As shown in fig. 1a and 1b, the contact area between the first binding layer 102 and the binding terminal 401 is small in the prior art, which affects the contact conductivity between the first binding layer 102 and the binding terminal 401, and thus gray-scale dark lines are easily caused, so that the process yield is reduced. In addition, before the binding member 40 is manufactured, the first side surface S1 of the display panel needs to be ground to enhance the stability of the binding member 40, but other materials cover a part of the cross section of the first binding layer 102 during grinding, so that the exposed area of the first binding layer 102 is further reduced, and further the contact resistance is large and the contact conductivity is poor.
As shown in fig. 2, which is a top view of the display panel provided in the embodiment of the present invention, the display panel 100 includes a display area A1 and a frame area A2 disposed around the display area A1, and in order to implement a full-screen, the display panel 100 provided in the embodiment of the present invention is bound by using a side binding process.
Specifically, as shown in fig. 3, fig. 4base:Sub>A and fig. 4b, which arebase:Sub>A first cross-sectional view of the display panel of fig. 2 alongbase:Sub>A directionbase:Sub>A-base:Sub>A' andbase:Sub>A side view of fig. 3, respectively, the display panel 100 includes an array substrate 10,base:Sub>A color filter substrate 20,base:Sub>A conductive connector 30 andbase:Sub>A binding member 40; the array substrate 10 includes a first binding layer 102; the color film substrate 20 is arranged opposite to the array substrate 10, the color film substrate 20 includes a conductive member 2 arranged close to the first side S1 of the display panel 100, and the conductive member 2 includes a second binding layer 202; the second binding layer 202 is electrically connected to the first binding layer 102 through the conductive connection 30; the binding member 40 is located on the first side S1, the binding member 40 being in contact with the first binding layer 102 and the second binding layer 202.

It is understood that, as shown in fig. 1a, 1b, the contact area S = t1 × L at the prior art binding; t1 is the thickness of the first binding layer 102 in the light-emitting side direction of the display panel 100, and L is the width of the binding terminal 401 in the direction perpendicular to the light-emitting side direction of the display panel 100; and the contact area S1= t1 × L + t2 × L at the binding of the present invention; t2 is the thickness of the second bonding layer 202 in the light-emitting side direction of the display panel 100; s1> S, i.e. the contact area at the binding is indeed increased.
It should be noted that, only the conductive member 2 includes one second binding layer 202 in fig. 3 as an example, in the light-emitting side direction of the display panel 100, the thickness t2 of the second binding layer 202 is greater than the thickness t1 of the first binding layer 102, so that a larger contact area with the binding member 40 can be provided. Specifically, the second binding layer 202 with a larger thickness may be manufactured by a single thick coating process or by stacking a plurality of thin coating processes to increase the thickness.
It should be noted that the conductive member 2 is located on the color film substrate 20 in the frame area A2, that is, the second bonding layer 202 is not disposed in a whole layer, but is disposed only in the frame area A2 close to the first side S1 of the display panel 100, and the second bonding layer 202 may be patterned by using a photomask process, which specifically includes the following steps: the process includes forming a film (physical vapor deposition or chemical vapor deposition), coating a photoresist, exposing, developing, etching, and stripping the photoresist, which is a conventional process for manufacturing the display panel 100, and is not described in detail herein, and other processes capable of ensuring the manufacturing accuracy may also be used to manufacture the second binding layer 202.

Both the first trace 1021 and the second trace 2021 in fig. 4a are covered by the binding terminal 401.
It should be noted that the array substrate 10 includes a first gate layer, a second gate layer, and a source/drain metal layer, which are not shown in the drawings, and the first binding layer 102 and any one of the first gate layer, the second gate layer, and the source/drain metal layer are manufactured in the same process. The first trace 1021 can be a gate line, a data line or other signal lines, the second trace 2021 is disposed corresponding to the first trace 1021, and when the conductive member 2 only includes one second bonding layer 202, one bonding terminal 401 is in contact with one corresponding first trace 1021 and one corresponding second trace 2021.
In an embodiment, an orthogonal projection of an adjacent first trace 1021 and an adjacent second trace 2021 on the first side S1 is located within an orthogonal projection of an adjacent binding terminal 401 on the first side S1.
It can be understood that, in the present embodiment, an orthographic projection area of the binding terminal 401 on the first side S1 is greater than a sum of orthographic projection areas of the first trace 1021 and the second trace 2021 on the first side S1, and in a direction perpendicular to the light-emitting side of the display panel 100, a width L of the binding terminal 401 is greater than or equal to a width of the first trace 1021 and the second trace 2021, so as to ensure that the binding terminal 401 is in sufficient contact with the first trace 1021 and the second trace 2021.
In an embodiment, the display panel 100 includes a frame adhesive layer 50, the frame adhesive layer 50 is located between the array substrate 10 and the color filter substrate 20, the frame adhesive layer 50 includes a first frame adhesive portion 501 and a second frame adhesive portion 502, the first frame adhesive portion 501 is located between one adjacent second trace 2021 and one adjacent first trace 1021, and the second frame adhesive portion 502 is located between two adjacent first frame adhesive portions 501; the conductive connecting element 30 is located in the first frame adhesive portion 501, and the adjacent second trace 2021 is electrically connected to the first trace 1021 through the conductive connecting element 30.
It can be understood that the adjacent first traces 1021 are insulated from each other, and the adjacent second traces 2021 are also insulated from each other, so that only the conductive connecting element 30 is disposed in the first frame adhesive part 501 between the adjacent first traces 1021 and the adjacent second traces 2021, and the conductive connecting element 30 is not disposed in the second frame adhesive part 502 between two adjacent first frame adhesive parts 501.
In one embodiment, the conductive connecting element 30 is a conductive particle 301, and a particle diameter d of the conductive particle 301 is greater than or equal to a distance m between an adjacent second trace 2021 and the first trace 1021. Specifically, the conductive particles 301 are conductive gold balls, and the diameter of the conductive gold balls is larger than or equal to the distance m between the first trace 1021 and the second trace 2021, so that the conductive gold balls can contact the first trace 1021 and the second trace 2021 at the same time, and the second trace 2021 can be conducted with the first trace 1021.
It should be noted that the conductive gold balls may be formed on the first trace 1021 on the array substrate 10 side, and then aligned with the second trace 2021 on the color filter substrate 20 side, or the conductive gold balls may be formed on the second trace 2021 on the color filter substrate 20 side, and then aligned with the first trace 1021 on the array substrate 10 side. The display panel 100 of the invention has higher requirement on the precision of box forming, and can adopt a vacuum pairing machine to carry out pairing, the precision of the center pairing can reach +/-1 micron, and the precision of the periphery pairing can reach +/-3 microns.
In one embodiment, in the light-emitting side direction of the display panel 100, the thickness h1 of the first frame rubber part 501 is smaller than the thickness h2 of the second frame rubber part 502.
It can be understood that, since the second trace 2021 is disposed on the upper side of the first frame adhesive part 501, the first trace 1021 is disposed on the lower side of the first frame adhesive part 501, the second trace 2021 is not disposed on the upper side of the second frame adhesive part 502, and the first trace 1021 is not disposed on the lower side of the second frame adhesive part 502, in order to seal the liquid crystal molecule layer 60 between the array substrate 10 and the color film substrate 20, the thickness of the second frame adhesive part 502 is set to be greater than that of the first frame adhesive part 501.
Specifically, as shown in fig. 3, the conductive member 2 is located on a side of the liquid crystal molecular layer 60 close to the first side S1 of the display panel 100, that is, the thickness of the conductive member 2 does not affect the thickness of the color film substrate 20, which does not cause the thickness of the entire display panel 100 to become thicker, and correspondingly, the particle diameter d of the conductive particles 301 may be set to be smaller than the thickness of the liquid crystal molecular layer 60, thereby saving the production cost.
In one embodiment, the electron-loss capability of the second binding layer 202 is less than the electron-loss capability of the first binding layer 102.
It should be noted that, the first binding layer 102 on the side of the array substrate 10 in the prior art is usually made of titanium-aluminum-titanium, and the metal film layer with the largest cross-sectional area on the first side S1 is aluminum, and the aluminum is easily oxidized and loses conductivity. In the embodiment, the second binding layer 202 is made of a material with a weak electron losing capability, so that the second binding layer is not easily oxidized, and the contact conductivity at the binding position is improved. Specifically, the second binding layer 202 may be made of a material with a strong oxidation resistance, such as gold, copper, molybdenum, titanium, or indium tin oxide.
In the prior art, when the first bonding layer 102 is only disposed on the array substrate 10 side, if the polishing direction is from bottom to top, the first bonding layer 102 may be peeled off from the array substrate 10. According to the invention, the second binding layer 202 is arranged on the side of the color film substrate 20, when the grinding direction is from bottom to top, the second binding layer 202 is more tightly attached to the color film substrate 20, and the peeling cannot occur; when the polishing direction is from top to bottom, the first binding layer 102 and the array substrate 10 are attached to each other more tightly, and no peeling occurs, so that the influence of the polishing direction does not need to be considered.
In an embodiment, the display panel 100 further includes an upper polarizer 80 and a lower polarizer 70, the array substrate 10 further includes a first substrate 101, and the color filter substrate 20 further includes a second substrate 201.

It is understood that, in the present embodiment, the conductive member 2 includes a plurality of second bonding layers 202 as an example, a contact area S2= t1 × L + t3 × n × L at the bonding position of the present embodiment, n is the number of layers of the second bonding layers 202, and n =3 in fig. 5. In fig. 5, only the conductive member 2 includes 3 second binding layers 202 as an example, and the actual number of the manufacturing layers n is related to the thickness t3 of the second binding layers 202, the thickness of the passivation layer 203, and the thickness of the liquid crystal molecular layer 60. By adopting the scheme of the embodiment, the conductivity can be further improved.
In one embodiment, in the light exiting side direction of the display panel 100, the thickness t3 of the second bonding layer 202 is greater than or equal to 0.5 micrometers and less than or equal to 1 micrometer.
