INSPECTION METHOD FOR DISPLAY PANEL

摘要

Disclosed herein is an inspection method for a display panel according to the present embodiments comprising 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; and if the second particle brightness level is higher than the first particle brightness level, determining the particle region to be an internal particle.

1. An inspection method for a display panel, comprising:
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; comparing the first and second particle brightness levels to each other; and determining the particle region to be an internal particle when the second particle brightness level is higher than the first particle brightness level.
