The photoresist is coated by a suspension coating method, the photoresist can be a positive photoresist or a negative photoresist, specifically, the first sides of the first substrates to be coated with the photoresist can be combined in the same plane to perform suspension coating on the photoresist, and the photoresist is dried after the suspension coating is completed to form the photoresist. Illustratively, referring to fig. 2(a), taking photoresist as a positive photoresist as an example, the photoresist 12 is suspended on the first side 111 of the first substrate 11 to prepare the photoresist. In other embodiments, the first side of the first substrate may be placed in the photoresist solution to stick the photoresist for multiple times, so as to coat the first side of the first substrate with the photoresist.

Specifically, if a transverse wire is a scanning wire in a substrate of the display screen, a longitudinal wire is a data wire; if the transverse conductors are data conductors and the longitudinal conductors are scanning conductors.

Illustratively, referring to fig. 2(b) and 2(c), the light-shielding region 132 and the light-transmitting region 131 are provided in the mask 13, after the light-transmitting region 131 is aligned and overlapped with the first target light-transmitting region of the first side 111, the position and the size of the light-transmitting region 131 in the mask 13 are the same as those of the first target light-transmitting region, the first side 111 of the first substrate 11 covered with the mask 13 is placed in the environment of the illumination 14, and the exposure treatment is performed, and the light source for generating the illumination 14 may be a high-pressure mercury lamp, a krypton fluoride DUV light source, or the like. In the present embodiment, the exposure method is a common photolithography exposure process, and for example, there are a contact exposure method, a proximity exposure method, and a projection exposure method.

For example, if a positive photoresist is selected in step 110, the first target light-transmitting region is located to cover the first splicing section 172.

For example, if a negative photoresist is selected in step 110, the at least one first target light-transmitting area is at least two first target light-transmitting areas, and a target light-shielding area is included between the at least two light-transmitting areas. The position of the target shading area correspondingly covers the first splicing section 172.

And step 130, after the exposure treatment is completed, performing development treatment on the first side surface of the first substrate coated with the photoresist to remove part of the photoresist.

After the remaining photoresist is removed, only the conductive material layer directly contacting with the first side surface is left on the first side surface of the first substrate, and the conductive material layer directly contacting with the first side surface is the first conductive electrode.

Illustratively, taking the positive photoresist selected in step 110 as an example, referring to fig. 2(f) and fig. 2(g), the first side 111 of the first substrate 11 on which the conductive material layer 16 is completely plated is placed in a photoresist solvent to remove the remaining photoresist islands 121 to form the first conductive electrodes 161 on the first side 111.

Illustratively, referring to fig. 5(a), a photoresist is used as a positive photoresist to prepare the photoresist 22 by suspending the photoresist on the second side 211 of the second substrate 21. In other embodiments, the second side of the second substrate may be placed in the photoresist solution for multiple times to adhere the photoresist, so as to achieve the effect of coating the photoresist on the second side of the second substrate.

Specifically, if a transverse wire is a scanning wire in a substrate of the display screen, a longitudinal wire is a data wire; if the transverse conductors are data conductors and the longitudinal conductors are scanning conductors.

For example, referring to fig. 5(b) and 5(c), the mask 23 is provided with a light-shielding region 232 and a light-transmitting region 231, after the light-transmitting region 231 is aligned and overlapped with the second target light-transmitting region of the second side 211, the position and size of the light-transmitting region 231 in the mask 23 are the same as the second target light-transmitting region, the second side 211 of the second substrate 21 covered with the mask 23 is placed in the light 24 environment, and exposure processing is performed, and the light source generating the light 24 may be a high-pressure mercury lamp, a krypton fluoride DUV light source, or the like.

Wherein the position of the target shading area comprises the second splicing section 272.

For example, taking the negative photoresist selected in step 210 as an example, referring to fig. 5(d), after the exposure is completed, the mask plate 23 is removed, and the second side 211 of the second substrate 21 is immersed downward in the developing solution 25 to dissolve the photoresist in the light shielding region, in other embodiments, the entire second side 211 of the second substrate 21 may also be immersed upward in the developing solution 5; referring to fig. 5(e), the photoresist remaining on the second side 211 of the second substrate 21 after the development is completed forms a plurality of photoresist islands 221, and the second side 211 of the second substrate 21 is exposed between the photoresist islands 221.

Illustratively, referring to fig. 5(g), the conductive material layer 26 covers both the unremoved photoresist islands 221 and the recesses 29 formed by the etching process on the second side 211. Continuing to stack the conductive material layer 26 on the second side 211 of the second substrate 21 after the etching process is completed;

step 260, the second side of the second substrate is immersed in the photoresist solvent to remove the remaining photoresist, so as to form at least one second conductive electrode embedded in the groove on the second side of the second substrate.

In this embodiment, if a positive photoresist is selected in step 210, the developing solution in this step is a positive photoresist solvent, and the photoresist outside the second target light-transmitting region can be removed by the photoresist solvent; if a negative photoresist is selected in step 210, the developing solution in this step is a negative photoresist solvent, and the photoresist with at least two second target light-transmitting areas with changed chemical properties can be removed by the negative photoresist solvent. And after removing the residual photoresist, only the conductive material layer is left in the groove on the second side surface of the second substrate, and the residual conductive material layer in the groove is the second conductive electrode.
