Abstract
New findings in the field of research have brought to light a unique heating effect caused by pseudo-dielectric relaxation in negative nematic liquid crystal cells. This effect, known as pseudo-dielectric heating (PDH), has often been mistakenly associated with dielectric heating (DH), which originates from the orientational relaxation in, say, dual-frequency liquid crystal (DFLC). Our recent research re-examined the heat-induced dielectric properties in DFLC cells, leading to a new understanding of both DH and PDH. Together with published results through explorations of the application of the PDH effect by multiple research groups, our knowledge of the underlying physics and the potential to utilize this unique physical phenomenon have been established for innovative applications.
