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.
