Multicolor Polymer Disperse Microencapsulated Liquid Crystal Displays

This work develops a new technology to fabricate polymer-dispersed microencapsulated liquid crystal (PDMLC) devices using screen-printing, which is a low temperature procedure (about 90degC) for application on a soft plastic substrate. This research demonstrates numerically and in Mandarin, a 4.5-in multicolor PDMLC (MPDMLC) device with high color contrast, low electric consumption and flexible bending mechanical property. The current work coats three different color pastes (red, blue and black) on a single substrate. Their turn-on voltages are all as low as 5 V and saturation voltages are 20, 30, and 30 V for red, blue, and black colors, respectively.
