Abstract:
1. A droplet discharge device, comprising: a head driven to discharge a functional liquid as a droplet; a driving voltage generation unit that generates a driving voltage to drive the head; a first temperature acquisition unit configured to acquire a temperature of the functional liquid in the head as a first temperature in a case where the head is in a head waiting state in which the head is waited; a second temperature acquisition unit configured to acquire a temperature of the functional liquid in the head as a second temperature in a case where the head is in a head driven state in which the head is driven; a temperature difference computing unit configured to compute a temperature difference between the first temperature and the second temperature; a driving voltage correction unit configured to correct the driving voltage based on the temperature difference, wherein the driving voltage generation unit is configured to generate the corrected driving voltage to the head in a case where the head is in the head driven state.
