Technical Field
[0001] The present disclosure relates to the field of display technology, and in particular to a display panel and a display device. Background Art
[0002] With the advancement of display technology, the requirements for display products across various industries are becoming increasingly stringent. In some display panels, a black light-shielding layer is used to cover the metal structure of the circuit layer to reduce screen reflectivity and improve the ambient contrast and display quality of the display panel. However, during the production process, the black light-shielding layer often suffers from incomplete etching, which affects the display quality of the display panel.
[0003] Therefore, how to solve the above technical problems has become one of the technical problems that need to be solved urgently at this stage. Summary of the Invention

[0006] A substrate and a driving array layer, wherein the driving array layer is located on one side of the substrate;
[0007] a light-emitting element, the light-emitting element being located on a side of the driving array layer away from the substrate;
[0008] a first light-shielding layer, the first light-shielding layer being located on a side of the light-emitting element away from the substrate;
[0009] A distance between a surface of the first light-shielding layer close to the light-emitting element and a surface of the light-emitting element away from the substrate is H0, where H0>0.
[0010] In a second aspect, based on the same inventive concept, the present disclosure provides a display device comprising the display panel described in the first aspect.
[0011] The technical solution provided by the embodiments of the present disclosure has the following advantages over the prior art:
[0012] The present disclosure provides a display panel and a display device. The display panel includes a substrate, a drive array layer located on one side of the substrate, a light-emitting element located on a side of the drive array layer away from the substrate, and a first light-shielding layer located on a side of the light-emitting element away from the substrate. The present disclosure arranges that the surface of the first light-shielding layer on the side close to the light-emitting element is at a distance greater than zero from the surface of the light-emitting element away from the substrate. That is, the first light-shielding layer does not directly contact the light-emitting element. This facilitates removal of the first light-shielding layer above the light-emitting element, thereby reducing the impact of the first light-shielding layer on the light-emitting element, thereby improving the display effect of the display panel.

[0038] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features therein can be combined with each other in the absence of conflict.
[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.
[0040] The inventors discovered during their research that in some display panels, a black shading layer is used to cover the metal structure of the circuit layer in order to reduce the screen reflectivity and improve the ambient contrast and display quality of the display panel. When the black shading layer is produced, a whole black shading layer is usually produced on the light-emitting surface side of the light-emitting element, and then the corresponding black shading layer above the light-emitting area of the light-emitting element is removed through a developing process or an ashing process. In the actual production process, it was found that the surface of the light-emitting element has many microstructures or graphic structures, and the surface is uneven, which is difficult to remove through a developing process or an ashing process, affecting the display effect. In addition, when the ashing process is used to remove the black shading layer, the black particles generated will contaminate the ashing chamber and the display panel, which not only affects the production yield of the display panel, but also increases the equipment maintenance cost.
[0041] Therefore, how to improve the above problems has become one of the technical problems that need to be solved urgently at this stage.
[0042] In view of this, the present disclosure provides a display panel and a display device to improve the display effect of the display panel.
[0043] Figure 1 FIG. 1 is a schematic top view of a display panel provided by an embodiment of the present disclosure. Figure 2 This disclosure is shown Figure 1 A cross-sectional diagram of the middle line AA', please refer to Figure 1 and Figure 2 The present disclosure provides a display panel 100, comprising:
[0044] A substrate 10 and a driving array layer 20 , wherein the driving array layer 20 is located on one side of the substrate 10 ;
[0045] The light emitting element 30 is located on a side of the driving array layer 20 away from the substrate 10;
[0046] A first light shielding layer 40 , which is located on a side of the light emitting element 30 away from the substrate 10 ;
[0047] A distance between a surface of the first light-shielding layer 40 close to the light-emitting element 30 and a surface of the light-emitting element 30 away from the substrate 10 is H0, where H0>0.
[0048] It should be noted that the drawings in this disclosure are for illustration only and do not represent the actual structure of the display panel 100. For example, the surface of the light emitting element 30 actually has many microstructures or graphic structures, which are not shown in the drawings. At the same time, for the sake of clarity, the drawings in this disclosure set transparency for some film fillings, for example, Figure 1 In the top view, transparency is set for the first light shielding layer 40. Transparency is set for some other film layers, which will be pointed out again and will not be repeated.
[0049] Specifically, the present disclosure provides a display panel 100, which includes a substrate 10, a drive array layer 20, a light-emitting element 30, and a first light-shielding layer 40. The drive array layer 20 is located on one side of the substrate 10; the light-emitting element 30 is located on a side of the drive array layer 20 away from the substrate 10. The light-emitting element 30 is electrically connected to the drive array layer 20 and emits light when driven by the drive array layer 20. The drive array layer 20 includes multiple metal structures. To cover these metal structures and reduce the reflectivity of the display panel 100, the first light-shielding layer 40 is provided on the side of the light-emitting element 30 away from the substrate 10.
[0050] It should be noted that the light emitting element 30 is electrically connected to the driving array layer 20 via the bonding structure 203 . The bonding structure 203 serves as a connecting bridge between the driving array layer 20 and the light emitting element 30 , transmitting the signal provided by the driving array layer 20 to the light emitting element 30 .
[0051] In the display panel 100 provided in the present disclosure, the surface of the first light-shielding layer 40 close to the light-emitting element 30 is at a distance H0 from the surface of the light-emitting element 30 away from the substrate 10 , and H0>0, that is, the first light-shielding layer 40 is not in direct contact with the light-emitting element 30 .
[0052] It should be noted that the surface of the light-emitting element 30 includes many microstructures or graphic structures, that is, the surface of the light-emitting element 30 is uneven. In the prior art, the first light-shielding layer 40 is directly made on the surface of the light-emitting element 30, and the first light-shielding layer 40 is in direct contact with the light-emitting element 30. When the first light-shielding layer 40 corresponding to the light-emitting element 30 is subsequently removed, the first light-shielding layer 40 cannot be completely removed due to the uneven surface of the light-emitting element 30, thereby affecting the display effect. The present disclosure sets the first light-shielding layer 40 to not be in direct contact with the light-emitting element 30. This setting is conducive to removing the first light-shielding layer 40 above the light-emitting element 30, reducing the residue of the first light-shielding layer 40, and reducing the impact of the first light-shielding layer 40 on the light-emitting element 30, thereby helping to improve the display effect of the display panel 100.
[0053] It should also be noted that the drive array layer 20 includes a transistor 21, which includes a gate 211, a source 212 and a drain 213. The control signal is input by the gate 211, and the channel region between the source 212 and the drain 213 is turned on. A path is formed between the source 212 and the drain 213, and the electrical signal can be written into the drain 213 through the source 212 and the channel region.
[0054] Please continue to refer to Figure 1 and Figure 2 Optionally, the first light shielding layer 40 includes a plurality of first openings 41 , and the first openings 41 overlap with the light emitting element 30 ;
[0055] Along the first direction F1 and / or the second direction F2, the width DF1 of at least part of the first opening portion 41 is greater than the width LF1 of the light-emitting element 30; and / or, the width DF1 of at least part of the first opening portion 41 is equal to the width LF1 of the light-emitting element 30; and / or, the width DF1 of at least part of the first opening portion 41 is less than the width LF1 of the light-emitting element 30; the first direction F1 and the second direction F2 are parallel to the plane where the display panel 100 is located.
[0056] Specifically, the first light-shielding layer 40 includes a plurality of first openings 41, which overlap with the light-emitting elements 30. Light from the light-emitting elements 30 is emitted through the first openings 41. The display panel 100 includes a plurality of light-emitting elements 30 and a plurality of first openings 41. The dimensional relationship between the first openings 41 and the light-emitting elements 30 includes the following three types: first, the width DF1 of the first opening 41 is greater than the width LF1 of the light-emitting element 30 along the first direction F1 and / or the second direction F2; second, the width DF1 of the first opening 41 is equal to the width LF1 of the light-emitting element 30 along the first direction F1 and / or the second direction F2; and third, the width DF1 of the first opening 41 is less than the width LF1 of the light-emitting element 30 along the first direction F1 and / or the second direction F2. It should be noted that in an actual display panel 100, the relationship between different light-emitting elements 30 and the first openings 41 can be any one of the above, a combination of two, or a combination of all three, and this disclosure does not specifically limit this.
[0057] In the present disclosure, the width DF1 of at least a portion of the first opening 41 is greater than the width LF1 of the light-emitting element 30; and / or the width DF1 of at least a portion of the first opening 41 is equal to the width LF1 of the light-emitting element 30; and / or the width DF1 of at least a portion of the first opening 41 is less than the width LF1 of the light-emitting element 30. The width DF1 of the first opening 41 in the display panel 100 can be greater than the width LF1 of the light-emitting element 30, equal to the width LF1 of the light-emitting element 30, or less than the width LF1 of the light-emitting element 30. The width DF1 of the first opening 41 in the display panel 100 can be the same or different, depending on the actual situation, and is not specifically limited in this disclosure.
[0058] It should be noted that the first direction F1 is parallel to the plane where the display panel 100 is located, and can be any direction within the display panel 100. For example, it can be the direction from the first electrode E1 of the light-emitting element 30 to the second electrode E2 of the light-emitting element 30. This disclosure is only described as an example and is not limited to this.
[0059] Figure 3 This disclosure is shown Figure 1 Another cross-sectional diagram along the middle line AA', please refer to Figure 1 and Figure 3 The present disclosure provides an optional embodiment in which, along the first direction F1, within the display panel 100, the width DF1 of the first opening 41 is greater than the width LF1 of the light-emitting element 30. That is, the first opening 41 and the light-emitting element 30 adopt the same dimensional relationship, and the first opening 41 is larger than the light-emitting element 30. Within the same display panel 100, the first opening 41 is larger than the light-emitting element 30. On the one hand, the identical dimensional relationship between the first opening 41 and the light-emitting element 30 facilitates the simplification of the manufacture of the display panel 100. On the other hand, the larger size of the first opening 41 than the light-emitting element 30 facilitates the transmission of light from the light-emitting element 30 through the first opening 41, thereby improving the brightness of the display panel 100.
[0060] Figure 4 This disclosure is shown Figure 1 Another cross-sectional diagram along the middle line AA', please refer to Figure 1 and Figure 4The present disclosure provides another optional embodiment in which, along the first direction F1, the width DF1 of the first opening 41 in the display panel 100 is smaller than the width LF1 of the light-emitting element 30. In this embodiment, the dimensions of the first opening 41 and the light-emitting element 30 are similarly designed, which helps simplify the manufacture of the display panel 100. In this embodiment, the dimensions of the first opening 41 are smaller than the dimensions of the light-emitting element 30. This configuration facilitates shielding of the metal structures within the drive array layer 20 by the first light-shielding layer 40, thereby reducing the reflectivity of the display panel 100 and improving the display quality of the display panel 100.
[0061] Figure 5 This disclosure is shown Figure 1 Another cross-sectional diagram along the middle line AA', please refer to Figure 1 and Figure 5 The present disclosure provides another optional embodiment in which, along the first direction F1, within the display panel 100, the width DF1 of the first opening 41 is equal to the width LF1 of the light-emitting element 30. That is, the first opening 41 and the light-emitting element 30 have the same size relationship, and the size of the first opening 41 is equal to the size of the light-emitting element 30. Within the same display panel 100, the size of the first opening 41 is equal to the size of the light-emitting element 30. On the one hand, the identical size relationship between the first opening 41 and the light-emitting element 30 facilitates the simplification of the manufacture of the display panel 100. On the other hand, the first opening 41 and the light-emitting element 30 have the same size and completely overlap, which facilitates reducing the impact on the light extraction efficiency of the light-emitting element 30 and at the same time, shields the metal structure of the drive array layer 20 as much as possible, which facilitates reducing reflectivity.
[0062] It should be noted that in the above three embodiments, in the same display panel 100, the size relationship between the first opening portion 41 and the light-emitting element 30 is the same, but the present disclosure is not limited to this. In the same display panel 100, the size relationship between the first opening portion 41 and the light-emitting element 30 may also be different, and can be designed according to specific circumstances.
[0063] Figure 6 FIG2 is a top view of another display panel provided by an embodiment of the present disclosure, please refer to FIG2 Figure 6 The present disclosure provides an optional embodiment in which, along the first direction F1, the width DF1 of at least part of the first opening portion 41 is greater than the width LF1 of the light-emitting element 30; along the second direction F2, the width DF2 of at least part of the first opening portion 41 is equal to the width LF2 of the light-emitting element 30.
[0064] Specifically, in this embodiment, a size relationship between the first opening portion 41 and the light emitting element 30 along different directions is provided. Along the first direction F1, the width DF1 of at least part of the first opening portion 41 is greater than the width LF1 of the light emitting element 30. Along the second direction F2, the width DF2 of at least part of the first opening portion 41 is equal to the width LF2 of the light emitting element 30. Please refer to Figure 6 , Figure 6 The first opening portion 411 corresponding to the light emitting element 31 has a width DF1 greater than a width LF1 of the light emitting element 31 along the first direction F1 ; and a width DF2 of the first opening portion 411 equal to a width LF2 of the light emitting element 31 along the second direction F2 .
[0065] Please continue to refer to Figure 6 The present disclosure provides another optional embodiment in which, along the first direction F1, the width DF1 of at least part of the first opening portion 41 is greater than the width LF1 of the light-emitting element 30; along the second direction F2, the width DF2 of at least part of the first opening portion 41 is greater than the width LF2 of the light-emitting element 30.
[0066] Specifically, this embodiment provides another dimensional relationship between the first opening 41 and the light-emitting element 30 along different directions. Along the first direction F1, the width DF1 of at least part of the first opening 41 is greater than the width LF1 of the light-emitting element 30. Along the second direction F2, the width DF2 of at least part of the first opening 41 is greater than the width LF2 of the light-emitting element 30. The first direction F1 and the second direction F2 intersect. This arrangement limits the width of the first opening 41 to be greater than the width of the light-emitting element 30 in two directions, which is more conducive to the light of the light-emitting element 30 passing through the first opening 41, thereby improving the brightness of the display panel 100. Please refer to Figure 6 , Figure 6 In the first opening portion 412 corresponding to the light emitting element 32 , the width DF1 of the first opening portion 412 along the first direction F1 is greater than the width LF1 of the light emitting element 32 ; the width DF2 of the first opening portion 412 along the second direction F2 is greater than the width LF2 of the light emitting element 32 .
[0067] Please continue to refer to Figure 6 The present disclosure provides another optional embodiment in which, along the first direction F1, the width DF1 of at least part of the first opening portion 41 is smaller than the width LF1 of the light-emitting element 30; along the second direction F2, the width DF2 of at least part of the first opening portion 41 is smaller than the width LF2 of the light-emitting element 30.
[0068] Specifically, in this embodiment, another size relationship between the first opening portion 41 and the light-emitting element 30 along different directions is provided. Along the first direction F1, the width DF1 of at least part of the first opening portion 41 is smaller than the width LF1 of the light-emitting element 30. Along the second direction F2, the width DF2 of at least part of the second opening portion is smaller than the width LF2 of the light-emitting element 30. The first direction F1 and the second direction F2 intersect. This arrangement limits the width of the first opening portion 41 to be smaller than the width of the light-emitting element 30 from two directions, further ensuring that the size of at least part of the first opening portion 41 in the display panel 100 is smaller than the size of the light-emitting element 30, which is more conducive to the first light-shielding layer 40 shielding the metal structure in the drive array layer 20, thereby reducing the reflectivity of the display panel 100. Please refer to Figure 6 , Figure 6 In the first opening 413 corresponding to the light emitting element 33 , the width DF1 of the first opening 413 along the first direction F1 is smaller than the width LF1 of the light emitting element 33 ; the width DF2 of the first opening 413 along the second direction F2 is smaller than the width LF2 of the light emitting element 33 .
[0069] It should be noted that in the display panel 100 provided by the present disclosure, the surface of the first light-shielding layer 40 on the side close to the light-emitting element 30 is at a distance greater than zero from the surface of the light-emitting element 30 on the side away from the substrate 10. That is, the first light-shielding layer 40 does not directly contact the light-emitting element 30. This facilitates the removal of the first light-shielding layer 40 above the light-emitting element 30, reducing the impact of the first light-shielding layer 40 on the light-emitting element 30, thereby improving the display effect of the display panel 100. At the same time, in order to reduce the reflectivity of the display panel 100, the embodiment of the present disclosure provides a first light-shielding portion 421 to block a portion of the light-emitting element 30.
[0070] Figure 7 This disclosure is shown Figure 6 An enlarged view of the middle region Q, please refer to Figure 6 and Figure 7 The present disclosure provides an optional embodiment in which the light emitting element 30 has a width x1 along the first direction F1 and a width y1 along the second direction F2; x1>y1; the first opening portion 41 has a width x2 along the first direction F1 and a width y2 along the second direction F2; x2>y2; x1-x2>y1-y2.
[0071] Specifically, in this embodiment, the widths of the light-emitting element 30 along the first direction F1 and the second direction F2 are different, with the width x1 of the light-emitting element 30 along the first direction F1 being greater than the width y1 along the second direction F2. The widths of the first opening 41 along the first direction F1 and the second direction F2 are also different, with the width x2 of the first opening 41 along the first direction F1 being greater than the width y2 along the second direction F2. Since the width of the light-emitting element 30 along the first direction F1 is greater than the width along the second direction F2, the light-emitting element 30 is shielded more along the first direction F1 than along the second direction F2, i.e., the shielding along the long side is greater than the shielding along the short side. Please refer to Figure 7 , the shielding of the light emitting element 30 along the first direction F1 is greater than the shielding of the light emitting element 30 along the second direction F2, so it can be concluded that (x1-x2) / 2>(y1-y2) / 2. Further calculation shows that x1-x2>y1-y2. Such a setting is beneficial to reducing the brightness loss of the light emitting element 30. At the same time, the first light shielding layer 40 effectively shields the metal structure of the driving array layer 20, thereby reducing the reflectivity of the display panel 100.
[0072] For example, the width of the light-emitting element 30 along the first direction F1 is x1 = 25 μm, the width of the light-emitting element 30 along the second direction F2 is y1 = 15 μm, the width of the first opening 41 along the first direction F1 is x2 = 19 μm, and the width of the first opening 41 along the second direction F2 is y2 = 13 μm. Along the first direction F1, the first light-shielding layer 40 blocks the light-emitting element 30 by a width of (x1-x2) / 2 = 3 μm; along the second direction F2, the first light-shielding layer 40 blocks the light-emitting element 30 by a width of (y1-y2) / 2 = 1 μm. The first light-shielding layer 40 blocks the light-emitting element 30 more along the first direction F1 than the second light-shielding layer 70 blocks the light-emitting element 30 along the second direction F2.
[0073] Please continue to refer to Figure 6 and Figure 7 , optionally, x1 / y1≥x2 / y2.
[0074] Specifically, the width of the light-emitting element 30 along the first direction F1 is x1, and the width along the second direction F2 is y1; x1>y1, indicating that the width of the light-emitting element 30 along the first direction F1 is greater than the width along the second direction F2; the width of the first opening 41 along the first direction F1 is x2, and the width along the second direction F2 is y2; x2>y2, indicating that the width of the first opening 41 along the first direction F1 is greater than the width along the second direction F2. The present disclosure provides an optional embodiment in which x1 / y1>x2 / y2. In this case, the shape of the first opening 41 and the shape of the second opening are not similar, and the shielding effect of the first light-shielding layer 40 on the light-emitting element 30 along the first direction F1 is greater than the shielding effect of the first light-shielding layer 40 on the light-emitting element 30 along the second direction F2. In this manner, the first light-shielding layer 40 effectively shields the metal structure of the drive array layer 20, thereby reducing the reflectivity of the display panel 100. The present disclosure provides another optional embodiment in which x1 / y1=x2 / y2. In this case, the shape of the first opening 41 and the shape of the light-emitting element 30 are similar figures, that is, the first light-shielding layer 40 shields the light-emitting element 30 in proportion, and the width of the light-emitting element 30 along the first direction F1 is greater than the width along the second direction F2. Therefore, the width of the first opening 41 along the first direction F1 is greater than the width along the second direction F2, and the ratio of the width of the first opening 41 along the first direction F1 to the width of the light-emitting element 30 along the first direction F1 is the same as the ratio of the width of the first opening 41 along the second direction F2 to the width of the light-emitting element 30 along the second direction F2. In this case, the shape of the first opening 41 and the shape of the second opening are similar figures. Such a configuration further facilitates the first light-shielding layer 40 to effectively shield the metal structure of the drive array layer 20, thereby reducing the reflectivity of the display panel 100.
[0075] Figure 8 This disclosure is shown Figure 1 A cross-sectional diagram of the middle edge BB', please refer to Figure 1 and Figure 8 The present disclosure provides an optional embodiment in which the light-emitting element 30 includes a first color light-emitting element 301 and a second color light-emitting element 302, and the operating current of the first color light-emitting element 301 is greater than the operating current of the second color light-emitting element 302; along the first direction F1, the width of the first opening portion 41 corresponding to the first color light-emitting element 301 is D1, and the width of the first opening portion 41 corresponding to the second color light-emitting element 302 is D2; D1>D2.
[0076] Specifically, the display panel 100 includes a plurality of light-emitting elements 30. In order to improve the color richness of the display panel 100, the light-emitting elements 30 include a first color light-emitting element 301 and a second color light-emitting element 302. The operating current of the first color light-emitting element 301 is greater than the operating current of the second color light-emitting element 302. Optionally, the first color light-emitting element 301 is a red light-emitting element, and the second color light-emitting element 302 is a green light-emitting element. It should be noted that the present disclosure is only described by this example and is not limited to this. For light-emitting elements 30 with different operating currents, this embodiment performs a differentiated design of the size of the first opening portion 41. Specifically, the width D1 of the first opening portion 41 corresponding to the first color light-emitting element 301 is greater than the width D2 of the first opening portion 41 corresponding to the second color light-emitting element 302, that is, the width of the first opening portion 41 corresponding to the light-emitting element 30 with a higher operating current is greater than the width of the first opening portion 41 corresponding to the light-emitting element 30 with a lower operating current.
[0077] It should be noted that the operating current of the light-emitting element 30 affects the power consumption of the display panel 100. Power consumption = operating current × voltage. Therefore, the greater the operating current of the light-emitting element 30, the higher the power consumption of the display panel 100. The operating current of the first-color light-emitting element 301 is greater than the operating current of the second-color light-emitting element 302, and the power consumption of the first-color light-emitting element 301 is greater than the power consumption of the second-color light-emitting element 302. In this embodiment, the width D1 of the first opening 41 corresponding to the first-color light-emitting element 301 is greater than the width D2 of the first opening 41 corresponding to the second-color light-emitting element 302. Given the same power consumption, the brightness of the first-color light-emitting element 301 is lower than that of the second-color light-emitting element 302. By increasing the width of the first opening 41 corresponding to the first-color light-emitting element 301, more light is emitted from the corresponding first opening 41. By increasing the first opening 41, the brightness of the first-color light-emitting element 301 is increased, thereby balancing the brightness differences between the different light-emitting elements 30.
[0078] Along the first direction F1 , the width of the first color light emitting element 301 is L1 , and the width of the second color light emitting element 302 is L2 .
[0079] Please continue to refer to Figure 1 and Figure 8 , the present disclosure provides an optional implementation scheme: D1>L1, D2>L2.
[0080] Specifically, in this embodiment, the width D1 of the first opening portion 41 corresponding to the first color light-emitting element 301 is greater than the width L1 of the first color light-emitting element 301, and the width D2 of the first opening portion 41 corresponding to the second color light-emitting element 302 is greater than the width L1 of the second color light-emitting element 302, that is, the width of the first opening portion 41 is greater than the width of the light-emitting element 30. In this way, the area of the first opening portion 41 is larger, which is beneficial to improving the brightness of the display panel 100. At the same time, the width D1 of the first opening portion 41 corresponding to the first color light-emitting element 301 is greater than the width D2 of the first opening portion 41 corresponding to the second color light-emitting element 302. Under the condition of the same power consumption, since the operating current of the first color light-emitting element 301 is greater than the operating current of the second color light-emitting element 302, the brightness of the first color light-emitting element 301 is less than the brightness of the second color light-emitting element 302. By increasing the width of the first opening portion 41 corresponding to the first color light-emitting element 301, the first color light-emitting element 301 emits more light from the corresponding first opening portion 41. By increasing the first opening portion 41, the brightness of the first color light-emitting element 301 is increased, which is conducive to balancing the brightness differences of different light-emitting elements 30.
[0081] Figure 9 This disclosure is shown Figure 1 For another cross-sectional diagram of the middle edge BB', please refer to Figure 1 and Figure 9 , the present disclosure provides an optional implementation method, D1 <L1,D2<L2。
[0082] Specifically, in this embodiment, the width D1 of the first opening portion 41 corresponding to the first color light-emitting element 301 is smaller than the width L1 of the first color light-emitting element 301, and the width D2 of the first opening portion 41 corresponding to the second color light-emitting element 302 is smaller than the width L1 of the second color light-emitting element 302, that is, the width of the first opening portion 41 is larger than the width of the light-emitting element 30. In this way, the width of the first opening portion 41 is smaller than the width of the light-emitting element 30, which is beneficial for the first light-shielding layer 40 to shield the metal structure in the driving array layer 20, thereby reducing the reflectivity of the display panel 100.
[0083] Figure 10 This disclosure is shown Figure 1 Another cross-sectional diagram along the middle line AA', please refer to Figure 1 and Figure 10The present disclosure provides an optional embodiment in which the light emitting element 30 further includes a third color light emitting element 303, and the operating current of the third color light emitting element 303 is less than the operating current of the second color light emitting element 302; along the first direction F1, the width of the first opening portion 41 corresponding to the third color light emitting element 303 is D3, and the width of the third color light emitting element 303 is L3; D1>L1, D2=L2, D3 <L3。
[0084] Specifically, the light-emitting elements 30 include a first-color light-emitting element 301, a second-color light-emitting element 302, and a third-color light-emitting element 303. The operating current of the first-color light-emitting element 301 is greater than the operating current of the second-color light-emitting element 302, and the operating current of the second-color light-emitting element 302 is greater than the operating current of the third-color light-emitting element 303. This embodiment provides a dimensional relationship between the different-color light-emitting elements 30 and the corresponding first openings 41: the width D1 of the first opening 41 corresponding to the first-color light-emitting element 301 is greater than the width L1 of the first-color light-emitting element 301; the width D2 of the first opening 41 corresponding to the second-color light-emitting element 302 is equal to the width L2 of the second-color light-emitting element 302; and the width D3 of the first opening 41 corresponding to the third-color light-emitting element 303 is less than the width L3 of the third-color light-emitting element 303.
[0085] It should be noted that for the first-color light-emitting element 301, which has the highest operating current, the width of the corresponding first opening 41 is set to be larger than the width of the first-color light-emitting element 301. In this way, the brightness of the light-emitting element 30 is increased by enlarging the first opening 41, which helps to balance the brightness differences between different light-emitting elements 30. For the third-color light-emitting element 303, which has the lowest operating current, the width of the corresponding first opening 41 is set to be smaller than the width of the third-color light-emitting element 303. In this way, the width of the first opening 41 is smaller than the width of the light-emitting element 30, which helps the first light-shielding layer 40 shield the metal structures within the drive array layer 20, thereby reducing the reflectivity of the display panel 100. For the second-color light-emitting element 302, which has an intermediate operating current, the width of the corresponding first opening 41 is set to be equal to the width of the second-color light-emitting element 302.
[0086] Optionally, the first color may be red, the second color may be green, and the third color may be blue. It should be noted that the present disclosure is only described by this example and is not limited thereto.
[0087] Please refer to Figure 1 and Figure 2 The present disclosure provides an optional embodiment in which the first light-shielding layer 40 includes a light-shielding portion 42 , and at least a portion of the light-shielding portion 42 overlaps with the light-emitting element 30 .
[0088] It should be noted that the light shielding portion 42 overlapping the light emitting element 30 means that the orthographic projection of the light shielding portion 42 on the substrate 10 overlaps with the orthographic projection of the light emitting element 30 on the substrate 10 along a direction perpendicular to the display panel 100 .
[0089] Specifically, the first light shielding layer 40 includes a plurality of light shielding portions 42, which are used to shield the metal structure of the drive array layer 20, thereby reducing the reflectivity of the display panel 100. In this embodiment, at least a portion of the light shielding portions 42 overlaps with the light emitting elements 30. This facilitates shielding the light shielding portions 42 from the metal structure that overlaps with the light emitting elements 30, thereby further reducing the reflectivity of the display panel 100.
[0090] Please continue to refer to Figure 1 and Figure 2 Optionally, the overlapping width of the light shielding portion 42 and the light emitting element 30 is W, 0μm<W≤3μm.
[0091] Specifically, the edges of the light-emitting elements 30 emit relatively weak light. Therefore, shielding the edges of the light-emitting elements 30 with the light-shielding portion 42 minimizes the brightness of the light-emitting elements 30 while also shielding the metal structure of the drive array layer 20, thereby reducing the reflectivity of the display panel 100. This disclosure provides an embodiment in which the light-shielding portion 42 shields the width of the light-emitting elements 30. The overlap width W between the light-shielding portion 42 and the light-emitting elements 30 is set to 0μm < W ≤ 3μm. When the overlap width W between the light-shielding portion 42 and the light-emitting elements 30 exceeds 3μm, excessive shielding of the light-emitting elements 30 may significantly affect the brightness of the light-emitting elements 30, thereby affecting the display quality of the display panel. Therefore, the overlap width W between the light-shielding portion 42 and the light-emitting elements 30 is set to 0μm < W ≤ 3μm. This proper shielding of the edges of the light-emitting elements 30 by the light-shielding portion 42 helps shield the metal structure of the drive array layer 20, reduces the reflectivity of the display panel 100, and thereby improves the display quality of the display panel 100. The present disclosure provides an optional implementation manner that the width W of the light-shielding portion 42 overlapping with the light-emitting element 30 is 1 μm; the present disclosure provides another optional implementation manner that the width W of the light-shielding portion 42 overlapping with the light-emitting element 30 is 2 μm; the present disclosure further provides an optional implementation manner that the width W of the light-shielding portion 42 overlapping with the light-emitting element 30 is 3 μm.
[0092] It should be noted that the overlapping width W of the light shielding portion 42 and the light emitting element 30 refers to the overlapping width of the light shielding portion 42 and one side of the light emitting element 30 .
[0093] Please refer to Figure 6 and Figure 7The present disclosure provides an optional embodiment in which the width of the light-emitting element 30 along the first direction F1 is greater than the width of the light-emitting element 30 along the second direction F2, the first direction F1 and the second direction F2 intersect, the first direction F1 is parallel to the plane where the display panel 100 is located, and the second direction F2 is parallel to the plane where the display panel 100 is located;
[0094] Along the first direction F1 , the light shielding portion 42 overlaps the light emitting element 30 by a width of W1 ; along the second direction F2 , the light shielding portion 42 overlaps the light emitting element 30 by a width of W2 ; W1 > W2 .
[0095] Specifically, the width of the light-emitting element 30 along the first direction F1 is greater than the width of the light-emitting element 30 along the second direction F2. The width of the region of the light-emitting element 30 with relatively low brightness along the first direction F1 is greater than the width of the region of the light-emitting element 30 with relatively low brightness along the second direction F2. Therefore, the width of the light-shielding portion 42 overlapping the light-emitting element 30 along the first direction F1 is greater than the width of the light-shielding portion 42 overlapping the light-emitting element 30 along the second direction F2. In this way, by shielding the region of relatively low brightness of the light-emitting element 30, the metal structure of the drive array layer 20 is shielded, thereby reducing reflectivity and improving the display quality of the display panel 100.
[0096] Please refer to Figure 9 , the present disclosure provides an optional embodiment in which the light emitting element 30 includes a first color light emitting element 301 and a second color light emitting element 302, and the operating current of the first color light emitting element 301 is greater than the operating current of the second color light emitting element 302;
[0097] Along the first direction F1 , the overlapping width of the light shielding portion 42 and the first color light emitting element 301 is r, and the overlapping width of the light shielding portion 42 and the second color light emitting element 302 is g. The first direction F1 is parallel to the plane of the display panel 100 ; r<g.
[0098] Specifically, to enhance the color richness of the display panel 100, the display panel 100 includes light-emitting elements 30 of multiple colors. The light-emitting elements 30 include first-color light-emitting elements 301 and second-color light-emitting elements 302. The light-emitting elements 30 of different colors require different operating currents, with the first-color light-emitting elements 301 operating at a higher current than the second-color light-emitting elements 302. The operating current affects the power consumption of the display panel 100. Power consumption = operating current × voltage. Therefore, the greater the operating current, the higher the power consumption of the display panel 100. The operating current of the first-color light-emitting elements 301 is higher than that of the second-color light-emitting elements 302. Therefore, the power consumption of the first-color light-emitting elements 301 is higher than that of the second-color light-emitting elements 302. With the same power consumption, the brightness of the first-color light-emitting element 301 is lower than that of the second-color light-emitting element 302. In this embodiment, the width r of the overlap between the light-shielding portion 42 and the first-color light-emitting element 301 is smaller than the width g of the overlap between the light-shielding portion 42 and the second-color light-emitting element 302. By reducing the width r of the light-shielding portion 42 blocking the first-color light-emitting element 301, the first-color light-emitting element 301 is allowed to emit more light. By reducing the overlap between the light-shielding portion 42 and the first-color light-emitting element 301, the brightness of the first-color light-emitting element 301 is increased, thereby balancing the brightness differences between the different light-emitting elements 30. Furthermore, the light-shielding portion 42 shields the metal structure of the drive array layer 20, thereby reducing the reflectivity of the display panel 100 and improving the display quality of the display panel 100.
[0099] It should be noted that the display panel 100 may include light-emitting elements 30 of colors such as red, green, and blue. Light-emitting elements 30 of different colors correspond to different operating currents. Optionally, the first color is red and the second color is green. This disclosure is merely illustrative and is not intended to be limiting. For example, the first color may also be green and the second color may also be blue.
[0100] Figure 11 This disclosure is shown Figure 1 A cross-sectional diagram of the light emitting element along CC', please refer to Figure 1 and Figure 11The present disclosure provides an optional embodiment in which the light-emitting element 30 includes a stacked epitaxial layer 3011, a first semiconductor layer 3012, a quantum well layer 3013, and a second semiconductor layer 3014; the first semiconductor layer 3012 is located on one side of the epitaxial layer 3011, the quantum well layer 3013 is located on a side of the first semiconductor layer 3012 away from the epitaxial layer 3011, and the second semiconductor layer 3014 is located on a side of the quantum well layer 3013 away from the epitaxial layer 3011; along a direction perpendicular to the display panel 100, the orthographic projection of the quantum well layer 3013 on the epitaxial layer 3011 is located within the orthographic projection of the first semiconductor layer 3012 on the epitaxial layer 3011. The light-emitting element 30 also includes a first electrode E1 and a second electrode E2. The first electrode E1 is electrically connected to the first semiconductor layer 3012, and the second electrode E2 is electrically connected to the second semiconductor layer 3014. Along a direction perpendicular to the display panel 100, the first electrode E1 does not overlap with the quantum well layer 3013, and the second electrode E2 overlaps with the quantum well layer 3013.
[0101] Specifically, this embodiment provides a film structure of a light-emitting element 30. Specifically, along a direction perpendicular to the plane of the display panel 100 (third direction F3), the light-emitting element 30 includes a stacked epitaxial layer 3011, a first semiconductor layer 3012, a quantum well layer 3013, and a second semiconductor layer 3014. The orthographic projection area of the quantum well layer 3013 on the epitaxial layer 3011 along the third direction F3 is smaller than the orthographic projection area of the first semiconductor layer 3012 on the epitaxial layer 3011 along the third direction F3. That is, the quantum well layer 3013 and the first semiconductor layer 3012 do not completely overlap. The light-emitting element 30 also includes a first electrode E1 and a second electrode E2. The first electrode E1 is located on a side of the first semiconductor layer 3012 away from the epitaxial layer 3011 and is electrically connected to the first semiconductor layer 3012. The first electrode E1 does not overlap with the quantum well layer 3013 along the third direction F3. The second electrode E2 is located on a side of the second semiconductor layer 3014 away from the quantum well layer 3013 and is electrically connected to the second semiconductor layer 3014 . The second electrode E2 overlaps the quantum well layer 3013 along the third direction F3 .
[0102] Furthermore, the present disclosure provides an optional embodiment in which the first semiconductor layer 3012 is a P-type semiconductor layer, the second semiconductor layer 3014 is an N-type semiconductor layer, and the quantum well layer 3013 is located between the first semiconductor layer 3012 and the second semiconductor layer 3014. Holes provided by the first semiconductor layer 3012 and electrons provided by the second semiconductor layer 3014 recombine in the quantum well layer 3013 to produce light. It should be noted that the present disclosure uses this example only to illustrate the light-emitting principle of the light-emitting element 30 and is not limited thereto.
[0103] Figure 12FIG. 1 is a schematic top view of a light emitting element provided by an embodiment of the present disclosure. Figure 13 The figure shows a schematic diagram of the brightness of a light emitting element provided by an embodiment of the present disclosure. Please refer to Figure 1 、 Figures 11 to 13 It should also be noted that the light-emitting principle of the light-emitting element 30 is that holes and electrons recombine in the quantum well layer 3013 to achieve light emission. Therefore, the light-emitting intensity corresponding to the area where the quantum well layer 3013 is located is stronger than that in other areas. However, the quantum well layer 3013 is not located at the center of the light-emitting element 30. The structure of the light-emitting element 30 is not completely symmetrical, and its light emission is also asymmetric. Figure 13 The asymmetry of the light-emitting element 30 is shown. Based on this, the present disclosure provides an optional embodiment in which, along the direction from the first electrode E1 to the second electrode E2, the overlapping width of the light-shielding portion 42 and the light-emitting element 30 on the side close to the first electrode E1 is d1, and the overlapping width of the light-shielding portion 42 and the light-emitting element 30 on the side close to the second electrode E2 is d2; d1>d2.
[0104] Specifically, the light-emitting element 30 includes a first electrode E1 and a second electrode E2. The first electrode E1 is electrically connected to the first semiconductor layer 3012, and the second electrode E2 is electrically connected to the second semiconductor layer 3014. A quantum well layer 3013 is located between the first and second semiconductor layers 3012, 3014. Holes and electrons generated in the first and second semiconductor layers 3012, 3014 recombine in the quantum well layer 3013 to emit light. Along the third direction F3, the first electrode E1 and the quantum well layer 3013 do not overlap, while the second electrode E2 and the quantum well layer 3013 overlap. Therefore, the luminous intensity on the side of the light-emitting element 30 closer to the first electrode E1 is lower than the luminous intensity on the side of the light-emitting element 30 closer to the second electrode E2. Therefore, in this embodiment, the overlapping width of the light shielding portion 42 and the side of the light-emitting element 30 closer to the first electrode E1 is greater than the overlapping width of the light shielding portion 42 and the side of the light-emitting element 30 closer to the second electrode E2. In other words, the overlapping width of the light shielding portion 42 and the side of the light-emitting element 30 with lower luminous intensity is greater than the overlapping width of the light shielding portion 42 and the side of the light-emitting element 30 with higher luminous intensity. This arrangement helps fully utilize the light emitted by the light-emitting element 30, thereby reducing the power consumption of the display panel 100. At the same time, the light shielding portion 42 effectively blocks the metal structure of the drive array layer 20, which helps reduce the reflectivity of the display panel 100 and improves the display effect of the display panel 100.
[0105] Figure 14 This disclosure is shown Figure 1 Another cross-sectional diagram along the middle line AA', please refer to Figure 1 and Figure 14The present disclosure provides an optional embodiment in which the display panel 100 further includes a barrier layer 50 , which is located between the light emitting element 30 and the first light shielding layer 40 , and the barrier layer 50 is in direct contact with the light emitting element 30 and the first light shielding layer 40 , respectively.
[0106] Specifically, the display panel 100 provided in the present disclosure includes a drive array layer 20, a light-emitting element 30, and a first light-shielding layer 40. The first light-shielding layer 40 is located on the side of the light-emitting element 30 away from the substrate 10. The first light-shielding layer 40 is used to shield the metal structures in the drive array layer 20, thereby reducing the reflectivity of the display panel 100. The present disclosure also provides that the surface of the first light-shielding layer 40 near the light-emitting element 30 is at a distance H0 greater than 0 from the surface of the light-emitting element 30 away from the substrate 10. That is, the first light-shielding layer 40 does not directly contact the light-emitting element 30. This facilitates the removal of the first light-shielding layer 40 above the light-emitting element 30, thereby reducing the impact of the first light-shielding layer 40 on the light-emitting element 30, thereby improving the display quality of the display panel 100. Regarding the non-direct contact between the first light-shielding layer 40 and the light-emitting element 30, the present disclosure provides an optional embodiment in which a barrier layer 50 is disposed between the light-emitting element 30 and the first light-shielding layer 40, with the barrier layer 50 directly contacting both the light-emitting element 30 and the first light-shielding layer 40. Alternatively, the barrier layer 50 may be an organic layer or an inorganic layer, which is not specifically limited in this disclosure. The barrier layer 50 prevents the first light shielding layer 40 from directly contacting the light emitting element 30 layer, thereby facilitating the removal of the first light shielding layer 40 above the light emitting element 30, thereby improving the display effect of the display panel 100.
[0107] Regarding the material of barrier layer 50, this disclosure provides an optional embodiment in which barrier layer 50 is made of photoresist, specifically acrylic photoresist. Another optional embodiment provided by this disclosure is that barrier layer 50 is formed using inkjet-printed transparent ink. It should be noted that this disclosure is merely an example and is not intended to be limiting. In actual use, appropriate materials can be selected based on actual needs.
[0108] It should be noted that the barrier layer 50 is located on the side of the light emitting element 30 away from the substrate 10 , and other film layers are also included between the barrier layer 50 and the driving array layer 20 . Figure 15 This disclosure is shown Figure 1 Another cross-sectional diagram along the middle line AA', please refer to Figure 1 and Figure 15 The present disclosure provides an optional embodiment in which the display panel 100 further includes a filling layer 60 and a second light-shielding layer 70 , the filling layer 60 is located between the driving array layer 20 and the blocking layer 50 , the filling layer 60 and the blocking layer 50 include a recessed portion 506 , and the second light-shielding layer 70 fills the recessed portion 506 .
[0109] Specifically, a filling layer 60 is further included between the driving array layer 20 and the blocking layer 50. The filling layer 60 and the blocking layer 50 jointly cover the light-emitting element 30 in the display panel 100 and the metal structure in the driving array layer 20. On the one hand, this is beneficial for isolating water and oxygen, protecting the light-emitting element 30 and the driving circuit layer, and improving the stability of the display panel 100; on the other hand, after the light-emitting element 30 is transferred, flattening is performed to prevent the first light-shielding layer 40 from directly contacting the light-emitting element 30 layer, thereby facilitating the removal of the first light-shielding layer 40 corresponding to the light-emitting element 30, which is beneficial for improving the display effect of the display panel 100. Both the blocking layer 50 and the filling layer 60 include a recessed portion 506. The display panel 100 also includes a second light-shielding layer 70, which fills the recessed portion 506 and forms a second light-shielding layer 70 surrounding the light-emitting element 30. The second light-shielding layer 70 covers the metal area surrounding the light-emitting element 30, preventing light from the light-emitting element 30 from leaking onto the metal structure of the drive array layer 20. This improves brightness fluctuations caused by light-induced leakage and enhances the reliability of the display panel 100. This further shields the metal structure of the drive array layer 20, helps reduce the reflectivity of the display panel 100, and improves the display quality of the display panel 100. It also helps prevent light from one light-emitting element 30 from being emitted into another light-emitting element 30, thereby avoiding light mixing between light-emitting elements 30 of different colors.
[0110] Please refer to Figure 1 and Figure 15 Optionally, the barrier layer 50 and the filling layer 60 include organic materials, and the barrier layer 50 and the filling layer 60 are manufactured using the same process.
[0111] Specifically, the filling layer 60 and the barrier layer 50 jointly cover the light-emitting element 30 in the display panel 100 and the metal structure in the drive array layer 20. On the one hand, this helps to isolate water and oxygen, protect the light-emitting element 30 and the drive circuit layer, and improve the stability of the display panel 100. On the other hand, after the light-emitting element 30 is transferred, it is flattened to prevent the first light-shielding layer 40 from directly contacting the light-emitting element 30 layer, thereby facilitating the removal of the first light-shielding layer 40 corresponding to the light-emitting element 30, which helps to improve the display effect of the display panel 100. The barrier layer 50 and the filling layer 60 may include organic materials. The present disclosure provides an optional embodiment in which the filling layer 60 can be made of the same material and the same process as the barrier layer 50. This is conducive to simplifying the manufacturing process and improving production efficiency. The present disclosure provides another optional embodiment in which the filling layer 60 and the barrier layer 50 are made in steps using different materials. The present disclosure does not make specific restrictions and can be selected according to actual needs.
[0112] Figure 16 FIG2 is a top view of a light emitting element and a second light shielding layer provided by an embodiment of the present disclosure. Figure 1 、 Figure 15 and Figure 16 The present disclosure provides an optional embodiment in which the recessed portion 506 and the light emitting element 30 do not overlap.
[0113] Specifically, the provision of the filling layer 60 and the barrier layer 50 prevents direct contact between the first light-shielding layer 40 and the light-emitting element 30, thereby facilitating the removal of the first light-shielding layer 40 corresponding to the light-emitting element 30, thereby improving the display quality of the display panel 100. The provision of the recessed portion 506 in the filling layer 60 and the barrier layer 50 is used to fill the second light-shielding layer 70, which is used to shield the metal structures in the drive array layer 20. In this embodiment, the recessed portion 506 does not overlap with the light-emitting element 30, and thus, the second light-shielding layer 70 does not overlap with the light-emitting element 30. This helps reduce the impact of the second light-shielding layer 70 on the brightness of the light-emitting element 30, thereby improving the display quality of the display panel 100.
[0114] It should be noted that, along the third direction F3, the recessed portion 506 may penetrate part of the barrier layer 50 and part of the filling layer 60, or may penetrate all of the barrier layer 50 and all of the filling layer 60, although this is not specifically limited in this disclosure. When the recessed portion 506 penetrates all of the barrier layer 50 and all of the filling layer 60, the second light-shielding layer 70 envelops the light-emitting element 30, further preventing light from the light-emitting element 30 from leaking onto the metal structure of the drive array layer 20, thereby improving brightness fluctuations caused by light-induced leakage, and further enhancing the reliability of the display panel 100.
[0115] Figure 17 This disclosure is shown Figure 1 A cross-sectional diagram of the midline DD', please refer to Figure 1 and Figure 17 The present disclosure provides an optional embodiment in which the display panel 100 includes a first display area AA1 and a second display area AA2; the first light-shielding layer 40 includes a light-shielding portion 42, and at least a portion of the light-shielding portion 42 overlaps with the light-emitting element 30; in the first display area AA1, the width of the overlap between the light-shielding portion 42 and the light-emitting element 30 is D01; in the second display area AA2, the width of the overlap between the light-shielding portion 42 and the light-emitting element 30 is D02; D01<D02.
[0116] Specifically, the first light-shielding layer 40 includes a light-shielding portion 42, which is used to shield the metal structure of the drive array layer 20, thereby reducing the reflectivity of the display panel 100. In this embodiment, at least a portion of the light-shielding portion 42 overlaps with the light-emitting element 30. This facilitates shielding the light-shielding portion 42 from the metal structure that overlaps the light-emitting element 30, thereby further reducing the reflectivity of the display panel 100.
[0117] The display panel 100 includes a first display area AA1 and a second display area AA2. Within the first display area AA1, the overlap width D01 of the light shielding portion 42 and the light-emitting element 30 is smaller than the overlap width D02 of the light shielding portion 42 and the light-emitting element 30 within the second display area AA2. Consequently, the first display area has a higher brightness than the second display area, while the second display area has a lower reflectivity than the first display area. By differentiating the overlap widths of the light shielding portion 42 and the light-emitting element 30 in different display areas of the display panel 100, the different requirements of each display area are met, thereby improving the overall display quality of the display panel 100.
[0118] Optionally, the first display area AA1 includes a sensor (not shown in the figure). The present disclosure provides an optional embodiment in which the first display area AA1 includes a camera, and the camera is located in area C2. The sensor has a great influence on the light efficiency of the display panel 100. Therefore, it is necessary to improve the light efficiency of the display panel 100 by increasing the brightness of the first display area AA1. Therefore, the width D01 of the overlap between the shading portion 42 and the light-emitting element 30 in the first display area AA1 is set to be smaller than the width D02 of the overlap between the shading portion 42 and the light-emitting element 30 in the second display area AA2. It should be noted that the present disclosure is only described as an example and is not limited to this.
[0119] It should be noted that, in some optional embodiments, in the first display area AA1, the shading portion 42 does not overlap with the light-emitting element 30, that is, the width D1 of the first opening portion 41 corresponding to the light-emitting element 30 is greater than the width L1 of the light-emitting element 30. This setting is more conducive to improving the brightness of the first display area, thereby improving the display effect of the display panel.
[0120] Please refer to Figure 1 and Figure 2 Optionally, the thickness of the first light-shielding layer 40 is h, 1 μm≤h≤10 μm.
[0121] Specifically, the first light-shielding layer 40 is primarily used to shield the metal structure of the drive array layer 20, thereby reducing the reflectivity of the display panel 100. When the thickness h of the first light-shielding layer 40 is less than 1 μm, the first light-shielding layer 40 is relatively thin and has a poor shielding effect. When the thickness h of the first light-shielding layer 40 is greater than 10 μm, the first light-shielding layer 40 is relatively thick, which affects both the thickness of the display panel 100 and the light efficiency of the display panel 100. Therefore, setting the thickness h of the first light-shielding layer 40 to 1 μm ≤ h ≤ 10 μm not only effectively shields the metal structure of the drive array layer 20, but also reduces the impact of the light-shielding layer on the light efficiency of the display panel 100, thereby comprehensively improving the display effect of the display panel 100. The present disclosure provides an optional implementation manner in which the thickness of the first light-shielding layer 40 is h = 2 μm; the present disclosure provides another optional implementation manner in which the thickness of the first light-shielding layer 40 is h = 3 μm; the present disclosure provides yet another optional implementation manner in which the thickness of the first light-shielding layer 40 is h = 5 μm; the present disclosure provides yet another optional implementation manner in which the thickness h of the first light-shielding layer 40 is set to 1 μm<h≤7 μm; the present disclosure provides yet another optional implementation manner in which the thickness h of the first light-shielding layer 40 is set to 3 μm≤h≤8 μm.
[0122] Please continue to refer to Figure 1 and Figure 2 The display panel 100 provided in the present disclosure includes a substrate 10, a drive array layer 20, a light-emitting element 30, and a first light-shielding layer 40. The drive array layer 20 is located on one side of the substrate 10; the light-emitting element 30 is located on the side of the drive array layer 20 away from the substrate 10; and the drive array layer 20 includes multiple metal structures. In order to cover the metal structures and reduce the reflectivity of the display panel 100, a first light-shielding layer 40 is provided on the side of the light-emitting element 30 away from the substrate 10. In the display panel 100 provided in the present disclosure, the distance H0 between the surface of the first light-shielding layer 40 close to the light-emitting element 30 and the surface of the light-emitting element 30 away from the substrate 10 is greater than 0, that is, the first light-shielding layer 40 is not in direct contact with the light-emitting element 30. This arrangement facilitates the removal of the first light-shielding layer 40 above the light-emitting element 30, reduces the impact of the first light-shielding layer 40 on the light-emitting element 30, and thereby facilitates improving the display effect of the display panel 100. Furthermore, H0 ≥ 1 μm.
[0123] Specifically, the size of H0 affects the reflectivity of the display panel 100 at wide viewing angles. The larger H0 is, the greater the reduction in brightness at wide viewing angles, resulting in lower brightness. Conversely, the smaller H0 is, the less the reduction in brightness at wide viewing angles, resulting in higher brightness. When H0 is less than 1 μm, the brightness at wide viewing angles is high, which is detrimental to the privacy protection performance of the display panel 100. Therefore, a distance H0 of ≥ 1 μm is provided between the surface of the first light-shielding layer 40 proximal to the light-emitting element 30 and the surface of the light-emitting element 30 distal to the substrate 10. Within this range, the distance can be set based on actual needs, which is beneficial for improving the privacy protection performance of the display panel 100. The present disclosure provides an optional embodiment in which the distance H0 between the surface of the first light-shielding layer 40 close to the light-emitting element 30 and the surface of the light-emitting element 30 away from the substrate 10 is 1 μm; the present disclosure provides another optional embodiment in which the distance H0 between the surface of the first light-shielding layer 40 close to the light-emitting element 30 and the surface of the light-emitting element 30 away from the substrate 10 is 3 μm; the present disclosure provides still another optional embodiment in which the distance H0 between the surface of the first light-shielding layer 40 close to the light-emitting element 30 and the surface of the light-emitting element 30 away from the substrate 10 is 8 μm; the present disclosure provides still another optional embodiment in which the distance between the surface of the first light-shielding layer 40 close to the light-emitting element 30 and the surface of the light-emitting element 30 away from the substrate 10 is 4 μm≤H0≤7 μm.
[0124] Figure 18 This disclosure is shown Figure 1 Another cross-sectional diagram along the middle edge BB', please refer to Figure 18 Optionally, the driving array layer 20 includes a plurality of transistors 21 and an insulating layer 22, the insulating layer 22 covers the transistors 21; the driving array layer 20 includes a clearance area C1, within the clearance area C1, the insulating layer 22 of the driving array layer 20 includes a groove 220; the width of the clearance area overlapping the light shielding portion 42 is S, S ≥ 1 μm.
[0125] Specifically, the display panel 100 includes a drive array layer 20, which includes a plurality of transistors 21 and an insulating layer 22 covering the transistors 21. The drive array layer 20 also includes a clearance area C1, which does not include the transistors 21 and other circuit structures such as metal traces. Within the clearance area C1, the insulating layer 22 includes a groove 220. In this embodiment, the width S of the overlap between the light shielding portion 42 and the clearance area C1 is set to be ≥ 1 μm. When the width S of the overlap between the light shielding portion 42 and the clearance area C1 is less than 1 μm, the light shielding portion 42 cannot effectively block the transistors 21 adjacent to the clearance area C1, resulting in metal light leakage at a wide viewing angle. Therefore, the present disclosure sets the width S of the overlap between the clearance area C1 and the light shielding portion 42 to be ≥ 1 μm. This setting facilitates the light shielding portion 42 to effectively block the drive array layer 20, improves the metal light leakage problem at a wide viewing angle, and thereby improves the display effect of the display panel 100. The present disclosure provides an optional implementation manner in which the width of the overlap between the clearance area C1 and the light-shielding portion 42 is S=2μm; the present disclosure provides another optional implementation manner in which the width of the overlap between the clearance area C1 and the light-shielding portion 42 is S=3μm; the present disclosure provides yet another optional implementation manner in which the width of the overlap between the clearance area C1 and the light-shielding portion 42 is S=5μm; the present disclosure provides yet another optional implementation manner in which the width of the overlap between the clearance area C1 and the light-shielding portion 42 is 1.5μm≤S≤2.5μm.
[0126] It should be noted that the clearance area C1 may be a transparent area in the transparent display panel, in which no light emitting elements are included, and the drive array layer does not include metal structures such as transistors and first traces. This disclosure is merely described as an example and is not limited thereto.
[0127] Figure 19 This disclosure is shown Figure 1 Another cross-sectional diagram of the center line CC', please refer to Figure 1 and Figure 19 The present disclosure provides an optional embodiment in which the first light-shielding layer 40 includes a first light-shielding portion 421 and a second light-shielding portion 422; the driving array layer 20 includes a plurality of transistors 21 and a plurality of first traces 24; the first light-shielding portion 421 overlaps with the transistors 21, the second light-shielding portion 422 overlaps with the first traces 24, and the first light-shielding portion 421 and the second light-shielding portion 422 are independent of each other.
[0128] Specifically, the drive array layer 20 includes a transistor 21 and a first wiring 24. The first light shielding layer 40 is used to shield the transistor 21 and the first wiring 24, thereby reducing the reflectivity of the display panel 100. The first light shielding layer 40 includes a first light shielding portion 421 and a second light shielding portion 422. The first light shielding portion 421 is used to shield the transistor 21, and the first light shielding portion 421 is arranged to overlap with the transistor 21. The second light shielding portion 422 is used to shield the first wiring 24, and the second light shielding portion 422 is arranged to overlap with the transistor 21. In this way, the present disclosure provides the first light shielding portion 421 and the second light shielding portion 422 to shield the transistor 21 and the first wiring 24, respectively, which is beneficial for effectively shielding the metal structure in the drive array layer 20, thereby facilitating the reduction of the reflectivity of the display panel 100 and improving the display effect of the display panel 100.
[0129] Please continue to refer to Figure 19 Furthermore, the present disclosure provides an optional implementation manner in which the width of the second light shielding portion 422 is smaller than the width of the first light shielding portion 421 .
[0130] Specifically, the display panel 100 includes a first light shielding layer 40, which includes a first light shielding portion 421 and a second light shielding portion 422. The drive array layer 20 includes a transistor 21 and a first trace 24. Along the third direction F3, the first light shielding layer 40 overlaps with the transistor 21, shielding it. The second light shielding layer 70 overlaps with the first trace 24, shielding it. This effectively shields the metal structures in the drive array layer 20, thereby reducing the reflectivity of the display panel 100 and improving the display quality of the display panel 100. Since the width of the transistor 21 is generally greater than the width of the first trace 24, in this embodiment, the width of the second shielding portion is smaller than the width of the first shielding portion. This further facilitates shielding of the transistor 21 and the first trace 24. It also reduces unnecessary shielding, which helps increase the opening area of the first light shielding layer 40, thereby improving the display quality of the display panel 100.
[0131] Please refer to Figure 1 and Figure 2 The present disclosure provides an optional implementation manner in which the display panel 100 includes a gate driving circuit and a pixel driving circuit, and the first light shielding portion 421 overlaps with the gate driving circuit and the pixel driving circuit.
[0132] It should be noted that the complete gate driving circuit and pixel driving circuit are not shown in the accompanying drawings. The gate driving circuit and the pixel driving circuit are both located in the driving array layer 20. The embodiment of the present disclosure aims to use the first shading layer 40 to shield the metal structure in the driving array layer 20.
[0133] Specifically, the display panel 100 includes a gate driver circuit and a pixel driver circuit. The pixel driver circuit is used to drive the light-emitting element 30 to emit light, and the gate driver circuit is used to provide a scanning signal to the pixel driver circuit. The first light shielding portion 421 overlaps with the gate driver circuit and the pixel driver circuit, shielding the metal structure of the drive array layer 20, thereby reducing the reflectivity of the display panel 100 and improving the display effect of the display panel 100.
[0134] It should also be noted that the pixel driving circuit can be a plurality of pixel driving circuits arranged in an array. The pixel driving circuit receives a scanning signal provided by a gate driving circuit and is turned on or off under the action of the scanning signal to provide a light-emitting signal to the light-emitting element 30, or to stop providing a light-emitting signal to the light-emitting element 30. The pixel driving circuit may include one or more transistors. The drawings of this disclosure illustrate the pixel driving circuit as an example of a circuit including one transistor. The pixel driving circuit may also be a "2T1C" circuit including two transistors and a storage capacitor, or a "7T1C" circuit. Here, "T" represents a transistor and "C" represents a storage capacitor. The embodiments of this disclosure do not specifically limit the specific structure of the pixel driving circuit and can be designed according to actual needs and the type of display panel 100. Furthermore, the transistor may include a source, a drain and a gate. The control signal is connected by the gate, the channel region between the source and the drain is turned on, a path is formed between the source and the drain, and the electrical signal can be written to the drain through the source and the channel region.
[0135] Figure 20 This disclosure is shown Figure 1 Another cross-sectional diagram of the center line CC', please refer to Figure 20 The present disclosure provides an optional embodiment in which the first light shielding layer 40 includes a plurality of first openings 41 , and the first openings 41 only overlap with the light emitting element 30 .
[0136] Specifically, the display panel 100 includes a first light-shielding layer 40, which is used to shield the metal structure of the drive array layer 20, thereby reducing the reflectivity of the display panel 100. In this embodiment, the first opening 41 of the first light-shielding layer 40 overlaps only with the light-emitting element 30, that is, the first opening 41 is provided only above the light-emitting element 30. This arrangement further facilitates shielding the drive array layer 20, reduces the reflectivity of the display panel 100, and improves the display effect of the display panel 100.
[0137] Figure 21 This disclosure is shown Figure 1 Another cross-sectional diagram of the center line CC', please refer to Figure 1 and Figure 21The present disclosure provides an optional embodiment, further comprising a barrier layer 50 and a second light shielding layer 70, wherein the barrier layer 50 is located between the driving array layer 20 and the first light shielding layer 40, and the barrier layer 50 is in direct contact with the light emitting element 30 and the first light shielding layer 40 respectively, and wraps the light emitting element 30;
[0138] The second light shielding layer 70 is located on a side of the first light shielding layer 40 close to the light emitting element 30 . The second light shielding layer 70 is in direct contact with the driving array layer 20 and the first light shielding layer 40 . The second light shielding layer 70 is at least located between adjacent light emitting elements 30 .
[0139] Specifically, in this embodiment, the display panel 100 includes a blocking layer 50, a first light-shielding layer 40, and a second light-shielding layer 70. The first light-shielding layer 40 is located on the side of the light-emitting element 30 away from the substrate 10. The blocking layer 50 directly contacts the light-emitting element 30 and wraps around the light-emitting element 30, preventing direct contact between the light-emitting element 30 and the first light-shielding layer 40. The first opening 41 only overlaps the light-emitting element 30. When forming the first opening 41, it is convenient to remove the first light-shielding layer 40 above the light-emitting element 30, which helps reduce the impact of the first light-shielding layer 40 on the light-emitting element 30, thereby improving the display quality of the display panel 100. At the same time, the first light-shielding layer 40 effectively blocks the drive array layer 20, which helps reduce the reflectivity of the display panel 100. This embodiment further provides a second light-shielding layer 70 between the drive array layer 20 and the first light-shielding layer 40. The second light-shielding layer 70 covers the metal area surrounding the light-emitting element 30, preventing light from the light-emitting element 30 from leaking onto the metal structure of the drive array layer 20. This reduces brightness fluctuations caused by light-induced leakage and enhances the reliability of the display panel 100. This further shields the metal structure of the drive array layer 20, thereby reducing the reflectivity of the display panel 100 and improving the display quality of the display panel 100.
[0140] Please continue to refer to Figure 1 and Figure 21 The present disclosure provides an optional embodiment in which the first light-shielding layer 40 and the second light-shielding layer 70 are integrally formed.
[0141] It should be noted that the first light shielding layer 40 and the second light shielding layer 70 are integrally formed in the same process, which is beneficial to simplifying the manufacturing process of the display panel 100 and improving production efficiency.
[0142] Figure 22 This disclosure is shown Figure 1 Another cross-sectional diagram along the middle line AA', please refer to Figure 1 and Figure 22 Optionally, the display panel 100 further includes a transparent encapsulation layer 81 , and the transparent encapsulation layer 81 is located on a side of the first light shielding layer 40 away from the substrate 10 .
[0143] Specifically, a transparent encapsulation layer 81 may be disposed on the side of the first light-shielding layer 40 away from the substrate 10. The transparent encapsulation layer 81 is used to encapsulate and isolate water and oxygen, thereby improving the reliability of the display panel 100. It should be noted that the transparent encapsulation layer 81 is in direct contact with the first light-shielding layer 40 and the barrier layer 50. The transparent encapsulation layer 81 can be made of the same material as the barrier layer 50, thereby reducing the number of materials used in the display panel 100. This is merely an example for illustration and is not intended to be limiting.
[0144] Please refer to continue reference Figure 1 and Figure 22 Regarding the thickness of the transparent encapsulation layer 81, the present disclosure provides an optional embodiment in which the thickness of the transparent encapsulation layer 81 is greater than the thickness of the first light-shielding layer 40. In this way, the transparent encapsulation layer 81 can cover the first light-shielding layer 40 and the display area of the display panel 100, which is further beneficial for isolating water and oxygen and protecting the display panel 100.
[0145] Please refer to continue reference Figure 1 and Figure 22 Optionally, the thickness of the transparent encapsulation layer 81 is H1, and H1>1μm. This setting is beneficial for the transparent encapsulation layer 81 to cover the first light-shielding layer 40 and the display area of the display panel 100, and is more beneficial for improving the reliability of the display panel 100. The present disclosure provides an optional embodiment in which the thickness of the first light-shielding layer 40 is h=1μm, and the thickness of the transparent encapsulation layer 81 is H1=2μm; the present disclosure provides another optional embodiment in which the thickness of the first light-shielding layer 40 is h=2μm, and the thickness of the transparent encapsulation layer 81 is H1=4μm; the present disclosure provides yet another optional embodiment in which the thickness of the first light-shielding layer 40 is h=3μm, and the thickness of the transparent encapsulation layer 81 is H1=4μm. The present disclosure is merely illustrative of this example and is not limited thereto.
[0146] Please refer to continue reference Figure 1 and Figure 22 Optionally, the display panel 100 further includes a transparent adhesive layer 82 and a cover plate 90 , wherein the transparent adhesive layer 82 is located on the side of the transparent encapsulation layer 81 away from the substrate 10 , and the cover plate 90 is located on the side of the transparent adhesive layer 82 away from the substrate 10 , and the transparent adhesive layer 82 is in direct contact with the cover plate 90 .
[0147] Specifically, the display panel 100 further includes a cover plate 90, which is bonded to the side of the transparent encapsulation layer 81 away from the substrate 10 via a transparent adhesive layer 82. The present disclosure provides an optional embodiment in which the transparent adhesive layer 82 includes OCA adhesive (Optically Clear Adhesive). OCA adhesive is an adhesive used for bonding transparent optical elements. It has high transparency, low haze, and good optical properties. It can minimize the refraction, reflection, and scattering of light while bonding optical materials, thereby ensuring the clarity and transmittance of the optical system. The transparent adhesive layer 82 including OCA adhesive is beneficial to improving the display effect of the display panel 100.
[0148] Please refer to continue reference Figure 1 and Figure 22 Optionally, the thickness of the transparent adhesive layer 82 is H2, 50 μm≤H2≤500 μm.
[0149] Specifically, the display panel 100 also includes a driver chip, which is located on one side of the display area of the display panel 100. When the thickness H2 of the transparent adhesive layer 82 is less than 50 μm, the transparent adhesive layer 82 is relatively thin, and the total thickness of the display area of the display panel 100 may be less than the thickness of the driver chip, which is not conducive to adhesion to the cover plate 90. When the thickness H2 of the transparent adhesive layer 82 is greater than 500 μm, the transparent adhesive layer 82 is relatively thick, which is not conducive to thinning the display panel 100. Therefore, the thickness H2 of the transparent adhesive layer 82 is set to 50 μm ≤ H2 ≤ 500 μm. This setting is conducive to both thinning the display panel 100 and adhesion to the cover plate 90. The present disclosure provides an optional implementation manner in which the thickness of the transparent adhesive layer 82 is H2 = 60 μm; the present disclosure provides another optional implementation manner in which the thickness of the transparent adhesive layer 82 is H2 = 66 μm; the present disclosure provides yet another optional implementation manner in which the thickness of the transparent adhesive layer 82 is H2 = 100 μm; the present disclosure provides yet another optional implementation manner in which the thickness of the transparent adhesive layer 82 is 65 μm ≤ H2 ≤ 200 μm; the present disclosure provides yet another optional implementation manner in which the thickness of the transparent adhesive layer 82 is 80 μm ≤ H2 ≤ 400 μm.
[0150] Based on the same inventive concept, the present disclosure provides a display device, Figure 23 FIG2 is a schematic diagram of a display device provided by an embodiment of the present disclosure, please refer to FIG2 Figure 23 The display device 23 includes the display panel 100 provided in an embodiment of the present disclosure.
[0151] It should be noted that the embodiment of the display device 200 provided in the present application can refer to the embodiment of the display panel 100 described above, and will not be repeated here. The display device 200 provided in the present application can be any product or component with a display function, such as a mobile phone, a tablet computer, a television, a touch controller, a laptop computer, a navigation system, or the like.
[0152] It can be seen from the above embodiments that the display panel and display device provided by the present disclosure achieve at least the following beneficial effects:
[0153] The present disclosure provides a display panel and a display device. The display panel includes a substrate, a drive array layer located on one side of the substrate, a light-emitting element located on a side of the drive array layer away from the substrate, and a first light-shielding layer located on a side of the light-emitting element away from the substrate. The present disclosure arranges that the surface of the first light-shielding layer on the side close to the light-emitting element is at a distance greater than zero from the surface of the light-emitting element away from the substrate. That is, the first light-shielding layer does not directly contact the light-emitting element. This facilitates removal of the first light-shielding layer above the light-emitting element, thereby reducing the impact of the first light-shielding layer on the light-emitting element, thereby improving the display effect of the display panel.
