[0023] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.

[0025] See Figure 1 , Figure 1 1 is a schematic structural diagram of an embodiment of a display panel of the present application. The display panel 100 includes a substrate 110 , a pixel definition layer 120 , a light-emitting element 130 , an isolation structure 140 , a functional layer 150 and a reflector 160 .

[0026] The substrate 110 plays a supporting role in the display panel 100, wherein the substrate 110 also includes structures such as a pixel circuit for driving the light-emitting element 130 to emit light, wherein the pixel circuit can specifically be a 7T1C circuit, which is not limited in this application.

[0027] The pixel definition layer 120 is disposed on one side of the substrate 110 and has a plurality of first openings 121. Specifically, the pixel definition layer 120 can be formed of an organic material such as polyimide (PI), polyamide, benzocyclobutene (BCB), acrylic resin, or phenolic resin, or an inorganic material such as silicon nitride, or the pixel definition layer 120 can include both organic and inorganic materials. In one embodiment, the pixel definition layer 120 includes a light-absorbing material to absorb ambient light and reduce the reflectivity of the display panel 100.

[0028] The isolation structure 140 is arranged on the side of the pixel definition layer 120 away from the substrate 110, and the isolation structure 140 is provided with a plurality of second openings 1401. The orthographic projections of the first opening 121 and the second opening 1401 on the substrate 110 at least partially overlap, that is, the first opening 121 and the second opening 1401 are connected.

[0029] The light-emitting element 130 is disposed in the first opening 121 and the second opening 1401. The light-emitting element 130 includes a first electrode 131, a light-emitting material layer 132, and a second electrode 133, disposed sequentially in a direction away from the substrate 110. One of the first electrode 131 and the second electrode 133 serves as an anode, and the other serves as a cathode. For ease of description, the following description assumes that the first electrode 131 serves as the anode and the second electrode 133 serves as the cathode. There are multiple light-emitting elements 130, some emitting red light, some emitting green light, and some emitting blue light.

[0030] A light absorption structure 180 is provided on the surface of the isolation structure 140 facing away from the substrate 110. Figure 1 As shown, due to the provision of the light absorption structure 180 , the ambient light incident on the isolation structure 140 will be directly absorbed by the light absorption structure 180 , thereby enabling the display panel 100 to absorb the ambient light and reducing the reflectivity of the display panel 100 .

[0031] Functional layer 150 is disposed on the side of isolation structure 140 facing away from substrate 110. Functional layer 150 includes a light absorbing member 152. The orthographic projection of light absorbing member 152 on substrate 110 at least partially does not overlap with the orthographic projection of light emitting element 130 on substrate 110. Specifically, light absorbing member 152 absorbs light, thereby preventing light leakage from display panel 100. Furthermore, the orthographic projection of light absorbing member 152 on substrate 110 does not overlap at all, or only partially overlaps with the orthographic projection of light emitting element 130 on substrate 110, thereby preventing interference with normal illumination of display panel 100.

[0032] The reflector 160 is disposed on the surface of the isolation structure 140 facing the functional layer 150 and is used to reflect external light so that the reflected external light is directed toward the light absorbing member 152. Figure 1 As shown, when the external ambient light is directed toward the interior of the display panel 100, the light that hits the reflector 160 is reflected by the reflector 160 and then directed toward the light absorbing member 152, thereby being absorbed by the light absorbing member 152, thereby realizing the display panel 100's absorption of the external ambient light and reducing the reflectivity.

[0033] That is to say, in the above embodiment, on the one hand, a light-absorbing structure 180 is provided on the surface of the isolation structure 140 facing away from the substrate 110, so that the external ambient light incident on the isolation structure 140 will be directly absorbed by the light-absorbing structure 180, thereby reducing the reflectivity of the display panel 100; on the other hand, a reflective element 160 is provided to reflect external light, so that the reflected external light is directed toward the light-absorbing element 152, thereby being absorbed by the light-absorbing element 152, which can also reduce the reflectivity of the display panel 100.

[0034] It should be noted that, in other embodiments, only the reflector 160 may be provided without the light absorbing structure 180. Figure 2 Alternatively, only the light absorbing structure 180 may be provided without the reflective element 160, as shown in FIG. Figure 3 shown.

[0035] In one embodiment, see Figure 1 as well as Figure 3 A groove 1402 is provided on the surface of the isolation structure 140 facing away from the substrate 110, and the light absorption structure 180 is provided in the groove 1402, thereby reducing the thickness of the display panel 100. During the preparation process, the isolation structure 140 can be prepared first, and then the isolation structure 140 is grooved to obtain the groove 1402. Then, the groove 1402 is filled with a light absorption material to obtain the light absorption structure 180. The light absorption material can be filled in the groove 1402 by an inkjet printing process, or by a deposition process using a mask.

[0036] Of course, in other embodiments, the isolation structure 140 may not be provided with the groove 1024 , and its surface may be a flat surface, and the light absorption structure 180 may be directly provided on the surface of the isolation structure 140 facing away from the substrate 110 .

[0037] Among them Figure 1 As shown, in order to reflect the light toward the light absorbing element 152 , the surface of the reflector 160 facing away from the substrate 110 is inclined relative to the substrate 110 , that is, the surface of the reflector 160 facing away from the substrate 110 is an inclined surface.

[0038] Continue reading Figure 1 The functional layer 150 also includes a plurality of filter blocks 154, and the plurality of filter blocks 154 are arranged in a one-to-one correspondence with the plurality of light-emitting elements 130. The filter blocks 154 are arranged in the light-emitting direction of the corresponding light-emitting element 130, and the light-absorbing element 152 is arranged between two adjacent filter blocks 154. Specifically, the filter blocks 154 only allow the light emitted by the corresponding light-emitting element 130 to be transmitted. For example, when the light-emitting element 130 emits red light, the corresponding filter block 154 only transmits red light. When the light-emitting element 130 emits green light, the corresponding filter block 154 only transmits green light, and so on. By setting the filter blocks 154, it is no longer necessary to set a polarizer for the display panel 100. Of course, in other embodiments, the display panel 100 may further include a polarizer. In this case, the polarizer can be located on the side of the functional layer 150 facing away from the substrate 110.

[0039] Combine Figure 4 The reflective element 160 includes a reflective carrier 162 and a reflective layer 164 . The reflective carrier 162 has an inclined surface facing away from the substrate 110 , and the reflective layer 164 is disposed on the inclined surface of the reflective carrier 162 . At this time, the reflective layer 164 is used to reflect light toward the light absorbing element 152 .

[0040] The material of the reflective carrier 162 includes at least one of an inorganic material and an organic material. Specifically, the material of the reflective carrier 162 may include only inorganic materials, only organic materials, or both inorganic and organic materials. The inorganic material may include at least one of silicon nitride, silicon oxide, and zirconium oxide, and the organic material may include at least one of acrylic materials, epoxy materials, and silicone materials, without limitation.

[0041] The reflective layer 164 may be a metal layer, and the material of the metal layer includes at least one of titanium, aluminum, molybdenum, copper, iron, and gold. That is, a metal film layer is deposited on the surface of the reflective carrier 162 facing away from the substrate 110 to obtain the reflective layer 164.

[0042] Alternatively, the reflective layer 164 includes reflective particles, that is, reflective particles are deposited on the surface of the reflective carrier 162 facing away from the substrate 110 to form the reflective layer 164. The reflective particles can be metal particles or particles of any material, which is not limited here.

[0043] Continue reading Figure 2 The display panel 100 further includes a first encapsulation layer 171 , a second encapsulation layer 172 and a third encapsulation layer 173 .

[0044] The first encapsulation layer 171 is disposed on the side of the light-emitting element 130 facing away from the substrate 110. The orthographic projection of the first encapsulation layer 171 on the substrate 110 covers the orthographic projection of the light-emitting element 130 on the substrate 110. The first encapsulation layer 171 extends onto a portion of the surface of the isolation structure 140, and at least the portion of the first encapsulation layer 171 extending onto the isolation structure 140 forms a reflective carrier 162. Specifically, the first encapsulation layer 171 is used to encapsulate the light-emitting element 130 to prevent external moisture from invading the light-emitting element 130. The first encapsulation layer 171 is partially disposed on the light-emitting element 130 and partially disposed on the isolation structure 140. The first encapsulation layer 171 disposed on the isolation structure 140 is used as the reflective carrier 162, eliminating the need to use other processes to prepare the reflective carrier 162, thereby improving preparation efficiency.

[0045] The second encapsulation layer 172 is disposed on the side of the first encapsulation layer 171 facing away from the substrate 110, wherein the orthographic projection of the second encapsulation layer 172 on the substrate 110 covers the orthographic projections of the light-emitting element 130 and the isolation structure 140 on the substrate 110. The third encapsulation layer 173 is disposed on the side of the second encapsulation layer 172 facing away from the substrate 110. Specifically, the provision of the second encapsulation layer 172 and the third encapsulation layer 173 can further ensure the encapsulation effect of the display panel 100 and further prevent the intrusion of external moisture. It should be noted that in other embodiments, the second encapsulation layer 172 and the third encapsulation layer 173 may not be provided.

[0046] In one embodiment, the materials of the first encapsulation layer 171 and the third encapsulation layer 173 both comprise inorganic materials, and the materials of the second encapsulation layer 172 both comprise organic materials. Specifically, the inorganic film layer-organic film layer-inorganic film layer encapsulation structure can further improve the encapsulation effect of the display panel 100. It should be noted that this application does not impose any restrictions on the materials of the first encapsulation layer 171, the second encapsulation layer 172, and the third encapsulation layer 173, and can be selected based on actual needs.

[0047] The functional layer 150 is located on a side of the third encapsulation layer 173 facing away from the substrate 110 .

[0048] In other embodiments, the reflective carrier 162 may also be independent of the first encapsulation layer 171 , that is, the reflective carrier 162 and the first encapsulation layer 171 are two independent structures.

[0049] In another embodiment, the reflector 160 is made of a metal material, and the metal material is directly used to reflect light. To reduce the difficulty of manufacturing and improve the manufacturing effect, the isolation structure 140 is reused as the reflector 160, that is, the reflector 160 and the isolation structure 140 are integrally formed. That is, the reflector 160 and the isolation structure 140 are integrally formed, and the isolation structure 140 is also made of a metal material, so that the reflector 160 and the isolation structure 140 can be simultaneously manufactured in a single process. In this case, the material of the reflector 160 can include at least one of titanium, aluminum, molybdenum, copper, iron, and gold, and this application does not impose any restrictions on this.

[0050] Of course, when the reflective element 160 is made of metal, the reflective element 160 can also be independent of the isolation structure 140 .

[0051] Continue reading Figure 1 In order to prevent the reflector 160 from affecting the light absorption structure 180 absorbing light, the orthographic projection of the reflector 160 on the substrate 110 and the orthographic projection of the light absorption structure 180 on the substrate 110 are arranged at an interval.

[0052] In one embodiment, the light absorbing element 152 has the same structure as the light absorbing structure 180, and the orthographic projection of the light absorbing element 152 on the substrate 110 coincides with the orthographic projection of the light absorbing structure 180 on the substrate 110, that is, the shape and size of the light absorbing element 152 and the light absorbing structure 180 are the same, so that the mask plate used to prepare the light absorbing structure 180 and the mask plate used to prepare the light absorbing element 152 can be the same mask plate, thereby reducing production costs.

[0053] The specific size of the light absorption structure 180 can be set according to various factors such as the requirements for adjusting the viewing angle and the requirements for brightness attenuation.

[0054] To reduce the number of materials used in the manufacturing process and lower production costs, the light absorbing element 152 and the light absorbing structure 180 are made of the same material. Of course, in other embodiments, the light absorbing element 152 and the light absorbing structure 180 may also be made of different materials, which can be selected based on specific needs and is not limited here.

[0055] The light absorbing element 152 and the light absorbing structure 180 may be made of black light absorbing material, and this application does not impose any limitation on the specific material.

[0056] In one embodiment, a light absorption structure 180 is disposed around the periphery of the green light emitting element 130 , the red light emitting element 130 , and the blue light emitting element 130 .

[0057] For ease of explanation, the first opening 121 where the green light-emitting element 130 is located is defined as a pixel definition opening 121A, the first opening 121 where the red light-emitting element 130 is located is defined as a pixel definition opening 121B, and the first opening 121 where the blue light-emitting element 130 is located is defined as a pixel definition opening 121C. In a direction parallel to the substrate 110, the distance between the pixel definition opening 121A and the adjacent light absorption structure 180 is a first distance, the distance between the pixel definition opening 121B and the adjacent light absorption structure 180 is a second distance, and the distance between the pixel definition opening 121C and the adjacent light absorption structure 180 is a third distance. In one application scenario, The first distance is greater than the second distance, and the second distance is greater than the third distance. When the orthographic projection of the light absorbing element 152 on the substrate 110 coincides with the orthographic projection of the light absorbing structure 180 on the substrate 110, in a direction parallel to the substrate 110, the distance between the pixel defining opening 121A and the light absorbing element 152 corresponding to the adjacent light absorbing structure 180 is the fourth distance, the distance between the pixel defining opening 121B and the light absorbing element 152 corresponding to the adjacent light absorbing structure 180 is the fifth distance, and the distance between the pixel defining opening 121C and the light absorbing element 152 corresponding to the adjacent light absorbing structure 180 is the sixth distance. At this time, the fourth distance is greater than the fifth distance, and the fifth distance is greater than the sixth distance. The above setting is set in consideration of the degree of influence of ambient light on the green light-emitting element 130, the red light-emitting element 130, and the blue light-emitting element 130. However, in different application scenarios, the size settings between the above distances can be adjusted according to actual needs and are not limited here.

[0058] In one embodiment, the second electrode 133 of the light-emitting element 130 is electrically connected to the isolation structure 140. Specifically, in the related art, when the second electrodes 133 of all light-emitting elements 130 are continuous and uninterrupted, that is, the second electrode 133 is a whole film layer (for ease of explanation, the whole film layer is defined as the second electrode layer), due to the presence of resistance, the potential at different positions of the second electrode layer is different, and thus the potential of the second electrodes 133 in different light-emitting elements 130 is different, which ultimately affects the luminous efficiency of the light-emitting element 130. Therefore, to avoid this defect, the isolation structure 140 is provided in this embodiment to be electrically connected to the second electrode 133 of the light-emitting element 130. Applying a voltage (negative voltage) to the second electrode 133 through the isolation structure 140 can reduce the voltage drop and ensure the luminous efficiency of the light-emitting element 130.

[0059] In order to prevent the groove 1402 from affecting the electrical connection between the isolation structure 140 and the second electrode 133, the groove 1402 is set as a blind groove, that is, the groove 1402 does not penetrate the isolation structure 140 in the thickness direction of the display panel 100, and the depth of the groove 1402 is less than the thickness of the isolation structure 140, thereby ensuring the transmission impedance of the isolation structure 140 and ensuring the electrical connection between the isolation structure 140 and the second electrode 133.

[0060] Continue reading Figures 1 to 3 In order to reduce transmission impedance and ensure electrical connection between the isolation structure 140 and the second electrode 133 , the thickness of the isolation structure 140 is greater than the thickness of the second electrode 133 .

[0061] Among them, such as 1 to Figure 3 As shown, the second electrode 133 extends from the first opening 121 to the sidewall of the isolation structure 140 , thereby achieving electrical connection with the isolation structure 140 .

[0062] Combine Figure 3 as well as Figure 5 The isolation structure 140 includes a first isolation layer 141 and a second isolation layer 142 stacked in sequence in a direction away from the substrate 110. The orthographic projection of the second isolation layer 142 on the substrate 110 covers the orthographic projection of the first isolation layer 141 on the substrate 110, and the orthographic projection of the second isolation layer 142 on the substrate 110 extends beyond the orthographic projection of the first isolation layer 141 on the substrate 110. In other words, the first isolation layer 141 is retracted relative to the second isolation layer 142, so that the end of the isolation structure 140 away from the substrate 110 has a structure similar to an eave. This structure can ensure that when the light-emitting material layer 132 in the light-emitting element 130 is deposited, the light-emitting material layer 132 is disconnected at the isolation structure 140, which can ensure that the light-emitting material layers 132 in the light-emitting elements 130 with different luminous colors are discontinuous, thereby reducing the difficulty of preparation and ensuring product yield. At the same time, the provision of the first isolation layer 141 and the second isolation layer 142 can also reduce the resistance of the isolation structure 140.

[0063] In order to further reduce the transmission resistance of the isolation structure 140 , the isolation structure 140 further includes a third isolation layer 143 located between the first isolation layer 141 and the substrate 110 .

[0064] In one embodiment, the material of the first isolation layer 141 includes aluminum, the material of the second isolation layer 142 includes titanium, and the material of the third isolation layer 143 includes molybdenum. The combination of molybdenum layer-aluminum layer-titanium layer can ensure that the impedance of the isolation structure 140 is minimized, and the titanium layer can also protect the aluminum layer to prevent the aluminum layer from being etched.

[0065] Continue reading Figure 3The second electrode 133 extends to the sidewalls of the third isolation layer 143 and the first isolation layer 141 , thereby achieving electrical connection between the second electrode 133 and the isolation structure 140 .

[0066] In order to ensure the climbing effect of the second electrode 133, the contact between the second electrode 133 and the first isolation layer 141 is ensured. Figure 5 As shown, the cross-sections of the first isolation layer 141 and the third isolation layer 143 perpendicular to the substrate 110 are regular trapezoids. Of course, in other embodiments, the cross-sections of the first isolation layer 141 and the third isolation layer 143 perpendicular to the substrate 110 may also be rectangular, triangular, or other shapes, which are not limited here.

[0067] In one embodiment, in order to reduce the difficulty of preparation, Figure 5 As shown, the groove 1402 penetrates the second isolation layer 142 and extends into the first isolation layer 141. In one embodiment, the groove 1402 further penetrates the first isolation layer 141 and communicates with the third isolation layer 143. At this time, the third isolation layer 143 is exposed in the groove 1402.

[0068] In one embodiment, if Figure 5 As shown, the light-absorbing structure 180 includes a first sub-light-absorbing element 181 disposed in the first isolation layer 141 and a second sub-light-absorbing element 182 disposed in the second isolation layer 142, wherein the orthographic projection of the first sub-light-absorbing element 181 on the substrate 110 overlaps the orthographic projection of the second sub-light-absorbing element 182 on the substrate 110. Specifically, during the manufacturing process, after forming the first isolation layer 141, a groove is formed in the first isolation layer 141, and then a light-absorbing material is formed in the groove to obtain the first sub-light-absorbing element 181. Then, the second isolation layer 142 is formed on the first isolation layer 141, and then a groove is formed in the second isolation layer 142 to expose a portion of the first sub-light-absorbing element 181. The groove is then filled with light-absorbing material to obtain the second sub-light-absorbing element 182. In other words, the light-absorbing structure 180 is manufactured in a step-by-step manner.

[0069] In order to reduce the difficulty of groove formation, the width of the grooves formed on the first isolation layer 141 and the second isolation layer 142 increases in the direction away from the substrate 110, so that Figure 4 As shown, the cross-section of the first sub-light absorbing element 181 perpendicular to the substrate 110 is an inverted trapezoid, and the cross-section of the second sub-light absorbing element 182 perpendicular to the substrate 110 is an inverted trapezoid. It should be noted that in other embodiments, the cross-section of the first sub-light absorbing element 181 perpendicular to the substrate 110 may also be a regular trapezoid or rectangle, or other shapes, and the cross-section of the second sub-light absorbing element 182 perpendicular to the substrate 110 may also be a regular trapezoid or rectangle, or other shapes. This application does not limit the shapes of the first sub-light absorbing element 181 and the second sub-light absorbing element 182.

[0070] See Figure 6 In another embodiment, after the entire isolation structure 140 is prepared, grooves are cut and then filled with light absorbing material to obtain the light absorbing structure 180. At this time, the light absorbing structure 180 is an integral structure formed in one process. Figure 6 In an embodiment, a cross section of the light absorption structure 180 perpendicular to the substrate 110 is in an inverted trapezoidal shape.

[0071] In one embodiment, if Figure 7 As shown, the isolation structure 140 includes a plurality of sub-isolation structures 1403 , which are spaced apart and insulated. The light emitting elements 130 electrically connected to the same sub-isolation structure 1403 emit the same light color.

[0072] Specifically, the light-emitting elements 130 electrically connected to the same sub-isolation structure 1403 emit the same color. This ensures that the voltage applied to the second electrode 133 of the light-emitting elements 130 of the same color is the same, ensuring that the light-emitting elements 130 of the same color emit the same brightness. Light-emitting elements 130 emitting different colors are electrically connected to different sub-isolation structures 1403. This allows different voltages to be applied to the second electrodes 133 of the light-emitting elements 130 of different colors, thereby reducing power consumption.

[0073] For example Figure 7 As shown, the sub-isolation structure 1403 is a strip-shaped structure. The light-emitting elements 130 in the same column and emitting red light are electrically connected to one sub-isolation structure 1403. The light-emitting elements 130 in the same column and emitting green light are electrically connected to another sub-isolation structure 1403. The light-emitting elements 130 in the same column and emitting blue light are electrically connected to yet another sub-isolation structure 1403. In other embodiments, the isolation structure 140 may be a monolithic structure. In this case, the isolation structure 140 may be a mesh-shaped structure. Details are described below.

[0074] See Figure 8The display panel 100 includes a display area AA and a non-display area NA. The display area AA includes an opening area A1 and a main screen area A2 arranged outside the opening area A1. Specifically, the display area AA is used to display images and is usually provided with structures such as a driving circuit and a light-emitting element 130. The non-display area NA does not emit light and is usually provided with structures such as peripheral circuits. It can also be used to bond driver chips or bonding circuit boards (such as flexible circuit boards FPC). In the display area AA, the opening area A1 needs to allow external light to pass through, so that devices such as cameras, light sensors, and earpieces can be placed in the opening area A1. Among them, the substrate 110, the pixel definition layer 120, the light-emitting element 130, and the isolation structure 140 are all partially located in the opening area A1 and partially located in the main screen area A2. In other words, the substrate 110, the pixel definition layer 120, the light-emitting element 130, and the isolation structure 140 are all provided in the opening area A1 and the main screen area A2.

[0075] Among them, considering that the opening area A1 needs to allow external light to pass through, this embodiment ensures that sufficient light passes through the opening area A1, and the reflector 160 is only set on the surface of the isolation structure 140 located in the main screen area A2, and the reflector 160 is not set on the surface of the isolation structure 140 located in the opening area A1. That is, only the main screen area A2 includes the reflector 160, and the opening area A1 does not include the reflector 160.

[0076] Similarly, in order to ensure that sufficient light passes through the opening area A1, this embodiment only grooves the isolation structure 140 located in the main screen area A2, so that the light absorption structure 180 is only set in the main screen area A2, and no light absorption structure 180 is set in the opening area A1. Figures 9 to 12 , Figure 9 is a schematic diagram of the relative positions of the light emitting element 130 and the isolation structure 140 in the opening area A1. Figure 10 is a schematic top view of the isolation structure 140 in the opening area A1. Figure 11 Schematic diagram of the relative positions of the light emitting element 130, the isolation structure 140 and the light absorbing structure 180 in the main screen area A2. Figure 12 This is a schematic diagram of the relative positions of the isolation structure 140 and the light absorption structure 180 in the main screen area A2. Figures 9 to 12 It can be seen that at this time, the light absorption structure 180 is not provided in the opening area A1 , and the light absorption structure 180 is only provided in the main screen area A2 .

[0077] Combined with Figure 11 as well as Figure 12 In one embodiment, the light absorption structure 180 is a block structure, and to ensure sufficient absorption of ambient light, multiple light absorption structures 180 are disposed around the periphery of the light emitting element 130. In other embodiments, only one light absorption structure 180 may be disposed around the periphery of the light emitting element 130.

[0078] In one embodiment, if Figure 13 As shown, when the isolation structure 140 is in a grid structure, the light absorption structure 180 may also be in a grid structure.

[0079] In contrast to the grid-like structure of the light absorption structure 180, the light absorption structure 180 is configured as a block structure. The density of the light absorption structure 180 can be adjusted as needed. For example, when the light absorption structure 180 is in a block shape, one, two, or three light absorption structures 180 can be provided around the periphery of the light-emitting element 130, depending on the density setting. In one embodiment, some of the light absorption structures 180 can be in a block structure, while others can be in a grid structure.

[0080] Continue reading Figure 2 The display panel 100 further includes a touch layer 191 , which is located between the functional layer 150 and the isolation structure 140 , and further between the functional layer 150 and the third encapsulation layer 173 . An insulating layer 192 is also included between the touch layer 191 and the third encapsulation layer 173 .

[0081] It should also be noted that the display panel 100 of the present application can be an OLED display panel (Liquid Crystal Display, organic light-emitting diode display panel), and the liquid crystal display panel can also be an LCD display panel (Liquid Crystal Display, liquid crystal display panel), a Mirco-LED display panel (Micro Light Emitting Diode, micro light-emitting diode display panel) and other types of display panels.
