Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display device and electronic device. Background Technology

[0002] In related technologies, display devices use a metal layer in the non-display area for wiring, serving as a means of electrical conduction. Simultaneously, the display device uses ink to shield the screen frame at the edge of the cover plate, preventing glare and light leakage from the metal wiring. Because the actual positions of the ink screen printing and cover plate bonding are affected by process precision, a certain gap must be left between the inner edge of the ink and the edge of the display area to ensure the ink does not obscure the display area. This gap becomes a reflective emission area. When the display panel is exposed to ambient light, the metal layer in the non-display area will strongly reflect light. The unobstructed portion of the reflected light from the metal layer will escape through this gap, creating glare and affecting the viewing experience. Summary of the Invention

[0051] In related technologies, display devices use a metal layer in the non-display area for wiring, serving as a means of electrical conduction. Simultaneously, the display device uses ink to shield the screen frame at the edge of the cover plate, preventing glare and light leakage from the metal wiring. Because the actual positions of the ink screen printing and cover plate bonding are affected by process precision, a certain gap must be left between the inner edge of the ink and the edge of the display area to ensure the ink does not obscure the display area. This gap becomes a reflective emission area. When the display panel is exposed to ambient light, the metal layer in the non-display area will strongly reflect light. The unobstructed portion of the reflected light from the metal layer will escape through this gap, creating glare and affecting the viewing experience.

[0052] To reduce glare in non-display areas of a display device, this application provides a display device in which a light-shielding layer assembly is added between the cover plate and the metal layer, which can reduce glare in non-display areas and improve the user experience. The structure of the display device provided in this application and the principle of reducing glare in non-display areas are explained in detail below with reference to the accompanying drawings.

[0053] Please see Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the display device provided in this application. The display device 10 includes a display panel 100, a metal layer 200, a cover plate 300, and a light-shielding layer group 400. The display panel 100 includes a driving substrate 110 and a light-emitting layer 120. The display panel 100 defines a display area AA and a non-display area NA. The light-emitting layer 120 is located in the display area AA and includes an anode 121, an organic material layer 122, and a cathode 123 sequentially stacked in a direction away from the driving substrate 110. The metal layer 200 is located in the non-display area NA and is disposed in the same layer as the anode 121 and is made of the same material. The cover plate 300 is located on one side of the display panel 100 and on the side of the light-emitting layer 120 away from the driving substrate 110. The cover plate 300 has an ink layer 310. The orthographic projection of the ink layer 310 on the driving substrate 110 is located within the non-display area NA; the light-shielding layer group 400 is located between the metal layer 200 and the cover plate 300, the orthographic projection of the light-shielding layer group 400 on the driving substrate 110 is located within the non-display area NA and the light-shielding layer group 400 covers at least a portion of the metal layer 200, and the light-shielding layer group 400 has at least one light-shielding layer; wherein, the direction from the edge of the display device 10 to the center of the display device 10 is defined as the radial direction Y of the display device 10, the metal layer 200 has an inner edge 201 facing the display area AA, the ink layer 310 has an inner ink edge 311 facing the display area AA, and the light-shielding layer group 400 has an inner light-shielding edge 401 facing the display area AA, the inner light-shielding edge 401 being closer to the display area AA than the inner ink edge 311.

[0054] The display panel 100, as a functional component with display function in the display device 10, includes a driving substrate 110 and a light-emitting layer 120. The light-emitting layer 120 is used to emit light, and the driving substrate 110 is used to provide power to the light-emitting layer 120 to drive the light-emitting layer 120 to emit light and to provide support for other components of the display panel 100.

[0055] Specifically, the driving substrate 110 can be a TFT (Thin Film Transistor) substrate, and the driving substrate 110 includes a substrate and a driving circuit disposed on the substrate. The substrate can be formed of a rigid material or a flexible material. For example, rigid materials include one of rigid glass, silicon substrate, germanium substrate, and silicon-coated insulating substrate; flexible materials include one of polyethylene naphthalate, polyethylene terephthalate, polyimide, and flexible glass. The driving circuit can be, for example, a 7T1C circuit.

[0056] The light-emitting layer 120 includes an anode 121, an organic material layer 122, and a cathode 123 sequentially stacked in the direction away from the driving substrate 110. The sequentially stacked anode 121, organic material layer 122, and cathode 123 constitute multiple light-emitting devices in the light-emitting layer 120. Each light-emitting device is composed of an anode 121, an organic material layer 122, and a cathode 123. The organic material layer 122 is configured to emit light, such as red (R), green (G), blue (B), or other colors of light, when the anode 121 and cathode 123 are energized. Each light-emitting device emits monochromatic light under the drive of the driving circuit of the driving substrate 110. That is, the light-emitting device can be an OLED (Organic Light-Emitting Diode) light-emitting device, or other light-emitting devices suitable for the inventive concept of this application, without specific limitations. This application uses an OLED light-emitting device as an example to illustrate beneficial effects, but this does not constitute a limitation on this application. OLED light-emitting devices may also include one or more of a hole injection layer, a hole transport layer, a hole blocking layer, an electron transport layer, and an electron injection layer, without being specifically limited here.

[0057] Furthermore, the light-emitting device can be an AMOLED (Active-matrix organic light-emitting diode) light-emitting device.

[0058] Typically, the light-emitting layer 120 also includes a pixel definition layer, which has multiple pixel openings, within which light-emitting devices are disposed. The pixel definition layer acts as a partition structure between the multiple light-emitting devices, defining the position of each device, ensuring isolation between them, and preventing crosstalk. The material of the pixel definition layer can include organic materials, such as imide, PMMA photoresist, polyimide photoresist, and silicone photoresist. The material of the pixel definition layer can also include inorganic materials, such as silica aqueous solution systems or silanol solution systems, etc., without specific limitations.

[0059] In some embodiments, the display panel 100 further includes an encapsulation substrate 130 for encapsulating the various light-emitting devices of the display panel 100. The encapsulation substrate 130 may be a glass substrate. The driving substrate 110, the light-emitting layer 120, and the encapsulation substrate 130 constitute the main structure of the display panel 100. In some embodiments, the display panel 100 may also exclude the encapsulation substrate 130 and instead use the cover plate 300 directly as the encapsulation structure of the display panel 100.

[0060] The display area AA and the non-display area NA of the display panel 100 refer to the fact that the display area AA is the screen light-emitting area that can be directly observed by the naked eye, while the non-display area NA is the screen area that is difficult to see directly from the edge of the screen. The aforementioned light-emitting layer 120 is provided in the display area AA, while the light-emitting layer 120 is not provided in the non-display area NA. Therefore, the display panel 100 only has light-emitting and display functions in the display area AA.

[0061] It should be noted that, since this application is for reducing the reflection of the non-display area NA of the display device 10, that is, for the structural design of the non-display area NA, therefore... Figure 1 The diagram primarily shows the structure of the non-display area NA. Only a portion of the display area AA's structure is shown; the overall structure of the display area AA is not fully represented. Figure 1 This is a schematic diagram of the structure of the display device 10, and does not limit the entire structure of its display area AA.

[0062] The metal layer 200 serves as the trace for the non-display area NA, providing electrical conduction. The metal layer 200 is disposed on the same layer as the anode 121 of the display panel 100 and is made of the same material. For example, both the metal layer 200 and the anode 121 can be made of, but are not limited to, silver (Ag). Silver has low impedance (i.e., low resistance value), which is mainly used in the traces to reduce signal loss and interference during transmission, ensuring stable signal transmission. Simultaneously, the silver-based metal layer 200 also has high reflectivity. When the display panel 100 is exposed to ambient light, especially under strong ambient light, the metal layer 200 of the non-display area NA will strongly reflect the ambient light.

[0063] The cover plate 300 serves as the outermost protective structure of the display device 10, protecting the display panel 100 and other structures of the display device 10. The ink layer 310 on the cover plate 300 is used to block reflections from the non-display area NA of the display device 10. Specifically, it is used to block reflected light generated by the metal layer 200 reflecting ambient light, thereby reducing reflections from the display device 10 in the non-display area NA. The ink layer 310 can be formed on the cover plate 300 using processes such as screen printing. Because the actual position of the ink screen printing and the cover plate 300 bonding is affected by process precision, a certain gap (typically 0.15–0.2 mm) is required between the inner edge 311 of the ink and the display area AA to ensure that the ink layer 310 does not block the display area AA. This gap will become a reflective emission area. In conventional process capabilities, the ink screen printing precision is ±150 μm, and the cover plate 300 bonding precision is ±100 μm. In extreme cases, the gap may widen to approximately 0.45 mm, significantly reducing the light-blocking effect.

[0064] The light-shielding layer group 400 serves as a supplementary structure to the ink layer 310 on the cover plate 300 to prevent reflections in the non-display area NA. It is used to further reduce the reflections of the display device 10 in the non-display area NA. The light-shielding layer group 400 is located between the metal layer 200 and the cover plate 300. The orthographic projection of the light-shielding layer group 400 on the driving substrate 110 is located within the non-display area NA and covers at least a portion of the metal layer 200. At the same time, the light-shielding inner edge 401 of the light-shielding layer group 400 is closer to the display area AA than the ink inner edge 311 of the ink layer 310. Therefore, the light-shielding layer group 400 located inside the ink layer 310 can block some ambient light from entering the surface of the metal layer 200 and prevent the ambient light from being reflected by the surface of the metal layer 200, thereby reducing the reflections of ambient light on the metal layer 200, which is to reduce the reflection problem of the display device 10 in the non-display area NA.

[0065] As can be seen, the display device 10 provided in this application has a light-shielding layer group 400 between the metal layer 200 and the cover plate 300, and the light-shielding inner edge 401 of the light-shielding layer group 400 is located on the side of the ink inner edge 311 of the ink layer 310 of the cover plate 300 near the display area AA. The light-shielding layer group 400 located inside the ink layer 310 can block some ambient light from entering the surface of the metal layer 200 and prevent the ambient light from being reflected by the surface of the metal layer 200, thereby reducing the reflection of ambient light on the metal layer 200, that is, reducing the reflection problem of the display device 10 in the non-display area NA.

[0066] Please see Figure 2 , Figure 2This is a schematic diagram of the structure of an embodiment of the display device 10 provided in this application. In some embodiments, the display device 10 further includes a touch layer 500, which is located between the light-emitting layer 120 and the cover plate 300. The touch layer 500 includes peripheral signal lines 510. The orthographic projection of the peripheral signal lines 510 on the display panel 100 is located in the non-display area NA. The peripheral signal lines 510 have an inner edge 511 of the peripheral signal lines facing the display area AA. The inner edge 511 of the peripheral signal lines is closer to the display area AA than the inner edge 311 of the ink.

[0067] The light-shielding layer group 400 includes a first light-shielding layer 410 disposed on the touch layer 500. The first light-shielding layer 410 is located on the side of the touch layer 500 facing the cover plate 300. The first light-shielding layer 410 has a first light-shielding inner edge 411 facing the display area AA. The light-shielding inner edge 401 is the first light-shielding inner edge 411.

[0068] The touch layer 500 is used to realize the touch function of the display device 10, and the peripheral signal lines 510 on the touch layer 500 are used to conduct electrical communications to the touch layer 500. The peripheral signal lines 510 are located near the edge / periphery of the touch layer 500, and the material of the peripheral signal lines 510 can be a molybdenum alloy or a titanium-aluminum-titanium composite film.

[0069] In this embodiment, the light-shielding layer group 400 includes a first light-shielding layer 410, which is disposed on the touch layer 500. The first light-shielding layer 410 can block some ambient light from entering the surface of the metal layer 200 and prevent the ambient light from being reflected by the surface of the metal layer 200, thereby reducing the reflection of ambient light on the metal layer 200 (this reflection can also be called strong reflection), which reduces the reflection problem of the display device 10 in the non-display area NA. In addition, the first light-shielding layer 410 can also block the peripheral signal lines 510 of the touch layer 500, thereby reducing the reflection of ambient light on the peripheral signal lines 510 (this reflection can also be called weak reflection).

[0070] In some embodiments, the first light-shielding layer 410 further has a first light-shielding outer edge 412 facing away from the display area AA. When facing upward from the display device 10, the distance between the first light-shielding outer edge 412 and the display area AA is greater than or the same as the distance between the ink inner edge 311 and the display area AA. Figure 2 This shows that the distance between the outer edge 412 of the first light-shielding layer and the display area AA is greater than the distance between the inner edge 311 of the ink layer and the display area AA. This means that the ink layer 310 can block a portion of the first light-shielding layer 410 while exposing another portion. In other words, the orthographic projection of the ink layer 310 on the driving substrate 110 overlaps with the orthographic projection of the first light-shielding layer 410 on the driving substrate 110. Please refer to... Figure 3 , Figure 3 This is a schematic diagram of the structure of an embodiment of the display device 10 provided in this application. Figure 3 The diagram shows that the distance between the first light-shielding outer edge 412 and the display area AA is the same as the distance between the ink inner edge 311 and the display area AA, meaning the first light-shielding layer 410 is completely located on the side of the ink layer 310 facing the display area AA. In other embodiments, it is possible that the distance between the first light-shielding outer edge 412 and the display area AA is less than the distance between the ink inner edge 311 and the display area AA. It is understood that when the distance between the first light-shielding outer edge 412 and the display area AA is greater than the distance between the ink inner edge 311 and the display area AA, it can be ensured that after the cover plate 300 and the touch layer 500 are assembled, even if there are assembly errors in the cover plate 300 and the touch layer 500, the first light-shielding layer 410 can still block the area inside the ink layer 310 in the radial Y direction of the display device 10, preventing gaps between the cover plate 300 and the first light-shielding layer 410 in the radial Y direction of the display device 10 from affecting the light-shielding effect of the first light-shielding layer 410.

[0071] In some embodiments, in the radial Y direction of the display device 10, the distance between the first light-shielding inner edge 411 and the display area AA is greater than or the same as the distance between the outer signal line inner edge 511 and the display area AA. Figure 2 and Figure 3 This illustrates the case where the distance between the inner edge 411 of the first light-shielding layer and the display area AA is the same as the distance between the inner edge 511 of the peripheral signal line and the display area AA. The inner edge 411 of the first light-shielding layer extends toward the display area AA on the touch layer 500 without exceeding the peripheral signal line 510, meaning that the first light-shielding layer only partially covers or completely covers the peripheral signal line 510 of the touch layer 500.

[0072] In some embodiments, in the radial Y direction of the display device 10, the distance between the first light-shielding inner edge 411 and the display area AA is less than the distance between the outer peripheral signal line inner edge 511 and the display area AA. That is, the first light-shielding inner edge 411 extends beyond the outer peripheral signal line 510 on the touch layer 500 toward the display area AA, which can better ensure that the first light-shielding completely blocks the outer peripheral signal line 510 of the touch layer 500.

[0073] However, it is understandable that since the first light-shielding layer 410 is formed directly on the touch layer 500, it is easy to control the relative position between the first light-shielding layer 410 and the peripheral signal lines 510. As long as the first light-shielding layer 410 completely blocks the portion of the peripheral signal lines 510 not blocked by the ink layer 310, weak reflection of the peripheral signal lines 510 by the first light-shielding layer 410 can be achieved. Therefore, the relative position between the first light-shielding layer 410 and the peripheral signal lines 510 can be preferably as follows: Figure 2The distance between the first light-shielding inner edge 411 and the display area AA is the same as the distance between the inner edge 511 of the peripheral signal line and the display area AA. This ensures that the first light-shielding layer 410 completely blocks the peripheral signal line 510 of the touch layer 500. The relative positional relationship between the first light-shielding outer edge 412 and the ink inner edge 311 is affected by the assembly precision of the cover plate 300. Therefore, the preferred relative positional relationship between the first light-shielding outer edge 412 and the ink inner edge 311 is that the distance between the first light-shielding outer edge 412 and the display area AA is greater than the distance between the ink inner edge 311 and the display area AA. More preferably, it is as follows: Figure 2 The first light-shielding outer edge 412 shown extends toward the outer edge of the peripheral signal line 510 in a direction away from the display area AA.

[0074] In some embodiments, continue reading Figure 2 The display panel 100 also includes an encapsulation substrate 130, which is located between the light-emitting layer 120 and the cover plate 300. The touch layer 500 is disposed on the encapsulation substrate 130 and is located on the side of the encapsulation substrate 130 facing the cover plate 300. For details on the structure of the encapsulation substrate 130, please refer to the aforementioned embodiments.

[0075] In some embodiments, continue reading Figure 2 The display device 10 also includes a polarizing layer 600 disposed on the encapsulation substrate 130. The polarizing layer 600 is located on the side of the encapsulation substrate 130 facing the cover plate 300. The polarizing layer 600 is used to block the light reflected by the light-emitting layer 120. The touch layer 500 is disposed on the side of the polarizing layer 600 facing the cover plate 300.

[0076] For OLED displays, the polarizing layer 600 effectively filters and manages light, improving contrast and making the light emitted by the OLED display more orderly and pure. When ambient light shines on the OLED screen, it passes through the encapsulation substrate 130 and reaches the metal cathode 123. The metal cathode 123, like a silver reflective foil, reflects the ambient light back. This results in a significant decrease in display quality and contrast of the OLED screen under strong ambient light, such as outdoor sunlight, making the screen difficult to see. Therefore, the OLED screen needs a polarizing layer 600 to block reflected light. The polarizing layer 600 can be formed on the encapsulation substrate 130 or it can be a separate polarizer. Figure 2 This illustrates the case where a polarizing layer 600 is formed on a packaging substrate 130.

[0077] Please see Figure 4 , Figure 4This is a schematic diagram of the structure of an embodiment of the display device 10 provided in this application. In some embodiments, the light-shielding layer group 400 includes a second light-shielding layer 420, which covers the side of the metal layer 200 facing the cover plate 300. The second light-shielding layer 420 has a second light-shielding inner edge 421 facing the display area AA, and the light-shielding inner edge 401 is the second light-shielding inner edge 421.

[0078] In this embodiment, the light-shielding layer group 400 includes a second light-shielding layer 420. The light-shielding layer group 400 is directly disposed on the metal layer 200, which makes it easier to control the light-shielding distance L. Compared with the aforementioned solution of disposing the light-shielding layer group 400 on the touch layer 500, since the touch layer 500 is disposed on the packaging substrate 130, the alignment accuracy between the packaging substrate 130 and the driving substrate 110 during installation will cause a positional deviation of the light-shielding layer group 400, resulting in an error in the light-shielding distance L. However, in this embodiment, the light-shielding layer group 400 is directly disposed on the metal layer 200, which can eliminate the positional deviation of the light-shielding layer group 400 caused by the alignment accuracy between the packaging substrate 130 and the driving substrate 110. Therefore, it is more conducive to controlling the light-shielding distance L.

[0079] However, it is understandable that in this embodiment, since the light-shielding layer group 400 is disposed on the metal layer 200, compared with the solution where the light-shielding layer group 400 is disposed on the touch layer 500, it loses the blocking effect of the light-shielding layer group 400 on the peripheral signal line 510 of the touch layer 500, and therefore loses the blocking effect on the weak reflection of the peripheral signal line 510.

[0080] In some embodiments, the second light-shielding layer 420 further has a second light-shielding outer edge 422 facing away from the display area AA. In the radial Y direction, the distance between the second light-shielding outer edge 422 and the display area AA is greater than or the same as the distance between the ink inner edge 311 and the display area AA.

[0081] In some embodiments, the inner edge 201 of the metal layer is closer to the display area AA than the second light-shielding inner edge 421. That is, the second light-shielding inner edge 421 does not extend completely to the inner edge 201 of the metal layer, which can reduce the impact of the second light-shielding layer 420 on the display area AA. Figure 4 This illustrates a scenario where the inner edge 201 of the metal layer is closer to the display area AA than the second inner edge 421 of the light-shielding layer. In other embodiments, the distance between the inner edge 201 of the metal layer and the display area AA in the radial Y direction of the display device 10 may also be the same as the distance between the second inner edge 421 of the light-shielding layer and the display area AA.

[0082] In some embodiments, the display panel 100 further includes an encapsulation substrate 130, which is located between the light-emitting layer 120 and the cover plate 300. For details regarding the structure of the encapsulation substrate 130, please refer to the foregoing embodiments.

[0083] In some embodiments, the display device 10 further includes a polarizing layer 600 disposed on the encapsulation substrate 130. The polarizing layer 600 is located on the side of the encapsulation substrate 130 facing the cover plate 300, and the polarizing layer 600 is used to block the light reflected by the light-emitting layer 120. For details on the structure of the polarizing layer 600, please refer to the foregoing embodiments.

[0084] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of an embodiment of the display device 10 provided in this application. In some embodiments, when the light-shielding layer group 400 includes a second light-shielding layer 420 disposed on the metal layer 200, the display device 10 also includes a touch layer 500, which is located on the side of the polarizing layer 600 facing the cover plate 300.

[0085] In this embodiment, the touch layer 500 is used to implement the touch function of the display device 10. In other embodiments, the display device 10 may not include the touch layer 500, that is, the display device 10 does not have touch function.

[0086] In some embodiments, the touch layer 500 covers the polarizing layer 600. In other embodiments, it is not excluded that the touch layer 500 may be disposed in other locations.

[0087] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of an embodiment of the display device 10 provided in this application. In some embodiments, the light-shielding layer group 400 includes a first light-shielding layer 410 and a second light-shielding layer 420. The first light-shielding layer 410 is located between the second light-shielding layer 420 and the cover plate 300. The first light-shielding layer 410 has a first light-shielding inner edge 411 facing the display area AA. The second light-shielding layer 420 has a second light-shielding inner edge 421 facing the display area AA. The second light-shielding layer 420 is closer to the display area AA than the first light-shielding inner edge 411. The light-shielding inner edge 401 is the second light-shielding inner edge 421.

[0088] In this embodiment, the light-shielding layer group 400 includes both a first light-shielding layer 410 and a second light-shielding layer 420. That is, the light-shielding layer group 400 is composed of at least two light-shielding layers, which can also block some ambient light from entering the surface of the metal layer 200 and prevent the ambient light from being reflected by the surface of the metal layer 200, thereby reducing the reflection of ambient light on the metal layer 200, which reduces the reflection problem of the display device 10 in the non-display area NA.

[0089] In other embodiments, the light-shielding layer group 400 may also be three, four or more light-shielding layers.

[0090] In some embodiments, the first light-shielding layer 410 and the second light-shielding layer 420 may be made of the same material, such as, but not limited to, black materials like organic black glue. In other embodiments, the first light-shielding layer 410 and the second light-shielding layer 420 may be made of different materials.

[0091] Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of an embodiment of the display device 10 provided in this application. In some embodiments, when the light-shielding layer group 400 includes both a first light-shielding layer 410 and a second light-shielding layer 420, the display device 10 also includes a touch layer 500. The touch layer 500 is located between the metal layer 200 and the cover plate 300. The touch layer 500 includes peripheral signal lines 510. The orthographic projection of the peripheral signal lines 510 on the display panel 100 is located within the non-display area NA. The peripheral signal lines 510 have an inner edge 511 of the peripheral signal lines facing the display area AA. The inner edge 511 of the peripheral signal lines is closer to the display area AA than the inner edge 311 of the ink.

[0092] The first light-shielding layer 410 is disposed on the touch layer 500, and the first light-shielding layer 410 is located on the side of the touch layer 500 facing the cover plate 300. The second light-shielding layer 420 is disposed on the metal layer 200, and the second light-shielding layer 420 is located on the side of the metal layer 200 facing the cover plate 300.

[0093] In this embodiment, a first light-shielding layer 410 is disposed on the touch layer 500, and a second light-shielding layer 420 is disposed on the metal layer 200. The first light-shielding layer 410 can block the weak reflection of ambient light by the peripheral signal lines 510 of the touch layer 500, while the second light-shielding layer 420 can block the strong reflection of the area of ​​the metal layer 200 not blocked by the first light-shielding layer 410, thereby further reducing the reflection of the non-display area NA.

[0094] In some embodiments, the second light-shielding layer 420 further has a second light-shielding outer edge 422 facing away from the display area AA. In the radial Y direction, the distance between the second light-shielding outer edge 422 and the display area AA is greater than or the same as the distance between the first light-shielding inner edge 411 and the display area AA.

[0095] Figure 4 and Figure 5 This illustrates a situation where the distance between the second light-shielding outer edge 422 and the display area AA is greater than the distance between the first light-shielding inner edge 411 and the display area AA.

[0096] In some embodiments, the light transmittance of the first light-shielding layer 410 and the second light-shielding layer 420 may be the same or different. The light transmittance of the first light-shielding layer 410 and the second light-shielding layer 420 may both be set to be close to zero, that is, the first light-shielding layer 410 and the second light-shielding layer 420 are completely opaque.

[0097] In some embodiments, the distance between the inner edge 401 of the light-shielding layer and the inner edge 201 of the metal layer in the radial Y direction is defined as the light-shielding distance L, which is less than or equal to a preset distance.

[0098] In this embodiment, the distance between the inner edge 401 of the light-shielding device and the inner edge 201 of the metal layer in the radial Y direction of the display device 10 is defined as the light-shielding distance L. The light-shielding distance L is set to be less than or equal to a preset distance. By controlling the distance between the inner edge 401 of the light-shielding device and the inner edge 201 of the metal layer, the predetermined effect of reducing reflection can be achieved.

[0099] In some embodiments, the preset distance is 14 micrometers. That is, the light-shielding distance L is less than or equal to 14 micrometers. For example, the light-shielding distance L is 5 micrometers, 6 micrometers, 7 micrometers, 8 micrometers, 9 micrometers, 10 micrometers, 11 micrometers, 12 micrometers, 13 micrometers or 14 micrometers. Generally speaking, when the light-shielding distance L is less than 14 micrometers, the reflection of the metal layer 200 that is visible to the naked eye under normal use conditions can be avoided.

[0100] In some embodiments, the light-shielding distance L is 14 micrometers. Since a light-shielding distance L less than or equal to 14 micrometers can avoid the reflection of the metal layer 200 that is visible to the naked eye under normal use, the light-shielding distance L can be set to a maximum value of 14 micrometers. In other embodiments, the light-shielding distance L can also be set to a smaller value, which can also achieve the same effect of avoiding the reflection of the metal layer 200 that is visible to the naked eye under normal use.

[0101] In some embodiments, the distance between the inner edge 311 of the ink and the display area AA in the radial Y direction of the display device 10 is 0.15 mm to 0.45 mm, for example, it can be 0.15 mm, 0.2 mm, 0.25 mm, 0.3 mm, 0.35 mm, 0.4 mm, or 0.45 mm. Limiting the distance between the inner edge 311 of the ink and the display area AA to this specific range can reduce the risk of the ink layer 310 obscuring the display area AA due to the ink screen printing of the cover plate 300 and the actual position of the cover plate 300 being affected by the process precision.

[0102] In some embodiments, the distance between the inner edge 311 of the ink and the display area AA is 0.15mm to 0.2mm. For example, it can be 0.15mm, 0.16mm, 0.17mm, 0.18mm, 0.19mm, or 0.2mm.

[0103] In some embodiments, the inner edge 201 of the metal layer and the anode 121 are spaced apart in the radial Y direction of the display device 10. Since the metal layer 200 is used for the wiring of the non-display area NA, while the anode 121 is used for the light emission of the light-emitting layer 120 of the display area AA, the functions of the metal layer 200 and the anode 121 are different. In this embodiment, the inner edge 201 of the metal layer and the anode 121 are spaced apart in the radial Y direction of the display device 10, which can avoid the adverse effects caused by electrical conduction between the metal layer 201 and the anode 121.

[0104] In some embodiments, the metal layer 200 and the anode 121 are formed together on the driving substrate 110. In this embodiment, the metal layer 200 and the anode 121 are formed together on the driving substrate 110 during manufacturing, which can improve the production efficiency of the display device 10. In other embodiments, the metal layer 200 and the anode 121 may also be formed separately on the driving substrate 110.

[0105] In some embodiments, at least one light-shielding layer in the light-shielding layer group 400 is made of a non-metallic black material. Using a non-metallic black material for the light-shielding layer can improve its light-shielding effect.

[0106] In some embodiments, at least one light-shielding layer in the light-shielding layer assembly 400 is made of organic black adhesive. Organic black adhesive is a high-performance structural adhesive with good light-shielding effect, high adhesion, high temperature resistance, and chemical corrosion resistance.

[0107] In some embodiments, the light reflectivity of the peripheral signal line 510 is less than that of the metal layer 200. In this embodiment, since the light reflectivity of the peripheral signal line 510 is less than that of the metal layer 200, the peripheral signal line 510 also has a certain effect of reducing the reflectivity of the metal layer 200. However, its ability to reduce reflectivity is limited, and ambient light will still be reflected to a certain extent at the peripheral signal line 510, which is the weak reflection mentioned above.

[0108] In some embodiments, the metal layer 200 is made of silver. In other embodiments, the metal layer 200 may also be made of a low-resistance metal other than silver.
