Liquid Crystals for Superior Electro-Optic Performance Display Device with Power-Saving Mode

An advantageous factor for the technology of displays is low power consumption. For power-saving, low-frequency driving of liquid crystal displays (LCDs) is useful. However, an unacceptable performance drop, from image-flickering, occurs due to occurrence of the flexoelectric effect. Here, based on close agreement between experimental and simulated results, a new electro-optic mode with optimization of both electrode structures and physical properties of the liquid crystal materials is demonstrated. Although the calculated electro-optic properties are obtained for particular simulation conditions, the achieved transmittance is exceptional for LCDs using a power-saving mode, and can result in complete elimination of static and dynamic flickering. It is believed the result will pave the way toward successful design for low-power consumption and high-performance LCDs.
