A practical approach to processing flexible displays

Abstract— The materials and fabrication aspects of flexible displays will be reviewed. The fabrication of flexible displays requires the consideration of proper material selection, handling of plastic‐film substrates, and a low‐temperature process for the fabrication of active‐matrix devices on plastic substrate. In addition, for the low‐cost fabrication approach, direct printing of active‐matrix patterning without a photolithography process is also required. Before commercial‐level production of flexible displays is considered, the factors of product reliability and practical value are considered. Samsung LCD Division's approach to the fabrication of flexible displays and future plans to develop a practical method that will lead to the production level of flexible displays will also be described.
