electrically connecting a plurality of light emitting elements to the data lines through a second conductive member to form a plurality of light emitting cells;
the second conductive member is prepared by coating a conductive material on a steel mesh and then curing, and a plurality of second conductive members are formed on the data lines correspondingly.
6. The method of claim 5, wherein the first conductive member and the second conductive member are formed by applying a conductive material to the same steel mesh and then curing the applied conductive material.
7. The method as claimed in claim 6, wherein a plurality of meshes are spaced at positions of the steel mesh corresponding to the partition regions, and any one of the meshes is coated with a conductive material and then cured to form the first conductive member.
8. The method of manufacturing a display panel according to any one of claims 5 to 7, wherein the first conductive member and/or the second conductive member is manufactured by laser engraving the cured conductive material after the conductive material is coated on the steel mesh and cured.
9. The method for manufacturing a display panel according to claim 1, wherein the step of performing a lighting test on the display panel to be tested includes:
applying a voltage required by a light emitting unit of the display panel to the plurality of second terminals of the short-circuit region;
the first conductive member conducts the short circuit area and the bonding area, and a first wiring end of the bonding area provides a corresponding electric signal for the display panel light-emitting unit;
and judging whether the backboard circuit of the display panel to be tested is normal or not according to the display of the light-emitting unit.
10. A display panel characterized by being produced by the production method for a display panel according to any one of claims 1 to 9.
