Abstract
The present invention discloses a film coating device that includes an ink sprayer, a holder, and a heater. The holder is used to hold a substrate to be coated a film. The ink sprayer sprays film material on the substrate with a preset spraying quantity and stepping rate. The heater heats the film material to a predetermined temperature range during the film spraying process in order to decrease a surface tension difference of the film material. The present invention also discloses a film coating method using the film coating device.
