31.3: The Fabrication of Single Substrate Multi‐Color Cholesteric Liquid Crystal Display by Ink‐Jet Printing

Abstract

We have developed a novel encapsulation method capable of producing single substrate multi‐color cholesteric liquid crystal displays patterned by ink‐jet printing. The top electrode can be printed onto thin excellent dielectric polymer layer covering Ch‐LC. A 10.4 inch bi‐stable display is successfully driven to demonstrate this proposed technique.

40.2: Novel Phototunable Chiral Materials for Single Layer Color Cholesteric Display

“…Figure 6 shows the images of test cell (cell gap is 3.9 um) with phototunable chiral compound 1a. The RGB colors are separated via cured polymeric banks in one test cell [7][8]. Color gamut of compound 1a is 40%, which is better than compound 2.…”

30.2: Single Layer Full Color Cholesteric Display

“…There are many challenges in placing pixels reflecting different colors side by side including the precise placement of the colors in a high resolution repeating pattern and keeping these colors from mixing. Approaches include; inkjet printing to individually fill mixtures of red, green and blue onto a substrate that uses polymer banks to separate the colors [5] and controlled vacuum filling of each color into the correct sub-pixels (pixelized vacuum filling) [6], among others.…”
