Apparatus for manufacturing display device and method of manufacturing display device

An apparatus for manufacturing a display device, the apparatus comprising:

• a plurality of droplet ejection units, each comprising a nozzle for ejecting droplets;
• a detection unit arranged on a fall path of a plurality of droplets falling from the plurality of droplet ejection units and configured to detect low-resolution data comprising a shape of the plurality of droplets;
• and
• a control unit configured to determine a volume of each of the plurality of droplets based on the detected low-resolution data, the control unit comprising:
• a machine learning unit configured to perform machine learning to determine a correlation between sample low-resolution data and sample high-resolution data, the sample low-resolution data comprising a shape of a plurality of sample low-resolution droplets, the sample high-resolution data comprising a shape of high-resolution droplets corresponding to each of the plurality of sample low-resolution droplets input to the machine learning unit;
• and
• a volume extraction unit configured to determine a volume of the plurality of droplets by upscaling the detected low-resolution data into upscaled high-resolution data based a result of learning by the machine learning unit, and
• wherein the sample high-resolution data has a magnification greater than a magnification of the sample low-resolution data.
