the direct cause and the root cause of display inconformity were found
and on this basis
experiments were designed to improve the display inconformity defect. The analysis indicated that the direct cause of display inconformity was the position shift of pillar spacer caused by gravity; and the root cause was that the size of pillar spacer was too small
so there was no metal line around the pillar spacer which could prevent the pillar spacer from position shift. The result of experiments showed that transport panel by putting it in box
or reducing the duration while panel was put in cassette could obviously improve display inconformity
but were not suitable for production. Furthermore
increasing the size of pillar spacer
so as to decrease the space around pillar spacer could effectively improve the display inconformity defect at the source. By increasing the size of pillar spacer from 15 m to 23 m
the defect grade of display inconformity was reduced from Level 4 to Level 2.5
and the display inconformity defect was greatly improved.
