LCD Design Techniques

Abstract

Liquid crystal displays play a crucial role in almost every application domain where the availability of smart human visual interfaces is recommended. The realization of appliances based on LCDs urges designers to develop a wide variety of technical skills and to match diverse and frequently conflicting implementation constraints. The choice of the most suitable liquid crystal technology, the proper design of the display driver electronics, as well as the conception of effective measures for built‐in removal of undesired optical artifacts are different yet outstanding aspects of LCD clever realization. Therefore, all advanced industrial LCD design flows commonly conjugate general‐purpose electronics design tools with specialized display emulation engines. Whereas the former facilitate and speed up the driver implementation, the latter are responsible for early stage evaluation of all sorts of interactions between driving equipment and back‐end liquid crystal panel, in order to curb the impact of unpractical and costly system revisions and delayed redesigns. In this view, deploying a dedicated and highly accurate physical model of the liquid crystal cell response to the applied electrical stimuli is an attractive feature, which makes the design environment significantly versatile and efficient.
