Electrically suppressed helix ferroelectric liquid crystals for modern displays

In this article, we disclose electrically suppressed helix ferroelectric liquid crystal (ESHFLC) that is characterized by high optical quality and fast response time at the cost of extremely small driving voltage. These unique features of the ESHFLCs are highly sensitive to the anchoring energy that should be smaller and comparable to the elastic energy of the ferroelectric liquid crystal helix. The photo alignment, which offers good control on the anchoring energy by means of the irradiation energy, is critically important to lock the optimum parameters of the ESHFLC display cell. An example of field sequential color display with the frame frequency of 240 Hz at the driving voltage of 2 V has been demonstrated. In this article, we disclose the electrically suppressed helix ferroelectric liquid crystal (ESHFLC) electro-optical mode that reveals high optical quality, fast response time, and good shock stability. These unique features of the ESHFLCs strongly depend on anchoring energy that must be comparable with the elastic energy of the ferroelectric liquid crystal helix, which has been achieved by photo alignment with different irradiation energy. An example of field sequential color display with the frame frequency of 240 Hz at the driving voltage of 2 V has been demonstrated.
