Claims20
A method of making barrier ribs for a display panel comprising:
- providing a transfer sheet and a mold having a microstructured surface suitable for making barrier ribs;
- disposing a template having at least one opening on the transfer sheet;
- dispensing a curable inorganic paste in at least each opening;
- removing the template forming at least one discrete coating of inorganic paste;
- contacting an exposed surface of the coating to a glass substrate and removing the transfer sheet such that the discrete coating of inorganic paste is transferred onto the glass substrate;
- contacting the discrete coating of inorganic paste with the mold such that inorganic paste is disposed between the microstructured surface of the mold and the glass substrate;
- and
- curing the inorganic paste.
