[0035] In recent years, in display panels, the circuit wires originally in the border area are placed in the display area, and the upper and lower substrates are electrically connected through electrical connection units. The main body of the electrical connection unit is usually a metal material with high conductivity. These metals are exposed to a high temperature or high humidity environment and the action of current or electric field. Water and oxygen intrusion is aggravated, and ionization, migration and diffusion will occur. As the migration of metal ions accumulates, the quality of the electrical connection unit will be degraded, voids will appear, resulting in increased resistance and performance degradation. At the same time, metal bridges are easily formed between adjacent electrical connection units, causing short circuits and damage to the display panel.

[0036] See also Figures 1 to 8 , an embodiment of the present invention provides a display panel 100, comprising:

[0037] a first substrate 110;

[0038] A second substrate 120 is disposed opposite to the first substrate 110;

[0039] a plurality of electrical connection units 200 , located between the first substrate 110 and the second substrate 120 , so as to electrically connect the first substrate 110 and the second substrate 120 ;

[0040] The first isolation layer 300 includes at least a plurality of first isolation units located between the first substrate 110 and the second substrate 120;

[0041] Wherein, a first isolation unit 310 is disposed around the electrical connection unit 200 .

[0042] The present invention surrounds the first isolation unit on the outside of the electrical connection unit, utilizes the first isolation unit to alleviate water and oxygen intrusion, and avoids ion diffusion between two adjacent electrical connection units, thereby improving the stability of the electrical connection unit, extending the service life of the electrical connection unit, and improving the display effect.

[0043] The technical solution of the present invention will now be described in conjunction with specific embodiments.

[0044] In this embodiment, please refer to Figure 1 The display panel 100 includes a first substrate 110, a second substrate 120 arranged opposite to the first substrate 110, a plurality of electrical connection units 200 located between the first substrate 110 and the second substrate 120, and a first isolation layer 300. The first isolation layer 300 at least includes a plurality of first isolation units 310 located between the first substrate 110 and the second substrate 120. The electrical connection unit 200 electrically connects the first substrate 110 and the second substrate 120. The first isolation layer 300 includes a plurality of first isolation units 310. A first isolation unit 310 is arranged around an electrical connection unit 200.

[0045] The first isolation layer 300 is arranged in contact with the electrical connection unit 200. When the first substrate 110 and the second substrate 120 are aligned and bonded, gaps are inevitably formed, which aggravates the intrusion of water and oxygen. A first isolation unit 310 is arranged on the periphery of at least one of the electrical connection units 200. The first isolation unit 310 helps to block the intrusion of water and oxygen into the electrical connection unit 200, while avoiding ion diffusion between the electrical connection unit 200 and the surrounding electrical connection units 200, thereby improving the stability of the electrical connection unit 200, extending the service life of the electrical connection unit 200, and improving the display effect.

[0046] In some embodiments, see Figure 1 The first isolation layer 300 is arranged in contact with the inorganic film layer in the first substrate 110 , and the first isolation layer 300 is arranged in contact with the inorganic film layer in the second substrate 120 .

[0047] The inorganic film layer has a good ability to block water and oxygen. The first isolation layer 300 is arranged in contact with the inorganic film layer, which further improves the first isolation layer 300's ability to cut off the water and oxygen intrusion path, improves the water and oxygen blocking ability, improves the stability of the electrical connection unit 200, extends the service life of the electrical connection unit 200, and improves the display effect.

[0048] In some embodiments, see Figure 1The first substrate 110 includes a plurality of first terminals 111, and a first terminal 111 is correspondingly connected to an electrical connection unit 200; the second substrate 120 includes: a plurality of second terminals 121, and a second terminal 121 is correspondingly connected to an electrical connection unit 200; an insulating layer 400, located on the side of the second terminal 121 away from the first substrate 110, and the insulating layer 400 includes a plurality of first openings 401, and the first openings 401 expose the second terminal 121; a wire layer 500, located in the first opening 401, and the wire layer 500 is electrically connected to the second terminal 121; a second isolation layer 600, located on the surface of the wire layer 500 close to the first substrate 110; wherein the second isolation layer 600 at least includes a plurality of second isolation units 610 arranged on the side wall of the first opening 401.

[0049] The wire layer 500 may include multiple wires, and the insulating layer 400 may include multiple film layers. At the same time, the wire layer 500 is susceptible to water and oxygen corrosion in the first opening 401 of the insulating layer 400. The second isolation unit 610 is set in the first opening 401. The second isolation unit 610 can block the water and oxygen invasion path, thereby protecting the wire layer 500. The second isolation unit 610 is used to alleviate the intrusion of water and oxygen, thereby preventing the wire layer 500 from being corroded by water and oxygen, and preventing the electrical connection unit 200 from being corroded. At the same time, ion diffusion between two adjacent wire layers 500 is avoided, thereby improving the stability of the wire layer 500, extending the service life of the wire layer 500, and improving the display effect.

[0050] In some embodiments, see Figure 2 The first substrate 110 also includes a first organic layer 700 located on the side of the insulating layer 400 close to the second substrate 120, and the first organic layer 700 includes a plurality of second openings 710 and a plurality of third openings 720; the first isolation layer 300 also includes a plurality of third isolation units 330, and the third isolation units 330 are filled in the third openings 720; wherein, the second opening 710 exposes the second terminal 121, a first opening 401 and a second opening 710 are arranged correspondingly, and the third opening 720 exposes the inorganic film layer in the insulating layer 400.

[0051] When the first organic layer 700 is added to the second substrate 120, a water and oxygen intrusion path is added on the side of the first organic layer 700 close to the insulating layer 400. By opening a third opening 720 on the first organic layer 700 and filling the third isolation unit 330 in the third opening 720, water and oxygen are further blocked from invading the electrical connection unit 200, thereby extending the service life of the electrical connection unit 200 and improving the display effect.

[0052] In some embodiments, the first isolation unit 310 and the third isolation unit 330 are integrally provided.

[0053] The first isolation unit 310 and the third isolation unit 330 are integrally arranged, which can not only improve the ability to block water and oxygen in the gap between the first substrate 110 and the second substrate 120, but also avoid ion diffusion between the surrounding electrical connection units 200, thereby improving the stability of the electrical connection unit 200, extending the service life of the electrical connection unit 200, and improving the display effect.

[0054] In some embodiments, the first isolation layer 300 is integrally formed with the inorganic film layer in contact with the first substrate 110, or the first isolation layer 300 can be integrally formed with the inorganic film layer in contact with the second substrate 120. The first isolation layer 300 comprises an inorganic material and is formed together with the inorganic film layer, which saves process steps, enhances the integrity of the water and oxygen barrier capability, further extends the service life of the electrical connection unit 200, and improves the display effect.

[0055] In some embodiments, see Figure 2 、 Figure 4 、 Figure 5 The surface area of ​​the first isolation unit 310 on the side corresponding to the third isolation unit 330 is larger than the surface area of ​​the third isolation unit 330 on the side corresponding to the first isolation unit. The location of the third opening 720 is relatively far from the electrical connection unit 200, making the opening precision easier. This achieves a water and oxygen barrier effect while reducing production costs.

[0056] In some embodiments, see Figure 6 The area of ​​the surface of the first isolation unit 310 on the side corresponding to the third isolation unit 330 is equal to the area of ​​the surface of the third isolation unit 330 on the side corresponding to the first isolation unit. Precisely positioning the third opening 720 further reduces the contact area between the first isolation layer 300 and the first organic layer 700, lowering the risk of water and oxygen intrusion, further extending the service life of the electrical connection unit 200, and improving the display effect.

[0057] In some embodiments, see Figure 1 、 Figure 2 , the second isolation unit 610 can be formed separately.

[0058] In some embodiments, the material of the second isolation unit 610 includes any one or more of SiO 2 , ZrO 2 , Al 2 O 3 , TiO 2 , Au, and Pt.

[0059] In some embodiments, see Figure 3 、 Figure 4 The insulating layer 400 includes a first inorganic layer 410, a second inorganic layer 420, and a second organic layer 430 located between the first inorganic layer 410 and the second inorganic layer 420, and the second inorganic layer 420 is located close to the second organic layer 430 and away from the first substrate 110; wherein, the second isolation unit 610 is integrally arranged with the second inorganic layer 420, and the material of the second isolation unit 610 is the same as the material of the second inorganic layer 420.

[0060] The second isolation unit 610 can be formed together with the second inorganic layer 420, which can save process steps, improve the integrity of the second inorganic layer 420, and reduce the path for water and oxygen to enter. This prevents the wire layer 500 from being corroded by water and oxygen, and thus the electrical connection unit 200 from being corroded, further blocks water and oxygen from entering the electrical connection unit 200, and simultaneously prevents ion diffusion between the electrical connection unit 200 and surrounding electrical connection units 200, thereby improving the stability of the electrical connection unit 200, extending its service life, and improving the display effect.

[0061] In some embodiments, see Figures 1 to 5 The first substrate 110 also includes the third inorganic layer 113 located on the side of the first terminal 111 close to the second substrate 120, and the third inorganic layer 113 includes a plurality of fourth openings 114, and the fourth openings 114 expose the first terminal 111, and the electrical connection unit 200 is electrically connected to the first terminal 111 through the fourth openings 114.

[0062] In some embodiments, the second isolation unit 610 only covers the gap between the first inorganic layer 410 and the first organic layer 700 in the first opening 401 , and the gap between the second inorganic layer 420 and the first organic layer 700 .

[0063] The second isolation unit 610 covers the gaps between the film layers, thereby enhancing the water and oxygen barrier capability of the entire display panel 100 , improving the stability of the electrical connection unit 200 , extending the service life of the electrical connection unit 200 , and improving the display effect.

[0064] In some embodiments, the second isolation unit 610 covers the entire sidewall of the first opening 401 .

[0065] In some embodiments, the second isolation unit 610 includes a first portion located in the first opening 401 and a second portion extending out of the first opening 401 , and the first portion is connected to the second portion.

[0066] The second portion is located between the insulating layer 400 and the wire layer 500, and can provide a better protection effect for the wire layer 500 located outside the first opening 401, thereby preventing the wire layer 500 from being corroded by water and oxygen, preventing the electrical connection unit 200 from being corroded, further blocking the invasion of water and oxygen into the electrical connection unit 200, and at the same time avoiding ion diffusion between the electrical connection unit 200 and the surrounding electrical connection units 200, thereby improving the stability of the electrical connection unit 200, extending the service life of the electrical connection unit 200, and improving the display effect.

[0067] In some embodiments, see Figure 7 、 Figure 8 The first isolation units 310 are spaced apart from each other, which can further reduce ion diffusion between the two adjacent electrical connection units 200, improve the stability of the electrical connection units 200, extend the service life of the electrical connection units 200, and improve the display effect.

[0068] In some embodiments, see Figure 8 , the width of the first isolation unit 310 gradually increases in a direction from the center of the display panel 100 to the edge of the display panel 100 .

[0069] The larger the width of the first isolation unit 310, the stronger the water and oxygen blocking ability, and the edge of the display panel 100 is more easily corroded by water and oxygen. In the direction from the center of the display panel 100 to the edge of the display panel 100, the width of the first isolation unit 310 gradually increases, which can enhance the overall water and oxygen blocking ability of the display panel 100, improve the stability of the electrical connection unit 200, extend the service life of the electrical connection unit 200, and improve the display effect.

[0070] In some embodiments, the arrangement density of the first isolation units 310 gradually increases from the center of the display panel 100 to the edge of the display panel 100 .

[0071] The first isolation unit 310 may not be provided around the electrical connection unit 200 in the center direction of the display panel 100. The first isolation unit 310 only needs to be provided on the edge of the display panel 100. This can also enhance the overall water and oxygen barrier capability of the display panel 100, improve the stability of the electrical connection unit 200, extend the service life of the electrical connection unit 200, and improve the display effect.

[0072] In some embodiments, one of the electrical connection units 200 corresponds to one of the isolation units. In the direction from the center of the display panel 100 to the edge of the display panel 100, the arrangement density of the electrical connection unit 200 increases, thereby increasing the arrangement surface density of the first isolation unit 310. This can also enhance the overall water and oxygen barrier capability of the display panel 100, improve the stability of the electrical connection unit 200, extend the service life of the electrical connection unit 200, and improve the display effect.

[0073] In some embodiments, see Figure 5 The display panel 100 further includes a flexible transparent unit 320 located between two adjacent first isolation units 310 .

[0074] A flexible transparent unit 320 is filled between the first isolation units 310 to increase the overall flexibility of the display panel 100. The flexible transparent unit 320 is made of an insulating transparent material, such as liquid optical adhesive, which is only used as an example and not specifically limited.

[0075] In some embodiments, two adjacent first isolation units 310 are disposed in contact with each other. The first isolation units 310 can be connected to form a whole surface, which simplifies the process, maximizes the water and oxygen intrusion path, and protects the display panel 100.

[0076] In some embodiments, the material of the first isolation unit 310 includes any one or more combinations of glass powder, epoxy resin, acrylate, polyurethane, and silicone.

[0077] The material of the first isolation unit 310 is a composite material with a base material having low water vapor permeability and low oxygen permeability, and a viscous fluid, which can be formed by printing, dispensing, inkjet or spraying processes, and thermal curing or UV curing.

[0078] In some embodiments, see Figures 1 to 6 The first substrate 110 includes a first main body 112 away from the third inorganic layer 113 .

[0079] In some embodiments, the first substrate 110 may be a driving substrate, and the first body 112 includes a substrate, an active layer located on the substrate, a first insulating layer located on the active layer, a gate layer located on the first insulating layer, a second insulating layer located on the gate layer, a source-drain layer located on the second insulating layer, and a third insulating layer located on the source-drain layer.

[0080] In some embodiments, the second substrate 120 may be a light-emitting substrate, further comprising a light-emitting device layer including an anode layer electrically connected to the wire layer 500 , a light-emitting material layer on the anode layer, and a cathode layer on the light-emitting material layer.

[0081] The display panel 100 also includes a pixel definition layer arranged on the same layer as the light-emitting material layer, a polarizing layer located on the light-emitting device layer, and a flexible cover plate located on the polarizing layer. The display panel 100 also includes corresponding adhesive layers located between the polarizing layer and the flexible cover plate, between the light-emitting device layer and the polarizing layer, and between the back plate and the substrate.

[0082] In some embodiments, the light-emitting device layer may include OLED (Organic Light-Emitting Diode) material, or may include Micro LED or Mini LED, which is not specifically limited here.

[0083] The present invention surrounds the electrical connection unit with a first isolation unit, utilizes the first isolation unit to alleviate water and oxygen intrusion, and avoids ion diffusion between two adjacent electrical connection units, thereby improving the stability of the electrical connection unit, extending the service life of the electrical connection unit, and improving the display effect.

[0085] The specific structure of the display panel 100 can be found in any of the above embodiments and drawings of the display panel 100 , and will not be described in detail here.

[0086] In this embodiment, the device body 20 may include a middle frame, frame glue, etc., and the display device 10 may be a display terminal such as a mobile phone, a tablet, or a television, which is not limited here.
