Development of Ch-LC microencapsulated flexible displays with reduced driving voltage and much simplified manufacturing process

Abstract

We developed a novel Ch-LC microencapsulated flexible display with the characteristics of the reduced driving voltage and much simplified manufacturing process. The driving voltage of Ch-LC microencapsulated displays was drastically reduced by adopting the following two principal ways: 1) lowering the anchoring energy between liquid crystals and shell polymers, 2) optimizing the size of LC microcapsules and thickness of LC microcapsule-coated layer. And the fabrication processes was greatly simplified by taking advantage of both coating method using a bar coater and direct printing of opposite electrode using a screen print. ⓒ 2013 ITE and SID.
