Abstract: A thin film forming apparatus comprises a first storage unit, a first nozzle unit, a first light-irradiating unit, a second storage unit, a second nozzle unit, and a second light-irradiating unit. The first storage unit is configured to store a first organic material. The first nozzle unit is connected to the first storage unit and is configured to spray the first organic material stored in the first storage unit. The first light-irradiating unit is disposed adjacent to the first nozzle unit and is configured to irradiate light having a wavelength that cures the first organic material. The second storage unit is configured to store a second organic material. The second nozzle unit is disposed adjacent to the first nozzle unit, is connected to the second storage unit, and is configured to spray the second organic material stored in the second storage unit. The second light-irradiating unit is disposed adjacent to the second nozzle unit and is configured to irradiate light having a wavelength that cures the second organic material.

Abstract: An inkjet print apparatus includes a print head discharging ink onto a substrate, the print head including a first heater; a reservoir storing the ink; a first pipe supplying the ink to the reservoir; a second pipe collecting surplus ink; a mixing unit located on the first pipe and mixing the ink; a pump located on the second pipe and pressurizing and supplying the surplus ink to the reservoir; a temperature sensor located between the mixing unit and the print head and sensing a temperature of the ink; and a controller controlling a temperature of at least one of the first heater and the second heater in response to information received from the temperature sensor. The print head includes a heat insulator blocking heat emitted from the first heater between the substrate and the first heater.
