[0055] Specifically, the first substrate 100 and the second substrate 200 may be aligned and assembled into a panel box, and then the ink 300 may be injected into the space inside the panel box.

[0056] Specifically, the edge portions of the panel box or the first substrate 100 and the second substrate 200 may be sealed by using a sealant.

[0057] In step S500 , a voltage is provided to the plurality of first electrodes 102 and the plurality of second electrodes 103 , wherein the voltage of the first electrodes 102 has an opposite polarity to the voltage of the second electrodes 103 .

[0058] Specifically, as shown in FIG3 , voltages are provided to the plurality of first electrodes 102 and the plurality of second electrodes 103 , wherein the voltage of the first electrode 102 has an opposite polarity to the voltage of the second electrode 103 , so that charged particles gather on the first electrode 102 and the second electrode 103 .

[0059] Specifically, as shown in FIG3 , for example, when a negative voltage is applied to the first electrode 102 , positively charged particles 301 gather on the first electrode 102 ; and when a positive voltage is applied to the second electrode 103 , negatively charged particles 302 gather on the second electrode 103 .

When the display device is irradiated with ultraviolet light UV, the charged particles 312 are not in the path of the ultraviolet light UV.

The black charged particles and the white charged particles will absorb or reflect the ultraviolet light and other light that cause polymerization reactions in the path of the ultraviolet light and other light that cause polymerization reactions, making it difficult for these light rays to reach the first substrate 100, and making it difficult for the generated polymer retaining wall to be well connected between the first substrate 100 and the second substrate 200; while by adopting the improved solution of the present application, the charged particles 312 are not in the path of the ultraviolet light and other light that cause polymerization reactions, and the ultraviolet light and other light that cause the polymer monomers 303 to cure or polymerize can pass through the ink 300 to reach the first substrate 100, and the polymer monomers 303 can fully undergo polymerization and curing reactions between the first substrate 100 and the second substrate 200, thereby generating a retaining wall 3031 with good performance connected to the first substrate 100 and the second substrate 200.

[0066] In some embodiments, when voltages are provided to the plurality of first electrodes 102 and the plurality of second electrodes 103 , the method further includes: providing a voltage to the third electrode 202 , wherein the voltage of the third electrode 202 is between the voltage of the first electrode 102 and the voltage of the second electrode 103 .

[0067] Specifically, for example, the voltages of the multiple first electrodes 102 and the multiple second electrodes 103 are +15V and -15V respectively, and the voltage of the third electrode 202 is 0V; for example, the voltages of the multiple first electrodes 102 and the multiple second electrodes 103 are +17V and -13V respectively, and the voltage of the third electrode 202 is 2V.

[0068] Specifically, the voltage of the third electrode 202 is between the voltage of the first electrode 102 and the voltage of the second electrode 103 , so that the charged particles 312 are gathered on the first electrode 102 and the second electrode 103 instead of on the third electrode 202 .
