Abstract: In this paper, we conclued the bright spots at CF by PI coating were mainly caused by the following aspects. At first , we investigated the influence of the new materials , there is PI ink and APR Plate . As a result, Lower viscosity and lower molecule weight PI ink did not occurred .we analyzed that in the case of a kind of PI ink using different APR Plate , CF overcoat difference UV intensity ,Cleaning and PI coater Process parameter tunning . Optimize conditions, it can improve bright spots caused by PI coating defect for fringe field switching liquid crystal display. Afterwards, we researched the effects of different kinds of conditions. In order to verify this test result, further experiment was carried out. Optimized parameters are studied in this paper.
