Functional droplet coating apparatus, display, and electronic device

A functional droplet coating apparatus comprising:

• a functional droplet discharge head for discharging a plurality of functional droplets;
• a stage for setting thereon a board to be coated with the functional droplets discharged from the functional droplet discharge head;
• a drying unit for covering one or entire part of the board set on the stage, the drying unit for drying the functional droplets ejected from the functional droplet discharge head, the drying unit includes a decompression drying function, the drying unit selectively sealingly engaging the board, the drying unit and the board forming a decompression chamber in the drying process;
• a controller determining an elapsed time after the discharging of the functional droplets and comparing the elapsed time to a blotching prevention time, the controller moving the stage and board from the functional droplet discharge head to the drying unit at or before the elapsed time reaches a blotching prevention time.
