Abstract
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.
