Description

Technical Field

[0001] This application relates to the field of display technology, specifically to display modules and display devices. Background Technology

[0002] Current display panels, such as those based on Organic Light Emitting Diode (OLED) and Light Emitting Diode (LED), offer advantages such as high image quality, energy saving, thinness, and wide applicability. They are widely used in various consumer electronics products, including mobile phones, televisions, laptops, and desktop computers, and have become the mainstream display panels.

[0003] In traditional display panel manufacturing, a fine metal mask (FMM) is typically used to pattern the light-emitting pixels. FMM technology is mature and has extensive mass production experience. However, FMM technology also suffers from limitations in precision, high development costs, and long development cycles. Fine metal mask-less technology eliminates the limitations of traditional OLED processes on display size, resolution, and other screen performance characteristics, offering advantages such as high performance, full-size display, and agile delivery.

[0078] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0079] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods and means well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0080] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0081] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0082] The first aspect of this application provides a display module, as shown in the reference. Figure 1 The schematic diagram of the display module shown, and Figure 2 and Figure 3 The schematic diagram of the isolation structure and touch layer shown indicates that the module includes: a substrate 100, an isolation structure 200, a light-emitting device 300, and a touch layer 400.

[0083] For example, Figure 1 It can be Figure 2 A schematic diagram of the cross-sectional structure along the bb' direction.

[0084] Optionally, refer to Figure 2 and Figure 3 The isolation structure 200 is located on one side of the substrate 100 and encloses a plurality of isolation openings 210. The isolation structure 200 enclosing the isolation openings 210 includes a first isolation portion 211 and a second isolation portion 212. The width L1 of the first isolation portion 211 is greater than the width L2 of the second isolation portion 212.

[0085] For example, the isolation structure 200 can achieve the effect of patterning the light-emitting device without using an FMM. For instance, the isolation structure 200 can isolate the light-emitting functional layer 320 and the second electrode layer 330, thereby enabling the patterning of the light-emitting functional layer 320 and the second electrode layer 330.

[0086] Optionally, at least a portion of the light-emitting device 300 is located in the isolation opening 210.

[0087] Optionally, refer to Figure 1 The light-emitting device 300 includes a first electrode layer 310 located between the isolation structure 200 and the substrate 100, with at least a portion of the first electrode layer 310 exposed in the isolation opening 210.

[0088] Optionally, refer to Figure 1 The light-emitting device also includes a light-emitting functional layer 320 and a second electrode layer 330 located in the isolation opening 210, with the second electrode layer 330 located on the side of the light-emitting functional layer 320 away from the substrate 100.

[0089] Exemplarily, one of the first electrode layer 310 and the second electrode layer 330 is an anode, and the other is a cathode. For example, the first electrode layer 310 can be an anode, and the second electrode layer 330 can be a cathode. The light-emitting functional layer 320 includes an emitting layer (EML), and may further include at least one of a hole injection layer (HIL), a hole transport layer (HTL), and an electron-blocking layer (EBL) located between the anode and the emitting layer (EML), and at least one of an electron injection layer (EIL), an electron transport layer (ETL), and a hole-blocking layer (HBL) located between the cathode and the emitting layer (EML).

[0090] Optionally, the touch layer 400 is located on the side of the isolation structure 200 away from the substrate 100, and encloses a plurality of first openings 410. The orthographic projection of the first opening 410 on the substrate 100 overlaps with the orthographic projection of the isolation opening 210 on the substrate 100. The touch layer 400 includes a first touch portion 401 and a second touch portion 402. The orthographic projection of the first touch portion 401 on the substrate 100 overlaps with the orthographic projection of the first isolation portion 401 on the substrate 100, and the orthographic projection of the second touch portion 402 on the substrate 100 overlaps with the orthographic projection of the second isolation portion 212 on the substrate 100. The width W1 of the first touch portion 401 is greater than the width W2 of the second touch portion 402.

[0091] For example, the touch layer 400 can be a self-capable touch layer or a mutual-capable touch layer. The structure of self-capable touch layers and mutual-capable touch layers can refer to the structure of self-capable touch layers and mutual-capable touch layers in conventional technology, and will not be described in detail here.

[0092] It is understandable that there are multiple light-emitting devices 300, and the arrangement of these multiple light-emitting devices 300 includes, but is not limited to, RGB arrangement, Pentile arrangement, diamond arrangement, Delta arrangement, 2-in-1 arrangement, etc. The spacing between adjacent light-emitting devices 300 is not completely consistent, resulting in the width of the orthographic projection of the isolation structure 200 onto the substrate 100 also not being completely consistent; refer to... Figure 4 The schematic diagram of the top view of the touch layer and the isolation structure shown in the prior art indicates that the width of the orthographic projection of the entire touch layer 400 on the substrate 100 is uniform. This results in the distance between the edge of the orthographic projection of the touch layer 400 on the substrate 100 and the edge of the orthographic projection of the isolation structure 200 on the substrate 100 being inconsistent. In some cases, the touch layer 400 may even block the isolation opening 210, causing color shift in the display module. Furthermore, a light-transmitting hole is provided in the isolation structure 200, and the width of the isolation structure 200 around the light-transmitting hole is smaller. The touch layer 400 may block part of the light-transmitting hole, resulting in low light transmittance of the display module. In this application, the width of the orthographic projection of the isolation structure 200 on the substrate 100 is adaptively adjusted according to the width of the orthographic projection of the touch layer 400 on the substrate 100. For example, according to the display module provided in the embodiment of this application, the width L1 of the first isolation part 211 is greater than the width L2 of the second isolation part 212, and the width W1 of the first touch part 401 corresponding to the first isolation part 211 is greater than the width W2 of the second touch part 402 corresponding to the second isolation part 212. This makes the width of the touch part corresponding to the isolation part with different widths different, which is beneficial to optimize the distance between the edge of the orthographic projection of the first opening 410 on the substrate 100 and the edge of the orthographic projection of the isolation opening 210 on the substrate 100, avoid the risk of color deviation, and enhance the display effect.

[0093] In one embodiment, the orthographic projection of the first touch portion 401 on the substrate 100 is within the orthographic projection range of the first isolation portion 211 on the substrate 100, and the orthographic projection of the second touch portion 402 on the substrate 100 is within the orthographic projection range of the second isolation portion 212 on the substrate 100. Therefore, the first touch portion 401 and the second touch portion 402 have almost no impact on the isolation opening 210 and do not affect light emission.

[0094] Optionally, refer to Figure 5 The top view of the first isolation section and the first touch section shown shows that, along the extending direction a of the first isolation section 401, the distance d1 between the edge of the orthographic projection of the first touch section 401 at different positions on the substrate 100 and the edge of the orthographic projection of the first isolation section 211 on the substrate 100 is the same. This helps to reduce the risk of color shift in the display module.

[0095] Optionally, refer to Figure 6The top view of the second isolation section and the second touch section shown shows that, along the extending direction b of the second isolation section 402, the distance d2 between the edge of the orthographic projection of the second touch section 402 at different positions on the substrate 100 and the edge of the orthographic projection of the second isolation section 212 on the substrate 100 is the same. This helps to reduce the risk of color shift in the display module.

[0096] Optionally, the orthographic projection of the isolation opening 210 on the substrate 100 is located within the orthographic projection range of the first opening 410 on the substrate 100. As a result, the touch layer 400 hardly obstructs the isolation opening 210 and hardly affects the light emission of the light-emitting device.

[0097] Optionally, refer to Figure 7 The schematic diagram of the top view of the isolation opening and the first opening shown shows that, along the circumference of the first opening 410, the distance between the edge of the orthographic projection of the isolation opening 210 on the substrate 100 and the edge of the orthographic projection of the first opening 410 on the substrate 100 are the same. Therefore, along the circumference of the first opening 410, the light emission effect of the light-emitting device is basically consistent, which is more conducive to reducing the risk of color shift in the display module.

[0098] In one embodiment, the ratio of the width W1 of the first touch portion 401 to the width L1 of the first isolation portion 211 is 20% to 90%, for example, it can be 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, etc., and the ratio of the width W2 of the second touch portion 402 to the width L2 of the second isolation portion 212 is 20% to 90%, for example, it can be 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, etc. Therefore, the width W2 of the first touch portion 401 and the second touch portion 402 is suitable, hardly obstructing the isolation opening 210, and making the resistance of the touch layer 400 relatively suitable, resulting in a better touch effect.

[0099] Optionally, the width W1 of the first touch portion 401 is greater than or equal to 3 micrometers and less than or equal to 10 micrometers, for example, it can be 3 micrometers, 4 micrometers, 5 micrometers, 6 micrometers, 7 micrometers, 8 micrometers, 9 micrometers, or 10 micrometers, etc.; the width of the second touch portion is greater than or equal to 2.5 micrometers and less than or equal to 10 micrometers, for example, it can be 2.5 micrometers, 3 micrometers, 4 micrometers, 5 micrometers, 6 micrometers, 7 micrometers, 8 micrometers, 9 micrometers, or 10 micrometers, etc. Therefore, the width W2 of the first touch portion 401 and the second touch portion 402 is suitable, hardly obstructing the isolation opening 210, and making the resistance of the touch layer 400 relatively suitable, resulting in better touch performance.

[0100] In one embodiment, refer to Figure 2The isolation opening 210 includes a first isolation opening 201 and a second isolation opening 202 arranged along a first direction x, and a first isolation portion 211 is located between the first isolation opening 201 and the second isolation opening 202.

[0101] Optionally, the light-emitting device 300 includes a first light-emitting device and a second light-emitting device, wherein the first light-emitting device is located in the first isolation opening 201 and the second light-emitting device is located in the second isolation opening 202.

[0102] For example, the first light-emitting device is a red light-emitting device R, and the second light-emitting device is a blue light-emitting device B.

[0103] In one embodiment, the isolation opening 210 further includes a third isolation opening 203 and a fourth isolation opening 204 arranged along the second direction y. The line connecting the first isolation opening 201 and the second isolation opening 202 along the first direction x is located between the adjacent third isolation opening 203 and fourth isolation opening 204 in the second direction y. The first direction x intersects the second direction y; for example, the first direction x and the second direction y are perpendicular to each other.

[0104] For example, in the first direction x, the line connecting the first isolation opening 201 and the second isolation opening 202 is parallel to, but does not overlap with, the line connecting the third isolation opening 203 and the fourth isolation opening 204. In the second direction y, the line connecting the first isolation opening 201 and the second isolation opening 202 is parallel to, but does not overlap with, the line connecting the third isolation opening 203 and the fourth isolation opening 204.

[0105] Optionally, the light-emitting device 300 also includes a third light-emitting device and a fourth light-emitting device, wherein the third light-emitting device is located in the third isolation opening 203 and the fourth light-emitting device is located in the fourth isolation opening 204.

[0106] For example, both the third and fourth light-emitting devices are green light-emitting devices G.

[0107] For example, in the first direction x, the first isolation opening 201 and the second isolation opening 202 are arranged alternately, and in the second direction y, the first isolation opening 201 and the second isolation opening 202 are arranged alternately. For example, in the first direction x, red light-emitting device R and blue light-emitting device B are arranged alternately, and in the second direction y, red light-emitting device R and blue light-emitting device B are arranged alternately.

[0108] For example, the green light-emitting devices G are arranged along the first direction x and the second direction y.

[0109] For example, the light-emitting device 300 in this embodiment is arranged in a diamond pattern.

[0110] In one embodiment, refer to Figure 2 The isolation structure 200 further includes a first light-transmitting hole 220 located between adjacent first isolation openings 201 and second isolation openings 202; the touch layer 400 also includes a through hole 420, the orthographic projection of the first light-transmitting hole 220 on the substrate 100 being within the orthographic projection range of the through hole 420 on the substrate 100. Therefore, the through hole 420 is relatively large and hardly affects the transmission of light through the first light-transmitting hole 220.

[0111] Optionally, the isolation structure 200 also includes a ninth isolation section 219, which encloses a first light-transmitting hole 220.

[0112] Optionally, the touch layer 400 further includes a third touch portion 403, which surrounds a through hole 420. The width of the third touch portion 403 is smaller than the width W2 of the second touch portion 402. It is understood that in the isolation structure 200, the width of the ninth isolation portion 219 surrounding the first light-transmitting hole 220 is the smallest. If the width of the touch layer 400 corresponding to the ninth isolation portion 219 is the same as the width of the touch layers 400 at other locations, the risk of obstructing the first light-transmitting hole 220 is relatively high. In this application, the width of the third touch portion 403 is smaller than the width W2 of the second touch portion 402. The relatively smaller width of the third touch portion 403 helps reduce the risk of the touch layer 400 obstructing the first light-transmitting hole 220, resulting in a relatively high light transmittance of the display module.

[0113] It should be noted that the first light-transmitting hole 220 and the through hole 420 can be used to transmit ambient light, which helps to improve the touch accuracy of the display module, or to improve the contrast of the display module under ambient light, thereby improving the display quality of the display module in different usage environments.

[0114] Optionally, in the orthographic projection of the isolation structure 200 onto the substrate 100, the width of the ninth isolation portion 219 is smaller than the width L1 of the first isolation portion 211 and the width L2 of the second isolation portion 212; in the orthographic projection of the touch layer 400 onto the substrate 100, the width of the third touch portion 403 is smaller than the width W1 of the first touch portion 401 and the width W2 of the second touch portion 402. In the isolation structure 200, the width of the ninth isolation portion 219 surrounding the first light-transmitting hole 220 is smaller, and the corresponding width of the third touch portion 403 is smaller, which is beneficial to improving the light transmittance of the display module and improving the performance of the display module.

[0115] In one embodiment, the isolation opening 210 includes a first isolation opening 201, and the isolation structure 200 surrounding the first isolation opening 201 further includes a third isolation portion 213 and a fourth isolation portion 214. The third isolation portion 213 is disposed opposite to the first isolation portion 211, and the fourth isolation portion 214 is disposed opposite to the second isolation portion 212. The width of the third isolation portion 213 is less than the width L1 of the first isolation portion 211, and the width L2 of the fourth isolation portion 214 is equal to that of the second isolation portion 212. Alternatively, the widths of the first isolation portion 211, the second isolation portion 212, the third isolation portion 213, and the fourth isolation portion 214 are not equal, and the width L1 of the first isolation portion 211 is greater than the widths of the second isolation portion 212, the third isolation portion 213, and the fourth isolation portion 214. Along the circumferential direction of the first isolation opening 201, the distance between the edge of the orthographic projection of the first isolation opening 201 on the substrate 100 and the edge of the orthographic projection of the corresponding first opening 410 on the substrate 100 is the same. Therefore, the widths of the first isolation portion 211, the second isolation portion 212, the third isolation portion 213, and the fourth isolation portion 214 of the isolation structure 200 that encloses the first isolation opening 201 may be the same or different. When the distance between the edge of the orthographic projection of the first isolation opening 201 on the substrate 100 and the edge of the orthographic projection of the corresponding first opening 410 on the substrate 100 is consistent along the circumference of the first isolation opening 201, the width of the touch layer 400 around the first isolation opening 201 can be made to be basically consistent with the width distribution pattern of the isolation structure 200, which helps to reduce the risk of color deviation of the display module and hardly affects the light emission effect of the light-emitting device 300.

[0116] For example, the orthographic projection of the first isolation opening 210 onto the substrate 100 is a quadrilateral.

[0117] Optionally, the isolation structure that encloses the isolation opening further includes a fifth isolation section 215, a sixth isolation section 216, a seventh isolation section 217, and an eighth isolation section 218. The widths of the fifth isolation section 215, the sixth isolation section 216, the seventh isolation section 217, and the eighth isolation section 218 are all smaller than the width L1 of the first isolation section 211. The fifth isolation section 215 and the sixth isolation section 216 are arranged opposite each other, and the seventh isolation section 217 and the eighth isolation section 218 are arranged opposite each other. The first isolation section 211, the second isolation section 212, the seventh isolation section 217, the sixth isolation section 216, the third isolation section 213, the fourth isolation section 214, the eighth isolation section 218, and the fifth isolation section 215 are connected end to end in sequence.

[0118] For example, the orthographic projection of the first isolation opening 210 onto the substrate 100 is octagonal. Among the first isolation portions 211 to the eighth isolation portions 218 that enclose the first isolation opening 210, the widths of adjacent isolation portions are not equal, while the widths of two oppositely arranged isolation portions are equal. Specifically, the width L1 of the first isolation portion 211 is not equal to the width of the third isolation portion 213. Alternatively, the widths of adjacent isolation portions are equal, while the widths of two oppositely arranged isolation portions are not equal. Specifically, the widths L2 of the second isolation portion 212 and the fifth isolation portion 215 are both smaller than the width L1 of the first isolation portion 211; or, all isolation portions have unequal widths. Along the circumference of the first isolation opening 201, the distance between the edge of the orthographic projection of the first isolation opening 201 onto the substrate 100 and the edge of the orthographic projection of the corresponding first opening 410 onto the substrate 100 is the same. Therefore, the width of the isolation structure 200 that encloses the first isolation opening 201 may be partially the same or different. When the distance between the edge of the orthographic projection of the first isolation opening 201 on the substrate 100 and the edge of the orthographic projection of the corresponding first opening 410 on the substrate 100 is consistent along the circumference of the first isolation opening 201, the width of the touch layer 400 around the first isolation opening 201 can be basically consistent with the width distribution pattern of the isolation structure 200, which helps to reduce the risk of color deviation of the display module and hardly affects the light emission effect of the light-emitting device 300.

[0119] In one embodiment, refer to Figure 1 The display module also includes an encapsulation layer 500, located on the side of the touch layer 400 near the isolation structure 200.

[0120] For example, refer to Figure 8 The schematic diagram of the display panel shown illustrates that the encapsulation layer 500 includes a first encapsulation layer 510, which in turn includes multiple encapsulation portions 511. These encapsulation portions 511 are located on the side of the light-emitting device 300 and the isolation structure 200 facing away from the substrate 100, and are correspondingly positioned with the isolation opening 210. Therefore, the encapsulation effect of the encapsulation portions 511 is excellent, which helps protect the light-emitting device 300 from damage by the etching solution during the fabrication process.

[0121] For example, the encapsulation layer 500 further includes a second encapsulation layer 520 and a third encapsulation layer 530, with the third encapsulation layer 530 located on the side of the second encapsulation layer 520 opposite to the first encapsulation layer 510. For instance, the first encapsulation layer 510 and the third encapsulation layer 530 are both inorganic encapsulation layers, and the second encapsulation layer 520 is an organic encapsulation layer. The first encapsulation layer 510 and the third encapsulation layer 530 can be prepared by chemical vapor deposition (CVD), and the second encapsulation layer 520 can be prepared by inkjet printing (IJP).

[0122] It is understandable that in the process of preparing the display module, the encapsulation layer 500 is prepared first, and then the encapsulation layer 500 is prepared on the side of the encapsulation layer 500 that is away from the substrate 100.

[0123] In one embodiment, refer to Figure 1 The display module also includes a pixel defining layer 600, located on the side of the isolation structure 200 near the substrate 100, which encloses a plurality of pixel openings 610; the orthographic projection of the pixel openings 610 on the substrate 100 is within the orthographic projection range of the isolation openings 210 on the substrate 100.

[0124] Optionally, the pixel defining layer 600 includes a first pixel defining portion 601 and a second pixel defining portion 602. The orthographic projection of the first isolation portion 211 on the substrate 100 is located within the orthographic projection range of the first pixel defining portion 601 on the substrate 100, and the orthographic projection of the second isolation portion 212 on the substrate 100 is located within the orthographic projection range of the second pixel defining portion 602 on the substrate 100. The width of the first pixel defining portion 601 is greater than the width of the second pixel defining portion 602.

[0125] Optionally, refer to Figure 9 and Figure 10 The schematic cross-sectional view of the isolation structure shown illustrates that the isolation structure 200 includes a first part 230 and a second part 240 stacked together. The first part 230 is located on the side of the second part 240 facing away from the substrate 100, and the orthographic projection of the second part 240 onto the substrate 100 lies within the orthographic projection range of the first part 230 onto the substrate 100. For example, the second part 240 can be designed as an independent film layer, meaning there is no physical interface within the second part 240, and all parts are made of the same material, such as aluminum. Alternatively, the second part 240 can be designed as being composed of at least two stacked film layers. For example, the second part 240 can be formed by stacking two conductive film layers. The materials of these two conductive film layers can be molybdenum and aluminum, respectively, and the conductive film layer made of molybdenum is located between the substrate 100 and the conductive film layer made of aluminum. For example, the second part 240 may include a conductive sub-part, or the second part 240 itself may be a conductive structure. The second part 240 overlaps with the second electrode layer 330 of the light-emitting device 300, so that the second electrode layers 330 of adjacent light-emitting devices 300 are electrically connected to each other, thereby realizing a full-surface cathode. The material of the first part 230 can be an organic material, an inorganic material, or a metallic material. When the first part 230 is a metallic material, the material of the first part 230 can be titanium.

[0126] In one embodiment, refer to Figure 11The schematic cross-sectional view of the isolation structure shown includes a third part 250 located on the side of the second part 240 near the substrate 100. The orthographic projection of the second part 240 onto the substrate 100 falls within the orthographic projection range of the third part 250 onto the substrate 100. For example, the second part 240 is a conductive film layer made of aluminum, and the third part 250 is a conductive film layer made of molybdenum. In this case, the cross-section of the isolation structure 200 is I-shaped. For example, the third part 250 overlaps with the second electrode layer 330 of the light-emitting device 300, so that the second electrode layers 330 of adjacent light-emitting devices 300 are electrically connected to each other, thereby achieving a full-surface cathode.

[0127] For example, refer to Figure 12 The schematic diagram of the cross-sectional structure of the display module shown can be... Figure 2 The cross section along the aa' direction. The orthogonal projection of the through hole 420 on the substrate 100 covers the orthogonal projection of the first light-transmitting hole 220 on the substrate 100.

[0128] Exemplarily, substrate 100 may be a substrate substrate. In some embodiments, the substrate substrate may be a glass substrate. In some embodiments, the substrate substrate may include organic resin materials such as epoxy resin, triazine, silicone resin, or polyimide. For example, the substrate substrate may be an FR4 type printed circuit board (PCB), or it may be a flexible PCB that is easily deformable. In some embodiments, the substrate substrate may include ceramic materials such as silicon nitride, aluminum nitride, or aluminum oxide, or it may include metals or metal compounds. For example, the substrate substrate may be a metal core PCB (MCPCB) or a metal copper clad laminate (MCCL).

The orthographic projection of the first opening 410 on the substrate 100 overlaps with the orthographic projection of the pixel opening 610 on the substrate 100. The touch layer 400 includes a first touch portion 401 and a second touch portion 402. The orthographic projection of the first touch portion 401 on the substrate 100 overlaps with the orthographic projection of the first pixel defining portion 601 on the substrate 100, and the orthographic projection of the second touch portion 402 on the substrate 100 overlaps with the orthographic projection of the second pixel defining portion 602 on the substrate 100. The width W1 of the first touch portion 401 is greater than the width W2 of the second touch portion 402.

[0133] It should be noted that the first touch unit 401 and the second touch unit 402 are consistent with the previous description, and will not be repeated here.

[0137] In one embodiment, the orthographic projection of the pixel opening 610 on the substrate 100 is located within the orthographic projection range of the first opening 410 on the substrate 100.

[0138] For example, refer to Figure 17 The top view of the pixel opening and the first opening shown in the diagram shows that, along the circumference of the first opening 410, the distance between the orthographic projection of the pixel opening 610 on the substrate 100 and the edge of the orthographic projection of the first opening 410 on the substrate 100 is the same.

[0139] In one embodiment, the ratio of the width W1 of the first touch portion 401 to the width L1 of the first isolation portion 211 is 20% to 90%, for example, it can be 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, etc., and the ratio of the width W2 of the second touch portion 402 to the width L2 of the second isolation portion 212 is 20% to 90%, for example, it can be 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, etc. Therefore, the width W2 of the first touch portion 401 and the second touch portion 402 is suitable, hardly obstructing the pixel opening 610, and making the resistance of the touch layer 400 relatively suitable, resulting in a better touch effect.

[0140] In one embodiment, the pixel opening 610 includes a first pixel opening 611 and a second pixel opening 612, and the pixel defining layer 600 further includes a second light-transmitting hole 620 located between adjacent first pixel openings 611 and second pixel openings 612; the touch layer 400 further includes a through hole 420, and the orthographic projection of the second light-transmitting hole 620 on the substrate 100 is located within the orthographic projection range of the through hole 420 on the substrate 100.
