Abstract

A liquid discharge method is a method for depositing liquid on a plurality of target discharge partitioned areas formed on a substrate as the liquid is selectively discharged from a plurality of discharge nozzles while the substrate and the discharge nozzles are moved relative to each other. The liquid discharge method includes setting an arrangement pattern according to shapes and positions of the target discharge partitioned areas so that a number of the discharge nozzles selected to be used among the discharge nozzles capable of depositing the liquid in the target discharge partitioned areas is the same in each discharge timing.

Claims (20)

1. A liquid discharge method for depositing a liquid on a plurality of target discharge partitioned areas formed on a substrate as the liquid is selectively discharged from a plurality of discharge nozzles while the substrate and the discharge nozzles are moved relative to each other, the liquid discharge method comprising:

generating an arrangement map indicating selected positions of the target discharge partitioned areas in which the liquid is to be deposited, the selected positions being selected according to shapes and positions of the target discharge partitioned areas so that a number of the discharge nozzles selected to be used among the discharge nozzles capable of depositing the liquid in the target discharge partitioned areas is the same in each discharge timing.

2. The liquid discharge method according to claim 1 , wherein

the generating of the arrangement map includes generating the arrangement map so that the number of the discharge nozzles selected to be used in each discharge timing to deposit the liquid in one of the target discharge partitioned areas is set to a predetermined number.

3. The liquid discharge method according to claim 1 , wherein

the generating of the arrangement map includes generating the arrangement map so that a number of discharge cycles of each of the discharge nozzles selected to be used to deposit the liquid in one of the target discharge partitioned areas is the same.

4. The liquid discharge method according to claim 1 , wherein

the generating of the arrangement map includes generating the arrangement map so that a discharge interval of each of the discharge nozzles selected to be used to deposit the liquid in one of the target discharge partitioned areas is equivalent to a minimum value of an interval of the discharge timing.

5. The liquid discharge method according to claim 1 , wherein

the generating of the arrangement map includes generating the arrangement map so that a shape obtained by connecting an outermost periphery of landing positions of the liquid within one of the target discharge partitioned areas has a maximum surface area.

6. The liquid discharge method according to claim 1 , wherein

the generating of the arrangement map includes generating the arrangement map so that a shape obtained by connecting an outermost periphery of landing positions of the liquid within one of the target discharge partitioned areas has a minimum surface area.

7. The liquid discharge method according to claim 1 , wherein

the generating of the arrangement map includes generating the arrangement map so that a maximum number of the discharge nozzles is selected to be used to deposit the liquid within one of the target discharge partitioned areas.

8. The liquid discharge method according to claim 1 , wherein

the generating of the arrangement map includes generating the arrangement map so that a minimum number of the discharge nozzles is selected to be used to deposit the liquid within one of the target discharge partitioned areas.

9. The liquid discharge method according to claim 7 , wherein

the generating of the arrangement map includes generating the arrangement map so that the discharge nozzles arranged adjacent to each other are selected to deposit the liquid within the one of the target discharge partitioned areas.

10. The liquid discharge method according to claim 8 , wherein

the generating of the arrangement map includes generating the arrangement map so that the discharge nozzles arranged adjacent to each other are selected to deposit the liquid within the one of the target discharge partitioned areas.
