Method for coating polyimide on liquid crystal display panel

摘要

A method for coating polyimide on liquid crystal display panel includes: (1) providing nozzles and a glass substrate; (2) tightly and regularly juxtaposing the nozzles in a row so that the row has a length that corresponds to width of the glass substrate; (3) vertically positioning the entire row above the glass substrate so as to correspond to the glass substrate along the width of the glass substrate; (4) simultaneously activating the nozzles to allow each of the nozzles to simultaneously drip down polyimide solution according to predetermined flow rate, while moving the glass substrate so as to have the polyimide solution uniformly applied to the glass substrate form a polyimide film; and (5) using a doctor blade to shape the polyimide film that is uniformly coated on the glass substrate so as to provide a regular and flat surface of the polyimide film on the glass substrate.

1. A method for coating polyimide on a liquid crystal display panel, comprising the following steps:
(1) providing a plurality of cylindrical nozzles and a glass substrate; (2) arranging the plurality of cylindrical nozzles closely side by side in a row so that the row of nozzles has a length that corresponds to a width of the glass substrate; (3) vertically positioning the entire row of the nozzles above the glass substrate so as to correspond to the glass substrate along the width of the glass substrate; (4) simultaneously activating the plurality of nozzles to allow each of the nozzles to simultaneously drip down polyimide solution according to a predetermined flow rate, while moving the glass substrate so as to have the polyimide solution uniformly applied to the glass substrate to form a polyimide film; and (5) using a doctor blade to shape the polyimide film that is uniformly coated on the glass substrate so as to provide a substantially flat surface of the polyimide film on the glass substrate.
