of the area above the second passivation layer 50 near the fifth via; the third electrode completely fills the interiors of the third and fifth vias. The third electrode 301 is connected to the first electrode 201 through the third and fifth vias (i.e., the first via), and the third electrode 301 and the first electrode 201 form a first capacitor in the first display area.

[0037] Please refer to Figure 2 ,exist Figure 2 The middle array substrate further includes a third passivation layer 60, which completely covers the second passivation layer 50 and the third electrode 301. However, a seventh via hole is provided in the third passivation layer 60 above the sixth via hole in the second display area. The seventh via hole is formed on the third passivation layer 60 from the second via hole. In some embodiments, the third passivation layer 60 may be provided only in the second display area.

[0038] At this time, the fourth via hole, the sixth via hole and the seventh via hole constitute a second via hole, and the fourth electrode 302 is arranged inside the fourth via hole, the sixth via hole and the seventh via hole, and a portion of the area above the third passivation layer 60 near the seventh via hole. Figure 2As shown, at this time, the fourth electrode 302 is connected to the second electrode 202 through the fourth via hole, the sixth via hole and the seventh via hole (ie, the second via hole), and the fourth electrode 302 and the second electrode 202 constitute a second capacitor in the second display area.

[0039] At this time, the first display area includes a first capacitor, and the second display area includes a second capacitor; and the capacitance value of the capacitor is inversely proportional to the distance between the two electrodes of the capacitor, so the distance between the two electrodes of the capacitor can be adjusted to adjust the size of the capacitor. For the embodiment of the present application, the size of the capacitance value can be adjusted by adjusting the thickness of the passivation layer; specifically, the thickness of the passivation layer in the first display area is different from the thickness of the passivation layer in the second display area. Among them, the thickness of at least one of the first passivation layer and the second passivation layer in the first display area is different from the thickness in the second display area. Specifically, adjusting the size of the first capacitor can be achieved by adjusting the thickness of the first passivation layer 40 and the second passivation layer 50; and adjusting the size of the second capacitor can be achieved by adjusting the thickness of the first passivation layer 40, the second passivation layer 50 and the third passivation layer 60.

[0040] By adjusting the thickness of the passivation layer, the first and second capacitors are adjusted, and the voltage across the first and second capacitors is adjusted to adjust the liquid crystal deflection angle. The liquid crystal deflection angle affects the image ultimately displayed on the display panel. Therefore, in the embodiment of the present application, two capacitors are provided, and the image on the display panel is adjusted by adjusting the distance between the electrodes of the two capacitors.

[0041] The embodiment of the present application further provides a display panel, which includes the array substrate as described in any one of the above items. Figure 1 The figure shows a schematic structural diagram of an embodiment of an array substrate provided in an embodiment of the present application. Figure 1 In the embodiment shown, the array substrate includes a first display area and a second display area, and the array substrate includes:

[0042] substrate 10;

[0043] The first electrode layer 20 does not completely cover the substrate 10 . The first electrode layer 20 includes a first electrode 201 and a second electrode 202 . The first electrode 201 is located in the first display area, and the second electrode 202 is located in the second display area.

[0044] The second electrode layer 30 is located above the first electrode layer 20. The second electrode layer 30 includes a third electrode 301 and a fourth electrode 302. The third electrode 301 is located in the first display area and connected to the first electrode 201 through a first via hole. The fourth electrode 302 is located in the second display area and connected to the second electrode 202 through a second via hole.

[0045] The first electrode 201 and the third electrode 301 form a first capacitor, and the second electrode 202 and the fourth electrode 302 form a second capacitor. The capacitances of the first capacitor and the second capacitor are different.

[0046] The display panel provided in an embodiment of the present application includes the array substrate as described above, the array substrate including a first display area and a second display area, and further including: a substrate; a first electrode layer, the first electrode layer not completely covering the substrate, the first electrode layer including a first electrode and a second electrode, the first electrode being located in the first display area, and the second electrode being located in the second display area; a second electrode layer, the second electrode layer being located above the first electrode layer, the second electrode layer including a third electrode and a fourth electrode, the third electrode being located in the first display area and electrically connected to the first electrode through a first via hole, and the fourth electrode being located in the second display area and electrically connected to the second electrode through a second via hole; wherein the first electrode and the third electrode form a first capacitor, the second electrode and the fourth electrode form a second capacitor, and the first capacitor and the second capacitor have different capacitances. By setting capacitors of different capacitances in different display areas of the array substrate, the present application can control the driving voltages of different display areas, thereby controlling the liquid crystal deflection angles of different display areas, thereby achieving adjustment of images with different viewing angles.

[0047] like Figure 2 FIG. 1 is a structural diagram of another embodiment of the array substrate provided in the embodiment of the present application. Figure 2 In the embodiment shown, the array substrate also includes a first passivation layer 40, which is arranged above the first electrode layer 20, and the first passivation layer 40 completely covers the substrate 10 and the first electrode layer 20; that is, the first passivation layer completely covers the first electrode layer 20, and other areas on the substrate 10 except the first electrode layer 20.

[0048] A third via hole and a fourth via hole are also provided on the first passivation layer 40. The third via hole is located above the first electrode 201 in the first display area, and the fourth via hole is located above the second electrode 202 in the second display area. In other words, the third via hole is located corresponding to the first electrode 201, and the fourth via hole is located corresponding to the second electrode 202.

[0049] The third via hole is the via hole formed on the first passivation layer 40 of the aforementioned first via hole, and the fourth via hole is the via hole formed on the first passivation layer 40 of the second via hole.

[0050] Please refer to Figure 2 ,exist Figure 2In the embodiment, the array substrate further includes a second passivation layer 50, which is disposed above the first passivation layer 40 and completely covers the first passivation layer 40. A fifth via hole and a sixth via hole are also disposed on the second passivation layer 50. The fifth via hole is located above the third via hole in the first display area, and the sixth via hole is located above the fourth via hole in the second display area. In other words, the third via hole and the fifth via hole are disposed in correspondence with each other, and the fourth via hole and the sixth via hole are disposed in correspondence with each other.

[0051] The fifth via hole is a via hole formed on the second passivation layer 50 by the first via hole, and the sixth via hole is a via hole formed on the second passivation layer 50 by the second via hole.

[0052] It should be noted that the third electrode is located inside the third and fifth vias, as well as in a portion of the area above the second passivation layer 50 near the fifth via; the third electrode completely fills the interiors of the third and fifth vias. The third electrode 301 is connected to the first electrode 201 through the third and fifth vias (i.e., the first via), and the third electrode 301 and the first electrode 201 form a first capacitor in the first display area.

[0053] Please refer to Figure 2 ,exist Figure 2 The middle array substrate further includes a third passivation layer 60, which completely covers the second passivation layer 50 and the third electrode 301. However, a seventh via hole is provided in the third passivation layer 60 above the sixth via hole in the second display area. The seventh via hole is formed on the third passivation layer 60 by the second via hole.

[0054] At this time, the fourth via hole, the sixth via hole and the seventh via hole constitute a second via hole, and the fourth electrode 302 is arranged inside the fourth via hole, the sixth via hole and the seventh via hole, and a portion of the area above the third passivation layer 60 near the seventh via hole. Figure 2 As shown, at this time, the fourth electrode 302 is connected to the second electrode 202 through the fourth via hole, the sixth via hole and the seventh via hole (ie, the second via hole), and the fourth electrode 302 and the second electrode 202 constitute a second capacitor in the second display area.

[0055] In this case, the first display area includes the first capacitor, and the second display area includes the second capacitor. The capacitance of a capacitor is inversely proportional to the distance between its two electrodes, so the distance between the two electrodes can be adjusted to adjust the capacitance. In this embodiment of the present application, the first capacitor can be adjusted by adjusting the thickness of the first passivation layer 40 and the second passivation layer 50. The second capacitor can be adjusted by adjusting the thickness of the first passivation layer 40, the second passivation layer 50, and the third passivation layer 60.

[0056] By adjusting the thickness of the passivation layer, the first and second capacitors are adjusted, and the voltage across the first and second capacitors is adjusted to adjust the liquid crystal deflection angle. The liquid crystal deflection angle affects the image ultimately displayed on the display panel. Therefore, in the embodiment of the present application, two capacitors are provided, and the image on the display panel is adjusted by adjusting the distance between the electrodes of the two capacitors.

[0057] like Figure 3 The figure shows a schematic diagram of the structure of the third electrode prepared in the embodiment of the present application. Figure 3 In the embodiment, a third via hole is provided at a position corresponding to the first electrode 201 on the first passivation layer 40, and a fifth via hole is provided at a position corresponding to the second via hole on the second passivation layer 50. At this time, the material of the third electrode 301 is deposited on the second passivation layer 50 and inside the third and fifth via holes using a method such as chemical vapor deposition (CVD), so that the material of the third electrode 301 completely covers the second passivation layer 50 and inside the third and fifth via holes.

[0058] At this time, the third electrode material completely covering the second passivation layer 50 needs to be etched to remove part of the third electrode material located in the second display area, leaving only part of the third electrode material located in the first display area and close to the fifth via hole to obtain the third electrode 301.

[0059] like Figure 4 The figure shows a schematic diagram of the structure of preparing the third passivation layer provided in the embodiment of the present application. Figure 4 In the embodiment, it is necessary to coat the third passivation layer 60 material on the second passivation layer 50 and the third electrode using a method such as CVD, so that the third passivation layer material completely covers the second passivation layer 50 and the third electrode.

[0060] After coating the third passivation layer, the fourth electrode needs to be prepared. Figure 5 The figure shows a schematic diagram of the structure for preparing the fourth electrode according to an embodiment of the present application. Specifically, the fourth, sixth, and seventh vias are first prepared in the second display area. Specifically, the seventh via is prepared on the third passivation layer, the sixth via is prepared on the second passivation layer, and the fourth via is prepared on the first passivation layer. The fourth, sixth, and seventh vias are positioned correspondingly, ultimately forming a second via that penetrates the first, second, and third passivation layers.

[0061] After the second via hole is prepared, a fourth electrode material is coated on the third passivation layer and inside the second via hole using a CVD method, so that the fourth electrode material completely covers the third passivation layer and the inside of the second via hole. Figure 5 As shown, the uppermost layer is the coated fourth electrode material.

[0062] To obtain the final fourth electrode, the coated fourth electrode material needs to be etched to remove a portion of the fourth electrode material, leaving only a portion of the fourth electrode material near the second via hole (i.e., the seventh via hole) in the second display area. The fourth electrode and the second electrode constitute the second capacitor in the second display area.

[0063] Please refer to Figure 2 , Figure 2 The complete structural diagram of the array substrate provided in the embodiment of the present application. Figure 2 In the embodiment, the third passivation layer completely covers the third electrode, and the fourth electrode is partially disposed above the third passivation layer.

[0064] It should be noted that in the embodiments of the present application, the capacitance of the first capacitor and the second capacitor is adjusted mainly by adjusting the thickness of the passivation layer; however, in other embodiments, this can also be achieved by adjusting the electrode area in the capacitor, specifically by adjusting the area of ​​the first electrode 201, the second electrode 202, the third electrode 301 and the fourth electrode 302. However, if the capacitance is adjusted by adjusting the electrode area, it is necessary to prepare masks of different areas so that the prepared electrode areas are different, but this is not easy to adjust the electrode area in real time. Compared with preparing a new mask, it is easier to change the thickness of the passivation layer during the preparation of the passivation layer; therefore, the embodiment of the present application changes the capacitance by changing the thickness of the passivation layer.

[0065] The present application further provides a method for preparing an array substrate, the array substrate including the array substrate as described in any one of the above items, the array substrate including a first display area and a second display area; the method for preparing the array substrate may include:

[0066] providing a substrate;

[0069] The first electrode and the third electrode form a first capacitor, the second electrode and the fourth electrode form a second capacitor, and the capacitances of the first capacitor and the second capacitor are different.

[0070] The array substrate prepared by the method for preparing an array substrate provided in an embodiment of the present application includes a first display area and a second display area, and further includes: a substrate; a first electrode layer, wherein the first electrode layer does not completely cover the substrate, the first electrode layer includes a first electrode and a second electrode, the first electrode being located in the first display area and the second electrode being located in the second display area; a second electrode layer, wherein the second electrode layer is located above the first electrode layer, the second electrode layer includes a third electrode and a fourth electrode, the third electrode being located in the first display area and electrically connected to the first electrode through a first via hole, and the fourth electrode being located in the second display area and electrically connected to the second electrode through a second via hole; wherein the first electrode and the third electrode form a first capacitor, the second electrode and the fourth electrode form a second capacitor, and the first capacitor and the second capacitor have different capacitances. By setting capacitors of different capacitances in different display areas of the array substrate, the present application can control the driving voltage of different display areas, thereby controlling the liquid crystal deflection angles of different display areas, thereby achieving adjustment of images with different viewing angles.
