We describe experimental results comparing the use of pulsed ultraviolet lasers with ultraviolet lamps for assembling liquid crystal panels. Pull tests were also made to obtain data regarding the total fluence needed for UV lasers vs UV lamps. We found that the UV lasers are more efficient and the short UV laser pulses are advantageous in that heating of the liquid crystal is kept at a minimum due to the short pulse widths. Experimental data also showed that laser pulses lead to less shadowing of the portions of the panel that are shielded from the radiation that causes photoinititors to bring about polymerization of the glue seal.
