Abstract: An apparatus for manufacturing a display device includes: droplet ejection units for ejecting droplets; a detection unit arranged on a fall path of the droplets and configured to detect low-resolution data of droplets; and a control unit configured to determine a volume of each of the droplets based on the detected low-resolution data. The control unit includes: a machine learning unit configured to perform machine learning to determine a correlation between sample low-resolution data and sample high-resolution data of droplets; and a volume extraction unit configured to determine a volume of the falling droplets by upscaling the detected low-resolution data into upscaled high-resolution data based a result of learning by the machine learning unit. The sample high-resolution data has a magnification greater than a magnification of the sample low-resolution data.
