1 / 31 DISPLAY PANEL AND ELECTRONIC DEVICE TECHNICAL FIELD

[001] This disclosure relates to the field of display technologies and, in particular, relates to a display panel and an electronic device. BACKGROUND

[002] With the development of display technologies, state-of-the-art display devices are designed for a high screen-to-body ratio to achieve a full screen. Perforated screen design is one of the methods to increase the screen-to-body ratio. During the perforated screen production process, laser cutting (O-CUT) is required in a display area, and organic luminescent materials at the edges of a cut channel are easy to become a transport channel for external water and oxygen. Special structures usually need to be arranged in the cut edge area to interrupt the connection of organic materials and block the path of water vapor invasion in order to improve the reliability of encapsulation in the cut edge area. However, in a high temperature and humidity reliability test environment, the K element in the perforated screen polarizer can dissolve in water.When the perforated screen is in a display state, a cathode in the cut edge area is in a charged state. The existing electric field can cause K+ to migrate to the encapsulation layer and undergo electrochemical reactions with the silicon oxide in the encapsulation layer. These electrochemical reactions can cause the encapsulation layer to expand and deform, leading to encapsulation failure. SUMMARY

[0028] The following description of each embodiment, with reference to the accompanying drawings, is used to exemplify a specific embodiment that can be realized in this disclosure. The directional terms mentioned in this disclosure, such as top, bottom, front, back, left, right, inside, outside, side, etc., are used only with reference to the orientations of the accompanying drawings.

In the accompanying drawings, the thickness of some layers and areas is exaggerated for greater clarity and ease of description. That is, the size and thickness of each component shown in the accompanying drawings are arbitrary, but this disclosure is not limited to that.

[0029] In response to the problem of encapsulation failure in a cut area of ​​a perforated screen of the prior art, the Petition 870250108819, dated 11 / 27 / 2025, page 16 / 49 9 / 31 The inventor of the present disclosure discovered in his research that, in a high temperature and high humidity reliability test environment, the K element of a polarizer in the perforated screen's cut area can dissolve in water to form potassium hydroxide (KOH). When the perforated screen is in a display state, a cathode may be in a charged state due to its electrical connection to a cathode in the display area. An electric field formed by the charged cathode can cause K+ to migrate to a encapsulation layer and undergo an electrochemical reaction with the silicon oxide (SiOx) of the encapsulation layer. The electrochemical reaction can cause the encapsulation layer to expand and deform, leading to encapsulation failure.

[0030] To solve the above problem, a display panel and an electronic device are provided by this disclosure.

[0031] With reference to FIGS. 1 to 5, FIG. 1 is a top schematic view of a display panel provided in an embodiment of the present disclosure.

With reference to FIG. 1, display panel 100 includes a functional area HA, a display area AA adjacent to the functional area HA, and a transition area TA located between the functional area HA and the display area AA.

[0032] The display area AA is used to display images, and the functional area HA can be located anywhere on the display panel 100, for example, the functional area HA can be located in a central or edge area of ​​the display panel 100. The functional area HA is provided with a hole. Petition 870250108819, dated 11 / 27 / 2025, page 17 / 49 10 / 31 through hole that passes through multiple layers of the 100 display panel film. Functional components such as a headphone jack, a camera, and various sensors can be placed inside the through hole to perform functions such as under-display camera and under-display fingerprint sensor, thus increasing the screen-to-body ratio of the 100 display panel.

[0033] The transition area TA is located between the functional area HA and the display area AA. The transition area TA is configured to accommodate various signal connection lines to transfer signal lines blocked by the functional area HA, such as data lines, source lines, etc. The transition area TA is further configured to provide an encapsulation structure to avoid affecting the encapsulation effectiveness of display panel 100 due to the arrangement of functional area HA. ​​When functional area HA is located in the central area of ​​display panel 100, the transition area TA surrounds functional area HA. ​​When functional area HA is located in the edge area of ​​display panel 100, the transition area TA partially surrounds functional area HA.

[0034] Specifically, referring to FIG. 2, the display panel 100 further includes a substrate 10 and an inorganic insulation layer 20, a first metallic layer 30, an organic insulation layer 40, a light-emitting layer 50 and a first electrode layer 60 arranged sequentially on the substrate 10.

[0035] The inorganic insulation layer 20 is arranged on one side of the substrate 10. The first metallic layer 30 is arranged on the side of the inorganic insulation layer 20, away from the substrate 10; the first metallic layer 30 includes at least one metallic barrier portion 301 arranged in the transition area TA, and at least one side of the metallic barrier portion 301 is provided with a disconnection structure 300. The organic insulation layer 40 is arranged on one side of the first layer.

[0036] With reference to FIG. 3, the light-emitting layer 50 is arranged on one side of the organic insulation layer 40, away from the substrate 10, the light-emitting layer 50 covers the display area AA and extends to the transition area TA, and the light-emitting layer 50 is disconnected at the disconnection structure 300 of the metallic barrier part 301. The first electrode layer 60 is arranged on one side of the light-emitting layer 50, away from the substrate 10, and covers the display area AA and extends to the transition area TA. The first electrode layer 60 is disconnected at the disconnect structure 300 from the metallic barrier part 301. A first electrode layer 60, located on one side of the metallic barrier part 301, is electrically connected to the metallic barrier part 301, and a first electrode layer 60, located on the other side of the metallic barrier part 301, is insulated from the metallic barrier part 301 through the insulating part 401.

[0037] In one embodiment, referring to FIGS. 2 and 3, the first metallic layer 30 includes a plurality of metallic barrier parts 301 arranged in the transition area TA. At least one side of the metallic barrier part 301 is provided with a disconnect structure 300, and the other side of the metallic barrier part 301 is covered by the corresponding insulation part 401. Specifically, one side of at least one of the metallic barrier parts 301 near the display area AA is provided with a disconnect structure 300, and another side of one of the metallic barrier parts 301 near the functional area HA is covered by the corresponding insulation part 401. The metallic barrier part 301 is electrically connected to a first electrode layer 60 near the display area. Petition 870250108819, dated 11 / 27 / 2025, p. 19 / 49 12 / 31 AA in the disconnect structure 300, and the metallic barrier part 301 is insulated with the first electrode layer 60 close to the functional area HA through the insulation part 401.

[0038] In this embodiment, when coating the insulation part 401 on one side of the metal barrier part 301, when the first electrode layer 60 is disconnected at the disconnection structure 300 of the metal barrier part 301, a first electrode layer 60 located on one side of the metal barrier part 301 is electrically connected to the metal barrier part 301, and a first electrode layer 60 located on the other side of the metal barrier part 301 is insulated with the metal barrier part 301 through the insulation part 401.Therefore, the first electrode layer 60 near the HA functional area is isolated from the first electrode layer 60 in the AA display area, and the first electrode layer 60 near the HA functional area may not form an electric field, thus preventing K+ migration in the polarizer to the encapsulation layer and electrochemical reactions, and solving the encapsulation failure problem in the cut area of ​​the perforated screen of the prior art.

[0039] A film layer structure of the display panel 100 and a principle that the first electrode layer 60 located in the TA transition area may not form an electric field are explained in detail below.

A plurality of metal barrier parts 301 are disposed in the second subarea SA2. The organic insulation layer 40 includes at least one insulation part 401 covering one side of the metal barrier part 301 Petition 870250108819, dated 11 / 27 / 2025, p. 20 / 49 13 / 31 corresponding, the insulation parts 401 are arranged in the first subarea SA1 and / or the second subarea SA2. Optionally, the number of insulation parts 401 is less than or equal to the number of metal barrier parts 301. In this way, one insulation part 401 can be arranged corresponding to each metal barrier part 301, forming a plurality of disconnection structures, so that a cathode (i.e., the first electrode layer 60) can be disconnected several times in the transition area TA, ensuring that the disconnected cathode near the functional area HA and the metal barrier part 301 are not charged, preventing the formation of electric fields near the functional area HA.In practical applications, it is also possible to use fewer 401 insulation pieces, such as placing the 401 insulation pieces as close as possible to the display area, which can increase the area of ​​the uncharged cathode and further weaken the impact of the electric field formed by the charged cathode on the functional area.

[0041] The transition area TA also includes a winding area RA and a dummy pixel area DA. The winding area RA is located on one side of the first subarea SA1, next to the display area AA. The winding area RA is mainly used to arrange various signal connection lines. The dummy pixel area DA is located on one side of the winding area RA, next to the display area AA, and the dummy pixel area DA has the same pixel layout as the display area AA, but the pixels in the dummy pixel area DA are not used for display.

[0043] One embodiment of the present disclosure uses a flexible substrate such as substrate 10 as an example, and substrate 10 may include a flexible film and an inorganic film arranged alternately in layers. For example, substrate 10 includes a first polyimide film 11, a barrier layer 12, and a second polyimide film 13 arranged in layers. In this way, while obtaining the flexibility of substrate 10, the water and oxygen resistance performance of substrate 10 can also be improved.

[0058] Continuing with reference to FIG. 2, in the transition area TA, a first port 71 and a first signal connection line 72 are additionally formed by the second metallic layer 70, a second port 81 and a second signal connection line 82 are additionally formed by the third metallic layer 80, a first origin 91 and a third signal connection line 93 are formed by the fourth metallic layer 90, and a second origin 31 and a fourth connection line of Petition 870250108819, dated 11 / 27 / 2025, page 26 / 49 19 / 31 signal 32 are additionally formed by the first metallic layer 30. The first gate 71, the second gate 81, the first origin 91 and the second origin 31 are located in the dummy pixel area DA. The first signal connection line 72, the second signal connection line 82, the third signal connection line 93 and the fourth signal connection line 32 are located in the winding area RA.

[0059] Furthermore, in the transition area TA, a plurality of metallic barrier parts 301 are additionally formed by the first metallic layer 30, which are located in the first subarea SA1 and the second subarea SA2. A surface of the fourth inorganic insulation layer 23 is provided with a convex part 231, and the metallic barrier part 301 is arranged on one side of the convex part 231, away from the substrate 10. A cushion layer structure in the transition area TA is formed by at least one of the second metallic layer 70 and the third metallic layer 80, for example, the second metallic layer 70 further includes a first cushion layer structure arranged in the transition area TA and corresponding to the metallic barrier part 301, and / or the third metallic layer 80 also includes a second cushion layer structure arranged in the transition area TA and corresponding to the metallic barrier part 301.In one embodiment, preferably, a second cushion layer structure 501 is formed in the first subarea SA1 and in the second subarea SA2 by the third metallic layer 80. The fourth inorganic insulation layer 23 covers the second cushion layer structures 501, and the convex part 231 is formed in the corresponding second cushion layer structure 501 by the fourth inorganic insulation layer 23.

[0060] Optionally, the transition area TA also includes a third subarea SA3, located between the first subarea SA1 and the second subarea SA2. A barrier wall 601 is provided. Petition 870250108819, dated 11 / 27 / 2025, page 27 / 49 20 / 31 within the third subarea SA3, and barrier wall 601 is located on one side of the inorganic isolation layer 20, away from the substrate 10, and surrounds the functional area HA. ​​Barrier wall 601 is formed by at least one of the first planarization layer 41, the pixel definition layer 42, and the support layer 43. With reference to FIG. 2, barrier wall 601 is formed by the first planarization layer 41, and the shape of barrier wall 601 is trapezoidal. Barrier wall 601 can serve as a secondary barrier and a slight crack prevention effect when inkjet printing overflows slightly.

[0061] Furthermore, the insulation part 401 is formed by at least one of the first planarization layer 41, the pixel definition layer 42, and the support layer 43. With reference to FIG. 2, for example, the insulation part 401 is formed by the first flattened layer 41. One side of the metal barrier part 301 is covered by the insulation part 401.

[0062] In one embodiment, the first subarea SA1 is provided with a metallic barrier part 301, the insulation part 401 is located within the first subarea SA1, and the insulation part 401 is located on one side of the metallic barrier part 301, distant from the display area AA, such that, after disconnection of the first electrode layer 60 in the first subarea SA1, the first electrode layer 60, located in the first subarea SA1, close to the functional area HA, is able to not form an electric field. Obviously, the present disclosure is not limited to this. The insulation part 401 of the present disclosure may also be located on one side of the metallic barrier part 301, close to the display area AA. [00 63]Specifically, referring to FIG. 2 and FIG. 3, the metal barrier part 301 is arranged on the convex part 231 to increase the height of the metal barrier part 301, making it easier for the disconnection structure 300 to disconnect the part. Petition 870250108819, dated 11 / 27 / 2025, p. 28 / 49 21 / 31 of metallic barrier 301 disconnect the light-emitting layer 50 and the first electrode layer 60 in the disconnection structure 300. Optionally, an orthogonal projection of the metallic barrier part 301 onto the substrate 10 falls within an orthogonal projection of the convex part 231 onto the substrate 10, so that the size of the metallic barrier part 301 is less than or equal to the size of the convex part 231, in order to increase the fixed stability of the metallic barrier part 301 and prevent the collapse of the metallic barrier part 301.

[0064] Optionally, an orthogonal projection of the metallic barrier part 301 onto the substrate 10 can also cover an orthogonal projection of the convex part 231 onto the substrate 10, such that the size of the metallic barrier part 301 is larger than the size of the convex part 231. Therefore, a disconnection structure 300 can also be formed between the metallic barrier part 301 and the convex part 231, facilitating the disconnection of the light-emitting layer 50 and the first electrode layer 60.

[0065] Furthermore, the insulating part 401 is disposed on one side of the metal barrier part 301, and the insulating part 401 covers the side of the metal barrier part 301. Specifically, the metal barrier part 301 includes an upper surface 302 that is set back from the convex part 231, as well as a first side surface 303 and a second side surface 304 connecting the upper surface 302. The first side surface 303 is close to the display area AA, and the second side surface 304 is set back from the display area AA. The insulating part 401 is disposed on the second side surface 304 of the metal barrier part 301 and covers the second side surface 304 and a part of the upper surface 302. The insulating part 401 also covers a part of the convex part 231.

[0066] At least one of the surfaces of the first side 303 and of the second side surface 304 of the metal barrier part Petition 870250108819, dated 11 / 27 / 2025, page 29 / 49 22 / 31 301 is provided with a disconnection structure 300. Clearly, to ensure that the light-emitting layer 50 and the first electrode layer 60 are disconnected in the metallic barrier part 301, a side surface of the metallic barrier part 301 that is not covered by the insulating part 401 needs to be provided with a disconnection structure 300. That is, a side surface of the metallic barrier part 301 that is covered by the insulating part 401 can be provided with or without a disconnection structure 300.

[0067] Continuing with reference to FIG. 3, the light-emitting layer 50 is disconnected at the disconnect structure 300 from the metallic barrier part 301 to block the formation of an oxygen and water transport pathway through the light-emitting layer 50. The light-emitting layer 50 located on one side of the metallic barrier part 301 covers a portion of the third inorganic insulation layer 22 and the convex portion 231, and the light-emitting layer 50 located on the other side of the metallic barrier part 301 covers the metallic barrier part 301, the insulation portion 401, and the third inorganic insulation layer 22. The light-emitting layer 50 located on one side of the metallic barrier part 301 is disconnected from the light-emitting layer 50 located on the other side of the metallic barrier part 301 through the disconnect structure 300.

[0068] The first electrode layer 60 is also disconnected in the disconnection structure 300. The first electrode layer 60 located on one side of the metal barrier part 301 is electrically connected to the metal barrier part 301, and the first electrode layer 60 located on the other side of the metal barrier part 301 is insulated from the metal barrier part 301 through the insulation part 401. One side of the metal barrier part 301 and the other side of the metal barrier part 301 refer to two opposite sides of the metal barrier part 301, namely, the first lateral surface 303 and the Petition 870250108819, dated 11 / 27 / 2025, p. 30 / 49 23 / 31 second lateral surface 304 of the metal barrier part 301.

[0069] The disconnection structure 300 of the metal barrier part 301 is elaborated in detail below.

[0070] With reference to FIG. 5, the metallic barrier part 301 includes a first metallic sublayer 3011, a second metallic sublayer 3012 and a third metallic sublayer 3013 arranged in layers. The second metallic sublayer 3012 is located on one side of the first metallic sublayer 3011, away from the inorganic insulation layer 20, and the third metallic sublayer 3013 is located on one side of the second metallic sublayer 3012, away from the inorganic insulation layer 20. The material of the second metallic sublayer 3012 is different from that of the third metallic sublayer 3013, and the width of the second metallic sublayer 3012 is smaller than that of the third metallic sublayer 3013. Specifically, an outer boundary of the second metallic sublayer 3012 shrinks inward relative to an outer boundary of the third metallic sublayer 3013 to form the disconnected structure 300.Optionally, the metallic barrier part 301 is a laminated metal, such as titanium-aluminum-titanium (Ti-Al-Ti), with the first metallic sublayer 3011 and the third metallic sublayer 3013 being titanium layers, and the second metallic sublayer 3012 being an aluminum layer. Thus, when etching the titanium-aluminum-titanium laminated metal under the same etching conditions, the aluminum layer is more easily etched than the titanium layer, causing the etched aluminum layer to shrink compared to the titanium layer, forming the metallic barrier layer with the disconnected structure 300.

[0071] In this embodiment, by placing the insulation part 401 in the first subarea SA1 closest to the display area AA, the first electrode layer 60 is disconnected earlier in the transition area TA, and an area of ​​the first electrode layer 60 in Petition 870250108819, dated 11 / 27 / 2025, p. 31 / 49 The 24 / 31 TA transition area, which does not form an electric field, is increased, thus better preventing K+ migration from the polarizer to the encapsulation layer for electrochemical reactions, further improving encapsulation reliability.

[0072] In one embodiment, referring to FIG. 1 to FIG. 7, FIG. 6 is another schematic cross-sectional view along the AA' direction in FIG. 1 and FIG. 7 is a detailed schematic view of the first subarea SA1 in FIG. 6. Unlike the embodiments above, the first subarea SA1 is provided with two metal barrier parts 301, the insulation part 401 is located within the first subarea SA1, and the insulation part 401 is filled in a gap area between the two metal barrier parts 301, as shown in FIG. 6.

[0073] Specifically, referring to FIG. 7, the insulation part 401 covers two adjacent sides of the two metal barrier parts 301, and the sides of the two adjacent metal barrier parts 301 that are not covered by the insulation part 401 are provided with disconnection structures 300. The light-emitting layer 50 is disconnected at the disconnection structure 300 of the two adjacent metal barrier parts 301, and the first electrode layer 60 is also disconnected at the disconnection structure 300 of the two adjacent metal barrier parts 301.

[0074] Specifically, the two metal barrier parts 301 are defined as a first metal barrier part 301-1 and a second metal barrier part 301-2, respectively. The first metal barrier part 301-1 and the second metal barrier part 301-2 are arranged adjacent to each other in the transition area TA, and the first metal barrier part 301-1 is arranged between the second metal barrier part 301-2 and the display area AA. One side of the first metal barrier part 301-1 is adjacent to the area Petition 870250108819, dated 11 / 27 / 2025, pp. 32 / 49 Display area AA 25 / 31 is provided with a disconnect structure 300, and one side of the second metal barrier section 301-2 next to functional area HA is provided with a disconnect structure 300. The insulating section 401 simultaneously covers one side of the first metal barrier section 301-1 next to functional area HA and one side of the second metal barrier section 301-2 next to display area AA.

[0075] The light-emitting layer 50 is disconnected at the disconnect structure 300 which is located next to the first metal barrier part 301-1 near the display area AA, and is disconnected at the disconnect structure 300 which is located next to the second metal barrier part 301-2 near the functional area HA, and the light-emitting layer 50 is continuously located between the side of the first metal barrier part 301-1 near the display area AA and the side of the second metal barrier part 301-2 near the functional area HA.

[0076] The first electrode layer 60 is disconnected at the disconnect structure 300, which is located on the side of the first metal barrier part 301-1 near the display area AA, and is disconnected at the disconnect structure 300, which is located next to the second metal barrier part 301-2, near the functional area HA. ​​A first electrode layer 60, located next to the first metal barrier part 301-1, near the display area AA, is electrically connected to the first metal barrier part 301-1, and a first electrode layer 60, located next to the second metal barrier part 301-2, near the functional area HA, is electrically connected to the second metal barrier part 301-2.

[0077] More specifically, after the first electrode layer 60 is disconnected at the disconnect structure 300 of the first metallic barrier part 301-1, the first electrode layer 60 located on one side of the first barrier part Petition 870250108819, dated 11 / 27 / 2025, pp. 33 / 49 26 / 31 metallic 301-1 is electrically connected to the first metallic barrier part 301-1, and the first electrode layer 60 located on the other side of the first metallic barrier part 301-1 is insulated from the first metallic barrier part 301-1 through the insulation part 401.

[0078] The first electrode layer 60, located on the other side of the first metallic barrier part 301-1, comprises two parts. A first part is defined as a first electrode layer 60 located on one side of the first metallic barrier part 301-1 and the second metallic barrier part 301-2, away from the substrate 10, and a second part is defined as a first electrode layer 60 located on one side of the second metallic barrier part 301-2, away from the insulation layer. The two parts of the first electrode layer 60 are formed by disconnection by the disconnection structure 300 of the second metallic barrier part 301-2.The first electrode layer 60, located on the side of the second metallic barrier part 301-2, away from the insulation layer, is electrically connected to the second metallic barrier part 301-2, and the insulation part 401 separates the second metallic barrier part 301-2 from the first metallic barrier part 301-1, creating insulation between the first metallic barrier part 301-1 and the second metallic barrier part 301-2. Thus, the first electrode layer 60, electrically connected to the first metallic barrier part 301-1, is insulated, while the first electrode layer 60, electrically connected to the second metallic barrier part 301-2, is insulated.

[0079] And the first electrode layer 60, located on the side of the first metallic barrier 301-1 and the second metallic barrier 301-2, away from the substrate 10, is coated by the light-emitting layer 50, the corresponding light-emitting layer 50 being continuous. That is, the light-emitting layer 50 sequentially covers part of the upper surface of the first Petition 870250108819, dated 11 / 27 / 2025, pp. 34 / 49 27 / 31 metallic barrier 301-1, a surface of the insulating part 401 away from the substrate 10 and part of the upper surface of the second metallic barrier part 301-2, is continuous, so that the first electrode layer 60, covering part of the light-emitting layer 50, is insulated from the first metallic barrier part 301-1 and from the second metallic barrier part 301-2. In this way, the first electrode layer 60 located on one side of the first metallic barrier part 301-1 is electrically connected to the first metallic barrier part 301-1, and the first electrode layer 60 located on the other side of the first metallic barrier part 301-1 is insulated from the first metallic barrier part 301-1 through the insulating part 401.

[0080] Optionally, the same voltage is applied to the first part of the metallic barrier 301-1 and the first electrode layer 60, and no voltage is applied to the second part of the metallic barrier 301-2, meaning that the first part of the metallic barrier 301-1 is closer to the display area AA, and there is no other part of the metallic barrier 301 between the first part of the metallic barrier 301-1 and the display area AA. In this way, the first electrode layer 60 can be disconnected earlier in the transition area TA to increase an area of ​​the first electrode layer 60 that does not form an electric field in the transition area TA, thus preventing K+ migration in the polarizer to the encapsulation layer for electrochemical reactions, further improving the reliability of the encapsulation.

[0081] In this embodiment, by arranging the insulating part 401 between two adjacent metallic barrier parts 301, the first electrode layer 60 near the functional area HA and the first electrode layer 60 in the display area AA are insulated, so that the first electrode layer 60 near the functional area HA does not form an electric field and therefore does not... Petition 870250108819, dated 11 / 27 / 2025, pp. 35 / 49 28 / 31 with which K+ in the polarizer migrates to the encapsulation layer, preventing the occurrence of electrochemical reactions and improving the reliability of the encapsulation, and the problem of encapsulation failure in the tip area of ​​the perforated screen can be solved.

[0082] Furthermore, when the insulating part 401 is formed by the organic insulating layer 40 in the transition area TA, due to the fluidity of the organic material, the insulating part 401 is formed between two adjacent metallic barrier parts 301, the two adjacent metallic barrier parts 301 are able to restrict the flow of the organic material, thus forming a more stable structure of the insulating part 401. For further explanation, see the embodiments above, which cannot be repeated here.

[0083] In one embodiment, see FIGS. 1 to 8. FIG. 8 is another schematic cross-sectional view along the AA' direction in FIG. 1. Unlike the embodiments above, referring to FIG. 8, the insulating part 401 is located in the second subarea SA2, and the insulating part 401 is filled in the gap area between the two adjacent metallic barrier parts 301. By arranging the insulating part 401 in the second subarea SA2, it is also possible to obtain insulation between the first electrode layer 60 near the functional area HA and the first electrode layer 60 in the display area AA, thus preventing the first electrode layer 60 near the functional area HA from forming an electric field. For further explanations, see the embodiments above, which cannot be repeated here.

[0084] In one embodiment, referring to FIGS. 1 to 10, FIG. 9 is another detailed schematic view of the display area provided in an embodiment of the present disclosure, and FIG. 10 is a detailed schematic view of the structure of the first sub-area of ​​the film layers in FIG. 9. Unlike the embodiments above, display panel 100 adopts a transistor.

The first thin-film transistor T1 is a low-temperature polycrystalline silicon thin-film transistor, and the second thin-film transistor T2 is a metal-oxide thin-film transistor. As the display panel 100 adopts low-temperature polycrystalline oxide thin-film transistors, including more film layers, and correspondingly, in the TA transition area, the metal barrier part 301 and the pad layer structure can be formed by different metal layers.

[0085] Specifically, referring to FIG. 9, the inorganic insulation layer 20 is arranged on the substrate 10, the inorganic insulation layer 20 includes a second inorganic insulation sublayer 21, a third inorganic insulation sublayer 22, a fourth inorganic insulation sublayer 23, a fifth inorganic insulation sublayer 24, and a sixth inorganic insulation sublayer 25. The organic insulation layer 40 includes a first planarization layer 41, a pixel definition layer 42, a second planarization layer 44, and a third planarization layer 45. The first thin-film transistor T1 includes a first semiconductor layer 15, a first gate 71, a second gate 81, a first source 91, a first drain 92, a second source 31, and a third source 62. The second thin-film transistor T2 includes a second semiconductor layer 16, a third gate 83, a fourth port 17, a fourth origin 94 and a second drain 95.

[0086] Referring to FIGS. 9 and 10, a third cushion layer structure 502 is formed in the transition area TA by a metallic layer, through which the fourth gate 17 is formed in the display area AA. For further explanation, see the Petition 870250108819, dated 11 / 27 / 2025, pp. 37 / 49 30 / 31 of the above options cannot be repeated here.

Petition 870250108819, dated 11 / 27 / 2025, pp. 38 / 49 The 31 / 31 metallic part is insulated with the metallic barrier part through the insulating part. Therefore, the first electrode layer near the functional area is insulated with the first electrode layer in the display area, and the first electrode layer near the functional area may not form an electric field, thus preventing the migration of K+ in a polarizer to an encapsulation layer and electrochemical reactions, solving the problem of encapsulation failure in the cut area of ​​the perforated screen of the prior art.
