Abstract: The present disclosure relates to a backlight frame including a frame body, which has a first and a second side wall opposite to each other, and a third and a fourth side wall opposite to each other, wherein at least one first protrusion is arranged in the frame body close to the first side wall, at least one second protrusion is arranged wall in the frame body close to the second side, at least one third protrusion is arranged in the frame body close to the third side wall, and at least one fourth protrusion is arranged in the frame body close to the fourth side wall. The first, second, third and fourth protrusions together define a placement area for disposing a light guide plate. Through a placement area with a regular shape for disposing the light guide plate cut in a regular manner therein, the utilization of raw material for the light guide plate to be cut can be effectively improved, and the production cost of the light guide plate can be finally reduced.

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.
