Abstract

A method of manufacturing an integrated circuit (IC) for driving a flexible display includes depositing a pattern of spatially non-repetitive features in a first layer on a flexible substrate, said pattern of spatially non-repetitive features not substantially regularly repeating in both of two orthogonal directions (x,y) in the plane of the substrate; depositing a pattern of spatially repetitive features in a second layer on said first layer; aligning said second layer and said first layer so as to allow electrical coupling between said non-repetitive features and said repetitive features, wherein distortion compensation is applied during deposition of said repetitive features to enable said alignment.
