Low-Cost Displays—Semiconductor and Lithographic Performance Requirements

The field of low-cost flexible displays has attracted an enormous amount of interest in the past few years. This paper analyzes the challenges associated with designing a backplane for an electrophoretic front plane and develops a general model which relates semiconductor and lithographic performance metrics to display qualities such as speed, uniformity, and resolution. Specific examples are given for all ink-jet printed displays as well as for partially or all photolithographically patterned displays.
