摘要： An inspection method for a display panel according to the present invention comprises the steps of: driving the display panel so as to display a first color having a first reference brightness level; photographing the display panel to obtain a first image including at least one particle region; deriving a first particle brightness level of the particle region contrasted to the first reference brightness level from the first image; driving the display panel so as to display a second color having a second reference brightness level higher than the first reference brightness level; photographing the display panel to obtain a second image containing the particle region; deriving a second particle brightness level of the particle region contrasted to the second reference brightness level from the second image; and if the second particle brightness level is higher than the first particle brightness level, determining the particle region to be an internal particle.
