Methods of forming liquid display panels and the like wherein using two-component epoxy sealant
Liquid crystal display (LCD ) panels can be formed rapidly by this method, which involves depositing liquid crystal (LC) in a central region of one substrate, depositing a fillet of epoxy material in a continuous loop along the periphery of one substrate to surround the LC material, placing a second...

| description | Liquid crystal display (LCD ) panels can be formed rapidly by this method, which involves depositing liquid crystal (LC) in a central region of one substrate, depositing a fillet of epoxy material in a continuous loop along the periphery of one substrate to surround the LC material, placing a second glass substrate over the first substrate and in continuous contact with the epoxy fillet, and then causing the fillet to set by curing or cross-linking. Advantageously, the epoxy fillet can be hardened by scanning it with an infrared or ultraviolet laser focussed to avoid heating the LC material. Alternatively, the epoxy fillet can be formed from two-component epoxy by depositing one fillet of each component on the peripheral region of one of the substrates, joining the substrates to merge the two components, and then vibrating the joined substrates to enhance commingling and setting of the two components into a strong hermetic seal. |
