Light weight bistable cholesteric liquid crystal displays were fabricated using 100 um flexible glass as the top and bottom substrates. The flexible glass provided better registration control compared to plastic substrates previously used in the device process. A passive matrix full-color panel using a color sharing architecture was successfully demonstrated..
Fast refresh rate is desirable for inherently slow updated passive matrix (PM) cholesteric liquid crystal display (Ch-LCD). This paper proposes a flexible cumulative drive scheme for fast and optimally refreshed PM Ch-LCD. The proposed drive scheme was experimentally verified on a 5" 100ppi PM Ch-LCD and satisfactory results were obtained.
This study reveals that the environment temperature will affect the operating voltage and the image quality of ChLCD. The data demonstrate that with the decrease of temperature the operating voltage will be increased and we found that we can maintain the operating voltage by increase the addressing time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
