Photoalignment materials

To demonstrate the actual performance improvement of a dual domain LCD, a demonstrator display has been made. In this display the domains are made by patterning a photoalignment material supplied by LG Cable. This material... [Pg.138]

Several mechanisms of photoalignment reactions have been reported in the literature and hence a variety of photoalignment materials are available for director patterning. For the manufacturing of a patterned retarder applied in a transflective display (Sect. 9.4.2), we have tested two commercially avail-... [Pg.141]

There are several drawbacks for LC photoaligning materials prepared by photochemical reaction and by photodegradation in particular ... [Pg.29]

The stability of LC photoaligning materials was a major concern from the very beginning of their development as LC aligning agents [1], The stable photoaligning materials with respect to UV and IR radiation are photosensitive Pis or crosslink-able materials (see Chapter 2). [Pg.56]

The stability of azo-dye photoaligning materials can also be considerably improved by their polymerization. In order to improve their durability against light exposure and moisture, the polymerization of azo-dyes after photoalignment was investigated, synthesizing the azo-dye monomer SDAl shown in Figure 3.16 [34]. [Pg.56]
