[0017] In order to help those skilled in the art better understand the present application, the following will clearly and completely describe the technical solutions in the embodiments of this specification in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0019] The features and embodiments of various aspects of this specification will be described in detail below.In addition, the features, structures, or characteristics described in this specification may be combined in any suitable manner in one or more embodiments.

[0020] Please refer to Figure 1. One embodiment of this specification provides a display panel 10, comprising a non-display area 120 and a display area 110. The non-display area 120 includes a plurality of drive units 121, each drive unit 121 correspondingly connected to a row of pixel islands 111, and each drive unit 121 includes at least two drive circuit islands 1211.

[0021] In this embodiment, the display panel 10 includes a display area 110 for displaying images and a non-display area 120 surrounding the display area 110. The display area 110 is formed by a plurality of pixel islands 111, and the non-display area 120 includes a plurality of drive units 121. Each drive unit 121 is connected to a corresponding row of pixel islands 111, and each drive unit 121 includes at least two drive circuit islands 1211. By splitting the drive units 121 in the non-display area 120 into a plurality of drive circuit islands 1211, the difference between the display area 110 and the non-display area 120 is reduced to a certain extent, and the display consistency of the display panel 10 is improved to a certain extent, thereby improving the display effect and user experience.

[0022] In some embodiments, the display panel 10 can display by controlling the pixel islands 111, thereby obtaining different display images. The driving circuit island 1211 can be a gate driving circuit (Gate in panel) such as an EM circuit and a Scan circuit, which provides a gate driving signal to the transistor devices in the pixel island 111. Each driving unit 121 is connected to a row of pixel islands 111. The driving units 121 in the same row control the transistor devices of multiple pixel islands 111 in the same row. The driving units 121 in different rows can be cascaded in row order, that is, the driving signal of the driving unit 121 in the next row is output by the driving unit 121 in the previous row. Of course, the driving signals of the driving units 121 in different rows can also be set independently.

[0023] In some embodiments, the driving unit 121 can be divided into multiple driving circuit islands 1211 according to the area of ​​the pixel island 111, so that the areas of the pixel island 111 and the driving circuit island 1211 are close to each other, thereby reducing the difference between the display area 110 and the non-display area 120 to a certain extent and improving the display effect. Specifically, for example, the area of ​​the pixel island 111 is 3nm 2 , the driver unit 121 is 9nm 2 When the driving unit 121 is split into three parts with an area of ​​3nm 2 Of course, the driving unit 121 can also be split into multiple driving circuit islands 1211 with an area close to the area of ​​the pixel island 111. Specifically, for example, the area of ​​the pixel island 111 is 2nm 2 , the driving unit 121 is 5nm 2, the driving unit 121 can be split into 1 2nm 2 The driving circuit island 1211 and a 3nm 2 The driving circuit island 1211 is divided into a plurality of driving circuit islands 1211 according to the area, and a high light transmittance area is formed between the driving circuit islands 1211, thereby improving the transparency of the non-display area 120.

[0024] In some embodiments, the driving unit 121 is further divided into multiple driving circuit islands 1211 by a division method having a smaller total area, which can reduce signal loss and reduce horizontal wiring.

[0025] In some implementations, the driver unit 121 can be further divided according to the number of components. Specifically, for example, if the driver unit 121 includes a 10T3C circuit, it can be divided into two driver circuit islands 1211 according to 5T1C and 5T2C, resulting in four transmission lines. Alternatively, it can be divided into two driver circuit islands 1211 according to 6T1C and 4T2C, resulting in three transmission lines.

[0026] In some embodiments, depending on the area of ​​the pixel island, the pixel island includes at least one pixel unit, and the pixel unit is formed by three sub-pixels of red, green, and blue. The larger the area of ​​the pixel island, the more pixel units there are, and the more transistors there are in the pixel island, then the larger the area of ​​the corresponding driving unit 121. The driving unit 121 can include a complete EM circuit and a complete Scan circuit.

[0027] In some embodiments, at least two of the multiple driving circuit islands 1211 included in each driving unit 121 are arranged in rows, so that the multiple driving circuit islands 1211 in the driving unit 121 are arranged consistently with the pixel islands 111, thereby eliminating to a certain extent the obvious boundary phenomenon between the display area 110 and the non-display area 120 caused by the inconsistent circuit arrangement between the display area 110 and the non-display area 120, thereby improving the display effect of the display panel 10 and improving the user experience.

[0028] In some embodiments, the pixel island 111 may include a TFT device and a light-emitting functional layer, and the drain electrode of the TFT device is electrically connected to the light-emitting functional layer so that the TFT device drives the light-emitting functional layer to emit light.

[0029] Please refer to Figure 1. In some embodiments, the distance between two laterally adjacent pixel islands 111 is the same as the distance between two laterally adjacent driving circuit islands 1211, and the distance between two laterally adjacent pixel islands 111 and driving circuit islands 1211 is the same; the distance between two vertically adjacent driving circuit islands 1211 is the same as the distance between two vertically adjacent pixel islands 111.

[0030] In this embodiment, the plurality of pixel islands 111 and the plurality of driving circuit islands 1211 are arranged horizontally into a plurality of rows, and the plurality of pixel islands 111 or the plurality of driving circuit islands 1211 are arranged vertically into a plurality of columns. Each row includes a plurality of pixel islands 111 and a plurality of driving units 121. The distance between two adjacent pixel islands 111 in the horizontal direction is the same as the distance between two adjacent driving circuit islands 1211 in the horizontal direction, and the distance between two adjacent pixel islands 111 and driving circuit islands 1211 in the horizontal direction is the same as the distance between two adjacent pixel islands 111 in the vertical direction. Thus, the pixel islands 111 and the driving circuit islands 1211 are arranged in a certain manner, which reduces the difference between the display area 110 and the non-display area 120 to a certain extent, thereby improving the display effect of the display panel 10.

[0031] In some embodiments, the display panel 10 includes: a plurality of pixel islands 111 forming a display area 110; wherein the plurality of pixel islands 111 and the driving circuit island 1211 are arranged according to the same arrangement rule.

[0032] In some embodiments, by arranging multiple pixel islands 111 and multiple driving circuit islands 1211 in the same manner according to the same rule, the arrangement of the pixel islands 111 in the display area 110 and the multiple driving circuit islands 1211 in the non-display area 120 is made consistent, thereby eliminating to a certain extent the obvious boundary phenomenon between the display area 110 and the non-display area 120 caused by the inconsistent circuit arrangement of the display area 110 and the non-display area 120, thereby improving the display effect of the display panel 10 and improving the user experience.

[0033] In some embodiments, the display panel 10 includes a plurality of island regions 130, each of which includes a plurality of pixel islands 111 and a plurality of driving circuit islands 1211. The plurality of island regions 130 can be arranged according to the same arrangement rule. Specifically, for example, among the plurality of island regions 130 on the display panel 10, the lateral distances between adjacent island regions 130 arranged horizontally are the same. Of course, among the plurality of island regions 130, the longitudinal distances between adjacent island regions 130 arranged vertically are the same, so that the plurality of island regions 130 are arranged according to the same arrangement rule. Alternatively, the lateral and longitudinal distances between the plurality of island regions 130 can be the same.

[0034] In some embodiments, the display panel 10 may further include a plurality of connecting lines 140, each connecting two adjacent pixel islands 111 among the plurality of pixel islands 111. The connecting lines 140 may further connect adjacent pixel islands 111 and driving circuit islands 1211, or further connect two adjacent driving circuit islands 1211. Generally, the connecting lines 140 are made of metal, thereby achieving electrical connections between the plurality of pixel islands 111, between the pixel islands 111 and the driving circuit islands 1211, and between the driving circuit islands 1211 and the driving circuit islands 1211.

[0035] 1 and 2 . In some embodiments, the pixel island 111 and the driving circuit island 1211 have the same orthographic projection shape on the substrate 260 , and the area of ​​the driving circuit island 1211 is smaller than or equal to the area of ​​the pixel island 111 .

[0036] In this embodiment, the orthographic projections of the pixel islands 111 in the display area 110 and the driving circuit islands 1211 in the non-display area 120 on the substrate 260 are identical. Specifically, for example, the orthographic projections of the pixel islands 111 and the driving circuit islands 1211 can be identical circles, identical rectangles, or other identical shapes. By making the orthographic projections of the metal of the pixel islands in the display area 110 and the driving circuit islands in the non-display area 120 identical on the substrate 260, the apparent boundary between the display area 110 and the non-display area 120 is eliminated, thereby improving the display quality of the display panel 10. The orthographic projection area of ​​the driving circuit islands 1211 is equal to the orthographic projection area of ​​the pixel islands 111, so that the metal diffraction rates of the pixel islands 111 and the driving circuit islands 1211 are consistent to a certain extent, reducing the difference between the display area 110 and the non-display area 120, thereby improving the display quality. The orthographic projection area of ​​the driver circuit island 1211 may be smaller than the orthographic projection area of ​​the pixel island 111. However, the orthographic projection area of ​​the driver circuit island 1211 should not be too small, as this can increase the transmittance of the non-display area, thereby improving the display effect. Specifically, for example, the ratio of the orthographic projection area of ​​the driver circuit island 1211 to the orthographic projection area of ​​the pixel island 111 is in a range of 70% to 100%.

[0037] In some embodiments, the shapes of the orthographic projections of the pixel island 111 and the driving circuit island 1211 on the substrate 260 may be different. In this case, a metal layer may be covered on the driving circuit island 1211 so that the orthographic projection of the driving circuit island 1211 on the substrate 260 has the same shape as the orthographic projection of the pixel island 111 on the substrate 260. The orthographic projection of the driving circuit island 1211 on the substrate 260 and the orthographic projection area of ​​the pixel island 111 on the substrate 260 may also be made the same, so that the light diffraction conditions of the pixel island 111 and the driving circuit island 1211 are consistent, thereby making the light diffraction conditions of the display area 110 and the non-display area 120 consistent, thereby blurring the boundary between the display area 110 and the non-display area 120, and thus improving the display effect of the display panel 10.

[0038] In some embodiments, the display panel includes multiple islands 130, each of which includes multiple pixel islands 111 and multiple driver circuit islands 1211. The orthographic projections of the multiple islands 130 on the substrate 206 are identical in shape, and the multiple connecting lines 140 connecting the multiple islands 130 are identical in shape and size. This ensures that the connecting lines 140 and adjacent islands 130 have the same shape and size, thereby blurring the distinction between the display area 110 and the non-display area 120 to a certain extent, thereby improving the display effect. Of course, the connecting lines 140 horizontally connecting the multiple islands 130 and the connecting lines 140 vertically connecting the multiple islands 130 have the same shape.

[0039] Please refer to Figure 2. In some embodiments, the driving circuit island 1211 includes a driving array structure 250 and a first metal shielding layer 240; the driving array structure 250 is located between the first metal shielding layer 240 and the substrate 260; wherein the orthographic projection of the driving array structure 250 on the substrate 260 is located within the orthographic projection of the first metal shielding layer 240 on the substrate 260; and the orthographic projection of the first metal shielding layer 240 on the substrate 260 coincides with the orthographic projection of the driving array structure 250 on the substrate 260.

[0040] In this embodiment, the driving circuit island 1211 includes a driving array structure 250 and a first metal shielding layer 240 for shielding the array structure 250. The driving array structure 250 is located between the first metal shielding layer 240 and the substrate 260, that is, the first metal shielding layer 240 is located on the side of the driving array structure 250 away from the substrate 260. The orthographic projection of the first metal shielding layer 240 on the substrate 260 can overlap with the orthographic projection of the driving array structure 250 on the substrate 260, thereby improving the effect of the first metal shielding layer 240 in shielding the driving array structure 250. The first metal shielding layer 240 covers multiple driving array structures 250, reducing the metal diffraction rate, improving display consistency, and thus improving the display effect.

[0041] The driving array structure 250 includes transistors and capacitors that constitute the EM and Scan circuits.

[0042] In some embodiments, a pixel island includes at least one pixel circuit and at least one light-emitting functional layer, wherein one pixel circuit is electrically connected to one light-emitting functional layer to drive the light-emitting functional layer to emit light. The pixel circuit is formed by at least two transistors, which may be thin film transistors (TFTs).

[0043] The electrodes 221 of some TFT structures 220 in the pixel island 111 are electrically connected to the light-emitting electrode layer 210 to drive the light-emitting functional layer to emit light. The pixel island 111 may also have a second metal shielding layer 230 that shields the TFT structure 220. This second metal shielding layer 230 can be provided on the same layer as the drain electrode 221 of the TFT structure 220 in the pixel island 111, as well as the first metal shielding layer 240. This allows the pixel island 111 to form the same pattern as the driving circuit island 1211, thereby reducing the display difference between the display area 110 and the non-display area 120, thereby improving the display quality of the display panel 10. The second metal shielding layer 230 can be electrically connected to the drain electrode of the driving TFT structure to transmit a reset voltage signal or a power supply voltage signal to reduce transmission loss.

[0044] In some embodiments, the second metal blocking layer 230 and the first metal blocking layer 240 of the TFT structure 220 that blocks the pixel island 111 can be formed by the same layer of metal, or of course can be metal layers of the same material, so that the light diffraction conditions of the display area 110 and the non-display area 120 are consistent.

[0045] 1 and 2 . In some embodiments, the display panel 10 includes transparent areas 151 , and the orthographic projections of each transparent area 151 of the display panel 10 on the substrate 260 are the same in shape; the transparent areas 151 are surrounded by pixel islands 111 and / or driving circuit islands 1211 .

[0046] The density of the transparent areas 151 in the display area 110 is the same as the density of the transparent areas 151 in the non-display area 120, that is, within the same area, the number of transparent areas 151 in the display area 110 is the same as the number of transparent areas 151 in the non-display area 120, and the appearance structure of the display area 110 and the non-display area 120 are consistent, which reduces the difference between the display area 110 and the non-display area 120, thereby improving the transparent display effect of the display panel 10.

[0047] A first connection line 141 is provided between two adjacent pixel islands 111 , a second connection line 142 is provided between adjacent pixel islands 111 and driving circuit islands 1211 , and a third connection line 143 is provided between two adjacent driving circuit islands 1211 .

[0048] In this embodiment, the display panel 10 includes a transparent area 151, and the display area 110 and the non-display area 120 include the transparent area 151. The transparent area 151 has the same positive projection on the substrate 260, and the transparent area 151 is surrounded by a pixel island 111 and / or a driving circuit island 1211. Specifically, for example, the transparent area 151 is surrounded by a pixel island 111, and the transparent area 151 may also be surrounded by a driving circuit island 1211. The transparent area 151 is surrounded by the pixel island 111 and the driving circuit island 1211, so that the transparent areas 151 of the display area 110 and the non-display area 120 are the same, reducing the difference between the display area 110 and the non-display area 120, thereby improving the display effect of the display panel 10.

[0049] In this embodiment, a first connection line 141 is provided between two adjacent pixel islands 111 , a second connection line 142 is provided between adjacent pixel islands 111 and driving circuit islands 1211 , and a third connection line 143 is provided between two adjacent driving circuit islands 1211 .

[0050] Refer to Figure 1. In some embodiments, the plurality of pixel islands 111 and the plurality of driving circuit islands 1211 constitute a plurality of island regions 130; wherein connecting lines 140 are disposed between the plurality of island regions 130, and four adjacent island regions 130 and connecting lines 140 form an adjacent island unit 150, wherein transparent regions 151 are respectively formed in the plurality of adjacent island units 150, and the area ratio of the transparent regions 151 in each adjacent island unit 150 is the same;

[0051] In some embodiments, in order to form an electrical connection between multiple island areas 130, a connecting line 140 is set between the multiple island areas 130, and four adjacent island areas 130 are connected through the connecting line 140 to form an adjacent island unit 150. The display panel 10 has multiple adjacent island units 150, which may include four adjacent pixel islands 111 in the display area 110 and the connecting line 140 to form an adjacent island unit 150, and may also include two pixel islands 111 at the junction of the display area 110 and the non-display area 120 and two driving circuit islands 1211 formed by the connecting line 140. The adjacent island unit 150 may also include four driving circuit islands 1211 in the non-display area 120 formed by the connecting line 140.

[0052] In some embodiments, a transparent area 151 is formed in each of a plurality of adjacent island units 150. The display panel 10 includes a plurality of adjacent island units 150, each of which may include an island area 130, a connecting line 140, and a transparent area 151. The transparent area 151 is the portion of the adjacent island unit 150 where the island area 130 and the connecting line 140 are not provided, and is free of other metal parts. The plurality of islands 130 are arranged such that the transparent areas 151 in the adjacent island units 150 have the same area ratio, thereby ensuring that the arrangement of the plurality of islands 130 in different areas of the display panel 10 is the same, thereby eliminating the difference between the display area 110 and the non-display area 120, reducing the difference in transmittance between the display area 110 and the non-display area 120, thereby improving the uniformity of the display area 110 and the non-display area 120, and enhancing the display effect of the display panel 10.

[0053] In some embodiments, the area ratio is expressed as the ratio of the area of ​​the transparent region 151 in the adjacent island unit 150 to the area of ​​the adjacent island unit 150. The area of ​​the adjacent island unit 150 may include the sum of the areas of the four island regions 130, the four connecting lines 140, and the transparent region 151 of the adjacent island unit 150. Specifically, for example, the area of ​​the adjacent island unit 150 is 20 nm. 2 , the area of ​​the transparent region 151 is 16nm 2 , which accounts for 4 / 5 of the area.

[0054] Please refer to Figure 1. In some embodiments, the horizontal arrangement rule and the vertical arrangement rule of the plurality of adjacent island units 150 in the display panel 10 are respectively the same.

[0055] In some embodiments, the plurality of adjacent island units 150 in the display panel 10 can be arranged according to the same horizontal arrangement rule as the plurality of adjacent island units 150 in each row. Specifically, for example, the horizontal arrangement rule can be that the distances between the adjacent island units 150 in each row are the same, or the distances between the adjacent island units 150 are different, but when the adjacent island units 150 between multiple rows are projected perpendicular to the row direction, the orthographic projections of the island units 150 between rows overlap. The plurality of adjacent island units 150 can be arranged according to the same vertical arrangement rule as the plurality of adjacent island units 150 in each column. The vertical arrangement rule can also be that the distances between the adjacent island units 150 in each column are the same, or the orthographic projections of the adjacent island units 150 between multiple columns overlap.

[0056] Please refer to Figure 1. In some embodiments, the connecting lines 140 include a first connecting line 141 between pixel islands 111, a second connecting line 142 between the pixel island 111 and the driving circuit island 1211, and a third connecting line 143 between the driving circuit island 1211 and the driving circuit island 1211. The second connecting line 142 and the third connecting line 143 include: a plurality of lines for transmitting signals, and a shielding line arranged on the side of the line away from the substrate 260, and the shape of the shielding line is the same as that of the first connecting line, and the shielding line is arranged in the same layer as the first metal shielding layer 240; preferably, the orthographic projection of the shielding line on the substrate 260 covers the orthographic projection of the line on the substrate 260.

[0057] In this embodiment, the first connecting line 141 is used to connect multiple pixel islands 111, the second connecting line 142 is used to connect between the pixel island 111 and the driving circuit island 1211, and the third connecting line 143 is used to connect between the driving circuit islands. The second connecting line 142 and the third connecting line 143 include multiple circuits and shielding lines for transmitting signals. The multiple circuits are respectively connected to the pixel island 111 and the driving circuit island 1211 for signal transmission. The shielding line is stacked with multiple circuits, and the shielding line is stacked above the circuit, that is, the shielding layer is arranged on the side of the circuit away from the substrate. Of course, there is an isolation layer between the shielding line and the circuit, and there may also be other layers that are not electrically connected. The orthographic projection of the blocking line on the substrate 260 covers the corresponding circuit. The blocking line blocks multiple circuits. The shape of the blocking line is the same as the shape of the first connecting line 141, so that the orthographic projections of the second connecting line 142 and the third connecting line 143 on the substrate 260 are the same as the orthographic projection of the first connecting line 141 on the substrate, reducing the difference between the display area 110 and the non-display area 120, thereby improving the consistency between the display area 110 and the non-display area 120, and thus improving the display effect of the display panel 10.

[0058] In some embodiments, the non-display area 120 may not include the driving circuit island 1211 , and the second connection line 142 may include a shielding line having the same pattern as that formed by the first connection line 141 . The shielding line may be used to transmit signals.

[0059] Please refer to Figure 3. In some embodiments, the plurality of island regions 130 further include one or more metal islands 123 located in the non-display region 120. The metal islands 123 and the orthographic projection of the pixel islands 111 on the substrate 260 form the same shape, and the area of ​​the metal islands 123 is less than or equal to the area of ​​the pixel 111. Preferably, fourth connecting lines 145 are provided between the metal islands 123 and the pixel islands 111 and / or the driving circuit islands 1211. Preferably, fifth connecting lines 144 are provided between the metal islands 123.

[0060] In this embodiment, when there are no driving circuit islands 1211 in the non-display area 123, one or more metal islands 123 are provided in the non-display area 120. The orthographic projection of the metal islands 123 onto the substrate is the same as the orthographic projection of the pixel islands 111 onto the substrate, thereby improving the consistency between the display area 110 and the non-display area 1201, thereby enhancing the display quality of the display panel 10. The orthographic projection area of ​​the metal islands 123 can be equal to the orthographic projection area of ​​the pixel islands 111, thereby reducing the metal transmittance of the display area 110 and the non-display area 120 and reducing the display difference between the display area 110 and the non-display area 120, thereby improving the display quality. The orthographic projection area of ​​the metal islands 123 can be smaller than the orthographic projection area of ​​the pixel islands 111, but not too small, so that the orthographic projection area of ​​the metal islands 123 is close to the orthographic projection area of ​​the pixel islands 111. While ensuring consistency between the display area 110 and the non-display area 120, it can also increase the transmittance of the non-display area 120, thereby improving the display quality.

[0061] In this embodiment, when there is no driving circuit island 1211 in the non-display area 120, one or more metal islands 123 are set in the non-display area 120, and the orthographic projection of the metal island 123 on the substrate 260 is consistent with or close to the orthographic projection of the pixel island 111 on the substrate 260, ensuring that the transparent area density of the non-display area 120 is the same as the transparent area density of the display area 110, thereby improving the consistency between the display area 110 and the non-display area 120, thereby improving the display effect of the display panel 10.

[0062] In some embodiments, a fourth connection line 145 is disposed between the metal island and the pixel island and / or the driving circuit island.

[0063] In some embodiments, a fourth connection line 145 is provided between the metal island 123 and the pixel island 111. The fourth connection line 145 can be used to transmit signals and improve the consistency between the display area 110 and the non-display area 120, thereby improving the display effect.

[0064] In some embodiments, a fourth connection line 145 is provided between the metal island 123 and the driving circuit island 1211 . The fourth connection line can be used to transmit signals and also improve the consistency between the display area 110 and the non-display area 120 , thereby improving the display effect.

[0065] In some embodiments, a fifth connecting line 144 is arranged between the multiple metal islands 123, and the orthographic projection of the fifth connecting line 144 on the substrate 260 is the same as the shape and area of ​​the orthographic projection of the first connecting line 141 on the substrate 260, thereby improving the consistency between the non-display area 120 and the display area 110 to a certain extent, thereby improving the display effect.

[0066] In some embodiments, the fifth connection lines 144 between the plurality of metal islands 123 can be used to transmit signals, thereby saving costs.

[0067] In some embodiments, the plurality of metal islands 123 and the plurality of fifth connection lines 144 are provided based on the same metal layer, which reduces process difficulty and saves cost.

[0068] In some embodiments, one or more metal islands 123 and the plurality of fourth connection lines 145 are provided based on the same metal layer, which reduces process difficulty and saves costs.

[0069] In some embodiments, the metal island 123 and the shielding line are provided in the same layer.

[0070] In this embodiment, multiple metal islands 123 and multiple fifth connecting lines 144 can be formed by etching the same metal layer. Of course, they can also be formed by other methods. Formation based on the same metal layer can reduce production costs, improve production efficiency, and improve the consistency between the multiple metal islands 123 and the multiple fifth connecting lines 144, thereby improving the display consistency of the non-display area 120, thereby improving the display effect of the display panel.

[0071] 4 , in some embodiments, the pixel island 111 has a light-emitting electrode transition layer 231 , which is disposed on the same layer as the first metal shielding layer 240 and is electrically disconnected from the first metal shielding layer 240 .

[0072] In this embodiment, to prevent the light-emitting electrode layer 210 from failing to cover the TFT structure 220 in the pixel circuit, resulting in an irregular pixel island shape that differs significantly from the metal island 123 or the first metal shielding layer 240, and thus significantly differs from the appearance of the non-display area, a light-emitting electrode transition layer 231 is provided between the light-emitting electrode layer 210 and the drain electrode 221 of the TFT structure 220. Disposing the light-emitting electrode transition layer 231 in the same layer as the first metal shielding layer 240 ensures consistent metal transmittance between the display area 110 and the non-display area 120, thereby improving the consistency between the display area 110 and the non-display area 120 and enhancing the display quality of the display panel 10. The light-emitting electrode transition layer 231 can be electrically connected to the drain electrode of the driving TFT structure to transmit a reset voltage signal or a power supply voltage signal, thereby reducing transmission losses. The light-emitting electrode transition layer 231 is electrically disconnected from the first metal shielding layer 240, thereby preventing short circuits caused by signal transmission between the display area 110 and the non-display area 120.
