In some alternative embodiments, please refer to fig. 1 and fig. 6 in combination, fig. 6 is another cross-sectional structure schematic diagram in a direction of a-a' in fig. 1, in the present embodiment, in the first non-display area NA1, the first insulating layer 20 includes a plurality of first openings 20K, and in a direction Z perpendicular to the light emitting surface of the display panel 000, the first openings 20K penetrate through the first insulating layer 20;

the orthographic projection of the first portion 301 on the light-emitting surface of the display panel 000 is located within the orthographic projection range of the first opening 20K on the light-emitting surface of the display panel 000.

The present embodiment explains that within the range of the first non-display area NA1, the first insulating layer 20 may be provided with a plurality of first openings 20K penetrating through the thickness of the first insulating layer 20, alternatively, as shown in fig. 6, each of the first openings 20K may be a long-stripe structure disposed around a portion of the display area AA, and the plurality of first openings 20K may be sequentially arranged at intervals along a direction in which the first non-display area NA1 points to the display area AA. In the embodiment, the first insulating layer 20 is provided with the plurality of first openings 20K in the first non-display area NA1 on the side of the retaining wall B away from the display area AA, so that the possibility that the crack extends to the display area AA in the panel cutting process can be reduced by using the plurality of first openings 20K, and the crack extension can be prevented. In this embodiment, the orthographic projection of the first portion 301 on the light-emitting surface of the display panel 000 is disposed within the orthographic projection range of the first opening 20K on the light-emitting surface of the display panel 000, that is, the orthographic projection of the first opening 20K on the light-emitting surface of the display panel 000 covers the orthographic projection of the first portion 301 on the light-emitting surface of the display panel 000, optionally, in the direction Z perpendicular to the light-emitting surface of the display panel 000, the first portion 301 and the first opening 20K overlap each other, and when the first opening 20K is of a structure penetrating through the thickness of the first insulating layer 20, the first portion 301 can be just embedded into the first opening 20K, so that the orthographic projection of the light-emitting surface of the display panel 000 through the first portion 301 is disposed within the orthographic projection range of the light-emitting surface of the first opening 20K on the light-emitting surface of the display panel 000, so that the first portion 301 can just be embedded into the first opening 20K, which is favorable for reducing the distance between the first portion 301 and the first conductive layer 102 in the direction Z perpendicular to the light-emitting surface of the display panel 000, since the capacitance of the capacitor mainly depends on the facing area, the inter-plate distance and the medium itself, i.e. according to the capacitance calculation formula C ∈ S/4 π kd (where ∈ is a constant, S is the facing area of the capacitor plate, d is the distance between the capacitor plates, and k is a constant of the electrostatic force), when the distance between the first portion 301 and the first conductive layer 102 decreases in the direction Z perpendicular to the light-emitting surface of the display panel 000, the capacitance of the first storage capacitor Cst1 formed by the first portion 301 and the first conductive layer 102 increases, and thus the capacity of storing charges increases. Therefore, the orthographic projection of the first portion 301 on the light-emitting surface of the display panel 000 is disposed in the orthographic projection range of the first opening 20K on the light-emitting surface of the display panel 000, so that the increase of the NA width of the non-display area to realize a narrow frame can be avoided, and the capacitance of the first storage capacitor Cst1 formed by the first portion 301 and the first conductive layer 102 can be increased, thereby improving the electrostatic protection capability, further slowing down the speed of static electricity entering the display panel 000, and better improving the display quality.

The amorphous silicon has the acceptor type and donor type local energy bands in the Si-H band gap, and has the double function of compounding positive and negative ions, so that when the first substrate 10 is stripped by laser, the influence of an electric field formed by mobile charges possibly existing in the first substrate 101 on a thin film transistor T0 of the drive circuit layer 001 can be shielded, light of the whole wave band can be absorbed, the light shielding effect on an active layer of the thin film transistor T0 of the drive circuit layer 001 can be realized, the problems of metal reflection, heating and the like do not exist, and the reliability is favorably improved. Indium tin oxide or indium gallium zinc oxide in the composite metal oxide is a transparent metal oxide semiconductor material, has similar effect to amorphous silicon semiconductor material, can block the influence of mobile charges possibly existing in the first substrate 101 on the upper layer, and can block part of external environment light at the bottom or the influence of heat energy in a laser stripping process in a flexible process on a thin film transistor T0 in the driving circuit layer 001.

In this embodiment, the facing area of the first portion 301 and the first conductive layer 102 is not specifically limited, and the facing area of the first portion 301 and the first conductive layer 102 may be designed as large as possible while meeting the requirement of a narrow frame, which is beneficial to better improving the electrostatic protection capability of the display panel 000.

It is understood that the first opening 20K and the first recess 1031 of the present embodiment may be both long-strip structures disposed around a portion of the display area AA, and the first portion 301 of the present embodiment may be a long-strip structure, or may be a segmented structure disposed at the same position of the first recess 1031, and the shape of the first portion 301 is not particularly limited in the present embodiment, and in the specific implementation, the first opening and the first recess 1031 may be selectively disposed according to actual requirements.

In some alternative embodiments, referring to fig. 10, fig. 10 is a schematic plan view illustrating another planar structure of a display panel according to an embodiment of the present invention, in this embodiment, a first portion 301 of the first metal layer 30 disposed in the first non-display area NA1 is a strip structure disposed around the display area AA; the first portion 301 is connected to a fixed potential signal terminal.

This embodiment explains that the first portion 301 and the first conductive layer 102 for reducing the transmission speed of the electrostatic charges to the display area AA form one plate of the first storage capacitor Cst1, that is, the first portion 301 may have a long bar structure, so that the area of the first storage capacitor Cst1 opposite to the first conductive layer 102 may be made as large as possible, which is beneficial to increase the charge storage capacity of the capacitor and reduce the transmission speed of the electrostatic charges.

In some alternative embodiments, referring to fig. 11, fig. 11 is a schematic plan view of another display panel provided in the embodiments of the present invention, in which in the embodiments, the first metal layer 30 includes a plurality of first portions 301, and the plurality of first portions 301 are arranged at intervals along a direction in which the first non-display area NA1 points to the display area AA.

The embodiment explains that the first metal layer 30 may be provided with a plurality of first portions 301 in the range of the first non-display area NA1, the plurality of first portions 301 are arranged at intervals along the direction in which the first non-display area NA1 points to the display area AA, optionally, the first metal layer 30 may be provided with 2 to 5 first portions 301 in the range of the first non-display area NA1, further optionally, the first portions 301 of the embodiment may be a long-strip structure disposed around a part of the display area AA, so that it is avoided that the excessive number of first portions 301 are not favorable for realizing the narrow frame design of the display panel 000, and at the same time, it is also avoided that the facing area with the first conductive layer 102 is too small due to the too small number of first portions 301, which affects the charge storage capability of the capacitor, and is further not favorable for the transmission speed of static electricity reduction.

It is to be understood that, in fig. 11 of this embodiment, the 5 first portions 301 are exemplified to be arranged at intervals along the direction in which the first non-display area NA1 points to the display area AA, and in specific implementation, the number of the plurality of first portions 301 arranged at intervals along the direction in which the first non-display area NA1 points to the display area AA includes, but is not limited to, this, and other arrangement structures may also be adopted.

In some alternative embodiments, with reference to fig. 11, in the present embodiment, along the direction in which the first non-display area NA1 points to the display area AA, one first portion 301 of the two adjacent first portions 301 is connected to a positive voltage signal terminal, and the other first portion 301 is connected to a negative voltage signal terminal.

In some alternative embodiments, please refer to fig. 12 and 13 in combination, fig. 12 is a schematic plan view illustrating a display panel according to an embodiment of the present invention, and fig. 13 is a partial enlarged view of an area M in fig. 12, in this embodiment, the first portion 301 includes a plurality of first sub-portions 3011, and the plurality of first sub-portions 3011 are disposed at intervals along the first direction X; in a direction parallel to the light emitting surface of the display panel 000, the first direction X intersects with a direction in which the first non-display area NA1 points to the display area AA.

The present embodiment explains that the first portion 301 disposed on the first metal layer 30 may also be a segmented structure, and specifically, the first portion 301 includes a plurality of first sub-portions 3011, and the plurality of first sub-portions 3011 are disposed at intervals along a first direction X, where the first direction X can be understood as a direction intersecting a direction in which the first non-display area NA1 points to the display area AA in a direction parallel to the light-emitting surface of the display panel 000, for example, when the first non-display area NA1 is a partial area in a left frame and a right frame of the display area AA illustrated in fig. 12, the first direction X at this time may be the direction illustrated in fig. 12, and when the first non-display area NA1 is a partial area in a frame on the display area AA illustrated in fig. 12, the first direction X at this time may be a transverse direction illustrated in fig. 12 (not illustrated in the drawings). The present embodiment provides a segmented structure in which the first portion 301 includes a plurality of first sub-portions 3011 spaced apart in the first direction X, and can avoid accumulation of electrostatic charges on the first portion 301.

Alternatively, as shown in fig. 12 and fig. 13, the first portion 301 in this embodiment may include a plurality of first portions 301, the plurality of first portions 301 may be sequentially arranged at intervals along a direction in which the first non-display area NA1 points to the display area AA, and each first portion 301 may be a segmented structure including a plurality of first sub-portions 3011 arranged at intervals along the first direction X, so that accumulation of electrostatic charges on the first portion 301 may be avoided, and meanwhile, by arranging the plurality of first portions 301, the charge storage capability of a capacitor formed by the first portion 301 and the first conductive layer 102 may be enhanced, thereby further better enhancing the electrostatic protection effect of the display panel 000.

Alternatively, as shown in fig. 12, in a direction in which the first non-display area NA1 points to the display area AA, two adjacent first portions 301 include an a-th first portion 301 (e.g., 301A in fig. 12) and an a + 1-th first portion 301 (e.g., 301B in fig. 12), where a is a positive integer; along the first direction X, two adjacent first sub-portions 3011 of the same first portion 301 include a spacer F therebetween;

in a direction in which the first non-display area NA1 points toward the display area AA, the spacer F (e.g., the spacer F1 in fig. 12) of the a-th first section 301 (e.g., 301A in fig. 12) does not overlap with the spacer F (e.g., the spacer F2 in fig. 12) of the a + 1-th first section 301 (e.g., 301B in fig. 12).

This embodiment explains that the first section 301 in the range of the first non-display area NA1 may be provided as a segmented structure including a plurality of first sub-sections 3011, accumulation of static electricity may be avoided, and by providing that the first non-display area NA1 points in the direction of the display area AA, the adjacent two first sections 301 include spacer sections F that do not overlap, that is, as shown in fig. 12, the first sub-sections 3011 of the adjacent two first sections 301 are alternately staggered, and one spacer section F1 of the first section 301A overlaps one first sub-section 3011 of the first section 301B and does not overlap with a spacer section F2 between adjacent two first sub-sections 3011 in the first section 301B in the direction in which the first non-display area NA1 points in the display area AA, and that a crack may be prevented from extending in the direction of the display area AA by the staggered arrangement of the first sub-sections 3011, for example, when the crack G illustrated in fig. 13 extends from one spacer section F1 of the first section 301A to the second section 301B, since the spacers F2 and F1 of the second portion 301B do not overlap in the direction in which the first non-display area NA1 points to the display area AA, the crack G is prevented by the first portion 3011 of the first portion 301B when extending from the spacer F1 to the display area AA, thereby being beneficial to ensuring the product yield.

In some alternative embodiments, please refer to fig. 12 and 13 in combination, in this embodiment, along the first direction X, i.e. along the arrangement direction of the plurality of first sub-portions 3011 in the same first portion 301, the length h of the first sub-portion 3011 ranges from 50 um to 100 um.

The present embodiment explains that the first portion 301 in the range of the first non-display area NA1 is configured as a segmented structure including a plurality of first sub-portions 3011, so as to avoid electrostatic accumulation, the length h of each segmented first sub-portion 3011 in the first direction X ranges from 50 to 100um, so as to avoid electrostatic accumulation caused by too long length h of the first sub-portion 3011, which affects display quality, and also avoid increasing process difficulty caused by too short length h of the first sub-portion 3011, and further, in the present embodiment, the length h of the first sub-portion 3011 in the first direction X ranges from 50 to 100um, which is beneficial to ensuring electrostatic protection effect and reducing process difficulty.

It can be understood that, in this embodiment, the lengths h of the plurality of first sub-portions 3011 included in each first portion 301 in the first direction X may be equal or unequal, and only the length h of the first sub-portion 3011 in the first direction X ranges from 50 to 100um, and this embodiment does not specifically limit whether the lengths of the different first sub-portions 3011 are equal, and in specific implementation, the lengths may be selected and set according to actual requirements.

In some alternative embodiments, please continue to refer to fig. 12 and 13 in combination, in the present embodiment, the width n1 of the first portion 301 along the direction in which the first non-display area NA1 points to the display area AA ranges from 3 um to 5 um.

The present embodiment explains that the width n1 of the first portion 301 disposed on the first metal layer 30 in the direction in which the first non-display area NA1 points to the display area AA may be between 3 μm and 5 μm, so that it is possible to avoid that the width n1 of the first portion 301 in the direction in which the first non-display area NA1 points to the display area AA is too wide, which causes too much space to be occupied by the frame area, which is not favorable for implementing a narrow frame design, and it is also possible to avoid that the width n1 of the first portion 301 in the direction in which the first non-display area NA1 points to the display area AA is too narrow, which affects the charge storage capability of the first storage capacitor formed by the first portion 301 and the first conductive layer 102. Therefore, in the embodiment, the first non-display area NA1 is arranged to point to the display area AA, and the width n1 of the first portion 301 is in a range of 3-5 μm, which is not only beneficial to realizing a narrow frame, but also beneficial to enhancing the charge storage capability of the first storage capacitor formed by the first portion 301 and the first conductive layer 102, and beneficial to improving the electrostatic protection effect.

Optionally, a width n2 of the first opening 20K of the first insulation layer 20 in the direction from the first non-display region NA1 to the display region AA may be less than or equal to 7 μm, and n2 is greater than or equal to n1, a width n3 of the first groove 1031 opened on the surface of the second substrate 103 on the side away from the first substrate 101 in the direction from the first non-display region NA1 to the display region AA may also be less than or equal to 7 μm, and n3 is greater than or equal to n1, so that a forward projection of the first portion 301 on the light-emitting surface of the display panel 000 may be located in a forward projection range of the first opening 20K or the first groove 1031 on the light-emitting surface of the display panel 000, and the first portion 301 may just fall into the first opening 20K and the first groove 1031, so that a surface of the first portion 301 on the side facing the first substrate 101 may directly contact with the first groove 1031, which is favorable for avoiding the influence of the width n2 of the groove bottom 1031 of the first opening 20K and the narrow border design of the groove 3, thereby achieving the narrow border design Meanwhile, the distance between the first portion 301 and the first conductive layer 102 can be reduced, and the charge storage capacity of the first storage capacitor formed by the first portion 301 and the first conductive layer 102 can be further improved.

In some alternative embodiments, with continuing reference to fig. 1 and fig. 2, in this embodiment, the display panel 000 of the display area AA further includes a plurality of thin film transistors T0, the thin film transistor T0 at least includes a gate T0G, a source T0S and a drain T0D; the source T0S and the drain T0D are located in the first metal layer 30.

This embodiment explains that the first portion 301 in the range of the first non-display area NA1 can be made of the same material as the source T0S and the drain T0D of the thin film transistor T0, and optionally, the thin film transistor T0 can be any one of the transistors disposed in the driving circuit layer 001 of the display panel 000, since the metal film layer where the source T0S and the drain T0D of the thin film transistor T0 are disposed is generally made of a triple layer formed by Ti/Al/Ti (titanium/aluminum/titanium), and the metal film layer where the gate T0G of the thin film transistor T0 is disposed is generally made of a Mo (molybdenum) layer, the metal film layer where the source T0S and the drain T0D of the thin film transistor T0 are disposed is more flexible than the metal film layer where the gate T0G of the thin film transistor T0 is disposed, and therefore, the first portion 301 is disposed on the same layer as the source T0S and the drain T0D of the thin film transistor T0, which is favorable for releasing stress, thereby preventing the crack from extending effectively. In addition, in the embodiment, the first portion 301 is disposed on the same layer as the source T0S and the drain T0D of the tft T0, and it can be avoided that when the first portion 301 is disposed on another metal film layer on the side of the metal film layer where the source T0S and the drain T0D of the tft T0 are located away from the first substrate 10, the first portion 301 and the first conductive layer 102 are too far apart in the direction Z perpendicular to the light emitting surface of the display panel, which may affect the charge storage capability of the first storage capacitor formed by the first portion 301 and the first conductive layer 102. Therefore, in the embodiment, the first portion 301 in the range of the first non-display area NA1 is made of the same material and by the same process as the source T0S and the drain T0D of the thin film transistor T0, which is beneficial to improving the crack extension resistance of the first portion 301, and simultaneously, the charge storage capacity of the first storage capacitor formed by the first portion 301 and the first conductive layer 102 can be ensured, so as to improve the product yield and the display quality of the display panel 000.

the second groove 1032 includes at least a first cavity 1032A and a second cavity 1032B, and in the direction Z perpendicular to the light emitting surface of the display panel 000, the first cavity 1032A is located on a side of the second cavity 1032B facing the first substrate 101;

the inner diameter D1 of the first cavity 1032A is larger than the inner diameter D2 of the second cavity 1032B along the direction parallel to the light emitting surface of the display panel 000;

the display panel 000 further includes a thin film encapsulation layer 007 and a first inorganic layer 0010, the thin film encapsulation layer 007 is located on a side of the second substrate 103 away from the first substrate 101, and the first inorganic layer 0010 is located on a side of the thin film encapsulation layer 007 away from the first substrate 101;

the thin film encapsulation layer 007 and the first inorganic layer 0010 are in contact with at least the sidewalls 10320 of the second recess 1032.

This embodiment explains that on the first base 10 of the display panel 000, within the range of the first non-display area NA1, the side of the second substrate 103 facing away from the first substrate 101 may further include a plurality of second grooves 1032, and along the direction from the first non-display area NA1 to the display area AA, the plurality of second grooves 1032 are located between the first portion 301 and the retaining wall B, that is, the plurality of second grooves 1032 are located on the side of the retaining wall B away from the display area AA, and the plurality of second grooves 1032 are located on the side of the first portion 301 close to the display area AA. The plurality of second grooves 1032 are arranged at intervals along a direction in which the first non-display area NA1 points to the display area AA, and the second grooves 1032 do not penetrate through the thickness of the second substrate 103 in a direction perpendicular to the light emitting surface of the display panel 000. Optionally, in a direction in which the first non-display area NA1 points to the display area AA, the number of the second recesses 1032 located between the first part 301 and the retaining wall B may also be one, and the specific number of the second recesses 1032 is not limited in this embodiment. Alternatively, as shown in fig. 14, each second groove 1032 may be a long-bar structure disposed around a portion of the display area AA, so as to facilitate a process for manufacturing the second groove 1032 on a side surface of the second substrate 103 facing away from the first substrate 101.

The second groove 1032 in this embodiment at least includes a first cavity 1032A and a second cavity 1032B, wherein in the direction Z perpendicular to the light emitting surface of the display panel 000, the first cavity 1032A is located on a side of the second cavity 1032B facing the first substrate 101, and along a direction parallel to the light emitting surface of the display panel 000, an inner diameter D1 of the first cavity 1032A is larger than an inner diameter D2 of the second cavity 1032B, that is, a cross section (as illustrated in fig. 15 and 16) of the second groove 1032 opened on a side of the second substrate 103 facing away from the first substrate 101 in this embodiment is a structure with a narrow top and a wide bottom, since the organic light emitting material is manufactured by an evaporation process in the manufacturing process of the organic light emitting layer 005 of the display panel 000, while the width of the non-display region NA is smaller to implement a narrow frame design, the retaining wall B is often closer to the display region AA, so that when the organic light emitting layer 005 is manufactured, the organic light emitting material is easily evaporated to the region of the side of the retaining wall B away from the display area AA, that is, the organic light emitting material is easily evaporated to the region of the second groove 1032, thereby affecting the narrow frame design. Therefore, in the present embodiment, the second groove 1032 that is narrow at the top and wide at the bottom is disposed on the side of the retaining wall B away from the display area AA, even if the width of the non-display area NA is small, the retaining wall B is closer to the display area AA, the over-etching design of the inner diameter D1 of the first cavity 1032A of the second groove 1032 is also able to be used, so that the area where the second groove 1032 is located in the design cannot be subjected to evaporation plating of the organic light emitting material, and thus the evaporation plating layer of the organic light emitting material can be effectively isolated in the area, thereby avoiding the organic light emitting material from being evaporated in the area where the second groove 1032 is located, which is beneficial to better realizing the narrow frame effect, and can also ensure the production yield of the display panel.

The thin film encapsulation layer 007 is used for blocking moisture and oxygen, and prevents the organic light emitting device from being corroded by the moisture and the oxygen to cause failure of the organic light emitting device. The film encapsulation layer 007 and the first inorganic layer 0010 of the present embodiment may be formed on one side of the first substrate 101 by a CVD (Chemical Vapor Deposition) process at the bottom of the second groove 1032, and due to the design of the larger inner diameter D1 of the first cavity 1032A of the second groove 1032, the film encapsulation layer 007 and the first inorganic layer 0010 formed by the CVD process may be at least in contact with the sidewall 10320 of the second groove 1032, that is, the multiple inorganic intrusion structures of the first inorganic encapsulation layer 007A, the second inorganic encapsulation layer 007C, and the first inorganic layer 0010 of the film encapsulation layer 007 are formed on the sidewall 10320 of the second groove 1032, which is beneficial to better blocking water Vapor and improving the manufacturing yield of the display panel.
