Abstract
ABSTRACTThe electrically suppressed helix ferroelectric liquid crystal (ESHFLC) electro-optical mode is characterised by the high contrast and fast response time at low driving voltage. However, the ESHFLC demands several constraints on the alignment layer and the cell gap. However, due to the fundamental characteristics of the ferroelectric liquid crystals, the cone angle decreases at higher temperatures, which is the biggest hurdle for this electro-optical mode to find the real application. In this article, we disclose a restricted polymer stabilisation (with very small polymer concentration in the mixture) for the ESHFLC without pushing other vital parameters out of the range of the constraints for ESHFLCs. The restricted polymer-stabilised ESHFLC shows large temperature range with stable high contrast, fast response time and low driving voltage, thus, it could find application in a range of the modern display and photonic devices.
