Study of Polyimide on Improvement of Crushed Bright Spot Mura on FFS Display

Description:

In FFS displays, if the photolysis product of polyimide remains, it can cause light leakage in dark state of the panel, which is called crushed bright spot mura.In this work, we designed the polyimide structure, optimized the exposure dose of the ultraviolet intensity, and enhanced the baking time and temperature after ultraviolet treatment, and by the three strategy the issue achieved great improvement.
