A large size panel manufacturing process for electrowetting display (EWD) by using surface treatment and ink‐jet printing (IJP) techniques had been developed. for hydrophilic rib fabrication, surface treatment technique was adopted to reinforce the adhesion of hydrophilic material on hydrophobic layer to achieve large‐Sized panel manufacturing. Also, for dosing of non‐polar liquid, IJP technique was used to dose the liquid into the unit pixel individually. By using IJP technique to dose the red, green, and blue oils, full color of EWD can be achieved without adopting color filter in the future. Here, a 6‐inch monochrome EWD prototype was successfully fabricated by using our proposed techniques.

A 10.4‐inch flexible single layer color cholesteric liquid crystal display (ChLCD) is demonstrated. The display is realized by the development of the pixelized vacuum filling (PVF) technique. The performance of the display is 3‐bit color and the resolution is QVGA. The display had passed the bending test over 10,000 times with 3 cm curvature.

Writable Cholesteric Liquid Crystal Display and the algorithm used to detect its image were developed. We could use any hard tip, ex: the tip of a forefinger, to directly write an image on the surface of Cholesteric Liquid Crystal Display (CHLCD). By measuring the capacitance of one pixel of test cell (12mm x 15mm/ 1x1), F-state or P-state could be detected. By measuring the capacitance of one pixel of 4.1" CHLCD (241um x 241um/ 320x320), F-state or P-state could not be detected, due to the effect of parasitic capacitance. Therefore, high frequency measurement and the algorithm were developed to detect the image on CHLCD.
