Driving margin

The assessment of internal attractiveness then looks at these companies from the suppHef s point of view. First of aU, how profitable is business with this customer Profitabihty needs to take into account aU the factors which drive margins for each individual customer, such as technical service at the customer site, cost through customization of products, services and aU pricing components and rebates as well as the synergy effects across the portfoHo - for example, the need for an outlet for any by-products, and so on. In some cases we even recommend pricing botdeneck resources, for example, sophisticated application services, at their opportunity cost... 

Figure 6.2.7 shows the relationship between the structure of diamine units and the driving margin. The driving margin decreases according to the decrease in the symmetry of the unit structures.

Fig. 6.2.7 Effect of polyimide molecular structure on the driving margin (M).

To obtain a large driving margin, M, or to realize high contrast of an AFLCD of high duty ratio, the selection of highly symmetric pol5mier materials with symmetrical monomeric emits is important.
