Abstract

An apparatus and a method for rapid monitoring of inkjet ink droplets using time delay integration are proposed. Inkjet ink droplets used in manufacturing a display panel may be captured for a set period of time using a wide one-dimensional (1D) line scan camera to obtain a plurality of pieces of high-resolution small-amount image data. The obtained plurality of pieces of high-resolution small-amount image data may be subjected to image processing to generate ink droplet two-dimensional (2D) time-space information. The ink droplet two-dimensional (2D) time-space information may be compared with pre-stored reference ink droplet 2D time-space information to determine whether the ink droplets are normal.
