Research for Innovative Display Applications

Because of the faster cycle times for technical innovations in the electronics industry, development times for appropriate liquid crystal materials also must keep pace. New liquid crystal molecules with the required characteristics are developed by molecular modeling. Thus, in the year 2005, about 600 new single compounds were made, and from these more than 8,500 liquid crystal test mixtures were developed.

Optimization of viewing angle and switching times

Apart from the need for faster switching times and requirements for ever-decreasing energy consumption, a crucial point is that LCDs should have a contrast which is independent of the viewing angle. Therefore, Merck researchers are not limited only to the development of new liquid crystals - they also assist display manufacturers in the development of new LCDs. Merck continues testing the latest generations of LC mixtures in the cell technology laboratory, seeking ever-wider viewing angles and faster response times.

New patent on In-Plane-Switching (IPS)

Some time ago, Merck, together with a partner, obtained a patent for the so-called "In-Plane-Switching". Using this method, a viewing angle of up to 176° can be attained. This is comparable to that of conventional cathode ray tube monitors so that this kind of display is particularly suitable for televisions, PC monitors, notebooks and car navigation systems.

Vertical-Alignment (VA) against color distortion

For particularly large displays, for example monitors used professionally for Computer-Aided Design (CAD) work or television sets, LC mixtures for the VA technology for improved viewing angle are also available from Merck. The result is again a viewing angle of more than 170° without loss of contrast and without color distortion.
