Publication number: 20060262058Abstract: A high-contrast halftone image is achieved by combining drives based on right- and left-hand characteristics of cholesteric liquid crystals. A first process displays a binary image of white and black based on the right-hand characteristics of voltage-reflectance characteristics. This achieves good black with a low reflectance. A subsequent second process displays an image based on driving voltages in the left-hand characteristics. The voltages in the left-hand characteristics produce good halftone displays. At this time, the liquid crystal state makes a transition in the direction of reducing the reflectance from planar to focal conic alignment. This allows high-contrast halftone displays while maintaining a good black level obtained in the first process.Type: ApplicationFiled: November 28, 2005Publication date: November 23, 2006Applicant: MITSUBISHI DENKI KABUSHIKI KAISHAInventors: Zenichiro Hara, Noritaka Egami, Masaaki Hiraki, Yuusaku Saitou
