Abstract
A droplet discharge device includes a head for discharging a functional liquid, a driving voltage generation unit for generating a driving voltage to drive the head, first and second temperature acquisition units, a temperature difference computing unit, and a driving voltage correction unit. The first and second temperature acquisition units are configured to acquire temperature of the functional liquid in the head as first and second temperatures, respectively, when the head is in a head waiting state and in a head driven state, respectively. The temperature difference computing unit is configured to compute a temperature difference between the first and second temperatures. The driving voltage correction unit is configured to correct the driving voltage based on the temperature difference. The driving voltage generation unit is configured to generate the corrected driving voltage to the head when the head is in the head driven state.
