Abstract:
A method for continuously forming an orientation layer on sequentially introduced liquid crystal display panels, comprising the steps of:introducing a quantity of polyimide solution onto a rotating anilox roll;compressing by contacting an exterior surface of the rotating anilox roll to a doctor roll positioned adjacent thereto to compress the anilox roll;contacting the surface of the anilox roll to an APR resin plate attached to an underlying rotatable transfer cylinder to deliver a predetermined amount of the polyimide solution to the APR resin plate, wherein the APR resin plate includes at least one polyimide (PI) pattern portion corresponding to an effective screen area of the liquid crystal display having a material of a first hardness and at least one polyimide (PI) pattern edge portion corresponding to a non-effective screen area of the liquid crystal display having a material of a second hardness, and wherein the second hardness is greater than the first hardness;positioning a liquid crystal display panel surface to underlay the APR resin plate; andprinting a pattern of polyimide solution on the underlying liquid crystal display panel surface, said printing step comprising contacting pattern portions of the APR resin plate to the desired liquid crystal display panel surface.
