Flat Dot Matrix Display Module for Vehicle Instrumentation

Due to the recent increase in safety and operational information supplied to vehicle operators, an important need has arisen; the development of an effective display unit which uses a minimal amount of dashboard space.

A flat dot matrix LCD module is one possible satisfactory solution, but it is somewhat limited in terms of response time and viewing angle.

This paper presents a review of the recent progress and projected future trends in LCD technology as it is applied to vehicle instrumentation. In addition, the paper will discuss the design methodology, electro-optical properties, and function of three types of flat dot matrix display modules which have an intermediate number of picture elements.
