Novel application of ink‐jet‐printing technology in multi‐domain alignment liquid‐crystal displays

Abstract

Abstract— Based on the drop‐on‐demand characteristics of ink‐jet printing, the multi‐domain alignment liquid‐crystal display (LCD) could be achieved by using patterned polyimide materials. These polyimide ink locations with different alignment procedures could be defined in a single pixel, depending on the designer 's setting. In this paper, we combined the electro‐optical design, polyimide ink formulation, and ink‐jetting technology to demonstrate the application of multi‐domain alignment liquid‐crystal display manufactory. The first one was a multi‐domain vertical‐alignment LCD. After the horizontal alignment material pattern on the vertical alignment film, the viewing angle would reach 150° without compensation film. The second one was a single‐cell‐gap transflective LCD within integrating the horizontal alignment in the transmissive region and hybrid alignment in the reflective one in the same pixel. In addition, this transflective LCD was also demonstrated in the form of a 2.4‐in. 170‐ppi prototype.

Investigation of the interaction between rubbing cloth and pattern structure on in‐plane‐switching liquid‐crystal displays

“…have been developed. [1][2][3][4][5][6] In the quality of LCD panels, the rubbing process largely affects the black luminance, especially, rubbing scratches or defects in the rubbing cloth increase the black luminance. Thus, far, to solve these problems, many researchers have studied the surface of polyimide film and the interaction between the liquid crystals and rubbed polyimide.…”

Drying of the Silica/PVA Suspension: Effect of Suspension Microstructure

“…Coating and printing technology is important in manufacturing electronic devices such as displays, capacitors, solar cells, , and so on. Industrial coating materials such as ink, slurry, and paste form complicated microstructures because they contain various components such as particles, binders, additives, and solvents.…”
