Solution spray apparatus and solution spray method
View Patent ↗A solution spray apparatus includes a nozzle which sprays a droplet of a solution such as EL solution, a heater is provided on the nozzle to heat the solution in the nozzle to a temperature lower than a boiling point of the solution in the nozzle, so that the droplet of the heated solution is ejected from the spray to an object.
1. A solution spray apparatus comprising:
at least one nozzle which sprays at least one droplet of a respective solution; and
a heater which heats the solution in the at least one nozzle to a temperature lower than a boiling point of the solution,
wherein the solution comprises an EL solution; and
wherein said at least one nozzle comprises a first nozzle which sprays a first solution containing an EL material for emitting light in a first color, and a second nozzle which sprays a second solution containing an EL material for emitting light in a second color different from the first color.
2. The apparatus according to claim 1 , wherein the heater is controlled to set the first solution and the second solution to different temperatures.
