preparation example Construction

[0041] The preparation method of the above-mentioned capacitive screen includes the following steps:

[0042] a. Cover the base material with a conductive film for making capacitor via units, and print transparent insulating ink on the conductive film to protect the patterns that need to be preserved;

[0043] b. Use etching solution, etching gas, corona or other chemicals to remove the exposed conductive material on the conductive film;

[0044] c. Print silver paste on the base material or use copper plating process to make edge line layout to complete the capacitive access unit of the entire emission layer;

[0045] d. Repeat steps a to c to make the capacitive access unit of the receiving layer;

[0046] e. Use OCA optical glue or water glue to bond the emitting layer and the receiving layer to make a touch film;

[0047] f. Use ACF or solder to weld the flexible circuit board to the laminated touch film;

[0048] g. Connect the flexible circuit board to the touch main ...
